  1. Valuing Debt FINA 7330 Corporate Finance Lecture 13

  2. Topics Covered • Real and Nominal Rates of Interest • Term Structure and Yield to Maturity • The Term Structure and Bond Pricing • Theories of the Term Structure

  3. Irving Fisher and the Theory of Interest Rates • The Real Interest Rate is determined by the real economic activity and demographics of the Economy (The Demand and Supply for Capital) • The Nominal Interest Rate is the real rate adjusted for inflation 1 + R = (1 + r) * (1 + E[inf.])

  4. U.K. Rates

  5. Inflation and Interest Rates • Note the Real Rate tends to be rather stable but the Nominal Rate is more volatile. What makes it more volatile? The Expected inflation rate! • Does the theory fit the facts? We can’t measure Expected inflation, but assume actual inflation follows expected inflation closely then:

  6. The Return on US Treasury Bills and the Inflation rate (1953-2003)

  7. Normal Yield Curve

  8. Current Yield Curve

  9. Treasury Yields • Maturity Yield • 12/13/2006 5.17 • 12/13/2007 5.03 • 12/12/2008 4.76 • 12/12/2009 4.66 • 12/12/2011 4.60 • 12/11/2013 4.60 • 12/10/2016 4.61 • 12/8/2026 4.80 • 12/5/2036 4.71

  11. The Term Structure and Bond Prices Consider Two Year Treasury (3.125s October 08) Price is 97:03 = 97.09 4/07 10/07 4/08 10/08 1.5625 1.5625 1.5625 101.5625 YTM:

  12. The Term Structure and Bond Prices Consider Two Year Treasury (3.125s October 08) Price is 97:03 4/07 10/07 4/08 10/08 1.5625 1.5625 1.5625 101.5625 YTM: 4.66

  13. But consider the term structure Two Year Treasury (3.125s October 08) Price is 97:03 4/07 10/07 4/08 10/08 1.5625 1.5625 1.5625 101.5625 Strip Yields 4.94 4.87 4.50 4.64 PV 1.5248 1.4899 1.4616 92.7551 Value = 97.23

  14. Bond Prices and Yields Price Yield

  15. Duration Calculation

  16. Risk and Duration • The relationship between Risk and Duration • Volatility = Duration/(1 + YTM) • So in example, D = 3.714, YTM = 2.75% Volatility = 3.615% % Change Value at 3.25% 1083.14 -1.78 Value at 2.25% 1123.04 1.83 Volatiltiy 3.61%

  17. Duration Example (Bond 1) Calculate the duration of our 6 7/8 % bond @ 4.9 % YTM • Year CF PV@YTM % of Total PV % x Year • 1 68.75 65.54 .060 0.060 • 2 68.75 62.48 .058 0.115 • 3 68.75 59.56 .055 0.165 • 4 68.75 56.78 .052 0.209 • 5 1068.75 841.39 .775 3.875 • 1085.74 1.00 Duration4.424

  18. Spot/Forward rates Example rn is the “Spot Rate” = the annualized yield on a discount bond making 1 payment n years in the future fn is the “Forward Rate”= the implied yield on a one year discount bond issued n-1 years in the future.

  19. Spot and Forward Rates • In general: • (1+ rn) = (1 + r1)(1 + f2)(1 + f3)…)(1 + fn)

  20. Spot/Forward rates Example What is the 3rd year forward rate? 2 year zero treasury YTM = 4.63 3 year zero treasury YTM = 4.57

  21. Spot/Forward rates • Example What is the 3rd year forward rate? 2 year zero treasury YTM = 4.63 3 year zero treasury YTM = 4.57 Answer (1+r3)3 = (1+r2)2(1+f3) (1+r3)3/(1+r2)2 = (1 + f3) 1.1435/1.0947 = 1.0445 f3 = 4.45%
