History of U.S. Mortgage Market
1930s—Great Depression led to 30-year fixed rate mortgage
1932—Federal Home Loan Bank system for thrift and FSLIC to insure depositors. Major source of residential mortgages until 1970s. Role greatly reduced with thrift crisis of 1980s.
1934—FHA—established to insure high LTV loans
1938—FNMA—established to purchase & hold FHA loans
1968—FNMA became private corporation—split into FNMA & GNMA
1970—First GNMA pass-through security
1970—FHLMC chartered as second GSE
1971—FHLMC issued first pass-through
1983—FHLMC issued first sequential pay CMO
71-29-06 NY (tom).ppt
Mortgage Types
Fixed-rate— 15-year— 30-year
Adjustable-rate— Treasury— LIBOR
Hybrid (fixed period, then adjustable period)— 3/1s— 5/1s
Balloon (30-year amortization, then balloon payment)— 5-year— 7-year
81-29-06 NY (tom).ppt
Securitization Process or (Conversion of Mortgage Collateral into Mortgage-Backed Securities)
Securities issued by a bankruptcy remote trust not an originator
Securities payment comes from cash-flow of underlying collateral, not payment from originator of loans.
If originator of loans goes into bankruptcy, does not impact cash-flow to security holders
Credit enhancement:— 3rd party guarantee—
– GNMA, FHLMC, FNMA for agencies– AAA monoline for non-agency
— Internal to deal—– Excess spread– Overcollateralization (OC) – Subordinated classes
91-29-06 NY (tom).ppt
Prepayments—The Key to Agency MBS Valuation
Homeowner has right to call his loan at any time.
MBS = Treasury + Short a “Call”
Very few prepayment penalties in Agency MBS
When rates decline, homeowners prepay faster
101-29-06 NY (tom).ppt
Prepayment Terminology
SMM = Single Monthly Mortality Rate
= Actual Principal Payment – Scheduled Principal Payment
Beginning Principal
CPR = SMM Annualized
PSA = Public Securities Association Standard Prepayment Ramp

Calculation of Prepayment Option Cost
OAS approach
1. Simulate 500 interest rate paths.
2. Calculate prepayments on each path.
3. Calculate yield spread of MBS to LIBOR (Treasury) curve so average price across all paths just equals price of MBS.
4. This is the expected yield pick-up to LIBOR (Treasury) curve, after adjusting for prepayment risk.

Enhancement Reflects Collateral Differences
In Non-Agency MBS, credit enhancement structures come mainly in two flavors
— “Six-pack” structures where several locked-out subs provide credit enhancement. Mainly used on Jumbos and Alt-As
— Excess-spread / Over-collateralization structures, where locked-out subs are complemented by excess interest from the collateral to cover losses. Mainly used in Subprime, High-LTV, Scratch & Dent, sometimes Alt-A

Note: MBS are backed by 1-4 family mortgage loans. Agency CMO/REMICs are backed by FNMA, FHLMC or GNMA collateral. Starting January 2001, Non-Agency MBS include private-label jumbo and Alt-A transactions, plus mortgage-related ABS, including subprime HEL, second liens, HELOCs, high LTV loans and manufactured housing loans. ABS data prior to 2001 include some mortgage-related collateral.

Factors Behind Growth in Subprime HEQ Issuance
More subprime borrowers— Increase in consumer debt burden
Greater % of subprime borrowers taking out mortgages— Aggressive marketing programs— Internet access
Expanded definition of subprime— Includes more Alt-A
Securitizers accounting for greater share of subprime lending— More aggressive lending— Rapid expansion into new geographic areas
Consumers shifting installment debt to mortgage debt
Lower rates = Increased rate refis
Greater housing inflation = Increased cash-out refis
