You are estimating the weighted average cost of capital (WACC) for your company based on the following information:

Equity information	Debt information
50 million common shares outstanding	$1 billion of debt at face value
$80 market price per share	Debt quoted price = 110
Stock beta of 1.15	Coupon rate = 9%, semi-annual
Market risk premium of 9%	15 years to maturity
Risk-free rate of 5%	Marginal tax rate of 40%

Calculate the following returns: (1/100 of one percent without % sign, e.g. 12.671, if a negative percentage, -9.56).

1. Cost of equity (%):

2. Cost of debt (%):

3. Proportion of debt (%):

4. Proportion of equity (%):

5. Weighted average cost of capital (%):
