Q

Credit tranching vs. Time Tranching (Typical structures of securitization)

A
Credit tranching: credit losses are first absorbed by the tranche with the lowest priority, and after that by any other suboridinated tranches, in order (used when there are difference bond classes)
Time tranching refers to security classes that receive the principal payments from underlying securities sequentially as each prior tranche is repaid in full (used when all bonds are part of the same bond class for example A rated). 

Time tranching redistributes prepayment risk while credit tranching redistributes credit risk

A

Q

Describe the two types of prepayment risk for securities

A
  1. Contraction risk: Mortgage rates drop, while refinancing and prepayments increase (reinvest cash flows at lower rates)
  2. Extension risk: mortgage rates increase, while refinancing and prepayments drop (don’t have cash flow to reinvest at higher rates)

Q

Why is contraction and extension bad?

A

Contraction: You have to reinvest when mortgage rates are dropping because borrowers are increasing their prepayments
Extension: You don’t have the cash flow to invest at the higher mortgage rates because borrowers are prepaying less

16
Q

Sequential pay CMO

A

All scheduled principal payments and prepayments are paid to each tranche in sequence until that tranche is paid off (bond class 1 gets paid first). The first tranche is to be paid principal and has the most contraction risk and the last tranche to be paid principal has the most extension risk.

17
Q

In a CMO, which tranche has contraction risk and which one has extension risk?

A

The first tranche has the most contraction risk while the last tranche has the most extension risk

18
Q

Planned amortization class (PAC)

A

A planned amortization class (PAC) CMO has PAC tranches that receive predictable cash flows as long as the prepayment rate remains within a predetermined range (offers both contraction and extension risk due to a lower and upper PSA)

19
Q

Support Tranche

A

A class or tranche in a CMO that protects the PAC tranche from prepayment risk. Support tranches get any money that is over the principal payment.

20
Q

Prepayment risk

A

The uncertainty that the timing of the actual cash flows will be different from the scheduled cash flows as set forth in the loan agreements due to the borrowers ability to alter payments, usually to take advantage of interest rate movements.

21
Q

Extension risk

A

The risk that when interest rates rise, fewer prepayments will occur because homeowners are reluctant to give up the benefits of a contractual interest rate that now looks low. As a result, the security becomes longer in maturity than anticipated at the time of purchase.

22
Q

Contraction risk

A

The risk that when interest rates decline, the security will have a shorter maturity than was anticipated at the time of purchase because borrowers refinance at the new, lower interest rates.

23
Q

Commercial Mortgage Backed Securities (CMBS)

A

Pools of commercial mortgages backed by mortgages on income-producing real estate properties. Because commercial mortgages are non-recourse loans, analysis of CMBS focuses on credit risk of the properties. CMBS are structured in tranches with credit losses absorbed by the lowest priority tranches in sequence.

24
Q

Call (prepayment) protection includes

A
  1. Prepayment lockout periods (2-5 years)
  2. Defeasance
  3. Prepayment penalty points
  4. Yield maintenance charges
25
Q

Main difference between RMBS and CMBS

A

RMBS allows prepayments while CMBS does not

26
Q

Asset-backed securities

A

A type of bond issued by a legal entity called a special purpose entity (SPE) on a collection of assets that the SPE owns. Also, securities backed by receivables and auto loans other than mortgages.

27
Q

floating-rate tranches

A

Type of tranch for Collateralized mortgage obligations where collateral pays a fixed rate. The CMO still get a fixed $ interest amount but principle amount is split into a floating and inverse floating portion.

28
Q

Prime Loans

A

Mortgages with higher LTV ratios made to borrowers with higher credit quality

29
Q

Collateralized Debt Obligations

A

Generic term used to describe a security backed by a diversified pool of one or more debt obligations. Usually involves an asset (collateral) manager

30
Q

Collateral Manager

A
