It's a good question. Ultimately we tend to do costings and enlist the services of the office of the chief actuary to support us in doing that kind of analysis only on an as-needed basis. It costs the plans money to perform these kinds of service, and there are a lot of different proposals that are put forward for changes to the plans, so unless something is being put forward for consideration by the government, we tend not to ask the office of the chief actuary to undertake this work.
