Sure. Hi, Jerry thanks for the question. Within the transportation business, historically talked about 3 legs on the stool though the technology stack. The first being that we provide mapping, routing, navigation engines. Second, that we provide the back office technology for trucking companies. And third, that we provide the field mobility tools for companies. In terms of the booking and then those are the 3 historic legs of that stool. And then over the last couple of years, we've moved as well to address the shipper side of the market whereas historically this strength is on the carrier side. On the carrier side of the business, where we see the bookings, growth is in a couple of places. So first in that [Indiscernible] ERP systems, we called it a Transportation Management System and we're moving that business to a recurring model. So there's a model conversion that's happening in there. And we have seen evidence that we're increasing the size of the addressable market, which means we're reaching some customers that we hadn't previously reached. And that's translating into 20% plus bookings growth on a year over year basis in that part of the business. What we're seeing as well on the mobility side, which is really more of the EOD part of the business. As we have seen, some life there, both through two things. 1,... increasing penetration and existing customers as some of our existing customers, actually many of them are adding capacity given the market. In fact, they would like to add more capacity in many cases aren't able to actually get the vehicles are the drivers to do it, but that's one area where we see growth. And the others as we do see some logos are coming back to us, which has been a really good sign for us. Still a long way to go, but I'm liking what I'm seeing from the team, and the pace of the team, and the trajectory and that Canadian ELD certification was a nice proof point that we're not just talking about these things, that we are actually also are delivering. That mapping, routing, navigation business has had many, many years of double-digit recurring revenue growth, which means bookings continue to grow strong and they continue to do a great job in quarter-in and in quarter-out. [Indiscernible] up and that got to the commentary on the script. You asked Jerry about the churn rate as well.
