Suppose that Caterpillar Incorporated is considering a new line of construction graders. To launch the new product, Caterpillar will have to invest $200.00 million. The target capital structure for Caterpillar is 45.00% debt and 55.00% equity (market values).

The CFO for the company believes that new debt can be issued with an 8.00% annual coupon rate. After reviewing the company's beta, the CFO also believes that common stockholders require a 15.00% return for the new investment.

The company projects an annual after-tax cash flow of $65.00 million for the new project. The company has a marginal tax rate of 35.00%, and expects to run the project for 10.00 years.

What is the weighted average cost of capital for the firm?
