I would say, Tom, that the understanding of the different kinds of biodiesel is broken down to a very simple application, and that is what you would call, yellow biodiesel, which is what is non-distilled because it has contaminants in it, it has a yellow color, can only be blended up to about 20%. And so the customers that we deal with in India looking at this decision is do they buy a product that can only be 10% to 20% of their fuel, or do they buy our product, which is a 100% replacement, and in the wintertime it's an 80% replacement for the fuel in their tank. And so it's simple economics. It's either buy our product and you get five times the economic benefit, or buy a competitor's product and have a limitation on the amount of blending. Because we sell at a discount to diesel in India, an up to 10% discount, it can have a very, very strong positive financial impact on our customer's fuel budget. And the fuel budget in many of these companies is half of their total expenses. So, to be able to use five times as much of a product that has a 10% cost reduction is really the way they look at it. They're really not so much looking at it as being a higher quality, or anything else. They're basically just looking at the economics, as you would probably expect. I think over a long period of time you will see a bifurcation, a separation of customers: ones that require high quality supply chains with delivery, price, and product quality as being important to them; and ones that are driven purely by economics. And, quite frankly, they’ll take a lower quality product but blend it 5% and just throw it in the tank and save some money. And we have been focusing on the higher volume, higher quality customers, and that strategy has worked well. And I think over time the pricing advantage they have will be retained, but they'll be getting a very high quality product and will continue to be pleased with us as a supplier because of that. There is a story that hit a little bit in the media that was just, again, reiterating that you really don't want to blend more than 20% unless you're using our product. And one of our customers called up and said, we just decided to standardize on Aemetis. Universal Biodiesel is our India subsidiary. We're just not going to buy from any of these other vendors. We need that high quality product because it's what's going to allow us to have confidence that our trucks and buses are going to run all the time.
