Answer:
Difference in WACC =0.72%
Explanation:
As per the data given in the question,
Calculation for the Weighted Average Cost of Capital (WACC):
WACC = Common equity × Equity cost + preferred stock × cost of preferred stock + (Debt × (cost of debt ( 1 - tax rate)))
= (36% × 14.7%) + (6% × 12.2%) + (58% × (11.10% ( 1 - 40%)))
= 0.098868
= 9.89%
If it is necessary to carry a new equity then,
WACC = (36% × 16.8%) + (6% × 12.2%) + (58% × (11.10% ( 1 - 40%)))
= 0.10608
= 10.61%
Difference = 10.61% - 9.89%
=0.72%
