All rights reserved. 5-2 Valuation of Bonds and Stock First Principles: –Value of financial securities = PV of expected future cash flows To value bonds and stocks we need to: – Estimate future cash flows: Size (how much) and Timing (when) – Discount future cash flows at an appropriate rate: The rate should be appropriate to the risk presented by the security.

4. McGraw-Hill/Irwin Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved. 5-3 5.1Definition and Example of a Bond A bond is a legally binding agreement between a borrower and a lender: –Specifies the principal amount of the loan. –Specifies the size and timing of the cash flows

5. McGraw-Hill/Irwin Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved. 5-4 5.2How to Value Bonds Identify the size and timing of cash flows. Discount at the correct discount rate. –If you know the price of a bond and the size and timing of cash flows, the yield to maturity is the discount rate.

All rights reserved. 5-7 Level-Coupon Bonds Information needed to value level-coupon bonds: –Coupon payment dates and time to maturity (T) –Coupon payment (C) per period and Face value (F) –Discount rate Value of a Level-coupon bond = PV of coupon payment annuity + PV of face value

All rights reserved. 5-8 5.3Bond Concepts 1.Bond prices and market interest rates move in opposite directions. 2.When coupon rate = YTM, price = par value. When coupon rate > YTM, price > par value (premium bond) When coupon rate < YTM, price < par value (discount bond) 3.A bond with longer maturity has higher relative (%) price change than one with shorter maturity when interest rate (YTM) changes. All other features are identical. 4. A lower coupon bond has a higher relative price change than a higher coupon bond when YTM changes. All other features are identical.

When the YTM = coupon, the bond trades at par. When the YTM > coupon, the bond trades at a discount.

14. McGraw-Hill/Irwin Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved. 5-13 Case 1: Zero Growth Assume that dividends will remain at the same level forever  Since future cash flows are constant, the value of a zero growth stock is the present value of a perpetuity:

15. McGraw-Hill/Irwin Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved. 5-14 Case 2: Constant Growth Since future cash flows grow at a constant rate forever, the value of a constant growth stock is the present value of a growing perpetuity: Assume that dividends will grow at a constant rate, g, forever. i.e....

16. McGraw-Hill/Irwin Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved. 5-15 Case 3: Differential Growth Assume that dividends will grow at different rates in the foreseeable future and then will grow at a constant rate thereafter. To value a Differential Growth Stock, we need to: –Estimate future dividends in the foreseeable future. –Estimate the future stock price when the stock becomes a Constant Growth Stock (case 2). –Compute the total present value of the estimated future dividends and future stock price at the appropriate discount rate.

17. McGraw-Hill/Irwin Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved. 5-16 5.5 Estimates of Parameters in the Dividend-Discount Model The value of a firm depends upon its growth rate, g, and its discount rate, r. –Where does g come from? –Where does r come from?

18. McGraw-Hill/Irwin Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved. 5-17 Where does g come from? g = Retention ratio * Return on retained earnings Net investment will be positive only if some earnings are retained.

19. McGraw-Hill/Irwin Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved. 5-18 Where does r come from? One of the methods: r = Div/P 0 + g The discount rate can be broken into two parts. –The dividend yield –The growth rate (in dividends) In practice, there is a great deal of estimation error involved in estimating r.

20. McGraw-Hill/Irwin Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved. 5-19 A Healthy Sense of Skepticism –Estimate of g is based on a number of assumptions: return on reinvestment future retention ratio –Some financial economists suggest calculating the average r for an entire industry.

21. McGraw-Hill/Irwin Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved. 5-20 Two polar cases Case1: A firm paying no dividend, and going from no dividends to a positive number of dividends Case2: An analyst whose estimate of g for a particular firm is equal to or above r must have made a mistake.

22. McGraw-Hill/Irwin Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved. 5-21 5.6Growth Opportunities Imagine a company with a level stream of earnings per share in perpetuity The company pays off these earnings out to stockholders as dividends. Hence. EPS = Div (Cash cow) It’s value equals EPS/r = Div/r

23. McGraw-Hill/Irwin Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved. 5-22 Growth opportunities are opportunities to invest in positive NPV projects. Suppose the firm retains the entire dividend at date 1 in order to invest in a particular capital budgeting project Stock Price after Firm Commits to the New Project: EPS/r + NPVGO

24. McGraw-Hill/Irwin Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved. 5-23 Two conditions must be met in order to increase value: –Earnings must be retained so that projects can be funded. –The projects must have positive net present value.

25. McGraw-Hill/Irwin Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved. 5-24 Example: EPS/r + NPVGO = 【〔 $1,000,000/1.1 〕 + 〔 $1,000,000/(1.1) 2 〕 +…+ 〔 $1,000,000/(1.1) n 〕】 + 【〔 -$1,000,000+($210,000/0.1) 〕 /1.1 】 = 〔 $1,000,000/0.1 〕 + 〔 -$1,000,000+ $2,100,000 〕 /1.1 = $10,000,000+$1,000,000 = $11,000,000 The price per share: $11,000,000/100,000 = $110

All rights reserved. 5-25 Growth in Earnings and Dividends versus Growth Opportunities A policy of investing in projects with negative NPVs rather than paying out earnings as dividends will lead to growth in dividends and earnings, but will reduce value.

27. McGraw-Hill/Irwin Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved. 5-26 Dividends or Earnings: Which to discount? Dividends, or would ignore the investment that a firm must make today in order to generate future returns.

28. McGraw-Hill/Irwin Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved. 5-27 The No-Dividend Firm A firm with many growth opportunities faces two choices: pays out dividends now, or forgoes dividends now and makes investments. The actual application of the dividend discount model is difficult for firms of this type.

29. McGraw-Hill/Irwin Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved. 5-28 5.7The Dividend Growth Model and the NPVGO Model (Advanced) A steady growth in dividends results from a continual investment in growth opportunities, not just in a single opportunity.

30. McGraw-Hill/Irwin Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved. 5-29 Example C has EPS of $10 at the end of the first year, a dividend-payout ratio of 40%, a discount rate of 16%, and a return on its retained earnings of 20%.

31. McGraw-Hill/Irwin Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved. 5-30 Solution The Dividend-Growth Model The NPVGO Model –Value Per Share of a Single Growth Opportunities -$6 + $1.20/0.16 = $1.5 –Value Per Share of All Opportunities NPVGO = $1.50/(0.16-0.12)=$37.50 –Value Per Share if Firm Is a Cash Cow Div/r = $10/0.16 = $62.50 –Summation $37.5 + $62.5 = $100.0

All rights reserved. 5-31 5.8 Price-Earnings Ratio (P/E ratio) P (Price per share) = EPS/r + NPVGO P/E = 1/r + NPVGO / EPS The market is merely pricing perceptions of the future, not the future itself. It implies that P/E ratio is a function of: growth opportunities, risk, and the choice of accounting methods.
