Sure. That's a difficult question, I'm sure as you know, at this point in time and that we've been careful about disclosing of what we thought in the past, careful about disclosing what we thought spot pricing was because early in our experiences, as a publicly traded company found that worked against us relative to our competitors using that data. But I also recognize your challenges and your colleague’s challenges and viewing the company. So we'll do our best here to try and provide as much color around that subject as possible. So having said that, one of the things that have happened is absolutely, spot pricing has lowered today from what it was in Q2, and Q3 has been a downward trend to be clear. However, at the same time, the disparity or the distribution and standard deviation, if you will, pricing around the world has grown. So there's somewhat of a disconnect from region to region to region, about what those numbers were. So if I gave you an average price today, of where we thought it would be, it would not be, candidly wouldn't be terribly useful for you because it would be different price in the U.S. and a different price in the EU and a different price in the Middle East and yet another one again in Japan and Korea, etcetera. If the distribution of the change disparity from region-to-region has grown as the price has come down. Now, the best way that I think we can help you think about that, is that if you look at the information that is publicly available and that is the export import numbers on needle coke, you would find that that number, recently has a range as well, but it's anywhere from a few trades, not many, but a few as low as 1,300. And more is about the 1,800 level. So I think in the past, we've given a lot of information about how to take those kind of numbers and translate back into cost structures. And so, if you have a graphite electrode, so for our counsel would be given that for the reasons I've stated previously that we're not going to come right out and tell you what we think prices are on graphite electrodes, I think you can use that needle coke number. And think about that in context of the incremental cost that people are facing now on electrodes and knowing that that's probably pretty close to the bottom range, won't be practicable. I hope that's helpful.
