Construct a spreadsheet to estimate the optimal capital structure for a hypothetical company. The attached spreadsheet contains all the information you will need. However, to work out the solution, you will need to complete the spreadsheet by entering appropriate formulas. Note that in most instances, proper linking will mean that you only need to enter the appropriate formula once and then can copy it to other relevant cells in a particular column.

Note that you are given the pre-tax cost of debt at different levels of financial leverage, but must calculate the after-tax cost of debt. Also, you will need to estimate the beta at various levels of financial leverage using the Hamada Model. From there you will need to use the CAPM to calculate the cost of equity at each level of financial leverage. Once you have done that, the value of the firm is just the discounted present value of the expected Free Cash Flows cash flow at the implied WACC. Note that we are assuming no growth in the FCFs, so the discounting is done with the regular perpetuity model.
