It seems there are two issues there.
One relates to the scale: can you get too large? In principle, the answer has to be yes. The practical question is where that limit is. If you look at our large institutions managing $100 billion, on a global scale it's actually not very big. ABP, in the Netherlands, manages $350 billion in its public service pension plan. TIAA-CREF, in the U.S., manages $350 billion. We're not at a stage yet, on the asset side, where we need to get worried, because we are international investors. That's one thing.
The other point you make around the federal government taking over liabilities really plays into this insurance question as to whether pension benefits should be insured. Of course, that's sort of an ex ante question. In principle, there's also an ex post question of what we do about where we are now. That's where you get into potential wealth transfer issues. The point is that whatever we do for members of registered pension plans, we must do the same for those who are not members of pension plans--holders of individual RSPs. You cannot look after five million workers and not look after the other five million.
