Answer:
The accept/reject decision depends on the firm's risk-adjustment policy. If Weatherall's policy is to increase the required return on a riskier-than-average project to 3% over rS, then it should reject the project - option C
Explanation:
Once the said project is riskier, the accept/ reject criterion will be considered based on risk adjusted discount rate which would be higher than company’s cost of capital by the amount of risk premium. Here the risk premium is 3%.
Thus, the decision to accept/reject depends on the risk-adjustment policy of the firm. If Weatherall's policy is to increase the required return on a riskier-than-average project to 3% over rS, then it should reject the project - option C is the best answer.
