Problem 9.31 Nonconstant Growth Riker Departmental Stores management has forecasted a growth rate of 40 percent for the next two years, followed by growth rates of 25 percent and 20 percent for the following two years. It then expects growth to stabilize at a constant rate of 7.5 percent forever. The firm paid a dividend of $3.50 recently. If the required rate of return is 18 percent, what is the current value of Riker's stock? Hint: Calculate the expected dividends for years 1 through 5 using the appropriate growth rates. Next, compute the present value of the dividends in years 1 through 4. Use the expected dividend in year 5 to calculate P4, find the present value of P4, and add this result to the present value of the dividends in years 1 through 4. D0 = g1 = g2 = g3 = g4 = Constant Growth Rate (g) = Required Rate of Return (R) = D1 = D2 = D3 = D4 = D5 = PV_D1 = PV_D2 = PV_D3 = PV_D4 = PV of Dividends (years 1-4): P4 = PV_P4 = Current Price of the Stock (P0) = Problem 9.34 Constant Growth Perry, Inc., declared a dividend of $2.50 yesterday. You are interested in investing in this company, which has forecasted a constant growth rate of 7 percent for its dividends, forever. The required rate of return is 18 percent. a. Compute the expected dividends D1, D2, D3, and D4. D0 = Constant Growth Rate (g) = Required Rate of Return (R) = D1 = D2 = D3 = D4 = b. Compute the present value of these four dividends. PV_D1 = PV_D2 = PV_D3 = PV_D4 = PV of Dividends (years 1-4): c. What is the expected value of the stock four years from now (P4)? Hint: Compute the expected dividend in year 5 (D5) and then use the constant growth equation to calculate P4. D5 = P4 = d. What is the value of the stock today based on the answers to parts b and c. PV_P4 = Price of the stock today: e. Use the equation for constant growth (Equation 9.4) to compute the value of the stock today. Price of the stock today: Problem 9.35 Supernormal Growth Zweite Pharma is a fast growing drug company. Management forecasts that in the next 3 years, the company's dividend growth rates will be 30 percent, 28 percent, and 24 percent respectively. Last week it paid a dividend of $1.67. After 3 years, management expects dividend growth to stabilize at a rate of 8 percent. The required rate of return is 14 percent. a. Compute the dividends for each of the next 3 years, and calculate their present value. D0 = g1 = g2 = g3 = Required Rate of Return (R) = D1 = D2 = D3 = PV_D1 = PV_D2 = PV_D3 = PV of Dividends (years 1-3): b. Calculate the price of the stock at the end of year 3, when the firm settles to a constant growth rate. Hint: Calculate D4 (expected dividend in year 4) and use the constant growth dividend model to estimate P 3. Constant Growth Rate (g) = D4 = P3 = c. What is the current price of the stock? Hint: Find the present value of P3 and add this amount to the present value of the first three years of dividends. PV_P3 = Current Price of the Stock (P0) =
