 Yeah, cost avoidance is a big one. The OEMs do not like it. We've built a very good program around cost avoidance because when you do cost avoidance, that means that we're utilizing an asset for a longer period of time and or in a different arena. And when you do cost avoidance, that means someone's not purchasing a new device. So as an example, we run what's called a B-Stock program where we're supporting customers with the own devices they have.
