I wouldn't have a whole lot to add. For us, it is an ongoing effort to modernize our operations and take advantage of new technologies, as they become available, that change how we do and deliver some of the services. Often those things require pretty significant up-front investment, but once we have it in place, it can generate savings for us.
If I look back over the last five, six, or seven years, for part of that period we have been able to keep those savings and reinvest them in other things to offset higher fuel costs and various other things. Some of them did become some of the expenditure review committee reductions that were announced, so it's a mix of having been able to keep some of them and some having gone to general funding.
