Very briefly; it's relatively easy. Mr. Hsu's question is a very sharp and pointed and important one. It's very important to recognize the difference in what I'll call the instrumental objective in raising more funds for the non-profit sector through a change in tax credits. But charitable giving has another dimension to it that involves civic participation: how people learn to contribute to their communities. That's where increasing the number of donors and the activity of giving become very important as long-term objectives.
We don't know very much about that.
