On your point about the rate-setting mechanism and will it tend to limit the potential to increase benefits, when the commission is looking at the rate for the future year, at that point, during that prior year, the minister can signal at any point her intent to make changes and the chief actuary needs to take that into account. So she can provide advice to the chief actuary that says, "I am considering making these kinds of changes. In your assessment of the rate I want you to take into account these kinds of changes.” So she would get a sense of what the costs were.
There is a mechanism to make sure that if the government has a plan to make a change in a future year, the chief actuary takes that into account in the upcoming year. Obviously, if a change was made mid-year, the impact on the actual revenues would probably be very small, because if you make a change mid-year, the actual cost is often out further. It doesn't really restrain the government at the time.
