I'd just like to make the point that even if the government ever did move to accrual appropriations, that doesn't mean there would be no attention paid to cash any more. Cash is, of course, important, and you obviously have to control levels of debt and all the rest of it. But we can make an analogy with the private sector. The private sector works on accrual accounting and accrual budgets, but the cashflow statement is critical.
