 And how do you make sure they actually disposed of the old buses and actually took possession of the new ones? We have a couple check-in points with all of the recipients for the programs. Our very first funding opportunity came out in the spring of 2022. And those folks will be wrapping up their projects in October of this year. And at that time, they will submit to us photographic proof that the old bus has been scrapped and that they've taken delivery.
