Very briefly, Mr. Chairman, as is noted on page 2.37, I think, in part, this is a result of the move toward accrual accounting--when the government adopted accrual accounting. Accrual accounting for tax revenue poses some particular challenges. Some of the sub-systems we've referred to here were never designed to work in a world of accrual accounting. This is what's causing the differences between the general ledger, which is working on an accrual accounting basis, and the sub-system, which was never designed to do that. That's causing some of the difficulty here.
