Answer:
a) 12.20%
Step-by-step explanation:
For calculating the WACC which is termed as weighted average cost of capital, will be calculated here by taking out weighted proportion of each bonds, preferred stock and new common stock and multiplying these weighted proportion by the cost of debt, cost of preferred stock and cost of new common equity respectively. And at last we will add all three of them.
WACC = weightage of debt x cost of debt
+
weightage of preferred stock x cost of preferred stock
+
weightage of common stock x cost of common stock
= 25% ( 5/20 x 100) x 5% + 15% x 9% + 60% x 16%
= .25 x .05 + .15 x .09 + .6 x .16
= .0125 + .0135 + .096
= .122 ( multiplying by 100 to make it in percentage)
= 12.2%
