QUESTION
A company is considering two mutually exclusive expansion plans. Plan A requires a $40 million expenditure on a large-scale integrated plant that would provide expected cash flows of$6.4 million per year for 20 years. Plan B requires a $12 million expenditure to build a somewhat less efficient, more labor-intensive plant with expected cash flows of$2.72 million per year for 20 years. The firm’s WACC is 10%. a. Calculate each project’s NPV and IRR. b. Graph the NPV profiles for Plan A and Plan B and approximate the crossover rate. c. Calculate the crossover rate where the two projects’ NPVs are equal. d. Why is NPV better than IRR for making capital budgeting decisions that add to shareholder value?
QUESTION
Brooks Sporting Inc. is prepared to report the following 2016 income statement (shown in thousands of dollars). $$ \begin{matrix} \text{Sales} & \text{\$ 15.300}\\ \text{Operating costs including depreciation} & \text{12.240}\\ \text{EBIT} & \text{\$ 30.60}\\ \text{Interest} & \text{330}\\ \text{EBT} & \text{\$ 2.730}\\ \text{Taxes (40\\%)} & \text{1.092}\\ \text{Net income} & \text{\$ 1.638}\\ \end{matrix} $$ Prior to reporting this income statement, the company wants to determine its annual dividend. The company has 320,000 shares of common stock outstanding, and its stock trades at $37 per share. a. The company had a 25% dividend payout ratio in 2015. If Brooks wants to maintain this payout ratio in 2016, what will be its per-share dividend in 2016? b. If the company maintains this 25% payout ratio, what will be the current dividend yield on the company’s stock? c. The company reported net income of$1.35 million in 2015.Assume that the number of shares outstanding has remained constant.What was the company’s per-share dividend in 2015? d. As an alternative to maintaining the same dividend payout ratio, Brooks is considering maintaining the same per-share dividend in 2016 that it paid in 2015. If it chooses this policy, what will be the company’s dividend payout ratio in 2016? e. Assume that the company is interested in dramatically expanding its operations and that this expansion will require significant amounts of capital. The company would like to avoid transactions costs involved in issuing new equity. Given this scenario, would it make more sense for the company to maintain a constant dividend payout ratio or to maintain the same per-share dividend? Explain.
