At the end of this exam, I have attached the most recent 3 years of financial statements for caterpillar Tractor, Inc. (CAT). Your mission is to use this data an the following market data to determine CAT's before tax WACC. Google Finance reports CAT's beta to be equal to 1.599 Assume a market risk premium of 8% and the relevant risk free rate for CAPM to be 3.75% The average interest rate on CAT's current debt is 3.08% The average interest rate on CAT"s non-current debt is 5.56% Assume all level 1, 2 and 3 financial assets and liabilities are appropriately marked to market (fair value) compute WACC (before tax) for CAT
