Westlake Chemical Partners LP (NYSE: WLKP) (the "Partnership") today reported net income attributable to the Partnership of $10.9 million, or $0.39 per limited partner unit, for the three months ended December 31, 2016, an increase of $0.1 million compared to fourth quarter 2015 net income attributable to the Partnership of $10.8 million. The increase in net income attributable to the Partnership as compared to the prior-year period was primarily due to higher production volumes at Westlake Chemical OpCo LP’s (“OpCo”) Petro 1 facility in Lake Charles, Louisiana resulting from the 250 million pound ethylene expansion completed in July 2016. For the three months ended December 31, 2016, cash flow from operations was $110.4 million, a decrease of $10.9 million compared to fourth quarter 2015 cash flow from operations of $121.3 million. This decrease in cash flow from operations was due to an increase in working capital, partially offset by increased production. For the three months ended December 31, 2016, MLP distributable cash flow was $11.8 million, an increase of $1.7 million compared to fourth quarter 2015 MLP distributable cash flow of $10.1 million. The increase in MLP distributable cash flow as compared to the prior-year period was primarily due to higher production volumes at Petro 1 resulting from the 250 million pound ethylene expansion project.

The fourth quarter 2016 net income attributable to the Partnership of $10.9 million, or $0.39 per limited partner unit, increased by $2.2 million from third quarter 2016 net income attributable to the Partnership of $8.7 million, or $0.32 per limited partner unit. Fourth quarter 2016 cash flow from operations of $110.4 million increased by $118.3 million compared to third quarter 2016 cash flow from operations of $(7.9) million. Fourth quarter 2016 MLP distributable cash flow of $11.8 million increased by $5.0 million compared to third quarter 2016 MLP distributable cash flow of $6.8 million. The increase in net income attributable to the Partnership, cash flow from operations and MLP distributable cash flow as compared to the prior quarter was primarily due to higher production volumes, lower capital expenditures at Petro 1 and a decrease in working capital following the completion of the 250 million pound ethylene expansion at Petro 1 in July 2016.

For the full year 2016, net income attributable to the Partnership of $40.9 million, or $1.50 per limited partner unit, increased by $1.1 million when compared to full year 2015 net income attributable to the Partnership of $39.8 million, or $1.47 per unit. Cash flow from operations of $287.7 million for 2016 decreased by $164.7 million when compared to cash flow from operations of $452.4 million for 2015 due to lower production at Petro 1 and an unplanned outage at OpCo’s facility in Calvert City, Kentucky, increases in working capital and turnaround expenditures at Petro 1. MLP distributable cash flow of $32.4 million for 2016 decreased by $5.3 million, when compared to 2015 MLP distributable cash flow of $37.7 million, primarily as a result of lower production due to the Petro 1 expansion project as well as the unplanned outage at Calvert City in June and July 2016.

On January 19, 2017, the Internal Revenue Service (“IRS”) and U.S. Department of Treasury (“Treasury”) issued final regulations under section 7704(d)(1)(E) of the Internal Revenue Code (the “Code”) relating to qualifying income from the processing, refining and transportation of minerals or natural resources, which allows a business to be treated as a partnership for U.S. federal tax purposes. Our sponsor, Westlake Chemical Corporation (“Westlake”), previously requested and received a favorable private letter ruling from the IRS prior to the formation and initial public offering of the Partnership to the effect that the production, transportation, storage and marketing of ethylene constitutes “qualifying income” within the meaning of section 7704(d)(1)(E). The final regulations issued by the IRS and Treasury uphold Westlake’s private letter ruling and holds that the Partnership’s activities constitute “qualifying income.”

On January 27, 2017, the Board of Directors of Westlake Chemical Partners GP LLC, the general partner of the Partnership, announced a quarterly distribution for the fourth quarter of 2016 of $0.3450 per limited partner unit to be payable on February 22, 2017 to unit holders of record as of February 7, 2017. The fourth quarter 2016 distribution increased 12.0% compared to the fourth quarter 2015 distribution and 2.89% compared to the third quarter 2016 distribution. MLP distributable cash flow provided coverage of 1.26x the declared distributions for the fourth quarter of 2016. The increase in cash distributions is in line with the Partnership's targeted low double-digit distribution growth.

OpCo's sales agreement with Westlake is designed to provide for stable and predictable cash flows. The sales agreement provides that 95% of OpCo's ethylene production is sold to Westlake for a cash margin of $0.10 per pound, net of operating costs, maintenance capital expenditures and reserves for future turnaround expenditures.

“This quarter we achieved record production for the first full quarter following the 250 million pound expansion of the Petro 1 facility, which was completed in July 2016. This quarter’s performance highlights the strength of the Partnership as we saw the strongest quarterly coverage ratio since our IPO in August of 2014 while continuing to increase our distributions to unit holders,” said Albert Chao, President and Chief Executive Officer. Regarding the IRS’s final regulations regarding qualifying income, Chao stated “We appreciate the thorough process taken by the IRS and Treasury Department to reach their final decision and are pleased that the final regulations reconfirm and properly recognize these industry practices and remove uncertainty that our activities will continue to generate qualifying income under the Code.”

The statements in this release and the related teleconference relating to matters that are not historical facts are forward-looking statements. These forward-looking statements are subject to significant risks and uncertainties. Actual results could differ materially, based on factors including, but not limited to, 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 price and availability of feedstocks; changes in prevailing economic conditions; actions of Westlake Chemical Corporation; actions of third parties; inclement or hazardous weather conditions, including flooding, and the physical impacts of climate change; environmental hazards; changes in laws and regulations (or the interpretation thereof); inability to acquire or maintain necessary permits; inability to obtain necessary production equipment or replacement parts; technical difficulties or failures; labor disputes; difficulty collecting receivables; inability of our customers to take delivery; fires, explosions or other industrial accidents; our ability to borrow funds and access capital markets; and other risk factors. For more detailed information about the factors that could cause actual results to differ materially, please refer to the Partnership's Annual Report on Form 10-K for the year ended December 31, 2015, which was filed with the SEC in March 2016.

This release is intended to be a qualified notice under Treasury Regulation Section 1.1446-4(b). Brokers and nominees should treat one hundred percent (100.0%) of the Partnership's distributions to non-U.S. investors as being attributable to income that is effectively connected with a United States trade or business. Accordingly, the Partnership's distributions to non-U.S. investors are subject to federal income tax withholding at the highest applicable effective tax rate.

Use of Non-GAAP Financial Measures

This release makes reference to certain “non-GAAP” financial measures, such as MLP distributable cash flow, as defined in Regulation G of the U.S. Securities Exchange Act of 1934, as amended. We report our financial results in accordance with U.S. generally accepted accounting principles ("GAAP"), but believe that certain non-GAAP financial measures, such as MLP distributable cash flow and EBITDA, provide useful supplemental information to investors regarding the underlying business trends and performance of our ongoing operations and are useful for period-over-period comparisons of such operations. These non-GAAP financial measures should be considered as a supplement to, and not as a substitute for, or superior to, the financial measures prepared in accordance with GAAP. A reconciliation of MLP distributable cash flow and EBITDA to net income and net cash provided by operating activities can be found in the financial schedules at the end of this release. We define distributable cash flow as net income plus depreciation and amortization, less contributions from turnaround reserves and maintenance capital expenditures. We define MLP distributable cash flow as distributable cash flow less distributable cash flow attributable to Westlake's noncontrolling interest in OpCo and distributions attributable to incentive distribution rights holder. MLP distributable cash flow does not reflect changes in working capital balances. We define EBITDA as net income before interest expense, income taxes, depreciation and amortization. Because MLP distributable cash flow and EBITDA may be defined differently by other companies in our industry, our definition of MLP distributable cash flow and EBITDA may not be comparable to similarly titled measures of other companies.
