Factors that affect the WACC equation Each of the following factors affects the weighted average cost of capital (WACC) equation. Which of the following factors are outside a firm's control? Check all that apply. Tax rate The firm's dividend payout ratio The inflation rate The impact of a firm's cost of capital on managerial decisions Consider the following case: National Petroleum Refiners Corporation (NPR) has two divisions, L and H. Division L is the company's low-risk division and would have a weighted average cost of capital of 8% if it was operated as an independent company. Division H is the company's high-risk division and would have a weighted average cost of capital of 14% if it was operated as an independent company. Because the two divisions are the same size, the company has a composite weighted average cost of capital of 11%. Division L is considering a project with an expected return of 9.5%. Should l Petroleum Refiners Corporation (NPR) accept or reject the project? National Accept the project Reject the project On what grounds do you base your accept-reject decision? Division L's project should be accepted, since its re n is greater than the risk-based cost of capital for the division Division L's project should be accepted, because its return is less than the risk-based cost of capital for the division
