EQUITY RESIDENTIAL New Standards Disclosure

Recent Accounting Pronouncements

In December 2025, the Financial Accounting Standards Board (“FASB”) issued an amendment to the interim reporting standards which is intended to improve the navigability of the required interim reporting disclosures and clarify when that guidance is applicable. The update provides a comprehensive list of interim disclosures required under accounting principles generally accepted in the United States ("GAAP") and incorporates a disclosure principle that requires disclosures at interim periods when an event or change that has a material effect on an entity has occurred since the previous year end. The standard will be effective for interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted, and may be applied either prospectively or retrospectively. The Company is currently evaluating the impact of the new rules on its disclosures.

In November 2024, the FASB issued a new standard on disaggregation of income statement expenses, which requires an entity to disclose, on an annual and interim basis, disaggregated information about certain income statement expense line items in a tabular format in the notes to the financial statements. The standard will be effective for annual reporting periods beginning after December 15, 2026 and for interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted, and may be applied either prospectively or retrospectively. The Company is currently evaluating the impact of the new rules on its disclosures.

In December 2023, the FASB issued an amendment to the income tax standards which requires disclosure enhancements and further transparency to certain income tax disclosures, most notably the tax rate reconciliation and income taxes paid. The Company adopted the standard when effective for annual periods beginning January 1, 2025 on a prospective basis. Due to the nature of the Company's operations and the immaterial amount of income taxes incurred/paid due to its status as a REIT, adoption of the standard had no impact on its disclosures. See the Income and Other Taxes section above for additional discussion.

In November 2023, the FASB issued an amendment to the segment reporting standards which requires disclosure for each reportable segment, on an interim and annual basis, of the significant expense categories and amounts that are regularly provided to the chief operating decision maker and included in each reported measure of a segment’s profit or loss. Additionally, it requires disclosure of the title and position of the individual or the name of the group or committee identified as the chief operating decision maker. The Company adopted the standard when effective for annual periods beginning January 1, 2024 and interim periods beginning January 1, 2025 on a retrospective basis. See Note 16 for further discussion.

In March 2020, the FASB issued an amendment to the reference rate reform standard which provides the option for a limited period of time to ease the potential burden in accounting for, or recognizing the effects of, reference rate reform on contract modifications and hedge accounting. The new standard was effective for the Company upon issuance and elections could be made through December 31, 2024. The Company elected to apply the hedge accounting expedients and application of these expedients preserves the presentation of derivatives consistent with past presentation.
