Item 8.01. Other Events.

Repayment of Revolving Credit Facility Borrowings

As previously reported, on March 20, 2020, out of an abundance of caution, Westlake Chemical Corporation (the “Company”) borrowed $1 billion under its $1 billion revolving credit facility that is scheduled to mature on July 24, 2023 (the “Credit Agreement”) to ensure ample financial flexibility in light of the uncertainty in the global financial markets caused by the Coronavirus pandemic. The Company indicated at that time its expectation that it would repay these borrowings when the uncertainty in the global financial markets sufficiently subsided.

The Company believes the various initiatives of the Federal Reserve Board and the U. S. Federal Government enacted after the Coronavirus pandemic outbreak in the United States have stabilized the financial markets, and the gradual opening of economic activities in the United States and abroad have also improved economic conditions.  Thus, on June 4, 2020, the Company fully repaid the $1 billion of borrowings under the Credit Agreement and, as a result, has no current borrowings outstanding under its revolving credit facility.  The $1 billion revolving credit facility remains available to the Company for future borrowings.

The material terms of the Credit Agreement are described in the section “Liquidity and Capital Resources—Debt—Credit Agreement” in Part II, Item 7 of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2019 filed with the Securities and Exchange Commission on February 19, 2020 (the “2019 Form 10-K”). A copy of the Credit Agreement is an exhibit to the 2019 Form 10-K.
