All right. Thank you for that, Amit. This is Jack. I'm going to kind of talk about it at a high level and then I think Dick has some few thoughts that he wants to share. As you look at Slide 6 in our presentation, we really thought it was appropriate to remind everybody that the increased severity that's in making its way into the liability lines, obviously, first in Commercial Auto in a pronounced way, is something that we've been wrestling with and the industry has been wrestling with for a number of years. But if people will recall, midway through 2018, we saw some elevated losses coming through, particularly in the auto area that caused us to make some adjustments and -- in our picks, in our pricing, in our underwriting. We also want to remind folks that, 3 or 4 years ago, we were maybe one of very few companies that was identifying some CMP liability claims patterns that looked challenging to us. At that time, if you remember, we talked about losses that were primarily slip, trip and fall type losses in the major metropolitan areas, although you could see some of it in some of the more challenging litigation environments. So all of this was a way for us to kind of say, how do we share with folks, what we've already told you about the improvements that we've made in the portfolio, and then some contemporary things that we're doing to address the mix of the business, both sector and geographically? The last point I would make just is about the issue around the limits profile of a company. I would tell you, in aggregate, mathematically, this problem exacerbates itself as you move up the limits profile. Is there some evidence that you're seeing more and more litigation and activity at lower levels of the business? I think the answer is yes. And we talked about that a little bit in our Personal Lines business that we're even seeing some evidence of some change there. But mathematically, from a loss ratio standpoint, it gets very much exacerbated if you're a higher limit player, if you have a huge umbrella book of business. And so Dick, do you want to provide some color on that?
