Mr. Chairman, we essentially apply the same standards to all the communities with respect to equipment. While there are guidelines to tell us approximately when it would require replacement, ultimately the decision is based on the condition of that particular piece and an evaluation of that particular piece of equipment. The guidelines we use tell us approximately how many hours of use on a piece of equipment gives us a guideline in terms of the amount we are prepared to spend on repairs for a piece of equipment of a certain age, but it is a general policy across all of the communities. Certainly on a small community in an isolated location that does not have backup equipment, we would be judging that particular case somewhat differently than a community that had easy access and where it was relatively easy to get in and get a mechanic and get parts in to do repairs.
In general, the standard or the guideline that we follow is, it really is a guideline, it is to help us forecast when equipment is likely to require repair. I know from my previous experience with Transportation that, in fact, we have done trades on equipment from community to community. If it looks like a piece of equipment still had useful life in it, but it was likely to require a higher level of repair, then we would move it some place where we had better support. It does not happen often because of the difficulties of moving large pieces of equipment around the territories, but certainly we have made some arrangements in the past where it seemed to make sense in that particular instance.
