Answer:
Before tax cost of debt=3.72%
After-tax cost of debt =2.87 %
Explanation:
The yield to maturity to Maturity van be worked out using the formula below:
YM =( C + F-P/n) ÷ ( 1/2× (F+P))
C- annual coupon,
F- face value ,
P- current price,
n- number of years to maturity
YM - Yield to maturity
DATA
C- 4%× 100 = 4, P- 105, F- 100
AYM = 4 + (100-105)/27 ÷ 1/2× (100+105)
=0.0372 × 100= 3.72%
Yield to maturity =3.72%
Before tax cost of debt = Yield to maturity
Before tax cost of debt=3.72%
After tax cost of debt =Before tax cost of debt × (1-T)
Before tax cost of debt = 3.72%
Tax rate = 23%
After-tax cost of debt = 3.72%× (1-0.23) =2.87 %
After-tax cost of debt =2.87 %
