Answer:
correct option is a. 8.79%
Step-by-step explanation:
given data
bonds mature N = 20 years
annual coupon = 8%
par value FV = $1,000
market price PV = $1,050
tax rate = 40%
risk-free rate = 4.50%
market risk premium = 5.50%
stock's beta = 1.20
target capital structure consists = 35%
solution
we gte here first Annual coupon payment
PMT = 8% × 1000 .................1
PMT = 80
we get here YTM of the bond (rD)
we can use financial calculator
here pretax cost of debt, rd
CPT I/Y = 7.51%
Now we get
cost of equity (rE) with help of CAPM
CAPM; r = risk free + beta (Market risk premium) .....................2
so
rE = 0.0450 + 1.20 × (0.0550)
rE = 0.0450 + 0.066
rE = 11.1 %
so we can get here WACC that is
WACC = wE × rE + wD × rD × (1-tax) ....................3
here rD is pretax cost of deb and w is weight
so
WACC = (0.65×0.111) + [0.35×0.0751×(1-0.40) ]
WACC = 0.0879
WACC = 8.79%
correct option is a. 8.79%
