We haven't done any exhaustive research on this. I can tell you in the States the movement isn't to deal with defined benefits; it's to go to defined contribution, which means, don't worry about what you're going to get in terms of a guaranteed income at the end, you'll get whatever your money generates when you retire. That's the movement, to go away from that defined benefit, which puts retirees more at risk.
