Accounting Policies [Abstract]
Recently Issued and Adopted Accounting Pronouncements and Regulatory Items	Recently Issued and Adopted Accounting Pronouncements and Regulatory Items New accounting guidance and regulatory items On November 4, 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures, to require disaggregation of certain expense captions into specified categories in disclosures within the notes of the financial statements. The standard is effective for FMC beginning with the Form 10-K for the year ended December 31, 2027, and early adoption is permitted. The guidance is required to be applied prospectively and amendments in the ASU may be applied prospectively or retrospectively. We are currently evaluating the impacts this standard will have on our disclosures. On December 14, 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Changes to the Disclosure Requirements for Income Taxes, to improve the transparency and decision usefulness of income tax disclosures. The standard requires companies to disclose a tabular effective rate reconciliation with certain reconciling items broken out by nature and/or jurisdiction as well as more robust disclosures of income taxes paid, specifically broken out between federal, state and foreign. The standard can be applied prospectively or retrospectively and early adoption is permitted. The ASU is effective for FMC beginning with the Form 10-K for the year ended December 31, 2025. We are currently evaluating the impacts this standard will have on our income tax disclosures.

The entire disclosure for change in accounting principle. Includes, but is not limited to, nature, reason, and method of adopting amendment to accounting standards or other change in accounting principle.
