Fixed-Income Cash Flows and Types

Fixed Income

Fixed-Income Contingency Provisions

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 explores various cash flow structures of fixed-income instruments and contrasts the contingency provisions that can benefit either issuers or investors. Key types of bonds discussed include callable bonds, putable bonds, and convertible bonds. Each type has specific features that can influence the cash flows and risks associated with the bond.

Key Concepts:

Callable Bonds

Callable bonds allow the issuer the right to redeem the bond before its maturity at a predetermined price. This feature is beneficial to the issuer, especially if market interest rates fall, allowing them to refinance at lower rates. However, it introduces reinvestment risk for investors.

Putable Bonds

Putable bonds provide the bondholders the right to sell the bond back to the issuer at a predetermined price on specified dates. This feature is advantageous for investors, especially if interest rates rise, allowing them to reinvest at higher rates. It can force the issuer to refinance earlier than planned at potentially higher rates.

Convertible Bonds

Convertible bonds can be exchanged for a predetermined number of the issuer's common shares. This feature is attractive to investors if the issuer's share price appreciates significantly. Convertible bonds typically offer lower yields in exchange for the potential upside in conversion to equity.

Formulas:

Periodic Payment for Amortizing Bond

A=r×Principal1(1+r)NA = \frac{r \times \text{Principal}}{1 - (1 + r)^{-N}}

This formula calculates the periodic payment for an amortizing bond, which includes both interest and principal components.

Variables:
AA:
periodic payment
rr:
periodic interest rate
PrincipalPrincipal:
initial principal amount
NN:
number of periods
Units: currency

Conversion Ratio

Conversion ratio=Convertible bond par valueConversion price\text{Conversion ratio} = \frac{\text{Convertible bond par value}}{\text{Conversion price}}

This ratio determines how many shares a bondholder gets per unit of bond par value when converting a bond into shares.

Variables:
ConvertiblebondparvalueConvertible bond par value:
face value of the convertible bond
ConversionpriceConversion price:
price at which the bond can be converted into equity
Units: dimensionless

Conversion Value

Conversion value=Conversion ratio×Current share price\text{Conversion value} = \text{Conversion ratio} \times \text{Current share price}

This value represents the worth of the bond if converted into shares at the current market price.

Variables:

number of shares received per unit of bond par value

current market price of the issuer's shares

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

A=r×Principal1(1+r)NA = \frac{r \times \text{Principal}}{1 - (1 + r)^{-N}}

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:
AA:
Periodic payment amount
rr:
Market interest rate per period
PrincipalPrincipal:
Principal amount of loan or bond
NN:
Number of payment periods
