Calculation of individual costs and WACC

Dillon Labs has asked its financial manager to measure the cost of each specific type of capital as well as the weighted average cost of capital. The weighted average cost is to be measured by using the following weights: 35% long-term debt, 20% preferred stock, and 45% common stock equity (retained earnings, new common stock, or both). The firm's tax rate is 30%.

Debt The firm can sell for $975 a 13-year, $1,000-par-value bond paying annual interest at a 12.00% coupon rate. A flotation cost of 2% of the par value is required in addition to the discount of $25 per bond.

Preferred stock

9.00% (annual dividend) preferred stock having a par value of $100 can be sold for $85. An additional fee of $4 per share must be paid to the underwriters.

Common stock

The firm's common stock is currently selling for $60 per share. The dividend expected to be paid at the end of the coming year (2016) is $4.31. Its dividend payments, which have been approximately 70% of earnings per share in the past 5 years, were as shown in the following table:

Year	Dividend
2015	$4.01
2014	$3.73
2013	$3.47
2012	$3.23
2011	$3.00

It is expected that to attract buyers, new common stock must be underpriced $7 per share, and the firm must also pay $4.00 per share in flotation costs. Dividend payments are expected to continue at 70% of earnings. (Assume that r Subscript r_r r_s.)
