Yes. Look, second derivative of, let's say, terminations, people leaving the system. Really the first derivative, it's been pretty flat. So I think generally the second derivative has been generally stable. It's not moving either way. In fact, I think that improved a little bit. It got slightly better in this quarter, so you would say the second derivative, I don't know, I'm trying to think of how that would work in terms of polarity, but anyway, it was favorable in this particular quarter. Now a really small amount, but generally, that's been about the same for several quarters now. It has been going I think -- I don't know I want to think back about 3 quarters ago, it had been up to then and had been going upwards, going the other way, had been rising, and maybe even up to the fourth quarter. It had been raising a little bit and so now it's kind of gone back the other way in terms of second derivative. So I don't know what to make of that, whether that's positive or negative. Generally, those things get driven by retirement. The difference between the -- what drove it upwards was retirements by people who had spent more times on the van, and they wanted to go to Hawaii or something for their retirement. And so those are the kinds of things, which are making the difference we saw more of those. I think this quarter, we saw rather less. Still up from, say, slightly from, say, 18 months ago, but down from, say, 5 years ago.
