My mental math may be slightly off, but then again the revenue and expenditures leave out the operating costs in each year, which run around $1.8 billion on average, so cumulatively for 2009 and 2010, off the top of my head, I'm not 100% sure, but it's around $11 billion, and in the Parliamentary Budget Officer's report he similarly showed that the cumulative balance reaches break-even by about 2014.
