DFB will retain $2.00 per share of its earnings to reinvest in new projects that have an expected return of 15.0%% per year. Suppose DFB will maintain the same dividend payout rate, retention rate, and return on new investments in the future and will not change its number of outstanding shares. Assume next dividend is due in one year. a. What growth rate of earnings would you forecast for DFB? b. If OFB's equity cost of capital is 12.0%, what price would you estimate for DFB stock? c. Suppose Instead that DFB paid a dividend of $4.00 per share at the end of this year and retained only $1.00 per share in earnings. That is, it chose to pay a higher dividend instead of reinvesting in as many new projects. If DFB maintains this higher payout rate in the future, what stock price would you estimate for the firm now? Should DFB raise its dividend? a. What growth rate of earnings would you forecast for DFB? DFB's growth rate of eamings is |%. (Round to one decimal place.) b. If DFB's equity cost of capital is 12.0%, what price would you estimate for DFB stock? If OFB's equity cost of capital is 12.0%, then DFB's stock price will be $. (Round to the nearest cent) c. Suppose instead that DFB paid a dividend of $4.00 per share at the end of this year and retained only $1.00 per share in earnings. That is, it chose to pay a higher dividend instead of reinvesting in as many new projects. If DFB maintains this higher payout rate in the future, what stock price would you estimate for the firm now? If DFB paid a dividend of $4.00 per share next year and retained only $1.00 per share in earnings, then OFB's stock price would be $ . (Round to the nearest cent.) Should DFB raise its dividend? (Select the best choice below.) O A. Yes, DFB should raise dividends because, according to the dividend-discount model, doing so will always improve the share price. Q B. No. DFB should not raise dividends because the projects are positive NPV. O C. Yes, DFB should raise dividends because the return on now investments is lower than the cost of capital. D. No, DFB should not raise dividends because companies should always reinvest as much as possible, Click to select your answer(s).Q4. Use the semiannually compounded yield curve in the following table to price some xed income securities: Maturity T Yield r2 (0, T) 0-50 (a) 1.5year zero coupon bond (b) 2-year coupon bond paying 15% semiannually (d) 15year coupon bond paying 9% annually (e) 2-year oating rate bond with zero spread and semiannual payments (1") 15-year oating rate bond with zero spread and annual payments. For this question, assume r1 (0.5,0.5) = 6%. (h) 1.5-year oating rate bond with 40 basis point spread with annual payments. For this question, assume T1 (0.5, 0.5) = 6%.

Which assumption about consumer preferences does by three different consumers (Augn, Barbara, and each of the following individuals violate? Camina), holding everything else constant: . Adam likes basketball more than football; Auon Football more than baseball; and baseball more Barbara Camira than basketball. b. Christina prefers prune juice to orange juice but 02 cannot decide how she feels about grapefruit juice. C. Blake likes superhero comic books but prefers 5 comic books to 10 comic books. 54 2. By assumption, individual preferences must be tran- sitive so that if A is preferred to B, and B is preferred to C. then A is preferred to C.
