Fixed Income Flashcards
Rollover risk
Rollover risk is the risk that an issuer who relies on the commercial paper market as a funding source may not be able to issue new commercial paper when an outstanding issue matures.
Full price of bond
Full price of bond = clean price + accrued interest
Sinking fund provision
A sinking fund provision requires the issuer to retire a portion of a bond issue at specified times during the bonds’ life.
Structure subordination
In a holding company structure, a subsidiary’s debt covenants may prohibit the transfer of cash or assets to the parent until after the subsidiary’s debt is serviced. The parent company’s bonds are thus effectively subordinated to the subsidiary’s bonds.
Key characteristics of RMBS
- Pass-through rate, the coupon rate on the RMBS. - Weighted average maturity (WAM) and weighted average coupon (WAC) of the underlying pool of mortgages. - Conditional prepayment rate (CPR), which may be compared to the Public Securities Administration (PSA) benchmark for expected prepayment rates.
Collateralized mortgage obligations (CMOs)
Collateralized mortgage obligations (CMOs) are collateralized by pools of residential MBS. CMOs are structured with tranches that have different exposures to prepayment risks.
Sequential-pay collateralized mortgage obligations (CMOs)
In a sequential-pay CMO, all scheduled principal payments and prepayments are paid to each tranche in sequence until that tranche is paid off. The first tranche to be paid principal has the most contraction risk and the last tranche to be paid principal has the most extension risk.
Planned amortization class (PAC) collateralized mortgage obligations (CMOs)
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, and support tranches that have more contraction risk and more extension risk than the PAC tranches.
Underwritten offering
Best effort offering
Shelf registration
- Underwritten offering: Investment banks buy entire issue, sell to public.
- Best efforts offering: Investment banks act as brokers.
- Shelf registration: Register entire issue with regulators but sell over a period of time.
Two components of interest rate risk
- Reinvestment risk: Bond investors with long horizons are more concerned with reinvestment risk
- Market price risk: Bond investors with short horizons are more concerned with market price risk
Yield Spread
- G-spread: Basis points above government yield
- I-spread: Basis points above swap rate
- Z-spread: Accounts for shape of yield curve. It is the single spread that, when added to each spot rate, produces a bond value that is equal to the current market value of a bond.
- Option-adjusted spread: Adjusts Z-spread for effects of embedded options.
current yield
Current yield = annual coupon / price
simple yield
simple yield = current yield + amortization
where current yield = annual coupon / price
