Bond Valuation Primary Principle: Value of financial securities = PV of expected future cash flows Bond value is, therefore, determined by the present value of the coupon payments and par value. Interest rates are inversely related to present (i.e., bond) values. The Bond-Pricing Equation Bond Example Consider a U.S. government bond with as 6 3/8% coupon that expires in December 2013. The Par Value of the bond is $1,000. Coupon payments are made semiannually (June 30 and December 31 for this particular bond). Since the coupon rate is 6 3/8%, the payment is $31.875. On January 1, 2009 the size and timing of cash flows are: Bond Example On January 1, 2009, the required yield is 5%. The current value is: Bond Example: Calculator PMT I/Y FV PV N PV 31.875 = 2.5 1,000 – 1,060.17 10 Find the present value (as of January 1, 2009), of a 6 3/8% coupon bond with semi-annual payments, and a maturity date of December 2013 if the YTM is 5%. Bond Example Now assume that the required yield is 11%. How does this change the bond’s price?
