That has at least 3.
The first is that an alternate way of giving money back to shareholders - and one that many shareholders prefer for tax reasons - is through stock buybacks. Those are not counted in your plan.
The second I see is that you make it too easy for the company to manipulate its behaviour to affect how it treats employments. For instance a CEO with large guaranteed bonuses has an incentive to liquidate the company and sell it back to shareholders. (Taking, of course, a large guaranteed bonus for doing this.) Conversely a company can choose to not compensate shareholders in any way for a long period (shareholders continue to buy on future prospects - after all the company appreciates in value and someday management will change) to avoid handing out bonuses that the rank and file (emphasis on rank in the case of some programmers) expected.
And a third is that the company is just creating another way to compensate people without accounting for it in the present. Any such mechanism, widely used, leads to the exact problem that we see today with options. Namely that companies have large and real liabilities which the market has not factored in properly.

PS I strongly disagree with Fortune that options have been factored in. Ever seen a Bloomberg terminal? The easiest figures to get to, like P/E, do not factor in stock options, and so I can guarantee that traders while trading don't take them into account. If it was being factored in properly, then there wouldn't be any reason for companies to push to not report them...
PPS This is one of several items where people who have bought hogwash about "efficient markets" figure that information must have been factored in, missing the fact that creating a transaction cost for getting information can create real market distortions.
