I don't have a definitive answer to that, but if you ask what the simplest way to do that is, contribution programs are always easy to put together—or easier. That's not to say that it is easy, but it is something that we know better. We know the mechanisms, and we know how to put things in a way that will work and be efficient. We have accountability tools that would come with that.
I'm not saying this is the only mechanism, or the only way to do that, but this is a way that we know, and we know it works.
