From what I understand, looking at FIRST's financials, which are publicly available, they have $8M in "cash assets." Not in scholarship funds, in cash reserve. It's definitely FIRST's money. Their increase in cash and cash equivalents from 2006 to 2007 was $1.4M, so it obviously doesn't have to do with bills to be paid. That seems a bit excessive for a not-for-profit corporation to me.
