Yes, the difference in spending was lower than expected in 2012-13. At the same time departments had been lapsing a bit more than $10 billion compared to their appropriations.
It's fairly difficult to explain from a forecasting point of view because the lapse we talk about in our forecasts between us at Finance is the actual lapse. The lapse that has been in the media up to now is a cash lapse. Departments access cash in a year that they could appropriate to spend, and if they don't spend that, they lapse the money, and this is a cash lapse.
That cash lapse is relevant, but it's not the same lapse that we use in our predictions because we need to do a number of accrual adjustments for liabilities, assets, and all that.
