Going by memory here, it's one of two things when there was a fluctuation in those years. One could be that we had some amounts that were statutory in certain years and an amount of money would come in that year to, let's say, pay a lump sum, a retroactivity adjustment or something like that which was done that year, so you see it going up, and it would go back down to normal afterward. That's one thing.
The other thing is that maybe in those years it was the strategic and operating review, the overall government reduction. Everybody was reduced, and we were asked to apply it within the organization. I think that was in 2011, but it may have been in the following two years before it fully impacted. Again, I am going by memory here.
