Firm A: ROEA 0.00% 5% 10% 15% 20%

Firm B: ROEB -2% 5% 12% 19% 26%

Firm C: ROEC -5% 5% 15% 25% 35%

a. Calculate the expected value and standard deviation for Firm C’s ROE. ROEA = 10.0%, A 5.5%; ROEB 12.0%, B 7.7%.

b. Discuss the relative riskiness of the three firms’ returns. (Assume that these distributions are expected to remain constant over time.)

"c. Now suppose all three firms have the same standard deviation of basic earning

power (EBIT/Total assets), A B C 5.5%. What can we tell about

the financial risk of each firm?"
