Notes to Fee and Expense Tables:1 In each Contract Year, you may surrender without a surrender charge up to 10% of the Accumulated Value existing at the timethe first surrender is made in a Contract Year; only the amount in excess of that amount (the “Excess Amount”) will be subjectto a surrender charge. A surrender charge is deducted if a full or partial surrender occurs during the first six Contract Years. Thesurrender charge is 6% during the first Contract Year and decreases by 1% each subsequent Contract Year. No surrender charge isdeducted for surrenders occurring in Contract Years seven and later. The surrender charge also will be deducted if the annuitypayments begin during the first six Contract Years, except under certain circumstances as described in Surrender Charge(Contingent Deferred Sales Charge).2 A $30 annual administrative charge is deducted on each Contract Anniversary only if, on that Contract Anniversary, the totalof premiums paid under the Contract minus all prior surrenders is less than $5,000 and the Accumulated Value is less than$5,000. The $30 fee is a Contract charge and is deducted proportionately from the Subaccounts and the Fixed Account thatmake up the Contract’s Accumulated Value.3 The current charge for the mortality and expense risk charge is equal to an annual rate of 1.10%, and we guarantee that thischarge will never exceed an annual rate of 1.25%. See Charges and Deductions—Mortality and Expense Risk Charge. A contractpending payout due to a death claim is charged based on the average daily net assets of the Variable Account and is equal to anannual rate of 0.95%.4 Thrivent Financial has agreed to reimburse certain expenses other than the advisory fees for certain Portfolios. After takingthese contractual and voluntary arrangements into account, the range (minimum and maximum) of total operating expensescharged by the Portfolios would have been 0.24% to 1.25%. The reimbursements may be discontinued at any time.5 For this example, the following assumptions are used: 1.25% mortality and expense risk charge and portfolio operatingexpenses ranging from 3.90% to 0.24%.

Each Portfolio has its own investment objective,investment program, policies and restrictions.

Differences in portfolio size, actualinvestments held, fund expenses, and other factors allcontribute to differences in Portfolio performance. Forall of these reasons, you should expect investmentresults to differ. In particular, certain Portfolios availableonly through the Contract may have names similar toportfolios not available through the Contract. Theperformance of a Portfolio not available through theContract does not indicate performance of the similarlynamed Portfolio available through the Contract.

Before selecting any Subaccount, you shouldcarefully read the accompanying prospectus forthe Fund attached to this prospectus and foundin the back of this book.

Shares of the Fund are sold to other Portfolios of theFund, to other insurance company separate accounts ofours, and to other insurance company separate accountsnot affiliated with us. The Fund may, in the future,create new Portfolios. It is conceivable that in the futureit may be disadvantageous for both variable annuityseparate accounts and variable life insurance separateaccounts to invest simultaneously in the Fund, althoughwe do not foresee any such disadvantages to eithervariable annuity or variable life insurance contractowners. The Fund’s management intends to monitorevents in order to identify any material conflictsbetween such Contract Owners and to determine whataction, if any, should be taken in response. Materialconflicts could result from, for example:

� Changes in state insurance laws;

� Changes in Federal income tax law;

� Changes in the investment management of theFund; or

� Differences in voting instructions between thosegiven by the Contract Owners from the differentseparate accounts.

If we believe the responses of the Fund to any of thoseevents or conflicts insufficiently protects ContractOwners, we may take appropriate action on our own.

In addition, we reserve the right to make otherstructural and operational changes affecting the VariableAccount.

We do not guarantee any money you place inthe Subaccounts. The value of each Subaccountwill increase or decrease, depending on theinvestment performance of the correspondingPortfolio and fees and charges under theContract. You could lose some or all of yourmoney.

Voting Privileges

To the extent required by law, we will vote the Fund’sshares held in the Variable Account at regular andspecial shareholder meetings of the Fund in accordancewith instructions received from persons having votinginterests in the corresponding Subaccounts of theVariable Account. If, however, the 1940 Act or anyregulation thereunder should be amended or if thepresent interpretation thereof should change, and as aresult we determine that we are permitted to vote theFund’s shares in our own right, we may elect to do so.

Before the Annuity Commencement Date, the ContractOwner shall have the voting interest with respect toshares of the Fund attributable to the Contract. On andafter the Annuity Commencement Date, the personentitled to receive annuity payments shall have thevoting interest with respect to such shares, which votinginterest will generally decrease during the annuityperiod.

The number of votes which a Contract Owner or personentitled to receive annuity payments has the right toinstruct will be calculated separately for eachSubaccount. The number of votes which each ContractOwner has the right to instruct will be determined bydividing a Contract’s Accumulated Value in aSubaccount by the net asset value per share of the

The numberof votes of the Portfolio which the Contract Owner orperson entitled to receive annuity payments has right toinstruct will be determined as of the date coincidentwith the date established by the Portfolio fordetermining shareholders eligible to vote at the meetingof the Fund. Voting instructions will be solicited bywritten communication prior to such meeting inaccordance with procedures established by the Fund.

Any Portfolio shares held in the Variable Account forwhich we do not receive timely voting instructions, orwhich are not attributable to Contract Owners, will bevoted by us in proportion to the instructions receivedfrom all Contract Owners. Any Portfolio shares held byus or our affiliates in General Accounts will, for votingpurposes, be allocated to all separate accounts of oursand our affiliates having a voting interest in thatPortfolio in proportion to each such separate account’svotes. Voting instructions to abstain on any item to bevoted upon will be applied on a pro rata basis to reducethe votes eligible to be cast.

Each person having a voting interest in a Subaccountwill receive proxy materials, reports and other materialsrelating to the appropriate Portfolio.

Fixed Account

On or before the Annuity Commencement Date, youmay allocate the premiums paid under the Contract andtransfers from the Subaccounts to the Fixed Account.After the Annuity Commencement Date, you may nolonger transfer out of the Fixed Account. Any amountsallocated to the Fixed Account are invested with ourgeneral account assets. Interest will be credited onpremiums allocated to the Fixed Account and onamounts transferred to the Fixed Account from the dateof allocation or transfer. The initial interest rate for each

such allocation or transfer is guaranteed for 12 months,and subsequent interest rates will not change morefrequently than every 12 months. Interest will becompounded daily and will never be less than aneffective annual interest rate of 4% per year.

In any Contract Year, only one of your allowed transfersmay be from the Fixed Account. Any transfer from theFixed Account must be made on or within 45 days aftera Contract Anniversary.

Because of exemptive and exclusionary provisions,interests in the Fixed Account have not been registeredunder the Securities Act of 1933 (“1933 Act”), and theFixed Account has not been registered as an investmentcompany under the Investment Company Act of 1940(“1940 Act”). Accordingly, neither the Fixed Account,nor any interests therein are generally subject to theprovisions of the 1933 or 1940 Acts. Disclosuresregarding the Fixed Account, however, may be subjectto certain generally applicable provisions of the federalsecurities laws relating to the accuracy andcompleteness of statements in prospectuses.

Contract Owners have no voting rights in the VariableAccount with respect to Fixed Account values.

A Maintenance of Solvency provision is a legalrequirement of a fraternal benefit society. Please seeMaintenance of Solvency for more information.

The Maintenance of Solvency provision applies to theFixed Account in this Contract. The provision is onlyinvoked in the event the reserves of our fraternal benefitsociety become impaired. If our reserves becomeimpaired, you may be required to make an extrapayment. Our Board of Directors will determine theamount of any extra payment based on each member’sfair share of the deficiency. If the payment is not madewithin 60 days from the date we notify you, it will becharged as a debt against the Contract with interestcompounded at a rate of 5% per year. You may choosean equivalent reduction in benefits instead of or incombination with the debt.

RISKS••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••

This annuity has some risks which may include thefollowing:

� The investment options you choose may lose value,and the Accumulated Value of your contract can godown;

� In addition to taxes on gain, there may be a taxpenalty if you withdraw money from the annuityprior to age 591⁄2;

� If you elect a Settlement Option, you will onlyreceive periodic annuity payments as frequently asyou selected. There is a risk that your annuitypayments will not keep pace with your personalexpenses. If you choose a life income with noguaranteed period, there is a risk that you will dieprematurely, and no death proceeds will be paid toyour beneficiaries.

� Health Crisis Risk. The global pandemicoutbreak of the novel coronavirus known asCOVID-19 has resulted in substantial marketvolatility and global business disruption. Theduration and full effects of the outbreak areuncertain and may result in trading suspensionsand market closures, limit liquidity and the abilityof the Fund to process contract owner redemptions,and negatively impact Fund performance. TheCOVID-19 outbreak and future pandemics couldaffect the global economy in ways that cannot beforeseen and may exacerbate other types of risks,negatively impacting the value of the Fund.

THE CONTRACT••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••

Allocation of Premium

We will allocate the premiums among the Subaccount(s)and/or the Fixed Account according to the instructionsyou provided in your application for the Contract orsubsequently. We reserve the right to limit the numberof allocations to subaccounts.

The allocation percentages which you select must be inwhole numbers and their sum must be 100%. Wereserve the right to adjust allocation percentages toeliminate fractional percentages. Premiums which youpay are allocated at the end of the Valuation Period inwhich we receive them using the allocation percentagesyou have specified. You may change the allocationpercentages for future premiums without charge and atany time by giving us Written Notice or over thetelephone if we receive proper authorization from you.Any change will apply to all future premiums unless yourequest another change.

The values in the Subaccounts of the Variable Accountwill vary with the investment experience of thecorresponding Portfolios. You bear the entireinvestment risk of the amounts allocated toSubaccounts of the Variable Account. You shouldperiodically review your allocations of premiums inlight of market conditions and your overall financialobjectives.

Accumulated Value of Your Contract

On or before the Annuity Commencement Date, yourContract’s value is expressed as its Accumulated Value.Your Contract’s Accumulated Value is the sum of theaccumulated values in Subaccounts and the FixedAccount.

Your Contract’s Accumulated Value will reflect theinvestment experience of the chosen Subaccounts, anyamount of value in the Fixed Account, any premiumsthat you pay, any surrenders you make, and any chargeswe assess in connection with the Contract. There is noguaranteed minimum Accumulated Value, and, becausea Contract’s Accumulated Value on any future datedepends upon a number of variables, it cannot bepredetermined.

Subaccount Valuation

On any Valuation Day, the Accumulated Value of yourinvestment in a Subaccount is equal to the number ofAccumulation Units attributable to that Subaccountmultiplied by the Accumulation Unit Value for thatSubaccount. On any day that is not a Valuation Day, theAccumulated Value for a Subaccount will be determinedon the next Valuation Day.

Accumulation Units. Transactions in and out of aSubaccount are made by crediting or reducing theAccumulation Units of the Subaccount.

We credit your Contract with Accumulation Units in aSubaccount when:

� You allocate premiums to that Subaccount;

� You transfer Accumulated Value into thatSubaccount from another Subaccount or the FixedAccount.

We reduce the Accumulation Units in a Subaccountwhen:

� You transfer Accumulated Value out of thatSubaccount into another Subaccount or the FixedAccount;

� You make a surrender from that Subaccount; or

� We deduct all or part of the administrative chargefrom that Subaccount.

Accumulation Unit Value. A Subaccount’sAccumulation Unit Value is the unit price that is usedwhenever we credit or reduce Accumulation Units of theSubaccount. We re-determine the Accumulation UnitValue for each Subaccount at the end of each ValuationPeriod. At the end of each Valuation Period, theAccumulation Unit Value for a Subaccount is equal to(a) multiplied by (b) where:

(a) Is the Accumulation Unit Value for thatSubaccount at the end of the prior ValuationPeriod.

(b) Is the Net Investment Factor for thatSubaccount for that period.

Net Investment Factor

The Net Investment Factor for a Subaccount measuresinvestment performance of that Subaccount. The NetInvestment Factor for a Subaccount for a ValuationPeriod is determined by dividing (a) by (b) and thensubtracting (c) where:

(a) Is the sum of:

(i) The net asset value per share of thecorresponding Portfolio of the Subaccountat the end of the Valuation Period; plus

(ii) The per share amount of any dividend orcapital gain distribution made by thePortfolio if the “ex-dividend” date occursduring the Valuation Period; plus or minus.

(iii) A per share charge or credit for any taxesreserved for that we determine to be aresult of the investment operation of thePortfolio.

(b) Is the net asset value per share of thecorresponding Portfolio of the Subaccount atthe end of the prior Valuation Period.

(c) Is the mortality and expense risk charge wededuct for each day in the Valuation Period andis based upon the total Accumulated Value inthe Subaccount. The mortality and expense riskcharge is currently 1.10% and guaranteed neverto exceed 1.25%.

Minimum Accumulated Value

We require your Contract to maintain a minimumAccumulated Value. The amount which must bemaintained depends on your premium paying history asfollows:

(1) At the end of any 24-month period in whichyou pay no premiums, your Accumulated Valuemust be at least $1,000 after all Contractcharges have been applied.

(2) If you pay at least one premium every24-months, we require only that theAccumulated Value always be sufficient tocover the Contract’s administrative charge.

If we know that your Contract will not meet theserequirements on an upcoming Contract Anniversary, wewill notify you 60 days before that anniversary andinform you of the minimum dollar amount which youmust pay to keep the Contract in force. If you fail to payat least that amount, we will terminate your Contracton the Contract Anniversary. If we do so because yourContract failed to meet Requirement (1) above, we willpay you the remaining Accumulated Value. If yourContract fails to meet Requirement (2) above, yourContract terminates without value.

Death Benefit Before the AnnuityCommencement Date

If the Annuitant dies before the AnnuityCommencement Date, the beneficiary will be entitled toreceive the Contract’s death benefit.

The amount of the death benefit will be the greatest of:

� The Accumulated Value on the date we calculatethe death benefit;

� The sum of all premiums we received for theContract, less the amount of all partial surrenders(including any applicable charges) which youmade; and

� The Accumulated Value on the precedingMinimum Death Benefit Date plus the sum of thepremiums we received for the Contract after thatdate, less the amount of any partial surrenders(including any applicable charges) which you madeafter that date.

The Minimum Death Benefit Dates occur every six yearson the Contract Anniversary.

We calculate the death benefit at the end of theValuation Period during which we receive at our ServiceCenter satisfactory proof of the death of an Annuitant.Any amount of the death benefit in excess of theAccumulated Value will be allocated to the Subaccountsand the Fixed Account according to the ratio of theAccumulated Value in each to the Accumulated Value inthe Contract. Once calculated, death proceeds maycontinue to be subject to the investment experience ofthe Variable Account. When based on the investmentexperience of the Variable Account, death proceeds may

increase or decrease daily and are not guaranteed for aminimum dollar amount. Surrender charges do notapply to death proceeds.

If the beneficiary requests a single sum payment, we willpay the death proceeds within seven days after the datewe calculate them. If the beneficiary requests asettlement option, it must be an option that you couldhave selected before the Annuity Commencement Date,and the option must provide that either:

(1) The principal and interest are completelydistributed within five years after the date ofdeath; or

(2) If the beneficiary is a natural person,distribution of the principal and interest ismade by means of a periodic payment whichbegins within one year after the date of deathand is not guaranteed for a period whichextends beyond the life expectancy of thebeneficiary.

Any proceeds not subsequently withdrawn will be paidin a lump sum on the date five years after the date ofdeath.

If an Annuitant dies before annuity payments begin andthat Annuitant’s Spouse is the sole primary beneficiary,he or she may, to the extent permitted by law and theContract, elect to continue the Contract in force, inwhich case the surviving Spouse will become and betreated as the Annuitant and owner effective on thedate that the death proceeds are calculated (“ExchangeDate”). Any amount of death proceeds in excess of theAccumulated Value of the Contract will be allocated tothe Subaccounts and the Fixed Account according to theratio of the Accumulated Value in each to theAccumulated Value of the Contract. Where allowed bythe Contract, the Spouse will have 60 days from thedate we receive proof of your death in which to elect toreceive proceeds or to continue the Contract. If anelection to receive death proceeds or to continue theContract is not made within 60 days, the survivingSpouse will be deemed to have elected to continue theContract effective on the Exchange Date. If thesurviving Spouse elects to continue the Contract, thedeath benefit will be determined according to yourContract based on the Accumulated Value on theExchange Date.

If your Contract was issued in connection with aQualified Plan, additional restrictions on the manner ofpayment of the death benefit may apply. Any suchrestrictions will be stated in the Contract or the plandocuments. Purchasers acquiring contracts pursuant toQualified Plans should consult qualified pension or taxadvisers.

Death Benefit After the AnnuityCommencement Date

If the Annuitant dies while we are paying you anannuity income under a settlement option, any deathbenefit payable will depend on the terms of thesettlement option. If a death benefit is payable, thebeneficiary may elect to receive the proceeds in theform of a settlement option, but only if the paymentsare paid at least as rapidly as payments were being paidunder the settlement option in effect on the date ofdeath. If your Contract was issued in connection with aQualified Plan, additional restrictions on the manner ofpayment of the death benefit may apply.

Surrender

On or before the Annuity Commencement Date, youmay surrender all or part of your Contract’sAccumulated Value. The surrender or partial surrenderwill not be processed until we receive your surrenderrequest at our Service Center, in good order. Anysurrender which you request will be made at the end ofthe Valuation Period during which the requirements forsurrender are completed. We will pay you the proceedsfrom a surrender within seven days after the surrender ismade. The proceeds will be the amount surrendered lessany surrender charge. See Charges and Deductions—Surrender Charge (Contingent Deferred Sales Charges).

A surrender reduces your Accumulated Value by theamount surrendered. For amounts surrendered from aSubaccount, this is done by selling Accumulation Unitsof the Subaccount. For partial surrenders, we allocatethe surrender among the Subaccounts and the FixedAccount so that all accounts are reduced in value by thesame percentage. With our approval, you may specify adifferent allocation for a partial surrender. If you haveless than the amount of the allocation, we will allocate

the partial surrender among the Subaccounts and theFixed Account so that all accounts are reduced in valueby the same percentage.

A partial surrender must be at least $200, unless it isbeing used to pay a premium or loan on anotherThrivent product, and must not reduce the remainingAccumulated Value to less than $1,000. (If the amountyou request as a partial surrender would reduce theremaining Accumulated Value to less than $1,000, wemay contact you to determine whether you would like apartial surrender of an amount that would result inremaining Accumulated Value of at least $1,000 orwhether instead you would like to make a full surrenderof your Contract. If we are unable to contact you withinseven days, we reserve the right to treat your request asa request for a full surrender.) When you request apartial surrender, you specify the amount which youwant to receive as a result of the surrender. If there areno surrender charges, or tax withholding associatedwith the surrender, the amount surrendered will be theamount which you request. Otherwise, the amountsurrendered will be the amount necessary to provide theamount requested after we apply the surrender chargeand any withholding. You may make partial surrendersby telephone. (Contracts used in a tax-sheltered annuityunder Section 403(b) of the Internal Revenue Code willbe subject to certain restrictions regarding surrenders.See Federal Tax Status—Qualified Plans.) Any surrenderwhich you request will be made at the end of theValuation Period during which the requirements forsurrender are completed. We will pay you the proceedsfrom a surrender within seven days after the surrender ismade.

After the Annuity Commencement Date, your Contractdoes not have an Accumulated Value which can besurrendered. However, if you are receiving annuitypayments under certain settlement options, surrendermay be allowed. Surrender is not allowed if you agreednot to revoke or change the option once annuitypayments begin. For other settlement options, theamount available for surrender will be the commutedvalue of any unpaid annuity payments computed onthe basis of the assumed interest rate incorporated inthe annuity payments.

You must have a Medallion Signature Guarantee if youwant to surrender or withdraw a value of $500,000 ormore. Certain surrender requests of less than $500,000require either a Medallion Signature Guarantee, anotarized signature, or an attestation of your signatureby a financial professional. These authenticationprocedures are designed to protect against fraud. Suchan authentication procedure may be required for:

� Surrender of a value of $100,000 or more;

� Request to withdraw or surrender if there has beena change of address on the account within thepreceding 15 days; and

� Certain other transactions as determined by us.

A Medallion Signature Guarantee is a stamp provided bya financial institution that guarantees your signature.You sign the Thrivent approved form and have thesignature(s) guaranteed by an eligible guarantorinstitution such as a commercial bank, trust company,brokerage firm, credit union, or a savings bankparticipating in the Medallion Signature GuaranteeProgram. We may waive the Medallion SignatureGuarantee in limited circumstances. A Notary Public isan individual who is authorized to authenticatesignatures and can be found in law firms or many of thesame places that an individual who provides MedallionSignature Guarantees can be found. Attestation by afinancial professional requires the verification andwitness of your signature by a financial professional.

A partial surrender or surrender may result in adversetax consequences, including the imposition of a 10%federal premature distribution penalty. For allsurrenders, you should consider the tax implications ofa surrender before you make a surrender request. SeeFederal Tax Status.

You can request a transfer in two ways:

(1) By giving us Written Notice; or

(2) By telephone.

We will make the transfer without charge at the end ofthe Valuation period during which we receive yourrequest. For transfers from the Fixed Account to aSubaccount of the Variable Account, the amount takenfrom the Fixed Account is used to buy AccumulationUnits of the chosen Subaccount. For transfers from aSubaccount, Accumulation Units of the Subaccount aresold and the resulting dollar amount is, depending onyour request, either transferred to the Fixed Account orused to buy Accumulation Units of another Subaccount.

Transfers are subject to the following conditions:

� The total amount transferred must be at least $200.However, if the total value in a Subaccount or theFixed Account is less than $200, the entire amountmay be transferred.

� We reserve the right to limit the number oftransfers in each Contract Year. However, we willalways allow at least 12 transfers per Contract Year.We consider all amounts transferred in the sameValuation Period to be one transfer. It is notdependent upon the number of originating ordestination Subaccounts.

� In any Contract Year, only one of your allowedtransfers may be from the Fixed Account. Anytransfer from the Fixed Account must be made onor within 45 days after a Contract Anniversary.

Transfers will also be subject to any conditions that maybe imposed by the Portfolio whose shares are involved.

After the Annuity Commencement Date, you maychange the percentage allocation of variable annuitypayments among the available Subaccounts;

(1) By giving us Written Notice; or

(2) By telephone if we receive properauthorization from you.

Frequent Trading Policies

Because short-term or frequent transfers, purchases andredemptions of Contract value among Subaccounts poserisks to Contract Owners, we place limits on frequenttrading practices. Such risks include potentiallyimpaired investment performance due to disruption ofportfolio management strategies, increased transactionscosts, and dilution of fund shares (and therefore unitvalues) thereby negatively impacting the performance ofthe corresponding Subaccount.

We have policies and procedures to discourage frequenttransfers of value among Subaccounts. We usereasonable efforts to apply the policies and proceduresuniformly. Several different tactics are used to detectand prevent excessive trading within the Subaccounts.

As described in other sections, we impose a fee if thetransfers made within a given time period exceed amaximum contractual number. See Fee Tables

We also use a combination of monitoring ContractOwner activity and further restricting certain ContractOwner transfers based on a history of frequent transfersamong Subaccounts. When monitoring Contract Owneractivity, we may consider several factors to evaluatetransfer activity including, but not limited to, theamount and frequency of transfers, the amount of timebetween transfers and trading patterns. In making thisevaluation, we may consider trading in multipleContracts under common ownership or control.

Exceptions may apply to Dollar Cost Averaging,automatic investment plans, systematic withdrawalplans or non-abusive re-balancing. We reserve the right,in our sole discretion, to identify other trading practicesas abusive.

If we determine that you are engaging in excessivetrading activity, we will request that you cease suchactivity immediately. If we determine that you arecontinuing to engage in excessive trading, we willrestrict your Contract so that you can make transfers ononly one business day each calendar month and anysuch transfers must be separated by at least 20 calendardays. We reserve the right to reject or restrict anytransfer request, without notice for any reason.

In addition, the underlying Portfolios may have adoptedrestrictions designed to discourage frequent tradingpractices, and we reserve the right to enforce thesepolicies and procedures.

Although we seek to deter and prevent frequent tradingpractices, there are no guarantees that all activity can bedetected or prevented. Contract Owners engaging insuch trading practices use an evolving variety ofstrategies to avoid detection and it may not be possiblefor operational and technological systems to reasonablyidentify all frequent trading activity. Contract Ownersstill may be subject to their harmful effects if Thrivent isunable to detect and deter abusive trading practices.

Dollar Cost Averaging

You may establish a dollar cost averaging program tomake periodic transfers of at least the minimum amountrequired from the Thrivent Money Market Subaccountto the other Subaccounts except the Fixed Account. Ifthe remaining amount to be transferred drops below theamount you established, the entire remaining balancewill be transferred on the next transfer date and thedollar cost averaging program will terminate. Transferswill be made automatically on the date you choose(except the 29th, 30th, or 31st of a month). Transferswill continue until the entire amount in the ThriventMoney Market Subaccount has been depleted or untilyou notify us to discontinue the program. In order tobegin, terminate or resume the program, we mustreceive Written Notice or notice by telephone (if youhave such authorization).

Asset Rebalancing

On or before the Annuity Date, you may participate inan optional asset rebalancing program that allows youto elect a specific asset allocation to maintain over time.The sum of the rebalancing percentages must be 100%and each rebalancing allocation percentage must be awhole number not greater than 100%. You may selectany date (except the 29th, 30th, or 31st of a month) tobegin the asset rebalancing program and whether tohave your Subaccounts reallocated semiannually orannually. The rebalancing will be done after all othertransfers and allocations to or from the Subaccounts forthe Valuation Day. The asset rebalancing program doesnot allow you to include the Fixed Account Allocation

in the rebalancing program. To participate in the assetrebalancing program, complete the Asset RebalancingForm at the time of your application or call1-800-847-4836 to request an Asset Rebalancing Form.

Telephone and Online Transactions

You may perform certain transactions online or over thetelephone.

We have adopted reasonable security procedures toensure the authenticity of instructions, includingrequiring identifying information, recording telephoneconversations and providing written confirmations oftransactions.

Assignments

Assignment is the transfer of Contract ownership fromone party to another. If a Contract is used in a QualifiedPlan and the Contract Owner is a trust, custodian oremployer, then the Contract Owner may transferownership to the Annuitant. Otherwise, the Contractmay not be sold, assigned, discounted or pledged ascollateral for a loan or as security for performance of anobligation or for any other purpose to any person otherthan us.

If the Contract is not used in a Qualified Plan, thenownership may be transferred, but not to a naturalperson, and the Contract may be assigned as collateral.

We are not bound by an assignment unless it is inwriting and filed at our Service Center. We are notresponsible for the validity or effect of any assignment.

You should consider the tax implications of anassignment. See Federal Tax Status.

Contract Owner, Beneficiaries and Annuitants

Unless another owner is named in the application, theAnnuitant is the owner of the Contract and mayexercise all of the owner’s rights under the Contract.

The Contract Owner may name a beneficiary to receivethe death benefit payable under the Contract. If thebeneficiary is not living on the date payment is due or ifno beneficiary has been named, the death benefit willbe paid to the estate of the Annuitant.

The owner may change the beneficiary by giving usWritten Notice of the change. The change will not beeffective until we receive your Written Notice at ourService Center. Once we receive it, the change will beeffective as of the date on which you signed the notice.However, the change will not affect any payments madeor actions taken by us before we received your notice,and we will not be responsible for the validity of anychange.

We do not deduct a charge for sales expenses frompremiums at the time premiums are paid. Instead, wededuct a charge at the time you surrender all or part ofyour Accumulated Value. This surrender charge appliesonly during the first six Contract Years. During thoseyears, we calculate the surrender charge as a percentageof the amount which you surrender, subject to certainexceptions noted below.

After Contract Year six there is no charge for makingsurrenders. In addition, during the first six ContractYears we will limit or waive surrender charges as follows:

� Cumulative Percent-of-Premium Limit. Forall surrenders, we will limit the surrender charge sothat on any date, the sum of all surrender chargesapplied to that date will not exceed 6.5% of thetotal of premiums you have paid to that date.

� Surrenders Paid Under Certain SettlementOptions. For surrenders which you make afterContract Year three, there is no surrender chargeapplied to amounts which you elect to have paidunder:

(1) A settlement option for a fixed amount or afixed period (including Option 3V describedunder Annuity Provisions—Settlement Options) ifthe payment period and the accumulationperiod will equal or exceed the surrender chargeperiod and you agree at the time of settlementthat after the first payment is made, you maynot revoke or change the settlement option.

(2) Options which involve a life income,including Option 4V described under AnnuityProvisions—Settlement Options.

� Ten Percent Free Each Contract Year. In eachContract Year, you may surrender without asurrender charge up to 10% of the AccumulatedValue existing at the time of your first surrendermade in that Contract Year. This “Ten Percent Free”is not cumulative. For example, if you make nosurrenders during the first three Contract Years, thepercentage of Accumulated Value which you maysurrender without charge in the fourth ContractYear is 10%, not 40%.

� Total Disability of the Annuitant. There is nosurrender charge if the Annuitant is totally disabled(as defined in your Contract) on the date of asurrender.

� Series of Substantially Equal PeriodicPayments for Life. There is no surrender chargeif you receive payments made as one of a series ofsubstantially equal periodic payments for your lifeor your life expectancy or the joint lifeexpectancies of you and your beneficiary made notless frequently than annually.

Certain surrenders are subject to a 10% Federal taxpenalty on the amount of income withdrawn. SeeFederal Tax Status.

If surrender charges are not sufficient to cover our salesexpenses, we will bear the loss; conversely, if theamount of such charges proves more than enough, wewill retain the excess. See Sufficiency of Charges below.We do not currently believe that the surrender chargeswe impose will cover our expected costs of distributingthe Contracts.

Administrative Charge

Your Contract includes an annual administrative chargeof $30 (or less, if required by the state where yourContract is issued) to help us cover the expenses weincur in administrating your Contract, the VariableAccount and the Subaccounts. On each ContractAnniversary prior to and including the AnnuityCommencement Date, we will determine if this chargewill be applied to your Contract. We apply the chargeonly on Contract Anniversaries on which the sum ofpremiums you have paid less the amount of any partialsurrenders you have made is less than $5,000 and theAccumulated Value is less than $5,000. We deduct thecharge from your Accumulated Value, allocating thededuction among the Subaccounts and the FixedAccount so that all accounts are reduced in value by thesame percentage. Any such deduction from aSubaccount is made by selling Accumulation Units ofthe Subaccount. With our approval, you may specify adifferent allocation for the administrative charge.

Mortality and Expense Risk Charge

We assume certain financial risks associated with theContracts. Those risks are of two basic types:

� Mortality Risk. This includes our risk that (1)death benefits paid before the AnnuityCommencement Date will be greater than theAccumulated Value available to pay those benefits,and (2) Annuitant payments involving life incomeswill continue longer than we expected due to lowerthan expected death rates of the persons receivingthem.

� Expense Risk. This is the risk that the expenses,with respect to the Contracts, will exceed Contractcharges.

Page 37: THRIVENT FLEXIBLE PREMIUM DEFERRED VARIABLE ANNUITY · 2020-04-30 · THRIVENT VARIABLE ANNUITY ACCOUNT C THRIVENT SERIES FUND,INC. PROSPECTUS FOR FLEXIBLE PREMIUM DEFERRED VARIABLE

As compensation for assuming these risks, we deduct adaily mortality and expense risk charge from theaverage daily net assets in the Variable Account. Thecurrent charge (0.003014% per day) is equal to anannual rate of 1.10% of the average daily net assets ofeach Subaccount in the Variable Account during theaccumulation period. Contracts pending payout due toa death claim are charged at an annual rate of 0.95%.We may change this charge in the future, but weguarantee that it will never exceed an annual rate of1.25% (0.003425% per day).

If the mortality and expense risk charge is insufficient tocover the actual cost of the mortality and expense riskassumed by us, we will bear the loss. We will not reduceannuity payments or increase the administrative chargeto compensate for the insufficiency. If the mortality andexpense risk charge proves more than sufficient, theexcess will be profit available to us for any appropriatecorporate purpose including, among other things,payment of sales expenses. See Sufficiency of Chargesbelow.

Notwithstanding this charge, Contract Owners may beasked to add money under the Maintenance of Solvencyprovision described in the General Provisions –Maintenance of Solvency section.

Expenses of the Fund

Because the Variable Account purchases shares of theFund, the net assets of the Variable Account will reflectthe investment advisory fees or other expenses incurredby the Fund. See Fee and Expense Tables and theaccompanying current prospectus of the Fund.

Other Taxes

Currently, no charge will be made against the VariableAccount for Federal income taxes. We may, however,make such a charge in the future if income or gainswithin the Variable Account will result in any Federalincome tax liability to us. Charges for other taxes, ifany, attributable to the Variable Account may also bemade. See Federal Tax Status.

Sufficiency of Charges

If the amount of all charges assessed in connection withthe Contracts as described above is not enough to coverall expenses incurred in connection therewith, we willbear the loss. Any such expenses borne by us will bepaid out of our general account which may include,among other things, proceeds derived from mortalityand expense risk charges deducted from the VariableAccount. Conversely, if the amount of such chargesproves more than enough, we will retain the excess.

If our reserves become impaired, Contract Owners maybe asked to add money under the Maintenance ofSolvency provision described in General Provisions –Maintenance of Solvency section.

ANNUITY PROVISIONS••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••

Annuity Commencement Date

The Annuity Commencement Date is the date on whichwe begin paying you your Contract’s annuity income.This date is based on the maturity age which you specifyin your application. You may change the AnnuityCommencement Date by giving us notice in writing orby telephone before both the Annuity CommencementDate currently in effect and the new AnnuityCommencement Date. The new date selected mustsatisfy our requirements for an AnnuityCommencement Date and any requirements that maybe imposed by the state in which your Contract wasissued. At the Annuity Commencement Date stated inyour Contract, we may, at our discretion, allow you toextend the Annuity Commencement Date.

Your Contract provides for a death benefit if theAnnuitant dies before the Annuity CommencementDate. After the Annuity Commencement Date, amountspayable, if any, depend upon the terms of thesettlement option

Annuity Proceeds

The proceeds available on the Annuity CommencementDate will be the amount provided by surrendering yourContract’s Accumulated Value on that date. If theAnnuity Commencement Date occurs within the firstsix Contract Years, surrender charges will be deductedfrom the Accumulated Value if they apply.

We will pay you the proceeds at maturity according tothe annuity settlement option which you select.However, we will pay the proceeds in a single sum if theAccumulated Value on the Annuity CommencementDate is less than $2,000 or if you elect to receive theproceeds in a single sum. If we pay you proceeds in asingle sum, your Contract will terminate on the AnnuityCommencement Date.

If you have not selected either a settlement option or asingle sum payment by the Annuity CommencementDate, we will pay proceeds of $2,000 or more using afixed annuity, life income with 10-year guaranteeperiod.

Settlement Options

You may elect to have proceeds paid to you under anannuity settlement option or a combination of options.Under each option, you may choose whether annuitypayments are to be made on a fixed or variable basis.

We reserve the right to limit the number of allocationsto subaccounts.

The fixed annuity settlement options available to youare described in your Contract but are not summarizedhere. The variable annuity settlement options whichyour Contract offers are as follows:

� Option 3V—Income for a Fixed Period. Underthis option, we pay an annuity income for a fixednumber of years, not to exceed 30.

� Option 4V—Life Income with GuaranteedPeriod. Under this option, we pay an annuityincome for the lifetime of the payee. If the payeedies during the guaranteed period, payments willbe continued to the end of that period and will bepaid to the beneficiary. You may select a guaranteedperiod of 10 or 20 years or other guaranteed periodagreed to by us.

In addition to these options, proceeds may be paidunder any other settlement option agreeable to us.

Partial Annuitization

Federal tax law permits taxpayers to annuitize a portionof their annuity while leaving the remaining balance taxdeferred. You may elect to have a portion of yourproceeds ($2,000 or more) paid to you under an annuitysettlement option or a combination of options. Thesettlement option(s) must be for a fixed amount or fixedperiod payable for at least ten years, or a single or jointlife income with or without a guaranteed period, or anyother option agreeable to us. If this requirement is met,the settlement option and the tax-deferred balance willgenerally be treated as two separate contracts for incometax purposes only. Your after-tax premiums in yourcontract will be allocated pro-rata between thesettlement option and the portion that remainsdeferred.

Frequency of Annuity Payments

Annuity payments under a settlement option will bepaid at monthly intervals unless you and we agree to adifferent payment schedule. If annuity payments wouldbe or become less than $25 ($20 for Contracts issued inthe state of Texas) if a single settlement option ischosen, or $25 ($20 for Contracts issued in the state ofTexas) on each basis if a combination of variable andfixed options is chosen, we may change the frequencyof payments to intervals that will result in payments ofat least $25 ($20 for Contracts issued in the state ofTexas) each from each option chosen.

Amount of Variable Annuity Payments

The amount of the first variable annuity payment isdetermined by applying the proceeds to be paid under aparticular settlement option to the annuity table in theContract for that option. The table shows the amount ofthe initial annuity payment for each $1,000 applied.

Subsequent variable annuity payments vary in amountaccording to the investment experience of the selectedSubaccount(s). Assuming annuity payments are basedon the unit values of a single Subaccount, the dollaramount of the first annuity payment (as determinedabove) is divided by the Annuity Unit Value as of theAnnuity Commencement Date to establish the numberof Annuity Units representing each annuity payment.This number of Annuity Units remains fixed during theannuity payment period. The dollar amount of thesecond and subsequent variable annuity payments isnot predetermined and may change from payment topayment. The dollar amount of the second and eachsubsequent variable annuity payment is determined bymultiplying the fixed number of Annuity Units by theAnnuity Unit Value with respect to such Subaccount atthe end of the last Valuation Date of the period withrespect to which the payment is due. See SubaccountAnnuity Unit Value below. If the payment is based uponthe Annuity Unit Values of more than one Subaccount,

the procedure described here is repeated for eachapplicable Subaccount and the sum of the paymentsbased on each Subaccount is the amount of the annuitypayment.

The annuity tables in the Contracts are based on themortality table specified in the Contract. Under thesetables, the longer the life expectancy of the Annuitantunder any life annuity option or the duration of anyperiod for which payments are guaranteed under theoption, the smaller will be the amount of the firstmonthly variable annuity payment. We guarantee thatthe dollar amount of each variable annuity paymentafter the first payment will not be affected by variationsin expenses or in mortality experience from themortality assumptions used to determine the firstpayment.

Subaccount Annuity Unit Value

A Subaccount’s Annuity Unit Value is used to determinethe dollar value of annuity payments based on AnnuityUnits of the Subaccount. Annuity Unit Values mayincrease or decrease during each Valuation Period. Were-determine the Annuity Unit Value for eachSubaccount at the end of each Valuation Period. Theinitial Annuity Unit Value for a Subaccount was equal tothe initial Accumulation Unit Value for thatSubaccount. At the end of any subsequent ValuationPeriod, each Subaccount’s Annuity Unit Value is equalto (a) x (b) x (c) where:

(a) Is that Subaccount’s Annuity Unit Value at theend of the immediately preceding ValuationPeriod.

(b) Is that Subaccount’s Net Investment Factor forthe current Valuation Period. See The Contract—Subaccount Valuation—Net Investment Factordescribed earlier in this Prospectus.

(c) Is a discount factor equivalent to an assumedinvestment earnings rate of 3.5% per year.

In 1983, the U.S. Supreme Court held in ArizonaGoverning Committee v. Norris that the application ofsex-distinct actuarial tables to employees based upontheir gender in calculating the amount of retirementbenefits violates Title VII of the Civil Rights Act of 1963.Because of this decision, employer-sponsored retirementplans may not use sex-distinct actuarial annuity rates indetermining benefits.

Generally, annuity payments described in thisProspectus are determined using sex-distinct actuarialtables based on the Annuitant’s gender. However,annuity payments will be based on a gender neutralbasis for the following:

� Contracts used in an employer sponsoredretirement plan;

� Contracts issued in Massachusetts (beginningJanuary 1, 2009); and

FEDERAL TAX STATUS••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••

General

The following discussion of the federal income taxtreatment of the Contract is not exhaustive, does notpurport to cover all situations, and is not intended astax advice. The federal income tax treatment of theContract is unclear in certain circumstances, and aqualified tax advisor should always be consulted withregard to the application of law to individualcircumstances. This discussion is based on the InternalRevenue Code of 1986, as amended (the “Code”),Treasury Department regulations, and interpretationsexisting on the date of this Prospectus. Theseauthorities, however, are subject to change by Congress,the Treasury Department, and judicial decisions.

This discussion does not address any federal estate orgift tax consequences, or any state or local taxconsequences, associated with the Contract. In addition,we make no guarantee regarding any tax treatment—federal, state, or local—of any Contract or anytransaction involving a Contract.

Tax Status of the Variable Account

The Variable Account is not separately taxed as a“regulated investment company” under the Code, butrather is treated as our separate account. Under currentlaw, both the investment income and realized capitalgains of the Variable Account (i.e., the income andcapital gains distributed to the Variable Account by theFund) are reinvested without taxation to us. However,we reserve the right in the future to make a chargeagainst the Variable Account or the Accumulated Valueof a Contract for any federal, state, or local income taxesthat we incur and determine to be attributable to theVariable Account or the Contract.

Taxation of Annuities in General

The following discussion assumes that the Contract isnot used in connection with a Qualified Plan.

Tax Deferral During Accumulation Period

In general, under current law, an increase in a Contract’sAccumulated Value is not taxable to the ContractOwner until received, either in the form of annuityincome payments as contemplated by the Contract orin some other form of distribution. However, this rule

applies only if: (1) the investments of the VariableAccount are “adequately diversified” in accordance withTreasury Department regulations; (2) the Company,rather than the Contract Owner, is considered theowner of the assets of the Variable Account for federalincome tax purposes; (3) the Contract Owner is anindividual (or an individual is treated as the ContractOwner for tax purposes); and (4) the Contract’s AnnuityDate is not unduly delayed.

Diversification Requirements. The Code andTreasury Department regulations prescribe the mannerin which the investments of a segregated asset account,such as the Variable Account, are to be “adequatelydiversified.” If the Variable Account fails to comply withthese rules, the Contract will not be treated as anannuity Contract for federal income tax purposes, andso the interest or earnings credited to the Contract’sAccumulated Value in any year will be includible in theContract Owner’s income that year for federal taxpurposes. We expect that the Variable Account, throughthe Fund, will comply with these rules.

Ownership Treatment. In certain circumstances,variable annuity Contract Owners may be consideredthe owners, for federal income tax purposes, of theassets of a segregated asset account used to support theirContracts. In those circumstances, the account’s incomeand gains would be currently includible in the ContractOwners’ gross income. The Internal Revenue Service(the “IRS”) has stated in published rulings that avariable Contract Owner will be considered the ownerof the assets of a segregated asset account if the ownerpossesses incidents of ownership in those assets, such asthe ability to exercise investment control over theassets.

The ownership rights under the Contract are similar to,but different in certain respects from, the ownershiprights described in IRS rulings in which the ContractOwners were determined not to be the owners of theassets of a segregated asset account. For example, theContract Owner has the choice of more investmentoptions to which to allocate premium payments andthe Accumulated Value than were addressed in thoserulings. These differences could result in the ContractOwner being treated as the owner of all or a portion ofthe assets of the Variable Account and thus subject to

Page 43: THRIVENT FLEXIBLE PREMIUM DEFERRED VARIABLE ANNUITY · 2020-04-30 · THRIVENT VARIABLE ANNUITY ACCOUNT C THRIVENT SERIES FUND,INC. PROSPECTUS FOR FLEXIBLE PREMIUM DEFERRED VARIABLE

current taxation on the income and gains from thoseassets. In addition, we do not know what standards willbe set forth in any further regulations or rulings whichthe Treasury Department or the IRS may issue. Wetherefore reserve the right to modify the Contract asnecessary to attempt to prevent Contract Owners frombeing considered the owners of the assets of the VariableAccount. However, there is no assurance that suchefforts would be successful.

Contracts Not Owned by Individuals. As a generalrule, Contracts held by “nonnatural persons” such as acorporation, trust, or other similar entity are not treatedas annuity Contracts for federal tax purposes. Theincome on such Contracts (as defined in the tax law) istaxed as ordinary income that is received or accrued bythe Contract Owner during the taxable year. However,this rule generally will not apply to a Contract held by atrust or other entity which holds the Contract as anagent for a natural person. In addition, this rule will notapply to: (1) a Contract acquired by the estate of adecedent by reason of the death of the decedent; (2)Contracts used in connection with certain QualifiedPlans; (3) Contracts purchased by employers upon thetermination of certain Qualified Plans; (4) certainContracts used in connection with structured settlementagreements; and (5) a Contract purchased with a singlepremium payment when the annuity starting date is nolater than one year from the purchase of the Contractand substantially equal periodic payments are made,not less frequently than annually, during the annuityincome period.

The remainder of this discussion assumes that theContract will be treated as an annuity contract forfederal income tax purposes.

Taxation of Partial and Full Surrenders

In the case of a partial surrender, the amount received isgenerally includible in income for federal tax purposesto the extent that the Accumulated Value of theContract, before the partial surrender, exceeds the“investment in the Contract.” In the case of a fullsurrender, the amount received is includible in incometo the extent that it exceeds the investment in theContract. For these purposes, the investment in theContract at any time equals the total of the premiumpayments made under the Contract up to that time less

any amounts previously received from the Contractwhich were excludable from income. All amountsincludible in income with respect to the Contract aretaxed as ordinary income; no amounts are taxed at thelower rates currently applicable to long-term capitalgains and corporate dividends.

Taxation of Annuity Income Payments

Normally, the portion of each annuity income paymentincludible in income for federal tax purposes is theexcess of the payment over an exclusion amount. In thecase of variable income payments, this exclusionamount is the investment in the Contract (definedabove) allocated to the Variable Account whenpayments begin, adjusted for any period certain orrefund feature, divided by the number of paymentsexpected. In the case of fixed income payments, theexclusion amount is determined by multiplying (1) thepayment, by (2) the ratio of the investment in theContract allocated to our Fixed Account, adjusted forany period certain or refund feature, to the totalexpected amount of annuity income payments. For thispurpose, the expected number or amount of annuityincome payments is determined by TreasuryDepartment regulations which take into account theAnnuitant’s life expectancy and the form of annuitybenefit selected.

Once the total amount of the investment in theContract is excluded using the above formulas, annuityincome payments will be fully taxable. If annuityincome payments cease because of the death of theAnnuitant and before the total amount of theinvestment in the Contract is recovered, theunrecovered amount generally will be allowed as adeduction.

Income from annuities will be subject to the MedicareTax on Investment Income. This tax will be imposed onindividuals with a modified adjusted gross income(MAGI) of more than $200,000 and joint filers with anMAGI of more than $250,000. Generally, the tax ratewill be 3.8% of the lesser of the net investment incomeor the amount the MAGI exceeds the threshold amount.

There may be special income tax issues present insituations where the Contract Owner and the Annuitantare not the same person and are not married to oneanother. In such situations a tax advisor should beconsulted.

Tax Treatment of Death Benefit

Prior to the Annuity Date, we may distribute amountsfrom a Contract because of the death of a ContractOwner or, in certain circumstances, the death of theAnnuitant. If distributed in a lump sum, such deathbenefit proceeds are includible in income in the samemanner as a full surrender, or if distributed under anannuity income option, such proceeds are includible inthe same manner as annuity income payments.

After the Annuity Date, where a guaranteed periodexists under a life income option and the Annuitantdies before the end of that period, payments made tothe beneficiary for the remainder of that period areincludible in income as follows: (1) if received in a lumpsum, the payment is includible to the extent that itexceeds the unrecovered investment in the Contract; or(2) if distributed in accordance with the existingannuity income option, they are fully excluded fromincome until the remaining investment in the Contractis deemed to be recovered, and all payments thereafterare fully includible in income.

Assignments, Pledges, and Gratuitous Transfers

Any assignment or pledge of (or agreement to assign orpledge) any portion of the Accumulated Value of theContract is treated for federal income tax purposes as asurrender of such amount or portion. The investment inthe Contract is increased by the amount includible inincome with respect to such an assignment or pledge. Ifa Contract Owner transfers a Contract without adequateconsideration to a person other than the ContractOwner’s Spouse (or a former Spouse incident to divorce),the Contract Owner must include in income thedifference between the Contract’s Accumulated Valueand the investment in the Contract at the time of thetransfer. In such a case, the transferee’s investment inthe Contract is increased to reflect the amountincludible in the transferor’s income.

Penalty Tax on Premature Distributions

Technically, the amount of any payment from theContract that is includible in income is subject to a 10%penalty tax. However, this penalty tax does not apply toany payment: (1) received on or after the ContractOwner attains age 591⁄2; (2) attributable to the ContractOwner becoming disabled (as defined in the tax law);(3) made on or after the death of the Contract Owneror, if the Contract Owner is not an individual, on orafter the death of the primary annuitant (as defined inthe tax law); (4) that is part of a series of substantiallyequal periodic payments, not less frequently thanannually, for the life or life expectancy of the ContractOwner or the joint lives or joint life expectancies of theContract Owner and a designated beneficiary (asdefined in the tax law).; or, (5) made under a Contractpurchased with a single premium payment when theannuity starting date is no later than one year from thepurchase of the Contract and substantially equalperiodic payments are made, not less frequently thanannually, during the annuity period. For the purposes ofsubstantially equal periodic payments, if there is asignificant modification of the payment schedule beforethe later of the taxpayer reaching age 591⁄2 or theexpiration of five years from the time the paymentstarts, the taxpayer’s income shall be increased by theamount of tax and deferred interest that otherwisewould have been incurred.

Aggregation of Contracts

In certain circumstances, the IRS may determine theamount of any distribution from the Contract that isincludible in income by combining some or all of theannuity contracts a person owns. For example, if aperson purchases a contract and also purchases atapproximately the same time another deferred annuityissued by us, the IRS may treat the two contracts as onecontract. Similarly, if a person transfers part of his or herinterest in one annuity contract to purchase anotherannuity contract, the IRS might treat the two contractsas one contract. In addition, if a person purchases twoor more contracts from us (or an affiliate) during anycalendar year, all such contracts will be treated as onecontract for purposes of determining the amount of anyfull or partial surrender that is includible in income. Theeffects of such aggregation are not always clear;however, such aggregation could affect the amount of a

surrender or an annuity payment that is taxable and theamount which might be subject to the 10% penalty taxdescribed above.

Exchanges of Annuity Contracts

We may issue the Contract in exchange for all or part ofanother annuity contract. Such an exchange will beincome tax free if certain requirements are satisfied (a1035 Exchange). If the exchange is tax free, theinvestment in the Contract immediately after theexchange will generally be the same as that of theannuity contract exchanged, increased by anyadditional premium payment made as part of theexchange. If part of an existing contract is exchangedfor the Contract, the IRS might treat the two contractsas one annuity contract in certain circumstances. (See“Aggregation of Contracts.”) You should consult your taxadvisor in connection with an exchange of all or part ofan annuity contract for the Contract.

Qualified Plans

The Contracts also are designed for use with severaltypes of Qualified Plans. When used in Qualified Plans,deferred annuities like the Contracts do not offeradditional tax-deferral benefits, but annuities offer otherproduct benefits to investors in Qualified Plans.Participants under such Qualified Plans as well asContract Owners, Annuitants, and beneficiaries arecautioned that the rights of any person to any benefitsunder such Qualified Plans may be subject to the termsand conditions of the plans themselves regardless of theterms and conditions of the Contracts issued inconnection with them. Those who intend to use theContract in connection with Qualified Plans shouldseek competent advice.

The tax rules applicable to Qualified Plans, and to aContract when used in connection with a QualifiedPlan, vary according to the type of plan and the termsand conditions of the plan itself, and they takeprecedence over the general annuity tax rules describedabove. For example, for full surrenders, partialsurrenders, and annuity income payments underContracts used in Qualified Plans, there may be no“investment in the contract,” with the result that thetotal amount received may be includible in income. Theincludible amount is taxed at ordinary income tax rates,

and a 10% penalty tax also may apply. Exceptions tothis penalty tax vary depending on the type of QualifiedPlan involved; in the case of an Individual RetirementAnnuity (discussed below), exceptions comparable tothose described above are available.

The following briefly describes certain types of QualifiedPlans in connection with which we may issue aContract.

Traditional IRAs. Section 408 of the Code permitseligible individuals to contribute to an IndividualRetirement Account or an Individual RetirementAnnuity (collectively known as an “IRA”). IRAs aresubject to limits on the amounts that may becontributed and deducted, on the persons who may beeligible to do so, and on the time when distributionsmay commence. Also, subject to certain requirementsdiscussed below, you may “roll over” distributions fromcertain Qualified Plans on a tax-deferred basis into anIRA.

Roth IRAs. Section 408A of the Code permits eligibleindividuals to contribute to a type of IRA known as a“Roth IRA.” Roth IRAs are generally subject to the samerules as non-Roth IRAs, but differ in several respects.Among the differences is that, although contributionsto a Roth IRA are not deductible, “qualifieddistributions” (those that satisfy certain waiting and userequirements) from a Roth IRA will be excludable fromincome. Subject to certain restrictions, a distributionfrom an eligible employer-sponsored qualified plan maybe directly moved to a Roth IRA. This movement iscalled a “qualified rollover contribution.”

Section 403(b) Plans. Section 403(b) of the Codepermits public school employees and employees ofcertain types of charitable, educational, and scientificorganizations to have their employers purchase annuityContracts for them and, subject to certain limitations,to exclude the amount of premium payments fromincome for federal tax purposes. Subject to planprovisions, distributions from a Contract purchasedunder section 403(b) may be paid only when theemployee reaches age 591⁄2, separates from service, dies,or becomes disabled, the 403(b) plan terminates, or inthe case of financial hardship. As a result, the ContractOwner will not be entitled to exercise the surrender

rights described under the heading “The Contract—Surrender” unless one of the above conditions issatisfied. For contracts maintained pursuant to anemployer sponsored 403(b) plan, we may require theemployer’s signature to process any requests forwithdrawal, surrender, rollover or transfers to anothercontract.

Direct Rollovers

If your Contract is purchased under section 403(b) ofthe Code or is used in connection with certain otherQualified Plans, any “eligible rollover distribution” fromthe Contract will be subject to direct rollover andmandatory withholding requirements. An eligiblerollover distribution generally is any taxabledistribution from certain Qualified Plans (includingfrom a Contract purchased under section 403(b))excluding amounts such as minimum distributionsrequired under the Code. Under these requirements,federal income tax equal to 20% of the eligible rolloverdistribution will be withheld from the amount of thedistribution. Unlike withholding on certain otheramounts distributed from the Contract, discussed below,the Contract Contract Owner cannot elect out ofwithholding with respect to an eligible rollover

distribution. However, this 20% withholding will notapply if the distribution is directly rolled over to an IRAor to another eligible retirement plan.

Federal Income Tax Withholding

We will withhold and remit to the federal government apart of the taxable portion of each distribution madeunder a Contract unless the payee notifies us at orbefore the time of the distribution that he or she electsnot to have any amounts withheld. In certaincircumstances, we may be required to withhold tax. Thewithholding rates applicable to the taxable portion ofannuity income payments (other than eligible rolloverdistributions made in connection with Qualified Plans)are the same as the withholding rates generallyapplicable to payments of wages. Further, a 10%withholding rate applies to the taxable portion ofnon-periodic payments (including partial and fullsurrenders), and as discussed above, the withholdingrate applicable to eligible rollover distributions is 20%.Whether or not federal income tax is withheld, theContract Owner (or other applicable taxpayer) remainsliable for payment of federal income tax on Contractdistributions.

Total Annual Portfolio Operating Expenses 0.93%

Less Fee Waivers and/or ExpenseReimbursements1 0.17%

Total Annual Portfolio Operating Expenses AfterFee Waivers and/or Expense Reimbursements 0.76%

1 The Adviser has contractually agreed, for as long as the current feestructure is in place and through at least April 30, 2021, to waive anamount equal to any management fees indirectly incurred by thePortfolio as a result of its investment in any other mutual fund forwhich the Adviser or an affiliate serves as investment adviser, otherthan Thrivent Cash Management Trust. This contractual provisionmay be terminated upon the mutual agreement between theIndependent Directors of the Portfolio and the Adviser.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods. Inaddition, the example for the 1 Year period reflects theeffect of the contractual fee waiver and/or expense

reimbursement. The example also assumes that yourinvestment has a 5% return each year, and that thePortfolio’s operating expenses remain the same.Although your actual cost may be higher or lower, basedon the foregoing assumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent AggressiveAllocation Portfolio $78 $279 $498 $1,127

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 60% ofthe average value of its portfolio.

Principal StrategiesThe Portfolio pursues its objective by investing in acombination of other funds managed by the Adviser oran affiliate and directly held financial instruments. ThePortfolio is designed for investors who seek greaterlong-term capital growth and are comfortable withhigher levels of risk and volatility. The Portfolio uses aprescribed asset allocation strategy involving a two-stepprocess that is designed to achieve its desired risktolerance. The first step is the construction of a modelfor the allocation of the Portfolio’s assets across broadasset categories (namely, equity securities and debtsecurities). The second step involves the determinationof sub-classes within the broad asset categories andtarget weightings (i.e., what the Adviser determines isthe strategic allocation) for these sub-classes. Sub-classesfor equity securities may be based on marketcapitalization, investment style (such as growth orvalue), or economic sector. Sub-classes for debt securitiesmay be based on maturity, duration, security type orcredit rating (high yield—commonly known as “junkbonds”—or investment grade).

The use of target weightings for various sub-classeswithin broad asset categories is intended as a multi-styleapproach to reduce the risk of investing in securitieshaving common characteristics. The Portfolio may buyand sell futures contracts to either hedge its exposure orobtain exposure to certain investments.

The Portfolio may invest in foreign securities, includingthose of issuers in emerging markets. An “emergingmarket” country is any country determined by the

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. Therefore, a principal risk of investing in thePortfolio is that the allocation strategies used and theallocation decisions made will not produce the desiredresults.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Small Cap Risk. Smaller, less seasoned companiesoften have greater price volatility, lower trading volume,and less liquidity than larger, more establishedcompanies. These companies tend to have smallrevenues, narrower product lines, less managementdepth and experience, small shares of their product orservice markets, fewer financial resources, and lesscompetitive strength than larger companies. Suchcompanies seldom pay significant dividends that couldsoften the impact of a falling market on returns.

Mid Cap Risk. Medium-sized companies often havegreater price volatility, lower trading volume, and lessliquidity than larger, more-established companies. Thesecompanies tend to have smaller revenues, narrowerproduct lines, less management depth and experience,smaller shares of their product or service markets, fewerfinancial resources, and less competitive strength thanlarger companies.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Other Funds Risk. Because the Portfolio invests inother funds managed by the Adviser or an affiliate(“Other Funds”), the performance of the Portfolio isdependent, in part, upon the performance of OtherFunds in which the Portfolio may invest. As a result, thePortfolio is subject to the same risks as those faced bythe Other Funds. In addition, Other Funds may besubject to additional fees and expenses that will beborne by the Portfolio.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

Value Investing Risk. Value style investing includesthe risk that stocks of undervalued companies may notrise as quickly as anticipated if the market doesn’trecognize their intrinsic value or if value stocks are outof favor.

Foreign Securities Risk. Foreign securities generallycarry more risk and are more volatile than theirdomestic counterparts, in part because of potential forhigher political and economic risks, lack of reliableinformation and fluctuations in currency exchange rateswhere investments are denominated in currencies otherthan the U.S. dollar. Certain events in foreign marketsmay adversely affect foreign and domestic issuers,including interruptions in the global supply chain,natural disasters and outbreak of infectious diseases. ThePortfolio’s investment in any country could be subjectto governmental actions such as capital or currencycontrols, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome. Foreign securities may also be more difficult toresell than comparable U.S. securities because themarkets for foreign securities are often less liquid. Evenwhen a foreign security increases in price in its localcurrency, the appreciation may be diluted by adversechanges in exchange rates when the security’s value isconverted to U.S. dollars. Foreign withholding taxes alsomay apply and errors and delays may occur in thesettlement process for foreign securities.

Emerging Markets Risk. The economic and politicalstructures of developing countries in emerging markets,in most cases, do not compare favorably with the U.S.or other developed countries in terms of wealth andstability, and their financial markets often lack liquidity.Portfolio performance will likely be negatively affectedby portfolio exposure to countries and corporationsdomiciled in or with revenue exposures to countries inthe midst of, among other things, hyperinflation,currency devaluation, trade disagreements, suddenpolitical upheaval, or interventionist governmentpolicies. Portfolio performance may also be negativelyaffected by portfolio exposure to countries andcorporations domiciled in or with revenue exposures tocountries with less developed legal, tax, regulatory, andaccounting systems. Significant buying or selling actionsby a few major investors may also heighten thevolatility of emerging markets. These factors makeinvesting in emerging market countries significantlyriskier than in other countries, and events in any onecountry could cause the Portfolio’s share price todecline.

Foreign Currency Risk. The value of a foreigncurrency may decline against the U.S. dollar, whichwould reduce the dollar value of securities denominatedin that currency. The overall impact of such a decline offoreign currency can be significant, unpredictable, andlong lasting, depending on the currencies represented,how each one appreciates or depreciates in relation tothe U.S. dollar, and whether currency positions arehedged. Under normal conditions, the Portfolio doesnot engage in extensive foreign currency hedgingprograms. Further, exchange rate movements arevolatile, and it is not possible to effectively hedge thecurrency risks of many developing countries.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets. There is also no guarantee thatthe Adviser will be able to effectively implement thePortfolio’s investment objective.

Conflicts of Interest Risk. An investment in thePortfolio will be subject to a number of actual orpotential conflicts of interest.For example, the Adviseror its affiliates may provide services to the Portfolio forwhich the Portfolio would compensate the Adviserand/or such affiliates. The Portfolio may invest in otherpooled investment vehicles sponsored, managed, orotherwise affiliated with the Adviser, including otherPortfolios. The Adviser may have an incentive (financialor otherwise) to enter into transactions or arrangementson behalf of the Portfolio with itself or its affiliates in

circumstances where it might not have done sootherwise.

The Adviser or its affiliates manage other investmentfunds and/or accounts (including proprietary accounts)and have other clients with investment objectives andstrategies that are similar to, or overlap with, theinvestment objective and strategy of the Portfolio,creating conflicts of interest in investment andallocation decisions regarding the allocation ofinvestments that could be appropriate for the Portfolioand other clients of the Adviser or their affiliates.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Quantitative Investing Risk. Quantitative InvestingRisk is the risk that securities selected according to aquantitative analysis methodology can performdifferently from the market as a whole based on themodel and the factors used in the analysis, the weightplaced on each factor and changes in the factor’shistorical trends. Such models are based on assumptionsof these and other market factors, and the models maynot take into account certain factors, or perform asintended, and may result in a decline in the value of thePortfolio’s portfolio.

Derivatives Risk. The use of derivatives (such asfutures) involves additional risks and transaction costswhich could leave the Portfolio in a worse position thanif it had not used these instruments. The Portfolioutilizes equity futures in order to increase or decrease itsexposure to various asset classes at a lower cost thantrading stocks directly. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is the riskthat the other party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and may

exacerbate other types of risks, negatively impacting thevalue of the Portfolio.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared tobroad-based securities market indices. The indexdescriptions appear in the �Index Descriptions� sectionof the prospectus. Call 800-847-4836 or visitThrivent.com for performance results current to themost recent month-end.

The bar chart and table include the effects of Portfolioexpenses, but not charges or deductions against yourvariable contract, and assume that you sold yourinvestment at the end of the period. Because shares ofthe Portfolio are offered through variable life insuranceand variable annuity contracts, you should carefullyreview the variable contract prospectus for informationon applicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

How a Portfolio has performed in the past is notnecessarily an indication of how it will perform in thefuture. Performance information provides someindication of the risks of investing in the Portfolio byshowing changes in the Portfolio’s performance overtime.

1 Year 3 Years 5 Years 10 Years

Thrivent All CapPortfolio $73 $227 $395 $883

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 128% ofthe average value of its portfolio.

Principal StrategiesThe Portfolio’s principal strategy for achieving itsobjective is normally to invest the Portfolio’s assetsprimarily in common stocks of companies of anymarket capitalization.

The Portfolio’s Adviser is not constrained by anyparticular investment style. At any given time, theAdviser may tend to buy “growth” stocks or “value”stocks, or a combination of both types.

The Portfolio seeks to achieve its objective by investingin common stocks. The Adviser uses fundamental,quantitative, and technical investment researchtechniques and includes stocks of companies that itbelieves have demonstrated and will sustain aboveaverage earnings growth in the future when comparedto the economy and the stock market as a whole. Inaddition, the Portfolio may invest in companies that itbelieves are undervalued in relation to their longtermearnings power or asset value.

Issuers of potential investments are analyzed usingfundamental factors such as growth potential, earningsestimates, and financial condition. The Portfolio maysell securities for a variety of reasons, such as to securegains, limit losses, or reposition assets into morepromising opportunities.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets in

companies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

Value Investing Risk. Value style investing includesthe risk that stocks of undervalued companies may notrise as quickly as anticipated if the market doesn’trecognize their intrinsic value or if value stocks are outof favor.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser orsubadviser in assessing the potential of the investmentsin which the Portfolio invests. This assessment ofinvestments may prove incorrect, resulting in losses orpoor performance, even in rising markets. There is alsono guarantee that the Adviser will be able to effectivelyimplement the Portfolio’s investment objective.

Mid Cap Risk. Medium-sized companies often havegreater price volatility, lower trading volume, and lessliquidity than larger, more-established companies. Thesecompanies tend to have smaller revenues, narrowerproduct lines, less management depth and experience,smaller shares of their product or service markets, fewerfinancial resources, and less competitive strength thanlarger companies.

Small Cap Risk. Smaller, less seasoned companiesoften have greater price volatility, lower trading volume,and less liquidity than larger, more establishedcompanies. These companies tend to have smallrevenues, narrower product lines, less managementdepth and experience, small shares of their product orservice markets, fewer financial resources, and lesscompetitive strength than larger companies. Suchcompanies seldom pay significant dividends that couldsoften the impact of a falling market on returns.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five-, and ten-year periods compared tobroad-based securities market indices.

The debt securities in which the Portfolio invests maybe of any maturity or credit quality, including highyield, high risk bonds, notes, debentures and other debtobligations commonly known as “junk bonds.” At thetime of purchase, these high-yield securities are ratedwithin or below the “BB” major rating category by S&Por the “Ba” major rating category by Moody’s or areunrated but considered to be of comparable quality bythe Adviser.

The Portfolio utilizes derivatives primarily in the formof U.S. Treasury futures contracts in order to manage thePortfolio’s duration, or interest rate risk. The Portfoliomay enter into derivatives contracts traded onexchanges or in the over the counter market.

The Portfolio may also pursue its investment strategy byinvesting in other mutual funds managed by theAdviser or an affiliate.

The Adviser uses fundamental, quantitative andtechnical investment research techniques to determinewhat to buy and sell. Fundamental techniques assess asecurity’s value based on an issuer’s financial profile,management, and business prospects while quantitativeand technical techniques involve a more data-orientedanalysis of financial information, market trends andprice movements.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Changes by the Federal Reserve tomonetary policies could affect interest rates and thevalue of some securities. In addition, the phase out ofLIBOR (the offered rate for short-term Eurodollardeposits between major international banks) by the endof 2021 could lead to increased volatility and illiquidityin certain markets that currently rely on LIBOR todetermine interest rates.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may no

longer be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. Therefore, a principal risk of investing in thePortfolio is that the allocation strategies used and theallocation decisions made will not produce the desiredresults.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Prepayment Risk. When interest rates fall, certainobligations will be paid off by the obligor more quicklythan originally anticipated, and a Portfolio may have toinvest the proceeds in securities with lower yields. In

Page 68: THRIVENT FLEXIBLE PREMIUM DEFERRED VARIABLE ANNUITY · 2020-04-30 · THRIVENT VARIABLE ANNUITY ACCOUNT C THRIVENT SERIES FUND,INC. PROSPECTUS FOR FLEXIBLE PREMIUM DEFERRED VARIABLE

periods of falling interest rates, the rate of prepaymentstends to increase (as does price fluctuation) as borrowersare motivated to pay off debt and refinance at newlower rates. During such periods, reinvestment of theprepayment proceeds by the management team willgenerally be at lower rates of return than the return onthe assets that were prepaid. Prepayment generallyreduces the yield to maturity and the average life of thesecurity.

Foreign Securities Risk. Foreign securities generallycarry more risk and are more volatile than theirdomestic counterparts, in part because of potential forhigher political and economic risks, lack of reliableinformation and fluctuations in currency exchange rateswhere investments are denominated in currencies otherthan the U.S. dollar. Certain events in foreign marketsmay adversely affect foreign and domestic issuers,including interruptions in the global supply chain,natural disasters and outbreak of infectious diseases. ThePortfolio’s investment in any country could be subjectto governmental actions such as capital or currencycontrols, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome. Foreign securities may also be more difficult toresell than comparable U.S. securities because themarkets for foreign securities are often less liquid. Evenwhen a foreign security increases in price in its localcurrency, the appreciation may be diluted by adversechanges in exchange rates when the security’s value isconverted to U.S. dollars. Foreign withholding taxes alsomay apply and errors and delays may occur in thesettlement process for foreign securities.

Emerging Markets Risk. The economic and politicalstructures of developing countries in emerging markets,in most cases, do not compare favorably with the U.S.or other developed countries in terms of wealth andstability, and their financial markets often lack liquidity.Portfolio performance will likely be negatively affectedby portfolio exposure to countries and corporationsdomiciled in or with revenue exposures to countries inthe midst of, among other things, hyperinflation,currency devaluation, trade disagreements, suddenpolitical upheaval, or interventionist governmentpolicies. Portfolio performance may also be negativelyaffected by portfolio exposure to countries andcorporations domiciled in or with revenue exposures tocountries with less developed legal, tax, regulatory, andaccounting systems. Significant buying or selling actionsby a few major investors may also heighten thevolatility of emerging markets. These factors makeinvesting in emerging market countries significantlyriskier than in other countries, and events in any onecountry could cause the Portfolio’s share price todecline.

Foreign Currency Risk. The value of a foreigncurrency may decline against the U.S. dollar, whichwould reduce the dollar value of securities denominatedin that currency. The overall impact of such a decline offoreign currency can be significant, unpredictable, andlong lasting, depending on the currencies represented,how each one appreciates or depreciates in relation tothe U.S. dollar, and whether currency positions arehedged. Under normal conditions, the Portfolio doesnot engage in extensive foreign currency hedgingprograms. Further, exchange rate movements arevolatile, and it is not possible to effectively hedge thecurrency risks of many developing countries.

Mortgage-Backed and Other Asset-BackedSecurities Risk. The value of mortgage-backed andasset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlyingsuch securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid. In addition, bothmortgage-backed and asset-backed securities aresensitive to changes in the repayment patterns of theunderlying security. If the principal payment on theunderlying asset is repaid faster or slower than theholder of the asset-backed or mortgage-backed securityanticipates, the price of the security may fall,particularly if the holder must reinvest the repaidprincipal at lower rates or must continue to hold thesecurity when interest rates rise. This effect may causethe value of the Portfolio to decline and reduce theoverall return of the Portfolio.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected. High yield securities generally have a lessliquid resale market.

Sovereign Debt Risk. Sovereign debt securities areissued or guaranteed by foreign governmental entities.These investments are subject to the risk that agovernmental entity may delay or refuse to pay interestor repay principal on its sovereign debt, due, forexample, to cash flow problems, insufficient foreigncurrency reserves, political considerations, the relativesize of the governmental entity’s debt position inrelation to the economy or the failure to put in placeeconomic reforms required by the InternationalMonetary Fund or other multilateral agencies. If agovernmental entity defaults, it may ask for more timein which to pay or for further loans. There is no legal

process for collecting sovereign debts that a governmentdoes not pay nor are there bankruptcy proceedingsthrough which all or part of the sovereign debt that agovernmental entity has not repaid may be collected.

Quantitative Investing Risk. Quantitative InvestingRisk is the risk that securities selected according to aquantitative analysis methodology can performdifferently from the market as a whole based on themodel and the factors used in the analysis, the weightplaced on each factor and changes in the factor’shistorical trends. Such models are based on assumptionsof these and other market factors, and the models maynot take into account certain factors, or perform asintended, and may result in a decline in the value of thePortfolio’s portfolio.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets. There is also no guarantee thatthe Adviser will be able to effectively implement thePortfolio’s investment objective.

Conflicts of Interest Risk. An investment in thePortfolio will be subject to a number of actual orpotential conflicts of interest.For example, the Adviseror its affiliates may provide services to the Portfolio forwhich the Portfolio would compensate the Adviserand/or such affiliates. The Portfolio may invest in otherpooled investment vehicles sponsored, managed, orotherwise affiliated with the Adviser, including otherPortfolios. The Adviser may have an incentive (financialor otherwise) to enter into transactions or arrangementson behalf of the Portfolio with itself or its affiliates incircumstances where it might not have done sootherwise.

The Adviser or its affiliates manage other investmentfunds and/or accounts (including proprietary accounts)and have other clients with investment objectives andstrategies that are similar to, or overlap with, theinvestment objective and strategy of the Portfolio,creating conflicts of interest in investment andallocation decisions regarding the allocation ofinvestments that could be appropriate for the Portfolioand other clients of the Adviser or their affiliates.

Other Funds Risk. Because the Portfolio invests inother funds managed by the Adviser or an affiliate(“Other Funds”), the performance of the Portfolio isdependent, in part, upon the performance of OtherFunds in which the Portfolio may invest. As a result, thePortfolio is subject to the same risks as those faced bythe Other Funds. In addition, Other Funds may besubject to additional fees and expenses that will beborne by the Portfolio.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures) involves additional risks and transaction costswhich could leave the Portfolio in a worse position thanif it had not used these instruments. The Portfolioutilizes futures on U.S. Treasuries in order to manageduration. The use of derivatives can lead to lossesbecause of adverse movements in the price or value ofthe underlying asset, index or rate, which may bemagnified by certain features of the contract. Changesin the value of the derivative may not correlate asintended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is the riskthat the other party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Dealer inventories ofbonds are at or near historic lows in relation to marketsize, which has the potential to decrease liquidity andincrease price volatility in the fixed income markets,particularly during periods of economic or market stress.As a result of this decreased liquidity, the Portfolio mayhave to accept a lower price to sell a security, sell othersecurities to raise cash, or give up an investmentopportunity, any of which could have a negative effecton performance.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

The equity securities in which the Portfolio invests mayinclude common stock, preferred stock, securitiesconvertible into common stock, or securities or otherinstruments the price of which is linked to the value ofcommon stock.

The debt securities in which the Portfolio invests maybe of any maturity or credit quality, including highyield, high risk bonds, notes, debentures and other debtobligations commonly known as “junk bonds.” At thetime of purchase, these high-yield securities are ratedwithin or below the “BB” major rating category by S&Por the “Ba” major rating category by Moody’s or areunrated but considered to be of comparable quality bythe Adviser. The Portfolio may also invest in leveragedloans, which are senior secured loans that are made bybanks or other lending institutions to companies thatare rated below investment grade.

The Portfolio utilizes derivatives primarily in the formof U.S. Treasury futures contracts in order to manage thePortfolio’s duration, or interest rate risk. The Portfoliomay enter into derivatives contracts traded onexchanges or in the over the counter market.

The Portfolio may also pursue its investment strategy byinvesting in other mutual funds managed by theAdviser or an affiliate.

The Adviser uses fundamental, quantitative andtechnical investment research techniques to determinewhat to buy and sell. Fundamental techniques assess asecurity’s value based on an issuer’s financial profile,management, and business prospects while quantitativeand technical techniques involve a more data-orientedanalysis of financial information, market trends andprice movements.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Changes by the Federal Reserve tomonetary policies could affect interest rates and thevalue of some securities. In addition, the phase out ofLIBOR (the offered rate for short-term Eurodollardeposits between major international banks) by the endof 2021 could lead to increased volatility and illiquidityin certain markets that currently rely on LIBOR todetermine interest rates.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may no

longer be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. Therefore, a principal risk of investing in thePortfolio is that the allocation strategies used and theallocation decisions made will not produce the desiredresults.

Mortgage-Backed and Other Asset-BackedSecurities Risk. The value of mortgage-backed andasset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlyingsuch securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid. In addition, bothmortgage-backed and asset-backed securities aresensitive to changes in the repayment patterns of theunderlying security. If the principal payment on theunderlying asset is repaid faster or slower than theholder of the asset-backed or mortgage-backed securityanticipates, the price of the security may fall,particularly if the holder must reinvest the repaidprincipal at lower rates or must continue to hold thesecurity when interest rates rise. This effect may causethe value of the Portfolio to decline and reduce theoverall return of the Portfolio.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected. High yield securities generally have a lessliquid resale market.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associated

TSF-20

Page 75: THRIVENT FLEXIBLE PREMIUM DEFERRED VARIABLE ANNUITY · 2020-04-30 · THRIVENT VARIABLE ANNUITY ACCOUNT C THRIVENT SERIES FUND,INC. PROSPECTUS FOR FLEXIBLE PREMIUM DEFERRED VARIABLE

with debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Prepayment Risk. When interest rates fall, certainobligations will be paid off by the obligor more quicklythan originally anticipated, and a Portfolio may have toinvest the proceeds in securities with lower yields. Inperiods of falling interest rates, the rate of prepaymentstends to increase (as does price fluctuation) as borrowersare motivated to pay off debt and refinance at newlower rates. During such periods, reinvestment of theprepayment proceeds by the management team willgenerally be at lower rates of return than the return onthe assets that were prepaid. Prepayment generallyreduces the yield to maturity and the average life of thesecurity.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Foreign Securities Risk. Foreign securities generallycarry more risk and are more volatile than theirdomestic counterparts, in part because of potential forhigher political and economic risks, lack of reliableinformation and fluctuations in currency exchange rateswhere investments are denominated in currencies otherthan the U.S. dollar. Certain events in foreign marketsmay adversely affect foreign and domestic issuers,including interruptions in the global supply chain,natural disasters and outbreak of infectious diseases. ThePortfolio’s investment in any country could be subjectto governmental actions such as capital or currencycontrols, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome. Foreign securities may also be more difficult to

resell than comparable U.S. securities because themarkets for foreign securities are often less liquid. Evenwhen a foreign security increases in price in its localcurrency, the appreciation may be diluted by adversechanges in exchange rates when the security’s value isconverted to U.S. dollars. Foreign withholding taxes alsomay apply and errors and delays may occur in thesettlement process for foreign securities.

Emerging Markets Risk. The economic and politicalstructures of developing countries in emerging markets,in most cases, do not compare favorably with the U.S.or other developed countries in terms of wealth andstability, and their financial markets often lack liquidity.Portfolio performance will likely be negatively affectedby portfolio exposure to countries and corporationsdomiciled in or with revenue exposures to countries inthe midst of, among other things, hyperinflation,currency devaluation, trade disagreements, suddenpolitical upheaval, or interventionist governmentpolicies. Portfolio performance may also be negativelyaffected by portfolio exposure to countries andcorporations domiciled in or with revenue exposures tocountries with less developed legal, tax, regulatory, andaccounting systems. Significant buying or selling actionsby a few major investors may also heighten thevolatility of emerging markets. These factors makeinvesting in emerging market countries significantlyriskier than in other countries, and events in any onecountry could cause the Portfolio’s share price todecline.

Foreign Currency Risk. The value of a foreigncurrency may decline against the U.S. dollar, whichwould reduce the dollar value of securities denominatedin that currency. The overall impact of such a decline offoreign currency can be significant, unpredictable, andlong lasting, depending on the currencies represented,how each one appreciates or depreciates in relation tothe U.S. dollar, and whether currency positions arehedged. Under normal conditions, the Portfolio doesnot engage in extensive foreign currency hedgingprograms. Further, exchange rate movements arevolatile, and it is not possible to effectively hedge thecurrency risks of many developing countries.

Preferred Securities Risk. There are certainadditional risks associated with investing in preferredsecurities, including, but not limited to, preferredsecurities may include provisions that permit the issuer,at its discretion, to defer or omit distributions for astated period without any adverse consequences to theissuer; preferred securities are generally subordinated tobonds and other debt instruments in a company’scapital structure in terms of having priority to corporateincome and liquidation payments, and therefore will besubject to greater credit risk than more senior debtinstruments; preferred securities may be substantiallyless liquid than many other securities, such as common

stocks or U.S. Government securities; generally,traditional preferred securities offer no voting rightswith respect to the issuing company unless preferreddividends have been in arrears for a specified number ofperiods, at which time the preferred security holdersmay elect a number of directors to the issuer’s board;and in certain varying circumstances, an issuer ofpreferred securities may redeem the securities prior to aspecified date.

Other Funds Risk. Because the Portfolio invests inother funds managed by the Adviser or an affiliate(“Other Funds”), the performance of the Portfolio isdependent, in part, upon the performance of OtherFunds in which the Portfolio may invest. As a result, thePortfolio is subject to the same risks as those faced bythe Other Funds. In addition, Other Funds may besubject to additional fees and expenses that will beborne by the Portfolio.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets. There is also no guarantee thatthe Adviser will be able to effectively implement thePortfolio’s investment objective.

Conflicts of Interest Risk. An investment in thePortfolio will be subject to a number of actual orpotential conflicts of interest.For example, the Adviseror its affiliates may provide services to the Portfolio forwhich the Portfolio would compensate the Adviserand/or such affiliates. The Portfolio may invest in otherpooled investment vehicles sponsored, managed, orotherwise affiliated with the Adviser, including otherPortfolios. The Adviser may have an incentive (financialor otherwise) to enter into transactions or arrangementson behalf of the Portfolio with itself or its affiliates incircumstances where it might not have done sootherwise.

The Adviser or its affiliates manage other investmentfunds and/or accounts (including proprietary accounts)and have other clients with investment objectives andstrategies that are similar to, or overlap with, theinvestment objective and strategy of the Portfolio,creating conflicts of interest in investment andallocation decisions regarding the allocation ofinvestments that could be appropriate for the Portfolioand other clients of the Adviser or their affiliates.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflects

the actual value of the security. Dealer inventories ofbonds are at or near historic lows in relation to marketsize, which has the potential to decrease liquidity andincrease price volatility in the fixed income markets,particularly during periods of economic or market stress.As a result of this decreased liquidity, the Portfolio mayhave to accept a lower price to sell a security, sell othersecurities to raise cash, or give up an investmentopportunity, any of which could have a negative effecton performance.

Derivatives Risk. The use of derivatives (such asfutures) involves additional risks and transaction costswhich could leave the Portfolio in a worse position thanif it had not used these instruments. The Portfolioutilizes futures on U.S. Treasuries in order to manageduration. The use of derivatives can lead to lossesbecause of adverse movements in the price or value ofthe underlying asset, index or rate, which may bemagnified by certain features of the contract. Changesin the value of the derivative may not correlate asintended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is the riskthat the other party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Quantitative Investing Risk. Quantitative InvestingRisk is the risk that securities selected according to aquantitative analysis methodology can performdifferently from the market as a whole based on themodel and the factors used in the analysis, the weightplaced on each factor and changes in the factor’shistorical trends. Such models are based on assumptionsof these and other market factors, and the models maynot take into account certain factors, or perform asintended, and may result in a decline in the value of thePortfolio’s portfolio.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the global

Thrivent ESG Index PortfolioInvestment ObjectiveThrivent ESG Index Portfolio (the �Portfolio�) seeks totrack the investment results of an index composed ofcompanies selected by the index provider based onenvironmental, social and governance characteristics.The Portfolio’s investment objective may be changedwithout shareholder approval.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a % of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the lower of the original purchaseprice or current net asset value) N/A

Management Fees 0.20%

Other Expenses1 2.78%

Total Annual Portfolio Operating Expenses 2.98%

Less Fee Waivers and/or ExpenseReimbursements2 2.60%

Total Annual Portfolio Operating Expenses AfterFee Waivers and/or Expense Reimbursements 0.38%

1 These expenses are based on estimated amounts for the currentfiscal year.

2 The Adviser has contractually agreed, through at least April 30,2021, to waive certain fees and/or reimburse certain expensesassociated with the shares of the Thrivent ESG Index Portfolio inorder to limit the Total Annual Portfolio Operating Expenses AfterFee Waivers and/or Expense Reimbursements to an annual rate of0.38% of the average daily net assets of the shares. This contractualprovision, however, may be terminated before the indicatedtermination date upon the mutual agreement between theIndependent Directors of the Portfolio and the Adviser.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in the

Portfolio for the time periods indicated and thenredeem all of your shares at the end of those periods. Inaddition, the example for the 1 Year period reflects theeffect of the contractual fee waiver and/or expensereimbursement. The example also assumes that yourinvestment has a 5% return each year, and that thePortfolio’s operating expenses remain the same.Although your actual cost may be higher or lower, basedon the foregoing assumptions, your cost would be:

1 Year 3 Years

Thrivent ESG Index Portfolio $39 $675

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. Because the Portfolio had notyet commenced operations prior to the date of thisprospectus, the Portfolio’s portfolio turnover rate for themost recent fiscal year end is not yet available.

Principal StrategiesUnder normal circumstances, the Portfolio investssubstantially all of its assets (more than 80% of its netassets, plus the amount of any borrowings forinvestment purposes) in the common stocks ofcompanies included in the MSCI KLD 400 Social Index(the “Index”) in the proportions in which they arerepresented in the Index. This is a passively managedPortfolio, which means that the Adviser does notactively choose the securities that should make up thePortfolio. The Index is a float-adjusted marketcapitalization weighted index designed to provideexposure to U.S. companies with outstandingenvironmental, social and governance (“ESG”) ratingsand excluding exposure to companies with negativesocial or environmental impacts, all as identified byMSCI Inc. (the “Index Provider” or “MSCI”). As ofMarch 31, 2020, the Index consisted of 404 companiesidentified by the Index Provider from the universe ofcompanies included in the MSCI USA IMI Index, whichtargets 99% of the market coverage of stocks that arelisted for trading on major exchanges in the U.S., asdetermined by the Index Provider. MSCI constructs theIndex based on considerations of ESG performance,sector alignment and size representation of each eligiblecompany, as described in more detail below. Themethodology MSCI uses to construct the Index is as ofthe date of this prospectus and is subject to change as

TSF-26

Page 81: THRIVENT FLEXIBLE PREMIUM DEFERRED VARIABLE ANNUITY · 2020-04-30 · THRIVENT VARIABLE ANNUITY ACCOUNT C THRIVENT SERIES FUND,INC. PROSPECTUS FOR FLEXIBLE PREMIUM DEFERRED VARIABLE

determined from time to time by MSCI. The Indexexcludes companies whose products have negativesocial or environmental impacts. Companies that MSCIdetermines have significant involvement in thefollowing businesses are not eligible for theIndex: alcohol, gambling, tobacco, military weapons,civilian firearms, nuclear power, adult entertainmentand genetically modified organisms.

In evaluating ESG performance of eligible companies,MSCI uses proprietary ratings and research covering ESGcriteria. MSCI identifies companies that demonstrate anability to manage their ESG risks and opportunities.MSCI identifies key ESG issues that hold the greatestpotential risk or opportunity for each industry sector,which may include the following: climate change,natural resources, pollution and waste, environmentalopportunities, human capital, product liability,stakeholder opposition, social opportunities, corporategovernance, and corporate behavior. MSCI calculates acompany’s exposure relating to a key issue based on ananalysis of a company’s business and takes into accounta company’s management process of that issue. MSCI’sESG criteria also includes, but is not limited to, ananalysis of companies involved in very seriouscontroversies, which may result in those companies’exclusion from the Index.

The Index is reviewed quarterly for adjustments, andwhen changes to the Index occur, the Adviser willattempt to replicate these changes within the Portfolio.However, any such changes may result in slightvariations from time to time. The Index may includelarge, mid or small cap companies. The components ofthe Index, and the degree to which these componentsrepresent certain industry sectors, are likely to changeover time. The Portfolio may buy and sell equity indexfutures and exchange traded funds (“ETF”) forinvestment exposure. For liquidity reasons, the Portfoliomay invest to some degree in money marketinstruments.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.ESG (Environmental, Social & Governance)Investment Strategy Risk. The Portfolio’s ESGinvestment strategy limits the types and number ofinvestment opportunities available to the Portfolio and,as a result, the Portfolio may underperform other fundsthat do not have an ESG focus. The Portfolio’s ESGinvestment strategy may result in the Portfolio investingin securities or industry sectors that underperform themarket as a whole or underperform other fundsscreened for ESG standards. In addition, the IndexProvider may be unsuccessful in creating an index

composed of companies that exhibit positive ESGcharacteristics.Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.ETF Risk. An ETF is subject to the risks of theunderlying investments that it holds. In addition, forindex-based ETFs, the performance of an ETF maydiverge from the performance of such index (commonlyknown as tracking error). ETFs are subject to fees andexpenses (like management fees and operatingexpenses) that do not apply to an index, and thePortfolio will indirectly bear its proportionate share ofany such fees and expenses paid by the ETFs in which itinvests. Because ETFs trade on an exchange, there is arisk that an ETF will trade at a discount to net assetvalue or that investors will fail to bring the trading pricein line with the underlying shares (known as thearbitrage mechanism).Futures Contract Risk. The value of a futurescontract tends to increase and decrease in tandem withthe value of the underlying instrument. The price offutures can be highly volatile; using them could lowertotal return, and the potential loss from futures canexceed the Portfolio’s initial investment in suchcontracts. In addition, the value of the futures contractmay not accurately track the value of the underlyinginstrument.Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.Mid Cap Risk. Medium-sized companies often havegreater price volatility, lower trading volume, and less

Page 82: THRIVENT FLEXIBLE PREMIUM DEFERRED VARIABLE ANNUITY · 2020-04-30 · THRIVENT VARIABLE ANNUITY ACCOUNT C THRIVENT SERIES FUND,INC. PROSPECTUS FOR FLEXIBLE PREMIUM DEFERRED VARIABLE

liquidity than larger, more-established companies. Thesecompanies tend to have smaller revenues, narrowerproduct lines, less management depth and experience,smaller shares of their product or service markets, fewerfinancial resources, and less competitive strength thanlarger companies.Sector Risk. Companies with similar characteristicsmay be grouped together in broad categories calledsectors. From time to time, the Portfolio may havesignificant positions in one or more sectors of themarket. To the extent the Portfolio invests more heavilyin particular sectors than others, its performance may bemore susceptible to developments that significantlyaffect those sectors. Individual sectors may be morevolatile, and may perform differently, than the broadermarket. The industries that constitute a sector may allreact in the same way to economic, political orregulatory events.Indexing Strategy/Index Tracking Risk. ThePortfolio is managed with an indexing investmentstrategy, attempting to track the performance of anunmanaged index of securities, regardless of the currentor projected performance of the Index or of the actualsecurities comprising the Index. The structure andcomposition of the Index will affect the performance,volatility, and risk of the Index and, consequently, theperformance, volatility, and risk of the Portfolio. Whilethe Adviser seeks to track the performance of the Index(i.e., achieve a high degree of correlation with theIndex), the Portfolio’s return may not match the returnof the Index. The Portfolio incurs a number of operatingexpenses not applicable to the Index, and incurs costs inbuying and selling securities. In addition, the Portfoliomay not be fully invested at times, generally as a resultof cash flows into or out of the Portfolio or reserves ofcash held by the Portfolio to meet redemptions. TheAdviser may attempt to replicate the Index return byinvesting in fewer than all of the securities in the Index,or in some securities not included in the Index,potentially increasing the risk of divergence between thePortfolio’s return and that of the Index.Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods.The example also assumes that your investment has a5% return each year, and that the Portfolio’s operatingexpenses remain the same. Although your actual costmay be higher or lower, based on the foregoingassumptions, your cost would be:

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turns

over” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 76% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets in equity securities and investsat least 40% of its net assets in foreign securities (undernormal market conditions). The Adviser focuses mainlyon the equity securities of domestic and internationalcompanies. Should the Adviser change the investmentsused for purposes of this 80% threshold, we will notifyyou at least 60 days prior to the change.

The Portfolio seeks to achieve its investment objectiveby investing primarily in domestic and foreign commonstocks. The Portfolio may buy and sell futures contractsto either hedge its exposure or obtain exposure tocertain investments. The Adviser uses fundamental,quantitative, and technical investment researchtechniques to determine what stocks to buy and sell.Fundamental techniques assess a security’s value basedon an issuer’s financial profile, management, andbusiness prospects while quantitative and technicaltechniques involve a more data-oriented analysis offinancial information, market trends and pricemovements. The Portfolio may sell securities for avariety of reasons, such as to secure gains, limit losses,or reposition assets into more promising opportunities.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Foreign Securities Risk. Foreign securities generallycarry more risk and are more volatile than theirdomestic counterparts, in part because of potential forhigher political and economic risks, lack of reliableinformation and fluctuations in currency exchange rateswhere investments are denominated in currencies otherthan the U.S. dollar. Certain events in foreign marketsmay adversely affect foreign and domestic issuers,including interruptions in the global supply chain,natural disasters and outbreak of infectious diseases. ThePortfolio’s investment in any country could be subjectto governmental actions such as capital or currencycontrols, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome. Foreign securities may also be more difficult toresell than comparable U.S. securities because themarkets for foreign securities are often less liquid. Evenwhen a foreign security increases in price in its localcurrency, the appreciation may be diluted by adversechanges in exchange rates when the security’s value isconverted to U.S. dollars. Foreign withholding taxes alsomay apply and errors and delays may occur in thesettlement process for foreign securities.

Foreign Currency Risk. The value of a foreigncurrency may decline against the U.S. dollar, whichwould reduce the dollar value of securities denominatedin that currency. The overall impact of such a decline offoreign currency can be significant, unpredictable, andlong lasting, depending on the currencies represented,how each one appreciates or depreciates in relation tothe U.S. dollar, and whether currency positions arehedged. Under normal conditions, the Portfolio doesnot engage in extensive foreign currency hedgingprograms. Further, exchange rate movements arevolatile, and it is not possible to effectively hedge thecurrency risks of many developing countries.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Quantitative Investing Risk. Quantitative InvestingRisk is the risk that securities selected according to a

quantitative analysis methodology can performdifferently from the market as a whole based on themodel and the factors used in the analysis, the weightplaced on each factor and changes in the factor’shistorical trends. Such models are based on assumptionsof these and other market factors, and the models maynot take into account certain factors, or perform asintended, and may result in a decline in the value of thePortfolio’s portfolio.

Mid Cap Risk. Medium-sized companies often havegreater price volatility, lower trading volume, and lessliquidity than larger, more-established companies. Thesecompanies tend to have smaller revenues, narrowerproduct lines, less management depth and experience,smaller shares of their product or service markets, fewerfinancial resources, and less competitive strength thanlarger companies.

Small Cap Risk. Smaller, less seasoned companiesoften have greater price volatility, lower trading volume,and less liquidity than larger, more establishedcompanies. These companies tend to have smallrevenues, narrower product lines, less managementdepth and experience, small shares of their product orservice markets, fewer financial resources, and lesscompetitive strength than larger companies. Suchcompanies seldom pay significant dividends that couldsoften the impact of a falling market on returns.

Emerging Markets Risk. The economic and politicalstructures of developing countries in emerging markets,in most cases, do not compare favorably with the U.S.or other developed countries in terms of wealth andstability, and their financial markets often lack liquidity.Portfolio performance will likely be negatively affectedby portfolio exposure to countries and corporationsdomiciled in or with revenue exposures to countries inthe midst of, among other things, hyperinflation,currency devaluation, trade disagreements, suddenpolitical upheaval, or interventionist governmentpolicies. Portfolio performance may also be negativelyaffected by portfolio exposure to countries andcorporations domiciled in or with revenue exposures tocountries with less developed legal, tax, regulatory, andaccounting systems. Significant buying or selling actionsby a few major investors may also heighten thevolatility of emerging markets. These factors makeinvesting in emerging market countries significantlyriskier than in other countries, and events in any onecountry could cause the Portfolio’s share price todecline.

Futures Contract Risk. The value of a futurescontract tends to increase and decrease in tandem withthe value of the underlying instrument. The price offutures can be highly volatile; using them could lowertotal return, and the potential loss from futures canexceed the Portfolio’s initial investment in suchcontracts. In addition, the value of the futures contract

Page 86: THRIVENT FLEXIBLE PREMIUM DEFERRED VARIABLE ANNUITY · 2020-04-30 · THRIVENT VARIABLE ANNUITY ACCOUNT C THRIVENT SERIES FUND,INC. PROSPECTUS FOR FLEXIBLE PREMIUM DEFERRED VARIABLE

may not accurately track the value of the underlyinginstrument.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets. There is also no guarantee thatthe Adviser will be able to effectively implement thePortfolio’s investment objective.

Derivatives Risk. The use of derivatives (such asfutures) involves additional risks and transaction costswhich could leave the Portfolio in a worse position thanif it had not used these instruments. The Portfolioutilizes equity futures in order to increase or decrease itsexposure to various asset classes at a lower cost thantrading stocks directly. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is the riskthat the other party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared toa broad-based securities market index. The indexdescription appears in the �Index Descriptions� sectionof the prospectus. Call 800-847-4836 or visit

Thrivent.com for performance results current to themost recent month-end.

The bar chart and table include the effects of Portfolioexpenses, but not charges or deductions against yourvariable contract, and assume that you sold yourinvestment at the end of the period. Because shares ofthe Portfolio are offered through variable life insuranceand variable annuity contracts, you should carefullyreview the variable contract prospectus for informationon applicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

How a Portfolio has performed in the past is notnecessarily an indication of how it will perform in thefuture. Performance information provides someindication of the risks of investing in the Portfolio byshowing changes in the Portfolio’s performance overtime.

1 Year 3 Years 5 Years 10 Years

Thrivent GovernmentBond Portfolio $47 $148 $258 $579

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 354% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount ofborrowings for investment purposes) in U.S.government bonds. For purposes of this disclosure, “U.S.government bonds” are debt instruments issued orguaranteed by the U.S. government or its agencies andinstrumentalities, including U.S. Treasuries, TreasuryInflation Protected Securities (TIPS), U.S. GovernmentAgency debt, and mortgage-backed securities issued orguaranteed by the Government National MortgageAssociation (GNMA or Ginnie Mae), the FederalNational Mortgage Association (FNMA or Fannie Mae)or the Federal Home Loan Mortgage Corporation(FHLMC or Freddie Mac). Should the Adviser change theinvestments used for purposes of this 80% threshold,you will be notified at least 60 days prior to the change.

The Portfolio’s portfolio securities may be of anymaturity. The Adviser uses fundamental, quantitativeand technical investment research techniques todetermine what debt obligations to buy and sell.Fundamental techniques assess a security’s value basedon an issuer’s financial profile, management, andbusiness prospects while quantitative and technicaltechniques involve a more data-oriented analysis offinancial information, market trends and pricemovements. The “total return” sought by the Portfolioconsists of income earned on the Portfolio’s investmentsplus capital appreciation, if any. The Portfolio mayinvest in U.S. dollar denominated sovereign debt offoreign governments.

The Portfolio utilizes derivatives primarily in the formof U.S. Treasury futures contracts in order to manage thePortfolio’s duration, or interest rate risk. The Portfoliomay enter into derivatives contracts traded onexchanges or in the over the counter market.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve its

TSF-35

Page 90: THRIVENT FLEXIBLE PREMIUM DEFERRED VARIABLE ANNUITY · 2020-04-30 · THRIVENT VARIABLE ANNUITY ACCOUNT C THRIVENT SERIES FUND,INC. PROSPECTUS FOR FLEXIBLE PREMIUM DEFERRED VARIABLE

investment objective and you could lose money byinvesting in the Portfolio.

Government Securities Risk. The Portfolio invests insecurities issued or guaranteed by the U.S. governmentor its agencies and instrumentalities (such as FederalHome Loan Bank, Ginnie Mae, Fannie Mae or FreddieMac securities). Securities issued or guaranteed byFederal Home Loan Banks, Ginnie Mae, Fannie Mae orFreddie Mac are not issued directly by the U.S.government. Ginnie Mae is a wholly owned U.S.corporation that is authorized to guarantee, with thefull faith and credit of the U.S. government, the timelypayment of principal and interest of its securities. Bycontrast, securities issued or guaranteed by U.S.government-related organizations such as Federal HomeLoan Banks, Fannie Mae and Freddie Mac are notbacked by the full faith and credit of the U.S.government. No assurance can be given that the U.S.government would provide financial support to itsagencies and instrumentalities if not required to do soby law. In addition, the value of U.S. governmentsecurities may be affected by changes in the credit ratingof the U.S. government.

Mortgage-Backed and Other Asset-BackedSecurities Risk. The value of mortgage-backed andasset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlyingsuch securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid. In addition, bothmortgage-backed and asset-backed securities aresensitive to changes in the repayment patterns of theunderlying security. If the principal payment on theunderlying asset is repaid faster or slower than theholder of the asset-backed or mortgage-backed securityanticipates, the price of the security may fall,particularly if the holder must reinvest the repaidprincipal at lower rates or must continue to hold thesecurity when interest rates rise. This effect may causethe value of the Portfolio to decline and reduce theoverall return of the Portfolio.

Inflation-Linked Security Risk. Inflation-linked debtsecurities, such as TIPS, are subject to the effects ofchanges in market interest rates caused by factors otherthan inflation (real interest rates). In general, the priceof an inflation-linked security tends to decrease whenreal interest rates increase and can increase when realinterest rates decrease. Interest payments oninflation-linked securities are unpredictable and willfluctuate as the principal and interest are adjusted forinflation. Any increase in the principal amount of aninflation-linked debt security will be considered taxable

ordinary income, even though the Portfolio will notreceive the principal until maturity.

There can also be no assurance that the inflation indexused will accurately measure the real rate of inflation inthe prices of goods and services. The Portfolio’sinvestments in inflation-linked securities may lose valuein the event that the actual rate of inflation is differentthan the rate of the inflation index. In addition,inflation-linked securities are subject to the risk that theConsumer Price Index for All Urban Consumers (CPI-U)or other relevant pricing index may be discontinued,fundamentally altered in a manner materially adverse tothe interests of an investor in the securities, altered bylegislation or Executive Order in a materially adversemanner to the interests of an investor in the securitiesor substituted with an alternative index.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Changes by the Federal Reserve tomonetary policies could affect interest rates and thevalue of some securities. In addition, the phase out ofLIBOR (the offered rate for short-term Eurodollardeposits between major international banks) by the endof 2021 could lead to increased volatility and illiquidityin certain markets that currently rely on LIBOR todetermine interest rates.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Sovereign Debt Risk. Sovereign debt securities areissued or guaranteed by foreign governmental entities.These investments are subject to the risk that agovernmental entity may delay or refuse to pay interestor repay principal on its sovereign debt, due, forexample, to cash flow problems, insufficient foreigncurrency reserves, political considerations, the relativesize of the governmental entity’s debt position inrelation to the economy or the failure to put in placeeconomic reforms required by the InternationalMonetary Fund or other multilateral agencies. If agovernmental entity defaults, it may ask for more timein which to pay or for further loans. There is no legal

process for collecting sovereign debts that a governmentdoes not pay nor are there bankruptcy proceedingsthrough which all or part of the sovereign debt that agovernmental entity has not repaid may be collected.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets. There is also no guarantee thatthe Adviser will be able to effectively implement thePortfolio’s investment objective.

Derivatives Risk. The use of derivatives (such asfutures) involves additional risks and transaction costswhich could leave the Portfolio in a worse position thanif it had not used these instruments. The Portfolioutilizes futures on U.S. Treasuries in order to manageduration. The use of derivatives can lead to lossesbecause of adverse movements in the price or value ofthe underlying asset, index or rate, which may bemagnified by certain features of the contract. Changesin the value of the derivative may not correlate asintended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is the riskthat the other party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Dealer inventories ofbonds are at or near historic lows in relation to marketsize, which has the potential to decrease liquidity andincrease price volatility in the fixed income markets,particularly during periods of economic or market stress.As a result of this decreased liquidity, the Portfolio mayhave to accept a lower price to sell a security, sell othersecurities to raise cash, or give up an investmentopportunity, any of which could have a negative effecton performance.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreak

are uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared tobroad-based securities market indices. The indexdescriptions appear in the �Index Descriptions� sectionof the prospectus. Call 800-847-4836 or visitThrivent.com for performance results current to themost recent month-end.

Effective August 28, 2017, based on approval of thePortfolio’s Board of Directors and shareholders, theportfolio’s investment objective and principal strategieswere changed, which had the effect of converting thePortfolio from one whose securities were selected basedon which securities were in an index to one that isactively managed and invests primarily in U.S.government securities. At the same time, the Portfolio’sname changed from Thrivent Bond Index Portfolio toThrivent Government Bond Portfolio. As a result,performance information presented below with respectto periods prior to August 28, 2017, reflects theperformance of an investment portfolio that wasmaterially different from the investment portfolio ofThrivent Government Bond Portfolio.

The bar chart and the table include the effects ofPortfolio expenses, but not charges or deductionsagainst your variable contract, and assume that you soldyour shares at the end of the period. Because shares ofthe Portfolio are offered through variable life insuranceand variable annuity contracts, you should carefullyreview the variable contract prospectus for informationon applicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

How the Portfolio has performed in the past (before andafter taxes) is not necessarily an indication of how it willperform in the future. Performance informationprovides some indication of the risks of investing in thePortfolio by showing changes in the Portfolio’sperformance over time.

Thrivent High Yield PortfolioInvestment ObjectivesThrivent High Yield Portfolio (the �Portfolio�) seeks toachieve a higher level of income. The Portfolio will alsoconsider growth of capital as a secondary objective.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a % of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the lower of the original purchaseprice or current net asset value) N/A

ANNUAL PORTFOLIO OPERATING EXPENSES(expenses that you pay each year as a percentage ofthe value of your investment)

Thrivent High YieldPortfolio $45 $141 $246 $555

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 48% ofthe average value of its portfolio.

Principal StrategiesUnder normal market conditions, the Portfolio investsat least 80% of its net assets (plus the amount of anyborrowing for investment purposes) in high yield, highrisk bonds, notes, debentures and other debt obligations(including leveraged loans, mortgage-backed securities,convertible bonds, and convertible stock), or preferredstocks. These securities are commonly known as “junkbonds.” At the time of purchase these securities arerated within or below the “BB” major rating category byStandard & Poor’s Corporation or the “Ba” major ratingcategory by Moody’s Investor Services, Inc. or areunrated but considered to be of comparable quality bythe Adviser. The Portfolio invests in securities regardlessof the securities’ maturity average and may also investin foreign securities. Should the Adviser change theinvestments used for purposes of this 80% threshold,you will be notified at least 60 days prior to the change.

The Adviser uses fundamental, quantitative, andtechnical investment research techniques to determinewhat securities to buy and sell. Fundamental techniquesassess a security’s value based on an issuer’s financialprofile, management, and business prospects whilequantitative and technical techniques involve a moredata-oriented analysis of financial information, markettrends and price movements. The Adviser focuses onU.S. companies which it believes have or are expected toachieve adequate cash flows or access to capital marketsfor the payment of principal and interest obligations.

The Portfolio utilizes derivatives primarily in the formof U.S. Treasury futures contracts in order to manage thePortfolio’s duration, or interest rate risk. The Portfoliomay enter into derivatives contracts traded onexchanges or in the over the counter market.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objectives and you could lose money byinvesting in the Portfolio.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected. High yield securities generally have a lessliquid resale market.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Changes by the Federal Reserve tomonetary policies could affect interest rates and thevalue of some securities. In addition, the phase out ofLIBOR (the offered rate for short-term Eurodollardeposits between major international banks) by the endof 2021 could lead to increased volatility and illiquidityin certain markets that currently rely on LIBOR todetermine interest rates.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Convertible Securities Risk. Convertible securities aresubject to the usual risks associated with debt securities,such as interest rate risk and credit risk. Convertiblesecurities also react to changes in the value of thecommon stock into which they convert, and are thussubject to market risk. The Portfolio may also be forcedto convert a convertible security at an inopportunetime, which may decrease the Portfolio’s return.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud or

misrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Prepayment Risk. When interest rates fall, certainobligations will be paid off by the obligor more quicklythan originally anticipated, and a Portfolio may have toinvest the proceeds in securities with lower yields. Inperiods of falling interest rates, the rate of prepaymentstends to increase (as does price fluctuation) as borrowersare motivated to pay off debt and refinance at newlower rates. During such periods, reinvestment of theprepayment proceeds by the management team willgenerally be at lower rates of return than the return onthe assets that were prepaid. Prepayment generallyreduces the yield to maturity and the average life of thesecurity.

Foreign Securities Risk. Foreign securities generallycarry more risk and are more volatile than theirdomestic counterparts, in part because of potential forhigher political and economic risks, lack of reliableinformation and fluctuations in currency exchange rateswhere investments are denominated in currencies otherthan the U.S. dollar. Certain events in foreign marketsmay adversely affect foreign and domestic issuers,including interruptions in the global supply chain,natural disasters and outbreak of infectious diseases. ThePortfolio’s investment in any country could be subjectto governmental actions such as capital or currencycontrols, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome. Foreign securities may also be more difficult toresell than comparable U.S. securities because themarkets for foreign securities are often less liquid. Evenwhen a foreign security increases in price in its localcurrency, the appreciation may be diluted by adversechanges in exchange rates when the security’s value isconverted to U.S. dollars. Foreign withholding taxes alsomay apply and errors and delays may occur in thesettlement process for foreign securities.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Dealer inventories of

bonds are at or near historic lows in relation to marketsize, which has the potential to decrease liquidity andincrease price volatility in the fixed income markets,particularly during periods of economic or market stress.As a result of this decreased liquidity, the Portfolio mayhave to accept a lower price to sell a security, sell othersecurities to raise cash, or give up an investmentopportunity, any of which could have a negative effecton performance.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets. There is also no guarantee thatthe Adviser will be able to effectively implement thePortfolio’s investment objective.

Derivatives Risk. The use of derivatives (such asfutures) involves additional risks and transaction costswhich could leave the Portfolio in a worse position thanif it had not used these instruments. The Portfolioutilizes futures on U.S. Treasuries in order to manageduration. The use of derivatives can lead to lossesbecause of adverse movements in the price or value ofthe underlying asset, index or rate, which may bemagnified by certain features of the contract. Changesin the value of the derivative may not correlate asintended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is the riskthat the other party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared toa broad-based securities market index. The index

description appears in the �Index Descriptions� sectionof the prospectus. Call 800-847-4836 or visitThrivent.com for performance results current to themost recent month-end.

The bar chart and table include the effects of Portfolioexpenses, but not charges or deductions against yourvariable contract, and assume that you sold yourinvestment at the end of the period. Because shares ofthe Portfolio are offered through variable life insuranceand variable annuity contracts, you should carefullyreview the variable contract prospectus for informationon applicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

How a Portfolio has performed in the past is notnecessarily an indication of how it will perform in thefuture. Performance information provides someindication of the risks of investing in the Portfolio byshowing changes in the Portfolio’s performance overtime.

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 101% ofthe average value of its portfolio.

Principal StrategiesThe principal strategies of the Portfolio are to invest ininvestment-grade corporate bonds, government bonds,asset-backed securities, mortgage-backed securities, andother types of debt securities. Asset-backed securities aresecurities backed by notes or receivables originated bybanks, credit card companies or other providers ofcredit.

The Portfolio may invest in foreign securities, includingthose of issuers in emerging markets.

The Adviser uses fundamental, quantitative, andtechnical investment research techniques to determinewhat debt obligations to buy and sell. Fundamentaltechniques assess a security’s value based on an issuer’sfinancial profile, management, and business prospectswhile quantitative and technical techniques involve amore data-oriented analysis of financial information,market trends and price movements.

purchase bonds of any maturity and generally focuseson U.S. companies that it believes are financially soundand have strong cash flow, asset values and interest ordividend earnings. The Adviser purchases bonds offoreign issuers as well.

The Portfolio utilizes derivatives primarily in the formof U.S. Treasury futures contracts in order to manage thePortfolio’s duration, or interest rate risk. The Portfoliomay enter into derivatives contracts traded onexchanges or in the over the counter market.

The Portfolio may invest in securities of any marketsector and may hold a significant amount of securitiesof companies, from time to time, within a single sectorsuch as financials.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Changes by the Federal Reserve tomonetary policies could affect interest rates and thevalue of some securities. In addition, the phase out ofLIBOR (the offered rate for short-term Eurodollardeposits between major international banks) by the endof 2021 could lead to increased volatility and illiquidityin certain markets that currently rely on LIBOR todetermine interest rates.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected. High yield securities generally have a lessliquid resale market.

Government Securities Risk. The Portfolio invests insecurities issued or guaranteed by the U.S. governmentor its agencies and instrumentalities (such as Federal

Home Loan Bank, Ginnie Mae, Fannie Mae or FreddieMac securities). Securities issued or guaranteed byFederal Home Loan Banks, Ginnie Mae, Fannie Mae orFreddie Mac are not issued directly by the U.S.government. Ginnie Mae is a wholly owned U.S.corporation that is authorized to guarantee, with thefull faith and credit of the U.S. government, the timelypayment of principal and interest of its securities. Bycontrast, securities issued or guaranteed by U.S.government-related organizations such as Federal HomeLoan Banks, Fannie Mae and Freddie Mac are notbacked by the full faith and credit of the U.S.government. No assurance can be given that the U.S.government would provide financial support to itsagencies and instrumentalities if not required to do soby law. In addition, the value of U.S. governmentsecurities may be affected by changes in the credit ratingof the U.S. government.

Mortgage-Backed and Other Asset-BackedSecurities Risk. The value of mortgage-backed andasset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlyingsuch securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid. In addition, bothmortgage-backed and asset-backed securities aresensitive to changes in the repayment patterns of theunderlying security. If the principal payment on theunderlying asset is repaid faster or slower than theholder of the asset-backed or mortgage-backed securityanticipates, the price of the security may fall,particularly if the holder must reinvest the repaidprincipal at lower rates or must continue to hold thesecurity when interest rates rise. This effect may causethe value of the Portfolio to decline and reduce theoverall return of the Portfolio.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Foreign Securities Risk. Foreign securities generallycarry more risk and are more volatile than theirdomestic counterparts, in part because of potential for

higher political and economic risks, lack of reliableinformation and fluctuations in currency exchange rateswhere investments are denominated in currencies otherthan the U.S. dollar. Certain events in foreign marketsmay adversely affect foreign and domestic issuers,including interruptions in the global supply chain,natural disasters and outbreak of infectious diseases. ThePortfolio’s investment in any country could be subjectto governmental actions such as capital or currencycontrols, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome. Foreign securities may also be more difficult toresell than comparable U.S. securities because themarkets for foreign securities are often less liquid. Evenwhen a foreign security increases in price in its localcurrency, the appreciation may be diluted by adversechanges in exchange rates when the security’s value isconverted to U.S. dollars. Foreign withholding taxes alsomay apply and errors and delays may occur in thesettlement process for foreign securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets. There is also no guarantee thatthe Adviser will be able to effectively implement thePortfolio’s investment objective.

Financial Sector Risk. To the extent that thefinancials sector continues to represent a significantportion of the Portfolio, the Portfolio will be sensitive tochanges in, and its performance may depend to agreater extent on, factors impacting this sector.Performance of companies in the financials sector maybe adversely impacted by many factors, including,among others, government regulations, economicconditions, credit rating downgrades, changes ininterest rates, and decreased liquidity in credit markets.The impact of more stringent capital requirements,recent or future regulation of any individual financialcompany or recent or future regulation of the financialssector as a whole cannot be predicted. In recent years,cyber attacks and technology malfunctions and failureshave become increasingly frequent in this sector andhave caused significant losses.

Derivatives Risk. The use of derivatives (such asfutures) involves additional risks and transaction costswhich could leave the Portfolio in a worse position thanif it had not used these instruments. The Portfolioutilizes futures on U.S. Treasuries in order to manageduration. The use of derivatives can lead to lossesbecause of adverse movements in the price or value ofthe underlying asset, index or rate, which may be

magnified by certain features of the contract. Changesin the value of the derivative may not correlate asintended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is the riskthat the other party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Emerging Markets Risk. The economic and politicalstructures of developing countries in emerging markets,in most cases, do not compare favorably with the U.S.or other developed countries in terms of wealth andstability, and their financial markets often lack liquidity.Portfolio performance will likely be negatively affectedby portfolio exposure to countries and corporationsdomiciled in or with revenue exposures to countries inthe midst of, among other things, hyperinflation,currency devaluation, trade disagreements, suddenpolitical upheaval, or interventionist governmentpolicies. Portfolio performance may also be negativelyaffected by portfolio exposure to countries andcorporations domiciled in or with revenue exposures tocountries with less developed legal, tax, regulatory, andaccounting systems. Significant buying or selling actionsby a few major investors may also heighten thevolatility of emerging markets. These factors makeinvesting in emerging market countries significantlyriskier than in other countries, and events in any onecountry could cause the Portfolio’s share price todecline.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Dealer inventories ofbonds are at or near historic lows in relation to marketsize, which has the potential to decrease liquidity andincrease price volatility in the fixed income markets,particularly during periods of economic or market stress.As a result of this decreased liquidity, the Portfolio mayhave to accept a lower price to sell a security, sell othersecurities to raise cash, or give up an investmentopportunity, any of which could have a negative effecton performance.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreak

are uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared tobroad-based securities market indices. The indexdescriptions appear in the �Index Descriptions� sectionof the prospectus.

Call 800-847-4836 or visitThrivent.com for performance results current to themost recent month-end.

The bar chart and table include the effects of Portfolioexpenses, but not charges or deductions against yourvariable contract, and assume that you sold yourinvestment at the end of the period.

If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

Thrivent International Allocation PortfolioInvestment ObjectiveThrivent International Allocation Portfolio (the�Portfolio�) seeks long-term capital growth.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a % of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the lower of the original purchaseprice or current net asset value) N/A

ANNUAL PORTFOLIO OPERATING EXPENSES(expenses that you pay each year as a percentage ofthe value of your investment)

Management Fees 0.64%

Other Expenses 0.08%

Total Annual Portfolio Operating Expenses 0.72%

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts.

Although your actual costmay be higher or lower, based on the foregoingassumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent InternationalAllocation Portfolio $74 $230 $401 $894

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate may

indicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 106% ofthe average value of its portfolio.

Principal StrategiesThe Portfolio seeks to achieve its objective by investingprimarily in equity securities of issuers throughout theworld. The Portfolio seeks to diversify its portfoliobroadly among developed and emerging countries andamong multiple asset classes. Under normal marketconditions, the Portfolio invests at least 40% of its netassets in foreign assets. If market conditions are notdeemed favorable by the Adviser, the Portfolio couldinvest a lower percentage, but at least 30% of its netassets in foreign assets. A foreign asset could be aninvestment in an issuer that is organized under the lawsof a foreign jurisdiction; that is traded principally in aforeign country; that derives at least 50% of its revenuesor profits from goods produced or sold, investmentsmade, or services performed in a foreign country or hasat least 50% of its assets in a foreign country; or thatotherwise exposes the Portfolio’s portfolio to theeconomic fortunes and risks of a foreign country. ThePortfolio may also pursue its investment strategy byinvesting in equity derivatives such as futures contractsto either hedge its exposure or gain exposure to certaininvestments.

The Adviser will make asset allocation decisions amongthe various asset classes and has engaged GoldmanSachs Asset Management, L.P. (“GSAM”) to manage thePortfolio’s international small- and mid- cap equityassets. The Adviser will directly manage the remainingassets in the Portfolio.

The Portfolio will generally make the followingallocations among the broad asset classes listed below:

International large-cap growth. . . . . . . . . . . . . . . . . . . . . . . . . . 0-50%International large-cap value. . . . . . . . . . . . . . . . . . . . . . . . . . . . 0-50%International small- and mid-cap equities . . . . . . . . . . . . . . 0-30%Emerging markets equity. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0-25%U.S. securities . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0-10%

The Portfolio’s actual holdings in each broad assetcategory may be outside the applicable allocation rangefrom time to time due to differing investmentperformances among asset classes. These allocationsmay change without shareholder approval or advancenotice to shareholders to the extent consistent withapplicable law.

In buying and selling securities for the Portfolio, theAdviser uses an active strategy. This strategy consists of a

TSF-50

Page 105: THRIVENT FLEXIBLE PREMIUM DEFERRED VARIABLE ANNUITY · 2020-04-30 · THRIVENT VARIABLE ANNUITY ACCOUNT C THRIVENT SERIES FUND,INC. PROSPECTUS FOR FLEXIBLE PREMIUM DEFERRED VARIABLE

disciplined approach that involves computer-aided,quantitative analysis of fundamental, technical andrisk-related factors. The Adviser’s factor model (amethod of analyzing and combining multiple datasources) systematically reviews thousands of stocks,using data such as historical earnings growth andexpected future growth, valuation, price momentum,and other quantitative factors to forecast returnpotential. Then, risk characteristics of potentialinvestments and covariation among securities areanalyzed along with the return forecasts in determiningthe Portfolio’s holdings.

GSAM uses a quantitative style of management, incombination with a qualitative overlay, that emphasizesfundamentally-based stock selection, careful portfolioconstruction and efficient implementation. ThePortfolio’s investments are selected using fundamentalresearch and a variety of quantitative techniques basedon certain investment themes. The Portfolio may makeinvestment decisions that deviate from those generatedby GSAM’s proprietary models, at the discretion ofGSAM. In addition, GSAM may, in its discretion, makechanges to its quantitative techniques, or use otherquantitative techniques that are based on GSAM’sproprietary research.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. Therefore, a principal risk of investing in thePortfolio is that the allocation strategies used and theallocation decisions made will not produce the desiredresults.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Foreign Securities Risk. Foreign securities generallycarry more risk and are more volatile than theirdomestic counterparts, in part because of potential forhigher political and economic risks, lack of reliableinformation and fluctuations in currency exchange rateswhere investments are denominated in currencies otherthan the U.S. dollar. Certain events in foreign marketsmay adversely affect foreign and domestic issuers,including interruptions in the global supply chain,natural disasters and outbreak of infectious diseases. ThePortfolio’s investment in any country could be subjectto governmental actions such as capital or currencycontrols, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome. Foreign securities may also be more difficult toresell than comparable U.S. securities because themarkets for foreign securities are often less liquid. Evenwhen a foreign security increases in price in its localcurrency, the appreciation may be diluted by adversechanges in exchange rates when the security’s value isconverted to U.S. dollars. Foreign withholding taxes alsomay apply and errors and delays may occur in thesettlement process for foreign securities.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

Value Investing Risk. Value style investing includesthe risk that stocks of undervalued companies may notrise as quickly as anticipated if the market doesn’trecognize their intrinsic value or if value stocks are outof favor.

Quantitative Investing Risk. Quantitative InvestingRisk is the risk that securities selected according to aquantitative analysis methodology can performdifferently from the market as a whole based on themodel and the factors used in the analysis, the weightplaced on each factor and changes in the factor’shistorical trends. Such models are based on assumptionsof these and other market factors, and the models maynot take into account certain factors, or perform asintended, and may result in a decline in the value of thePortfolio’s portfolio.

Emerging Markets Risk. The economic and politicalstructures of developing countries in emerging markets,

TSF-51

Page 106: THRIVENT FLEXIBLE PREMIUM DEFERRED VARIABLE ANNUITY · 2020-04-30 · THRIVENT VARIABLE ANNUITY ACCOUNT C THRIVENT SERIES FUND,INC. PROSPECTUS FOR FLEXIBLE PREMIUM DEFERRED VARIABLE

in most cases, do not compare favorably with the U.S.or other developed countries in terms of wealth andstability, and their financial markets often lack liquidity.Portfolio performance will likely be negatively affectedby portfolio exposure to countries and corporationsdomiciled in or with revenue exposures to countries inthe midst of, among other things, hyperinflation,currency devaluation, trade disagreements, suddenpolitical upheaval, or interventionist governmentpolicies. Portfolio performance may also be negativelyaffected by portfolio exposure to countries andcorporations domiciled in or with revenue exposures tocountries with less developed legal, tax, regulatory, andaccounting systems. Significant buying or selling actionsby a few major investors may also heighten thevolatility of emerging markets. These factors makeinvesting in emerging market countries significantlyriskier than in other countries, and events in any onecountry could cause the Portfolio’s share price todecline.

Foreign Currency Risk. The value of a foreigncurrency may decline against the U.S. dollar, whichwould reduce the dollar value of securities denominatedin that currency. The overall impact of such a decline offoreign currency can be significant, unpredictable, andlong lasting, depending on the currencies represented,how each one appreciates or depreciates in relation tothe U.S. dollar, and whether currency positions arehedged. Under normal conditions, the Portfolio doesnot engage in extensive foreign currency hedgingprograms. Further, exchange rate movements arevolatile, and it is not possible to effectively hedge thecurrency risks of many developing countries.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Small Cap Risk. Smaller, less seasoned companiesoften have greater price volatility, lower trading volume,and less liquidity than larger, more establishedcompanies. These companies tend to have smallrevenues, narrower product lines, less managementdepth and experience, small shares of their product orservice markets, fewer financial resources, and lesscompetitive strength than larger companies. Suchcompanies seldom pay significant dividends that couldsoften the impact of a falling market on returns.

Mid Cap Risk. Medium-sized companies often havegreater price volatility, lower trading volume, and lessliquidity than larger, more-established companies. These

companies tend to have smaller revenues, narrowerproduct lines, less management depth and experience,smaller shares of their product or service markets, fewerfinancial resources, and less competitive strength thanlarger companies.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser orsubadviser in assessing the potential of the investmentsin which the Portfolio invests. This assessment ofinvestments may prove incorrect, resulting in losses orpoor performance, even in rising markets. There is alsono guarantee that the Adviser will be able to effectivelyimplement the Portfolio’s investment objective.

Multi-Manager Risk. The investment style employedby the subadviser may not be complementary to that ofthe Adviser. The interplay of the strategy employed bythe subadviser and the Adviser may result in thePortfolio indirectly holding positions in certain types ofsecurities, industries or sectors. These positions may bedetrimental to a Portfolio’s performance dependingupon the performance of those securities and the overalleconomic environment. The multi-manager approachcould result in a high level of portfolio turnover,resulting in higher brokerage expenses and increased taxliability from a Portfolio’s realization of capital gains.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a % of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the lower of the original purchaseprice or current net asset value) N/A

Other Expenses1 1.09%

Total Annual Portfolio Operating Expenses 1.29%

Less Fee Waivers and/or ExpenseReimbursements2 0.83%

Total Annual Portfolio Operating Expenses AfterFee Waivers and/or Expense Reimbursements 0.46%

1 These expenses are based on estimated amounts for the currentfiscal year.

2 The Adviser has contractually agreed, through at least April 30,2021, to waive certain fees and/or reimburse certain expensesassociated with the shares of the Thrivent International IndexPortfolio in order to limit the Total Annual Portfolio OperatingExpenses After Fee Waivers and/or Expense Reimbursements to anannual rate of 0.46% of the average daily net assets of the shares.This contractual provision, however, may be terminated before theindicated termination date upon the mutual agreement betweenthe Independent Directors of the Portfolio and the Adviser.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods. In

addition, the example for the 1 Year period reflects theeffect of the contractual fee waiver and/or expensereimbursement. The example also assumes that yourinvestment has a 5% return each year, and that thePortfolio’s operating expenses remain the same.Although your actual cost may be higher or lower, basedon the foregoing assumptions, your cost would be:

1 Year 3 Years

Thrivent International IndexPortfolio $47 $327

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. Because the Portfolio had notyet commenced operations prior to the date of thisprospectus, the Portfolio’s portfolio turnover rate for themost recent fiscal year end is not yet available.

Principal StrategiesUnder normal circumstances, the Portfolio investssubstantially all of its assets (more than 80% of its netassets, plus the amount of any borrowings forinvestment purposes) in equity securities included inthe MSCI EAFE Index in the proportions in which theyare represented in the index. This is a passivelymanaged Portfolio, which means that the Adviser doesnot actively choose the securities that should make upthe Portfolio, and instead seeks to replicate the MSCIEAFE Index and provide investment results that, beforeexpenses, correspond generally to the total return of theindex. The MSCI EAFE Index captures large- andmid-cap equity securities in developed marketscountries, excluding the U.S. and Canada. As ofMarch 31, 2020, the MSCI EAFE Index consisted of 918constituents in the following 21 developed marketcountry indices: Australia, Austria, Belgium, Denmark,Finland, France, Germany, Hong Kong, Ireland, Israel,Italy, Japan, the Netherlands, New Zealand, Norway,Portugal, Singapore, Spain, Sweden, Switzerland, andthe United Kingdom. If the securities represented in theMSCI EAFE Index were to become concentrated in anyparticular industry, the Portfolio’s investments wouldlikewise be concentrated in securities of issuers in thatindustry; the MSCI EAFE Index is not currentlyconcentrated in any single industry. The MSCI EAFEIndex is a free float-adjusted market capitalization indexthat is designed to provide coverage of the relevant

Page 110: THRIVENT FLEXIBLE PREMIUM DEFERRED VARIABLE ANNUITY · 2020-04-30 · THRIVENT VARIABLE ANNUITY ACCOUNT C THRIVENT SERIES FUND,INC. PROSPECTUS FOR FLEXIBLE PREMIUM DEFERRED VARIABLE

investment opportunity set with an emphasis on indexliquidity, investability and replicability. The MSCI EAFEIndex is adjusted quarterly, and when changes to theindex occur, the Adviser will attempt to replicate thesechanges within the Portfolio. However, any suchchanges may result in slight variations from time totime. The Portfolio may buy and sell equity indexfutures for investment exposure. For liquidity reasons,the Portfolio may invest to some degree in moneymarket instruments.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Foreign Securities Risk. Foreign securities generallycarry more risk and are more volatile than theirdomestic counterparts, in part because of potential forhigher political and economic risks, lack of reliableinformation and fluctuations in currency exchange rateswhere investments are denominated in currencies otherthan the U.S. dollar. Certain events in foreign marketsmay adversely affect foreign and domestic issuers,including interruptions in the global supply chain,natural disasters and outbreak of infectious diseases. ThePortfolio’s investment in any country could be subjectto governmental actions such as capital or currencycontrols, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome. Foreign securities may also be more difficult toresell than comparable U.S. securities because themarkets for foreign securities are often less liquid. Evenwhen a foreign security increases in price in its localcurrency, the appreciation may be diluted by adversechanges in exchange rates when the security’s value isconverted to U.S. dollars. Foreign withholding taxes alsomay apply and errors and delays may occur in thesettlement process for foreign securities.

Foreign Currency Risk. The value of a foreigncurrency may decline against the U.S. dollar, whichwould reduce the dollar value of securities denominatedin that currency. The overall impact of such a decline offoreign currency can be significant, unpredictable, andlong lasting, depending on the currencies represented,how each one appreciates or depreciates in relation tothe U.S. dollar, and whether currency positions arehedged. Under normal conditions, the Portfolio doesnot engage in extensive foreign currency hedgingprograms. Further, exchange rate movements arevolatile, and it is not possible to effectively hedge thecurrency risks of many developing countries.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Mid Cap Risk. Medium-sized companies often havegreater price volatility, lower trading volume, and lessliquidity than larger, more-established companies. Thesecompanies tend to have smaller revenues, narrowerproduct lines, less management depth and experience,smaller shares of their product or service markets, fewerfinancial resources, and less competitive strength thanlarger companies.

Futures Contract Risk. The value of a futurescontract tends to increase and decrease in tandem withthe value of the underlying instrument. The price offutures can be highly volatile; using them could lowertotal return, and the potential loss from futures canexceed the Portfolio’s initial investment in suchcontracts. In addition, the value of the futures contractmay not accurately track the value of the underlyinginstrument.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Global Indexing Strategy/Index Tracking Risk. ThePortfolio is managed with an indexing investmentstrategy, attempting to track the performance of anunmanaged index of securities, regardless of the currentor projected performance of the Index or of the actual

securities comprising the Index. The structure andcomposition of the Index will affect the performance,volatility, and risk of the Index and, consequently, theperformance, volatility, and risk of the Portfolio. Thesecurities of foreign issuers, securities of companies withsignificant foreign exposure, and foreign currencies caninvolve additional risks relating to market, economic,industry, political, regulatory, geopolitical, and otherconditions. Less stringent regulatory, accounting,auditing, and disclosure requirements for issuers andmarkets are more common in certain foreign countriesand may make the data upon which the Index is basedunreliable or stale. Enforcing legal rights can be difficult,costly, and slow in certain foreign countries, and can beparticularly difficult against foreign governments. Whilethe Adviser seeks to track the performance of the Index(i.e., achieve a high degree of correlation with theIndex), the Portfolio’s return may not match the returnof the Index. The Portfolio incurs a number of operatingexpenses not applicable to the Index, and incurs costs inbuying and selling securities. In addition, the Portfoliomay not be fully invested at times, generally as a resultof cash flows into or out of the Portfolio or reserves ofcash held by the Portfolio to meet redemptions. TheAdviser may attempt to replicate the Index return byinvesting in fewer than all of the securities in the Index,or in some securities not included in the Index,potentially increasing the risk of divergence between thePortfolio’s return and that of the Index.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

Thrivent Large CapGrowth Portfolio $45 $141 $246 $555

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 58% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in equity securitiesof large companies. The Adviser focuses mainly on theequity securities of large domestic and internationalcompanies which have market capitalizationsequivalent to those included in widely known indicessuch as the Russell 1000 Growth Index, S&P 500 Index,or the large company market capitalizationclassifications published by Lipper, Inc. Thesecompanies typically have a market capitalization ofapproximately $8 billion or more. Should the Adviserchange the investments used for purposes of this 80%threshold, you will be notified at least 60 days prior tothe change.

The Portfolio seeks to achieve its investment objectiveby investing in common stocks. The Adviser usesfundamental, quantitative, and technical investmentresearch techniques and focuses on stocks of companiesthat it believes have demonstrated and will sustainabove-average earnings growth over time, or which areexpected to develop rapid sales and earnings growth inthe future when compared to the economy and stockmarket as a whole. Many such companies are in thetechnology sector and the Portfolio may at times have ahigher concentration in this industry.

The Portfolio may sell securities for a variety of reasons,such as to secure gains, limit losses, or reposition assetsinto more promising opportunities.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able to

attain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Technology-Oriented Companies Risk. Commonstocks of companies that rely extensively on technology,science or communications in their productdevelopment or operations may be more volatile thanthe overall stock market and may or may not move intandem with the overall stock market. Technology,science and communications are rapidly changingfields, and stocks of these companies, especially ofsmaller or unseasoned companies, may be subject tomore abrupt or erratic market movements than thestock market in general. There are significantcompetitive pressures among technology-orientedcompanies and the products or operations of suchcompanies may become obsolete quickly. In addition,these companies may have limited product lines,markets or financial resources and the management ofsuch companies may be more dependent upon one or afew key people.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets. There is also no guarantee thatthe Adviser will be able to effectively implement thePortfolio’s investment objective.

Foreign Securities Risk. Foreign securities generallycarry more risk and are more volatile than theirdomestic counterparts, in part because of potential forhigher political and economic risks, lack of reliableinformation and fluctuations in currency exchange rateswhere investments are denominated in currencies otherthan the U.S. dollar. Certain events in foreign marketsmay adversely affect foreign and domestic issuers,including interruptions in the global supply chain,natural disasters and outbreak of infectious diseases. ThePortfolio’s investment in any country could be subjectto governmental actions such as capital or currencycontrols, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome. Foreign securities may also be more difficult toresell than comparable U.S. securities because themarkets for foreign securities are often less liquid. Evenwhen a foreign security increases in price in its localcurrency, the appreciation may be diluted by adversechanges in exchange rates when the security’s value isconverted to U.S. dollars. Foreign withholding taxes alsomay apply and errors and delays may occur in thesettlement process for foreign securities.

Non-Diversified Risk. The Portfolio is not“diversified” within the meaning of the 1940 Act. Thatmeans the Portfolio may invest a greater percentage ofits assets in the securities of any single issuer comparedto other funds. A non-diversified portfolio is generallymore susceptible than a diversified portfolio to the riskthat events or developments affecting a particular issueror industry will significantly affect the Portfolio’sperformance.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods.The example also assumes that your investment has a5% return each year, and that the Portfolio’s operatingexpenses remain the same. Although your actual costmay be higher or lower, based on the foregoingassumptions, your cost would be:

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 3% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio investssubstantially all of its assets (more than 80% of its netassets, plus the amount of any borrowings forinvestment purposes) in the large company commonstocks included in the S&P 500 Index in the proportionsin which they are represented in the index. This is apassively managed Portfolio, which means that theAdviser does not actively choose the securities thatshould make up the Portfolio. The S&P 500 Index iscomprised of 500 domestic large company stocks.Accordingly, the Portfolio invests in stocks of largercompanies from a broad range of industries. The S&P500 Index is adjusted quarterly, and when changes tothe index occur, the Adviser will attempt to replicatethese changes within the Portfolio. However, any suchchanges may result in slight variations from time totime. The Portfolio may buy and sell equity indexfutures for investment exposure. For liquidity reasons,the Portfolio may invest to some degree in moneymarket instruments.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities markets

may also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Futures Contract Risk. The value of a futurescontract tends to increase and decrease in tandem withthe value of the underlying instrument. The price offutures can be highly volatile; using them could lowertotal return, and the potential loss from futures canexceed the Portfolio’s initial investment in suchcontracts. In addition, the value of the futures contractmay not accurately track the value of the underlyinginstrument.

Indexing Strategy/Index Tracking Risk. ThePortfolio is managed with an indexing investmentstrategy, attempting to track the performance of anunmanaged index of securities, regardless of the currentor projected performance of the Index or of the actualsecurities comprising the Index. The structure andcomposition of the Index will affect the performance,volatility, and risk of the Index and, consequently, theperformance, volatility, and risk of the Portfolio. Whilethe Adviser seeks to track the performance of the Index(i.e., achieve a high degree of correlation with theIndex), the Portfolio’s return may not match the returnof the Index. The Portfolio incurs a number of operatingexpenses not applicable to the Index, and incurs costs inbuying and selling securities. In addition, the Portfoliomay not be fully invested at times, generally as a resultof cash flows into or out of the Portfolio or reserves ofcash held by the Portfolio to meet redemptions. TheAdviser may attempt to replicate the Index return byinvesting in fewer than all of the securities in the Index,or in some securities not included in the Index,potentially increasing the risk of divergence between thePortfolio’s return and that of the Index.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global business

disruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared toa broad-based securities market index. The indexdescription appears in the �Index Descriptions� sectionof the prospectus. Call 800-847-4836 or visitThrivent.com for performance results current to themost recent month-end.

The bar chart and table include the effects of Portfolioexpenses, but not charges or deductions against yourvariable contract, and assume that you sold yourinvestment at the end of the period. Because shares ofthe Portfolio are offered through variable life insuranceand variable annuity contracts, you should carefullyreview the variable contract prospectus for informationon applicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

How a Portfolio has performed in the past is notnecessarily an indication of how it will perform in thefuture. Performance information provides someindication of the risks of investing in the Portfolio byshowing changes in the Portfolio’s performance overtime.

Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods.The example also assumes that your investment has a5% return each year, and that the Portfolio’s operatingexpenses remain the same. Although your actual costmay be higher or lower, based on the foregoingassumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent Large CapValue Portfolio $64 $202 $351 $786

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate may

indicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 18% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in equity securitiesof large companies. The Adviser focuses mainly on theequity securities of large domestic and internationalcompanies which have market capitalizationsequivalent to those included in widely known indicessuch as the Russell 1000 Value Index, S&P 500 Index, orthe large company market capitalization classificationspublished by Lipper, Inc. These companies typicallyhave a market capitalization of approximately $8 billionor more. Should the Adviser change the investmentsused for purposes of this 80% threshold, we will notifyyou at least 60 days prior to the change.

The Portfolio seeks to achieve its investment objectiveby investing primarily in common stocks. The Adviseruses fundamental, quantitative, and technicalinvestment research techniques and focuses on stocks ofcompanies that it believes are undervalued in relation totheir long-term earnings power or asset value. Thesestocks typically, but not always, have below averageprice-to-earnings and price-to-book value ratios. ThePortfolio may sell securities for a variety of reasons, suchas to secure gains, limit losses, or reposition assets intomore promising opportunities.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Value Investing Risk. Value style investing includesthe risk that stocks of undervalued companies may notrise as quickly as anticipated if the market doesn’trecognize their intrinsic value or if value stocks are outof favor.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimes

rapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets. There is also no guarantee thatthe Adviser will be able to effectively implement thePortfolio’s investment objective.

Foreign Securities Risk. Foreign securities generallycarry more risk and are more volatile than theirdomestic counterparts, in part because of potential forhigher political and economic risks, lack of reliableinformation and fluctuations in currency exchange rateswhere investments are denominated in currencies otherthan the U.S. dollar. Certain events in foreign marketsmay adversely affect foreign and domestic issuers,including interruptions in the global supply chain,natural disasters and outbreak of infectious diseases. ThePortfolio’s investment in any country could be subjectto governmental actions such as capital or currencycontrols, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome. Foreign securities may also be more difficult toresell than comparable U.S. securities because themarkets for foreign securities are often less liquid. Evenwhen a foreign security increases in price in its localcurrency, the appreciation may be diluted by adversechanges in exchange rates when the security’s value isconverted to U.S. dollars. Foreign withholding taxes alsomay apply and errors and delays may occur in thesettlement process for foreign securities.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared tobroad-based securities market indices. The indexdescriptions appear in the �Index Descriptions� sectionof the prospectus.

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turns

over” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 101% ofthe average value of its portfolio.

Principal StrategiesThe principal strategies of the Portfolio are to invest ininvestment-grade corporate bonds, government bonds,municipal bonds, mortgage-backed securities (includingcommercially backed ones), asset-backed securities, andcollateralized debt obligations (including collateralizedloan obligations). Asset-backed securities are securitiesbacked by notes or receivables originated by banks,credit card companies, or other providers of credit;collateralized debt obligations are types of asset-backedsecurities. Under normal market conditions, thePortfolio invests at least 80% of its net assets (plus theamount of any borrowing for investment purposes) indebt securities or preferred stock in at least the “Baa”major rating category by Moody’s or at least in the“BBB” major rating category by S&P or unratedsecurities considered to be of comparable quality by thePortfolio’s Adviser, with the dollar-weighted averageeffective maturity for the Portfolio expected to bebetween one and five years. Should the Adviser changethe investments used for purposes of this 80%threshold, you will be notified at least 60 days prior tothe change.

The Portfolio may also invest in high yield, high riskbonds, notes, debentures and other debt obligations orpreferred stock commonly known as “junk bonds.” Atthe time of purchase, these securities are rated within orbelow the “BB” major rating category by S&P or the“Ba” major rating category by Moody’s or are unratedbut considered to be of comparable quality by theAdviser.

The Adviser uses fundamental, quantitative, andtechnical investment research techniques to determinewhat debt obligations to buy and sell. Fundamentaltechniques assess a security’s value based on an issuer’sfinancial profile, management, and business prospectswhile quantitative and technical techniques involve amore data-oriented analysis of financial information,market trends and price movements. The Adviserfocuses on companies that it believes are financiallysound and have strong cash flow, asset values andinterest or dividend earnings, and may invest in U.S.dollar-denominated debt of foreign companies.

The Portfolio utilizes derivatives primarily in the formof U.S. Treasury futures contracts in order to manage thePortfolio’s duration, or interest rate risk. The Portfolio

may enter into derivatives contracts traded onexchanges or in the over the counter market.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Government Securities Risk. The Portfolio invests insecurities issued or guaranteed by the U.S. governmentor its agencies and instrumentalities (such as FederalHome Loan Bank, Ginnie Mae, Fannie Mae or FreddieMac securities). Securities issued or guaranteed byFederal Home Loan Banks, Ginnie Mae, Fannie Mae orFreddie Mac are not issued directly by the U.S.government. Ginnie Mae is a wholly owned U.S.corporation that is authorized to guarantee, with thefull faith and credit of the U.S. government, the timelypayment of principal and interest of its securities. Bycontrast, securities issued or guaranteed by U.S.government-related organizations such as Federal HomeLoan Banks, Fannie Mae and Freddie Mac are notbacked by the full faith and credit of the U.S.government. No assurance can be given that the U.S.government would provide financial support to itsagencies and instrumentalities if not required to do soby law. In addition, the value of U.S. governmentsecurities may be affected by changes in the credit ratingof the U.S. government.

Mortgage-Backed and Other Asset-BackedSecurities Risk. The value of mortgage-backed andasset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlyingsuch securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid. In addition, bothmortgage-backed and asset-backed securities aresensitive to changes in the repayment patterns of theunderlying security. If the principal payment on theunderlying asset is repaid faster or slower than theholder of the asset-backed or mortgage-backed securityanticipates, the price of the security may fall,particularly if the holder must reinvest the repaidprincipal at lower rates or must continue to hold thesecurity when interest rates rise. This effect may causethe value of the Portfolio to decline and reduce theoverall return of the Portfolio.

Collateralized Debt Obligations Risk. The risks ofan investment in a collateralized debt obligation(“CDO”) depend largely on the quality and type of thecollateral and the tranche of the CDO in which thePortfolio invests. In addition to the typical risksassociated with fixed income securities and asset-backedsecurities, CDOs carry additional risks including, but

not limited to: (i) the possibility that distributions fromcollateral securities will not be adequate to makeinterest or other payments; (ii) the risk that thecollateral may default, decline in value, and/or bedowngraded; (iii) the Portfolio may invest in tranches ofCDOs that are subordinate to other tranches; (iv) thestructure and complexity of the transaction and thelegal documents could lead to disputes among investorsregarding the characterization of proceeds; (v) theinvestment return achieved by the Portfolio could besignificantly different than those predicted by financialmodels; (vi) the lack of a readily available secondarymarket for CDOs; (vii) risk of forced “fire sale”liquidation due to technical defaults such as coveragetest failures; and (viii) the CDO’s manager may performpoorly.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Changes by the Federal Reserve tomonetary policies could affect interest rates and thevalue of some securities. In addition, the phase out ofLIBOR (the offered rate for short-term Eurodollardeposits between major international banks) by the endof 2021 could lead to increased volatility and illiquidityin certain markets that currently rely on LIBOR todetermine interest rates.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Futures Contract Risk. The value of a futurescontract tends to increase and decrease in tandem withthe value of the underlying instrument. The price offutures can be highly volatile; using them could lowertotal return, and the potential loss from futures canexceed the Portfolio’s initial investment in suchcontracts. In addition, the value of the futures contractmay not accurately track the value of the underlyinginstrument.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected. High yield securities generally have a lessliquid resale market.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets. There is also no guarantee thatthe Adviser will be able to effectively implement thePortfolio’s investment objective.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Dealer inventories ofbonds are at or near historic lows in relation to marketsize, which has the potential to decrease liquidity andincrease price volatility in the fixed income markets,particularly during periods of economic or market stress.As a result of this decreased liquidity, the Portfolio mayhave to accept a lower price to sell a security, sell othersecurities to raise cash, or give up an investmentopportunity, any of which could have a negative effecton performance.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared toa broad-based securities market index.

Thrivent Low Volatility Equity PortfolioInvestment ObjectiveThrivent Low Volatility Equity Portfolio (the �Portfolio�)seeks long-term capital appreciation with lowervolatility relative to the global equity markets. ThePortfolio’s investment objective may be changedwithout shareholder approval.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a % of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the lower of the original purchaseprice or current net asset value) N/A

Management Fees 0.60%

Other Expenses 0.56%

Total Annual Portfolio Operating Expenses 1.16%

Less Fee Waivers and/or ExpenseReimbursements1 0.36%

Total Annual Portfolio Operating Expenses AfterFee Waivers and/or Expense Reimbursements 0.80%

1 The Adviser has contractually agreed, through at least April 30,2021, to waive a portion of the management fees associated withthe shares of the Thrivent Low Volatility Equity Portfolio in orderto limit the Total Annual Portfolio Operating Expenses After FeeWaivers and/or Expense Reimbursements to an annual rate of0.80% of the average daily net assets of the shares. This contractualprovision, however, may be terminated before the indicatedtermination date upon the mutual agreement between theIndependent Directors of the Portfolio and the Adviser.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods. In

addition, the example for the 1 Year period reflects theeffect of the contractual fee waiver and/or expensereimbursement. The example also assumes that yourinvestment has a 5% return each year, and that thePortfolio’s operating expenses remain the same.Although your actual cost may be higher or lower, basedon the foregoing assumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent LowVolatility EquityPortfolio $82 $333 $604 $1,377

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 53% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in equity securities.The Portfolio’s investments are diversified globally. ThePortfolio may invest in securities denominated in U.S.dollars and the currencies of the foreign countries inwhich it may invest. The Portfolio typically has fullcurrency exposure to those markets in which it invests.The Portfolio may buy or sell equity index futures forinvestment exposure or hedging purposes. The Portfoliomay invest in securities of any market capitalization,including small- and mid-cap securities.

In seeking to achieve the Portfolio’s investmentobjective, the Adviser employs investment managementtechniques to identify securities that exhibit lowvolatility returns. Volatility refers to the variation insecurity and market prices over time. Over a full marketcycle, the Portfolio seeks to produce returns similar tothe MSCI World Minimum Volatility Index – USD NetReturns. It is expected that the Portfolio will generallyunderperform the global equity markets during periodsof strong market performance.

In buying and selling securities for the Portfolio, theAdviser uses an active strategy. This strategy consists of adisciplined approach that involves computer-aided,quantitative analysis of fundamental, technical andrisk-related factors. The Adviser’s factor model (a

TSF-76

Page 131: THRIVENT FLEXIBLE PREMIUM DEFERRED VARIABLE ANNUITY · 2020-04-30 · THRIVENT VARIABLE ANNUITY ACCOUNT C THRIVENT SERIES FUND,INC. PROSPECTUS FOR FLEXIBLE PREMIUM DEFERRED VARIABLE

method of analyzing and combining multiple datasources) systematically reviews thousands of stocks,using data such as historical earnings growth andexpected future growth, valuation, price momentum,and other quantitative factors to forecast returnpotential. Then, risk characteristics of potentialinvestments and covariation among securities areanalyzed along with the return forecasts in determiningthe Portfolio’s holdings to produce a portfolio withreduced volatility.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Quantitative Investing Risk. Quantitative InvestingRisk is the risk that securities selected according to aquantitative analysis methodology can performdifferently from the market as a whole based on themodel and the factors used in the analysis, the weightplaced on each factor and changes in the factor’shistorical trends. Such models are based on assumptionsof these and other market factors, and the models maynot take into account certain factors, or perform asintended, and may result in a decline in the value of thePortfolio’s portfolio.

Foreign Securities Risk. Foreign securities generallycarry more risk and are more volatile than theirdomestic counterparts, in part because of potential forhigher political and economic risks, lack of reliableinformation and fluctuations in currency exchange rateswhere investments are denominated in currencies otherthan the U.S. dollar. Certain events in foreign marketsmay adversely affect foreign and domestic issuers,including interruptions in the global supply chain,

natural disasters and outbreak of infectious diseases. ThePortfolio’s investment in any country could be subjectto governmental actions such as capital or currencycontrols, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome. Foreign securities may also be more difficult toresell than comparable U.S. securities because themarkets for foreign securities are often less liquid. Evenwhen a foreign security increases in price in its localcurrency, the appreciation may be diluted by adversechanges in exchange rates when the security’s value isconverted to U.S. dollars. Foreign withholding taxes alsomay apply and errors and delays may occur in thesettlement process for foreign securities.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Mid Cap Risk. Medium-sized companies often havegreater price volatility, lower trading volume, and lessliquidity than larger, more-established companies. Thesecompanies tend to have smaller revenues, narrowerproduct lines, less management depth and experience,smaller shares of their product or service markets, fewerfinancial resources, and less competitive strength thanlarger companies.

Foreign Currency Risk. The value of a foreigncurrency may decline against the U.S. dollar, whichwould reduce the dollar value of securities denominatedin that currency. The overall impact of such a decline offoreign currency can be significant, unpredictable, andlong lasting, depending on the currencies represented,how each one appreciates or depreciates in relation tothe U.S. dollar, and whether currency positions arehedged. Under normal conditions, the Portfolio doesnot engage in extensive foreign currency hedgingprograms. Further, exchange rate movements arevolatile, and it is not possible to effectively hedge thecurrency risks of many developing countries.

Futures Contract Risk. The value of a futurescontract tends to increase and decrease in tandem withthe value of the underlying instrument. The price offutures can be highly volatile; using them could lowertotal return, and the potential loss from futures canexceed the Portfolio’s initial investment in suchcontracts. In addition, the value of the futures contractmay not accurately track the value of the underlyinginstrument.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets. There is also no guarantee thatthe Adviser will be able to effectively implement thePortfolio’s investment objective.

Derivatives Risk. The use of derivatives (such asfutures) involves additional risks and transaction costswhich could leave the Portfolio in a worse position thanif it had not used these instruments. The Portfolioutilizes equity futures in order to increase or decrease itsexposure to various asset classes at a lower cost thantrading stocks directly. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is the riskthat the other party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for the one-year period and since inceptioncompared to a broad-based securities market index.

1 Year 3 Years

Thrivent Mid Cap GrowthPortfolio $87 $908

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. Because the Portfolio had notyet commenced operations prior to the date of thisprospectus, the Portfolio’s portfolio turnover rate for themost recent fiscal year end is not yet available.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in equity securitiesof mid-sized companies. The Adviser focuses mainly onthe equity securities of mid-sized U.S. companies whichhave market capitalizations equivalent to thoseincluded in widely known indices such as the RussellMidcap Growth Index, S&P MidCap 400 Index, or themid-sized company market capitalization classificationspublished by Lipper, Inc. These companies typicallyhave a market capitalization of approximately $2 billionto $25 billion. Should the Adviser change theinvestments used for purposes of this 80% threshold,you will be notified at least 60 days prior to the change.

The Portfolio seeks to achieve its investment objectiveby investing primarily in common stocks. The Adviseruses fundamental, quantitative, and technicalinvestment research techniques and focuses on stocks ofcompanies that it believes have demonstrated andbelieves will sustain above average revenue and earningsgrowth over time, or which are expected to developrapid sales and earnings growth in the future whencompared to the economy and stock market as a whole.Many such companies are in the technology sector andthe Portfolio may at times have a higher concentrationin this industry.

The Adviser may sell securities for a variety of reasons,such as to secure gains, limit losses, or reposition assetsto more promising opportunities.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Mid Cap Risk. Medium-sized companies often havegreater price volatility, lower trading volume, and lessliquidity than larger, more-established companies. Thesecompanies tend to have smaller revenues, narrowerproduct lines, less management depth and experience,smaller shares of their product or service markets, fewerfinancial resources, and less competitive strength thanlarger companies.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Technology-Oriented Companies Risk. Commonstocks of companies that rely extensively on technology,science or communications in their productdevelopment or operations may be more volatile thanthe overall stock market and may or may not move intandem with the overall stock market. Technology,science and communications are rapidly changing

fields, and stocks of these companies, especially ofsmaller or unseasoned companies, may be subject tomore abrupt or erratic market movements than thestock market in general. There are significantcompetitive pressures among technology-orientedcompanies and the products or operations of suchcompanies may become obsolete quickly. In addition,these companies may have limited product lines,markets or financial resources and the management ofsuch companies may be more dependent upon one or afew key people.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets. There is also no guarantee thatthe Adviser will be able to effectively implement thePortfolio’s investment objective.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds.

If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods.The example also assumes that your investment has a5% return each year, and that the Portfolio’s operatingexpenses remain the same. Although your actual costmay be higher or lower, based on the foregoingassumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent Mid CapIndex Portfolio $27 $84 $146 $331

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 17% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio investssubstantially all of its assets (more than 80% of its netassets, plus the amount of any borrowings forinvestment purposes) in mid-sized company stocksincluded in the S&P MidCap 400 Index in theproportions in which they are represented in the Index.This is a passively managed Portfolio, which means thatthe Adviser does not actively choose the securities thatshould make up the Portfolio. The S&P MidCap 400Index is a capitalization weighted index of 400 mediumcapitalization stocks chosen for market size, liquidity,and industry representation. Accordingly, the Portfolioinvests in stocks of medium-sized companies from abroad range of industries. The S&P MidCap 400 Index isadjusted quarterly and when changes to the indexoccur, the Adviser will attempt to replicate thesechanges within the Portfolio. However, any suchchanges may result in slight variations from the index.The Portfolio may buy and sell equity index futures forinvestment exposure. For liquidity reasons, the Portfoliomay invest, to some degree, in money marketinstruments.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Mid Cap Risk. Medium-sized companies often havegreater price volatility, lower trading volume, and lessliquidity than larger, more-established companies. Thesecompanies tend to have smaller revenues, narrowerproduct lines, less management depth and experience,smaller shares of their product or service markets, fewerfinancial resources, and less competitive strength thanlarger companies.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. The

value of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Futures Contract Risk. The value of a futurescontract tends to increase and decrease in tandem withthe value of the underlying instrument. The price offutures can be highly volatile; using them could lowertotal return, and the potential loss from futures canexceed the Portfolio’s initial investment in suchcontracts. In addition, the value of the futures contractmay not accurately track the value of the underlyinginstrument.

Indexing Strategy/Index Tracking Risk. ThePortfolio is managed with an indexing investmentstrategy, attempting to track the performance of anunmanaged index of securities, regardless of the currentor projected performance of the Index or of the actualsecurities comprising the Index. The structure andcomposition of the Index will affect the performance,volatility, and risk of the Index and, consequently, theperformance, volatility, and risk of the Portfolio. Whilethe Adviser seeks to track the performance of the Index(i.e., achieve a high degree of correlation with theIndex), the Portfolio’s return may not match the returnof the Index. The Portfolio incurs a number of operatingexpenses not applicable to the Index, and incurs costs inbuying and selling securities. In addition, the Portfoliomay not be fully invested at times, generally as a resultof cash flows into or out of the Portfolio or reserves ofcash held by the Portfolio to meet redemptions. TheAdviser may attempt to replicate the Index return byinvesting in fewer than all of the securities in the Index,or in some securities not included in the Index,potentially increasing the risk of divergence between thePortfolio’s return and that of the Index.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared toa broad-based securities market index. The indexdescription appears in the �Index Descriptions� sectionof the prospectus. Call 800-847-4836 or visitThrivent.com for performance results current to themost recent month-end.

The bar chart and table include the effects of Portfolioexpenses, but not charges or deductions against yourvariable contract, and assume that you sold yourinvestment at the end of the period. Because shares ofthe Portfolio are offered through variable life insuranceand variable annuity contracts, you should carefullyreview the variable contract prospectus for informationon applicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turns

over” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 34% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in equity securitiesof mid-sized companies.

These companies typically have a marketcapitalization of approximately $2 billion to $25 billion.Should the Adviser change the investments used forpurposes of this 80% threshold, you will be notified atleast 60 days prior to the change.

The Portfolio seeks to achieve its investment objectiveby investing in common stocks. The Adviser usesfundamental, quantitative, and technical investmentresearch techniques to determine what securities to buyand sell. Fundamental techniques assess a security’svalue based on an issuer’s financial profile,management, and business prospects while quantitativeand technical techniques involve a more data-orientedanalysis of financial information, market trends andprice movements. The Adviser generally looks formid-sized companies that, in its opinion:

• have prospects for growth in their sales andearnings;

• are in an industry with a good economic outlook;• have high-quality management; and/or• have a strong financial position.

The Adviser may sell securities for a variety of reasons,such as to secure gains, limit losses, or reposition assetsto more promising opportunities.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Total Annual Portfolio Operating Expenses 3.88%

Less Fee Waivers and/or ExpenseReimbursements2 2.98%

Total Annual Portfolio Operating Expenses AfterFee Waivers and/or Expense Reimbursements 0.90%

1 These expenses are based on estimated amounts for the currentfiscal year.

2 The Adviser has contractually agreed, through at least April 30,2021, to waive certain fees and/or reimburse certain expensesassociated with the shares of the Thrivent Mid Cap Value Portfolioin order to limit the Total Annual Portfolio Operating ExpensesAfter Fee Waivers and/or Expense Reimbursements to an annualrate of 0.90% of the average daily net assets of the shares. Thiscontractual provision, however, may be terminated before theindicated termination date upon the mutual agreement betweenthe Independent Directors of the Portfolio and the Adviser.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods. In

addition, the example for the 1 Year period reflects theeffect of the contractual fee waiver and/or expensereimbursement. The example also assumes that yourinvestment has a 5% return each year, and that thePortfolio’s operating expenses remain the same.Although your actual cost may be higher or lower, basedon the foregoing assumptions, your cost would be:

1 Year 3 Years

Thrivent Mid Cap Value Portfolio $92 $909

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. Because the Portfolio had notyet commenced operations prior to the date of thisprospectus, the Portfolio’s portfolio turnover rate for themost recent fiscal year end is not yet available.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in equity securitiesof mid-sized companies. The Adviser focuses mainly onthe equity securities of mid-sized U.S. companies whichhave market capitalizations equivalent to thoseincluded in widely known indices such as the RussellMidcap Value Index, S&P MidCap 400 Index, or themid-sized company market capitalization classificationspublished by Lipper, Inc. These companies typicallyhave a market capitalization of approximately $2 billionto $25 billion. Should the Adviser change theinvestments used for purposes of this 80% threshold,you will be notified at least 60 days prior to the change.

The Portfolio seeks to achieve its investment objectiveby investing primarily in common stocks. The Adviseruses fundamental, quantitative, and technicalinvestment research techniques and focuses on stocks ofcompanies that it believes are undervalued in relation totheir long-term earnings power or asset value. Thesestocks typically, but not always, have below averageprice-to-earnings and price-to-book value ratios. TheAdviser may sell securities for a variety of reasons, suchas to secure gains, limit losses, or reposition assets tomore promising opportunities.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Mid Cap Risk. Medium-sized companies often havegreater price volatility, lower trading volume, and lessliquidity than larger, more-established companies. Thesecompanies tend to have smaller revenues, narrowerproduct lines, less management depth and experience,smaller shares of their product or service markets, fewerfinancial resources, and less competitive strength thanlarger companies.

Value Investing Risk. Value style investing includesthe risk that stocks of undervalued companies may notrise as quickly as anticipated if the market doesn’trecognize their intrinsic value or if value stocks are outof favor.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets. There is also no guarantee that

the Adviser will be able to effectively implement thePortfolio’s investment objective.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

Thrivent ModerateAllocation Portfolio $65 $242 $433 $986

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 136% ofthe average value of its portfolio.

Principal StrategiesThe Portfolio pursues its objective by investing in acombination of other funds managed by the Adviser oran affiliate and directly held financial instruments. ThePortfolio is designed for investors who seek moderatelong-term capital growth with reasonable stability ofprincipal and are comfortable with moderate levels ofrisk and volatility. The Portfolio uses a prescribed assetallocation strategy involving a two-step process that isdesigned to achieve its desired risk tolerance. The firststep is the construction of a model for the allocation ofthe Portfolio’s assets across broad asset categories(namely, equity securities and debt securities). Thesecond step involves the determination of sub-classeswithin the broad asset categories and target weightings(i.e., what the Adviser determines is the strategicallocation) for these sub-classes. Sub-classes for equitysecurities may be based on market capitalization,investment style (such as growth or value), or economicsector. Sub-classes for debt securities may be based onmaturity, duration, security type or credit rating (highyield—commonly known as “junk bonds”—orinvestment grade).

The use of target weightings for various sub-classeswithin broad asset categories is intended as a multi-styleapproach to reduce the risk of investing in securitieshaving common characteristics. The Portfolio may buyand sell futures contracts to either hedge its exposure orobtain exposure to certain investments.

The Portfolio may invest in foreign securities, includingthose of issuers in emerging markets. An “emergingmarket” country is any country determined by theAdviser to have an emerging market economy,considering factors such as the country’s credit rating,its political and economic stability and the developmentof its financial and capital markets.

Under normal circumstances, the Portfolio invests inthe following broad asset classes within the rangesgiven:

The Portfolio’s actual holdings in each broad assetcategory may be outside the applicable allocation rangefrom time to time due to differing investmentperformance among asset categories. The Adviser willrebalance the Portfolio at least annually so that itsholdings are within the ranges for the broad assetcategories.

The Portfolio pursues its investment strategy byinvesting primarily in other mutual funds managed bythe Adviser or an affiliate.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. Therefore, a principal risk of investing in thePortfolio is that the allocation strategies used and theallocation decisions made will not produce the desiredresults.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Changes by the Federal Reserve tomonetary policies could affect interest rates and thevalue of some securities. In addition, the phase out ofLIBOR (the offered rate for short-term Eurodollardeposits between major international banks) by the endof 2021 could lead to increased volatility and illiquidityin certain markets that currently rely on LIBOR todetermine interest rates.

Page 153: THRIVENT FLEXIBLE PREMIUM DEFERRED VARIABLE ANNUITY · 2020-04-30 · THRIVENT VARIABLE ANNUITY ACCOUNT C THRIVENT SERIES FUND,INC. PROSPECTUS FOR FLEXIBLE PREMIUM DEFERRED VARIABLE

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Mid Cap Risk. Medium-sized companies often havegreater price volatility, lower trading volume, and lessliquidity than larger, more-established companies. Thesecompanies tend to have smaller revenues, narrowerproduct lines, less management depth and experience,smaller shares of their product or service markets, fewerfinancial resources, and less competitive strength thanlarger companies.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Other Funds Risk. Because the Portfolio invests inother funds managed by the Adviser or an affiliate(“Other Funds”), the performance of the Portfolio isdependent, in part, upon the performance of OtherFunds in which the Portfolio may invest. As a result, thePortfolio is subject to the same risks as those faced bythe Other Funds. In addition, Other Funds may besubject to additional fees and expenses that will beborne by the Portfolio.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected. High yield securities generally have a lessliquid resale market.

Foreign Securities Risk. Foreign securities generallycarry more risk and are more volatile than theirdomestic counterparts, in part because of potential forhigher political and economic risks, lack of reliableinformation and fluctuations in currency exchange rateswhere investments are denominated in currencies otherthan the U.S. dollar. Certain events in foreign marketsmay adversely affect foreign and domestic issuers,

including interruptions in the global supply chain,natural disasters and outbreak of infectious diseases. ThePortfolio’s investment in any country could be subjectto governmental actions such as capital or currencycontrols, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome. Foreign securities may also be more difficult toresell than comparable U.S. securities because themarkets for foreign securities are often less liquid. Evenwhen a foreign security increases in price in its localcurrency, the appreciation may be diluted by adversechanges in exchange rates when the security’s value isconverted to U.S. dollars. Foreign withholding taxes alsomay apply and errors and delays may occur in thesettlement process for foreign securities.

Emerging Markets Risk. The economic and politicalstructures of developing countries in emerging markets,in most cases, do not compare favorably with the U.S.or other developed countries in terms of wealth andstability, and their financial markets often lack liquidity.Portfolio performance will likely be negatively affectedby portfolio exposure to countries and corporationsdomiciled in or with revenue exposures to countries inthe midst of, among other things, hyperinflation,currency devaluation, trade disagreements, suddenpolitical upheaval, or interventionist governmentpolicies. Portfolio performance may also be negativelyaffected by portfolio exposure to countries andcorporations domiciled in or with revenue exposures tocountries with less developed legal, tax, regulatory, andaccounting systems. Significant buying or selling actionsby a few major investors may also heighten thevolatility of emerging markets. These factors makeinvesting in emerging market countries significantlyriskier than in other countries, and events in any onecountry could cause the Portfolio’s share price todecline.

Foreign Currency Risk. The value of a foreigncurrency may decline against the U.S. dollar, whichwould reduce the dollar value of securities denominatedin that currency. The overall impact of such a decline offoreign currency can be significant, unpredictable, andlong lasting, depending on the currencies represented,how each one appreciates or depreciates in relation tothe U.S. dollar, and whether currency positions arehedged. Under normal conditions, the Portfolio doesnot engage in extensive foreign currency hedgingprograms. Further, exchange rate movements arevolatile, and it is not possible to effectively hedge thecurrency risks of many developing countries.

Small Cap Risk. Smaller, less seasoned companiesoften have greater price volatility, lower trading volume,and less liquidity than larger, more establishedcompanies. These companies tend to have small

revenues, narrower product lines, less managementdepth and experience, small shares of their product orservice markets, fewer financial resources, and lesscompetitive strength than larger companies. Suchcompanies seldom pay significant dividends that couldsoften the impact of a falling market on returns.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

Value Investing Risk. Value style investing includesthe risk that stocks of undervalued companies may notrise as quickly as anticipated if the market doesn’trecognize their intrinsic value or if value stocks are outof favor.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets. There is also no guarantee thatthe Adviser will be able to effectively implement thePortfolio’s investment objective.

Conflicts of Interest Risk. An investment in thePortfolio will be subject to a number of actual orpotential conflicts of interest.For example, the Adviseror its affiliates may provide services to the Portfolio forwhich the Portfolio would compensate the Adviserand/or such affiliates. The Portfolio may invest in otherpooled investment vehicles sponsored, managed, orotherwise affiliated with the Adviser, including otherPortfolios. The Adviser may have an incentive (financialor otherwise) to enter into transactions or arrangementson behalf of the Portfolio with itself or its affiliates incircumstances where it might not have done sootherwise.

The Adviser or its affiliates manage other investmentfunds and/or accounts (including proprietary accounts)and have other clients with investment objectives andstrategies that are similar to, or overlap with, theinvestment objective and strategy of the Portfolio,creating conflicts of interest in investment andallocation decisions regarding the allocation ofinvestments that could be appropriate for the Portfolioand other clients of the Adviser or their affiliates.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Quantitative Investing Risk. Quantitative InvestingRisk is the risk that securities selected according to aquantitative analysis methodology can performdifferently from the market as a whole based on themodel and the factors used in the analysis, the weightplaced on each factor and changes in the factor’shistorical trends. Such models are based on assumptionsof these and other market factors, and the models maynot take into account certain factors, or perform asintended, and may result in a decline in the value of thePortfolio’s portfolio.

Derivatives Risk. The use of derivatives (such asfutures) involves additional risks and transaction costswhich could leave the Portfolio in a worse position thanif it had not used these instruments. The Portfolioutilizes equity futures in order to increase or decrease itsexposure to various asset classes at a lower cost thantrading stocks directly. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is the riskthat the other party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

1 The Adviser has contractually agreed, for as long as the current feestructure is in place and through at least April 30, 2021, to waive anamount equal to any management fees indirectly incurred by thePortfolio as a result of its investment in any other mutual fund forwhich the Adviser or an affiliate serves as investment adviser, otherthan Thrivent Cash Management Trust.

The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods. Inaddition, the example for the 1 Year period reflects theeffect of the contractual fee waiver and/or expense

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 93% ofthe average value of its portfolio.

Principal StrategiesThe Portfolio pursues its objective by investing in acombination of other funds managed by the Adviser oran affiliate and directly held financial instruments. ThePortfolio is designed for investors who seek moderatelygreater long-term capital growth and are comfortablewith moderately higher levels of risk and volatility. ThePortfolio uses a prescribed asset allocation strategyinvolving a two-step process that is designed to achieveits desired risk tolerance. The first step is theconstruction of a model for the allocation of thePortfolio’s assets across broad asset categories (namely,equity securities and debt securities). The second stepinvolves the determination of sub-classes within thebroad asset categories and target weightings (i.e., whatthe Adviser determines is the strategic allocation) forthese sub-classes. Sub-classes for equity securities may bebased on market capitalization, investment style (suchas growth or value), or economic sector. Sub-classes fordebt securities may be based on maturity, duration,security type or credit rating (high yield—commonlyknown as “junk bonds”—or investment grade).

The use of target weightings for various sub-classeswithin broad asset categories is intended as a multi-styleapproach to reduce the risk of investing in securitieshaving common characteristics. The Portfolio may buyand sell futures contracts to either hedge its exposure orobtain exposure to certain investments.

The Portfolio may invest in foreign securities, includingthose of issuers in emerging markets. An “emerging

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. Therefore, a principal risk of investing in thePortfolio is that the allocation strategies used and theallocation decisions made will not produce the desiredresults.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Small Cap Risk. Smaller, less seasoned companiesoften have greater price volatility, lower trading volume,and less liquidity than larger, more establishedcompanies. These companies tend to have smallrevenues, narrower product lines, less managementdepth and experience, small shares of their product orservice markets, fewer financial resources, and lesscompetitive strength than larger companies. Suchcompanies seldom pay significant dividends that couldsoften the impact of a falling market on returns.

Mid Cap Risk. Medium-sized companies often havegreater price volatility, lower trading volume, and lessliquidity than larger, more-established companies. Thesecompanies tend to have smaller revenues, narrowerproduct lines, less management depth and experience,smaller shares of their product or service markets, fewerfinancial resources, and less competitive strength thanlarger companies.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Other Funds Risk. Because the Portfolio invests inother funds managed by the Adviser or an affiliate(“Other Funds”), the performance of the Portfolio isdependent, in part, upon the performance of OtherFunds in which the Portfolio may invest. As a result, thePortfolio is subject to the same risks as those faced bythe Other Funds. In addition, Other Funds may besubject to additional fees and expenses that will beborne by the Portfolio.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

Value Investing Risk. Value style investing includesthe risk that stocks of undervalued companies may notrise as quickly as anticipated if the market doesn’trecognize their intrinsic value or if value stocks are outof favor.

Foreign Securities Risk. Foreign securities generallycarry more risk and are more volatile than theirdomestic counterparts, in part because of potential forhigher political and economic risks, lack of reliableinformation and fluctuations in currency exchange rateswhere investments are denominated in currencies otherthan the U.S. dollar. Certain events in foreign marketsmay adversely affect foreign and domestic issuers,including interruptions in the global supply chain,natural disasters and outbreak of infectious diseases. ThePortfolio’s investment in any country could be subjectto governmental actions such as capital or currencycontrols, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome. Foreign securities may also be more difficult toresell than comparable U.S. securities because themarkets for foreign securities are often less liquid. Evenwhen a foreign security increases in price in its localcurrency, the appreciation may be diluted by adversechanges in exchange rates when the security’s value isconverted to U.S. dollars. Foreign withholding taxes alsomay apply and errors and delays may occur in thesettlement process for foreign securities.

Emerging Markets Risk. The economic and politicalstructures of developing countries in emerging markets,in most cases, do not compare favorably with the U.S.or other developed countries in terms of wealth andstability, and their financial markets often lack liquidity.Portfolio performance will likely be negatively affectedby portfolio exposure to countries and corporationsdomiciled in or with revenue exposures to countries inthe midst of, among other things, hyperinflation,currency devaluation, trade disagreements, suddenpolitical upheaval, or interventionist governmentpolicies. Portfolio performance may also be negativelyaffected by portfolio exposure to countries andcorporations domiciled in or with revenue exposures tocountries with less developed legal, tax, regulatory, andaccounting systems. Significant buying or selling actionsby a few major investors may also heighten thevolatility of emerging markets. These factors makeinvesting in emerging market countries significantlyriskier than in other countries, and events in any onecountry could cause the Portfolio’s share price todecline.

Foreign Currency Risk. The value of a foreigncurrency may decline against the U.S. dollar, whichwould reduce the dollar value of securities denominatedin that currency. The overall impact of such a decline offoreign currency can be significant, unpredictable, andlong lasting, depending on the currencies represented,how each one appreciates or depreciates in relation tothe U.S. dollar, and whether currency positions arehedged. Under normal conditions, the Portfolio doesnot engage in extensive foreign currency hedgingprograms. Further, exchange rate movements arevolatile, and it is not possible to effectively hedge thecurrency risks of many developing countries.Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Changes by the Federal Reserve tomonetary policies could affect interest rates and thevalue of some securities. In addition, the phase out ofLIBOR (the offered rate for short-term Eurodollardeposits between major international banks) by the endof 2021 could lead to increased volatility and illiquidityin certain markets that currently rely on LIBOR todetermine interest rates.Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategy

depends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets. There is also no guarantee thatthe Adviser will be able to effectively implement thePortfolio’s investment objective.Conflicts of Interest Risk. An investment in thePortfolio will be subject to a number of actual orpotential conflicts of interest.For example, the Adviseror its affiliates may provide services to the Portfolio forwhich the Portfolio would compensate the Adviserand/or such affiliates. The Portfolio may invest in otherpooled investment vehicles sponsored, managed, orotherwise affiliated with the Adviser, including otherPortfolios. The Adviser may have an incentive (financialor otherwise) to enter into transactions or arrangementson behalf of the Portfolio with itself or its affiliates incircumstances where it might not have done sootherwise.The Adviser or its affiliates manage other investmentfunds and/or accounts (including proprietary accounts)and have other clients with investment objectives andstrategies that are similar to, or overlap with, theinvestment objective and strategy of the Portfolio,creating conflicts of interest in investment andallocation decisions regarding the allocation ofinvestments that could be appropriate for the Portfolioand other clients of the Adviser or their affiliates.Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.Quantitative Investing Risk. Quantitative InvestingRisk is the risk that securities selected according to aquantitative analysis methodology can performdifferently from the market as a whole based on themodel and the factors used in the analysis, the weightplaced on each factor and changes in the factor’shistorical trends. Such models are based on assumptionsof these and other market factors, and the models maynot take into account certain factors, or perform asintended, and may result in a decline in the value of thePortfolio’s portfolio.Derivatives Risk. The use of derivatives (such asfutures) involves additional risks and transaction costswhich could leave the Portfolio in a worse position thanif it had not used these instruments. The Portfolioutilizes equity futures in order to increase or decrease itsexposure to various asset classes at a lower cost thantrading stocks directly.

Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is the risk

that the other party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a % of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the lower of the original purchaseprice or current net asset value) N/A

ANNUAL PORTFOLIO OPERATING EXPENSES(expenses that you pay each year as a percentage ofthe value of your investment)

Management Fees 0.56%

Other Expenses 0.03%

Total Annual Portfolio Operating Expenses 0.73%

Less Fee Waivers and/or ExpenseReimbursements1 0.13%

Total Annual Portfolio Operating Expenses AfterFee Waivers and/or Expense Reimbursements 0.60%

1 The Adviser has contractually agreed, for as long as the current feestructure is in place and through at least April 30, 2021, to waive anamount equal to any management fees indirectly incurred by thePortfolio as a result of its investment in any other mutual fund forwhich the Adviser or an affiliate serves as investment adviser, otherthan Thrivent Cash Management Trust. This contractual provisionmay be terminated upon the mutual agreement between theIndependent Directors of the Portfolio and the Adviser.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods. Inaddition, the example for the 1 Year period reflects theeffect of the contractual fee waiver and/or expense

reimbursement. The example also assumes that yourinvestment has a 5% return each year, and that thePortfolio’s operating expenses remain the same.Although your actual cost may be higher or lower, basedon the foregoing assumptions, your cost would be:

Thrivent ModeratelyConservativeAllocation Portfolio $61 $220 $393 $894

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 179% ofthe average value of its portfolio.

Principal StrategiesThe Portfolio pursues its objective by investing in acombination of other funds managed by the Adviser oran affiliate and directly held financial instruments. ThePortfolio is designed for investors who seek long-termcapital growth with reasonable stability of principal andmore conservative levels of risk and volatility. ThePortfolio uses a prescribed asset allocation strategyinvolving a two-step process that is designed to achieveits desired risk tolerance. The first step is theconstruction of a model for the allocation of thePortfolio’s assets across broad asset categories (namely,debt securities and equity securities). The second stepinvolves the determination of sub-classes within thebroad asset categories and target weightings (i.e., whatthe Adviser determines is the strategic allocation) forthese sub-classes. Sub-classes for debt securities may bebased on maturity, duration, security type or creditrating (high yield—commonly known as “junkbonds”—or investment grade) and may includeleveraged loans, which are senior secured loans that aremade by banks or other lending institutions tocompanies that are rated below investment grade.Sub-classes for equity securities may be based on marketcapitalization, investment style (such as growth orvalue), or economic sector.

The use of target weightings for various sub-classeswithin broad asset categories is intended as a multi-styleapproach to reduce the risk of investing in securitieshaving common characteristics. The Portfolio may buy

and sell futures contracts to either hedge its exposure orobtain exposure to certain investments.

The Portfolio may invest in foreign securities, includingthose of issuers in emerging markets. An “emergingmarket” country is any country determined by theAdviser to have an emerging market economy,considering factors such as the country’s credit rating,its political and economic stability and the developmentof its financial and capital markets.

Under normal circumstances, the Portfolio invests inthe following broad asset classes within the rangesgiven:

The Portfolio’s actual holdings in each broad assetcategory may be outside the applicable allocation rangefrom time to time due to differing investmentperformance among asset categories. The Adviser willrebalance the Portfolio at least annually so that itsholdings are within the ranges for the broad assetcategories.

The Portfolio pursues its investment strategy byinvesting primarily in other mutual funds managed bythe Adviser or an affiliate. The names of the fundsmanaged by the Adviser or an affiliate which arecurrently available for investment by the Portfolio areshown in the list below.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. Therefore, a principal risk of investing in thePortfolio is that the allocation strategies used and theallocation decisions made will not produce the desiredresults.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Changes by the Federal Reserve tomonetary policies could affect interest rates and thevalue of some securities. In addition, the phase out ofLIBOR (the offered rate for short-term Eurodollardeposits between major international banks) by the endof 2021 could lead to increased volatility and illiquidityin certain markets that currently rely on LIBOR todetermine interest rates.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decrease

2

TSF-110

Page 165: THRIVENT FLEXIBLE PREMIUM DEFERRED VARIABLE ANNUITY · 2020-04-30 · THRIVENT VARIABLE ANNUITY ACCOUNT C THRIVENT SERIES FUND,INC. PROSPECTUS FOR FLEXIBLE PREMIUM DEFERRED VARIABLE

more than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Mortgage-Backed and Other Asset-BackedSecurities Risk. The value of mortgage-backed andasset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlyingsuch securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid. In addition, bothmortgage-backed and asset-backed securities aresensitive to changes in the repayment patterns of theunderlying security. If the principal payment on theunderlying asset is repaid faster or slower than theholder of the asset-backed or mortgage-backed securityanticipates, the price of the security may fall,particularly if the holder must reinvest the repaidprincipal at lower rates or must continue to hold thesecurity when interest rates rise. This effect may causethe value of the Portfolio to decline and reduce theoverall return of the Portfolio.

Government Securities Risk. The Portfolio invests insecurities issued or guaranteed by the U.S. governmentor its agencies and instrumentalities (such as FederalHome Loan Bank, Ginnie Mae, Fannie Mae or FreddieMac securities). Securities issued or guaranteed byFederal Home Loan Banks, Ginnie Mae, Fannie Mae orFreddie Mac are not issued directly by the U.S.government. Ginnie Mae is a wholly owned U.S.corporation that is authorized to guarantee, with thefull faith and credit of the U.S. government, the timelypayment of principal and interest of its securities. Bycontrast, securities issued or guaranteed by U.S.government-related organizations such as Federal HomeLoan Banks, Fannie Mae and Freddie Mac are notbacked by the full faith and credit of the U.S.government. No assurance can be given that the U.S.government would provide financial support to itsagencies and instrumentalities if not required to do soby law. In addition, the value of U.S. government

securities may be affected by changes in the credit ratingof the U.S. government.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected. High yield securities generally have a lessliquid resale market.

Mid Cap Risk. Medium-sized companies often havegreater price volatility, lower trading volume, and lessliquidity than larger, more-established companies. Thesecompanies tend to have smaller revenues, narrowerproduct lines, less management depth and experience,smaller shares of their product or service markets, fewerfinancial resources, and less competitive strength thanlarger companies.

Other Funds Risk. Because the Portfolio invests inother funds managed by the Adviser or an affiliate(“Other Funds”), the performance of the Portfolio isdependent, in part, upon the performance of OtherFunds in which the Portfolio may invest. As a result, thePortfolio is subject to the same risks as those faced bythe Other Funds. In addition, Other Funds may besubject to additional fees and expenses that will beborne by the Portfolio.

Foreign Securities Risk. Foreign securities generallycarry more risk and are more volatile than theirdomestic counterparts, in part because of potential forhigher political and economic risks, lack of reliableinformation and fluctuations in currency exchange rateswhere investments are denominated in currencies otherthan the U.S. dollar. Certain events in foreign marketsmay adversely affect foreign and domestic issuers,including interruptions in the global supply chain,natural disasters and outbreak of infectious diseases. ThePortfolio’s investment in any country could be subjectto governmental actions such as capital or currencycontrols, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome. Foreign securities may also be more difficult toresell than comparable U.S. securities because themarkets for foreign securities are often less liquid. Evenwhen a foreign security increases in price in its localcurrency, the appreciation may be diluted by adversechanges in exchange rates when the security’s value isconverted to U.S. dollars. Foreign withholding taxes alsomay apply and errors and delays may occur in thesettlement process for foreign securities.

Emerging Markets Risk. The economic and politicalstructures of developing countries in emerging markets,in most cases, do not compare favorably with the U.S.

TSF-111

or other developed countries in terms of wealth andstability, and their financial markets often lack liquidity.Portfolio performance will likely be negatively affectedby portfolio exposure to countries and corporationsdomiciled in or with revenue exposures to countries inthe midst of, among other things, hyperinflation,currency devaluation, trade disagreements, suddenpolitical upheaval, or interventionist governmentpolicies. Portfolio performance may also be negativelyaffected by portfolio exposure to countries andcorporations domiciled in or with revenue exposures tocountries with less developed legal, tax, regulatory, andaccounting systems. Significant buying or selling actionsby a few major investors may also heighten thevolatility of emerging markets. These factors makeinvesting in emerging market countries significantlyriskier than in other countries, and events in any onecountry could cause the Portfolio’s share price todecline.

Foreign Currency Risk. The value of a foreigncurrency may decline against the U.S. dollar, whichwould reduce the dollar value of securities denominatedin that currency. The overall impact of such a decline offoreign currency can be significant, unpredictable, andlong lasting, depending on the currencies represented,how each one appreciates or depreciates in relation tothe U.S. dollar, and whether currency positions arehedged. Under normal conditions, the Portfolio doesnot engage in extensive foreign currency hedgingprograms. Further, exchange rate movements arevolatile, and it is not possible to effectively hedge thecurrency risks of many developing countries.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets. There is also no guarantee thatthe Adviser will be able to effectively implement thePortfolio’s investment objective.

Conflicts of Interest Risk. An investment in thePortfolio will be subject to a number of actual orpotential conflicts of interest.For example, the Adviseror its affiliates may provide services to the Portfolio forwhich the Portfolio would compensate the Adviserand/or such affiliates. The Portfolio may invest in otherpooled investment vehicles sponsored, managed, orotherwise affiliated with the Adviser, including otherPortfolios. The Adviser may have an incentive (financialor otherwise) to enter into transactions or arrangementson behalf of the Portfolio with itself or its affiliates incircumstances where it might not have done sootherwise.

The Adviser or its affiliates manage other investmentfunds and/or accounts (including proprietary accounts)

and have other clients with investment objectives andstrategies that are similar to, or overlap with, theinvestment objective and strategy of the Portfolio,creating conflicts of interest in investment andallocation decisions regarding the allocation ofinvestments that could be appropriate for the Portfolioand other clients of the Adviser or their affiliates.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Quantitative Investing Risk. Quantitative InvestingRisk is the risk that securities selected according to aquantitative analysis methodology can performdifferently from the market as a whole based on themodel and the factors used in the analysis, the weightplaced on each factor and changes in the factor’shistorical trends. Such models are based on assumptionsof these and other market factors, and the models maynot take into account certain factors, or perform asintended, and may result in a decline in the value of thePortfolio’s portfolio.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Prepayment Risk. When interest rates fall, certainobligations will be paid off by the obligor more quicklythan originally anticipated, and a Portfolio may have toinvest the proceeds in securities with lower yields. Inperiods of falling interest rates, the rate of prepaymentstends to increase (as does price fluctuation) as borrowersare motivated to pay off debt and refinance at newlower rates. During such periods, reinvestment of theprepayment proceeds by the management team willgenerally be at lower rates of return than the return on

the assets that were prepaid. Prepayment generallyreduces the yield to maturity and the average life of thesecurity.

Derivatives Risk. The use of derivatives (such asfutures) involves additional risks and transaction costswhich could leave the Portfolio in a worse position thanif it had not used these instruments. The Portfolioutilizes equity futures in order to increase or decrease itsexposure to various asset classes at a lower cost thantrading stocks directly. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is the riskthat the other party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

Government securitiesare any securities issued or guaranteed as to principal orinterest by the United States, or by a person controlledor supervised by and acting as an instrumentality of thegovernment of the United States pursuant to authoritygranted by the Congress of the United States; or anycertificate of deposit for any of the foregoing.

The Adviser manages the Portfolio subject to strict rulesestablished by the Securities and Exchange Commissionthat are designed so that the Portfolio may maintain astable $1.00 share price. Those rules generally requirethe Portfolio, among other things, to invest only inhigh quality securities that are denominated in U.S.dollars and have short remaining maturities. Inaddition, the rules require the Portfolio to maintain adollar-weighted average maturity (WAM) of not morethan 60 days and a dollar-weighted average life (WAL) ofnot more than 120 days. When calculating its WAM, thePortfolio may shorten its maturity by using the interestrate resets of certain adjustable rate securities. Generally,the Portfolio may not take into account these resetswhen calculating its WAL.

The Adviser typically uses U.S. Treasury securities,short-term discount notes issued by government-relatedorganizations and government securities payable withinseven-days or less to provide liquidity for reasonablyforeseeable shareholder redemptions and to complywith regulatory requirements. The Adviser invests inother securities by selecting from the available supply ofshort-term government securities based on its interestrate outlook and analysis of quantitative and technicalfactors. Although the Portfolio frequently holdssecurities until maturity, the Adviser may sell securitiesto increase liquidity. The Adviser will select securities forsuch sales based on how close the sale price would be totheir amortized costs.

Principal RisksYou could lose money by investing in the Portfolio.Although the Portfolio seeks to preserve the value ofyour investment at $1.00 per share, it cannot guaranteeit will do so. An investment in the Portfolio is notinsured or guaranteed by the Federal Deposit InsuranceCorporation or any other government agency. ThePortfolio’s sponsor has no legal obligation to providefinancial support to the Portfolio, and you should notexpect that the sponsor will provide financial support to

the Portfolio at any time. In addition, the Portfolio issubject to the following principal investment risks.

Government Securities Risk. The Portfolio invests insecurities issued or guaranteed by the U.S. governmentor its agencies and instrumentalities (such as FederalHome Loan Bank, Ginnie Mae, Fannie Mae or FreddieMac securities). Securities issued or guaranteed byFederal Home Loan Banks, Ginnie Mae, Fannie Mae orFreddie Mac are not issued directly by the U.S.government. Ginnie Mae is a wholly owned U.S.corporation that is authorized to guarantee, with thefull faith and credit of the U.S. government, the timelypayment of principal and interest of its securities. Bycontrast, securities issued or guaranteed by U.S.government-related organizations such as Federal HomeLoan Banks, Fannie Mae and Freddie Mac are notbacked by the full faith and credit of the U.S.government. No assurance can be given that the U.S.government would provide financial support to itsagencies and instrumentalities if not required to do soby law. In addition, the value of U.S. governmentsecurities may be affected by changes in the credit ratingof the U.S. government.

Interest Rate Risk. A weak economy, strong equitymarkets, or changes by the Federal Reserve in itsmonetary policies may cause short-term interest rates toincrease and affect the Portfolio’s ability to maintain astable share price.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Redemption Risk. The Portfolio may need to sellportfolio securities to meet redemption requests. ThePortfolio could experience a loss when selling portfoliosecurities to meet redemption requests if there is (i)significant redemption activity by shareholders,including, for example, when a single investor or fewlarge investors make a significant redemption ofPortfolio shares, (ii) a disruption in the normaloperation of the markets in which the Portfolio buysand sells portfolio securities or (iii) the inability of thePortfolio to sell portfolio securities because suchsecurities are illiquid. In such events, the Portfolio couldbe forced to sell portfolio securities at unfavorable pricesin an effort to generate sufficient cash to pay redeemingshareholders. Although the Portfolio generally does nothave the ability to impose liquidity fees or temporarilysuspend redemptions, the payment of redemptionproceeds could be delayed or denied if the Portfolio isliquidated, to the extent permitted by applicableregulations.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resulted

in substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

Thrivent Multidimensional Income PortfolioInvestment ObjectiveThrivent Multidimensional Income Portfolio (the�Portfolio�) seeks a high level of current income and,secondarily, growth of capital. The Portfolio’sinvestment objectives may be changed withoutshareholder approval.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a % of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the lower of the original purchaseprice or current net asset value) N/A

Total Annual Portfolio Operating Expenses 1.72%

Less Fee Waivers and/or ExpenseReimbursements1 0.47%

Total Annual Portfolio Operating Expenses AfterFee Waivers and/or Expense Reimbursements 1.25%

1 The Adviser has contractually agreed, through at least April 30,2021, to waive a portion of the management fees associated withthe shares of the Thrivent Multidimensional Income Portfolio inorder to limit the Total Annual Portfolio Operating Expenses AfterFee Waivers and/or Expense Reimbursements to an annual rate of0.95% of the average daily net assets of the shares. This contractualprovision, however, may be terminated before the indicatedtermination date upon the mutual agreement between theIndependent Directors of the Portfolio and the Adviser.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and then

redeem all of your shares at the end of those periods. Inaddition, the example for the 1 Year period reflects theeffect of the contractual fee waiver and/or expensereimbursement. The example also assumes that yourinvestment has a 5% return each year, and that thePortfolio’s operating expenses remain the same.Although your actual cost may be higher or lower, basedon the foregoing assumptions, your cost would be:

ThriventMultidimensionalIncome Portfolio $127 $496 $889 $1,991

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 106% ofthe average value of its portfolio.

Principal StrategiesThe Portfolio seeks to achieve its investment objectivesby allocating assets across multiple income and growthproducing asset classes and strategies. Debt securities inwhich the Portfolio invests include high yield, high riskbonds, notes, debentures and other debt obligationscommonly known as “junk bonds.” At the time ofpurchase, these high-yield securities are rated within orbelow the “BB” major rating category by S&P or the“Ba” major rating category by Moody’s or are unratedbut considered to be of comparable quality by theAdviser. The Portfolio will also implement itsinvestment strategy by investing in convertible bondsand U.S. dollar denominated emerging marketssovereign debt.

The Portfolio also plans to invest in income-producingequity securities, including preferred stock and realestate investment trusts (“REITs”). The Portfolio willinvest in other income-producing securities such asshares of closed-end funds (“CEFs”), publicly-tradedbusiness development companies (“BDCs”), masterlimited partnerships (“MLPs”), and exchange-tradedfunds (“ETFs”). CEFs are investment companies thatissue a fixed number of shares that trade on a stockexchange or over-the-counter, typically at a premium ora discount to their net asset value. BDCs are publiclyheld investment funds that invest primarily in private

and thinly traded public U.S. businesses. MLPs arepublicly-traded limited partnerships that are limited bythe Internal Revenue Code to only apply to enterprisesthat engage in certain businesses, mostly pertaining tothe use of natural resources. ETFs are investmentcompanies generally designed to track the performanceof a securities or other index or benchmark. ThePortfolio may also pursue its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate and unaffiliatedfunds.

The Portfolio may invest in other securities such asinvestment-grade corporate bonds, asset-backedsecurities, mortgage-backed securities (includingcommercially backed ones), and leveraged loans. ThePortfolio utilizes derivatives primarily in the form ofU.S. Treasury futures contracts in order to manage thePortfolio’s duration, or interest rate risk. The Portfoliomay enter into derivatives contracts traded onexchanges or in the over the counter market.

The Adviser uses fundamental, quantitative andtechnical investment research techniques to determinewhat to buy and sell. Fundamental techniques assess asecurity’s value based on an issuer’s financial profile,management, and business prospects while quantitativeand technical techniques involve a more data-orientedanalysis of financial information, market trends andprice movements.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Changes by the Federal Reserve tomonetary policies could affect interest rates and thevalue of some securities. In addition, the phase out ofLIBOR (the offered rate for short-term Eurodollardeposits between major international banks) by the endof 2021 could lead to increased volatility and illiquidityin certain markets that currently rely on LIBOR todetermine interest rates.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result of

such an event, the debt security may decline in priceand affect the value of the Portfolio.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected. High yield securities generally have a lessliquid resale market.

Preferred Securities Risk. There are certainadditional risks associated with investing in preferredsecurities, including, but not limited to, preferredsecurities may include provisions that permit the issuer,at its discretion, to defer or omit distributions for astated period without any adverse consequences to theissuer; preferred securities are generally subordinated tobonds and other debt instruments in a company’scapital structure in terms of having priority to corporateincome and liquidation payments, and therefore will besubject to greater credit risk than more senior debtinstruments; preferred securities may be substantiallyless liquid than many other securities, such as commonstocks or U.S. Government securities; generally,traditional preferred securities offer no voting rightswith respect to the issuing company unless preferreddividends have been in arrears for a specified number ofperiods, at which time the preferred security holdersmay elect a number of directors to the issuer’s board;and in certain varying circumstances, an issuer ofpreferred securities may redeem the securities prior to aspecified date.

Closed-End Fund (“CEF”) Risk. Investments in CEFsare subject to various risks, including reliance onmanagement’s ability to meet a CEF’s investmentobjective and to manage a CEF’s portfolio; fluctuation inthe market value of a CEF’s shares compared to thechanges in the value of the underlying securities thatthe CEF owns (i.e., trading at a discount or premium toits net asset value); and that CEFs are permitted toinvest in a greater amount of “illiquid” securities thantypical mutual funds. The Portfolio is subject to apro-rata share of the management fees and expenses ofeach CEF in addition to the Portfolio’s management feesand expenses, resulting in Portfolio shareholders subjectto higher expenses than if they invested directly inCEFs.

Emerging Markets Risk. The economic and politicalstructures of developing countries in emerging markets,in most cases, do not compare favorably with the U.S.or other developed countries in terms of wealth andstability, and their financial markets often lack liquidity.Portfolio performance will likely be negatively affectedby portfolio exposure to countries and corporationsdomiciled in or with revenue exposures to countries in

2

TSF-121

Page 176: THRIVENT FLEXIBLE PREMIUM DEFERRED VARIABLE ANNUITY · 2020-04-30 · THRIVENT VARIABLE ANNUITY ACCOUNT C THRIVENT SERIES FUND,INC. PROSPECTUS FOR FLEXIBLE PREMIUM DEFERRED VARIABLE

the midst of, among other things, hyperinflation,currency devaluation, trade disagreements, suddenpolitical upheaval, or interventionist governmentpolicies. Portfolio performance may also be negativelyaffected by portfolio exposure to countries andcorporations domiciled in or with revenue exposures tocountries with less developed legal, tax, regulatory, andaccounting systems. Significant buying or selling actionsby a few major investors may also heighten thevolatility of emerging markets. These factors makeinvesting in emerging market countries significantlyriskier than in other countries, and events in any onecountry could cause the Portfolio’s share price todecline.

Foreign Securities Risk. Foreign securities generallycarry more risk and are more volatile than theirdomestic counterparts, in part because of potential forhigher political and economic risks, lack of reliableinformation and fluctuations in currency exchange rateswhere investments are denominated in currencies otherthan the U.S. dollar. Certain events in foreign marketsmay adversely affect foreign and domestic issuers,including interruptions in the global supply chain,natural disasters and outbreak of infectious diseases. ThePortfolio’s investment in any country could be subjectto governmental actions such as capital or currencycontrols, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome. Foreign securities may also be more difficult toresell than comparable U.S. securities because themarkets for foreign securities are often less liquid. Evenwhen a foreign security increases in price in its localcurrency, the appreciation may be diluted by adversechanges in exchange rates when the security’s value isconverted to U.S. dollars. Foreign withholding taxes alsomay apply and errors and delays may occur in thesettlement process for foreign securities.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Mortgage-Backed and Other Asset-BackedSecurities Risk. The value of mortgage-backed andasset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlyingsuch securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,

mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid. In addition, bothmortgage-backed and asset-backed securities aresensitive to changes in the repayment patterns of theunderlying security. If the principal payment on theunderlying asset is repaid faster or slower than theholder of the asset-backed or mortgage-backed securityanticipates, the price of the security may fall,particularly if the holder must reinvest the repaidprincipal at lower rates or must continue to hold thesecurity when interest rates rise. This effect may causethe value of the Portfolio to decline and reduce theoverall return of the Portfolio.

Convertible Securities Risk. Convertible securities aresubject to the usual risks associated with debt securities,such as interest rate risk and credit risk. Convertiblesecurities also react to changes in the value of thecommon stock into which they convert, and are thussubject to market risk. The Portfolio may also be forcedto convert a convertible security at an inopportunetime, which may decrease the Portfolio’s return.

Government Securities Risk. The Portfolio invests insecurities issued or guaranteed by the U.S. governmentor its agencies and instrumentalities (such as FederalHome Loan Bank, Ginnie Mae, Fannie Mae or FreddieMac securities). Securities issued or guaranteed byFederal Home Loan Banks, Ginnie Mae, Fannie Mae orFreddie Mac are not issued directly by the U.S.government. Ginnie Mae is a wholly owned U.S.corporation that is authorized to guarantee, with thefull faith and credit of the U.S. government, the timelypayment of principal and interest of its securities. Bycontrast, securities issued or guaranteed by U.S.government-related organizations such as Federal HomeLoan Banks, Fannie Mae and Freddie Mac are notbacked by the full faith and credit of the U.S.government. No assurance can be given that the U.S.government would provide financial support to itsagencies and instrumentalities if not required to do soby law. In addition, the value of U.S. governmentsecurities may be affected by changes in the credit ratingof the U.S. government.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets. There is also no guarantee thatthe Adviser will be able to effectively implement thePortfolio’s investment objective.

Page 177: THRIVENT FLEXIBLE PREMIUM DEFERRED VARIABLE ANNUITY · 2020-04-30 · THRIVENT VARIABLE ANNUITY ACCOUNT C THRIVENT SERIES FUND,INC. PROSPECTUS FOR FLEXIBLE PREMIUM DEFERRED VARIABLE

Conflicts of Interest Risk. An investment in thePortfolio will be subject to a number of actual orpotential conflicts of interest.For example, the Adviseror its affiliates may provide services to the Portfolio forwhich the Portfolio would compensate the Adviserand/or such affiliates. The Portfolio may invest in otherpooled investment vehicles sponsored, managed, orotherwise affiliated with the Adviser, including otherPortfolios. The Adviser may have an incentive (financialor otherwise) to enter into transactions or arrangementson behalf of the Portfolio with itself or its affiliates incircumstances where it might not have done sootherwise.

The Adviser or its affiliates manage other investmentfunds and/or accounts (including proprietary accounts)and have other clients with investment objectives andstrategies that are similar to, or overlap with, theinvestment objective and strategy of the Portfolio,creating conflicts of interest in investment andallocation decisions regarding the allocation ofinvestments that could be appropriate for the Portfolioand other clients of the Adviser or their affiliates.

Sovereign Debt Risk. Sovereign debt securities areissued or guaranteed by foreign governmental entities.These investments are subject to the risk that agovernmental entity may delay or refuse to pay interestor repay principal on its sovereign debt, due, forexample, to cash flow problems, insufficient foreigncurrency reserves, political considerations, the relativesize of the governmental entity’s debt position inrelation to the economy or the failure to put in placeeconomic reforms required by the InternationalMonetary Fund or other multilateral agencies. If agovernmental entity defaults, it may ask for more timein which to pay or for further loans. There is no legalprocess for collecting sovereign debts that a governmentdoes not pay nor are there bankruptcy proceedingsthrough which all or part of the sovereign debt that agovernmental entity has not repaid may be collected.

Business Development Company (“BDC”) Risk.The value of a BDC’s investments will be affected byportfolio company specific performance as well as theoverall economic environment. Shares of BDCs maytrade at prices that reflect a premium above or adiscount below the investment company’s net assetvalue, which may be substantial. The Portfolio may beexposed to greater risk and experience higher volatilitythan would a portfolio that was not invested in BDCs.Additionally, most BDCs employ leverage which canmagnify the returns of underlying investments.

Investment in Other Investment Companies Risk.Investing in other investment companies, includingCEFs and BDCs, could result in the duplication ofcertain fees, including management and administrativefees, and may expose the Portfolio to the risks of

owning the underlying investments that the otherinvestment company holds.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Dealer inventories ofbonds are at or near historic lows in relation to marketsize, which has the potential to decrease liquidity andincrease price volatility in the fixed income markets,particularly during periods of economic or market stress.As a result of this decreased liquidity, the Portfolio mayhave to accept a lower price to sell a security, sell othersecurities to raise cash, or give up an investmentopportunity, any of which could have a negative effecton performance.

Derivatives Risk. The use of derivatives (such asfutures) involves additional risks and transaction costswhich could leave the Portfolio in a worse position thanif it had not used these instruments. The Portfolioutilizes futures on U.S. Treasuries in order to manageduration. The use of derivatives can lead to lossesbecause of adverse movements in the price or value ofthe underlying asset, index or rate, which may bemagnified by certain features of the contract. Changesin the value of the derivative may not correlate asintended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is the riskthat the other party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Other Funds Risk. Because the Portfolio invests inother funds managed by the Adviser or an affiliate(“Other Funds”), the performance of the Portfolio isdependent, in part, upon the performance of OtherFunds in which the Portfolio may invest. As a result, thePortfolio is subject to the same risks as those faced bythe Other Funds. In addition, Other Funds may besubject to additional fees and expenses that will beborne by the Portfolio.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of the

Thrivent Opportunity Income Plus PortfolioInvestment ObjectiveThrivent Opportunity Income Plus Portfolio (the�Portfolio�) seeks a combination of current income andlong-term capital appreciation.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a % of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the lower of the original purchaseprice or current net asset value) N/A

ANNUAL PORTFOLIO OPERATING EXPENSES(expenses that you pay each year as a percentage ofthe value of your investment)

Management Fees 0.50%

Other Expenses 0.13%

Acquired Fund Fees and Expenses 0.02%

Total Annual Portfolio Operating Expenses 0.65%

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods.The example also assumes that your investment has a5% return each year, and that the Portfolio’s operatingexpenses remain the same. Although your actual costmay be higher or lower, based on the foregoingassumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent OpportunityIncome Plus Portfolio $66 $208 $362 $810

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 195% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio primarilyinvests in a broad range of debt securities.

The debt securities in which the Portfolio invests maybe of any maturity or credit quality, including highyield, high risk bonds, notes, debentures and other debtobligations commonly known as “junk bonds.” At thetime of purchase, these high-yield securities are ratedwithin or below the “BB” major rating category by S&Por the “Ba” major rating category by Moody’s or areunrated but considered to be of comparable quality bythe Adviser. The Portfolio may also invest in leveragedloans, which are senior secured loans that are made bybanks or other lending institutions to companies thatare rated below investment grade. The Portfolio mayalso invest in investment-grade corporate bonds,asset-backed securities, mortgage-backed securities(including commercially backed ones), sovereign andemerging market debt (both U.S. dollar and non-U.S.dollar denominated), preferred stock, and other types ofsecurities.

The Portfolio utilizes derivatives primarily in the formof U.S. Treasury futures contracts in order to manage thePortfolio’s duration, or interest rate risk. The Portfoliomay enter into derivatives contracts traded onexchanges or in the over the counter market.

The Portfolio may invest in foreign securities, includingthose of issuers in emerging markets. An “emergingmarket” country is any country determined by theAdviser to have an emerging market economy,considering factors such as the country’s credit rating,its political and economic stability and the developmentof its financial and capital markets.

The Portfolio may invest in exchange-traded funds(“ETFs”), which are investment companies generallydesigned to track the performance of a securities orother index or benchmark.

The Portfolio may also pursue its investment strategy byinvesting in other mutual funds managed by theAdviser or an affiliate.

The Adviser uses fundamental, quantitative andtechnical investment research techniques to determinewhat to buy and sell. Fundamental techniques assess asecurity’s value based on an issuer’s financial profile,management, and business prospects while quantitativeand technical techniques involve a more data-orientedanalysis of financial information, market trends andprice movements.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Changes by the Federal Reserve tomonetary policies could affect interest rates and thevalue of some securities. In addition, the phase out ofLIBOR (the offered rate for short-term Eurodollardeposits between major international banks) by the endof 2021 could lead to increased volatility and illiquidityin certain markets that currently rely on LIBOR todetermine interest rates.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Mortgage-Backed and Other Asset-BackedSecurities Risk. The value of mortgage-backed andasset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlyingsuch securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid. In addition, bothmortgage-backed and asset-backed securities aresensitive to changes in the repayment patterns of theunderlying security. If the principal payment on theunderlying asset is repaid faster or slower than theholder of the asset-backed or mortgage-backed securityanticipates, the price of the security may fall,particularly if the holder must reinvest the repaidprincipal at lower rates or must continue to hold thesecurity when interest rates rise. This effect may cause

the value of the Portfolio to decline and reduce theoverall return of the Portfolio.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Prepayment Risk. When interest rates fall, certainobligations will be paid off by the obligor more quicklythan originally anticipated, and a Portfolio may have toinvest the proceeds in securities with lower yields. Inperiods of falling interest rates, the rate of prepaymentstends to increase (as does price fluctuation) as borrowersare motivated to pay off debt and refinance at newlower rates. During such periods, reinvestment of theprepayment proceeds by the management team willgenerally be at lower rates of return than the return onthe assets that were prepaid. Prepayment generallyreduces the yield to maturity and the average life of thesecurity.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected. High yield securities generally have a lessliquid resale market.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. Therefore, a principal risk of investing in thePortfolio is that the allocation strategies used and theallocation decisions made will not produce the desiredresults.

Foreign Securities Risk. Foreign securities generallycarry more risk and are more volatile than theirdomestic counterparts, in part because of potential forhigher political and economic risks, lack of reliableinformation and fluctuations in currency exchange rateswhere investments are denominated in currencies otherthan the U.S. dollar. Certain events in foreign marketsmay adversely affect foreign and domestic issuers,including interruptions in the global supply chain,natural disasters and outbreak of infectious diseases. ThePortfolio’s investment in any country could be subjectto governmental actions such as capital or currencycontrols, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome. Foreign securities may also be more difficult toresell than comparable U.S. securities because themarkets for foreign securities are often less liquid. Evenwhen a foreign security increases in price in its localcurrency, the appreciation may be diluted by adversechanges in exchange rates when the security’s value isconverted to U.S. dollars. Foreign withholding taxes alsomay apply and errors and delays may occur in thesettlement process for foreign securities.

Emerging Markets Risk. The economic and politicalstructures of developing countries in emerging markets,in most cases, do not compare favorably with the U.S.or other developed countries in terms of wealth andstability, and their financial markets often lack liquidity.Portfolio performance will likely be negatively affectedby portfolio exposure to countries and corporationsdomiciled in or with revenue exposures to countries inthe midst of, among other things, hyperinflation,currency devaluation, trade disagreements, suddenpolitical upheaval, or interventionist governmentpolicies. Portfolio performance may also be negativelyaffected by portfolio exposure to countries andcorporations domiciled in or with revenue exposures tocountries with less developed legal, tax, regulatory, andaccounting systems. Significant buying or selling actionsby a few major investors may also heighten thevolatility of emerging markets. These factors makeinvesting in emerging market countries significantlyriskier than in other countries, and events in any onecountry could cause the Portfolio’s share price todecline.

Sovereign Debt Risk. Sovereign debt securities areissued or guaranteed by foreign governmental entities.These investments are subject to the risk that agovernmental entity may delay or refuse to pay interestor repay principal on its sovereign debt, due, forexample, to cash flow problems, insufficient foreigncurrency reserves, political considerations, the relativesize of the governmental entity’s debt position inrelation to the economy or the failure to put in placeeconomic reforms required by the International

Monetary Fund or other multilateral agencies. If agovernmental entity defaults, it may ask for more timein which to pay or for further loans. There is no legalprocess for collecting sovereign debts that a governmentdoes not pay nor are there bankruptcy proceedingsthrough which all or part of the sovereign debt that agovernmental entity has not repaid may be collected.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Other Funds Risk. Because the Portfolio invests inother funds managed by the Adviser or an affiliate(“Other Funds”), the performance of the Portfolio isdependent, in part, upon the performance of OtherFunds in which the Portfolio may invest. As a result, thePortfolio is subject to the same risks as those faced bythe Other Funds. In addition, Other Funds may besubject to additional fees and expenses that will beborne by the Portfolio.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets. There is also no guarantee thatthe Adviser will be able to effectively implement thePortfolio’s investment objective.

Conflicts of Interest Risk. An investment in thePortfolio will be subject to a number of actual orpotential conflicts of interest.For example, the Adviseror its affiliates may provide services to the Portfolio forwhich the Portfolio would compensate the Adviserand/or such affiliates. The Portfolio may invest in otherpooled investment vehicles sponsored, managed, orotherwise affiliated with the Adviser, including otherPortfolios. The Adviser may have an incentive (financialor otherwise) to enter into transactions or arrangementson behalf of the Portfolio with itself or its affiliates incircumstances where it might not have done sootherwise.

The Adviser or its affiliates manage other investmentfunds and/or accounts (including proprietary accounts)and have other clients with investment objectives andstrategies that are similar to, or overlap with, theinvestment objective and strategy of the Portfolio,creating conflicts of interest in investment andallocation decisions regarding the allocation of

Page 184: THRIVENT FLEXIBLE PREMIUM DEFERRED VARIABLE ANNUITY · 2020-04-30 · THRIVENT VARIABLE ANNUITY ACCOUNT C THRIVENT SERIES FUND,INC. PROSPECTUS FOR FLEXIBLE PREMIUM DEFERRED VARIABLE

investments that could be appropriate for the Portfolioand other clients of the Adviser or their affiliates.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Dealer inventories ofbonds are at or near historic lows in relation to marketsize, which has the potential to decrease liquidity andincrease price volatility in the fixed income markets,particularly during periods of economic or market stress.As a result of this decreased liquidity, the Portfolio mayhave to accept a lower price to sell a security, sell othersecurities to raise cash, or give up an investmentopportunity, any of which could have a negative effecton performance.

Derivatives Risk. The use of derivatives (such asfutures) involves additional risks and transaction costswhich could leave the Portfolio in a worse position thanif it had not used these instruments. The Portfolioutilizes futures on U.S. Treasuries in order to manageduration. The use of derivatives can lead to lossesbecause of adverse movements in the price or value ofthe underlying asset, index or rate, which may bemagnified by certain features of the contract. Changesin the value of the derivative may not correlate asintended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is the riskthat the other party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

ETF Risk. An ETF is subject to the risks of theunderlying investments that it holds. In addition, forindex-based ETFs, the performance of an ETF maydiverge from the performance of such index (commonlyknown as tracking error). ETFs are subject to fees andexpenses (like management fees and operatingexpenses) that do not apply to an index, and thePortfolio will indirectly bear its proportionate share ofany such fees and expenses paid by the ETFs in which itinvests. Because ETFs trade on an exchange, there is arisk that an ETF will trade at a discount to net assetvalue or that investors will fail to bring the trading pricein line with the underlying shares (known as thearbitrage mechanism).

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses which

are borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared tobroad-based securities market indices. The indexdescriptions appear in the �Index Descriptions� sectionof the prospectus. Call 800-847-4836 or visitThrivent.com for performance results current to themost recent month-end.

The bar chart includes the effects of Portfolio expenses,but not charges or deductions against your variablecontract, and assume that you sold your investment atthe end of the period. Because shares of the Portfolio areoffered through variable life insurance and variableannuity contracts, you should carefully review thevariable contract prospectus for information onapplicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

Effective August 16, 2013, based on approval of thePortfolio’s Board of Directors, the Portfolio’s investmentobjective and principal strategies were changed, whichhad the effect of converting the Portfolio from onewhich invested at least 80% of its assets inmortgage-related securities to one which invests in abroad range of fixed-income securities. At the sametime, the Portfolio’s name changed from ThriventMortgage Securities Portfolio to Thrivent OpportunityIncome Plus Portfolio. As a result, performanceinformation presented below with respect to periodsprior to August 16, 2013, reflects the performance of aninvestment portfolio that was materially different fromthe investment portfolio of Thrivent OpportunityIncome Plus Portfolio.

1 The Adviser has contractually agreed, through at least April 30,2021, to waive a portion of the management fees associated withthe shares of the Thrivent Partner Emerging Markets EquityPortfolio in order to limit the Total Annual Portfolio OperatingExpenses After Fee Waivers and/or Expense Reimbursements to anannual rate of 1.20% of the average daily net assets of the shares.This contractual provision, however, may be terminated before theindicated termination date upon the mutual agreement betweenthe Independent Directors of the Portfolio and the Adviser.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods. Inaddition, the example for the 1 Year period reflects theeffect of the contractual fee waiver and/or expensereimbursement. The example also assumes that your

investment has a 5% return each year, and that thePortfolio’s operating expenses remain the same.Although your actual cost may be higher or lower, basedon the foregoing assumptions, your cost would be:

Thrivent PartnerEmerging MarketsEquity Portfolio $122 $402 $703 $1,559

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 21% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes), at the time ofinitial purchase, in emerging market equities, includingcommon stock, preferred stock, convertible securities,depositary receipts and rights and warrants to buycommon stocks. A security is considered to be an“emerging market” security if issued by a company thatPortfolio management has determined meets one ormore of the following criteria:

• is organized under the laws of, or has its principaloffice in, an emerging market country;

• has its principal securities trading market in anemerging market country; and/or

• derives a majority of its annual revenue or earningsor assets from goods produced, sales made or servicesperformed in an emerging market country.

An “emerging market” country is any countrydetermined by the Adviser or subadviser to have anemerging market economy, considering factors such asthe country’s credit rating, its political and economicstability and the development of its financial andcapital markets. These emerging market countriesinclude every nation in the world except the U.S.,Canada, Israel, Japan, Australia, New Zealand, HongKong, Singapore and all nations typically consideredpart of Western Europe. At times, the Portfolio mayhave a significant amount of its assets invested in acountry or geographic region.

The Portfolio may also invest in equity securities ofissuers that are not tied economically to emergingmarket countries. The Portfolio may invest in securitiesdenominated in U.S. dollars and currencies of emergingmarket countries in which it may invest. The Portfoliotypically has full currency exposure to those markets inwhich it invests.

The Portfolio may invest in securities of any marketcapitalization, including small and mid-cap securities.

The Portfolio may invest in securities of any marketsector and may hold a significant amount of securitiesof companies, from time to time, within a single sectorsuch as financials.

The Portfolio’s subadviser, Aberdeen Asset ManagersLimited (“Aberdeen”), uses a disciplined investmentprocess based on its proprietary research to determinesecurity selection. Aberdeen seeks to identify “quality”companies, based on factors such as strength ofmanagement and business, that trade at reasonablevaluations, based on factors such as earnings growthand other key financial measurements. Aberdeen alsoevaluates matters of long term value by examining aspectrum of considerations such as governance and riskmanagement, including those risks often referred to asenvironmental, social and governance factors (�ESG�).ESG analysis is fully integrated into investmentdecisions for all equity holdings. As such, Aberdeenevaluates ESG factors as part of the investment analysisprocess and this forms an integral component ofAberdeen’s quality rating for all companies. Aberdeenmakes investments for the long-term, although it maysell a security when it perceives a company’s businessdirection or growth prospects to have changed or thecompany’s valuations are no longer attractive.

Should the Adviser determine that the Portfolio wouldbenefit from reducing the percentage of its net assetsinvested in emerging market equities from 80% to alesser amount, it will notify you at least 60 days prior tothe change.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Emerging Markets Risk. The economic and politicalstructures of developing countries in emerging markets,in most cases, do not compare favorably with the U.S.or other developed countries in terms of wealth andstability, and their financial markets often lack liquidity.Portfolio performance will likely be negatively affectedby portfolio exposure to countries and corporationsdomiciled in or with revenue exposures to countries inthe midst of, among other things, hyperinflation,

currency devaluation, trade disagreements, suddenpolitical upheaval, or interventionist governmentpolicies. Portfolio performance may also be negativelyaffected by portfolio exposure to countries andcorporations domiciled in or with revenue exposures tocountries with less developed legal, tax, regulatory, andaccounting systems. Significant buying or selling actionsby a few major investors may also heighten thevolatility of emerging markets. These factors makeinvesting in emerging market countries significantlyriskier than in other countries, and events in any onecountry could cause the Portfolio’s share price todecline.

Foreign Securities Risk. Foreign securities generallycarry more risk and are more volatile than theirdomestic counterparts, in part because of potential forhigher political and economic risks, lack of reliableinformation and fluctuations in currency exchange rateswhere investments are denominated in currencies otherthan the U.S. dollar. Certain events in foreign marketsmay adversely affect foreign and domestic issuers,including interruptions in the global supply chain,natural disasters and outbreak of infectious diseases. ThePortfolio’s investment in any country could be subjectto governmental actions such as capital or currencycontrols, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome. Foreign securities may also be more difficult toresell than comparable U.S. securities because themarkets for foreign securities are often less liquid. Evenwhen a foreign security increases in price in its localcurrency, the appreciation may be diluted by adversechanges in exchange rates when the security’s value isconverted to U.S. dollars. Foreign withholding taxes alsomay apply and errors and delays may occur in thesettlement process for foreign securities.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decrease

TSF-134

Page 189: THRIVENT FLEXIBLE PREMIUM DEFERRED VARIABLE ANNUITY · 2020-04-30 · THRIVENT VARIABLE ANNUITY ACCOUNT C THRIVENT SERIES FUND,INC. PROSPECTUS FOR FLEXIBLE PREMIUM DEFERRED VARIABLE

more than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Financial Sector Risk. To the extent that thefinancials sector continues to represent a significantportion of the Portfolio, the Portfolio will be sensitive tochanges in, and its performance may depend to agreater extent on, factors impacting this sector.Performance of companies in the financials sector maybe adversely impacted by many factors, including,among others, government regulations, economicconditions, credit rating downgrades, changes ininterest rates, and decreased liquidity in credit markets.The impact of more stringent capital requirements,recent or future regulation of any individual financialcompany or recent or future regulation of the financialssector as a whole cannot be predicted. In recent years,cyber attacks and technology malfunctions and failureshave become increasingly frequent in this sector andhave caused significant losses.

Foreign Currency Risk. The value of a foreigncurrency may decline against the U.S. dollar, whichwould reduce the dollar value of securities denominatedin that currency. The overall impact of such a decline offoreign currency can be significant, unpredictable, andlong lasting, depending on the currencies represented,how each one appreciates or depreciates in relation tothe U.S. dollar, and whether currency positions arehedged. Under normal conditions, the Portfolio doesnot engage in extensive foreign currency hedgingprograms. Further, exchange rate movements arevolatile, and it is not possible to effectively hedge thecurrency risks of many developing countries.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser orsubadviser in assessing the potential of the investmentsin which the Portfolio invests. This assessment ofinvestments may prove incorrect, resulting in losses orpoor performance, even in rising markets. There is alsono guarantee that the Adviser will be able to effectivelyimplement the Portfolio’s investment objective.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Mid Cap Risk. Medium-sized companies often havegreater price volatility, lower trading volume, and lessliquidity than larger, more-established companies. Thesecompanies tend to have smaller revenues, narrowerproduct lines, less management depth and experience,smaller shares of their product or service markets, fewerfinancial resources, and less competitive strength thanlarger companies.

Small Cap Risk. Smaller, less seasoned companiesoften have greater price volatility, lower trading volume,and less liquidity than larger, more establishedcompanies. These companies tend to have smallrevenues, narrower product lines, less managementdepth and experience, small shares of their product orservice markets, fewer financial resources, and lesscompetitive strength than larger companies. Suchcompanies seldom pay significant dividends that couldsoften the impact of a falling market on returns.

Preferred Securities Risk. There are certainadditional risks associated with investing in preferredsecurities, including, but not limited to, preferredsecurities may include provisions that permit the issuer,at its discretion, to defer or omit distributions for astated period without any adverse consequences to theissuer; preferred securities are generally subordinated tobonds and other debt instruments in a company’scapital structure in terms of having priority to corporateincome and liquidation payments, and therefore will besubject to greater credit risk than more senior debtinstruments; preferred securities may be substantiallyless liquid than many other securities, such as commonstocks or U.S. Government securities; generally,traditional preferred securities offer no voting rightswith respect to the issuing company unless preferreddividends have been in arrears for a specified number ofperiods, at which time the preferred security holdersmay elect a number of directors to the issuer’s board;and in certain varying circumstances, an issuer ofpreferred securities may redeem the securities prior to aspecified date.

Convertible Securities Risk. Convertible securities aresubject to the usual risks associated with debt securities,such as interest rate risk and credit risk. Convertiblesecurities also react to changes in the value of thecommon stock into which they convert, and are thussubject to market risk. The Portfolio may also be forcedto convert a convertible security at an inopportunetime, which may decrease the Portfolio’s return.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19

Thrivent Partner Growth Stock PortfolioInvestment ObjectivesThe investment objective of the Thrivent PartnerGrowth Stock Portfolio (the �Portfolio�) is to achievelong-term growth of capital and, secondarily, increasedividend income.

If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods.The example also assumes that your investment has a5% return each year, and that the Portfolio’s operatingexpenses remain the same. Although your actual costmay be higher or lower, based on the foregoingassumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent PartnerGrowth StockPortfolio $75 $233 $406 $906

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 29% ofthe average value of its portfolio.

Principal StrategiesThe Portfolio’s principal strategy for achieving itsinvestment objectives under normal circumstances is toinvest at least 80% of net assets (plus the amount of anyborrowing for investment purposes) in common stocks.Should the Adviser determine that the Portfolio wouldbenefit from reducing the percentage of its assetsinvested in common stocks from 80% to a lesseramount, it will notify you at least 60 days prior to sucha change.

The Portfolio concentrates its investments in growthcompanies. The Portfolio’s subadviser, T. Rowe PriceAssociates, Inc. (“T. Rowe Price”), seeks investments incompanies that have the ability to pay increasingdividends through strong cash flow. The subadvisergenerally looks for companies with an above-averagerate of earnings growth and a lucrative niche in theeconomy that gives them the ability to sustain earningsmomentum even during times of slow economicgrowth. T. Rowe Price believes that when a companyincreases its earnings faster than both inflation and theoverall economy, the market will eventually reward itwith a higher stock price. The Portfolio may at timesinvest significantly in certain sectors, such as theinformation technology sector.

In pursuing the Portfolio’s investment objectives, T.Rowe Price has the discretion to purchase somesecurities that do not meet its normal investmentcriteria, as described above, when it believes suchpurchase will provide an opportunity for substantialappreciation. These situations might arise when T. RowePrice believes a security could increase in value for avariety of reasons including a change in management,an extraordinary corporate event, a new productintroduction or innovation, or a favorable competitivedevelopment.

While the Portfolio invests primarily (at least 80%) incommon stocks, it may also invest in foreign stocks (upto 30% of total assets), and futures and options toobtain investment exposure or for hedging, in keepingwith the Portfolio’s objectives.

The Portfolio may sell securities for a variety of reasons,such as to secure gains, limit losses, or reposition assetsinto more promising opportunities.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objectives and you could lose money byinvesting in the Portfolio.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Technology-Oriented Companies Risk. Commonstocks of companies that rely extensively on technology,science or communications in their productdevelopment or operations may be more volatile thanthe overall stock market and may or may not move intandem with the overall stock market. Technology,science and communications are rapidly changingfields, and stocks of these companies, especially ofsmaller or unseasoned companies, may be subject tomore abrupt or erratic market movements than thestock market in general. There are significantcompetitive pressures among technology-orientedcompanies and the products or operations of suchcompanies may become obsolete quickly. In addition,these companies may have limited product lines,markets or financial resources and the management of

such companies may be more dependent upon one or afew key people.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser orsubadviser in assessing the potential of the investmentsin which the Portfolio invests. This assessment ofinvestments may prove incorrect, resulting in losses orpoor performance, even in rising markets. There is alsono guarantee that the Adviser will be able to effectivelyimplement the Portfolio’s investment objective.

Foreign Securities Risk. Foreign securities generallycarry more risk and are more volatile than theirdomestic counterparts, in part because of potential forhigher political and economic risks, lack of reliableinformation and fluctuations in currency exchange rateswhere investments are denominated in currencies otherthan the U.S. dollar. Certain events in foreign marketsmay adversely affect foreign and domestic issuers,including interruptions in the global supply chain,natural disasters and outbreak of infectious diseases. ThePortfolio’s investment in any country could be subjectto governmental actions such as capital or currencycontrols, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome. Foreign securities may also be more difficult toresell than comparable U.S. securities because themarkets for foreign securities are often less liquid. Evenwhen a foreign security increases in price in its localcurrency, the appreciation may be diluted by adversechanges in exchange rates when the security’s value isconverted to U.S. dollars. Foreign withholding taxes alsomay apply and errors and delays may occur in thesettlement process for foreign securities.

Derivatives Risk. The use of derivatives (such asfutures and options) involves additional risks andtransaction costs which could leave the Portfolio in aworse position than if it had not used theseinstruments. The Portfolio utilizes equity futures inorder to increase or decrease its exposure to various assetclasses at a lower cost than trading stocks directly. Theuse of derivatives can lead to losses because of adversemovements in the price or value of the underlying asset,index or rate, which may be magnified by certainfeatures of the contract. Changes in the value of thederivative may not correlate as intended with theunderlying asset, rate or index, and the Portfolio couldlose much more than the original amount invested.Derivatives can be highly volatile, illiquid and difficultto value. Certain derivatives may also be subject to

counterparty risk, which is the risk that the other partyin the transaction will not fulfill its contractualobligations due to its financial condition, marketevents, or other reasons.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance.

Thrivent Partner Healthcare PortfolioInvestment ObjectiveThrivent Partner Healthcare Portfolio (the �Portfolio�)seeks long-term capital growth.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a % of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the lower of the original purchaseprice or current net asset value) N/A

ANNUAL PORTFOLIO OPERATING EXPENSES(expenses that you pay each year as a percentage ofthe value of your investment)

Management Fees 0.83%

Other Expenses 0.10%

Total Annual Portfolio Operating Expenses 0.93%

Less Fee Waivers and/or ExpenseReimbursements1 0.05%

Total Annual Portfolio Operating Expenses AfterFee Waivers and/or Expense Reimbursements 0.88%

1 The Adviser has contractually agreed, through at least April 30,2021, to waive a portion of the management fees associated withthe shares of the Thrivent Partner Healthcare Portfolio equal in theaggregate to 0.05% of the average daily net assets of the shares. Thiscontractual provision, however, may be terminated before theindicated termination date upon the mutual agreement betweenthe Independent Directors of the Portfolio and the Adviser.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods. Inaddition, the example for the 1 Year period reflects theeffect of the contractual fee waiver and/or expensereimbursement. The example also assumes that yourinvestment has a 5% return each year, and that the

Portfolio’s operating expenses remain the same.Although your actual cost may be higher or lower, basedon the foregoing assumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent PartnerHealthcare Portfolio $90 $291 $510 $1,138

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 44% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio will invest atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in the securities ofcompanies that are engaged in the development,production or distribution of pharmaceutical, generic,biotechnology and medical technology products orservices (“healthcare companies”). Healthcarecompanies are those that derive at least 50% of theirannual revenues from the production of such productsand provision of such services or have at least 50% oftheir assets in such products or services. The Portfolioinvests primarily in equity securities of both U.S. andnon-U.S. companies (including American DepositaryReceipts and issuers in emerging markets) and, as anon-diversified fund under the Investment CompanyAct of 1940 (the “1940 Act”), focuses its investments inthe securities of a relatively few number of issuers. Inaddition, the Portfolio concentrates its investments inthe securities of companies in the healthcare industry,some of which may be small- and medium-sizedcompanies. Should the Adviser determine that thePortfolio would benefit from reducing the percentage ofits assets invested in the securities of healthcarecompanies from 80% to a lesser amount, it will notifyyou at least 60 days prior to the change.

BlackRock Investment Management, LLC, the Portfolio’ssubadviser, considers a variety of factors when choosinginvestments for the Portfolio, including (i) identifyingcompanies and industries that appear to have thepotential for above-average returns; and (ii) identifyingcompanies that are expected to show above-averagegrowth over the long-term, as well as those that appear

Page 198: THRIVENT FLEXIBLE PREMIUM DEFERRED VARIABLE ANNUITY · 2020-04-30 · THRIVENT VARIABLE ANNUITY ACCOUNT C THRIVENT SERIES FUND,INC. PROSPECTUS FOR FLEXIBLE PREMIUM DEFERRED VARIABLE

to be trading below their true worth. The Portfolio willgenerally sell a stock when, in the opinion of thesubadviser, the stock reaches its price target or if there isdeterioration in the company’s fundamentals, a changein macroeconomic outlook, technical deterioration,valuation issues, a need to rebalance the Portfolio or abetter opportunity elsewhere.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Healthcare Industry Risk. As a sector fund thatinvests primarily in the healthcare industry, thePortfolio is subject to the risk that the companies in thatindustry are likely to react similarly to legislative orregulatory changes, adverse market conditions and/orincreased competition affecting their market segment.Due to the rapid pace of technological development,there is the risk that the products and servicesdeveloped by these companies may become rapidlyobsolete or have relatively short product cycles. There isalso the risk that the products and services offered bythese companies will not meet expectations or evenreach the marketplace.

Non-Diversified Risk. The Portfolio is not“diversified” within the meaning of the 1940 Act. Thatmeans the Portfolio may invest a greater percentage ofits assets in the securities of any single issuer comparedto other funds. A non-diversified portfolio is generallymore susceptible than a diversified portfolio to the riskthat events or developments affecting a particular issueror industry will significantly affect the Portfolio’sperformance.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable to

adverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Mid Cap Risk. Medium-sized companies often havegreater price volatility, lower trading volume, and lessliquidity than larger, more-established companies. Thesecompanies tend to have smaller revenues, narrowerproduct lines, less management depth and experience,smaller shares of their product or service markets, fewerfinancial resources, and less competitive strength thanlarger companies.

Small Cap Risk. Smaller, less seasoned companiesoften have greater price volatility, lower trading volume,and less liquidity than larger, more establishedcompanies. These companies tend to have smallrevenues, narrower product lines, less managementdepth and experience, small shares of their product orservice markets, fewer financial resources, and lesscompetitive strength than larger companies. Suchcompanies seldom pay significant dividends that couldsoften the impact of a falling market on returns.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser orsubadviser in assessing the potential of the investmentsin which the Portfolio invests. This assessment ofinvestments may prove incorrect, resulting in losses orpoor performance, even in rising markets. There is alsono guarantee that the Adviser will be able to effectivelyimplement the Portfolio’s investment objective.

Foreign Securities Risk. Foreign securities generallycarry more risk and are more volatile than theirdomestic counterparts, in part because of potential forhigher political and economic risks, lack of reliableinformation and fluctuations in currency exchange rateswhere investments are denominated in currencies otherthan the U.S. dollar. Certain events in foreign marketsmay adversely affect foreign and domestic issuers,including interruptions in the global supply chain,natural disasters and outbreak of infectious diseases. ThePortfolio’s investment in any country could be subjectto governmental actions such as capital or currencycontrols, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome. Foreign securities may also be more difficult toresell than comparable U.S. securities because themarkets for foreign securities are often less liquid. Evenwhen a foreign security increases in price in its localcurrency, the appreciation may be diluted by adverse

Page 199: THRIVENT FLEXIBLE PREMIUM DEFERRED VARIABLE ANNUITY · 2020-04-30 · THRIVENT VARIABLE ANNUITY ACCOUNT C THRIVENT SERIES FUND,INC. PROSPECTUS FOR FLEXIBLE PREMIUM DEFERRED VARIABLE

changes in exchange rates when the security’s value isconverted to U.S. dollars. Foreign withholding taxes alsomay apply and errors and delays may occur in thesettlement process for foreign securities.

Emerging Markets Risk. The economic and politicalstructures of developing countries in emerging markets,in most cases, do not compare favorably with the U.S.or other developed countries in terms of wealth andstability, and their financial markets often lack liquidity.Portfolio performance will likely be negatively affectedby portfolio exposure to countries and corporationsdomiciled in or with revenue exposures to countries inthe midst of, among other things, hyperinflation,currency devaluation, trade disagreements, suddenpolitical upheaval, or interventionist governmentpolicies. Portfolio performance may also be negativelyaffected by portfolio exposure to countries andcorporations domiciled in or with revenue exposures tocountries with less developed legal, tax, regulatory, andaccounting systems. Significant buying or selling actionsby a few major investors may also heighten thevolatility of emerging markets. These factors makeinvesting in emerging market countries significantlyriskier than in other countries, and events in any onecountry could cause the Portfolio’s share price todecline.

Foreign Currency Risk. The value of a foreigncurrency may decline against the U.S. dollar, whichwould reduce the dollar value of securities denominatedin that currency. The overall impact of such a decline offoreign currency can be significant, unpredictable, andlong lasting, depending on the currencies represented,how each one appreciates or depreciates in relation tothe U.S. dollar, and whether currency positions arehedged. Under normal conditions, the Portfolio doesnot engage in extensive foreign currency hedgingprograms. Further, exchange rate movements arevolatile, and it is not possible to effectively hedge thecurrency risks of many developing countries.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to year

and by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared toa broad-based securities market index. The indexdescription appears in the �Index Descriptions� sectionof the prospectus. Call 800-847-4836 or visitThrivent.com for performance results current to themost recent month-end.

The bar chart includes the effects of Portfolio expenses,but not charges or deductions against your variablecontract, and assumes that you sold your investment atthe end of the period. Because shares of the Portfolio areoffered through variable life insurance and variableannuity contracts, you should carefully review thevariable contract prospectus for information onapplicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

1 Year 3 Years 5 Years 10 Years

Thrivent Real EstateSecurities Portfolio $87 $271 $471 $1,049

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 23% ofthe average value of its portfolio.

Principal StrategiesIn seeking to achieve its investment objective, thePortfolio focuses on income-producing common stocksand other equity securities of U.S. real estate companies.Under normal circumstances, the Portfolio invests atleast 80% of its net assets (plus any borrowings forinvestment purposes) in companies that are primarilyengaged in the real estate industry. This includescompanies such as real estate investment trusts (REITs)and other real estate related investments. A real estatecompany generally derives at least 50% of its revenuefrom real estate ownership, leasing, management,development, financing or sale of residential,commercial or industrial real estate—or has at least 50%of its assets in real estate. Should the Adviser determinethat the Portfolio would benefit from reducing thepercentage of assets invested in companies that areprimarily engaged in the real estate industry from 80%to a lesser amount, it will notify you at least 60 daysprior to such a change.

This Portfolio may invest up to 20% of its assets inequity and fixed income securities of companies whichare not principally engaged in the real estate industry orwhich are not income producing equity securities ofcompanies principally engaged in the U.S. real estateindustry.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Real Estate Investment Trust (“REIT”) Risk. REITsgenerally can be divided into three types: equity REITs,mortgage REITs, and hybrid REITs (which combine thecharacteristics of equity REITs and mortgage REITs).Equity REITs will be affected by changes in the values of,and income from, the properties they own, whilemortgage REITs may be affected by the credit quality ofthe mortgage loans they hold. All REIT types may be

Page 203: THRIVENT FLEXIBLE PREMIUM DEFERRED VARIABLE ANNUITY · 2020-04-30 · THRIVENT VARIABLE ANNUITY ACCOUNT C THRIVENT SERIES FUND,INC. PROSPECTUS FOR FLEXIBLE PREMIUM DEFERRED VARIABLE

affected by changes in interest rates. The effect of risinginterest rates is generally more pronounced for highdividend paying stock than for stocks that pay little orno dividends. This may cause the value of real estatesecurities to decline during periods of rising interestrates, which would reduce the overall return of thePortfolio. REITs are subject to additional risks, includingthe fact that they are dependent on specializedmanagement skills that may affect the REITs’ abilities togenerate cash flows for operating purposes and formaking investor distributions. REITs may have limiteddiversification and are subject to the risks associatedwith obtaining financing for real property. As with anyinvestment, there is a risk that REIT securities and otherreal estate industry investments may be overvalued atthe time of purchase. In addition, a REIT can pass itsincome through to its investors without any tax at theentity level if it complies with various requirementsunder the Internal Revenue Code. There is the risk,however, that a REIT held by the Portfolio will fail toqualify for this tax-free pass-through treatment of itsincome. By investing in REITs indirectly through thePortfolio, in addition to bearing a proportionate share ofthe expenses of the Portfolio, you will also indirectlybear similar expenses of the REITs in which the Portfolioinvests.

Real Estate Industry Risk. To the extent thePortfolio allocates assets to companies in the real estatebusiness, the Portfolio is subject to real estate industryrisk. Declines in real estate values, changes in interestrates or economic downturns can have a significantnegative effect on companies in the real estate industry.Other adverse changes could include, but are notlimited to, extended vacancies of properties, increasedcompetition, overbuilding and changes in zoning lawand government regulations.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable to

adverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets. There is also no guarantee thatthe Adviser will be able to effectively implement thePortfolio’s investment objective.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance.

Thrivent Small Cap Growth PortfolioInvestment ObjectiveThrivent Small Cap Growth Portfolio (the �Portfolio�)seeks long-term capital growth. The Portfolio’sinvestment objective may be changed withoutshareholder approval.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a % of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the lower of the original purchaseprice or current net asset value) N/A

ANNUAL PORTFOLIO OPERATING EXPENSES(expenses that you pay each year as a percentage ofthe value of your investment)

Management Fees 0.80%

Other Expenses 0.92%

Acquired Fund Fees and Expenses 0.01%

Total Annual Portfolio Operating Expenses 1.73%

Less Fee Waivers and/or ExpenseReimbursements1 0.78%

Total Annual Portfolio Operating Expenses AfterFee Waivers and/or Expense Reimbursements 0.95%

1 The Adviser has contractually agreed, through at least April 30,2021, to waive a portion of the management fees associated withthe shares of the Thrivent Small Cap Growth Portfolio in order tolimit the Total Annual Portfolio Operating Expenses After FeeWaivers and/or Expense Reimbursements to an annual rate of0.94% of the average daily net assets of the shares. This contractualprovision, however, may be terminated before the indicatedtermination date upon the mutual agreement between theIndependent Directors of the Portfolio and the Adviser.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods. In

addition, the example for the 1 Year period reflects theeffect of the contractual fee waiver and/or expensereimbursement. The example also assumes that yourinvestment has a 5% return each year, and that thePortfolio’s operating expenses remain the same.Although your actual cost may be higher or lower, basedon the foregoing assumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent Small CapGrowth Portfolio $97 $469 $865 $1,976

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 51% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in equity securitiesof small companies. The Adviser focuses mainly in theequity securities of smaller U.S. companies which havemarket capitalizations equivalent to those companiesincluded in widely known indices such as the Russell2000 Growth Index, S&P SmallCap 600 Index, or thesmall company market capitalization classificationpublished by Lipper, Inc. These companies typicallyhave a market capitalization of less than $6 billion.Should the Adviser change the investments used forpurposes of this 80% threshold, you will be notified atleast 60 days prior to the change.

The Portfolio seeks to achieve its investment objectiveby investing primarily in common stocks. The Adviseruses fundamental, quantitative, and technicalinvestment research techniques and focuses on stocks ofcompanies that it believes have demonstrated andbelieves will sustain above-average revenue and earningsgrowth over time, or which are expected to developrapid sales and earnings growth in the future whencompared to the economy and stock market as a whole.Many such companies are in the technology sector andthe Portfolio may at times have a higher concentrationin this industry.

The Adviser may sell securities for a variety of reasons,such as to secure gains, limit losses, or reposition assetsto more promising opportunities.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Small Cap Risk. Smaller, less seasoned companiesoften have greater price volatility, lower trading volume,and less liquidity than larger, more establishedcompanies. These companies tend to have smallrevenues, narrower product lines, less managementdepth and experience, small shares of their product orservice markets, fewer financial resources, and lesscompetitive strength than larger companies. Suchcompanies seldom pay significant dividends that couldsoften the impact of a falling market on returns.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Technology-Oriented Companies Risk. Commonstocks of companies that rely extensively on technology,science or communications in their productdevelopment or operations may be more volatile thanthe overall stock market and may or may not move in

tandem with the overall stock market. Technology,science and communications are rapidly changingfields, and stocks of these companies, especially ofsmaller or unseasoned companies, may be subject tomore abrupt or erratic market movements than thestock market in general. There are significantcompetitive pressures among technology-orientedcompanies and the products or operations of suchcompanies may become obsolete quickly. In addition,these companies may have limited product lines,markets or financial resources and the management ofsuch companies may be more dependent upon one or afew key people.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets. There is also no guarantee thatthe Adviser will be able to effectively implement thePortfolio’s investment objective.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for the one-year period and since inceptioncompared to broad-based securities market indices. Theindex descriptions appear in the �Index Descriptions�section of the prospectus. The Portfolio now comparesits returns to the Russell 2000 Growth Index because itis commonly used by funds with the same investmentobjective and principal strategies as the Portfolio.

investment at the end of the period. Because shares ofthe Portfolio are offered through variable life insuranceand variable annuity contracts, you should carefullyreview the variable contract prospectus for informationon applicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

Thrivent Small Cap Index PortfolioInvestment ObjectiveThrivent Small Cap Index Portfolio (the �Portfolio�)seeks capital growth that tracks the performance of theS&P SmallCap 600 Index.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges.

If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods.The example also assumes that your investment has a5% return each year, and that the Portfolio’s operatingexpenses remain the same. Although your actual costmay be higher or lower, based on the foregoingassumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent Small CapIndex Portfolio $26 $80 $141 $318

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 30% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio investssubstantially all of its assets (more than 80% of its netassets, plus the amount of any borrowings forinvestment purposes) in small company common stocksincluded in the S&P SmallCap 600 Index in theproportions in which they are represented in the Index.This is a passively managed Portfolio, which means thatthe Adviser does not choose the securities that make upthe Portfolio. The S&P SmallCap 600 Index is acapitalization-weighted index comprised of 600domestic small capitalization stocks chosen for marketsize, liquidity, and industry representation. Accordingly,the Portfolio invests in stocks of smaller companiesfrom a broad range of industries. The S&P SmallCap 600Index is adjusted quarterly, and when changes to theindex occur, the Adviser will attempt to replicate thesechanges within the Portfolio. However, any suchchanges may result in slight variations from time totime. The Portfolio may buy and sell equity indexfutures for investment exposure. For liquidity reasons,the Portfolio may invest to some degree in moneymarket instruments.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Small Cap Risk. Smaller, less seasoned companiesoften have greater price volatility, lower trading volume,and less liquidity than larger, more establishedcompanies. These companies tend to have smallrevenues, narrower product lines, less managementdepth and experience, small shares of their product orservice markets, fewer financial resources, and lesscompetitive strength than larger companies. Suchcompanies seldom pay significant dividends that couldsoften the impact of a falling market on returns.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Futures Contract Risk. The value of a futurescontract tends to increase and decrease in tandem withthe value of the underlying instrument. The price offutures can be highly volatile; using them could lowertotal return, and the potential loss from futures canexceed the Portfolio’s initial investment in suchcontracts. In addition, the value of the futures contractmay not accurately track the value of the underlyinginstrument.

Indexing Strategy/Index Tracking Risk. ThePortfolio is managed with an indexing investmentstrategy, attempting to track the performance of anunmanaged index of securities, regardless of the currentor projected performance of the Index or of the actualsecurities comprising the Index. The structure andcomposition of the Index will affect the performance,volatility, and risk of the Index and, consequently, theperformance, volatility, and risk of the Portfolio. Whilethe Adviser seeks to track the performance of the Index(i.e., achieve a high degree of correlation with theIndex), the Portfolio’s return may not match the returnof the Index. The Portfolio incurs a number of operatingexpenses not applicable to the Index, and incurs costs inbuying and selling securities. In addition, the Portfoliomay not be fully invested at times, generally as a resultof cash flows into or out of the Portfolio or reserves ofcash held by the Portfolio to meet redemptions. TheAdviser may attempt to replicate the Index return byinvesting in fewer than all of the securities in the Index,or in some securities not included in the Index,potentially increasing the risk of divergence between thePortfolio’s return and that of the Index.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared toa broad-based securities market index. The indexdescription appears in the �Index Descriptions� sectionof the prospectus. Call 800-847-4836 or visitThrivent.com for performance results current to themost recent month-end.

The bar chart and table include the effects of Portfolioexpenses, but not charges or deductions against yourvariable contract, and assume that you sold yourinvestment at the end of the period. Because shares ofthe Portfolio are offered through variable life insuranceand variable annuity contracts, you should carefullyreview the variable contract prospectus for informationon applicable charges and expenses.

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turns

over” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 53% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in equity securitiesof small companies. The Adviser focuses mainly in theequity securities of smaller U.S. companies which havemarket capitalizations equivalent to those companiesincluded in widely known indices such as the Russell2000 Index, S&P SmallCap 600 Index, or the smallcompany market capitalization classifications publishedby Lipper, Inc. These companies typically have a marketcapitalization of less than $6 billion. Should the Adviserchange the investments used for purposes of this 80%threshold, you will be notified at least 60 days prior tothe change.

The Portfolio seeks to achieve its investment objectiveby investing primarily in common stocks. The Adviseruses fundamental, quantitative, and technicalinvestment research techniques to determine whatsecurities to buy and sell. Fundamental techniquesassess a security’s value based on an issuer’s financialprofile, management, and business prospects whilequantitative and technical techniques involve a moredata-oriented analysis of financial information, markettrends and price movements. The Adviser looks forsmall companies that, in its opinion:

• have an improving fundamental outlook;• have capable management; and• are financially sound.

The Adviser may sell securities for a variety of reasons,such as to secure gains, limit losses, or reposition assetsto more promising opportunities.

Principal RisksThe Portfolio is subject to the following principalinvestment risks, which you should review carefully andin entirety. The Portfolio may not achieve itsinvestment objective and you could lose money byinvesting in the Portfolio.

Small Cap Risk. Smaller, less seasoned companiesoften have greater price volatility, lower trading volume,and less liquidity than larger, more establishedcompanies. These companies tend to have small

revenues, narrower product lines, less managementdepth and experience, small shares of their product orservice markets, fewer financial resources, and lesscompetitive strength than larger companies. Suchcompanies seldom pay significant dividends that couldsoften the impact of a falling market on returns.

Equity Security Risk. Equity securities held by thePortfolio may decline significantly in price, sometimesrapidly or unpredictably, over short or extended periodsof time, and such declines may occur because ofdeclines in the equity market as a whole, or because ofdeclines in only a particular country, company,industry, or sector of the market. From time to time, thePortfolio may invest a significant portion of its assets incompanies in one or more related sectors or industrieswhich would make the Portfolio more vulnerable toadverse developments affecting such sectors orindustries. Equity securities are generally more volatilethan most debt securities.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry or due to impacts from the spread ofinfectious illness, public health threats or similar issues.

Issuer Risk. Issuer risk is the possibility that factorsspecific to an issuer to which the Portfolio is exposedwill affect the market prices of the issuer’s securities andtherefore the value of the Portfolio.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets. There is also no guarantee thatthe Adviser will be able to effectively implement thePortfolio’s investment objective.

Health Crisis Risk. The global pandemic outbreak ofthe novel coronavirus known as COVID-19 has resultedin substantial market volatility and global businessdisruption. The duration and full effects of the outbreakare uncertain and may result in trading suspensions andmarket closures, limit liquidity and the ability of thePortfolio to process shareholder redemptions, andnegatively impact Portfolio performance. The COVID-19outbreak and future pandemics could affect the globaleconomy in ways that cannot be foreseen and mayexacerbate other types of risks, negatively impacting thevalue of the Portfolio.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared tobroad-based securities market indices. The indexdescriptions appear in the �Index Descriptions� sectionof the prospectus. The Portfolio now compares itsreturns to the Russell 2000 Index because it iscommonly used by funds with the same investmentobjective and principal strategies as the Portfolio. Call800-847-4836 or visit Thrivent.com for performanceresults current to the most recent month-end.

The bar chart and table include the effects of Portfolioexpenses, but not charges or deductions against yourvariable contract, and assume that you sold yourinvestment at the end of the period. Because shares ofthe Portfolio are offered through variable life insuranceand variable annuity contracts, you should carefullyreview the variable contract prospectus for informationon applicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

How a Portfolio has performed in the past is notnecessarily an indication of how it will perform in thefuture. Performance information provides someindication of the risks of investing in the Portfolio byshowing changes in the Portfolio’s performance overtime.
