I think the problem is twofold. One is that we have very difficult data to try to do any kind of analysis with. If you look at the charity tax returns, you'll see that the charity tax returns are not specifically asked how much money they received from corporations or businesses.
But from a corporation standpoint, corporations give money and corporations give food, but corporations also give sponsorships, and how they're treated under the tax code is going to differ. So trying to get a number on their involvement is going to be very difficult. I suspect their involvement is probably more than what was just stated as $2 billion, but what that number is, I don't know. I think it would be difficult for any of us to know.
