Sure, absolutely.
In the administration of our vehicles regulation, we actually undertake the vehicle testing. We also work collaboratively with our partners in the United States. We actually have a shared testing program, and we share testing results. We were starting to see this information surface, particularly with the study that was done by the ICCT. Then we started to undertake purchasing and acquiring of vehicles so that we could put in place a testing program for them. Because of the nature of the defeat device, as we now know, it was programmed into the operation of the vehicle. What it did was this: The computer program would recognize that it was on a test cycle and would tell the vehicle to put on all its emissions control devices, but when the vehicle was on the road, it would take them off.
