EBIT为什么不用加D*T
Company M, a manufacturer of automobile, is in the 25% tbracket. The company is currently 37.5% bt-financean62.5% equity-finance with the market value of anEBIT of $1 million an$0.5 million, respectively. What`s the WAof Company M accorng to the MM`s proposition with tax? 11.25% 14.04% 18.73% B is correct. 考点CapitStructure Theory: with t解析根据公式 VL=VVE=EBIT∗(1−T)WACCV_L=V_V_E=\frac{EBIT\ast(1-T)}{WACC}VL=V+VE=WACCEBIT∗(1−T) V= $1 million, E = 0.6, 求得VE = $1.67 million 代入VL = 2.67 = 0.5∗(1−25%)WACC\frac{0.5\ast(1-25\%)}{WACC}WACC0.5∗(1−25%) ，求得WA= 14.04% .Vul这个公式和题目用的Vl这两个长得很像，有什么关系吗？
14.04% 18.73% B is correct. 考点CapitStructure Theory: with t解析根据公式 VL=VVE=EBIT∗(1−T)WACCV_L=V_V_E=\frac{EBIT\ast(1-T)}{WACC}VL=V+VE=WACCEBIT∗(1−T) V= $1 million, E = 0.6, 求得VE = $1.67 million 代入VL = 2.67 = 0.5∗(1−25%)WACC\frac{0.5\ast(1-25\%)}{WACC}WACC0.5∗(1−25%) ，求得WA= 14.04% 这题跟mm理论什么关系啊

14.04% 18.73% B is correct. 考点CapitStructure Theory: with t解析根据公式 VL=VVE=EBIT∗(1−T)WACCV_L=V_V_E=\frac{EBIT\ast(1-T)}{WACC}VL=V+VE=WACCEBIT∗(1−T) V= $1 million, E = 0.6, 求得VE = $1.67 million 代入VL = 2.67 = 0.5∗(1−25%)WACC\frac{0.5\ast(1-25\%)}{WACC}WACC0.5∗(1−25%) ，求得WA= 14.04% 老师，为什么VL的公式中没有？不考虑税盾吗？MM有税理论不是VL=VU+吗？
