# Optimal Capital Structure: Calculate the WACC

Company B has a optimal capital structure with the following sources/target market ratios:

SOURCE OF CAPITAL Target Market Ratios

long term debt 30%

preferred stock 5%

commonn stock equity 65%

Debt: The firm can sell a 15 year, $1,500 par value, 10 percent bond for $1,300

A flotation cost of 2% of the face value would be required in addition to the

discount of $200

Preferred Stock: The firm issues stock at $70 per share par value. The stock will

pay a $7.00 annual dividend. The cost of issuing and selling

the stock is $4 per share

Common Stock: Common Stock is currently selling for $40 per share. The

expected dividend to be paid at the end of the year is $4.56.

The dividend 5 years ago was $2.34 and has been growing at a

constant rate ever since. It is expected that to sell, a new

common stock issue must be underpriced at $1.10 per share

and the firm must pay $1.10 per share in flotation costs. The

firm has a marginal tax rate of 35%

The firm has used up all of it's retained earnings. Calculate the firm's weighted average cost of capital
