Fixed-Income Cash Flow Structures
Learning Outcome Statement:
describe common cash flow structures of fixed-income instruments and contrast cash flow contingency provisions that benefit issuers and investors
Summary:
This LOS covers various cash flow structures of fixed-income instruments, including amortizing debt, variable interest debt, zero-coupon structures, and deferred coupon structures. It explains how these structures impact the payments made over the life of the bond and how they benefit either the issuer or the investor.
Key Concepts:
Amortizing Debt
Amortizing debt involves periodic retirement of a portion of the principal along with interest payments over the life of the instrument, reducing credit risk due to the gradual decrease in the borrower's liability.
Variable Interest Debt
Variable interest debt adjusts the interest payments based on a market reference rate plus a credit spread. This structure can benefit investors during periods of rising interest rates but also carries credit risk.
Zero-Coupon Structures
Zero-coupon bonds do not make periodic interest payments but are issued at a discount and repay the principal at maturity. The investor's return is the difference between the purchase price and the principal.
Deferred Coupon Structures
Deferred coupon bonds delay interest payments until a specified future time, usually to conserve cash for the issuer. These bonds typically carry higher coupons post-deferral to compensate for the initial period without interest payments.
Formulas:
Periodic Payment for Amortizing Loan
This formula calculates the periodic payment for an amortizing loan, which includes both principal and interest components. The payment amount is fixed throughout the term of the loan.
Variables:
- :
- Periodic payment amount
- :
- Market interest rate per period
- :
- Principal amount of loan or bond
- :
- Number of payment periods
