Item 8.01 Other Events. Citigroup Inc. (Citi) is filing this Current Report on Form 8-K, consistent with ASC 280 Segment Reporting, to conform its Historical Consolidated Financial Statements and Notes, and Management's Discussion and Analysis of Financial Condition and Results of Operations and other Form 10-K sections (see exhibit 99.1 attached hereto) to reflect changes in Citi's reportable segments from those contained in Citi's Annual Report on Form 10-K for the year ended December 31, 2021 (2021 Annual Report on Form 10-K) filed with the U.S. Securities and Exchange Commission (SEC) on February 28, 2022.

As of December 31, 2021, Citi was managed pursuant to two operating segments-Institutional Clients Group and Global Consumer Banking-with the remaining operations in Corporate/Other. Citi conformed Exhibit 99.1 to reflect its new financial reporting structure as of the first quarter of 2022, including its three operating segments-Institutional Clients Group, Personal Banking and Wealth Management and Legacy Franchises, with the remaining operations in Corporate/Other. On May 9, 2022, Citi filed its Quarterly Report on Form 10-Q for the quarter ended March 31, 2022 (First Quarter 2022 Form 10-Q) with the SEC reflecting this new financial reporting structure.

The information included in this Current Report on Form 8-K reflects changes to the disclosures related to Citi's revised segment results (including related reclassifications between consumer and corporate loans, and related allowance for credit losses) and does not revise Citi's consolidated financial condition or results of operations nor does it reflect any events occurring after the filing of the 2021 Annual Report on Form 10-K. The Historical Consolidated Financial Statements and Notes will serve as the historical consolidated financial statements and notes of Citi for existing and future filings made pursuant to the Securities Act of 1933, as amended, until Citi files its Annual Report on Form 10-K for the year ended December 31, 2022. This Current Report on Form 8-K, including the information contained in Exhibit 99.1, should be read in conjunction with Citi's 2021 Annual Report on Form 10-K and the First Quarter 2022 Form 10-Q.
