Yes. So the first thing I would say, Kai, it's all the normal stuff. Now, we're talking about very recent accident periods for a very long tail-line of business, so just as a perspective. At the end of 2016, we have paid less than 15% of what we believe the ultimate losses will be for auto bodily injuries. So, it's by nature a long tail-line of business, so it takes a while to play-out. We’re looking at all of the activity that we see, both in frequency and severity of loss, cut every which way you can think of, and looking at frequency activity, incurred losses, the paid losses. And importantly, we're also, as we went into 2016, we're looking at that coming loss of 2013, ’14 and early ‘2015 where we actually had slightly favorable development in the ’13 and ‘14 years, and consistent experience in the early part of the ’15 year. So we're looking at the history that we have coming into the year. As we went into ’16, we started to see a little bit of movement in the fourth quarter ’15 and early ’16, but still within our range of expectations. We got to the third quarter, and those periods, again fourth quarter ‘15, first two quarters of ’16, started to elevate above the expectations. Hence, we took the activity and the actions that we did last quarter. And this quarter, as we look at all of those periods. Again, now we’re looking at the end of ’15, early first three quarters of ’16, and obviously, now another quarter of data. We saw a continuation in that trend that was accelerating. And we took what we think was the appropriate management’s best estimate, given all of those factors. And we feel good about it but there’re certainly no guarantees that we can see what's going to happen next quarter. I mean, Michael, if you want to?
