Answer:
sustainable growth rate = retention rate x ROE
ROE = 10%
a) growth rate:
if retention rate is 0%, growth rate = 0. Pâ‚€ = $4 / 10% = $40
if retention rate is 30%, growth rate = 3%. Pâ‚€ = $4.12 / 7% = $58.86
if retention rate is 50%, growth rate = 5%. Pâ‚€ = $4.20 / 5% = $84
b) growth rate if ROE increases to 15%
if retention rate is 0%, growth rate = 0. Pâ‚€ = $4 / 10% = $40
if retention rate is 30%, growth rate = 4.5%. Pâ‚€ = $4.20 / 5.5% = $76.36
if retention rate is 50%, growth rate = 7.5%. Pâ‚€ = $4.30 / 2.5% = $172
c) What is the present value of growth opportunities (PVGO) for each reinvestment rate?
PVGO = stock price - value of no growth
value of no growth = $40
when g = 0%, then PVGO = $40 - $40 = $0
when g = 3%, then PVGO = $58.86 - $40 = $18.86
when g = 5%, then PVGO = $84 - $40 = $44
when g = 4.5%, then PVGO = $76.36 - $40 = $36.36
when g = 7.5%, then PVGO = $172 - $40 = $132
