One of the major causes of fluctuations in the PCO budget is with respect to commissions of inquiry. Those are put into place at the prerogative of the Prime Minister. We have had several since 2006, including Air India. We've also had the commission of inquiry led by Judge Oliphant on the allegations on business dealings between Karlheinz Schreiber and the Right Honourable Brian Mulroney. We have also just established the Cohen commission.
When the commissions are established, their costs can be quite significant, so they will cause quite a change in our budget. There's also the Afghanistan task force, which is also an initiative scheduled to change at the end of 2011-12. We have had EAP, and we had the coordinator for the Olympics and G8.
So we have various initiatives that come in at short periods of time, inflate our budget, and then disappear.
