Valuation Fundamentals Present Value of Future Cash Flows Link Risk & Return Expected Return on Assets Valuation
The Basic Valuation Model P0 = Price of asset at time 0 (today) CFt = Cash flow expected at time t r = Discount rate (reflecting asset’s risk) n = Number of discounting periods (usually years) This model can express the price of any asset at t = 0 mathematically. Value of any financial asset is the PV of future cash flows Bonds: PV of promised interest & principal payments Stocks: PV of all future dividends Patents, trademarks: PV of future royalties Valuation is the process linking risk & return Output of process is asset’s expected market price A key input is the required [expected] return on an asset Defined as the return an arms-length investor would require for an asset of equivalent risk Debt securities: risk-free rate plus risk premium(s) Required return for stocks found using CAPM or other asset pricing model Beta determines risk premium: higher beta, higher reqd return Marginal benefit of owning the asset: right to receive the cash flows Marginal cost: opportunity cost of owning the asset
Valuation Fundamentals: Example Company issues a 5% coupon interest rate, 10‑year instrument with a $1,000 par value Assume annual interest payments Investors in company’s financial instrument receive the contractual rights $50 coupon interest paid at the end of each year $1,000 principal at the end of the 10th year The simplest debt instruments to value are U.S. Treasury securities since there is no default risk. Instead, the discount rate to use, r, is the pure cost of borrowing. Assume you are asked to value two Treasury securities, when rf is 1.75 percent (r = 0.0175): A (pure discount) Treasury bill with a $1,000 face value that matures in three months, and A 1.75% coupon rate Treasury note, also with a $1,000 face value, that matures in three years. For the T-Bill, three months is one-quarter year (n=0.25) For 3-year bond, n = 3 Most U.S. corporate bonds: Pay interest at a fixed coupon interest rate Have an initial maturity of 10 to 30 years, and Have a par value (also called face or principal value) of $1,000 that must be repaid at maturity. Bond’s value has two separable parts: (1) PV of stream of annual interest payments, t=1 to t=10 (2) PV of principal repayment at end of year 10. Can thus also value bond as the PV of an annuity plus the PV of a single cash flow using PVFA and PVF from tables. P0 = C x (PVFA5%,10yr) + Par x (PVF5%,10yr) = $50 (7.7220) + $1,000 (0.6139) = $1,000.00 Bonds with a few cash flows can be valued with Eq 4.1; for bonds with many cash flows, use PVFA/PVF factors, calculator or Excel.
Yield to Maturity (YTM) Estimate of return investors earn if they buy the bond at P0 and hold it until maturity The YTM on a bond selling at par will always equal the coupon rate. -Yield to Maturity (YTM) is the rate of return investors earn if they buy the bond at P0 and hold it until maturity. The YTM on a bond selling at par (P0 = Par) will always equal the coupon interest rate. When P0 Par, the YTM will differ from the coupon rate. YTM is the discount rate that equates the PV of a bond’s cash flows with its price. If P0, CFs, n known, can find YTM Use T-Bond with n=2 years, 2n=4, C/2=$20, P0=$992.43 YTM is the discount rate that equates the PV of a bond’s cash flows with its price.
Bond Premiums and Discounts What happens to bond values if required return is not equal to the coupon rate? The bond's price will differ from its par value P0 < par value r > Coupon Interest Rate DISCOUNT = When r is greater than the coupon interest rate, P0 will be less than par value, and the bond will sell at a discount For Sun, if r >5%, P0 will be less than $1,000 For practice: Value Sun Company, 10-year, 5% coupon rate bond if required return, r =6% and again if r = 4%. Premiums & discounts change systematically as r changes. P0 > par value r < Coupon Interest Rate PREMIUM =
Semi-Annual Interest Payments An example.... Value a T-Bond Par value = $1,000 Maturity = 2 years Coupon rate = 4% r = 4.4% per year = $992.43 Most bonds pay interest semi-annually rather than annually Can easily modify basic valuation formula; divide both coupon payment (C) and discount rate (r) by 2, as in Eq 4.3: In Eq 4.3, C is the annual coupon payment, so C/2 is the semi-annual payment. r is the annual required return, so r/2 is the semi-annual discount rate. n is the number of years, so there are 2n semi-annual payments.
Factors that Affect Bond Prices Time to maturity: bond prices converge to par value (plus final coupon) with passage of time. Interest rates: bond prices and interest rates move in opposite directions. -Yield to Maturity (YTM) is the rate of return investors earn if they buy the bond at P0 and hold it until maturity. The YTM on a bond selling at par (P0 = Par) will always equal the coupon interest rate. When P0 Par, the YTM will differ from the coupon rate. YTM is the discount rate that equates the PV of a bond’s cash flows with its price. If P0, CFs, n known, can find YTM Use T-Bond with n=2 years, 2n=4, C/2=$20, P0=$992.43 Changes in interest rates have larger impact on long-term bonds than on short-term bonds.
Interest Rate Risk What does this tell you about the relationship Whenever r is different from the coupon interest rate, the time to maturity affects bond value (even if the required return remains constant until maturity) The shorter is n, the less responsive is P0 to changes in r. Assume r falls from 5% to 4% For n=8 years, P0 rises from $1,000 to $1,067.33, or 6.73% For n=3 years, P0 rises from $1,000 to $1,027.75, or 2.775% Same relationship if r rises from 5% to 6%, though percentage declines in price less than increases (maximum decline is 100%, increase unlimited) For n=8 years, P0 falls from $1,000 to $937.89, or 6.21% For n=3 years, P0 falls from $1,000 to $973.25, or 2.675% Even if r doesn’t change, premiums and discounts will decline towards par as bond nears maturity. What does this tell you about the relationship between bond prices and yields for bonds with different maturities?
Primary vs. Secondary Markets Primary market: the initial sale of bonds by issuers to large investors or syndicates Secondary market: the market in which investors trade with each other -Yield to Maturity (YTM) is the rate of return investors earn if they buy the bond at P0 and hold it until maturity. The YTM on a bond selling at par (P0 = Par) will always equal the coupon interest rate. When P0 Par, the YTM will differ from the coupon rate. YTM is the discount rate that equates the PV of a bond’s cash flows with its price. If P0, CFs, n known, can find YTM Use T-Bond with n=2 years, 2n=4, C/2=$20, P0=$992.43 Trades in the secondary market do not raise any capital for issuing firms.

Term Structure of Interest Rates Relationship between yield and maturity is called the Term Structure of Interest Rates Graphical depiction called a Yield Curve Usually, yields on long-term securities are higher than on short-term securities. Generally look at risk-free Treasury debt securities Yield curves normally upwards-sloping Long yields > short yields Can be flat or even inverted during times of financial stress The relationship between nominal (observed) and real (inflation-adjusted) interest rates and expected inflation called the Fisher Effect (or Fisher Equation) Fisher said the nominal rate (r) is approximately equal to the real rate of interest (a) plus a premium for expected inflation (i). If real rate equals 3% (a = 0.03) and expected inflation equals 2% (i = 0.02): r a + i 0.03 + 0.02 0.05 5% The true Fisher Effect is multiplicative, rather than additive: (1+r) = (1+a)(1+i) = (1.03)(1.02) = 1.0506; so r = 5.06% What do you think a Yield Curve would look like graphically?

Bond Valuation Bond price equals present value of its coupons and principal. Bond prices are inversely related to interest rates. Bonds could have a number of features: such as convertibility, callability.
