I think the question is probably for both Public Works and for TBS.
On the TBS side, we felt we did have a way to measure the performance of the IRP. One of the things we looked at, as I said before.... Because this is a national joint council policy, we worked with the national joint council with bargaining agents. We did meet. We did discuss this. We monitored the relocation-related grievances, which, as we've said, went down significantly with the inception of this program. So from that perspective, we did have that, and it was with the national joint council that we determined that the quality of service is going to be paramount to the success of that.
That was, I'm sure, an influence in the 75% and 25%.
