As I mentioned, 2017 was the first year of commercial sales, so we are selling in oil well services. We're also aggressively pursuing different markets and I have to say that the biomaterial applications are growing very quickly. That is a suite of applications that we're finding a lot of success in. You have greases, paint, and coatings.
Regarding the high-paying manufacturing jobs, right now we are still ramping up, so those are plans for the future. We are crossing the valley of death, and it's a real situation for a start-up company where you have the technology and you have the investments, but there is a lot of risk involved. There is still a lot of process improvement that affects the cost of the material. Then there is integration of the material in customer formulation. It's quite complex, but as I mentioned, we're developing multiple applications.
