Answer:
Using the current capital structure
Ke = Rf + β(Risk premium)
Ke = 5 + 1.60(6)
Ke = 5 + 9.60
Ke = 14.60
Weighted cost of equity
= 14.60(20/100)
= 2.92%
Using the new debt-equity ratio
Ke = 5 + 1.60(6)
Ke = 5 + 9.6
Ke = 14.60%
Weighted cost of equity
Ke = 14.60(60/100)
Ke = 8.76%
Difference in cost of equity
= 2.92% - 8.76%
= -5.8%
Explanation:
There is need to calculate the cost of equity based on capital asset pricing model where Rf represents risk-free rate, Rp denotes risk-premium and β refers to beta. Then, we will calculate the weighted cost of equity by multiplying cost of equity by the proportion of equity in the capital structure. We will also calculate the new weighted cost of equity by multiplying the cost of equity the new proportion of equity in the capital structure. Finally, we will deduct the new weighted cost of equity from the old weighted cost of equity.
