Every figure is extracted from WESTLAKE CORP’s annual reports as filed with the SEC (XBRL company facts) — no third-party estimates. Fiscal years are labeled by period end; filers occasionally re-tag concepts, so a sparse cell means the company didn’t report that concept for that year. Free cash flow = operating cash flow − capital expenditures.
