We'll try to assess that when we do our market study.
What companies are doing generally, day to day, is something that we would be studying mostly in our enforcement mandate when we review the specific facts of a case. Our reviews of mergers, for example, are obviously based on evidence and facts, but they're looking at very specific conduct that is happening in the marketplace. I don't think we're in a position to make a general statement today in terms of a trend in the industry, but certainly it's something that we'll be thinking about if our proposed market study moves forward.
