Using the WACC in practice: Polys Parrot Shops has found that its cost of common equity capital is 17 percent. It has 7-year maturity bonds outstanding with a price of $767.03 that have a coupon rate of 7 percent. If the firm is financed with $120,000,000 of common shares (market value) and $80,000,000 of debt, then what is the after-tax weighted average cost of capital for Polys if it is subject to a 35 percent marginal tax rate? add calculations ex: how you derrived at the total. excel spread sheet form please. Thank you!
