Answer:
The equivalent tax-free yield is:
10.42%
Explanation:
Tax-free yield = 7.5%/(1 - 28%)
= 10.42%
This equivalent tax-free yield is the yield of the 7%, 15-year corporate bond that will make it comparable to a municipal bond that is tax-free. To calculate the tax-free yield, we divide the yield rate by the inverse of the tax bracket. In this case, this yields 10.42%. This implies that for this corporate bond to be valued equally with a municipal tax-free bond, the yield must be at least 10.42%.
