I was digging around the Net to understand better the issue of expensing of employee stock options for companies.
Initially I had the mistaken idea that companies previously could choose to "capitalize" or expense the option grants, and was wondering how exactly do you "capitalize" an option grant, later I found out that you can't: the old alternative to expensing them is to disclose them in footnotes =)
Another point that I was trying to clarify was whether there is a tax rebate if the tax benefit from stock options is greater than the net income. Turns out that there isn't a rebate, so the actual tax benefit ($cash) shown in the cash flow statement might be less than the calculated benefit using the tax rate.
