On the latter point, we really haven't seen an increase in production. And the second half relative to actually tons produced, we've seen increased shipments because there's been a lot of coal that was on the ground previously that shipped, but when you take it back to actual tons produced in the third-fourth quarter, they are pretty flat and we project that to continue into 2017. The only times that we really had going up in production are our own. We see about 3 million tons from us, we [technical difficulty] from others right now when you count them, there may be some that actually increased more, but there have been people that dropped out of the market in 2016 and won’t be there again. So net-net, as we looked at the overall increase in production for Illinois Basin in the northern half, we don’t see it going up, hardly at all. On the question of inventory, I'm of the view and this maybe a minority view, but I am off the view that the inventories are at the level they are right now because of the utility, buying strategies are going short. In other words, I believe they are increasing their inventory level to complement their strategy, trying to be short in the contract commitments. So when you look historically, I don’t think that’s a good measurement to determine where we are from a supply and demand perspective and I base that on the fact there were quite a few entries into the marketplace in the fourth quarter, that these utilities had what would appear to be sufficient stockpile capacity, but yet they were still buying tons in the fourth quarter to replace burn that they had in the summer. That was a little higher than what they expected. So, I may be wrong, but I am of the view that supply-demand is in balanced and I think the export -- increase in export demand in the last quarter is actually combined with the natural gas prices, this is -- it's the responsibility as to why the prices have been little bit better in the year November, December and January time period compared to six months ago. Personally, I think the inventories are going to be at these levels. Now each utility there may be some outliers, but it is a general statement. I think you're going to see inventories hanging around the levels they are today, as long as utilities continues to want to continue their buying practices of being short as opposed to meeting a longer-term. If they wanted to meet longer-term then they can pull that inventories down. With the cost of money, they haven't really needed to do that.
