Problem
Use SNA company on this website (yahoo finance). you have to use the following equation twice: WACC = Wd*Rd*(1-t)+We*Re, You need to calculate WACC one time using the book value weights and another time using market value weights. Rd, Re, and t (21%) are the same in both of them. Remember, the book value of debt is assumed to be the same as the market value of debt, however, the book value of equity from the balance is not the same as the market value of equity which is the market capitalization. Remember, yahoo finance is giving you the numbers in thousands.
