3. Ellington Electronics wants you to calculate its cost of common stock. During the next 12 months, the company expects to pay dividends (D₁) of $1.50 per share, and the current price of its common stock is $30 per share. The expected growth rate is 8 percent. (Do not round intermediate calculations. Round the final answer to 2 decimal places.)

a. Compute the cost of retained earnings (K_e).

Cost of retained earnings %

b. If a $2 flotation cost is involved, compute the cost of new common stock (K_n).

Cost of new common stock %

4. The Tyler Oil Companys capital structure is as follows:

Debt	35	%
Preferred stock	15
Common equity	50

The aftertax cost of debt is 7 percent; the cost of preferred stock is 10 percent; and the cost of common equity (in the form of retained earnings) is 13 percent.

a-1. Calculate Tyler Oil Companys weighted average cost of capital. (Round the final answers to 2 decimal places.)

	Weighted Cost
Debt (Kd)	%
Preferred stock (Kp)
Common equity (Ke)
Weighted average cost of capital (Ka)	%

As an alternative to the capital structure shown above for Tyler Oil Company, an outside consultant has suggested the following modifications.

Debt	60	%
Preferred stock	5
Common equity	35

Under this new and more debt-oriented arrangement, the aftertax cost of debt is 8.8 percent, the cost of preferred stock is 10.5 percent, and the cost of common equity (in the form of retained earnings) is 15.5 percent.

5. Eaton Electronic Companys treasurer uses both the capital asset pricing model and the dividend valuation model to compute the cost of common equity (also referred to as the required rate of return for common equity).

Assume the following:

Rf	=		7	%
Rm	=		10	%
j	=		1.6
D1	=	$	0.70
P0	=	$	19
g	=		8	%

a. Compute K_j (required rate of return on common equity based on the capital asset pricing model). (Do not round intermediate calculations. Input your answer as a percent rounded to 2 decimal places.)

K_j %

b. Compute K_e (required rate of return on common equity based on the dividend valuation model). (Do not round intermediate calculations. Input your answer as a percent rounded to 2 decimal places.)

K_e %
