MBA 2006 DDM |3|3 DDM: one-year holding period Review: valuing a 1-year 4% coupon bond Face value:€ 50 Coupon:€ 2 Interest rate 5% How much would you be ready to pay for a stock with the following characteristics: Expected dividend next year: € 2 Expected price next year: €50 Looks like the previous problem. But one crucial difference: –Next year dividend and next year price are expectations, the realized price might be very different. Buying the stock involves some risk. The discount rate should be higher. Bond price P 0 = (50+2)/1.05 = 49.52

MBA 2006 DDM |4|4 Dividend Discount Model (DDM): 1-year horizon 1-year valuation formula Back to example. Assume r = 10% Expected price r = expected return on shareholders'equity = Risk-free interest rate + risk premium Dividend yield = 2/47.27 = 4.23% Rate of capital gain = (50 – 47.27)/47.27 = 5.77%

MBA 2006 DDM |5|5 DDM: where does the expected stock price come from? Expected price at forecasting horizon depends on expected dividends and expected prices beyond forecasting horizon To find P 2, use 1-year valuation formula again: Current price can be expressed as: General formula:

MBA 2006 DDM |6|6 DDM - general formula With infinite forecasting horizon: Forecasting dividends up to infinity is not an easy task. So, in practice, simplified versions of this general formula are used. One widely used formula is the Gordon Growth Model base on the assumption that dividends grow at a constant rate. DDM with constant growth g Note: g < r

MBA 2006 DDM |7|7 DDM with constant growth : example YearDividendDiscFacPrice Data Next dividend: 6.00 Div.growth rate: 4% Discount rate: 10% P 0 = 6/( )

MBA 2006 DDM |8|8 Differential growth Suppose that r = 10% You have the following data: P 3 = 3.02 / (0.10 – 0.05) = Year1234 to ∞ Dividend Growth rate20% 5%

MBA 2006 DDM |9|9 A formula for g Dividend are paid out of earnings: Dividend = Earnings × Payout ratio Payout ratios of dividend paying companies tend to be stable. Growth rate of dividend g = Growth rate of earnings Earnings increase because companies invest. Net investment = Retained earnings Growth rate of earnings is a function of: Retention ratio = 1 – Payout ratio Return on Retained Earnings g = (Return on Retained Earnings) × (Retention Ratio)

MBA 2006 DDM | 10 Example Data: Expected earnings per share year 1: EPS 1 = €10 Payout ratio : 60% Required rate of return r : 10% Return on Retained Earnings RORE: 15% Valuation: Expected dividend per share next year: div 1 = 10 × 60% = €6 Retention Ratio = 1 – 60% = 40% Growth rate of dividend g = (40%) × (15%) = 6% Current stock price: P 0 = €6 / (0.10 – 0.06) = €150

MBA 2006 DDM | 11 Return on Retained Earnings and Debt Net investment =  Total Asset For a levered firm:  Total Asset =  Stockholders’ equity +  Debt RORE is a function of: Return on net investment (RONI) Leverage (L =  D/  SE) RORE = RONI + [RONI – i (1-T C )]×L

MBA 2006 DDM | 12 Growth model: example

MBA 2006 DDM | 13 Valuing the company Assume discount rate r = 15% Step 1: calculate terminal value As Earnings = Dividend from year 4 on V 3 = /15% = 3,358 Step 2: discount expected dividends and terminal value

MBA 2006 DDM | 14 Valuing Growth Opportunities Consider the data: Expected earnings per share next year EPS 1 = €10 Required rate of return r = 10% Why is A more valuable than B or C? Why do B and C have same value in spite of different investment policies Cy ACy BCy C Payout ratio60% 100% Return on Retained Earnings15%10%- Next year’s dividend€6 €10 g6%4%0% Price per share P 0 €150€100

MBA 2006 DDM | 15 NPVGO Cy C is a “cash cow” company Earnings = Dividend (Payout = 1) No net investment Cy B does not create value Dividend 0 But: Return on Retained Earnings = Cost of capital NPV of net investment = 0 Cy A is a growth stock Return on Retained Earnings > Cost of capital Net investment creates value (NPV>0) Net Present Value of Growth Opportunities (NPVGO) NPVGO = P 0 – EPS 1 /r = 150 – 100 = 50

MBA 2006 DDM | 16 Source of NPVG0 ? Additional value if the firm retains earnings in order to fund new projects where PV(NPV t ) represent the present value at time 0 of the net present value (calculated at time t) of a future investment at time t In previous example: Year 1: EPS 1 = 10 div 1 = 6  Net investment = 4  EPS = 4 * 15% = 0.60 (a permanent increase) NPV 1 = /0.10 = +2 (in year 1) PV(NPV 1 ) = 2/1.10 = 1.82

MBA 2006 DDM | 17 NPVGO: details

MBA 2006 DDM | 18 What Do Price-Earnings Ratios mean? Definition: P/E = Stock price / Earnings per share Why do P/E vary across firms? As: P 0 = EPS/r + NPVGO  Three factors explain P/E ratios: Accounting methods: –Accounting conventions vary across countries The expected return on shareholders’equity –Risky companies should have low P/E Growth opportunities

MBA 2006 DDM | 19 Beyond DDM: The Free Cash Flow Model Consider an all equity firm. If the company: –Does not use external financing (not stock issue, # shares constant) –Does not accumulate cash (no change in cash) Then, from the cash flow statement: »Free cash flow = Dividend »CF from operation – Investment = Dividend –Company financially constrained by CF from operation If external financing is a possibility: »Free cash flow = Dividend – Stock Issue Market value of company = PV(Free Cash Flows)
