While calculating diluted EPS, in case of convertible bonds, we add back the interest (net of tax) to the numerator in the EPS formula.
My doubt is - is it the interest net of tax or the tax amount itself that should be added?
For eg.
Interest on convertible bonds - $60,000
Marginal Tax rate 40%
Should I add to the numerator : $24000 ($60,000*0.4) or $36000 ($60,000*0.6). In case it is $24000, please add one or two lines to explain the reasoning, because I am under the impression that it should be $36000.
