In terms of the assessment that we do regarding long-term sustainability and the comparisons to others, certainly PSPIB benchmarks itself against other pension plans in Canada. When it comes to questions of longevity and turbulence, these are all very much factored in as part of the work we do with the office of the chief actuary.
The PSPIB spends a lot of time working on these things. You'll find in their reports issues related to changes in salaries. I know the member had asked earlier about impacts of different labour relations issues. We factored in differences in salaries, differences in rates of return, differences in longevity. I think the last time we talked about the fact that there's a $7.7 billion cushion in there to deal precisely with questions like longevity. So these are all considered.
