I think the most obvious one is the reporting requirements. That is, the pay equity plan needs to be reported. That was one of our recommendations. There need to be periodic reports from an employer on the picture under the plan as they've implemented it, and then some kind of monitoring of the results of that to see whether the gap is narrowing or whether it's for some reason staying stagnant or even widening again.
