  1. Chapter 10 Bond Prices and Yields

  2. Bond Characteristics • Face or par value • Coupon rate • Zero coupon bond • Compounding and payments • Accrued Interest • invoice price versus quoted price • Indenture

  3. Provisions of Bonds • Secured or unsecured (debenture) • Call provision • refunding • call price • deferred callable bond • coupon rates and promised ytm at issuance

  4. Provisions of Bonds • Convertible provision • conversion ratio • market conversion value • conversion premium • coupon rate & ytm at issuance • Convertible example • conversion ratio = 25 • market price of stock = $42 • callable bond price = $1150

  5. Provisions of Bonds • Put provision (putable bonds) • coupon rate & ytm at issuance • Floating rate bonds • changing credit condition of issuer • Sinking funds

  6. Other innovations • Pay in kind bonds (pik) • reverse floaters • indexed bonds (TIPS -Treasury Inflation Protection bonds)

  7. Default Risk and Ratings • Rating companies • Moody’s Investor Service • Standard & Poor’s • Duff and Phelps • Fitch • Rating Categories • Investment grade • Speculative grade

  8. Factors Used by Rating Companies • Coverage ratios • Leverage ratios • Liquidity ratios • Profitability ratios • Cash flow to debt

  9. Protection Against Default • Sinking funds • Subordination of future debt • Dividend restrictions • Collateral • mortgage bond • equipment obligation • collateral trust

  10. Bond Pricing PB = Price of the bond Ct = interest or coupon payments T = number of periods to maturity y = semi-annual discount rate or the semi-annual yield to maturity

  11. 20  1 1 = + P 40 1000 B t 20 (1+.03) (1+.03) t =1 Solving for Price: 10-yr, 8% Coupon Bond, Face = $1,000 PB = $1,148.77 Ct = 40 (SA) P = 1000 T = 20 periods r = 3% (SA)

  12. Bond Prices and Yields Prices and Yields (required rates of return) have an inverse relationship • When yields get very high the value of the bond will be very low • When yields approach zero, the value of the bond approaches the sum of the cash flows

  13. Prices and Coupon Rates Price Yield

  14. Yield to Maturity YTM = the discount rate that makes the present value of the bond’s promised payments equal to its price. Bond is priced at $1067.95, it has a coupon rate of 9% paid semiannually, a par value of $1000, and 10 years to maturity. Find the bond’s ytm. What is the current yield? Bond is priced at $945.40 , it has a coupon rate of 6% paid semiannually, a par value of $1000, and 14 years to maturity. Find the bond’s ytm. What is the current yield?

  15. YTM versus current yield versus coupon rate • Bond selling at par • coupon = YTM = current yield • Bond selling at a premium • coupon > current > YTM • Bond selling at a discount • coupon < current < YTM

  16. Yield to call (YTC) • Similar to YTM, but use time to first call date and call price as future value. • Bond with 15 years to maturity, par of $1000, a coupon rate of 8% (paid semiannually), price of $1025, callable in 5 years at $1080. Find YTC.

  17. Realized compound yield versus yield to maturity • YTM will equal the realized return over the life of the bond if all payments are reinvested at an interest rate equal to the bond’s yield. • Consider a bond with 10 years to maturity, coupon rate of 9 percent paid annually, and a price of $1067.10.

  18. Realized compound yield (RCY) versus yield to maturity (YTM) • Consider a bond with 10 years to maturity, coupon rate of 9 percent paid annually, and a price of $1067.10. • What is its ytm? • Realized compound yield if you reinvest at ytm? • RCY if you reinvest at 3 percent?

  19. Holding period return (HPR) versus YTM. • Consider a bond with 10 years to maturity, coupon rate of 9 percent paid annually, and a price of $1067.10. Note: ytm = 8% • Suppose you hold the bond one year and interest rates decline to 7 percent. Calculate your HPR. • Suppose instead that rates had risen to 9 percent. What is your HPR?

  20. Original Issue Discount (OID) • Consider a 10 year Treasury strip with a yield of 5 percent and face of $10,000. • Price = $6,139.13 • After one year (yield = 5%) • P = $6,446.09 • Difference = implicit interest = $306.96 • If you sold the strip for $6,500, then you would have interest income of $306.96 and capital gain of $53.91

  21. Term Structure of Interest Rates • Relationship between yields to maturity and maturity • Yield curve - a graph of the yields on bonds relative to the number of years to maturity • Usually Treasury Bonds • Have to be similar risk or other factors would be influencing yields

  22. Yield Curves Yields Upward Sloping Downward Sloping Maturity

  23. Theories of Term Structure • Expectations • Liquidity Preference • Upward bias over expectations • Market Segmentation • Preferred Habitat
