So, I guess several questions in there. Beginning first with, obviously, the rising cost, especially in nickel has not gone unnoticed. For us, because we're more in the development phase, at least in the near to mid-term, the cost of nickel and of course, associated with that cobalt, are less impactful and that's just merely an artifact of we're just not procuring nearly to the degree of volumes of materials that for example, the established Tier ones are. Again, that is in the near to mid-term. Now that being said, assuming that these cost pressures continue out to when we were at sales started production and vehicle started production, with our generation-one cell will have really the same exposure to those costs, because again, we're using the same nickel and cobalt cathode active materials. Now for the long term, on the R&D side of the house, we have a fairly robust activity right now around developing a non-nickel, non-cobalt cathode active material, that is essentially made up of very, very abundant and low cost materials. Now, again, it is R&D, so it need some further development. But, assuming we are successful and this is really why I personally am so excited about this, that could obviously eliminate those - that cost exposure, risk exposure, to those nickel and cobalt costs in the future. So again, we philosophically do have a long-term vision of looking to displace that nickel and cobalt containing cathode active material, again, with extremely low cost earth abundant materials, that by the way the reverse-ability of those cathode materials is unique to the solid phase. So in other words, in a traditional liquid or gel that would not be a rechargeable so. I think you were asking about, do we source some of our precursor materials? I think you were referring to specifically Eastern Asia. The short answer to that is no, we do not.
