Thanks for that question.
If you got through Mark's book, I congratulate you, because it is truly a tome in very small print, and there's a lot in it.
When you get into values, that strays from the strict mandate that we, as a pension fund, are intended to have. It was mentioned earlier that we have a very specific mandate with respect to long-term returns, and we practise best practices as part of it because we believe those are an essential part of long-term returns.
A lot of public policy and public behaviour goes into the values, which I would say is beyond the scope of what one can expect a pension fund to do.
