Answer:
a.9.500%
b.8.658%
Step-by-step explanation:
The formula for computing tax equivalent yield is tax-free bond yield divided by the tax rate reciprocal.
Tax equivalent yield=tax free municipal bond yield rate/tax reciprocal
The tax reciprocal is 1-tax rate
for tax free municipal bond yield of 6.84% and the tax rate of 28%,the tax equivalent yield is computed thus:
tax equivalent yield=6.84%/(1-0.28)
=6.84%/0.72
=9.500%
At marginal tax rate of 21%,tax equivalent yield is computed thus:
Tax equivalent yield=6.84%/(1-0.21)
=6.84%/0.79
=8.658%
