Mike, it's Mark Wilcox here, I'd be happy to address your comments. And then, obviously, Greg and John can jump in as well. But you're absolutely right, if you go back about 5 years, we were closer to the industry average from an expense ratio perspective and we did see that drift up towards -- sort of peaked in terms of a high point or a low point, so to speak, at the end of '16. We've made good progress in '17 in terms of driving the expense ratio down. And certainly in 2018, we've made excellent progress, we're down, I think it's 110 basis points in the quarter and 130 basis points on a year-to-date basis, so making excellent progress there. We are mindful to focus on the long term not the short term. We're not looking to build any expense deficits in terms of the infrastructure and the investments we need to make in the technology to support the strategy and the future growth of the organization, but we have made good progress on the expense ratio. A couple of things I think that are driving it, one is we have benefited from good growth over the last couple years. We've been disciplined in terms of being able to manage our headcount and infrastructure expense growth, and we've grown that at a lower rate than the overall expense ratio -- or the growth rate in premium. And we've been able to drive the expense ratio down. I do think it is good to split the Commercial Lines expense ratio from the Personal Lines expense ratio. Personal Lines does run at a -- from an industry perspective, at a lower expense ratio than Commercial Lines and we're very focused on driving that down. I think overall, going back to your comments, from an industry perspective, we still are at probably a 2 to 3 point expense disadvantage compared to the industry as a whole. There is an element of a higher level profitability for Selective versus the industry and some incentive-based compensation in there, whether that's employee or supplemental commissions, that probably adds about 150 basis points to our overall expense ratio. So if you normalize for that, you'd probably cut that deficit in half. But overall, our goal is to drive the expense ratio down. In the past, we had a target out there, more of on a statutory basis, of about a 33% expense ratio. I think longer term, from our perspective, we would expect to focus on driving our expense ratio down on a GAAP basis closer to the industry average, which is about a -- call it about a 32% expense ratio consolidated.
