This Amendment No. 1 (“Amendment No. 1”) to Schedule 13D relates to common units representing limited partner interests (the “Common Units”) of Westlake Chemical Partners LP, a Delaware limited partnership (the “Issuer”), and amends the initial statement on Schedule 13D filed on October 26, 2017 (the “Original Schedule 13D”, and as amended, the “Schedule 13D”). Capitalized terms used but not defined in this Amendment No. 1 shall have the same meanings ascribed to them in the Schedule 13D.

Item 3. Source and Amount of Funds or Other Consideration

Item 3 of the Schedule 13D is hereby supplemented by adding the following:

The aggregate number and percentage of Common Units beneficially owned by each Reporting Person and, for each Reporting Person, the number of Common Units as to which there is sole power to vote or to direct the vote, shared power to vote or to direct the vote, sole power to dispose or to direct the disposition, or shared power to dispose or to direct the disposition are set forth on rows 7 through 11 and row 13 of the cover pages of this Schedule 13D and are incorporated herein by reference.

None of the Reporting Persons has any pecuniary interest in the securities reported as beneficially owned by HFA in this Schedule 13D, as such term is used for purposes of Section 16 of the Exchange Act. Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that any of the Reporting Persons is the beneficial owner of the securities referred to herein for purposes of Section 13(d) or Section 16 of the Exchange Act or for any other purpose.


Item 5(c) of the Schedule 13D is hereby amended and restated as follows:

The Derivative Agreements provide such holder with economic results that are comparable to the economic results of ownership but do not provide it with the power to vote or direct the voting or dispose of or direct the disposition of the Common Units that are the subject of the Derivative Agreements (such units, the “Subject Units”). The Reporting Persons disclaim beneficial ownership in the Subject Units. The counterparties to the Derivative Agreements are unaffiliated third party financial institutions.
