Answer and Explanation:
The computation is shown below
a. For before tax cost of debt
But before that following calculations need to be determined
For Bond 1:
Face value = $33,000,000
Coupon payment = 0.05 × $33,000,000 = $1,650,000
The Price of the bond is
= Coupon × [ 1 - 1 ÷ ( 1 + r)^n] ÷ r + FV ÷ ( 1 + r)^n
= $1,650,000 × [ 1 - 1 ÷ ( 1 + 0.06)^10] ÷ 0.06 + $33,000,000 ÷ ( 1 + 0.06)^10
= 1,650,000 × 7.360087 + 18,427,027.64
= $30,571,171.196
For Bond 2:
Price = 0.9 × $38,000,000
= $34,200,000
Now
Coupon = 0.06 × $38,000,000
= $2,280,000
Now before tax cost of debt is
Given that
PV -$34,200,000,
FV $38,000,000,
N 15,
PMT $2,280,000
The formula is shown below:
= RATE(NPER,PMT, PV,FV,TYPE)
After applying the above formula, the Before tax cost of debt of bond is 7.1053%
Now
Total market value is
= $34,200,000 + $30,571,171.196
= $64,771,171.19
And,
finally
Before tax cost of debt for olympic is
= ($30,571,171.196 ÷ 64,771,171.19) × 0.06 + ($34,200,000 ÷ 64,771,171.19) × 0.071053
= 0.028319 + 0.037517
= 0.0658 or 6.58%
b)
And,
After tax cost of debt is
= 0.0658× ( 1 - 0.3)
= 0.0461 or 4.61%
