Answer:
The estimated unlevered cost of equity is 12.30%.
Step-by-step explanation:
Debt-to-value ratio = 0.4
Equity-to-value ratio = 1 - Debt-to-value ratio = 1 - 0.4 = 0.6
The estimated unlevered cost of equity can be calculated solving the following formula:
Levered equity cost of capital = Unlevered cost of equity + ((Debt-to-value ratio / Equity-to-value ratio) * (100% - Tax rate) * (Unlevered cost of equity - Pretax cost of debt)) .............. (1)
Substituing all the relevant values into equation (1), we have:
14.92% = Unlevered cost of equity + ((0.4/0.6) * (1 - 23%) * (Unlevered cost of equity - 7.2%))
Let R0 = Unlevered cost of equity, we have:
14.92% = R) + ((0.4/0.6) * (1 - 23%) * (R0 - 7.2%))
14.92% = R0 + (0.666666666666667 * 0.77 * (R0 - 7.2%))
14.92% = R0 + (0.513333333333334 * (R0 -7.2%))
14.92% = R0 + (0.513333333333334 * R0) - (0.513333333333334 * 7.2%)
14.92% = R0 + (0.513333333333334 * R0) - 0.03696
14.92% + 0.03696 = R0(1 + 0.513333333333334)
0.18616 = R0(1.513333333333334)
R0 = 0.18616 / 1.513333333333334
R0 = 0.1230, or 12.30%
Therefore, the estimated unlevered cost of equity is 12.30%.
