Fama’s Llamas has a WACC of 9.7 percent. The company’s cost of equity is 12 percent, and its pretax cost of debt is 7.5 percent.

Bezzdna [24]

Answer:

0.4766

Explanation:

Given:

WACC = 9.7%

Company’s cost of equity = 12%

Pretax cost of debt = 7.5%

Tax rate = 35%

Now,

WACC

= Weight × Cost of equity + (1 - weight) × Pretax cost of debt × (1-tax rate)

0.097 = weight × 0.12 + ( 1 - weight ) × 0.075 × (1 - 0.35)

0.097 = 0.12 × weight + 0.04875 - 0.04875 × weight

0.04825 = 0.07125 × weight

weight = 0.6772

also,

weight = $\frac{\textup{Equity}}{\textup{Debt + Equity}}$

$\frac{\textup{1}}{\textup{weight}}$ = $\frac{\textup{Debt+equity}}{\textup{Equity}}$

$\frac{1}{0.6772}$ = $\frac{\textup{Debt}}{\textup{Equity}}$ + 1

1.4766 = $\frac{\textup{Debt}}{\textup{Equity}}$ + 1

$\frac{\textup{Debt}}{\textup{Equity}}$ = 0.4766
