A firm has $3 mn in outstanding bonds, with an 8% fixed rate (assume annual payments). The bonds trade at $92 per $100 par. The firm’s marginal tax rate is 35%. What is the aftertax component cost of debt to be used in calculating WACC?
ANSWER
If the bonds are trading at $92 per $100 par, the required yield is 9.26%, and the market value of the issue is $2.76 million.
The equivalent aftertax cost of this financing is: 9.26% (1 – 0.35) = 6.02%.
I don’t get get it. How do they get to 9.26%? and then $2.76million ?
HELP PLEASE!
