Let me talk -- what I say is this, Vinay. We had a good quarter. Margin expansion is usually defined as the amount at which rate increase would exceed longer-term loss trends. It's kind of a hypothetical calculation at any given quarter. You never have a longer-term loss trends or something else. But if you look at where our third quarter result came from -- if you talk about earned premium, which is what gets into income, we were close to margin neutral in the third quarter in CPI and CSI and had about 2 points of margin expansion in CCI hypothetically. So by itself, it's a positive development, but not sufficient not to own [ph] to explain the third quarter accident results, so the 3-point overall improvement from the third quarter 2011. Where did it come from? A little bit from that, the margin expansion CCI perhaps, but more of that the actual losses in the quarter were below the regression line, between the -- below the long-term trend line. We'd like to think that, that's a largely attributable excellent underwriting on our part and maybe in part it is, but we also recognize there is some good fortune involved. And one of the pieces of good fortune, what we use as an example, there are other pieces that is non-cat related weather. That's primarily a Personal lines thing with a little bit of rollup to commercial property and multiple parallel lines. But for example, to give you an idea, in our homeowners business, non-cat U.S. related losses ran about 3.5 points in the third quarter versus 7 points in the third quarter of 2011 and about 6 points in the third quarters over the last 5 years. As you look forward, and I know all you will try to do this, you'd look at -- we might, at the continued rate levels, we might have theoretically 3 points of margin expansion in 2013 over all our businesses. But you have to remember, we're starting with a very favorable loss period. So it'd be kind of simplistic just to extrapolate that expansion. It would assume that extra loss experienced in the quarter will continue below longer-term cost trends for the next year, a possible but not probable assumption. And a more realistic assumption might include -- while setting the margin expansion, it's a little bit -- by some reversion to the mid and higher losses from a variety of areas. So margin analysis is a good forecasting tool. But you got to look at where the base period is, you got to look at the actual versus the theoretical. And then finally, when you look at income forecast, you got to recognize the margin expansion, it generally applies only to accident year results, it doesn't affect favorable development. And that's another major component of counting their results in order to take into account changes in investment income, of course.
