 That's an interesting question. The IATF16949 quality management system standard is written with a scope of applicability to OEM parts suppliers. So if you are making an engine as an aftermarket replacement that will be sold as GM Goodrich parts or Ford branded or Mopar branded parts, then it would require certification. However, generic brand parts that aren't sold under an OEM brand don't, which is foreign to me of how the logic for this was developed. But, you know, let's just take something a little bit simpler than an engine. Let's just take a starter motor, for example. If I'm making that starter motor to be sold as an OEM manufacturer brand, I have to be certified to the IATF standard. If I am selling it as a generic no-name brand through the big box stores like Napa and Pet Boys and the like, then I don't. Personally, I don't see that practice being one that will stay around. I think eventually everyone will have to get with that program because the load don't change based on the name on your box. It is a standard that applies to Tier 1 all the way down to Tier 2, Tier 3. Different manufacturers based on the risk of what's being incorporated into their assemblies will roll those requirements down to lower and lower levels within the supply chain. I bet if you were to do a deep dive at Michelin, for example, it makes tires, they probably apply some degree of control all the way down to the rubber tree farmer in Brazil. Right. And they are very, very, very controlled operation. And so, even the farmer raising the rubber tree plants is going to have a quality management system in place. Different components in different parts, they manage it a little bit differently, but it's a pretty solid bet that all the Tier 1 and Tier 2 will be following that and most Tier 3.
