WESTLAKE CORPORATION

WESTLAKE CORPORATION sits at the top of a group of 5 entities that report it as their consolidating parent, from its registered address in WILMINGTON, United States.

The LEI has been on record for 14 years, since 6 Jun 2012. That is about 7 years earlier than the median LEI in United States, which dates from 2019 — an early adopter by local standards.

The next annual re-validation is due 20 Jun 2027, 218 days from now.

The record has not changed since we began archiving it on 6 Jul 2026. Any future change to name, status, address, ownership or renewal date will be captured here, because GLEIF publishes only the current state and superseded values are otherwise lost.

The LEI is issued and maintained by Bloomberg Finance L.P., one of the Local Operating Units accredited by GLEIF.

Beyond the LEI, 14 ISINs are mapped to this entity in the GLEIF cross-reference files.

No direct accounting-consolidating parent is reported, because no controlling person is known. GLEIF requires this to be stated explicitly rather than left blank, so the absence is itself a data point.

No ultimate accounting-consolidating parent is reported, because no controlling person is known. GLEIF requires this to be stated explicitly rather than left blank, so the absence is itself a data point.

The LEI registration is issued, and the entity status (active) records whether the legal entity itself still exists. The two are independent: an LEI can lapse while the company trades on, and it can stay issued after the company has been dissolved.
