Copyright ©1998 Ian H. Giddy Bonds 9 The Yield l Yield to maturity combines coupons and capital gains - all cash flows. l The yield to maturity on any bond, is the rate that will make the present value of the cash flows from the investment equal to the price of the investment.

Copyright ©1998 Ian H. Giddy Bonds 11 Yield To Maturity (YTM) l YTM is the rate of return investors earn if they buy a bond at a specific price and hold it until maturity l YTM is also the discount rate that causes the bond’s current price to just equal the present value of its interest payments and par value. l Find y such that LHS=RHS:

Copyright ©1998 Ian H. Giddy Bonds 15 Yield Has Problems l Reinvestment assumption: YTM assumes we reinvest at the same yield. l Coupon effect: different bonds with the same maturity, all fairly priced, have different yields. l Callable bonds have no defined maturity.
Copyright ©1998 Ian H. Giddy Bonds 16 Yield of a Zero l Zero-coupon bonds simply pay the principal at maturity, no interest, so find k such that: l Example: 10-year US Treasury zero with face value $1,000 priced at $399.85: k=9.60%
Copyright ©1998 Ian H. Giddy Bonds 17 Better Bond Pricing The method used previously discounts all the bond's cash flows at a single rate, the yield to maturity. But as the yield curve shows, different yields apply to different maturities. The best way to look at the yield for a particular maturity is to find out the yield on a zero-coupon bond for that maturity. Then we can find the PV of each cash flow (coupons & principal) by discounting each cash flow at the corresponding zero-coupon rate. (Or, equivalently, by multiplying by the corresponding discount factor.)
Copyright ©1998 Ian H. Giddy Bonds 18 Better Bond Pricing So we need to find out the z's: the zero- coupon bond yields. There are two ways of doing this. Let us call the zero-coupon rate for each maturity z t. Then the value of a bond should be the sum of the PVs of each of the cash flows.
Copyright ©1998 Ian H. Giddy Bonds 19 The Zero Approach l Use zero-coupon rates to value each cash flow - then add them! l Where can we get the z’s? One place is from the Treasury strip market.

Copyright ©1998 Ian H. Giddy Bonds 21 Bond Lego u To value this bond, break it up into its component cash flows - e.g. 1st coupon of (5 3/4)/2 in Feb 1996, and so on... u Then use zero’s to see what each is worth, and add the total. In general, breaking up a security into its component parts is an excellent path to valuation.

While AT&T eventually regained its former top rating, for the interim period AT&T bond prices fell... and its cost of debt was higher as a result of investors increasing their required rates of return on AT&T bonds.

Giddy Bonds 33 International Capital Markets l The Eurobond Market is the market for bonds issued outside the country of the currency l The Foreign Bond Market is one in which a foreign corporation or government issues bonds in a domestic market in the local currency l An International Equity Market has emerged that allows corporations to sell large blocks of shares simultaneously to investors in several different countries Major Securities Markets

Giddy Bonds 36 Private Placements and Rule 144A The private placement exemption from registration and disclosure is extended to Eurobonds as long as the U.S. investors meet the following requirements: They are large and sophisticated There are only a few investors They have access to information and analysis similar to that which would ordinarily be contained in a registered offering prospectus They are capable of sustaining the risk of losses, and They intend to purchase the bonds for their own investment portfolios, and not for resale.

Giddy Bonds 47 Price Risk of Treasuries Treasuries differ: l Liquidity - traders quote wider bid-ask spreads for illiquid bonds l Duration - sensitivity of price to a change in interest rates - is based on the bond’s coupon levels and maturity date (low duration means less risky) l Convexity - measures how duration changes with a change in rates (high convexity is desirable)
