I know John Deere just released a letter and I believe Case New Holland has one out and Caterpillar has one out as far as the amount of biodiesel they will warrant is concerned, if there is a warranty issue.
I don't know that number, as Howard mentioned, but we could get those letters and provide them to the committee afterwards. So there is a small percentage that most of the major manufacturers will accept now. I think because it is so new, they're doing a lot of research and development to continue to increase and expand that, and I think it's pretty safe to say that we will see the manufacturers grow that with the industry. I don't think they will lag behind.
Of course there's a potential challenge for the older equipment that's out there, but then warranty is less of an issue in that case; if it's an older piece of equipment, then the farmer doesn't have the same risk as using biodiesel in a new engine.
