Sure. Thank you, John. And good question, Mike. So as John mentioned, we stayed on plan. And as I mentioned in my prepared comments with the 2020 accident year from a loss ratio perspective for the longer tail casualty lines, essentially, the only frequency benefit that's come through has really been through the premium credits that we gave back in Q2 for the commercial and personal lines. When you do look at the underlying combined ratio, it is very strong. Year-to-date, on an accident year, ex-cat basis all-in we're at 90% underlying combined ratio. You might recall that last year, we were 92.9% and as we projected our full year expectations at the end of January, our forecast for this year was at 91.5%. So we're fully better than last year and showing margin improvement from initial expectations since the start of the year. But it is a noisy year. There are a lot of moving parts to the underlying combined ratio. A couple of things I'd point you to when you look at that 90%. One is, there is a little bit of a drag associated with COVID-19 embedded in that 90%, and that's 1.7 percentage points, as I mentioned in my prepared comments. So if you back that out to, you're kind of down to 88.3%. But relative to our expectations of what we think non-cat property should run on a kind of a normal year-to-date basis. It's about 1.2 points of benefit from non-cat property. And then from an expense ratio perspective, I would characterize some of the benefit that we've seen on the improved expense ratio ex-COVID-19, it's a little bit of a onetime benefit from the work-from-home environment, the lack of T&E and of course reduce incentive compensation as the ROE is at a year-to-date versus our target of 11%. So that's about point of benefit. So when you put that all together, year-to-date, we're kind of from our account, sitting on about a 90.5 underlying combined ratio. And then when you go back to the guidance that we issued last night, we gave you the ex-cap guidance and you take the favorable reserve development, that would book year-to-date of 2.5 points, kind of normalize that over the full year, it's about two points of benefit that would get you back to about 90% to 91% underlying for full year 2020, and kind of back to kind of the midpoint of what we're seeing on a year-to-date basis at the 90.5%. So hopefully, that's helpful, a lot of moving on this year with COVID-19 non-cat property as well as the expenses, but certainly some strong underlying margin improvement we've seen this year.
