2. WACC = rd(D/V)(1-t)+re(E/V) According to Table 1: D/V=42.2%; Spread to treasury(Premium)=1.62% • According to Table 2: Because the majority of large firms and financial analysts report using long-term yields to determine the risk-free rate, so we choose the rate of treasury bonds with maturity of 30-Year (4.98%) as the risk-free rate, rf=4.98%. According to the material: Midland’s β=1.25, EMRP=5.0% Cost of Debt rd can be calculated by adding spread over US Treasury securities of a similar maturity. So rd=4.98%+1.62%=6.6% Cost of Equity re = rf + β*EMRP=4.98%+1.25*5.0%=11.23% E/V=1-D/V=57.8% Tax rate is not mentioned in material. But according to Mid land Balance Sheet:
