Michelle Ostermann:

The biggest example is a macroeconomic shock that would affect the solvency of corporations. The failure of the corporation itself is more likely to have an impact than just a change in interest rates or equity markets. The change in interest rates can affect the fundedness of a scheme, but many of those schemes, over 75% of them now, are actually really well funded. And they have pretty well locked down their interest rate risk because they have put a good chunk of assets against their liabilities in a fairly tight hedge. Although we saw, as a result of the liquidity crisis a few years ago now, that things can change. The degree of risk, specifically leverage risk inside some of those strategies, does make them fallible. I would say the biggest shocks would be massive interest rate movements that are unforeseen, a very significant macroeconomic environment causing failure in many corporations, and technically, even a significant move in equity markets, but we would usually just ride that out. Markets can go down 20% or 30%. We would only go down 10% or 15% and we would be able to recover that in under five years, historically speaking.
