A$-$Rod Manufacturing Company is trying to calculate its cost of capital for use in making a capital budgeting decision. Mr$.$ Jeter, the vice president of finance, has given you the following information and has asked you to compute the weighted average cost of capital.

The company currently has outstanding a bond with a $10\mathrm{.}6$ percent coupon rate and another bond with an $8\mathrm{.}2$ percent rate. The firm has been informed by its investment banker that bonds of equal risk and credit rating are now selling to yield $11\mathrm{.}5$ percent. The common stock has a price of $$65$ and an expected dividend $($D$1)$ of $$1\mathrm{.}50$ per share. The historical growth pattern $($g$)$ for dividends is as follows:

$$1\mathrm{.}40$

$$1\mathrm{.}54$

$$1\mathrm{.}69$

$$1\mathrm{.}85$

Compute the historical growth rate, round it to the nearest whole number, and use it for g$.$

The preferred stock sells at $$85$ per share and pays a dividend of $$8\mathrm{.}50$ per share. The corporate tax rate is $25$ percent. The flotation cost is $2\mathrm{.}6$ percent of the selling price for preferred stock. The optimum capital structure for the firm is $35$ percent debt, $5$ percent preferred stock, and $60$ percent common equity in the form of retained earnings.

Compute the cost of capital for the individual components in the capital structure, and then calculate the weighted average cost of capital
