Answer:
a. Weighted average flotation cost
= FCE(E/V) + FCD(D/V)
= 7(100/170) + 4(70/170)
= 4.12 + 1.65
= 5.77%
V = E + D
V = 100 + 70 = 170
b. Flotation cost of debt financing
= 4% x $18 million
= $0.72 million
True cost of the building after taking flotation cost into account
= $18 million + $0.72
= $18.72
Explanation:
The weighted average flotation cost is the flotation cost of equity multiplied by the proportion of equity in the capital structure plus flotation cost of debt multiplied by proportion of debt in the capital structure. The total market value is 100 + 70 = 170. Since the debt-equity ratio is 0.7. Debt takes 70 while equity takes 100. The proportion of equity in the capital structure is 100/170 while the proportion of debt in the capital structure is 70/170.
