Yes, I can. Let me start by saying on an annual basis, on 12 months, if you look at 2015 to 2014, we actually had pretty darn good operating cost leverage. Using that 15% target, if you look at our growth in revenue and then if you take out the gains from last year and the gains from this year, our operating costs were pretty good. And in any individual quarter, they may have been an increase or reduction in cost. But on an annual basis, the operating cost was pretty good. Where we have struggled is the gross margin line on an annual basis and then really throughout the year, that's where we struggled. In the December quarter, we had a spike in big boat sales. And when I say big boat, above 75 feet, 80 feet or bigger. Those carry low double-digit margins, 10%, 11%, 12%. So that drove our margins down. That's what we talked about in that quarter. In the March quarter, we had elevated marketing costs and elevated health care costs to your point. Now I will tell you on an annual basis, we made up those costs basically. But in the March quarter, we had elevated costs. And then we also had a mix of older Sea Ray product -- to be replaced Say Ray product selling, which drove down gross margins. So now that's the second quarter where margins dropped and expenses were higher in that quarter. In the June quarter, it was a lot of these trades selling that we talked about from the December and the March quarter growth that we had of 35%. Those then sold in the June quarter, which hurt our consolidated margins because used boats and also wholesale boats, to Bill's point, carry lower margins than new boat sales within other margin businesses. Cost leverage in that quarter was pretty decent in the June quarter. In the September quarter, we got a little bit of a tail of used boats selling through. Costs were pretty good. We had some elevated marketing costs, some elevated commissions. But generally, costs were pretty decent. And that kind of wraps up the year. If you look at 2014, we had good margins and very good flow through. So we've had some challenges here in '15 that we certainly are working hard to overcome.
