Yes, what Mr. Matthews said is accurate. You'll recall that departments can automatically carry forward roughly 5% of their operating budget, and not always but in most cases, they carry forward something similar to that. Each year when we do the budget forecast, we do an estimate of the amount of money that departments have been allocated that they will not spend, and we try to update that over the course of the year by surveying the chief financial officers of every department.
Although I can't give you an exact answer on your question, my suspicion is that a fair portion of the lapse you are referring to would have gone into the better than expected deficit outcome.
