We're looking at efficiencies all the time. The pay modernization project is one such project that should bring enormous efficiencies in the future. We're also doing modernization of our pension delivery system in terms of the basic information technology that goes behind it.
In addition, we've got some really path-breaking work when it comes to basic HR business processes. A concern in the past has been that departments go at their internal systems alone, independently of one another, which can be a costly way to do things. What's quite exciting about the project that's under way is that departments have collaborated and have decided on a common business process governing HR. They have further design work to do, but it will become the foundation, let's say, for a streamlined, efficient, and, I think, hugely cost-effective way of proceeding on HR.
