The Chippewa Co. has an equity cost of capital of 18% %. The weight of debt is .5, the tax rate is 40%, and the cost of debt is 15%. Chippewa is considering using the FTE method to value a project (this method entails calculating the value of the project without the financing side effects, and then adding back the value of financing side effects one by one). What is the discount rate that they would use in their analysis to find the value of the project?
