If you look at how the situation evolved from 2008 to 2011, you will see in our report that many factors have affected the funding status of the plan. One item was, of course, the investment losses of 2008 and 2009. But another aspect of it is...I changed the assumptions of the real rate of return. In the 2008 report, it was 4.3% in real terms; now it's 4.1%. Obviously the minute you reduce the expectation on the discount rate, you increase the liability. This also explains the size of the deficit.
Moreover, for the first five years of the projections, we recognize that interest rates are very low, and we have an assumption that is lower than the 4.1% we had for the first five years. There are all these factors, plus of course since the past decade, let's say, public servants are living longer. Even if in previous reports we had improved our future longevity, we still have more than what we expected in the past. This has also contributed to a higher deficit.
