Final answer:
The required rate of return for the riskier project by Piedmont Hotels, factoring in its beta, market risk premium, risk-free rate, and additional risk adjustment, should be set at 12.638%.
Step-by-step explanation:
The firm should set the required rate of return for the riskier project by first calculating the expected rate of return using the Capital Asset Pricing Model (CAPM) and then adjusting it for additional risk. Using the CAPM, the formula is as follows: Required Return = Risk-Free Rate + (Beta × Market Risk Premium). Since Piedmont Hotels is an all-equity company with a stock beta of 0.87, the market risk premium is 7.4 percent, and the risk-free rate is 4.0 percent, the initial expected rate of return would be:
Required Return = 4.0% + (0.87 × 7.4%) = 4.0% + 6.438% = 10.438%.
However, since the company considers the project riskier than its current operations, we add the adjustment of 2.2 percent to the project's discount rate:
Adjusted Required Return = Initial Required Return + Risk Adjustment = 10.438% + 2.2% = 12.638%.
Therefore, the adjusted required rate of return for the project would be 12.638%.
