I think it probably was generally the case in the past that when the federal government signed collective agreements, they were after the fact, after the expiry of the previous collective agreement. So we're always in this mode of retroactivity and making payments to departments for wage increases retroactively. You will still see in these documents some retroactive payments that applied before Budget 2010, and indeed there are still some collective agreements that are open.
The retroactivity only applies to agreements that were not completed in time for Budget 2010 and subsequent estimates and documents. Where we could advance the funds for collective agreements, the 1.5% increase for this year, prior to the operating budget freeze, we had to take out of the reference levels. This is really simply a series of adjustments, in effect to say that departments, as of fiscal year 2010-2011, will absorb the wage increases. That's really what you're seeing. That's where you see retroactive compensation. It's to cover those collective agreements that applied retroactively.
It's a bit complicated, but that's the explanation.
