Thank you, Mr. Chair. That one is actually a very interesting case, because that was one where there was an offset of new sites identified and costs, as well as reductions as we cleaned up our sites, so it netted out to zero, the impact that year; but there was actually activity both positive and negative that led to that point. It wasn't that there wasn't anything going on. It just happened to net at that level for that fiscal year. Thanks, Mr. Chair.
