Good morning, ladies and gentlemen. Thank you for standing by. Welcome to the Westlake Chemical Partners fourth quarter and full year 2017 earnings conference call. During the presentation, all participants will be in a listen-only mode. After the speakers' remarks, you will be invited to participate in a question-and-answer session. As a reminder, ladies and gentlemen, this conference is being recorded today, February 20, 2018. I would now like to turn the conference over to today's host, Jeff Holy, Westlake Chemical Partners' Vice President and Treasurer. Sir, you may begin.

Thank you Sabrina. Good morning everyone and welcome to the Westlake Chemical Partners' fourth quarter and full year 2017 conference call. I am joined today by Albert Chao, our President and CEO, Steve Bender, our Senior Vice President and Chief Financial Officer and other members of our management team. The conference call will begin with Albert, who will open with a few comments regarding Westlake Chemical Partners' performance in the fourth quarter and full year as well as the current outlook on our performance and opportunities. Steve will then provide a more detailed look at our financial and operating results. Finally, Albert will add a few concluding comments and then we will open up the call to questions. During this call, we refer to ourselves as Westlake Partners or the Partnership. References to Westlake or Westlake Chemical refer to our parent company, Westlake Chemical Corporation and references to OpCo refer to Westlake Chemical OpCo LP, a subsidiary of Westlake Chemical and the Partnership which owns certain olefins assets. Today, management is going to discuss certain topics that will contain forward-looking information that is based on management's beliefs as well as assumptions made by and information currently available to management. These forward-looking statements suggest predictions or expectations and thus are subject to risks or uncertainties. Actual results could differ materially based upon many factors, including operating difficulties, the volume of ethylene that we are able to sell, the price at which we are able to sell ethylene, changes in the prevailing economic conditions, actual and proposed governmental regulatory actions, competitive products and pricing pressures, our ability to borrow funds and access capital markets and other risk factors discussed in our SEC filings. This morning, Westlake Partners issued a press release with details of our fourth quarter and full year financial and operating results.

Thank you Jeff. Good morning ladies and gentlemen and thank you for joining us to discuss our fourth quarter and full year 2017 results. In this morning's press release, we reported consolidated net income including OpCo's earnings of $98 million for the fourth quarter of 2017. Westlake Partners' fourth quarter net income was a record $16 million. For the full year 2017, net income including OpCo's earnings was $353 million. Partners' 2017 net income was a record $49 million. 2017 was a milestone year for Partners as we completed our first equity offering since our IPO in August 2014. This offering was completed in conjunction with our second dropdown transaction with MLP producing an additional 5% interest in OpCo. This transaction was effective July 1 as we continued our path of growing distributions to our unitholders. On January 29, 2018, we announced distributions of $0.3864 per unit with respect to the fourth quarter of 2017. This is a 2.9% increase from the third quarter 2017 distribution and a 12% increase from the fourth quarter 2016 distribution. This is the twelfth consecutive quarterly increase in distributions to our unitholders since our IPO. For the fourth quarter 2017, MLP distributable cash flow provided coverage of 1.35 times to declared distributions and we finished the year with coverage of 1.24 times to declared distributions for the full year 2017 I would now like to turn our call over to Steve to provide more detail on the financial and operating results for the fourth quarter. Steve?

Thank you Albert and good morning everyone. In this morning's press release, we reported consolidated net income including OpCo's earnings of $98 million on consolidated sales of $309 million for the fourth quarter 2017. Westlake Partners' fourth quarter net income was a record $16 million, or $0.46 per limited partner unit. We also reported record MLP distributable cash flow of $17 million for the fourth quarter. Fourth quarter net income for Westlake Partners of $16 million increased by $5 million or $0.07 per limited partner unit compared to fourth quarter 2016 Partnership net income of $11 million. The increase in net income was primarily due to the 5% increased ownership interest in OpCo as a result of the dropdown transaction that was effective July 1, 2017 and increased production at OpCo's Petro 1 facility in Lake Charles, Louisiana and Calvert City, Kentucky facility. This increase in production includes the added capacity from the 100 million pound ethylene expansion in Calvert City, which was completed in April 2017. MLP distributable cash flow of $17 million for the fourth quarter 2017 was $5 million higher than the fourth quarter of 2016 MLP distributable cash flow of $12 million. This increase in MLP distributable cash flow was primarily due to the increased ownership interest in OpCo, higher production and lower maintenance cost. The Partnership's fourth quarter 2017 net income of $16 million was $3 million higher than third quarter 2017 net income of $13 million. MLP distributable cash flow of $17 million was $2 million higher than third quarter MLP distributable cash flow of $15 million. The increase in net income and MLP distributable cash flow [indiscernible] fourth quarter of 2017 was primarily due to higher production at all of OpCo's facilities compared to the prior quarter. For the full year 2017, net…

Thank you Steve. The stable fee-based cash flow generated by the fixed margin take or pay ethylene sales agreement with Westlake Chemical forms the foundation for us to deliver long-term growth in distributions to our unitholders. We continue to evaluate all the levers of growth available to us to increase our earnings and cash flows, including organic expansions of our current ethylene facilities, periodic dropdowns of OpCo into the MLP, acquisitions of other qualified income streams, either directly or jointly with our sponsor Westlake Chemical and negotiating a higher fixed margin in our ethylene sales agreement with Westlake. Looking forward, we plan to continue to deliver low double-digit growth in distributions to our unitholders. The recent ethylene expansions in Lake Charles and Calvert City have added to our production capacity to fund these distributions. Our most recent dropdown in the third quarter of 2017 highlights the ability of these accretive transactions with OpCo to fund earnings and distribution growth. OpCo has a large dropdown capacity and we plan to increase our ownership of OpCo in the future. The new Gulf Coast ethylene cracking joint venture that Westlake and Lotte are constructing could be considered an opportunity for acquisition upon its completion in 2019. Finally, we will evaluate all four levers of growth to optimize our earnings and cash flow and maximize value for all stakeholders. Thank you very much for listening to our fourth quarter and full year 2017 earnings call this morning. Now I will turn the call back over to Jeff.

Thank you Albert. Before we begin taking questions, I would like to remind you that a replay of this teleconference will be available starting two hours after we conclude the call. We will provide that number again at the end of the call. Sabrina, we will now take questions.

[Operator Instructions]. The first question will come from the line of Steve Byrne with Bank of America. Your line is now open.

Yes. So I just wanted to ask about your capacity expansions of your ethylene crackers at Lake Charles and Calvert City in recent years. Are there rate limiting operations there that are either in the furnace or in the downstream recovery that you have excess capacity there that to further debottleneck wouldn't require the entire facility be expanded? Or is it possible that it is just portions of those plants?

Well, certainly our engineers constantly look at opportunities to further debottleneck and get more productions. But I will say that a large part of the large capacity expansions has been completed but every day our people are working to improve the operations.

And with respect to the joint venture with Lotte Chem, if you were to commit to that project earlier than later, are the economics any different?

No, Steve. The economics are at producer economics. And so if we elect to increase our ownership percentage, the investment or any incremental investment beyond our 10% is simply just the total installed cost to construct the facility and the reimbursement at a single-digit interest carry cost while Lotte is financing this during construction.

Okay. Thank you.

You are welcome.

Thank you. And the next question will come from the line of Duffy Fischer with Barclays. Your line is now open.

Hi guys. It's Mike Leithead, on for Duffy.

Good morning.

Good morning. With the Westlake PVC/VCM announcements, you will be consuming more ethylene internally now. So does that change at all how you guys think about the 5% spot ethylene sales in the current agreement? And does that increase the likelihood of the Lotte [indiscernible] being added to the current structure?

It does not change our thinking around the 5% being sold into the market. We certainly still think that's important for a variety of reasons. And as it relates to the Lotte investment, we will continue to assess the return potential that has to Westlake Chemical industry and should they elect to increase their ownership from the 10% to a percentage higher than that, certainly it increases the appetite for OpCo to think about buying even a greater share potentially negotiating that with Westlake, our sponsor, as they think about and make whatever decision they choose to make.

Got it. Okay. And then you recently completed a nice dropdowns in the third quarter. How should we think about the cadence of dropdowns this year and beyond to 2019?

As we think about continuing our growth strategy, as you can see we have a very large amount of inventory to continue to dropdown, we certainly can also think in terms of the other three levers that Albert made reference to which is the margin arrangement today currently at $0.10 that could be increased over time, simply part of the negotiation, debottleneck opportunities in the crackers that we have and any future cracker that we might own as well as the opportunity to grow the business over time through acquisitions. So when we think about the cadence, the answer really is, it is a function as long as were seen the value for the growth that is being offered here, we will continue that cadence. And that could continue us into 2018 or early 2019. This dropdown that we concluded in the third quarter of 2017 provide us good runway in 2018. And so long as we are seeing the value trade-off with investors, we will continue that cadence that is appropriate for the value in return for that growth.

Great. Thanks guys.

You are welcome.

You are welcome.

Thank you. And the next question will come from the line of Matthew Blair with Tudor, Pickering, Holt & Co. Your line is now open.

Hi. Good morning, Albert and Steve.

Good morning.

Good morning Matthew.

I believe production was 925 million pounds in Q3. Steve, do you have that number for Q4? And is there any reason to believe that Q1 2018 production would be significantly different than Q4 2017 levels?

So Matthew, our production in the in the fourth quarter was just slightly under 970 million pounds. And certainly, given the demand that our sponsor has for ethylene, we want to continue to run these units as strongly as we can. Our current plan for turnaround does not include 2018. The thinking currently is for the next turnaround to be in 2019. So absent any unusual events in operations, I would expect the plants continue to operate as strongly and as well as they have been most recently.

Great. And then on the balance sheet, could you just clarify this line item here, this receivable under investment management agreement. So did you consider that $137 million to be WLKP cash? If you could just clarify that, that would be helpful.

Yes, it is cash and is freely available at really no notice. They simply just need to call on that and it's simply just an investment mechanism for the Partnership, just as if they were investing with anybody else and they can call on that cash at a moment's notice.

Great. Thank you very much.

You are welcome.

[Operator Instructions]. And the next question comes from the line of Robert Balsamo with B. Riley FBR. Your line is now open.

Hi. How is it going, guys?

Good morning.

Good morning.

Just a couple of housekeeping items. The first, could you clarify the debt level at the Partnership, just I guess the revolver current level?

Yes. So at the Partnership, it's $254 million and at OpCo it's $220 million.

Great. And regarding the Lotte expand the Lotte project, is there any change to the status on that? Is it still on track to 2019? Any clarity around timing? If there is no change at all?

It has not changed and it still is expected to start up in the first half of 2019.

First half of 2019. All right. That's it for me. Thanks a lot. Congrats on a nice stable quarter.

Thank you very much.

Thank you.

Thank you. And we do have a follow-up question from the line of Matthew Blair with Tudor, Pickering, Holt & Co. Your line is now open.

Yes. Just one more. Thanks. I guess just in terms of valuation here, so you have maintained your 12% distribution growth rate since inception, despite what's been a pretty volatile MLP market. You are sitting at 1.35 coverage. You have a huge backlog of droppable assets. Your yield is all the way up to 6.9%. Are you happy with that? Or do you think you are getting paid for your 12% growth rate? How do you assess the valuation of the MLP here?

You know Matthew, that's an excellent point. And the answer is no, I am not happy with that. I believe that we are not getting the full valuation that we merit. And that's why when I was asked earlier by one of the questioners about our growth plan for 2018, I made the comment that our growth in distribution is predicated on the assumption that we will get value back. And if we don't, we will have to think about that growth plan.

Great. Thank you.

You are welcome.

Thank you. At this time, the question-and-answer session has ended. Are there any closing remarks?

Thank you again for participating in today's call. We hope you will join us for our next conference call to discuss our first quarter 2018 results.
