Sure. Brian, jump in on this one, as well. I think, as we talk about the expense ratio, let's break at least for direct, or well for both I think is fine, into 2 pieces: acquisition and non-acquisition expense ratio. I think that's an important distinction to make. Acquisition, as you know, for agency is primarily commissions and we've been stable there for some period of time. Don't expect any major changes there. So that's a function really of earned premium. And on the direct side, we will spend, and we've gone through this discussion several times, we will spend what makes most sense relative to the yield that we see. So yes, that could go up faster than our premium under certain circumstances, but that would be based on good business judgment. The non-acquisition expense ratio you should reasonably assume has a great deal of management oversight that says we would need a really good reason to grow any expense faster than earn premium. So we should be able to continue to keep our expense ratio very much in the levels that you're seeing, at least, on the non-acquisition expense ratio. Something like benefits, not quite as controllable and may not necessarily be a direct function of earned premium, but we can control things like salaries, headcounts, certainly premium taxes, those sorts of things. So while you've seen that go down over time, that's been a very deliberate action for us to get to something closer to the run rate expense ratios that you're now seeing on a pretty consistent basis and that the trend being a favorable trend. The biggest change that we will likely be able to bring about in our expense ratio will be continuing to increase policy life expectancy and having more and more of our customers with multiple products. That denominator effect, if you like, or scale effect, is the one that will give us the next quantum. But the active management, which has been going on for some time, to control non-acquisition expense ratio has frankly been extremely positive and got us to a level that we feel very comfortable is sustainable. But for some really exogenous event like benefits costs or something like that which is not likely to move the needle significantly anyway. Brian, anything in that...?
