Boing is organised into three different divisions: the commerical airplanes division, the defense division, and the global services division. You are trying to estimate the cost of capital for the defense division. Boeings current debt to enterprise value ratio (net of excess cash) is 23% and Boeing uses the same amount of leverage across all three divisions. Assume that the cost of debt for the defense division is 3.1%. You further know that the 10 -year risk-free rate is 1.75%, and the market risk premium is 7%. You have collected the following data on three companies in the defense industry (see table below). What is the best estimate for the cost of equity for the defense division of Boeing? Select the best one. (hint: Use the average unlevered cost of capital of the defense companies to calculate the cost of equity for Boeing's defense division) Data on Defense Comnanies . 6.18% II. 9.10% III. 8.82%
