funding cliff
n.— «Naturally, however, there’s a budget sleight-of-hand. Known as a “funding cliff,” the yearly Schip layout increases to $13.9 billion in 2011, then abruptly cuts spending by 65% below current funding levels. This helps “score” the bill as costing only $35 billion over the five-year budget window, but it also means that come 2012 Congress will either have to pass new spending or kick kids off the rolls. » —“Schip for Everyone” Wall Street Journal Sept. 28, 2007.
