Answer:
7.45%
Explanation:
Total amount the firm received from bond issuance = $5,250,000 * 94%
= $4,935,000
The total coupon must be paid to bond holder annually
= Par value of $5,250,000 * coupon rate of 10%
= $5,250,000 * 10%
= $525,000
Rate of coupon paid over loan received = $525,000/ $4,935,000 = 10.64%
After-tax cost of this debt = 10.64%*(1-30%) = 7.45%
