I'm glad you asked that question because I was scratching my head on that one, too, but the answer is pretty obvious, once I think about it.
The CRA has a provision in the act to carry forward.... Basically, our appropriations cover a two-year period instead of a one-year period. So unused amounts from one year carry forward. The amount in question, the $167.724 million--that was my computation—is basically the unused portion of our 2006-07 appropriations that now become available in 2007-08.
