Reuben Rios · Answer 1

0.7%

Explanation:

Because the company this bond at par value so the yield-to-maturity (used as proxy for pre-tax cost debt) is equal to the coupon rate of 7%. The weighted average cost of capitals (WACC) is stated as below:

WACC = Weight of equity x Cost of equity + Weight of debt x Pre tax cost of debt x (1 - Tax rate%)

So, when the tax rate decrease from 40% to 30%, component cost of debt in WACC will change by (40% - 30%) x 7% = 0.7%
