INDEPENDENT AUDITORS’ REPORT

The Board of Directors and Shareholders Richtek Technology Corporation We have audited the accompanying balance sheets of Richtek Technology Corporation as of December 31, 2009 and 2008, and the related statements of income, changes in shareholders’ equity and cash flows for the years then ended. These financial statements are the responsibility of the Corporation’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with the Rules Governing the Audit of Financial Statements by Certified Public Accountants and auditing standards generally accepted in the Republic of China. Those rules and standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Richtek Technology Corporation as of December 31, 2009 and 2008, and the results of its operations and its cash flows for the years then ended, in conformity with the Guidelines Governing the Preparation of Financial Reports by Securities Issuers, requirements of the Business Accounting Law and Guidelines Governing Business Accounting relevant to financial accounting standards and accounting principles generally accepted in the Republic of China. As stated in Note 3 to the financial statements, effective January 1, 2009, the Company adopted the newly released statement of Financial Accounting Standards No. 10 “Accounting for Inventories.” In addition, effective January 1, 2008, the Company adopted the Interpretation 2007-052, “Accounting for Bonuses to Employees, Directors and Supervisors” issued by the Accounting Research and Development Foundation of the Republic of China which requires companies to record bonuses paid to employees, directors and supervisors as an expense rather than an appropriation of earnings.

RICHTEK TECHNOLOGY CORPORATION

NOTES TO FINANCIAL STATEMENTS

YEARS ENDED DECEMBER 31, 2009 AND 2008

(In Thousands of New Taiwan Dollars, Unless Stated Otherwise)

1. ORGANIZATION AND OPERATIONS

Richtek Technology Corporation (the “Corporation” or “Richtek”) was incorporated on September 18, 1998 and started operations on September 28, 1998. The Corporation’s shares have been listed on the Taiwan Stock Exchange since October 21, 2003. The Corporation designs, tests and sells integrated circuits (ICs) and information software. As of December 31, 2009 and 2008, the Corporation had 455 and 454 employees, respectively.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The financial statements have been prepared in conformity with the Guidelines Governing the Preparation of Financial Reports by Securities Issuers, Business Accounting Law, Guidelines Governing Business Accounting, and accounting principles generally accepted in the Republic of China (ROC). Under these guidelines, law and principles, certain estimates and assumptions have been used for the allowance for sales returns and discounts, allowance for doubtful accounts, allowance for loss on inventories, depreciation of properties, plant and equipment, pension cost, amortization of deferred charges and bonuses to employees, directors and supervisors, etc. Actual results may differ from these estimates. For readers’ convenience, the accompanying financial statements have been translated into English from the original Chinese version prepared and used in the ROC. If inconsistencies arise between the English version and the Chinese version or if differences arise in the interpretations between the two versions, the Chinese version of the financial statements shall prevail. Significant accounting policies are summarized as follows:

Current and Noncurrent Assets and Liabilities

Current assets include cash and those assets expected to be realized, sold or consumed within one year from the balance sheet date. All other assets such as property, plant and equipment and intangible assets are classified as noncurrent. Current liabilities are those to be settled within one year from the balance sheet date. All other liabilities are classified as noncurrent.

Financial Assets/Liabilities at Fair Value through Profit or Loss

Derivatives that do not meet the criteria for hedge accounting are initially recognized at fair value, with transaction costs expensed as incurred. The derivatives are remeasured at fair value subsequently with changes in fair value recognized in earnings. On derecognition of a financial asset or a financial liability, the difference between its carrying amount and the sum of the consideration received and receivable or consideration paid and payable is recognized in profit or loss. A regular way purchase or sale of financial assets is accounted for using settlement date accounting. Fair value is estimated using valuation techniques incorporating estimates and assumptions that are consistent with prevailing market conditions. When the fair value is positive, the derivative is recognized as a financial asset; when the fair value is negative, the derivative is recognized as a financial liability.

- 10 -

Available-for-sale Financial Assets

Available-for-sale financial assets are initially measured at fair value plus transaction costs that are directly attributable to the acquisition. At each balance sheet date subsequent to initial recognition, available-for-sale financial assets are remeasured at fair value, with changes in fair value recognized in equity until the financial assets are disposed of, at which time, the cumulative gain or loss previously recognized in equity is included in profit or loss for the year. All regular way purchases or sales of financial assets are recognized and derecognized on a trade date basis.

The fair values of open-end mutual funds are based on their net asset value as of the balance sheet date. If there is objective evidence which indicates that a financial asset is impaired, a loss is recognized. If, in a subsequent period, the amount of the impairment loss decreases, for equity securities, the previously recognized impairment loss is reversed to the extent of the decrease and recorded as an adjustment to shareholders’ equity. Revenue Recognition, Accounts Receivable and Allowance for Doubtful Accounts

The Corporation recognizes revenue when product shipment is made, price is fixed or determinable, and collectability is reasonably assured. When products are outsourced for additional processing, the rewards of ownership and significant risks associated with the products have not been transferred; therefore, revenue is not recognized for such products. Allowances for sales returns and discounts are generally made on the basis of historical experience, management’s judgment, and related factors. Sales are determined at fair value, taking into account related sales discounts agreed to by the Company and its customers. Since the receivables from sales are collectible within one year and sales transactions are frequent, the fair value of receivables is equivalent to the nominal amount of cash to be received. An allowance for doubtful accounts is provided on the basis of a review of the collectability and of as well as an examination of customers’ creditworthiness and the Corporation’s internal credit policies.

Inventories

Inventories consist of raw materials, finished goods and work-in-process. Before January 1, 2009, inventories were stated at the lower of cost or market value (replacement cost or net realizable value). Any write-down was made on a total-inventory basis. Market value meant replacement cost for raw materials and supplies and net realizable value for finished goods and work in process. As stated in note 3, effective January 1, 2009, inventories are stated at the lower of cost or net realizable value. Inventory write-downs are made item by item, except where it may be appropriate to group similar or related items. Net realizable value is the estimated selling price of inventories less all estimated costs of completion and costs necessary to make the sale. Inventories are recorded at weighted-average cost. Investments Accounted for Using Equity Method

Stock investments in which the Corporation holds more than 20% common shares with voting rights or exercises significant influence on investees’ operating and financial decisions are accounted for using the equity method. The acquisition cost is allocated to the assets acquired and liabilities assumed based on their fair values at the date of acquisition, and the excess of the acquisition cost over the fair value of the identifiable net assets acquired is recognized as goodwill. Goodwill is not being amortized. In addition, goodwill should be assessed for impairment annually or whenever an event or circumstances would result in the goodwill reduction.

When the Corporation subscribes for additional investee’s shares at a percentage different from its existing ownership percentage, the resulting carrying amount of the investment in the investee differs from the amount of the Corporation’s share of the investee’s equity. The Corporation records such a difference as an adjustment to long-term investments with the corresponding amount charged or credited to capital surplus. If the amount of such adjustment made to debit capital surplus is more than the balance of capital surplus arising from long-term equity investment, then the resulting difference is debited to retained earnings. If an investment is identified as significantly impaired, the carrying amount of the investment in excess of its recoverable amount is recognized as impairment loss. The assessment for impairment is based on carrying value. For those investees over which the Corporation holds a controlling interest, the assessment of impairment is based on an estimation of the value in use of the cash-generating units of the consolidated investees. Profits from downstream transaction with an equity-method investees that are not majority owned are eliminated in proportion to the Corporation’s percentage of ownership in the investees; if the Company has control over the investee, all the profits are eliminated. Profits from upstream transactions with an equity-method investee are eliminated in proportion to the Company’s percentage of ownership in the investee. All of the above deferred gains are realized upon the sale of the related products to third parties.

Financial Assets Carried at Cost

Investments in equity instruments without a quoted market price in an active market and without fair value can be reliably measured are carried at their original cost. Cash dividends are recognized as investment income upon resolution of shareholders of an investee but are accounted for as a reduction to the original cost of investment if such dividends are declared on the earnings of the investee attributable to the period prior to the purchase of the investment. Stock dividends are recorded as an increase in the number of shares held and do not affect investment income. The cost per share is recalculated based on the new total number of shares. If there is objective evidence which indicates that a financial asset is impaired, a loss is recognized. A subsequent reversal of such impairment loss is not allowed.

Property, Plant and Equipment

Property, plant and equipment are stated at cost less accumulated depreciation. Major additions and improvements to property, plant and equipment are capitalized, while costs of repairs and maintenance are expensed currently. If significant asset impairment is determined on the balance sheet date, the carrying amount of an asset in excess of its recoverable amount is recognized as a loss. If the recoverable amount increases, the impairment loss reversal is recognized as a gain. However, the increased carrying amount of an asset due to impairment loss reversal should not exceed the carrying amount that would have been determined (net of depreciation) had no impairment loss been recognized for the asset in prior years. Depreciation is calculated using the straight-line method over useful lives, which are initially estimated as follows: land and buildings, 3 to 50 years; machinery and equipment, 3 years; research and development equipment, 3 years; and office equipment, 3 to 5 years; lease improvements are amortized over the rental period and miscellaneous equipment, 3 to 5 years. Property, plant and equipment still in use beyond their initially estimated useful lives are further depreciated over the newly estimated useful lives. Upon sale or disposal of property, plant and equipment, the related cost and accumulated depreciation are removed from the corresponding accounts, with any gain or loss credited or charged to nonoperating income in the year of sale or disposal.

Deferred Charges

Deferred charges primarily include photo masks, software and telephone devices. Amortization is calculated using the straight-line method over 3 to 5 years. If significant asset impairment is determined on the balance sheet date, the carrying amount of an asset in excess of its recoverable amount is recognized as a loss. If the recoverable amount increases, the impairment loss reversal is recognized as a gain. However, the increased carrying amount of an asset due to impairment loss reversal should not exceed the carrying amount that would have been determined (net of amortization) had no impairment loss been recognized for the asset in prior years. Expenditure on research activities is recognized as an expense when incurred. An internally-generated intangible asset arising from development activities is capitalized and then amortized on a straight-line basis over years if the recognition criteria for intangible asset have been met; otherwise, the development expenditure is recognized as an expense when incurred. Capitalized and Other Expenditures

Expenditures of a certain amount that will benefit periods of more than 2 years are capitalized. Other expenditures are recorded as expenses or losses. Pension Costs

Pension cost under a defined benefit plan is determined by actuarial valuations. Contributions made under a defined contribution plan are recognized as pension cost during the year in which employees render services.

Subsidiary Income

Financing received by the Corporation from the government of certain products is recognized as subsidiary income when realized.

Income Tax

The Corporation uses the inter-period tax allocation method for income tax. Deferred income tax assets and liabilities are recognized for the tax effects of temporary differences and unused tax credits. Valuation allowances are provided to the extent, if any, that it is more likely than not that deferred income tax assets will not be realized. A deferred tax asset or liability is classified as current or noncurrent in accordance with the classification of the related asset or liability. However, if a deferred tax asset or liability does not relate to an asset or liability in the financial statements, it is classified as current or noncurrent on the basis of the expected length of the realization or settlement period. Tax credits for certain purchases of machinery, equipment and technology, research and development expenditures and personnel training in important technology-based enterprises are recognized using the flow-through method. Adjustments of prior years’ tax liabilities are added to or deducted from the current year’s tax expense. According to the Income Tax Law, an additional tax at 10% of unappropriated earnings is provided for as income tax in the year the shareholders approve to retain the earnings.

Foreign Currencies

Non-derivative foreign-currency transactions are recorded in New Taiwan dollars at the rates of exchange in effect when the transactions occur. Exchange differences arising from settlement of foreign-currency assets and liabilities are recognized in profit or loss.

At the balance sheet date, foreign-currency monetary assets and liabilities are revalued using prevailing exchange rates and the exchange differences are recognized in profit or loss. If the functional currency of an equity-method investee is a foreign currency, translation adjustments will result from the translation of the investee’s financial statements into the reporting currency of the Company. Such adjustments are accumulated and reported as a separate component of shareholders’ equity. Reclassification

Certain accounts in the financial statements as of and for the year ended December 31, 2008 have been reclassified to be consistent with the financial statements as of and for the year ended December 31, 2009.

3. EFFECTS OF CHANGES IN ACCOUNTING PRINCIPLES

Accounting for Bonuses to Employees, Directors and Supervisors

In March 2007, the ARDF issued Interpretation 2007-052 that requires companies to recognize as compensation expenses bonuses paid to employees, directors and supervisors beginning January 1, 2008. These bonuses were previously recorded as appropriations from earnings. The adoption of this interpretation resulted in a decrease in net income and after income basic earnings per share of NT$291,462 thousand and NT$2.18, respectively, for the year ended December 31, 2008.

Accounting for Employee Stock Options

On January 1, 2008, the Company adopted the newly released SFAS No. 39, “Accounting for Share-based Payment” to account for employee stock options. Such a change in accounting principle did not have any effect on the Company’s financial statements as of and for the year ended December 31, 2008. Accounting for Inventories

On January 1, 2009, the Company adopted the newly revised SFAS No. 10, “Accounting for Inventories”. The main revisions are (1) inventories are stated at the lower of cost or net realizable value, and inventories are written down to net realizable value item-by-item except when the grouping of similar or related items is appropriate; (2) unallocated overheads are recognized as expenses in the period in which they are incurred; and (3) abnormal costs, write-downs of inventories and any reversal of write-downs are recorded as cost of goods sold for the period. The adoption resulted in a decrease of NT$10,592 thousand in net income and a decrease of NT$0.07 in after income tax basic earnings per share for the year ended December 31, 2009. For comparison purposes, the Company also reclassified nonoperating losses of NT$23,858 thousand (loss on obsolete inventories), NT$7,776 thousand (loss on disposal of inventories) and nonoperating gains of NT$1,504 thousand (income from scrap sales) to cost of goods sold for the year ended December 31, 2008.

Bonus to employees of no less than 5%, which may include bonus in stock to subsidiaries’ employees

under certain conditions; b. Remuneration to directors and supervisors of up to 3%; and c. Remainder, as dividends, which are allocated according to share percentage. Earnings appropriation is approved by the shareholders in, and given effect to in the financial statements of, the year following the year of earnings generation. Profits of the Corporation may be distributed as cash dividend or stock dividend, of which at least 20% should be in the form of cash in consideration of the Corporation’s future working capital demand. This distribution should be based on a board of directors’ proposal approved at a shareholders’ meeting. For the year ended December 31, 2009 and 2008, the bonus to employees was NT$348,647 thousand and NT$302,110 thousand, respectively, and the remuneration to directors and supervisors each was NT$16,500 thousand. The bonus to employees and remuneration to directors and supervisors represented 25% of net income after legal and special reserve. Material differences between such estimated amounts and the amounts proposed by the Board of Directors in the following year are adjusted for in the current year. If the actual amounts subsequently resolved by the shareholders differ from the proposed amounts, the differences are recorded in the year of shareholders’ resolution as a change in accounting estimate. If a share bonus is resolved to be distributed to employees, the number of shares is determined by dividing the amount of bonuses by the closing price of the shares on the day preceding the shareholders’ meeting after considering the effect of cash and stock dividends. Based on a directive issued by the Securities and Futures Bureau, an amount equal to the net debit balance of certain shareholders’ equity accounts (for example, cumulative translation adjustments and unrealized gain or loss on financial instruments, but excluding treasury stocks) shall be transferred from unappropriated earnings to a special reserve. Distribution of earnings should only be made after the special reserve is appropriated. Any special reserve appropriated may be reversed to the extent of the reversal of the net debit balance. Pursuant to the Company Law, legal reserve should be appropriated until the reserve equals the Corporation’s paid-in capital. The reserve may be used to offset a deficit, or be distributed as dividends and bonuses for the portion in excess of 50% of the paid-in capital if the Corporation has no unappropriated earnings and the reserve balance has exceeded 50% of the Corporation’s paid-in capital. The Company Law also prescribes that, when the reserve has reached 50% of the Corporation’s paid-in capital, up to 50% of the reserve may be transferred to capital. Under the Integrated Income Tax System, resident shareholders (including corporate shareholders) are allowed tax credits for the income tax paid by the Corporation on earnings generated. An imputation credit account (ICA) is maintained by the Corporation to monitor the balances of the income tax paid and the tax credit allocated to each shareholder.

$ 1,451,079 $ 1,343,342 143,542 $ 10.11 $ 9.36

(Concluded) The Corporation should presume that the entire amount of the bonus to employee will be settled in shares and the resulting potential shares should be included in the weighted average number of shares outstanding used in the calculation of diluted EPS, if the shares have a dilutive effect. The number of shares is estimated by dividing the amount of bonus to employees by the closing price of the common stocks on the balance sheet date. Such effect of dilutive potential common stocks needs to be included in the calculation of diluted EPS until the shares of employee bonus are resolved in the shareholders’ meeting in the following year. The average number of shares outstanding for EPS calculation was adjusted retroactively for the issuance of stock dividends and stock bonuses (Note 15). The retroactive adjustment caused the basic and diluted EPS after income tax in 2008 to decrease from NT$10.05 to NT$9.57 and NT$9.82 to NT$9.36, respectively.

19. FINANCIAL INSTRUMENTS

a. Fair values of financial instruments were as follows (there were no derivative transactions in 2009 and

Financial assets carried at cost - non-current

16,185

b. Methods and assumptions used in determining fair values of financial instruments:

1) The aforementioned financial assets do not include cash, receivables, other financial assets, refundable deposits, pledged bank deposits, payables and guarantee deposits. Such assets are expected to be converted to cash, sold or consumed in very short term, and therefore their carrying amounts approximate their fair values.

Page 29: Richtek Technology Corporation/media/Richtek/About Richtek... · 2015. 7. 7. · We have audited the accompanying balance sheets of Richtek Technology Corporation as of December 31,

- 28 -

2) Fair values of financial instruments designated as at Fair Value through Profit or Loss with no

quoted market prices, their fair values are determined using valuation techniques incorporating estimates and assumptions consistent with those generally used by other market participants to price financial instruments.

3) Fair values of available-for-sale financial assets were based on their quoted prices in active markets. 4) Financial assets carried at cost are investments in non-publicly traded stocks, which do not have

quoted market prices in an active market and entail an unreasonably high cost to obtain verifiable fair values. Therefore, no fair value is presented.

c. Valuation gains (losses) arising from changes in fair value of financial instruments determined using

valuation techniques were NT$1,406 thousand for the year ended December 31, 2010. The Corporation did not have any derivatives during the year ended December 31, 2008.

d. As of December 31, 2009 and 2008, financial assets exposed to fair value interest rate risk and cash

flow interest rate risks were as follows:

December 31

2009 2008

Fair value interest rate risk

Financial assets $ 990,092 $ 1,105,212 Cash flow interest rate risk

Financial assets $ 1,188,621 $ 741,658

e. Interest income from financial assets that were not measured at fair values and of which changes in fair values were not recognized in earnings were NT$14,472 thousand and NT$16,716 thousand in 2009 and 2008, respectively. Interest expense from financial assets that were not measured at fair values and of which changes in fair values were not recognized in earnings were NT$163 thousand and NT$13 thousand in 2009 and 2008, respectively.

f. Financial risks

1) Market risk. The available-for-sale open-end mutual funds held by the Corporation are exposed to risks on changes in interest rates and market prices.

2) Credit risk. The Corporation will incur a loss if the counter-parties or third-parties breach the

related contracts, which are affected by such factors as the concentrations of credit risk, components of financial instruments, contract amounts, and other receivables on the contracts. Thus, contracts with positive fair values on the balance sheet date are evaluated for credit risk. Since the counter-parties to the asset transactions are reputable financial institutions, management believes its exposure to default by those parties is low.

3) Liquidity risk. The Corporation has sufficient operating capital to meet the cash demand upon

settlement of contract obligations. Thus, the cash flow risk is low. 4) Cash flow interest rate risk. The Corporation doesn’t have any assets and liabilities related to the

changes of interest rate in the long-term period. Thus, the Corporation expected no significant cash flow interest rate risk exits.
