CMOs
Bond classes created by redirecting the cash flows of mortgage-related products so as to mitigate prepayment risk.
Pay-through structure: there are more than one class of bondholders with the same level of credit priority
Tranches: different bond classes

Sequential-Pay Tranches
The collateral for the hypothetical CMO is a hypothetical pass-through with total par value of $400 million and the following characteristics :
(1) The pass-through coupon rate is 7.5%
(2) WAC=8.125%
(3) WAM=357 month
(4) 165PSA

each tranche on the basis of the amount of principal outstanding at the beginning of the period
2. For disbursement of principal payments: Disburse principal prepayments to tranche A until it is paid off completely. After tranche A is paid off completely, disburse principal payments to tranche B until it is paid off completely. After … After tranche C is paid off completely, disburse principal payments to tranche D until it is paid off completely.

Principal Payments under PAC
Disburse principal payments to tranche P based on its schedule of principal repayments. Tranche P has priority with respect to current and future principal payments to satisfy the schedule. Any excess principal payments in a month over the amount necessary to satisfy the schedule for tranche P are paid to tranche S. When tranche S is paid off completely, all principal payments are to be made to
tranche P regardless of the schedule.

Support Bonds
Bodyguards for the PAC bondholders
Can be partitioned into classes, I.e, bodyguards have ranks and titles, too.
BUS424 (Ch 12, 14, 15, 16) 14
Objective
To eliminate the contraction risk and the extension risk
Contraction risk: when interest rate goes down
Extension risk: when interest rate goes up
BUS424 (Ch 12, 14, 15, 16) 15
Series of PAC Bonds
• Combination of PAC and sequential-pay CMO• Page 290• At different prepayment rate, the average lives of
6 PAC bonds are different (ex 12-11).– What do you see from there?
BUS424 (Ch 12, 14, 15, 16) 16
TACOne-side prepayment protection.
Has a single PSA rate from which the schedule of principal repayment is protected
Typically protected when prepayment is high, thus avoid contraction risk.

Credit Risk and Tax Treatment of CMOs
Agency CMOs
Nonagency CMOs
Interest and principal payments are not taxable.

Stripped Mortgage-Backed Securities
Principal-only (PO) securitieswhen current mortgage rate < coupon rate, prepayment speeds up. price goes up
when current mortgage rate > coupon rate, price drops.
Interest-only (IO) securitiescurrent mortgage rate < coupon rate, mixed
Exhibit 12-145(page 297)
CMO strips: one class in CMO structure could be PO or IO.

Commercial Mortgage-Backed Securities(ch14)
Commercial mortgage loans are for income-generating properties, including
• Multifamily properties (apartment buildings)• Office building• Industrial properties• Shopping centers• Hotel• Health care facilities
BUS424 (Ch 12, 14, 15, 16) 20
Characteristics of Commercial Mortgage Loans
Commercial mortgage loans are non-recourse loans – lenders can only look to the income-producing property backing the loan for interest and principal repayments.
Performance• Debt-to-service coverage ratio – page 331• Loan-to-value ratio – page 331Prevent from prepayment – page 332
BUS424 (Ch 12, 14, 15, 16) 21
CMBS
A commercial mortgage-backed security is a security backed by one or more commercial mortgage loans. It can be issued by agency or none agency backed.
• Single borrower/multi-property deals• Multi-borrower deals
BUS424 (Ch 12, 14, 15, 16) 22
Asset-backed Securities –
Chapter 15• Securities created by pooling loans other than first-lien mortgage loans are referred to as asset-backed securities.
• 4 biggest sectors
• Credit card receivables
• Auto loans
• Home-equity loans
• Manufactured housing loans
BUS424 (Ch 12, 14, 15, 16) 23
Creation of an ABS1. Granting a loan
– Underwriting standards– Originator of a loan
2. Securitization process– Special purpose vehicle (SPV): the ABS issuer
—Legal implication: rating of ABS will be independent of the originator (page 356)
– Conduit: the party who buys the loans and sell them to SPV.
3. Credit enhancements– External – bond insurance (page 358)– Internal
BUS424 (Ch 12, 14, 15, 16) 24
Roles of SPV
1. The potential for reducing funding costs (page 358)
2. To diversify funding sources
3. To accelerate earnings for financial reporting purposes
4. For regulated entities, potential relief from capital requirements.
BUS424 (Ch 12, 14, 15, 16) 25
Credit Enhancement of ABS
External credit enhancement
Guaranty from third party like bond insurance
Internal credit enhancement
Cash flow waterfall (or simply waterfall)
-- cash flow to senior bondholders first, then to lower priority classes.

-- make sure if the collateral’s cash flows match the payments that must be made to satisfy the issuer’s obligtions.

Credit Card Receivable-Backed Securities
This is an example of ABS -- Page 366.
Credit card issuers have receivables• financing charges collected, fees and
principals.
IBs use the future cash flows from credit card receivables as collaterals to issue ABS or CDOs
BUS424 (Ch 12, 14, 15, 16) 29
Collateralized Debt Obligations (chapter 16, page 382)
A security backed by a diversified pool of one or more of the following types of debt obligations
• U.S. domestic investment-grade and high-yield corporate bonds
• U.S. domestic bank loans• Emerging market bonds• Special situation loans and distressed debt• Foreign bank loans• Asset-backed securities• Residential and commercial mortgage-back securities

issuance of debt obligations.
Structure of debt obligationsSenior tranchesMezzanine tranchesSubordinate/equity tranches
BUS424 (Ch 12, 14, 15, 16) 31
Categories of CDOs
Arbitrage transactionswhen the motivation of the sponsor is to earn the spread between the yield offered on the collateral and the payments made to the various tranches
Balance sheet transactionswhen the motivation is to remove debt instruments (primarily loans) from its balance sheet, typically financial institutions such as banks seeking to reduce their capital requirement specified by bank regulators
BUS424 (Ch 12, 14, 15, 16) 32
Cash vs Synthetic Structures
Synthetic CDO structures involve the use of credit derivatives.
BUS424 (Ch 12, 14, 15, 16) 33
Arbitrage Transactions
Tranche Par Value Coupon Value Coupon Rate
Senior $80,000,000 Floating LIBOR+70 basis points
Mezzanine $10,000,000 Fixed Treasury rate + 200 basis point
Subordinate/Equity $10,000,000
Create an arbitrage CDO is whether a structure can offer a competitive return for the subordinate/equity tranche as below:
BUS424 (Ch 12, 14, 15, 16) 34
AssumptionsThe collateral of the CDO:• bonds that all mature in 10 years• The coupon rate for every bond is a fixed rate• The fixed rate at the time of purchase of cash bond is the 10 year
treasury plus 400 basis points
To finance the senior tranche, • collateral manager enters into an interest-rate swap with another party
with a notional principal of $80 million in which it agrees to do the following:
• Pay a fixed rate each year equal to the 10-year Treasury rate plus 100 basis points
• Receive LIBOR
BUS424 (Ch 12, 14, 15, 16) 35
Cash flowsAssuming the 10-year rate at the time the CDO is issued is 7%.• Interest received from collatoral:• Interest to senior tranche:• Interest to mezzanine tranche:• Interest to swap counterpart: • Interest received from swap counter partAs a result,• Total interest received:• Total interest paid:• Net interest
BUS424 (Ch 12, 14, 15, 16) 36
Synthetic CDOs
In a synthetic CDO, the collateral absorbs the economic risk associated with specified assets but does not have legal ownership of those assets
Requires the use of CDS
