One of the key risks remains the size of the plan relative to that of the organization. Even if solvency were to disappear, the going concern obligation would still represent a very large percentage of the revenue of Canada Post and we expect that to continue to grow. Fluctuations in that financial position and the contribution requirements that could arise from that could be difficult for Canada Post to bear.
I will say that projections or estimates of Canada Post's future revenue prospects is outside of our area of expertise. I believe others have looked at that, but we know that there are pressures in that regard and, if revenues are not rising, it would be more and more difficult to sustain the plan.
As I mentioned in my remarks as well, the going concern funding that we have in place in addition to solvency is based on a set of assumptions, and they are only that, assumptions.
In particular, two of the largest ones would be the return on investment and how long people live, their life expectancy or longevity. If either of those do not pan out as we've assumed, we could end up in a deficit position, either temporarily or permanently if we alter the assumptions at some stage to reflect a growing understanding of reality or change in the circumstances. So the risk that's taken.... In fact, the plan, it's invested in equities at the moment. Some portion of the plan is invested in the public equity market, which carries a good deal of risk, because as you know, stock markets are volatile. We do expect that that sort of investment will pay off in the long run, that it will provide higher returns, but it's not guaranteed.
