Answer:
Corporate Bond:
After tax return of a 11.23 percent, 20 year, a-rated corporate bond in the 15 percent marginal tax bracket
= Before tax rate of return * (1 - Tax rate)
= 11.23% * (1 - 15%)
= 9.55%
Hence:
The after-tax return of a 11.23 percent, 20 year, a -rated corporate bond for an investor in the 15 percent marginal tax bracket is 9.55 %
Tax exempt municipal bond
After tax return of 7.09 percent, 20 year, a-rated, tax exempt municipal bond = 7.09%
Comparison:
Corporate bond is better.
Yield of corporate bond is 9.55% which is higher than yield of tax exempt municipal bond which is 7.09%
When marginal tax bracket = 33%
After tax return of a 11.23 percent, 20 year, a-rated corporate bond = 11.23% * (1 - 33%) = 7.52%
Even when marginal tax rate is 33%, corporate bond is better. In this case yield of corporate bond is 7.52% which is higher than yield of tax exempt municipal bond which is 7.09%
