Answer: 4.2%
Explanation:
Bonds are debt instruments which means that the interest paid on bonds is tax deductible. After the tax is deducted, the after tax yield shows the actual yield being paid on the bond given the tax rate.
The after tax yield on a bond is calculated by the formula:
= Before tax yield * ( 1 - Tax rate)
= 7% * ( 1 - 40%)
= 4.2%
