Q4. Carol Enterprises is considering a major expansion program that has been proposed by the company's information technology group.

The current price of the firm's 10%, $30 par value, quarterly dividend, perpetual preferred stock is $33.33. Carol's common stock is currently selling for $45.00 per share. Its last dividend was $3.81, and dividends are expected to grow at a constant rate of 4% in the foreseeable future. Carol's beta is 1.44, the yield on T-bonds is 6%, and the market risk premium is estimated to be 5%. For the bond-yield- plus-risk premium approach, the firm uses a risk premium of 3%. The value of Carol's current bonds is $3,000,000, it has 30,003 preferred shares outstanding, and the total number of common shares trading in the market are 133,333. a.
