Explanation / Answer

The WACC formula states that:

WACC = kd * wd * (1 - t) + kp * wp + ke * we

Where:

kd = cost of debt=8.9%

wd = % debt =31%

t = tax rate=30%

kp = cost of preferred stock =7.2%

wp = % preferred stock =7%

ke = cost of common equity =14.2%

we = % common equity=62%


So WACC = 8.9%*31%*(1-30%) + 7.2%*7% + 14.2%*62% = 11.24%


And ATax cost of debt = 8.9%*(1-30%)=6.23%
