corporate equivalent

corporate equivalent

The yield that would need to be realized on a taxable bond selling at par in order to achieve the same aftertax yield to maturity of a bond selling at a premium or discount. For example, a $1,000 par, 10% coupon bond that sells for $900 and is due to mature in five years would provide a yield to maturity of 12.8%. However, after taxes have been paid at a rate of 28% on the $100 gain ($1,000 - $900) and 28% on the $100 annual interest payments, the aftertax yield to maturity is slightly under 10%. The corporate equivalent yield is 0.1/(1 - 0.28), or 13.9%.
