Answer:
a)
Div₁ = $3
Div₂ = $5
Div₃ = $7.50
Div₄ = $10
Div₅ = $2.50
the terminal value at year 4 = $2.50 / 15% = $16.67
P₀ = $3/1.15 + $5/1.15² + $7.50/1.15³ + $26.67/1.15⁴ = $2.61 + $3.78 + $4.93 + $15.25 = $26.57
dividend yield over the first year = $3 / $26.57 = 11.29%
b)
P₁ = $5/1.15 + $7.50/1.15² + $26.67/1.15³ = $4.35 + $5.67 + $17.47 = $27.49
capital gains yield = ($27.49 - $26.57) / $26.57 = 3.46%
