I will start, and my colleague will complete my answer if need be.
There's a partners committee, with the support of the administration authority. That's how we receive information on an ongoing basis on how the plan is doing. For example, for years we heard about how many appeals we had received. This is very helpful information, because we know where the pain points are in the plan. Then there are the number of requests the administrator gets. We do get reports from them. Those give us a sense of how the implementation is going.
Then we have research and analysis done for the partners committee on the various areas of the plan. It's mostly on what is newer. This sector advances and progresses at such a high speed that we have experts coming in and discussing it with us.
Then bargaining agents bring what they think are the key elements from consultations with their members. We also have discussions internally with the employer and certain experts in the system to see what would respond to needs.
I'll give you the example of mental health. We saw the trend with disability leave. For the community, we knew this was an issue we had an opportunity to better address through these negotiations.
This information, in addition to the benchmarking study and the analysis of what is made available elsewhere, informs the negotiations.
