Thank you very much for the question.
Under the existing legislation, there is already a requirement that the plan be invested in a way that it works towards the goals that are set by the chief actuary—in this case, 4.1%—in a way that doesn't bring undue risk to the fund.
We recognize that we need to go beyond that and do a funding plan. We've begun work on that. When we did the significant changes related to sustainability, in 2012, that was a considerable amount of work to make sure that we got that right for what is probably the biggest, or at least one of the biggest, pension plans in the country. The funding plan work has not advanced as quickly as it would have had we not done that, but we continue to work on that, and we expect to have that done sometime in the next fiscal year.
