Calculating Cost of Equity. Bohannon Corporation's common stock has a beta of 1.10. If the risk-free rate is 4.5% and the expected return on the market is 12%, what is the company's cost of equity capital?

R = Rf + (Rm - Rf)*B

= 4.5% + (12% - 4.5%)*1.10
= 4.5% + 7.5%*1.1
= 4.5% + 8.25%
= 12.75%

Cost of equity = 12.75%

To calculate the cost of equity, we can use the Capital Asset Pricing Model (CAPM) formula:

Cost of Equity = Risk-Free Rate + Beta * (Expected Return on the Market - Risk-Free Rate)

Let's plug in the given values:

Risk-Free Rate = 4.5%
Beta = 1.10
Expected Return on the Market = 12%

Using the CAPM formula, we can calculate:

Cost of Equity = 4.5% + 1.10 * (12% - 4.5%)

First, we calculate the difference between the expected return on the market and the risk-free rate:

12% - 4.5% = 7.5%

Next, multiply this difference by the beta:

1.10 * 7.5% = 8.25%

Finally, add the risk-free rate to the result:

4.5% + 8.25% = 12.75%

Therefore, the company's cost of equity capital is 12.75%.
