Bonds

Study guide: Exam FM-2

A bond is a fixed-income debt instrument in which an issuer (borrower) promises to pay the bondholder (lender) periodic Coupon payments and to return the Face Value (par value) at maturity. Key bond terms:

  • Face Value — Principal amount repaid at maturity (par value)

  • Coupon Rate — Annual interest rate applied to face value to set coupon payments

  • Coupon — Periodic interest payment = Face Value × Coupon Rate / payments per year

  • Yield Rate — Rate of return actually earned by the bondholder (may differ from coupon rate)

  • Price — Present value of all future cash flows at the yield rate

  • Term of Bond — Time from issue to maturity

  • Book Value — Amortized value of the bond at any point during its term

  • The basic bond price formula: P = Fr \cdot a_{\overline{n}|j} + C \cdot v^n where F = face value, r = coupon rate per period, C = redemption value, n = number of coupons, j = yield rate per period.

Bond Pricing A 1{,}000 face value 5-year bond with 6% annual coupons is priced at a yield of 7%.

Answer P = 60 \cdot a_{\overline{5}|7\%} + 1000v^5 = 60(4.1002) + 1000(0.712986) = 246.01 + 712.99 = 959.00. The bond is redeemed at par (C = F = 1{,}000), so it sells at a discount (price below the redemption value) because its 6% coupon rate is below the 7% yield rate.
