Final answer:
The cost of common equity for Alderaan Incorporated is 5.64%.
Step-by-step explanation:
To calculate the cost of common equity for a company, you can use the dividend discount model (DDM) formula. The DDM formula is: Cost of Common Equity = Dividend / Current Stock Price + Growth Rate. In this case, the dividend is $2.84, the current stock price is $78.13, and the growth rate is 2%. Plugging in these values, we get: Cost of Common Equity = 2.84 / 78.13 + 0.02 = 0.0364 + 0.02 = 0.0564.
To convert the result to a percentage, we multiply by 100: Cost of Common Equity = 0.0564 * 100 = 5.64%. Therefore, the firm's cost of common equity is 5.64%.
