Just one another footnote to that Mark, we have as we said in prior calls somewhere in the range of 13% to 14% share of what we define as the relevant market here in North America. That would be much smaller internationally, of course. We're watching small to midsize firms get in trouble, struggle. And I am sure, as has happened in prior recessions, we will watch many of these firms go out of business. As I said in my earlier remarks, one of our goals is to pick up market share. My personal opinion as to why we have grown peak to peak in many cases is that we typically are in much stronger condition, both managerially and in terms of financial resources, reputation, longevity, marketing reputation, et cetera, than the competition. So it stands to reason that as the competition shrinks, our opportunity to increase our share of the remaining market increases. As the market itself begins to come back, we're very well positioned to grow much faster than others. And so while there is no guarantee about the future, we fully expect to see a similar scenario play out this time. So I would certainly like to think that we could continue to grow reasonably well even under a prolonged agony situation such as you have described.
Mark Marcon – R. W. Baird: Yes. And I'm not saying that that is my belief, and I have certainly follow you I guess at this point, longer than anybody else, and realize that you have grown peak to peak and you continue to gain market share. I was just wondering, to the extent that people might be concerned that this is a longer downturn, and you have obviously demonstrated this last quarter, how well you are able to pare back your expenses, I'm just wondering if we go through a prolonged period, where it’s – it did take three years during the last downturn before things really started picking back up, if things take long this time around, you know, can you keep managing the expenses as you have been, and is that the philosophy, to try to keep expenses down, so that you can continue to generate a good operating margin over a two-year period? Or would your perspective be, well, we may go into a downturn where things are going to look, be a little bit rougher for a little bit longer, and we will take the lower operating margin, so that we can have – so that we can position ourselves for the upturn when eventually it does come, even if it does take longer than usual?
