CENTURY ALUMINUM CO (CENX) as-reported value updates

Descriptive filing record — not investment advice. This page compares two SEC XBRL-filed values for the same fiscal period. It does not state why the values differ and is not a rating, score, or recommendation. See Disclaimer.

Reported values for the same fiscal period can differ between filings for many routine reasons: re-presentation for discontinued operations, adoption of new accounting standards, reclassifications, changes in rounding precision, and amendments. This ledger records that the filed values differ; it does not and cannot determine why. Both filings are linked below so the reader can consult the source.

Rows publish only when the later filed value differs by at least 1.0% and at least $1,000,000, after dropping differences that match under the capped trailing-zero precision rule. The delta percent is delta divided by the larger absolute filed value. Values are annual standardized facts only; metrics whose differences fall below those thresholds or match the capped precision rule are not published as rows.
