Now, let me introduce Tony Will, our President and CEO.

Thanks, Dan, and good morning, everyone. Last night, we posted fourth quarter and full year results for 2015. For the fourth quarter, CF Industries generated EBITDA of $254 million and full year EBITDA of $1.7 billion. After taking into account hedging losses and impairment loss on our Trinidad joint venture equity investment, costs related to both the CHS Strategic Venture and the OCI Transaction, and expenses related to the expansion projects, adjusted EBITDA for the fourth quarter was $451 million and adjusted EBITDA for the full year was $2 billion. Despite difficult market conditions, we generated gross margin of over 25% in the fourth quarter and over 35% for the year. If not for the unrealized mark-to-market losses of roughly $100 million on natural gas hedges, our gross margin for the fourth quarter would have been approximately 34%. And if not for the unrealized mark-to-market loss of approximately $175 million, our gross margin for the full year was roughly 40%. Our quarterly and full year results continue to demonstrate the cash generating capability of this company. We consistently deliver solid results because of our cost advantage position within the industry, despite the fact that the global fertilizer market is oversupplied. In several production regions of the world, currency devaluations and other factors have reduced costs for high-cost producers, some of which have continued to run despite negative margins, leading to excess supply. As a result, there has been downward pressure on prices. Urea transactions have been reported at price levels not seen in the decade. However, even against this backdrop, we still delivered full year adjusted EBITDA of $2 billion. Our business is not like other commodities. It shares little to nothing with iron, steel, copper or coal. A country or region with a slowing economy may stop building skyscrapers,…

Thanks, Tony. The global nitrogen market continues to be supply-driven, with increased availability of internationally sourced product pressuring prices. During the fourth quarter, prices for all fertilizer products declined, including nitrogen. Excess supply around the world and new capacity coming online, all helped to push the market lower. Urea prices declined throughout the quarter, decreasing from a high of $260 per short ton fob NOLA at the beginning of the quarter to $220 per short ton fob NOLA at the end of the quarter. As Tony said, very little business was done at these low levels, as the market was highly illiquid. During the fourth quarter, the Chinese government allowed the yuan to devalue further, continuing a trend that began in the third quarter of 2015. When accounting for the devaluation, along with a decrease in coal prices and continued weakness in ocean freight, cash costs of urea production for the marginal Chinese anthracite coal-based producer are now estimated to be near the seasonal low of roughly $225 per short ton delivered to the U.S. Gulf. As Tony mentioned, production rates in China are declining and some high-cost producers have already curtailed production or shut down altogether. Exports out of China were 1.5 million tons lower in the fourth quarter of 2015 compared to the same period in 2014. For the full year 2015, exports totaled approximately 13.8 million tons, which is slightly higher than the full year 2014. In the U.S., industrial ammonia demand was impacted by lower phosphate production and the fourth quarter agricultural ammonia application season was negatively impacted by weather. Warm weather into early November, coupled with the combination of rain and snow later that month, limited most of the Midwest from getting applications completed. In addition, customers were reluctant to buy urea and UAN during…

Thanks, Dennis. Before we move on to Q&A, I wanted to review our near and longer term outlook and the significant benefits of our strategic initiatives. As we have already discussed, our business continues its strong operating performance, delivering $2 billion of adjusted EBITDA in 2015. Looking at the fundamentals, the cash margins for North American producers are in the 50% to 60% range even with today's market conditions. Against this healthy backdrop, over the next roughly six months, we are about to grow significantly, adding 60% new production capacity to our portfolio with very similar margin structures to our current business. We are investment grade and have a very strong balance sheet, having just received $2.8 billion in cash. Our spending on the capacity expansion projects is quickly coming to an end, as we expect to be fully mechanically complete within the second quarter. Our business combination with OCI is expected to deliver roughly $500 million annually in after-tax full run rate benefits. And we expect our longer term effective tax rate to drop from 35% into the low 20%s, making us that much more efficient at converting EBITDA into cash. Finally, bonus depreciation will provide us significant cash flow benefit this year. The bright future we've been talking about is arriving now. This is a lot of very positive change all being delivered in a short period of time. However, one thing is constant through it all and that is our focused strategy for driving total shareholder returns. Our goal is to grow cash generation per share and our capital allocation philosophy flows from that. We first look to grow our cash generation, the numerator in the equation. We do that with investments that have risk adjusted rates of return well above our cost of capital and only if they drive cash flow per share accretion. Otherwise, we look to reduce our outstanding share count, thereby reducing the denominator in the equation. Consistent with our past actions, all excess cash will be returned to shareholders, but we are fully committed to maintaining our solid investment grade credit rating. As we look forward, we believe there will be significant cash available for deployment. We will do that consistent with our singular goal of growing cash generation per share just like we have in the past. I want to end today's call by thanking all of our employees who have worked so hard, not only on all of our strategic initiatives, but also keeping the core CF business running so strongly on a daily basis, while delivering our best ever safety performance, a truly remarkable accomplishment. Many of the steps we have taken are already showing results and I am excited that the next six months should see all of our initiatives, move from planning and development into actually delivering cash flow to the bottom line. With that, we'll now open the line to answer your questions. Operator?

Thank you. Our first question is from Ben Isaacson with Scotiabank. You may begin.

Hi. This is Carl Chen stepping in for Ben. Thank you for taking my question. So we have seen an incredible rally in the urea prices over the past weeks owing to the prospect of an early spring. Can you please also comment on your expectation for the strength of the ammonia and the UAN pricing recovery, given that Mosaic decided to curtail that production in Q1, and this early spring could reduce the need for UAN side-dressing?

Carl, I'm going to ask Bert to take that question. But just one observation, when you talk about an incredible rally in urea, I mean the observation I think that a lot of us around the table would make is that the trough pricing that was reported in January was a little bit artificial. It doesn't really reflect where the market has any kind of liquidity or volume. And that's one of the reasons why it looks like it'd come back because the minute there was any sort of demand it rebounded to what the real value of the product is. But, Bert, do you want to handle the -

No, I agree with you about the urea market. It has recovered probably to more of a normal price range. And I think we have an anomaly like you said, very few barges were traded at those lower levels. And we know that because we entered the market to buy a few and they were not there. I do anticipate we are seeing now probably the opportunity for an early spring. Applications have already begun in the Southwest, Texas, Oklahoma, and the temperatures this weekend are very conducive to continue that activity. And I think as you see that warming trend move through drying trend, throughout the Midwest, I would think that within a month in the upper Midwest, that being Nebraska, Iowa, we may even see applications beginning then. You're correct that a lot of the ammonia stays within the producers hands and is available to the customers, those being the retailers, which then sell to the farmers for application. And I think the order trend has been a little bit different than in previous years, but the feedback we're getting from our customers is that there will be significant demand. We lost a lot of ammonia applications in the fall just due to the weather issues we articulated and so that – and it will still be needed to be applied. And so as you move that to spring, we're going to need almost a record ammonia season in order to fill some of that nitrogen demand, which I think will be difficult. And so for your comment on UAN, we believe that's going to fall either to urea or both the urea and UAN. And we're positioning our products and our terminals with our customers for that eventuality that we're seeing a pretty healthy market going forward for nitrogen on the demand side and a parallel positive position for pricing going into and through spring and even on the back half.

Perfect. And then, maybe just a follow-up question. We have seen some reports indicate that Chinese urea producers are producing below costs and stockpiling in the anticipation of a strong spring application similar to last year. If this spring application disappoints in China, do you have a sense of how this residual inventory could weight on urea prices abroad?

Today, the indications we're getting out of China are that the terminal and the port inventories are lower than normal. And that makes economic sense. As what we said in the comments was we believe that the Chinese producers, a majority of them, have been operating at or below costs. There is very little incentive for them to push products to the ports. So we're seeing the Chinese industry operate rationally. And according to economic principles, eventually gravity does work even in China. And so, when you look at today what's going on in China, wheat top-dress has begun in China and you're seeing product move into those markets. Today, the domestic price is better and there the incentive then is for the Chinese producer, the urea producer, to keep that product moving to the interior. And then, they'll probably look to the export market as we move through spring. Today, if you loaded a Chinese vessel, let's say March 1, and we're sending that to the United States to New Orleans, it would probably be a 45 day voyage and then discharge arriving in mid to late April, and you're starting to get a little bit late. There have been some Chinese vessels sold for this spring and we think they'll arrive in late March through early April. But once you get past April, it's difficult to have that product be applied for the spring and post planting season.

Great. Thank you.

Thank you. Our next question is from Steve Byrne with Bank of America. You may begin.

Yes. Thank you. Bert, do you have an estimate of how much nitrogen inventory is in the retail channel now? And how does that compare to historical levels for mid-February?

Yeah, Steve, good morning. It is a little bit anecdotal, but we do spend a lot of time trying to determine what the physical inventory position is, whether that'd be dry on urea or UAN in the tanks. Most of the ammonia is sitting with us or the other producers in the terminal system throughout the Midwest. And so, what we know just based on imports and production levels of UAN, we expect that those levels are lower than historical due to the fact that we trended into fertilizer year 2016 at a low level of inventory entering that season and then the production and imports together with that build our number. On urea, I think there's a sufficient inventory to begin the season. You can look at the import numbers and then, again, at the production numbers and our production numbers. So there is enough probably in position, but is in the right position, and then the second round of product that needs to be available. And I think that's why you've seen this rally is the scramble to get product in position.

And how would you characterize those customers of yours? Are they fully engaged now in rebuilding inventory for what you described as that second round or some of them still on the sidelines?

It's like a family. Everybody has a different opinion when you sit around and talk politics, same thing about inventory on fertilizer. We've just participated in a TFI and met with a majority of our customers and we had the whole range of opinions of, I'm not going to buy until the farmer comes in to purchase and they'll pay the appropriate price at that time to those who have prepared and we're anticipating. And so we're working with each of our customers at their risk level or their risk appetite, and some of that inventory has stayed with us and we're quite fine with that because we believe in the size of this spring application season and the need for this product will be probably very robust.

Okay. Thank you.

Thank you. Our next question is from Adam Samuelson with Goldman Sachs. You may begin. Adam L. Samuelson - Goldman Sachs & Co.: Yes. Thanks. Good morning, everyone. Maybe a question on the UAN market, if I will, I mean, you've had a pretty big spike in urea in the last 10 days or so. And I know, Tony, you said, hey, that was depressed in January and there's very little volume there, but at the same time the UAN market trended down in conjunction with urea. And if I look at spot pricing, I would say that urea is trading at a premium on an end value basis to UAN, which seems unusual. And so I'm trying to think about, A, how your order book on UAN looks prospectively, given there's less dependence on imports there? And B, how you think about the balance between the two products on an end value basis as we go into the spring?

Yeah, good morning, Adam. You did see a movement in UAN in January. We readjusted or adjusted our prices at that point, but the urea market stayed very steady July through into January. And there was a reflection on an end basis at that time to move UAN more in line with urea. But as you've seen urea move up, we've seen a demand build for UAN and we believe that will continue through spring. UAN's a great product. It's so versatile and how it can be used, not only in wheat and corn. And so, I do believe that you're going to see a price increase or a value increase going into spring for UAN as well. Adam L. Samuelson - Goldman Sachs & Co.: And as you look at your own order book today versus prior years on UAN, would you say you're ahead of last year, behind last year, or any comments there?

Yeah, every year is different. And so it's more of you can be ahead or behind them, I'm not sure if that's as meaningful as what the value associated with the product and the gas price. So we're pretty excited about the level that we're able to buy our feedstock. And I would think that at these lower levels, it's not as attractive to us to sell. And so we would prefer to wait for some appreciation. Adam L. Samuelson - Goldman Sachs & Co.: Great. Thanks very much.

Thank you. Our next question is from Vincent Andrews with Morgan Stanley. You may begin. Neel Kumar - Morgan Stanley & Co. LLC: Hi, good morning. This is Neel Kumar calling in for Vincent. I was just wondering if you could speak about some of the inputs you're assuming to build up to the marginal cost figure of $225 per short ton, specifically in terms of anthracite coal prices, freight? And also, can you just talk about how these inputs have changed from your 3Q estimate of marginal cost of $250 to $285 per short ton? Dennis P. Kelleher - Chief Financial Officer & Senior Vice President: Yeah, sure, Neel, this is Dennis Kelleher. I'm just trying to get to this slide that you're talking about here in the deck. What we've done here is basically what we look at is, basically all of the costs that exist at the plant site, and that includes cost to ship the coal to it, the costs at the plant sites that are incurred and the cost to ship that product to the port, and then, obviously, to load it so that it can be loaded on the boat and shipped to the U.S. Gulf. So all of those inputs, sort of from the coal mine all the way through to the product arriving at the U.S. Gulf, are included here. And what we do is, on a regular basis, we're going to update that for everything from Chinese exchange rates to Chinese coal costs in addition to that to freight rates, and we do this across the curve. And so what's happened, if you look at sort of where we've come to is you've seen a decline in coal prices, but you've also seen a decline in the RMB exchange rate, and we've also seen a decline in shipping rates. And so that's what accounts for sort of the shift to downward in what we call the seasonal floor price range. And I want to be clear that this is a seasonal floor price range because we're saying it's $225 to $270. And what we do perhaps differently from the way other producers look at it is, we look at the fluctuations in monthly off-take for urea. And so during low periods, you'll see lower prices like we've seen here in January and February. And then, during high periods, like when you get into the spring, it takes more dollars to bid the more expensive marginal producers into the market. But that's basically how we do this. We look at each of the bars here in the cost curve and we will update that. With respect to China, we've got a lot of insight because of studies that we've done on a plant-by-plant basis. And so, we will update the cost on a plant-by-plant basis for the various subsets of their producers.

But to be specific, we're assuming $115 per metric ton (31:41) coal and using RMB exchange rate of $6.55. (31:49) Dennis P. Kelleher - Chief Financial Officer & Senior Vice President: So that's $6.51this morning. Neel Kumar - Morgan Stanley & Co. LLC: Great. That's pretty helpful. And there's a quick second question. I was just wondering if your thinking has changed at all in terms of target leverage. I know previously you had mentioned 2 to 2.5 times.

On the leverage front, we're still 2 to 2.5 times. I think as we get through the OCI transaction and reduce our effective tax rate, you could argue that the same amount of EBITDA actually goes farther because we're much more efficient at converting EBITDA into cash. So you can see maybe another half turn of additional leverage that we could take on, so somewhere in the 2 to 3 times range, I think, is probably reasonable, but we haven't socialized that necessarily with all of the rating agencies and so forth. And our view is always, we want to maintain solid investment grade rating, but have an efficient balance sheet. So we're going to thread the needle on those two constraints. Neel Kumar - Morgan Stanley & Co. LLC: Great. Thanks.

Thank you. Our next question is from Joel Jackson with BMO Capital Markets. You may begin.

Hi. Good morning. I wonder if you could give a couple of updates on methanol and the Natgasoline project. Where are you in your thoughts on that commodity and if that is something you want to keep in the deal? Thanks.

Good morning, Joel. So, as we've talked about in the past, there is a closing condition for Natgasoline that it has project financing. It is a very difficult project financing marketplace out there right now. And so in the last, that was able to satisfy the closing condition or we otherwise wave it, then Natgasoline would be excluded from the deal. So we're not in a position right now where it's a decision time on any of that, but the closing conditions are pretty clearly spelled out. That's one of the reasons, the lack of project financing was one of the reasons along with comments that we received from the SEC that in the last S-4 filing that we made, which you saw, was an assumption that Natgasoline was not part of the deal, with a footnote that said it could be included. And that reflects just the status of financing on that project.

Okay. Thank you for that. And a couple of updates, can you talk about Verdigris, some of the outages there? And also, there are a lot of trade general reports that perhaps as the new capacity at D'ville's come up, there's been some issues with that production. Are there any issues that you could speak of? Thanks.

We're very happy with the new plant at Donaldsonville. It's running well. And, look, I don't know how people drew that conclusion that the plant isn't running well. I think as Bert mentioned, we saw where pricing was trading on urea and thought, hey, at that level we're buyers not sellers. So, our decision to go in and grab a few barges had nothing to do with production problems. It was all about intrinsic value of the product versus where it was trading. So, Chris, I'll let you talk about it.

Yeah. And on the Verdigris, we have an ammonia plant. When we were doing the turnaround last year on the ammonia plant, we saw that we needed to replace some of the internals and catalysts. And that's the work that we're doing right now on that plant.

It's just some routine maintenance that we're taking care of.

Thank you.

Thank you. Our next question comes from Don Carson with Susquehanna. You may begin.

Yes. Thank you. Just question your forward order book, I noticed your customer advances were down almost 50% in dollar terms year-over-year. I assume your forward order book volumes were down even more. And Tony, you made references to some barges you were buying because of intrinsic value. It seems you've been more aggressive in buying out barges this year where you think the price is attractive. Is that an accurate assessment?

Well, I'd say, Don, that we have not really done that historically. And so, even if were we to buy one or two barges, that would be by definition more aggressive than we've been in the past, but we just looked at the numbers and said this price makes no sense. And we were – we have more than enough demand to accommodate us bringing on some barges. So we were in the mode of wanting to vacuum some of that up. I'll ask Bert to comment on the forward order book.

Couple of things on the forward order book. When – just on the overall price differentials for this spring compared to last spring, you've seen probably $100 per product change. So that's just on the aggregate dollar terms you mentioned. But having a forward order book or not having a forward book to me is a reflection of your view of the market. We are interested in selling forward. We have a plant and logistical assets that we need to maintain and move. So, there is an incentive, and matter of fact there is a requirement to make sure that that happens. However, that's also compared or contrasted against what the market is offering and the view that we think the market's going to improve. So, the incentive to have a forward order book in January and December just wasn't there. And, we have the capability to hold that product in inventory or change the production mix or export product. And so, we were able to maintain and move through those periods a lot better than I think we used to. And that's what you're seeing, to me, is reflected in that number rather than a desire to be out there to build the order book at lower prices.

So, most of this recent price fly up should be realized as you go forward in contrast to last year where you had locked in more forward business?

Yeah. I'll let you make that decision, but we think the spring is going to be positive.

Okay. Thank you.

Thank you. Our next question is from Matthew Korn with Barclays. You may begin.

Hey, good morning, everybody. Let me ask this, what right now are the most opportune export markets for you today, both in geography and product? Wondering if the disarray in Brazil has allowed there for any development for foundations of a UAN market down there. And then, just in terms of housekeeping, how much product that you actually send offshore this past quarter and this past year?

Yeah. So, when you look at the export markets, it's the marginal ton or the incremental ton for us at this point. We're in North America. It's an import market where we have our assets well placed. And when I say asset, that's the whole base production, logistics, terminals, pipelines, to serve the American or the North American farmer. So, we want to be active participants in this market and monetize our position here. And then the next step is looking at the export market. As we're adding this new capacity to be a 12 month, 365 day producer of these products, you need to be able to move things out and at times move them out in large quantities. So that's when we look to the export markets. We are active today in France, in Belgium, Argentina, Mexico, Brazil on UAN. We've opened up Columbia recently. And so when we're focused on products, today, it's predominantly a UAN play. And then, next step, we've had some ammonia exports. We've worked with various people in that market as well as destination consumers, but urea is coming. As we've brought up the new plant and as we move to the spring, we believe that we'll be active more in the world urea market. And so, I think you'll just see our export participation continue to grow and to be an integral part of our business.

The other thing I'd add to Bert's comment is that, particularly once we're through the OCI transaction and have that trading and distribution business as part of the fold, our desire to export will likely increase. And that's one of the reasons that Bert and his team have been really developing some of these other market opportunities for us, like UAN into Brazil and Argentina, giving us ready demand and outlets for that product as we go through the OCI deal.

Great. Thanks. That's helpful. Let me ask this then, everyone, of course, is focused on currency implications for price floor risk. But on a different angle, is there any immediate risk you see as a function of China's removal of their crop price support? Does that that put their domestic planting, their nitrogen demand at significant risk or threatening its ability to absorb as much of its own supply?

So, Matthew, just on the currency devaluation issue. You know that central bank stepped in recently and provided some exchange rate pegging that's actually more favorable than where we thought things were likely going to go. We thought the exchange could close to $7 and it's kind of pegged and the holding steady at $6.51 or $6.50. So, from that perspective, I think there is, at least as we see it today, a little bit less risk on the exchange rate side. But, Bert, why don't you go ahead and handle that?

Yeah, I think when you at what is going on with corn price supports and corn production, you've seen an interesting change over last 10 to 15 years as China has outsourced their soybean production to Brazil, Argentina, the United States and has continued to grow and with that grow their end demand for corn and wheat, and the stockpiles of corn aren't high. That has created some perverse incentives. And so you see sorghum and DDGs and things – and those substitute products coming in at a greater level into China. So I think with this release on pricing for corn, you're probably going to see – you could see maybe a lower level of planting, but, again, it's at a pretty high price today with that subsidy, and – but they also have a fairly low yield. So, several things are changing in China. The move to acquire Syngenta, which we believe with the seed technology and then germplasm associated with that, and the change possibly to GMO products in China, I think we have an evolving situation, coupled with the change in the economy, this currency devaluation, all of these things together. I think it's a little early to predict what that result will be to nitrogen, but we see each of these steps as positive opening steps and greater participation in the global market, which sustains the price of corn, soybeans and wheat going forward.

That's great. Thanks, gentlemen.

Thank you. Our next question is from Mark Connelly with CLSA. You may begin.

Thanks. Two easy questions. You mentioned the prospect of a stronger than normal back half of the year. I'm curious if you expect to carry out more inventory from spring, or whether the ramp in new capacity is enough to take care of that? And then the second question, I'm assuming you're still unhedged on the European business. And I wonder if you could talk about how your hedging strategy is going to evolve as you pick up OCI?

So, let me, I think, make one clarification and I'll ask Bert to pick up that one. But I think when we're talking about a stronger second half of the fertilizer year, as opposed to a stronger half of – the second half of the calendar year, because what happened was...

Okay.

... with the low level of application of ammonia in the fall or relatively lighter application, we still see total nitrogen aggregate demand in North America being roughly equivalent to where it was last year. So, corn acres are up a bit. Wheat acres we think are down a bit. Overall kind of the same amount of nitrogen, but with less going down in the fall, that means more has got to go down in the spring in order to get the same kind of yield. So, that's why we're pretty bullish here on the spring application season. I think everyone says the second half of the year, once you get past July 1, that's a complete reset and you start all over again.

Okay. Fair enough.

I don't know that we're taking a strong position on that one. Relative to Europe, yeah, we are completely unhedged both on the UK production as well as anything on the Continent. And our view historically has been that we hedge in order to take out price volatility typically associated with weather-related events. And recently here as we got into last year, we took some longer positions in North America. Obviously, those positions are upside down. And as we have kind of stepped back and evaluated our thinking on this, I think you'll see us head more towards our traditional approach, which is the hedging is really not try to lock-in any particular cost base over a long period of time, but it's really to take out seasonal volatility and possibly get rid of some basis risk.

Okay, very helpful. Thank you.

Thank you. Our next question is from Chris Parkinson with Credit Suisse. You may begin. Christopher S. Parkinson - Credit Suisse Securities (USA) LLC (Broker): Perfect. Thank you. Can you comment on your longer-term expectations regarding the respective cost curves for ammonia and nitrates versus urea due to the regional differences of feedstock costs, FX, et cetera? And then based on this, how do you perceive the average price spread in terms of nutrient tons? Do you believe parities will hold or even potentially expand, specifically in the potential event of further yuan depreciation? Thank you.

Yeah, Chris. Let me start off on kind of the long-term or how we view sort of mid-cycle pricing, which is the way that we kind of evaluate that is based on low cost gas regions bringing on new capacity, new capacity will continue to be added until the next marginal plants only reaches its kind of cost of capital return. And that's the price at which we say is kind of long-term mid-cycle prices. Even though feedstock costs have declined, as you've said, one of the things that's helpful in that equation is the fact that capital cost continues to increase. And the lowest cost gas region, right now, in terms of added new facilities is North America. And if you look at what the cost to bring new production on in North America, it is very high, as we know all too well. And the result of that is we have not seen a dramatic shift in our long-term view of where pricing has to be in order to support a healthy marketplace. It's moved a little bit, but not dramatically. And it's really the vast majority of the cost is in the ammonia-making step from a variable cost perspective. And so we believe that you'll continue to have to have sort of traditional increases in relative values the more upgrade you do because you've got to pay for new capital. Even though there's not very much variable cost there, you have to pay for the new capital to put in each new step in the upgrade process. And the functionality of UAN, as Bert was talking about earlier, is greater than urea or AN, or whatnot. So each step in the process has to return appropriate capital and also farmer gets more utility out of UAN, so…

Yeah, Chris, as we continue to do meetings and integration planning with our OCI counterparts, we continue to find opportunities and other synergies that were not necessarily previously known. I wouldn't say that all of those are in the tax front. In fact, most of them are not, they're mostly on the operational side, but there hasn't been any change in law at this point. And so our confidence level and projections are based on current law. So that remains as it was and that's why we say from an effective tax rate we're sort of in the low 20%s where we'll settle out we believe. Christopher S. Parkinson - Credit Suisse Securities (USA) LLC (Broker): Perfect. Thank you very much.

Thank you. Our next question is from P.J. Juvekar with Citi. You may begin.

Hey. Good morning, guys. It's Dan Jester on for P.J. So, if I hear Bert correctly, we missed some application in the fall, the winter buying season was pretty slow, and there's a risk of maybe an early spring. In the past that has been a scenario in which the supply chain has gotten pretty stressed. So can you talk if you're doing anything differently from a logistics standpoint this spring compared to the last couple of springs?

Dan. I'll let Bert answer that, but I wouldn't say it's a risk of an early spring. I'd say that's nothing but positive news, if, In fact, we start moving product here earlier than normal. But, Bert, go ahead.

So we look at a number of scenarios, and like any company would be doing scenario planning and looking at our asset capability and meet the customer demand, staying in contact with our customers, what they think they're going to see. And so I do believe you will have a stressed system. That being said, we have set up with our barge service provider ample service and what will be coming out of the plant, mostly Donaldsonville on barge, and utilizing our terminals that are served from the pipeline, as well as by barges, that being ammonia, and we are well positioned for that, and then it's UAN. And so when you look at probably in our early release on barges for ice lock, getting up into the upper Midwest to our furthest northern most point in Minneapolis, we think we'll be well supplied, well positioned. And as you see the weakening in the oil and the coal markets on rail, we're getting a lot better service from our rail providers. And we have 5,000 to 6,000 railcars in our service, as well as extras if needed. And we're fully utilizing those assets to get product in position.

The other thing I would add to Bert's comments, Dan, is that, given our broad base of in-market production and all the different major rail lines that we're on, plus all of our storage in different locations, we are sort of really able to deal with supply chain stress and disruptions on any of the rivers or rail systems, I think, better than most people because of the diversity of our asset base and our mix. And so, in a lot of cases, when those discontinuities or stress points happen, it benefits us disproportionately compared to other people. So, we're not afraid of it necessarily. It oftentimes brings some benefit to us.

Okay. That's really helpful. Thanks. And then just quickly on Trinidad gas curtailments have been going on there for several years now. So, is there something that changed your view about the outlook for Trinidad that forced the impairments this quarter? Thanks.

Yeah, I think a couple of things, Dan. As you know, most of the Trinidadian base gas contracts are indexed off of the underlying product. So in our case for our one plant joint venture indexed off of ammonia pricing. Some of them are off of methanol price; some of them are off of ammonia price and so forth. And so what's happened is as product pricing has come down, that means the gas price into the Point Lisas has stayed has also correspondingly come down. And it means there's less money going to NGC, National Gas Company. It's in the situation where at the price that's currently being paid for the gas that's below what we believe replacement cost of gas in Trinidad is. And so one of things that is different today than maybe a year or two ago was we believe that curtailments may have been more temporary in the past and that new production was coming online. As we sit here today, gas price doesn't justify the new investment needed to bring on additional production. And at the lower product pricing in the marketplace, you can't make up for the loss production that we're losing. So it's that combination of factors that's really led us to take the impairment.

Thank you so much.

Thank you. Our next question is from Andrew Wong with RBC. You may begin.

Hey, thank you. Good morning. So regarding the share repurchases, I mean, I know they're on hold because of the OCI Transaction, how quickly can you resume repurchases after the transaction is complete? I know there's blackout periods and stuff like that. So if you can just walk us through some of that thinking? And then, what sort of magnitude can we expect for this year?

Yeah. So I would say, Andrew, we are focused right now on getting through close. And as part of that process, of course, we're evaluating and updating our capital position. We believe, as I said earlier, that there's a lot of things that are really wind in our sales. So a combination of the CHS venture commencing and getting that cash in the door, and the benefits that we're going to be receiving as a result of bonus depreciation, means that we've got a lot of liquidity. And given where the share price is trading, of course, we're very anxious to start deploying that. But we need to get through the close first and then we'll make an appropriate announcement. It's going to require authorization by the new Board of Directors of the newly constituted company before we're able to do anything, but I'm as anxious as anyone to get after it as soon as possible.

Okay. And then maybe just switching to something else, the Chinese nitrogen production. I know that there's recently been some reports that they have lower operating rates. Do you have a sense of whether these are more temporary type curtailments or are we talking about more permanent type shutdowns?

I mean I think our view is, there has been a lot of new capacity coming on in China and the excess overhang is capacity that the world doesn't really need, but these reduction in operating rates tend to be more offset – permanent offset against some of the new capacity that's come on. We don't think that it makes sense for that – all of that production to be running where it was. And so, when you see operating rates come back, I think it's not because they're producing – going to be producing more, it's because some of those plants are going to be permanently shut down and taken kind of off of the capacity curve.

Okay. Thank you.

Thank you. Ladies and gentlemen, that is all the time we have for your questions for today. I'd like to turn the call back to Dan Aldridge for closing remarks.

That concludes our call today. I'm available for any follow-on questions. Thank you for your time and interest everybody.

Ladies and gentlemen, this concludes today's conference. Thank you for your participation. Have a wonderful day.
