Answer:
Debt
7.65%
6.53%
Step-by-step explanation:
The debt finance has its capital component adjusted for tax when computing weighted average cost of capital.
The after tax cost of borrowing =pretax cost of debt*(1-t)
t is the tax rate of 25% or 0.25
The after tax cost of borrowing =10.20%*(1-0.25)=7.65%
The pretax cost of bond=rate(nper,pmt,-pv,fv)
nper is the duration of bond which is 5 years
pmt is the annual interest=$1000*10%=$100
pv is the current price of $1,050.76
fv is the face value of $1000
=rate(5,100,-1050.76,1000)=8.70%
After tax cost of bond=8.70% *(1-0.25)=6.53%
