Answer:
A) What is Avicorp's pre-tax cost of debt?
B) If Avicorp faces a 40% tax rate, what is its after-tax cost of debt?
Explanation:
in order to calculate the pretax cost of debt, I will use a $1,000 bond
coupon rate = 5.8% x $1,000 = $58 / 2 semiannual coupons = $29
current bond price $960
years to maturity = 5 x 2 coupons = 10 periods
you can use a financial calculator or an excel spreadsheet to calculate effective annual yield, but we can also calculate it using the yield tot maturity formula:
YTM = {coupon + [(face value - market value)/n]} / [(face value + market value)/2]
YTM = {29 + [(1,000 - 960)/10]} / [(1,000 + 960)/2] = 3.367% x 2 coupons per year = 6.73%
the after tax cost of debt = 6.73% x (1 - 40%) = 6.73% x 0.6 = 4.04%
