Accounting Policies [Abstract]
BASIS OF PRESENTATION, UPDATED ACCOUNTING POLICIES AND ACCOUNTING CHANGES	BASIS OF PRESENTATION, UPDATED ACCOUNTING POLICIES AND ACCOUNTING CHANGES Basis of Presentation The accompanying unaudited Consolidated Financial Statements as of March 31, 2022 and for the three-month periods ended March 31, 2022 and 2021 include the accounts of Citigroup Inc. and its consolidated subsidiaries. In the opinion of management, all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation have been reflected. The accompanying unaudited Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and related notes included in Citigroup’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021 (2021 Form 10-K). Certain financial information that is normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP), but is not required for interim reporting purposes, has been condensed or omitted. Management must make estimates and assumptions that affect the Consolidated Financial Statements and the related footnote disclosures. While management uses its best judgment, actual results could differ from those estimates. As noted above, the Notes to these Consolidated Financial Statements are unaudited. Throughout these Notes, “Citigroup,” “Citi” and “the Company” refer to Citigroup Inc. and its consolidated subsidiaries. Certain reclassifications and updates have been made to the prior periods’ financial statements and notes to conform to the current period’s presentation. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES See Note 1 to the Consolidated Financial Statements in Citigroup’s 2021 Form 10-K for a summary of all of Citigroup’s significant accounting policies. ACCOUNTING CHANGES Accounting for Deposit Insurance Expenses During the fourth quarter of 2021, Citi changed its presentation of accounting for deposit insurance costs paid to the Federal Deposit Insurance Corporation (FDIC) and similar foreign regulators. These costs were previously presented within Interest expense and, as a result of this change, are now presented within Other operating expenses . Citi concluded that this presentation was preferable in Citi’s circumstances, as it better reflected the nature of these deposit insurance costs in that these costs do not directly represent interest payments to creditors, but are similar in nature to other payments to regulatory agencies that are accounted for as operating expenses. This change in income statement presentation represents a “change in accounting principle” under ASC Topic 250, Accounting Changes and Error Corrections , with retrospective application to the earliest period presented. This change in accounting principle resulted in a reclassification of $340 million of deposit insurance expenses from Interest expense to Other operating expenses , for the quarter ended March 31, 2021. This change had no impact on Citi’s net income or the total deposit insurance expense incurred by Citi. FUTURE ACCOUNTING CHANGES Obligations to Safeguard Crypto-assets Held for Platform Users In March 2022, the SEC issued Staff Accounting Bulletin (SAB) No. 121, which expresses the views of the SEC staff regarding the accounting for obligations to safeguard crypto-assets an entity holds for platform users. Specifically, the guidance requires issuers that hold digital assets for their platform users to recognize a liability for their obligation to safeguard the digital assets held and a corresponding asset, measured initially and subsequently at fair value. The guidance is effective for interim and annual periods ending after June 15, 2022, with retrospective application to the beginning of the fiscal year, with early adoption permitted. Citi is currently assessing the application of SAB 121, but based on its current activity does not expect any impact to its results of operations as a result of adopting SAB 121. Fair Value Hedging—Portfolio Layer Method In March 2022, the FASB issued ASU No. 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method , intended to better align hedge accounting with an organization’s risk management strategies. Specifically, the guidance expands the current single-layer method to allow multiple hedge layers of a single closed portfolio of qualifying assets, which include both prepayable and non-prepayable assets. Upon the adoption of the guidance, entities may elect to reclassify securities held-to-maturity to the available-for-sale category as long as the reclassified securities are designated in a portfolio hedge. The guidance is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years with early adoption permitted. Citi is evaluating when to adopt the amendments in ASU 2022-01. Citi does not expect a material impact to its results of operations as a result of adopting the amendments. Troubled Debt Restructurings and Vintage Disclosures In March 2022, the FASB issued ASU No. 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures . The ASU eliminates the accounting guidance for troubled debt restructurings by creditors, enhances disclosure requirements for certain loan refinancings and restructurings by creditors and requires that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20. The guidance is effective beginning January 1, 2023 and early adoption is permitted. Citi is evaluating whether to early adopt and the effect that ASU 2022-02 will have on its Consolidated Financial Statements and related disclosures. Long-Duration Insurance Contracts In August 2018, the FASB issued ASU No. 2018-12, Financial Services—Insurance: Targeted Improvements to the Accounting for Long-Duration Contracts , which changes the existing recognition, measurement, presentation and disclosures for long-duration contracts issued by an insurance entity. Specifically, the guidance (i) improves the timeliness of recognizing changes in the liability for future policy benefits and prescribes the rate used to discount future cash flows for long-duration insurance contracts, (ii) simplifies and improves the accounting for certain market-based options or guarantees associated with deposit (or account balance) contracts, (iii) simplifies the amortization of deferred acquisition costs and (iv) introduces additional quantitative and qualitative disclosures. Citi has certain insurance subsidiaries, primarily in Mexico, that issue long-duration insurance contracts such as traditional life insurance policies and life-contingent annuity contracts that will be impacted by the requirements of ASU 2018-12. The effective date of ASU 2018-12 was deferred for all insurance entities by ASU 2019-09, Financial Services—Insurance: Effective Date (issued in October 2019) and by ASU 2020-11, Financial Services—Insurance: Effective Date and Early Application (issued in November 2020). Citi plans to adopt the targeted improvements in ASU 2018-12 on January 1, 2023 and is currently evaluating the impact of the standard on its insurance subsidiaries. Citi does not expect a material impact to its results of operations as a result of adopting the standard.

Discontinued Operations and Disposal Groups [Abstract]
DISCONTINUED OPERATIONS, SIGNIFICANT DISPOSALS AND OTHER BUSINESS EXITS	DISCONTINUED OPERATIONS, SIGNIFICANT DISPOSALS AND OTHER BUSINESS EXITS Discontinued Operations The Company’s results from Discontinued operations consisted of residual activities related to previously divested operations. All Discontinued operations results are recorded within Corporate/Other . The following table summarizes financial information for all Discontinued operations : Three Months Ended March 31, In millions of dollars 2022 2021 Total revenues, net of interest expense $ — $ — Income (loss) from discontinued operations (1) $ (2) $ (2) Benefit for income taxes — — Income (loss) from discontinued operations, net of taxes $ (2) $ (2) (1) Amounts in each period relate to the sale of the Egg Banking business in 2011. Cash flows from Discontinued operations were not material for the periods presented. Significant Disposals The following five consumer banking business sale agreements (of nine total) were identified as significant disposals that are recorded within the Legacy Franchises segment, including the assets and liabilities that were reclassified to HFS within Other assets and Other liabilities on the Consolidated Balance Sheet and the Income (loss) before taxes (benefits) related to each business. All sales agreements in the table below are subject to regulatory approvals and other closing conditions: Three Months Ended March 31, 2022 In millions of dollars Income (loss) before taxes (1) Assets Liabilities Consumer banking business in Sale agreement date Expected close 2022 2021 Cash and deposits with banks Loans (2) Goodwill (3) Other assets, advances to/from subsidiaries Other assets Total assets Deposits Long-term debt Other liabilities Total liabilities Australia (4) 8/9/21 first half 2022 $ 164 $ 73 $ 18 $ 9,370 $ 257 $ — $ 105 $ 9,750 $ 7,098 $ 451 $ 147 $ 7,696 Philippines (5) 12/23/21 second half 2022 40 36 30 1,161 244 570 35 2,040 1,386 — 82 1,468 Thailand (5) 1/14/22 second half 2022 $ (11) $ 48 $ 17 $ 2,545 $ 157 $ 223 $ 71 $ 3,013 $ 945 $ — $ 224 $ 1,169 Taiwan (5) 1/28/22 second half 2023 46 85 103 8,170 212 5,199 223 13,907 10,733 — 220 10,953 India (5) 3/30/22 first half 2023 72 69 33 3,669 346 2,984 129 7,161 6,579 — 185 6,764 (1) Income before taxes for the period in which the individually significant component was classified as HFS for all prior periods presented. For Australia, excludes the pretax loss on sale. (2) Loans, net of allowance as of March 31, 2022: Australia $145 million, Philippines $71 million, Thailand $71 million, Taiwan $66 million and India $69 million. (3) For Australia, includes intangible assets. (4) Beginning in the third quarter of 2021, Citi reported the business as HFS. In the third and fourth quarters of 2021, Citi recognized an aggregate pretax loss on sale of approximately $700 million ($600 million after-tax), subject to closing adjustments. The loss on sale primarily reflects the impact of a pretax $625 million currency translation adjustment (CTA) loss (net of hedges) ($475 million after-tax) already reflected in the Accumulated other comprehensive income (AOCI) component of equity. Upon closing, the CTA-related balance will be removed from the AOCI component of equity, resulting in a neutral CTA impact to Citi’s Common Equity Tier 1 Capital. In the first quarter of 2022, Citi recorded an additional pretax loss on sale of approximately $118 million recorded in Other revenue ($81 million after-tax), primarily reflecting the impact of a pretax ACL release of $104 million and contractual adjustments of $14 million. (5) These sales are expected to result in an after-tax gain upon closing. Citi did not have any other significant disposals to report as of March 31, 2022. As of May 9, 2022, Citi had not entered into any other definitive sales agreements related to its recently announced intention to pursue exits of its consumer franchises in 13 markets across Asia and EMEA. For a description of the Company’s significant disposal transactions in prior periods and financial impact, see Note 2 to the Consolidated Financial Statements in Citi’s 2021 Form 10-K. Other Business Exits Wind-Down of Korea Consumer Banking Business On October 25, 2021, Citi announced its decision to wind down and close its Korea consumer banking business, which is reported in the Legacy Franchises operating segment. In connection with the announcement, Citibank Korea Inc. (CKI) commenced a voluntary early termination program (Korea VERP). Due to the voluntary nature of this termination program, no liabilities for termination benefits are recorded until CKI makes formal offers to employees that are then irrevocably accepted by those employees. Related charges are recorded as Compensation and benefits . For the quarter ended March 31, 2022, Citigroup recorded an additional pretax charge of $31 million, composed of gross charges connected to the Korea VERP. The following table summarizes the reserve charges related to the Korea VERP and other initiatives reported in the Legacy Franchises operating segment and Corporate/Other : In millions of dollars Employee termination costs Total Citigroup (pretax) Original charges $ 1,052 Utilization (1) Foreign exchange 3 Balance at December 31, 2021 $ 1,054 Additional charges $ 31 Utilization (347) Foreign exchange (24) Balance at March 31, 2022 $ 714 The total estimated cash charges for the wind-down are $1.1 billion, most of which were recognized in 2021. Citi will recognize the remaining charges through 2022, as voluntary retirements are phased in and irrevocably accepted in order to minimize business and operational impacts.

OPERATING SEGMENTS

Segment Reporting [Abstract]
OPERATING SEGMENTS	OPERATING SEGMENTS Effective January 1, 2022, Citi changed its management structure resulting in changes in its operating segments and reporting units to reflect how the CEO, who is the chief operating decision maker, intends to manage the Company, allocate resources and measure performance. Citi reorganized its management reporting into three operating segments: Institutional Clients Group (ICG) , Personal Banking and Wealth Management (PBWM) and Legacy Franchises , with Corporate/Other including activities not assigned to a specific operating segment, as well as discontinued operations. The prior-period balances reflect reclassifications to conform the presentation in those periods to the current operating segment structure. Citi’s consolidated results were not impacted by the changes discussed above and remain unchanged for all periods presented. The operating segments are determined based on how management allocates resources and measures financial performance to make business decisions, and are reflective of the types of customers served and the products and services provided. ICG consists of Services, Markets and Banking, providing corporate, institutional and public sector clients around the world with a full range of wholesale banking products and services. PBWM consists of U.S. Personal Banking and Global Wealth Management , providing traditional banking services and credit cards to retail and small business customers in the U.S., and financial services to the entire continuum of wealth clients—from affluent to ultra-high-net-worth—through banking, lending, mortgages, investment, custody and trust product offerings in approximately 20 countries, including the U.S., Mexico and the four wealth management centers: Singapore, Hong Kong, the UAE and London. Legacy Franchises consists of Asia Consumer and Mexico Consumer/SBMM businesses that Citi intends to exit, and its remaining Legacy Holdings Assets . Corporate/Other includes activities not assigned to the operating segments, including certain unallocated costs of global functions, other corporate expenses and net treasury results, offsets to certain line-item reclassifications and eliminations, and unallocated taxes, as well as discontinued operations. The following tables present certain information regarding the Company’s continuing operations by operating segment and Corporate/Other : Three Months Ended March 31, In millions of dollars, except identifiable assets, average loans and average deposits in billions ICG PBWM Legacy Franchises Corporate/Other Total Citi 2022 2021 2022 2021 2022 2021 2022 2021 2022 2021 Net interest income $ 3,784 $ 3,733 $ 5,385 $ 5,165 $ 1,508 $ 1,563 $ 194 $ 45 $ 10,871 $ 10,506 Non-interest revenue 7,376 7,655 520 827 423 680 (4) (1) 8,315 9,161 Total revenues, net of interest expense $ 11,160 $ 11,388 $ 5,905 $ 5,992 $ 1,931 $ 2,243 $ 190 $ 44 $ 19,186 $ 19,667 Operating expense 6,723 5,932 3,889 3,422 2,293 1,752 260 307 13,165 11,413 Provision for credit losses 971 (1,539) (376) (557) 160 44 — (3) 755 (2,055) Income (loss) from continuing operations before taxes $ 3,466 $ 6,995 $ 2,392 $ 3,127 $ (522) $ 447 $ (70) $ (260) $ 5,266 $ 10,309 Provision (benefits) for income taxes 808 1,565 532 707 (137) 127 (262) (67) 941 2,332 Income (loss) from continuing operations $ 2,658 $ 5,430 $ 1,860 $ 2,420 $ (385) $ 320 $ 192 $ (193) $ 4,325 $ 7,977 Identifiable assets (March 31, 2022 and December 31, 2021) $ 1,704 $ 1,613 $ 476 $ 464 $ 122 $ 125 $ 92 $ 89 $ 2,394 $ 2,291 Average loans 289 281 312 303 48 82 — — 649 666 Average deposits 826 809 447 397 55 87 6 11 1,334 1,304

These agreements are subject to contractually based performance thresholds that, if met, would require Citi to make ongoing payments to the partner. The threshold is based on the profitability of a program and is generally calculated based on predefined program revenues less predefined program expenses. In most of Citi’s partner-sharing agreements, program expenses include net credit losses and, to the extent that the increase in net credit losses reduces Citi’s liability for the partners’ share for a given program year, would generally result in lower payments to partners in total for that year and vice versa. Further, in some instances, other partner payments are based on program sales and new account acquisitions. (2) Includes overdraft fees of $32 million and $24 million for the three months ended March 31, 2022 and 2021, respectively. Overdraft fees are accounted for under ASC 310.

(2) Gains due to settlement and curtailment relate to divestiture activities. (3) The U.S. qualified pension plan is fully funded under specified Employee Retirement Income Security Act of 1974, as amended (ERISA), funding rules as of January 1, 2022 and no minimum required funding is expected for 2022. (4) The nonqualified plans of the Company are unfunded. (5) The framework for the Company’s pension oversight process includes monitoring of potential settlement charges for all plans. Settlement accounting is triggered when either the sum of all settlements (including lump sum payments) for the year is greater than service plus interest costs or if more than 10% of the plan’s projected benefit obligation will be settled. Because some of Citi’s significant plans are frozen and have no material service cost, settlement accounting may apply in the future. The following table shows the change in AOCI related to the Company’s pension, postretirement and post employment plans: In millions of dollars Three Months Ended March 31, 2022 Twelve Months Ended December 31, 2021 Three Months Ended March 31, 2021 Beginning of period balance, net of tax (1)(2) $ (5,852) $ (6,864) $ (6,864) Actuarial assumptions changes and plan experience 1,525 963 1,430 Net asset loss due to difference between actual and expected returns (1,462) (148) (718) Net amortization 64 280 81 Prior service cost — (7) — Curtailment/settlement gain (3) — 11 — Foreign exchange impact and other 50 153 114 Change in deferred taxes, net (6) (240) (193) Change, net of tax $ 171 $ 1,012 $ 714 End of period balance, net of tax (1)(2) $ (5,681) $ (5,852) $ (6,150) (1) See Note 17 for further discussion of net AOCI balance. (2) Includes net-of-tax amounts for certain profit-sharing plans outside the U.S. (3) Curtailment and settlement relate to divestiture activities.

(2) Company contributions are composed of cash contributions made to the plans and benefits paid directly by the Company. (3) Estimated 2022 benefit payments have increased due to the wind-down of Citi’s consumer banking business in Korea, as it is expected that employees who elected the VERP will be withdrawing their pension plan assets. See Note 2 for additional information.

In these transactions, the Company recognizes the securities received at fair value within Other assets and the obligation to return those securities as a liability within Brokerage payables . (2) See Note 14 for further information. It is the Company’s policy to take possession of the underlying collateral, monitor its market value relative to the amounts due under the agreements and, when necessary, require prompt transfer of additional collateral in order to maintain contractual margin protection. For resale and repurchase agreements, when necessary, the Company posts additional collateral in order to maintain contractual margin protection. A substantial portion of the resale and repurchase agreements is recorded at fair value, as described in Notes 20 and 21. The remaining portion is carried at the amount of cash initially advanced or received, plus accrued interest, as specified in the respective agreements. A substantial portion of securities borrowing and lending agreements is recorded at the amount of cash advanced or received. The remaining portion is recorded at fair value as the Company elected the fair value option for certain securities borrowed and loaned portfolios, as described in Note 21. With respect to securities loaned, the Company receives cash collateral in an amount generally in excess of the market value of the securities loaned. The Company monitors the market value of securities borrowed and securities loaned on a daily basis and posts or obtains additional collateral in order to maintain contractual margin protection. The following tables present the gross and net resale and repurchase agreements and securities borrowing and lending agreements and the related offsetting amounts permitted under ASC 210-20-45. The tables also include amounts related to financial instruments that are not permitted to be offset under ASC 210-20-45, but would be eligible for offsetting to the extent that an event of default has occurred and a legal opinion supporting enforceability of the offsetting rights has been obtained. Remaining exposures continue to be secured by financial collateral, but the Company may not have sought or been able to obtain a legal opinion evidencing enforceability of the offsetting right.

HTM Debt Securities Delinquency and Non-Accrual Details Citi did not have any HTM securities that were delinquent or on non-accrual status at March 31, 2022 or December 31, 2021. There were no purchased credit-deteriorated HTM debt securities held by the Company as of March 31, 2022 or December 31, 2021. Evaluating Investments for Impairment AFS Debt Securities Overview—AFS Debt Securities The Company conducts periodic reviews of all AFS debt securities with unrealized losses to evaluate whether the impairment resulted from expected credit losses or from other factors and to evaluate the Company’s intent to sell such securities. An AFS debt security is impaired when the current fair value of an individual AFS debt security is less than its amortized cost basis. The Company recognizes the entire difference between amortized cost basis and fair value in earnings for impaired AFS debt securities that Citi has an intent to sell or for which Citi believes it will more-likely-than-not be required to sell prior to recovery of the amortized cost basis. However, for those AFS debt securities that the Company does not intend to sell and is not likely to be required to sell, only the credit-related impairment is recognized in earnings by recording an allowance for credit losses. Any remaining fair value decline for such securities is recorded in AOCI . The Company does not consider the length of time that the fair value of a security is below its amortized cost when determining if a credit loss exists. For AFS debt securities, credit losses exist where Citi does not expect to receive contractual principal and interest cash flows sufficient to recover the entire amortized cost basis of a security. The allowance for credit losses is limited to the amount by which the AFS debt security’s amortized cost basis exceeds its fair value. The allowance is increased or decreased if credit conditions subsequently worsen or improve. Reversals of credit losses are recognized in earnings. The sections below describe the Company’s process for identifying expected credit impairments for debt security types that have the most significant unrealized losses as of March 31, 2022. Mortgage-Backed Securities Citi records no allowances for credit losses on U.S. government-agency-guaranteed mortgage-backed securities, because the Company expects to incur no credit losses in the event of default due to a history of incurring no credit losses and due to the nature of the counterparties. State and Municipal Securities For AFS state and municipal bonds with unrealized losses that Citi plans to sell or would more-likely-than-not be required to sell, the full impairment is recognized in earnings. For AFS state and municipal bonds where Citi has no intent to sell and it is more-likely-than-not that the Company will not be required to sell, Citi records an allowance for expected credit losses for the amount it expects not to collect, capped at the difference between the bond’s amortized cost basis and fair value. Equity Method Investments For impaired equity method investments that Citi plans to sell prior to recovery of value or would more-likely-than-not be required to sell, with no expectation that the fair value will recover prior to the expected sale date, the full impairment is recognized as OTTI in Other revenue regardless of severity and duration. The measurement of the OTTI does not include partial projected recoveries subsequent to the balance sheet date. For impaired equity method investments that management does not plan to sell and is not more-likely-than-not to be required to sell prior to recovery of value, the evaluation of whether an impairment is other-than-temporary is based on (i) whether and when an equity method investment will recover in value and (ii) whether the investor has the intent and ability to hold that investment for a period of time sufficient to recover the value. For more information on evaluating investments for impairment, see Note 13 to the Consolidated Financial Statements in Citi’s 2021 Form 10-K.

The election to measure a non-marketable equity security using the measurement alternative is made on an instrument-by-instrument basis. Under the measurement alternative, an equity security is carried at cost plus or minus changes resulting from observable prices in orderly transactions for the identical or a similar investment of the same issuer. The carrying value of the equity security is adjusted to fair value on the date of an observed transaction. Fair value may differ from the observed transaction price due to a number of factors, including marketability adjustments and differences in rights and obligations when the observed transaction is not for the identical investment held by Citi. Equity securities under the measurement alternative are also assessed for impairment. On a quarterly basis, management qualitatively assesses whether each equity security under the measurement alternative is impaired. For details on impairment indicators that are considered, see Note 13 to the Consolidated Financial Statements in Citi’s 2021 Form 10-K. When the qualitative assessment indicates that impairment exists, the investment is written down to fair value, with the full difference between the fair value of the investment and its carrying amount recognized in earnings. Below is the carrying value of non-marketable equity securities measured using the measurement alternative at March 31, 2022 and December 31, 2021: In millions of dollars March 31, 2022 December 31, 2021 Measurement alternative: Carrying value $ 1,622 $ 1,413 Below are amounts recognized in earnings and life-to-date amounts for non-marketable equity securities measured using the measurement alternative: Three Months Ended March 31, In millions of dollars 2022 2021 Measurement alternative: (1) Impairment losses $ — $ — Downward changes for observable prices — — Upward changes for observable prices 85 81 (1) See Note 20 for additional information on these nonrecurring fair value measurements.

For the three months ended March 31, 2022 and 2021, there was no impairment loss recognized in earnings for non-marketable equity securities carried at cost. Investments in Alternative Investment Funds That Calculate Net Asset Value The Company holds investments in certain alternative investment funds that calculate net asset value (NAV), or its equivalent, including private equity funds, funds of funds and real estate funds, as provided by third-party asset managers. Investments in such funds are generally classified as non-marketable equity securities carried at fair value. The fair values of these investments are estimated using the NAV of the Company’s ownership interest in the funds. Some of these investments are in “covered funds” for purposes of the Volcker Rule, which prohibits certain proprietary investment activities and limits the ownership of, and relationships with, covered funds. On April 21, 2017, Citi’s request for extension of the permitted holding period under the Volcker Rule for certain of its investments in illiquid funds was approved, allowing the Company to hold such investments until the earlier of five years from the July 21, 2017 expiration date of the general conformance period or the date such investments mature or are otherwise conformed with the Volcker Rule.

(2) With respect to the Company’s investments in private equity funds and real estate funds, distributions from each fund will be received as the underlying assets held by these funds are liquidated. It is estimated that the underlying assets of these funds will be liquidated over a period of several years as market conditions allow. Private equity and real estate funds do not allow redemption of investments by their investors. Investors are permitted to sell or transfer their investments, subject to the approval of the general partner or investment manager of these funds, which generally may not be unreasonably withheld. (3) Includes several real estate funds that invest primarily in commercial real estate in the U.S., Europe and Asia. N/A Not applicable

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND INTANGIBLE ASSETS	GOODWILL AND INTANGIBLE ASSETS Goodwill The changes in Goodwill were as follows: In millions of dollars Institutional Clients Group Personal Banking and Wealth Management Legacy Franchises Total Balance at December 31, 2021 $ 9,215 $ 9,717 $ 2,367 $ 21,299 Impairment (1) — — (535) (535) Divestitures (2) — — (873) (873) Foreign currency translation (44) 18 — (26) Balance at March 31, 2022 $ 9,171 $ 9,735 $ 959 $ 19,865 (1) Goodwill impairment of $535 million (approximately $489 million after-tax) was incurred in the Asia Consumer reporting unit of Legacy Franchises due to the re-segmentation and timing of divestitures recorded in the first quarter. (2) Primarily relates to Citi’s agreement to sell its consumer banking businesses in Malaysia, Thailand, Indonesia, Vietnam, Taiwan, India and Bahrain within Asia Consumer, during the first quarter of 2022 and reclassified as HFS as of March 31, 2022. See Note 2. Citi tests goodwill for impairment annually as of July 1 (the annual test) and through interim assessments between annual tests if an event occurs or circumstances change that could more-likely-than-not reduce the fair value of a reporting unit below its carrying amount. The results of the 2021 annual impairment test resulted in no impairment. As discussed in Note 3, effective January 1, 2022, as part of its strategic refresh, Citi made changes to its management structure, which resulted in changes in its operating segments and reporting units to reflect how the CEO, who is the chief operating decision maker, intends to manage the Company, allocate resources and measure performance. Goodwill balances were reallocated across the new reporting units based on their relative fair values using the valuation performed as of the effective date of the reorganization. Further, the Goodwill balances associated with certain Asia Consumer businesses within the Legacy Franchises operating segment were reclassified to HFS as of March 31, 2022. See Note 2 for a discussion of Citi’s divestiture activities. The reorganization of Citi’s reporting structure and the announced sales of businesses within a reporting unit were identified as triggering events for purposes of goodwill impairment testing. Consistent with the requirements of ASC 350, interim goodwill impairment tests were performed that resulted in an impairment of $535 million to the Asia Consumer reporting unit within the Legacy Franchises operating segment, due to the implementation of Citi’s revised operating segments and reporting units, as well as the timing of the announced sales of its Asia consumer banking businesses. This impairment was recorded in the first quarter of 2022 as an operating expense. To determine the goodwill impairment, Citi used a combination of the income approach, market approach and bids from buyers, where available, to determine the fair value of the Asia Consumer reporting unit. Under the market approach, Citi estimated fair value by comparing the business to similar businesses or guideline companies whose securities are actively traded in public markets. Under the income approach, Citi used a discounted cash flow (DCF) model in which cash flows anticipated over several periods, plus a terminal value at the end of that time horizon, are discounted to their present value using an appropriate rate that is commensurate with the risk inherent within the reporting unit. The key assumptions used to determine the fair value of the Asia Consumer reporting unit consisted primarily of significant unobservable inputs (Level 3 fair value inputs), including discount rates, estimated cash flows, growth rates, earnings multiples and/or transaction multiples of similar businesses or guideline public companies, and bids from buyers. The DCF method employs a capital asset pricing model in estimating the discount rate based on several factors including market interest rates, and includes adjustments for market risk and company-specific risk. Estimated cash flows are based on internally developed estimates and the growth rates are based on industry knowledge and historical performance. Based on the interim impairment tests, the fair values of all of Citi’s other reporting units as a percentage of their allocated carrying values ranged from approximately 114% to 267%, resulting in no further impairment recognized as of March 31, 2022. While the inherent risk of uncertainty is embedded in the key assumptions used in the valuations, the economic and business environments continue to evolve as management implements its strategic refresh. If management’s future estimate of key economic and market assumptions were to differ from its current assumptions, Citi could potentially experience material goodwill impairment charges in the future. See Note 3 for a description of Citi’s operating segments.

CHANGES IN ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS) (AOCI)	CHANGES IN ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS) (AOCI) Changes in each component of Citigroup’s Accumulated other comprehensive income (loss) were as follows: Three Months Ended March 31, 2022 In millions of dollars Net Debt valuation adjustment (DVA) (1) Cash flow hedges (2) Benefit plans (3) Foreign (4)(5) Excluded component of fair value hedges Accumulated Balance, December 31, 2021 $ (614) $ (1,187) $ 101 $ (5,852) $ (31,166) $ (47) $ (38,765) Other comprehensive income before (4,283) 793 (1,324) 292 (14) 46 (4,490) Increase (decrease) due to amounts reclassified from AOCI 6 — (217) (121) — 2 (330) Change, net of taxes $ (4,277) $ 793 $ (1,541) $ 171 $ (14) $ 48 $ (4,820) Balance at March 31, 2022 $ (4,891) $ (394) $ (1,440) $ (5,681) $ (31,180) $ 1 $ (43,585) Three Months Ended March 31, 2021 In millions of dollars Net Debt valuation adjustment (DVA) (1) Cash flow hedges (2) Benefit plans (3) Foreign of hedges (4) Excluded component of fair value hedges Accumulated Balance, December 31, 2020 $ 3,320 $ (1,419) $ 1,593 $ (6,864) $ (28,641) $ (47) $ (32,058) Other comprehensive income before (1,519) (84) (344) 653 (1,274) (10) (2,578) Increase (decrease) due to amounts reclassified from AOCI (266) 42 (212) 61 — — (375) Change, net of taxes $ (1,785) $ (42) $ (556) $ 714 $ (1,274) $ (10) $ (2,953) Balance at March 31, 2021 $ 1,535 $ (1,461) $ 1,037 $ (6,150) $ (29,915) $ (57) $ (35,011) (1) Reflects the after-tax valuation of Citi’s fair value option liabilities. See “Market Valuation Adjustments” in Note 20. (2) Primarily driven by Citi’s pay floating/receive fixed interest rate swap programs that hedge certain floating rates on assets. (3) Primarily reflects adjustments based on the quarterly actuarial valuations of the Company’s significant pension and postretirement plans, annual actuarial valuations of all other plans and amortization of amounts previously recognized in other comprehensive income. (4) Primarily reflects the movements in (by order of impact) the Brazilian real, Japanese yen, Mexican peso, South Korean won, Euro, Chilean peso and Indian rupee against the U.S. dollar and changes in related tax effects and hedges for the three months ended March 31, 2022. Primarily reflects the movements in (by order of impact) the Mexican peso, Euro, South Korean won, Japanese yen, Polish zloty and Brazilian real against the U.S. dollar and changes in related tax effects and hedges for the three months ended March 31, 2021. Amounts recorded in the CTA component of AOCI remain in AOCI until the sale or substantial liquidation of the foreign entity, at which point such amounts related to the foreign entity are reclassified into earnings. (5) March 31, 2022 includes an approximate $475 million (after-tax) ($625 million pretax) currency translation adjustment (CTA) loss (net of hedges) associated with Citi’s agreement to sell its consumer banking business in Australia (see Note 2). The loss on sale primarily reflects the impact of the CTA loss (net of hedges) already reflected in AOCI. Upon closing, the CTA-related balance will be removed from AOCI , resulting in a neutral impact from CTA to Citi’s Common Equity Tier 1 Capital. The pretax and after-tax changes in each component of Accumulated other comprehensive income (loss) were as follows: Three Months Ended March 31, 2022 In millions of dollars Pretax Tax effect After-tax Balance, December 31, 2021 $ (45,383) $ 6,618 $ (38,765) Change in net unrealized gains (losses) on debt securities (5,624) 1,347 (4,277) Debt valuation adjustment (DVA) 1,050 (257) 793 Cash flow hedges (2,022) 481 (1,541) Benefit plans 177 (6) 171 Foreign currency translation adjustment (69) 55 (14) Excluded component of fair value hedges 64 (16) 48 Change $ (6,424) $ 1,604 $ (4,820) Balance at March 31, 2022 $ (51,807) $ 8,222 $ (43,585) Three Months Ended March 31, 2021 In millions of dollars Pretax Tax effect After-tax Balance, December 31, 2020 $ (36,992) $ 4,934 $ (32,058) Change in net unrealized gains (losses) on debt securities (2,427) 642 (1,785) Debt valuation adjustment (DVA) (38) (4) (42) Cash flow hedges (729) 173 (556) Benefit plans 907 (193) 714 Foreign currency translation adjustment (1,339) 65 (1,274) Excluded component of fair value hedges (13) 3 (10) Change $ (3,639) $ 686 $ (2,953) Balance, March 31, 2021 $ (40,631) $ 5,620 $ (35,011) The Company recognized pretax (gains) losses related to amounts in AOCI reclassified to the Consolidated Statement of Income as follows: Increase (decrease) in AOCI due to Three Months Ended March 31, In millions of dollars 2022 2021 Realized (gains) losses on sales of investments $ (80) $ (401) Gross impairment losses 90 69 Subtotal, pretax $ 10 $ (332) Tax effect (4) 66 Net realized (gains) losses on investments after-tax (1) $ 6 $ (266) Realized DVA (gains) losses on fair value option liabilities, pretax $ — $ 56 Tax effect — (14) Net realized DVA, after-tax $ — $ 42 Interest rate contracts $ (286) $ (278) Foreign exchange contracts 1 1 Subtotal, pretax $ (285) $ (277) Tax effect 68 65 Amortization of cash flow hedges, after-tax (2) $ (217) $ (212) Amortization of unrecognized: Prior service cost (benefit) $ (6) $ (6) Net actuarial loss 70 87 Curtailment/settlement impact (3) (216) — Subtotal, pretax $ (152) $ 81 Tax effect 31 (20) Amortization of benefit plans, after-tax (3) $ (121) $ 61 Excluded component of fair value hedges, pretax $ 3 $ — Tax effect (1) — Excluded component of fair value hedges, after-tax $ 2 $ — Foreign currency translation adjustment, pretax $ — $ — Tax effect — — Foreign currency translation adjustment, after-tax $ — $ — Total amounts reclassified out of AOCI , pretax $ (424) $ (472) Total tax effect 94 97 Total amounts reclassified out of AOCI , after-tax $ (330) $ (375) (1) The pretax amount is reclassified to Realized gains (losses) on sales of investments, net and Gross impairment losses in the Consolidated Statement of Income.

Securitizations and Variable Interest Entities [Abstract]
SECURITIZATIONS AND VARIABLE INTEREST ENTITIES	SECURITIZATIONS AND VARIABLE INTEREST ENTITIES For additional information regarding Citi’s use of special purpose entities (SPEs) and variable interest entities (VIEs), see Note 21 to the Consolidated Financial Statements in Citi’s 2021 Form 10-K. Citigroup’s involvement with consolidated and unconsolidated VIEs with which the Company holds significant variable interests or has continuing involvement through servicing a majority of the assets in a VIE is presented below: As of March 31, 2022 Maximum exposure to loss in significant unconsolidated VIEs (1) Funded exposures (2) Unfunded exposures In millions of dollars Total Consolidated Significant unconsolidated VIE assets (3) Debt Equity Funding Guarantees Total Credit card securitizations $ 31,081 $ 31,081 $ — $ — $ — $ — $ — $ — Mortgage securitizations (4) U.S. agency-sponsored 116,330 — 116,330 1,653 — — 52 1,705 Non-agency-sponsored 58,449 605 57,844 2,426 — 11 — 2,437 Citi-administered asset-backed commercial paper conduits 13,588 13,588 — — — — — — Collateralized loan obligations (CLOs) 7,315 — 7,315 2,608 — — — 2,608 Asset-based financing (5) 260,573 10,614 249,959 34,590 1,112 12,288 — 47,990 Municipal securities tender option bond trusts (TOBs) 3,410 886 2,524 21 — 1,736 — 1,757 Municipal investments 20,961 3 20,958 2,611 3,593 3,821 — 10,025 Client intermediation 832 392 440 66 — — 63 129 Investment funds 378 89 289 2 — 15 1 18 Other — — — — — — — — Total $ 512,917 $ 57,258 $ 455,659 $ 43,977 $ 4,705 $ 17,871 $ 116 $ 66,669 As of December 31, 2021 Maximum exposure to loss in significant unconsolidated VIEs (1) Funded exposures (2) Unfunded exposures In millions of dollars Total Consolidated Significant unconsolidated VIE assets (3) Debt Equity Funding Guarantees Total Credit card securitizations $ 31,518 $ 31,518 $ — $ — $ — $ — $ — $ — Mortgage securitizations (4) U.S. agency-sponsored 113,641 — 113,641 1,582 — — 43 1,625 Non-agency-sponsored 60,851 632 60,219 2,479 — 5 — 2,484 Citi-administered asset-backed commercial paper conduits 14,018 14,018 — — — — — — Collateralized loan obligations (CLOs) 8,302 — 8,302 2,636 — — — 2,636 Asset-based financing (5) 246,632 11,085 235,547 32,242 1,139 12,189 — 45,570 Municipal securities tender option bond trusts (TOBs) 3,251 905 2,346 2 — 1,498 — 1,500 Municipal investments 20,597 3 20,594 2,512 3,617 3,562 — 9,691 Client intermediation 904 297 607 75 — — 224 299 Investment funds 498 179 319 — — 12 1 13 Other — — — — — — — — Total $ 500,212 $ 58,637 $ 441,575 $ 41,528 $ 4,756 $ 17,266 $ 268 $ 63,818 (1) The definition of maximum exposure to loss is included in the text that follows this table. (2) Included on Citigroup’s March 31, 2022 and December 31, 2021 Consolidated Balance Sheet. (3) A significant unconsolidated VIE is an entity in which the Company has any variable interest or continuing involvement considered to be significant, regardless of the likelihood of loss. (4) Citigroup mortgage securitizations also include agency and non-agency (private label) re-securitization activities. These SPEs are not consolidated. See “Re-securitizations” below for further discussion. (5) Included within this line are loans to third-party sponsored private equity funds, which represent $100 billion and $100 billion in unconsolidated VIE assets and $498 million and $497 million in maximum exposure to loss as of March 31, 2022 and December 31, 2021, respectively. The previous tables do not include: • certain venture capital investments made by some of the Company’s private equity subsidiaries, as the Company accounts for these investments in accordance with the Investment Company Audit Guide (codified in ASC 946); • certain investment funds for which the Company provides investment management services and personal estate trusts for which the Company provides administrative, trustee and/or investment management services; • certain third-party sponsored private equity funds to which the Company provides secured credit facilities. The Company has no decision-making power and does not consolidate these funds, some of which may meet the definition of a VIE. The Company’s maximum exposure to loss is generally limited to a loan or lending-related commitment. As of March 31, 2022 and December 31, 2021, the Company’s maximum exposure to loss related to these deals was $54.8 billion and $55.6 billion, respectively (for more information on these positions, see Note 13 and Note 26 to the Consolidated Financial Statements in Citigroup’s 2021 Form 10-K); • certain VIEs structured by third parties in which the Company holds securities in inventory, as these investments are made on arm’s-length terms; • certain positions in mortgage- and asset-backed securities held by the Company, which are classified as Trading account assets or Investments , in which the Company has no other involvement with the related securitization entity deemed to be significant (see Notes 12 and 20 for more information on these positions); • certain representations and warranties exposures in Citigroup residential mortgage securitizations, in which the original mortgage loan balances are no longer outstanding; and • VIEs such as trust preferred securities trusts used in connection with the Company’s funding activities. The Company does not have a variable interest in these trusts. The asset balances for consolidated VIEs represent the carrying amounts of the assets consolidated by the Company. The carrying amount may represent the amortized cost or the current fair value of the assets depending on the classification of the asset (e.g., loan or security) and the associated accounting model ascribed to that classification. The asset balances for unconsolidated VIEs in which the Company has significant involvement represent the most current information available to the Company. In most cases, the asset balances represent an amortized cost basis without regard to impairments, unless fair value information is readily available to the Company. The maximum funded exposure represents the balance sheet carrying amount of the Company’s investment in the VIE. It reflects the initial amount of cash invested in the VIE, adjusted for any accrued interest and cash principal payments received. The carrying amount may also be adjusted for increases or declines in fair value or any impairment in value recognized in earnings. The maximum exposure of unfunded positions represents the remaining undrawn committed amount, including liquidity and credit facilities provided by the Company or the notional amount of a derivative instrument considered to be a variable interest. In certain transactions, the Company has entered into derivative instruments or other arrangements that are not considered variable interests in the VIE (e.g., interest rate swaps, cross-currency swaps or where the Company is the purchaser of credit protection under a credit default swap or total return swap where the Company pays the total return on certain assets to the SPE). Receivables under such arrangements are not included in the maximum exposure amounts. Funding Commitments for Significant Unconsolidated VIEs—Liquidity Facilities and Loan Commitments The following table presents the notional amount of liquidity facilities and loan commitments that are classified as funding commitments in the VIE tables above: March 31, 2022 December 31, 2021 In millions of dollars Liquidity Loan/equity Liquidity Loan/equity Non-agency-sponsored mortgage securitizations $ — $ 11 $ — $ 5 Asset-based financing — 12,288 — 12,189 Municipal securities tender option bond trusts (TOBs) 1,736 — 1,498 — Municipal investments — 3,821 — 3,562 Investment funds — 15 — 12 Other — — — — Total funding commitments $ 1,736 $ 16,135 $ 1,498 $ 15,768 Significant Interests in Unconsolidated VIEs—Balance Sheet Classification The following table presents the carrying amounts and classification of significant variable interests in unconsolidated VIEs: In billions of dollars March 31, 2022 December 31, 2021 Cash $ — $ — Trading account assets 1.4 1.4 Investments 8.8 8.8 Total loans, net of allowance 37.6 35.4 Other 1.0 0.8 Total assets $ 48.8 $ 46.4 Credit Card Securitizations Substantially all of the Company’s credit card securitization activity is through two trusts—Citibank Credit Card Master Trust (Master Trust) and Citibank Omni Trust (Omni Trust), with the substantial majority through the Master Trust. These trusts are consolidated entities. The following table reflects amounts related to the Company’s securitized credit card receivables: In billions of dollars March 31, 2022 December 31, 2021 Ownership interests in principal amount of trust credit card receivables Sold to investors via trust-issued securities $ 9.7 $ 9.7 Retained by Citigroup as trust-issued securities 6.5 7.2 Retained by Citigroup via non-certificated interests 16.2 16.1 Total $ 32.4 $ 33.0 The following table summarizes selected cash flow information related to Citigroup’s credit card securitizations: Three Months Ended March 31, In billions of dollars 2022 2021 Proceeds from new securitizations $ — $ — Pay down of maturing notes — (3.6) Master Trust Liabilities (at Par Value) The weighted average maturity of the third-party term notes issued by the Master Trust was 3.3 years as of March 31, 2022 and 3.6 years as of December 31, 2021.

Gains recognized on the securitization of U.S. agency-sponsored mortgages were $0.3 million for the three months ended March 31, 2022. For the three months ended March 31, 2022, gains recognized on the securitization of non-agency-sponsored mortgages were $39 million. Gains recognized on the securitization of U.S. agency-sponsored mortgages were $1 million for the three months ended March 31, 2021. Gains recognized on the securitization of non-agency-sponsored mortgages were $166 million for the three months ended March 31, 2021. March 31, 2022 December 31, 2021 Non-agency-sponsored mortgages (1) Non-agency-sponsored mortgages (1) In millions of dollars U.S. agency- Senior (2) Subordinated U.S. agency- Senior Subordinated Carrying value of retained interests (3) $ 504 $ 1,234 $ 819 $ 374 $ 1,452 $ 955 (1) Disclosure of non-agency-sponsored mortgages as senior and subordinated interests is indicative of the interests’ position in the capital structure of the securitization. (2) Senior interests in non-agency-sponsored mortgages include $62 million related to personal loan securitizations at March 31, 2022. (3) Retained interests consist of Level 2 and Level 3 assets depending on the observability of significant inputs. See Note 20 for more information about fair value measurements. Key assumptions used in measuring the fair value of retained interests at the date of sale or securitization of mortgage receivables were as follows: Three Months Ended March 31, 2022 Non-agency-sponsored mortgages (1) U.S. agency- sponsored mortgages Senior interests Subordinated interests Weighted average discount rate 7.1 % 1.9 % 2.8 % Weighted average constant prepayment rate 3.3 % 6.2 % 11.9 % Weighted average anticipated net credit losses (2) NM 0.4 % 0.2 % Weighted average life 8.3 years 3.7 years 4.6 years Three Months Ended March 31, 2021 Non-agency-sponsored mortgages (1) U.S. agency- Senior Subordinated Weighted average discount rate 8.8 % 0.2 % 3.2 % Weighted average constant prepayment rate 5.8 % — % 12.5 % Weighted average anticipated net credit losses (2) NM 0.4 % 1.7 % Weighted average life 7.7 years 0.8 years NM (1) Disclosure of non-agency-sponsored mortgages as senior and subordinated interests is indicative of the interests’ position in the capital structure of the securitization. (2) Anticipated net credit losses represent estimated loss severity associated with defaulted mortgage loans underlying the mortgage securitizations disclosed above. Anticipated net credit losses, in this instance, do not represent total credit losses incurred to date, nor do they represent credit losses expected on retained interests in mortgage securitizations. NM Anticipated net credit losses are not meaningful due to U.S. agency guarantees. The interests retained by the Company range from highly rated and/or senior in the capital structure to unrated and/or residual interests. Key assumptions used in measuring the fair value of retained interests in securitizations of mortgage receivables at period end were as follows: March 31, 2022 Non-agency-sponsored mortgages (1) U.S. agency- Senior Subordinated Weighted average discount rate 4.9 % 9.3 % 4.9 % Weighted average constant prepayment rate 8.5 % 9.6 % 10.0 % Weighted average anticipated net credit losses (2) NM 1.0 % 2.0 % Weighted average life 6.7 years 7.0 years 10.8 years December 31, 2021 Non-agency-sponsored mortgages (1) U.S. agency- Senior Subordinated Weighted average discount rate 3.7 % 16.2 % 4.0 % Weighted average constant prepayment rate 14.5 % 6.8 % 9.0 % Weighted average anticipated net credit losses (2) NM 1.0 % 2.0 % Weighted average life 5.1 years 8.8 years 18.0 years (1) Disclosure of non-agency-sponsored mortgages as senior and subordinated interests is indicative of the interests’ position in the capital structure of the securitization. (2) Anticipated net credit losses represent estimated loss severity associated with defaulted mortgage loans underlying the mortgage securitizations disclosed above. Anticipated net credit losses, in this instance, do not represent total credit losses incurred to date, nor do they represent credit losses expected on retained interests in mortgage securitizations. NM Anticipated net credit losses are not meaningful due to U.S. agency guarantees. The sensitivity of the fair value to adverse changes of 10% and 20% in each of the key assumptions is presented in the tables below. The negative effect of each change is calculated independently, holding all other assumptions constant. Because the key assumptions may not be independent, the net effect of simultaneous adverse changes in the key assumptions may be less than the sum of the individual effects shown below.

Mortgage Servicing Rights (MSRs) The fair value of Citi’s capitalized MSRs was $520 million and $433 million at March 31, 2022 and 2021, respectively. The MSRs correspond to principal loan balances of $58 billion and $52 billion as of March 31, 2022 and 2021, respectively. The following table summarizes the changes in capitalized MSRs: Three Months Ended March 31, In millions of dollars 2022 2021 Balance, beginning of period $ 404 $ 336 Originations 34 43 Changes in fair value of MSRs due to changes in inputs and assumptions 98 73 Other changes (1) (17) (19) Sales of MSRs — — Balance, as of March 31 $ 520 $ 433 (1) Represents changes due to customer payments and passage of time. The fair value of the MSRs is primarily affected by changes in prepayments of mortgages that result from shifts in mortgage interest rates. Specifically, higher interest rates tend to lead to declining prepayments, which causes the fair value of the MSRs to increase. In managing this risk, Citigroup economically hedges a significant portion of the value of its MSRs through the use of interest rate derivative contracts, forward purchase and sale commitments of mortgage-backed securities and purchased securities, all classified as Trading account assets . The Company receives fees during the course of servicing previously securitized mortgages. The amounts of these fees were as follows: Three Months Ended March 31, In millions of dollars 2022 2021 Servicing fees $ 29 $ 31 Late fees 1 1 Ancillary fees — — Total MSR fees $ 30 $ 32 In the Consolidated Statement of Income these fees are primarily classified as Commissions and fees , and changes in MSR fair values are classified as Other revenue . Re-securitizations The Company engages in re-securitization transactions in which debt securities are transferred to a VIE in exchange for new beneficial interests. Citi did not transfer non-agency (private label) securities to re-securitization entities during the three months ended March 31, 2022 and 2021. These securities are backed by either residential or commercial mortgages and are often structured on behalf of clients. As of March 31, 2022 and December 31, 2021, Citi held no retained interests in private label re-securitization transactions structured by Citi. The Company also re-securitizes U.S. government-agency-guaranteed mortgage-backed (agency) securities. During the three months ended March 31, 2022, Citi transferred agency securities with a fair value of approximately $9.3 billion to re-securitization entities, compared to approximately $13.1 billion for the three months ended March 31, 2021. As of March 31, 2022, the fair value of Citi-retained interests in agency re-securitization transactions structured by Citi totaled approximately $1.2 billion (including $300 million related to re-securitization transactions executed in 2022) unchanged from to $1.2 billion as of December 31, 2021 (including $641 million related to re-securitization transactions executed in 2021), which is recorded in Trading account assets . The original fair values of agency re-securitization transactions in which Citi holds a retained interest as of March 31, 2022 and December 31, 2021 were approximately $80.3 billion and $78.4 billion, respectively. As of March 31, 2022 and December 31, 2021, the Company did not consolidate any private label or agency re-securitization entities. Citi-Administered Asset-Backed Commercial Paper Conduits At March 31, 2022 and December 31, 2021, the commercial paper conduits administered by Citi had approximately $13.6 billion and $14 billion of purchased assets outstanding, respectively, and had incremental funding commitments with clients of approximately $16.7 billion and $18.3 billion, respectively. Substantially all of the funding of the conduits is in the form of short-term commercial paper. At March 31, 2022 and December 31, 2021, the weighted average remaining lives of the commercial paper issued by the conduits were approximately 63 and 70 days, respectively. The primary credit enhancement provided to the conduit investors is in the form of transaction-specific credit enhancements described above. Each asset purchased by the conduit is structured with transaction-specific credit enhancement features provided by the third-party client seller, including over-collateralization, cash and excess spread collateral accounts, direct recourse or third-party guarantees. These credit enhancements are sized with the objective of approximating a credit rating of A or above, based on Citi’s internal risk ratings. In addition to the transaction-specific credit enhancements, the conduits, other than the government-guaranteed loan conduit, have obtained letters of credit from the Company, which equal at least 8% to 10% of the conduit’s assets with a minimum of $200 million. The letters of credit provided by the Company to the conduits total approximately $1.2 billion and $1.3 billion as of March 31, 2022 and December 31, 2021, respectively. The net result across multi-seller conduits administered by the Company is that, in the event that defaulted assets exceed the transaction-specific credit enhancements described above, any losses in each conduit are allocated first to the Company and then to the commercial paper investors. At March 31, 2022 and December 31, 2021, the Company owned $4.5 billion and $4.9 billion, respectively, of the commercial paper issued by its administered conduits. The Company’s investments were not driven by market illiquidity and the Company is not obligated under any agreement to purchase the commercial paper issued by the conduits. Collateralized Loan Obligations (CLOs) There were no new securitizations during the three months ended March 31, 2022 and 2021. The following table summarizes selected retained interests related to Citigroup CLOs: In millions of dollars Mar. 31, 2022 Dec. 31, 2021 Carrying value of retained interests $ 921 $ 921 All of Citi’s retained interests were held-to-maturity securities as of March 31, 2022 and December 31, 2021. Municipal Securities Tender Option Bond (TOB) Trusts At March 31, 2022 and December 31, 2021, none of the municipal bonds owned by non-customer TOB trusts were subject to a credit guarantee provided by the Company. At March 31, 2022 and December 31, 2021, liquidity agreements provided with respect to customer TOB trusts totaled $1.8 billion and $1.5 billion, respectively, of which $0.8 billion and $0.6 billion, respectively, were offset by reimbursement agreements. For the remaining exposure related to TOB transactions, where the residual owned by the customer was at least 25% of the bond value at the inception of the transaction, no reimbursement agreement was executed. The Company also provides other liquidity agreements or letters of credit to customer-sponsored municipal investment funds, which are not variable interest entities, and municipality-related issuers that totaled $1.8 billion and $2 billion as of March 31, 2022 and December 31, 2021, respectively. These liquidity agreements and letters of credit are offset by reimbursement agreements with various term-out provisions. Asset-Based Financing The primary types of Citi’s asset-based financings, total assets of the unconsolidated VIEs with significant involvement and Citi’s maximum exposure to loss are shown below. For Citi to realize the maximum loss, the VIE (borrower) would have to default with no recovery from the assets held by the VIE.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	DERIVATIVES In the ordinary course of business, Citigroup enters into various types of derivative transactions. All derivatives are recorded in Trading account assets/Trading account liabilities on the Consolidated Balance Sheet. For additional information regarding Citi’s use of and accounting for derivatives, see Note 22 to the Consolidated Financial Statements in Citi’s 2021 Form 10-K. Information pertaining to Citigroup’s derivatives activities, based on notional amounts, is presented in the table below. Derivative notional amounts are reference amounts from which contractual payments are derived and do not represent a complete measure of Citi’s exposure to derivative transactions. Citi’s derivative exposure arises primarily from market fluctuations (i.e., market risk), counterparty failure (i.e., credit risk) and/or periods of high volatility or financial stress (i.e., liquidity risk), as well as any market valuation adjustments that may be required on the transactions. Moreover, notional amounts do not reflect the netting of offsetting trades. For example, if Citi enters into a receive-fixed interest rate swap with $100 million notional, and offsets this risk with an identical but opposite pay-fixed position with a different counterparty, $200 million in derivative notionals is reported, although these offsetting positions may result in de minimis overall market risk. In addition, aggregate derivative notional amounts can fluctuate from period to period in the normal course of business based on Citi’s market share, levels of client activity and other factors. Derivative Notionals Hedging instruments under ASC 815 Trading derivative instruments In millions of dollars March 31, December 31, March 31, December 31, Interest rate contracts Swaps $ 347,532 $ 267,035 $ 23,502,556 $ 21,873,538 Futures and forwards — — 2,506,531 2,383,702 Written options — — 1,755,712 1,584,451 Purchased options — — 1,674,204 1,428,376 Total interest rate contracts $ 347,532 $ 267,035 $ 29,439,003 $ 27,270,067 Foreign exchange contracts Swaps $ 51,450 $ 47,298 $ 6,661,315 $ 6,288,193 Futures, forwards and spot 52,058 50,926 4,030,636 4,316,242 Written options — — 835,410 664,942 Purchased options — — 813,452 651,958 Total foreign exchange contracts $ 103,508 $ 98,224 $ 12,340,813 $ 11,921,335 Equity contracts Swaps $ — $ — $ 254,925 $ 269,062 Futures and forwards — — 78,957 71,363 Written options — — 499,900 492,433 Purchased options — — 404,963 398,129 Total equity contracts $ — $ — $ 1,238,745 $ 1,230,987 Commodity and other contracts Swaps $ — $ — $ 108,594 $ 91,962 Futures and forwards 2,327 2,096 196,630 157,195 Written options — — 59,744 51,224 Purchased options — — 58,796 47,868 Total commodity and other contracts $ 2,327 $ 2,096 $ 423,764 $ 348,249 Credit derivatives (1) Protection sold $ — $ — $ 714,636 $ 572,486 Protection purchased — — 770,692 645,996 Total credit derivatives $ — $ — $ 1,485,328 $ 1,218,482 Total derivative notionals $ 453,367 $ 367,355 $ 44,927,653 $ 41,989,120 (1) Credit derivatives are arrangements designed to allow one party (protection purchaser) to transfer the credit risk of a “reference asset” to another party (protection seller). These arrangements allow a protection seller to assume the credit risk associated with the reference asset without directly purchasing that asset. The Company enters into credit derivative positions for purposes such as risk management, yield enhancement, reduction of credit concentrations and diversification of overall risk. The following tables present the gross and net fair values of the Company’s derivative transactions and the related offsetting amounts as of March 31, 2022 and December 31, 2021. Gross positive fair values are offset against gross negative fair values by counterparty, pursuant to enforceable master netting agreements. Under ASC 815-10-45, payables and receivables in respect of cash collateral received from or paid to a given counterparty pursuant to a credit support annex are included in the offsetting amount if a legal opinion supporting the enforceability of netting and collateral rights has been obtained. GAAP does not permit similar offsetting for security collateral. In addition, the following tables reflect rule changes adopted by clearing organizations that require or allow entities to treat certain derivative assets, liabilities and the related variation margin as settlement of the related derivative fair values for legal and accounting purposes, as opposed to presenting gross derivative assets and liabilities that are subject to collateral, whereby the counterparties would also record a related collateral payable or receivable. As a result, the tables reflect a reduction of approximately $430 billion and $340 billion as of March 31, 2022 and December 31, 2021, respectively, of derivative assets and derivative liabilities that previously would have been reported on a gross basis, but are now legally settled and not subject to collateral. The tables also present amounts that are not permitted to be offset, such as security collateral or cash collateral posted at third-party custodians, but which would be eligible for offsetting to the extent that an event of default has occurred and a legal opinion supporting enforceability of the netting and collateral rights has been obtained.

For the three months ended March 31, 2022 and 2021, amounts recognized in Principal transactions in the Consolidated Statement of Income include certain derivatives not designated in a qualifying hedging relationship. Citigroup presents this disclosure by business classification, showing derivative gains and losses related to its trading activities together with gains and losses related to non-derivative instruments within the same trading portfolios, as this represents how these portfolios are risk managed. See Note 6 for further information. The amounts recognized in Other revenue in the Consolidated Statement of Income related to derivatives not designated in a qualifying hedging relationship are shown below. The table below does not include any offsetting gains (losses) on the economically hedged items to the extent that such amounts are also recorded in Other revenue . Gains (losses) included in Three Months Ended March 31, In millions of dollars 2022 2021 Interest rate contracts $ 72 $ (60) Foreign exchange (77) (21) Total $ (5) $ (81) Fair Value Hedges Hedging of Benchmark Interest Rate Risk Citigroup’s fair value hedges are primarily hedges of fixed-rate long-term debt or assets, such as available-for-sale debt securities or loans. For qualifying fair value hedges of interest rate risk, the changes in the fair value of the derivative and the change in the fair value of the hedged item attributable to the hedged risk are presented within Interest revenue or Interest expense based on whether the hedged item is an asset or a liability. Citigroup has executed a last-of-layer hedge, which permits an entity to hedge the interest rate risk of a stated portion of a closed portfolio of prepayable financial assets that are expected to remain outstanding for the designated tenor of the hedge. In accordance with ASC 815, an entity may exclude prepayment risk when measuring the change in fair value of the hedged item attributable to interest rate risk under the last-of-layer approach. Similar to other fair value hedges, where the hedged item is an asset, the fair value of the hedged item attributable to interest rate risk will be presented in Interest revenue along with the change in the fair value of the hedging instrument. Hedging of Foreign Exchange Risk Citigroup hedges the change in fair value attributable to foreign exchange rate movements in available-for-sale debt securities and long-term debt that are denominated in currencies other than the functional currency of the entity holding the securities or issuing the debt. The hedging instrument is generally a forward foreign exchange contract or a cross-currency swap contract. Citigroup considers the premium associated with forward contracts (i.e., the differential between the spot and contractual forward rates) as the cost of hedging; this amount is excluded from the assessment of hedge effectiveness and is generally reflected directly in earnings over the life of the hedge. Citi also excludes changes in cross-currency basis associated with cross-currency swaps from the assessment of hedge effectiveness and records it in Other comprehensive income. Hedging of Commodity Price Risk Citigroup hedges the change in fair value attributable to spot price movements in physical commodities inventories. The hedging instrument is a futures contract to sell the underlying commodity. In this hedge, the change in the value of the hedged inventory is reflected in earnings, which offsets the change in the fair value of the futures contract that is also reflected in earnings. Although the change in the fair value of the hedging instrument recorded in earnings includes changes in forward rates, Citigroup excludes the differential between the spot and the contractual forward rates under the futures contract from the assessment of hedge effectiveness, and it is generally reflected directly in earnings over the life of the hedge. Citi also excludes changes in forward rates from the assessment of hedge effectiveness and records it in Other comprehensive income. The following table summarizes the gains (losses) on the Company’s fair value hedges: Gains (losses) on fair value hedges (1) Three Months Ended March 31, 2022 2021 In millions of dollars Other revenue Net interest income Other revenue Net interest income Gain (loss) on the hedging derivatives included in assessment of the effectiveness of fair value hedges Interest rate hedges $ — $ (4,666) $ — $ (3,935) Foreign exchange hedges (425) — (210) — Commodity hedges 872 — (289) — Total gain (loss) on the hedging derivatives included in assessment of the effectiveness of fair value hedges $ 447 $ (4,666) $ (499) $ (3,935) Gain (loss) on the hedged item in designated and qualifying fair value hedges Interest rate hedges $ — $ 4,597 $ — $ 3,826 Foreign exchange hedges 424 — 210 — Commodity hedges (872) — 289 — Total gain (loss) on the hedged item in designated and qualifying fair value hedges $ (448) $ 4,597 $ 499 $ 3,826 Net gain (loss) on the hedging derivatives excluded from Interest rate hedges $ — $ (6) $ — $ (4) Foreign exchange hedges (2) 31 — 4 — Commodity hedges 49 — (22) — Total net gain (loss) on the hedging derivatives excluded from assessment of the effectiveness of fair value hedges $ 80 $ (6) $ (18) $ (4) (1) Gain (loss) amounts for interest rate risk hedges are included in Interest income/Interest expense . The accrued interest income on fair value hedges is recorded in Net interest income and is excluded from this table. (2) Amounts relate to the premium associated with forward contracts (differential between spot and contractual forward rates) that are excluded from the assessment of hedge effectiveness and are generally reflected directly in earnings. Amounts related to cross-currency basis, which are recognized in AOCI , are not reflected in the table above. The amount of cross-currency basis included in AOCI was $64 million and $(13) million for the three months ended March 31, 2022 and 2021, respectively. Cumulative Basis Adjustment Upon electing to apply ASC 815 fair value hedge accounting, the carrying value of the hedged item is adjusted to reflect the cumulative changes in the hedged risk. This cumulative hedge basis adjustment becomes part of the carrying value of the hedged item until the hedged item is derecognized from the balance sheet. The table below presents the carrying amount of Citi’s hedged assets and liabilities under qualifying fair value hedges at March 31, 2022 and December 31, 2021, along with the cumulative hedge basis adjustments included in the carrying value of those hedged assets and liabilities, that would reverse through earnings in future periods. In millions of dollars Balance sheet line item in which hedged item is recorded Carrying amount of hedged asset/ liability Cumulative fair value hedging adjustment increasing (decreasing) the carrying amount Active De-designated As of March 31, 2022 Debt securities AFS (1)(3) $ 118,112 $ (774) $ (17) Long-term debt 152,347 (4,239) 3,197 As of December 31, 2021 Debt securities AFS (2)(3) $ 62,733 $ 149 $ 212 Long-term debt 149,305 623 3,936 (1) These amounts include a cumulative basis adjustment of $(322) million for active hedges and $(179) million for de-designated hedges as of March 31, 2022, related to certain prepayable financial assets previously designated as the hedged item in a fair value hedge using the last-of-layer approach. The Company designated approximately $8 billion as the hedged amount (from a closed portfolio of prepayable financial assets with a carrying value of $34 billion as of March 31, 2022) in a last-of-layer hedging relationship. (2) These amounts include a cumulative basis adjustment of $24 million for active hedges and $(92) million for de-designated hedges as of December 31, 2021, related to certain prepayable financial assets designated as the hedged item in a fair value hedge using the last-of-layer approach. The Company designated approximately $6 billion as the hedged amount (from a closed portfolio of prepayable financial assets with a carrying value of $25 billion as of December 31, 2021) in a last-of-layer hedging relationship. (3) Carrying amount represents the amortized cost. Cash Flow Hedges Citigroup hedges the variability of forecasted cash flows due to changes in contractually specified interest rates associated with floating-rate assets/liabilities and other forecasted transactions. These cash flow hedging relationships use either regression analysis or dollar-offset ratio analysis to assess whether the hedging relationships are highly effective at inception and on an ongoing basis. For cash flow hedges, the entire change in the fair value of the hedging derivative is recognized in AOCI and then reclassified to earnings in the same period that the forecasted hedged cash flows impact earnings. The net gain (loss) associated with cash flow hedges expected to be reclassified from AOCI within 12 months of March 31, 2022 is approximately $200 million. The maximum length of time over which forecasted cash flows are hedged is 10 years. The pretax change in AOCI from cash flow hedges is presented below. The after-tax impact of cash flow hedges on AOCI is shown in Note 17.

For all other hedges, the amounts reclassified to earnings are included primarily in Other revenue and Net interest income in the Consolidated Statement of Income. Net Investment Hedges The pretax gain (loss) recorded in Foreign currency translation adjustment within AOCI , related to net investment hedges, was ($195) million and $557 million for the three months ended March 31, 2022 and 2021, respectively.

(2) The fair value amount payable is composed of $7,354 million under protection purchased and $3,661 million under protection sold. Credit Risk-Related Contingent Features in Derivatives Certain derivative instruments contain provisions that require the Company to either post additional collateral or immediately settle any outstanding liability balances upon the occurrence of a specified event related to the credit risk of the Company. These events, which are defined by the existing derivative contracts, are primarily downgrades in the credit ratings of the Company and its affiliates. The fair value (excluding CVA) of all derivative instruments with credit risk-related contingent features that were in a net liability position at March 31, 2022 and December 31, 2021 was $19 billion and $19 billion, respectively. The Company posted $16 billion and $16 billion as collateral for this exposure in the normal course of business as of March 31, 2022 and December 31, 2021, respectively. A downgrade could trigger additional collateral or cash settlement requirements for the Company and certain affiliates. In the event that Citigroup and Citibank were downgraded a single notch by all three major rating agencies as of March 31, 2022, the Company could be required to post an additional $1.6 billion as either collateral or settlement of the derivative transactions. In addition, the Company could be required to segregate with third-party custodians collateral previously received from existing derivative counterparties in the amount of $0.1 billion upon the single notch downgrade, resulting in aggregate cash obligations and collateral requirements of approximately $1.7 billion. Derivatives Accompanied by Financial Asset Transfers For transfers of financial assets accounted for as a sale by the Company, and for which the Company has retained substantially all of the economic exposure to the transferred asset through a total return swap executed with the same counterparty in contemplation of the initial sale (and still outstanding), both the asset amounts derecognized and the gross cash proceeds received as of the date of derecognition were $0.8 billion and $2.9 billion as of March 31, 2022 and December 31, 2021, respectively. At March 31, 2022, the fair value of these previously derecognized assets was $0.8 billion. The fair value of the total return swaps as of March 31, 2022 was $30 million recorded as gross derivative assets and $5 million recorded as gross derivative liabilities. At December 31, 2021, the fair value of these previously derecognized assets was $2.9 billion, and the fair value of the total return swaps was $13 million recorded as gross derivative assets and $58 million recorded as gross derivative liabilities. The balances for the total return swaps are on a gross basis, before the application of counterparty and cash collateral netting, and are included primarily as equity derivatives in the tabular disclosures in this Note.

Fair Value Hierarchy ASC 820-10 specifies a hierarchy of inputs based on whether the inputs are observable or unobservable. Observable inputs are developed using market data and reflect market participant assumptions, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs have created the following fair value hierarchy: • Level 1: Quoted prices for identical instruments in active markets. • Level 2: Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations in which all significant inputs and significant value drivers are observable in the market. • Level 3: Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable . As required under the fair value hierarchy, the Company considers relevant and observable market inputs in its valuations where possible. The fair value hierarchy classification approach typically utilizes rules-based and data-driven selection criteria to determine whether an instrument is classified as Level 1, Level 2 or Level 3: • The determination of whether an instrument is quoted in an active market and therefore considered a Level 1 instrument is based upon the frequency of observed transactions and the quality of independent market data available on the measurement date. • A Level 2 classification is assigned where there is observability of prices/market inputs to models, or where any unobservable inputs are not significant to the valuation. The determination of whether an input is considered observable is based on the availability of independent market data and its corroboration, for example through observed transactions in the market. • Otherwise, an instrument is classified as Level 3. Items Measured at Fair Value on a Recurring Basis The following tables present for each of the fair value hierarchy levels the Company’s assets and liabilities that are measured at fair value on a recurring basis at March 31, 2022 and December 31, 2021.

Changes in Level 3 Fair Value Category The following tables present the changes in the Level 3 fair value category for the three months ended March 31, 2022 and 2021. The gains and losses presented below include changes in the fair value related to both observable and unobservable inputs. The Company often hedges positions with offsetting positions that are classified in a different level.

Level 3 Fair Value Rollforward The following were the significant Level 3 transfers for the period December 31, 2021 to March 31, 2022: • During the three months ended March 31, 2022, transfers of Long-term debt were $3.4 billion from Level 2 to Level 3. Of the $3.4 billion transfer in the three months ended March 31, 2022, approximately $2.9 billion related to interest rate option volatility inputs becoming unobservable and/or significant relative to their overall valuation, and $0.5 billion related to equity and credit derivative inputs (in addition to other volatility inputs, e.g., interest rate volatility inputs) becoming unobservable and/or significant to their overall valuation. In other instances, market changes have resulted in some inputs becoming more observable, and some unobservable inputs becoming less significant to the overall valuation of the instruments (e.g., when an option becomes deep-in or deep-out of the money). This has primarily resulted in $0.9 billion of certain structured long-term debt products being transferred from Level 3 to Level 2 during the three months ended March 31, 2022. There were no significant Level 3 transfers for the period December 31, 2020 to March 31, 2021.

Items Measured at Fair Value on a Nonrecurring Basis Certain assets and liabilities are measured at fair value on a nonrecurring basis and, therefore, are not included in the tables above. These include assets measured at cost that have been written down to fair value during the periods as a result of an impairment. These also include non-market

FAIR VALUE ELECTIONS

FAIR VALUE ELECTIONS	3 Months Ended
	Mar. 31, 2022
Fair Value, Option, Aggregate Differences [Abstract]
FAIR VALUE ELECTIONS	FAIR VALUE ELECTIONS The Company may elect to report most financial instruments and certain other items at fair value on an instrument-by-instrument basis with changes in fair value reported in earnings, other than DVA (see below). The election is made upon the initial recognition of an eligible financial asset, financial liability or firm commitment or when certain specified reconsideration events occur. The fair value election may not otherwise be revoked once an election is made. The changes in fair value are recorded in current earnings. Movements in DVA are reported as a component of AOCI . Additional discussion regarding the applicable areas in which fair value elections were made is presented in Note 20. The Company has elected fair value accounting for its mortgage servicing rights (MSRs). See Note 18 for additional details on Citi’s MSRs. The following table presents the changes in fair value of those items for which the fair value option has been elected: Changes in fair value—gains (losses) Three Months Ended March 31, In millions of dollars 2022 2021 Assets Securities borrowed and purchased under agreements to resell $ (62) $ (28) Trading account assets (61) 101 Loans Certain corporate loans (332) 129 Certain consumer loans (1) — Total loans $ (333) $ 129 Other assets MSRs $ 98 $ 73 Certain mortgage loans HFS (1) (186) (3) Total other assets $ (88) $ 70 Total assets $ (544) $ 272 Liabilities Interest-bearing deposits $ 45 $ 37 Securities loaned and sold under agreements to repurchase 77 13 Trading account liabilities (640) 2 Short-term borrowings (2) 132 (135) Long-term debt (2) 6,071 2,008 Total liabilities $ 5,685 $ 1,925 (1) Includes gains (losses) associated with interest rate lock commitments for those loans that have been originated and elected under the fair value option. (2) Includes DVA that is included in AOCI . See Notes 17 and 20. Own Debt Valuation Adjustments (DVA) Own debt valuation adjustments are recognized on Citi’s liabilities for which the fair value option has been elected using Citi’s credit spreads observed in the bond market. Changes in fair value of fair value option liabilities related to changes in Citigroup’s own credit spreads (DVA) are reflected as a component of AOCI . Among other variables, the fair value of liabilities for which the fair value option has been elected (other than non-recourse debt and similar liabilities) is impacted by the narrowing or widening of the Company’s credit spreads. The estimated changes in the fair value of these non-derivative liabilities due to such changes in the Company’s own credit spread (or instrument-specific credit risk) were a gain of $1,050 million and a loss of $38 million for the three months ended March 31, 2022 and 2021, respectively. Changes in fair value resulting from changes in instrument-specific credit risk were estimated by incorporating the Company’s current credit spreads observable in the bond market into the relevant valuation technique used to value each liability as described above. The Fair Value Option for Financial Assets and Financial Liabilities Selected Portfolios of Securities Purchased Under Agreements to Resell, Securities Borrowed, Securities Sold Under Agreements to Repurchase, Securities Loaned and Certain Uncollateralized Short-Term Borrowings The Company elected the fair value option for certain portfolios of fixed income securities purchased under agreements to resell and fixed income securities sold under agreements to repurchase, securities borrowed, securities loaned and certain uncollateralized short-term borrowings held primarily by broker-dealer entities in the United States, the United Kingdom and Japan. In each case, the election was made because the related interest rate risk is managed on a portfolio basis, primarily with offsetting derivative instruments that are accounted for at fair value through earnings. Changes in fair value for transactions in these portfolios are recorded in Principal transactions . The related interest revenue and interest expense are measured based on the contractual rates specified in the transactions and are reported as Interest revenue and Interest expense in the Consolidated Statement of Income. Certain Loans and Other Credit Products Citigroup has also elected the fair value option for certain other originated and purchased loans, including certain unfunded loan products, such as guarantees and letters of credit, executed by Citigroup’s lending and trading businesses. None of these credit products are highly leveraged financing commitments. Significant groups of transactions include loans and unfunded loan products that are expected to be either sold or securitized in the near term, or transactions where the economic risks are hedged with derivative instruments, such as purchased credit default swaps or total return swaps where the Company pays the total return on the underlying loans to a third party. Citigroup has elected the fair value option to mitigate accounting mismatches in cases where hedge accounting is complex and to achieve operational simplifications. Fair value was not elected for most lending transactions across the Company. The following table provides information about certain credit products carried at fair value: March 31, 2022 December 31, 2021 In millions of dollars Trading assets Loans Trading assets Loans Carrying amount reported on the Consolidated Balance Sheet $ 8,798 $ 5,732 $ 9,530 $ 6,082 Aggregate unpaid principal balance in excess of (less than) fair value 113 195 (100) 226 Balance of non-accrual loans or loans more than 90 days past due — 266 — 1 Aggregate unpaid principal balance in excess of (less than) fair value for non-accrual loans or loans more than 90 days past due — — — — In addition to the amounts reported above, $713 million and $719 million of unfunded commitments related to certain credit products selected for fair value accounting were outstanding as of March 31, 2022 and December 31, 2021, respectively. Changes in the fair value of funded and unfunded credit products are classified in Principal transactions in Citi’s Consolidated Statement of Income. Related interest revenue is measured based on the contractual interest rates and reported as Interest revenue on Trading account assets or loan interest depending on the balance sheet classifications of the credit products. The changes in fair value for the three months ended March 31, 2022 and 2021 due to instrument-specific credit risk totaled to losses of $(59) million and $(2) million, respectively. Certain Investments in Unallocated Precious Metals Citigroup invests in unallocated precious metals accounts (gold, silver, platinum and palladium) as part of its commodity and foreign currency trading activities or to economically hedge certain exposures from issuing structured liabilities. Under ASC 815, the investment is bifurcated into a debt host contract and a commodity forward derivative instrument. Citigroup elects the fair value option for the debt host contract, and reports the debt host contract within Trading account assets on the Company’s Consolidated Balance Sheet. The total carrying amount of debt host contracts across unallocated precious metals accounts was approximately $0.3 billion and $0.3 billion at March 31, 2022 and December 31, 2021, respectively. The amounts are expected to fluctuate based on trading activity in future periods. As part of its commodity and foreign currency trading activities, Citi trades unallocated precious metals investments and executes forward purchase and forward sale derivative contracts with trading counterparties. When Citi sells an unallocated precious metals investment, Citi’s receivable from its depository bank is repaid and Citi derecognizes its investment in the unallocated precious metal. The forward purchase or sale contract with the trading counterparty indexed to unallocated precious metals is accounted for as a derivative, at fair value through earnings. As of March 31, 2022, there were approximately $23.6 billion and $14.4 billion of notional amounts of such forward purchase and forward sale derivative contracts outstanding, respectively. Certain Investments in Private Equity and Real Estate Ventures Citigroup invests in private equity and real estate ventures for the purpose of earning investment returns and for capital appreciation. The Company has elected the fair value option for certain of these ventures, because such investments are considered similar to many private equity or hedge fund activities in Citi’s investment companies, which are reported at fair value. The fair value option brings consistency in the accounting and evaluation of these investments. All investments (debt and equity) in such private equity and real estate entities are accounted for at fair value. These investments are classified as Investments on Citigroup’s Consolidated Balance Sheet. Changes in the fair values of these investments are classified in Other revenue in the Company’s Consolidated Statement of Income. Certain Mortgage Loans Held-for-Sale (HFS) Citigroup has elected the fair value option for certain purchased and originated prime fixed-rate and conforming adjustable-rate first mortgage loans HFS. These loans are intended for sale or securitization and are hedged with derivative instruments. The Company has elected the fair value option to mitigate accounting mismatches in cases where hedge accounting is complex and to achieve operational simplifications. The following table provides information about certain mortgage loans HFS carried at fair value: In millions of dollars March 31, December 31, 2021 Carrying amount reported on the Consolidated Balance Sheet $ 2,046 $ 3,035 Aggregate fair value in excess of (less than) unpaid principal balance (64) 70 Balance of non-accrual loans or loans more than 90 days past due — 1 Aggregate unpaid principal balance in excess of fair value for non-accrual loans or loans more than 90 days past due — — The changes in the fair values of these mortgage loans are reported in Other revenue in the Company’s Consolidated Statement of Income. There was no net change in fair value during the three months ended March 31, 2022 and 2021 due to instrument-specific credit risk. Related interest income continues to be measured based on the contractual interest rates and reported as Interest revenue in the Consolidated Statement of Income. Certain Debt Liabilities The Company has elected the fair value option for certain debt liabilities. The Company elected the fair value option because these exposures are considered to be trading-related positions and, therefore, they are managed on a fair value basis. These positions will continue to be classified as debt, deposits or derivatives classified as Trading account liabilities on the Company’s Consolidated Balance Sheet according to their legal form. The following table provides information about the carrying value of notes carried at fair value, disaggregated by type of risk: In billions of dollars March 31, 2022 December 31, 2021 Interest rate linked $ 38.8 $ 38.9 Foreign exchange linked — — Equity linked 36.5 36.1 Commodity linked 4.4 3.9 Credit linked 3.6 3.7 Total $ 83.3 $ 82.6 The portion of the changes in fair value attributable to changes in Citigroup’s own credit spreads (DVA) is reflected as a component of AOCI while all other changes in fair value are reported in Principal transactions . Changes in the fair value of these liabilities include accrued interest, which is also included in the change in fair value reported in Principal transactions . The following table provides information about long-term debt carried at fair value: In millions of dollars March 31, 2022 December 31, 2021 Carrying amount reported on the Consolidated Balance Sheet $ 83,277 $ 82,609 Aggregate unpaid principal balance in excess of (less than) fair value (2,616) (2,459) The following table provides information about short-term borrowings carried at fair value: In millions of dollars March 31, 2022 December 31, 2021 Carrying amount reported on the Consolidated Balance Sheet $ 7,367 $ 7,358 Aggregate unpaid principal balance in excess of (less than) fair value — (644)

Guarantees, Leases And Commitments [Abstract]
GUARANTEES, LEASES AND COMMITMENTS	GUARANTEES, LEASES AND COMMITMENTS Citi provides a variety of guarantees and indemnifications to its customers to enhance their credit standing and enable them to complete a wide variety of business transactions. For certain contracts meeting the definition of a guarantee, the guarantor must recognize, at inception, a liability for the fair value of the obligation undertaken in issuing the guarantee. In addition, the guarantor must disclose the maximum potential amount of future payments that the guarantor could be required to make under the guarantee, if there were a total default by the guaranteed parties. The determination of the maximum potential future payments is based on the notional amount of the guarantees without consideration of possible recoveries under recourse provisions or from collateral held or pledged. As such, Citi believes such amounts bear no relationship to the anticipated losses, if any, on these guarantees. For additional information regarding Citi’s guarantees and indemnifications included in the tables below, as well as its other guarantees and indemnifications excluded from these tables, see Note 26 to the Consolidated Financial Statements in Citi’s 2021 Form 10-K. The following tables present information about Citi’s guarantees at March 31, 2022 and December 31, 2021: Maximum potential amount of future payments In billions of dollars at March 31, 2022 Expire within Expire after Total amount Carrying value (in millions of dollars) Financial standby letters of credit $ 29.8 $ 64.6 $ 94.4 $ 894 Performance guarantees 6.3 6.3 12.6 145 Derivative instruments considered to be guarantees 15.7 41.8 57.5 456 Loans sold with recourse — 1.6 1.6 15 Securities lending indemnifications (1) 128.4 — 128.4 — Credit card merchant processing (2) 111.8 — 111.8 — Credit card arrangements with partners 0.1 0.6 0.7 7 Other 0.6 12.0 12.6 32 Total $ 292.7 $ 126.9 $ 419.6 $ 1,549 Maximum potential amount of future payments In billions of dollars at December 31, 2021 Expire within Expire after Total amount Carrying value ( in millions of dollars) Financial standby letters of credit $ 34.3 $ 58.4 $ 92.7 $ 791 Performance guarantees 6.6 6.4 13.0 47 Derivative instruments considered to be guarantees 14.6 48.9 63.5 514 Loans sold with recourse — 1.7 1.7 15 Securities lending indemnifications (1) 121.9 — 121.9 — Credit card merchant processing (2) 119.4 — 119.4 1 Credit card arrangements with partners — 0.8 0.8 7 Other 2.0 12.0 14.0 34 Total $ 298.8 $ 128.2 $ 427.0 $ 1,409 (1) The carrying values of securities lending indemnifications were not material for either period presented, as the probability of potential liabilities arising from these guarantees is minimal. (2) At March 31, 2022 and December 31, 2021, this maximum potential exposure was estimated to be $112 billion and $119 billion, respectively. However, Citi believes that the maximum exposure is not representative of the actual potential loss exposure based on its historical experience. This contingent liability is unlikely to arise, as most products and services are delivered when purchased and amounts are refunded when items are returned to merchants. Loans Sold with Recourse Loans sold with recourse represent Citi’s obligations to reimburse the buyers for loan losses under certain circumstances. Recourse refers to the clause in a sales agreement under which a seller/lender will fully reimburse the buyer/investor for any losses resulting from the purchased loans. This may be accomplished by the sellers taking back any loans that become delinquent. In addition to the amounts shown in the tables above, Citi has recorded a repurchase reserve for its potential repurchases or make-whole liability regarding residential mortgage representation and warranty claims related to its whole loan sales to U.S. government-sponsored agencies and, to a lesser extent, private investors. The repurchase reserve was approximately $18 million and $19 million at March 31, 2022 and December 31, 2021, respectively, and these amounts are included in Other liabilities on the Consolidated Balance Sheet. Credit Card Arrangements with Partners Citi, in one of its credit card partner arrangements, provides guarantees to the partner regarding the volume of certain customer originations during the term of the agreement. To the extent that such origination targets are not met, the guarantees serve to compensate the partner for certain payments that otherwise would have been generated in connection with such originations. Other Guarantees and Indemnifications Credit Card Protection Programs Citi, through its credit card businesses, provides various cardholder protection programs on several of its card products, including programs that provide insurance coverage for rental cars, coverage for certain losses associated with purchased products, price protection for certain purchases and protection for lost luggage. These guarantees are not included in the table, since the total outstanding amount of the guarantees and Citi’s maximum exposure to loss cannot be quantified. The protection is limited to certain types of purchases and losses, and it is not possible to quantify the purchases that would qualify for these benefits at any given time. Citi assesses the probability and amount of its potential liability related to these programs based on the extent and nature of its historical loss experience. At March 31, 2022 and December 31, 2021, the actual and estimated losses incurred and the carrying value of Citi’s obligations related to these programs were immaterial. Value-Transfer Networks (Including Exchanges and Clearing Houses) (VTNs) Citi is a member of, or shareholder in, hundreds of value-transfer networks (VTNs) (payment, clearing and settlement systems as well as exchanges) around the world. As a condition of membership, many of these VTNs require that members stand ready to pay a pro rata share of the losses incurred by the organization due to another member’s default on its obligations. Citi’s potential obligations may be limited to its membership interests in the VTNs, contributions to the VTN’s funds, or, in certain narrow cases, to the full pro rata share. The maximum exposure is difficult to estimate as this would require an assessment of claims that have not yet occurred; however, Citi believes the risk of loss is remote given historical experience with the VTNs. Accordingly, Citi’s participation in VTNs is not reported in the guarantees tables above, and there are no amounts reflected on the Consolidated Balance Sheet as of March 31, 2022 or December 31, 2021 for potential obligations that could arise from Citi’s involvement with VTN associations. Long-Term Care Insurance Indemnification Through reinsurance agreements and a long-term care indemnification with Genworth Financial Inc. for what are presently referred to as the Genworth Trusts, and only as a result of two unlikely events, Citi would be responsible for an indemnification obligation. Since the likelihood of such events occurring is currently not probable, there is no liability reflected on the Consolidated Balance Sheet as of March 31, 2022 and December 31, 2021 related to this indemnification. However, if both events become reasonably possible (meaning more than remote but less than probable), Citi will be required to estimate and disclose a reasonably possible loss or range of loss to the extent that such an estimate could be made. In addition, if both events become probable, Citi will be required to accrue for such liability in accordance with applicable accounting principles. Citi continues to closely monitor its potential exposure under this indemnification obligation. For additional information, see Note 26 to the Consolidated Financial Statements in Citi’s 2021 Form 10-K. Futures and Over-the-Counter Derivatives Clearing Citi provides clearing services on central clearing parties (CCP) for clients that need to clear exchange-traded and over-the-counter (OTC) derivative contracts with CCPs. Based on all relevant facts and circumstances, Citi has concluded that it acts as an agent for accounting purposes in its role as clearing member for these client transactions. As such, Citi does not reflect the underlying exchange-traded or OTC derivatives contracts in its Consolidated Financial Statements. See Note 19 for a discussion of Citi’s derivatives activities that are reflected in its Consolidated Financial Statements. As a clearing member, Citi collects and remits cash and securities collateral (margin) between its clients and the respective CCP. In certain circumstances, Citi collects a higher amount of cash (or securities) from its clients than it needs to remit to the CCPs. This excess cash is then held at depository institutions such as banks or carry brokers. There are two types of margin: initial and variation. Where Citi obtains benefits from or controls cash initial margin (e.g., retains an interest spread), cash initial margin collected from clients and remitted to the CCP or depository institutions is reflected within Brokerage payables (payables to customers) and Brokerage receivables (receivables from brokers, dealers and clearing organizations) or Cash and due from banks , respectively. However, for exchange-traded and OTC-cleared derivative contracts where Citi does not obtain benefits from or control the client cash balances, the client cash initial margin collected from clients and remitted to the CCP or depository institutions is not reflected on Citi’s Consolidated Balance Sheet. These conditions are met when Citi has contractually agreed with the client that (i) Citi will pass through to the client all interest paid by the CCP or depository institutions on the cash initial margin, (ii) Citi will not utilize its right as a clearing member to transform cash margin into other assets, (iii) Citi does not guarantee and is not liable to the client for the performance of the CCP or the depository institution and (iv) the client cash balances are legally isolated from Citi’s bankruptcy estate. The total amount of cash initial margin collected and remitted in this manner was approximately $19.8 billion and $18.7 billion as of March 31, 2022 and December 31, 2021, respectively. Variation margin due from clients to the respective CCP, or from the CCP to clients, reflects changes in the value of the client’s derivative contracts for each trading day. As a clearing member, Citi is exposed to the risk of non-performance by clients (e.g., failure of a client to post variation margin to the CCP for negative changes in the value of the client’s derivative contracts). In the event of non-performance by a client, Citi would move to close out the client’s positions. The CCP would typically utilize initial margin posted by the client and held by the CCP, with any remaining shortfalls required to be paid by Citi as clearing member. Citi generally holds incremental cash or securities margin posted by the client, which would typically be expected to be sufficient to mitigate Citi’s credit risk in the event the client fails to perform. As required by ASC 860-30-25-5, securities collateral posted by clients is not recognized on Citi’s Consolidated Balance Sheet. Carrying Value—Guarantees and Indemnifications At March 31, 2022 and December 31, 2021, the total carrying amounts of the liabilities related to the guarantees and indemnifications included in the tables above amounted to approximately $1.5 billion and $1.4 billion, respectively. The carrying value of financial and performance guarantees is included in Other liabilities . For loans sold with recourse, the carrying value of the liability is included in Other liabilities . Collateral Cash collateral available to Citi to reimburse losses realized under these guarantees and indemnifications amounted to $62.9 billion and $56.5 billion at March 31, 2022 and December 31, 2021, respectively. Securities and other marketable assets held as collateral amounted to $85.3 billion and $84.2 billion at March 31, 2022 and December 31, 2021, respectively. The majority of collateral is held to reimburse losses realized under securities lending indemnifications. In addition, letters of credit in favor of Citi held as collateral amounted to $3.8 billion and $4.1 billion at March 31, 2022 and December 31, 2021, respectively. Other property may also be available to Citi to cover losses under certain guarantees and indemnifications; however, the value of such property has not been determined. Performance Risk Presented in the tables below are the maximum potential amounts of future payments that are classified based on internal and external credit ratings. The determination of the maximum potential future payments is based on the notional amount of the guarantees without consideration of possible recoveries under recourse provisions or from collateral held or pledged. As such, Citi believes such amounts bear no relationship to the anticipated losses, if any, on these guarantees. Maximum potential amount of future payments In billions of dollars at March 31, 2022 Investment Non-investment Not Total Financial standby letters of credit $ 81.9 $ 11.1 $ 1.4 $ 94.4 Performance guarantees 10.0 2.6 — 12.6 Derivative instruments deemed to be guarantees — — 57.5 57.5 Loans sold with recourse — — 1.6 1.6 Securities lending indemnifications — — 128.4 128.4 Credit card merchant processing — — 111.8 111.8 Credit card arrangements with partners — — 0.7 0.7 Other 0.3 12.3 — 12.6 Total $ 92.2 $ 26.0 $ 301.4 $ 419.6 Maximum potential amount of future payments In billions of dollars at December 31, 2021 Investment Non-investment Not Total Financial standby letters of credit $ 81.4 $ 11.3 $ — $ 92.7 Performance guarantees 10.5 2.5 — 13.0 Derivative instruments deemed to be guarantees — — 63.5 63.5 Loans sold with recourse — — 1.7 1.7 Securities lending indemnifications — — 121.9 121.9 Credit card merchant processing — — 119.4 119.4 Credit card arrangements with partners — — 0.8 0.8 Other 1.7 12.3 — 14.0 Total $ 93.6 $ 26.1 $ 307.3 $ 427.0 Leases The Company’s operating leases, where Citi is a lessee, include real estate such as office space and branches and various types of equipment. These leases have a weighted-average remaining lease term of approximately six years as of March 31, 2022. The operating lease ROU asset and lease liability were $2.9 billion and $3.1 billion, respectively, as of March 31, 2022, compared to an operating lease ROU asset of $2.9 billion and lease liability of $3.1 billion as of December 31, 2021. The Company recognizes fixed lease costs on a straight-line basis throughout the lease term in the Consolidated Statement of Income. In addition, variable lease costs are recognized in the period in which the obligation for those payments is incurred. Credit Commitments and Lines of Credit The table below summarizes Citigroup’s credit commitments: In millions of dollars U.S. Outside of March 31, December 31, Commercial and similar letters of credit $ 830 $ 5,988 $ 6,818 $ 5,910 One- to four-family residential mortgages 1,855 2,575 4,430 4,351 Revolving open-end loans secured by one- to four-family residential properties 6,564 1,112 7,676 7,913 Commercial real estate, construction and land development 13,073 1,940 15,013 17,843 Credit card lines 606,384 100,703 707,087 700,559 Commercial and other consumer loan commitments 211,495 109,749 321,244 320,556 Other commitments and contingencies 5,655 215 5,870 5,649 Total $ 845,856 $ 222,282 $ 1,068,138 $ 1,062,781 The majority of unused commitments are contingent upon customers maintaining specific credit standards. Commercial commitments generally have floating interest rates and fixed expiration dates and may require payment of fees. Such fees (net of certain direct costs) are deferred and, upon exercise of the commitment, amortized over the life of the loan or, if exercise is deemed remote, amortized over the commitment period. Other Commitments and Contingencies Other commitments and contingencies include all other transactions related to commitments and contingencies not reported on the lines above. Unsettled Reverse Repurchase and Securities Borrowing Agreements and Unsettled Repurchase and Securities Lending Agreements In addition, in the normal course of business, Citigroup enters into reverse repurchase and securities borrowing agreements, as well as repurchase and securities lending agreements, which settle at a future date. At March 31, 2022 and December 31, 2021, Citigroup had approximately $153.0 billion and $126.6 billion of unsettled reverse repurchase and securities borrowing agreements, and approximately $48.6 billion and $41.1 billion of unsettled repurchase and securities lending agreements, respectively. See Note 10 for a further discussion of securities purchased under agreements to resell and securities borrowed, and securities sold under agreements to repurchase and securities loaned, including the Company’s policy for offsetting repurchase and reverse repurchase agreements. Restricted Cash Citigroup defines restricted cash (as cash subject to withdrawal restrictions) to include cash deposited with central banks that must be maintained to meet minimum regulatory requirements, and cash set aside for the benefit of customers or for other purposes such as compensating balance arrangements or debt retirement. Restricted cash includes minimum reserve requirements with the Federal Reserve Bank and certain other central banks and cash segregated to satisfy rules regarding the protection of customer assets as required by Citigroup broker-dealers’ primary regulators, including the United States Securities and Exchange Commission (SEC), the Commodity Futures Trading Commission and the United Kingdom’s Prudential Regulation Authority. Restricted cash is included on the Consolidated Balance Sheet within the following balance sheet lines: In millions of dollars March 31, December 31, Cash and due from banks $ 3,417 $ 2,786 Deposits with banks, net of allowance 15,191 10,636 Total $ 18,608 $ 13,422 In response to the COVID-19 pandemic, the Federal Reserve Bank and certain other central banks eased regulations related to minimum required cash deposited with central banks.

Commitments and Contingencies Disclosure [Abstract]
CONTINGENCIES	CONTINGENCIES The following information supplements and amends, as applicable, the disclosure in Note 27 to the Consolidated Financial Statements in Citi’s 2021 Form 10-K. For purposes of this Note, Citigroup, its affiliates and subsidiaries and current and former officers, directors, and employees, are sometimes collectively referred to as Citigroup and Related Parties. In accordance with ASC 450, Citigroup establishes accruals for contingencies, including any litigation, regulatory, or tax matters disclosed herein, when Citigroup believes it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. Once established, accruals are adjusted from time to time, as appropriate, in light of additional information. The amount of loss ultimately incurred in relation to those matters may be substantially higher or lower than the amounts accrued for those matters. If Citigroup has not accrued for a matter because the matter does not meet the criteria for accrual (as set forth above), or Citigroup believes an exposure to loss exists in excess of the amount accrued for a particular matter, in each case assuming a material loss is reasonably possible but not probable, Citigroup discloses the matter. In addition, for such matters, Citigroup discloses an estimate of the aggregate reasonably possible loss or range of loss in excess of the amounts accrued for those matters for which an estimate can be made. At March 31, 2022, Citigroup estimates that the reasonably possible unaccrued loss for these matters ranges up to approximately $1.4 billion in the aggregate. As available information changes, the matters for which Citigroup is able to estimate will change, and the estimates themselves will change. In addition, while many estimates presented in financial statements and other financial disclosures involve significant judgment and may be subject to significant uncertainty, estimates of the range of reasonably possible loss arising from litigation, regulatory, tax, or other matters are subject to particular uncertainties. For example, at the time of making an estimate, Citigroup may only have preliminary or incomplete information about the facts underlying the claim; its assumptions about the future rulings of the court or other tribunal on significant issues, or the behavior and incentives of adverse parties, regulators, or tax authorities may prove to be wrong; and the outcomes it is attempting to predict are often not amenable to the use of statistical or other quantitative analytical tools. In addition, from time to time an outcome may occur that Citigroup had not accounted for in its estimates because it had deemed such an outcome to be remote. For all these reasons, the amount of loss in excess of amounts accrued in relation to matters for which an estimate has been made could be substantially higher or lower than the range of loss included in the estimate. Subject to the foregoing, it is the opinion of Citigroup’s management, based on current knowledge and after taking into account its current accruals, that the eventual outcome of all matters described in this Note would not be likely to have a material adverse effect on the consolidated financial condition of Citigroup. Nonetheless, given the substantial or indeterminate amounts sought in certain of these matters and the inherent unpredictability of such matters, an adverse outcome in certain of these matters could, from time to time, have a material adverse effect on Citigroup’s consolidated results of operations or cash flows in particular quarterly or annual periods. For further information on ASC 450 and Citigroup’s accounting and disclosure framework for contingencies, including for any litigation, regulatory, and tax matters disclosed herein, see Note 27 to the Consolidated Financial Statements in Citi’s 2021 Form 10-K.

BASIS OF PRESENTATION, UPDATE_2

BASIS OF PRESENTATION, UPDATED ACCOUNTING POLICIES AND ACCOUNTING CHANGES (Policies)	3 Months Ended
	Mar. 31, 2022
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited Consolidated Financial Statements as of March 31, 2022 and for the three-month periods ended March 31, 2022 and 2021 include the accounts of Citigroup Inc. and its consolidated subsidiaries. In the opinion of management, all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation have been reflected. The accompanying unaudited Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and related notes included in Citigroup’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021 (2021 Form 10-K). Certain financial information that is normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP), but is not required for interim reporting purposes, has been condensed or omitted. Management must make estimates and assumptions that affect the Consolidated Financial Statements and the related footnote disclosures. While management uses its best judgment, actual results could differ from those estimates. As noted above, the Notes to these Consolidated Financial Statements are unaudited. Throughout these Notes, “Citigroup,” “Citi” and “the Company” refer to Citigroup Inc. and its consolidated subsidiaries. Certain reclassifications and updates have been made to the prior periods’ financial statements and notes to conform to the current period’s presentation.
Summary of Significant Accounting Policies and Accounting Changes	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES See Note 1 to the Consolidated Financial Statements in Citigroup’s 2021 Form 10-K for a summary of all of Citigroup’s significant accounting policies. ACCOUNTING CHANGES Accounting for Deposit Insurance Expenses During the fourth quarter of 2021, Citi changed its presentation of accounting for deposit insurance costs paid to the Federal Deposit Insurance Corporation (FDIC) and similar foreign regulators. These costs were previously presented within Interest expense and, as a result of this change, are now presented within Other operating expenses . Citi concluded that this presentation was preferable in Citi’s circumstances, as it better reflected the nature of these deposit insurance costs in that these costs do not directly represent interest payments to creditors, but are similar in nature to other payments to regulatory agencies that are accounted for as operating expenses. This change in income statement presentation represents a “change in accounting principle” under ASC Topic 250, Accounting Changes and Error Corrections , with retrospective application to the earliest period presented. This change in accounting principle resulted in a reclassification of $340 million of deposit insurance expenses from Interest expense to Other operating expenses , for the quarter ended March 31, 2021. This change had no impact on Citi’s net income or the total deposit insurance expense incurred by Citi. FUTURE ACCOUNTING CHANGES Obligations to Safeguard Crypto-assets Held for Platform Users In March 2022, the SEC issued Staff Accounting Bulletin (SAB) No. 121, which expresses the views of the SEC staff regarding the accounting for obligations to safeguard crypto-assets an entity holds for platform users. Specifically, the guidance requires issuers that hold digital assets for their platform users to recognize a liability for their obligation to safeguard the digital assets held and a corresponding asset, measured initially and subsequently at fair value. The guidance is effective for interim and annual periods ending after June 15, 2022, with retrospective application to the beginning of the fiscal year, with early adoption permitted. Citi is currently assessing the application of SAB 121, but based on its current activity does not expect any impact to its results of operations as a result of adopting SAB 121. Fair Value Hedging—Portfolio Layer Method In March 2022, the FASB issued ASU No. 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method , intended to better align hedge accounting with an organization’s risk management strategies. Specifically, the guidance expands the current single-layer method to allow multiple hedge layers of a single closed portfolio of qualifying assets, which include both prepayable and non-prepayable assets. Upon the adoption of the guidance, entities may elect to reclassify securities held-to-maturity to the available-for-sale category as long as the reclassified securities are designated in a portfolio hedge. The guidance is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years with early adoption permitted. Citi is evaluating when to adopt the amendments in ASU 2022-01. Citi does not expect a material impact to its results of operations as a result of adopting the amendments. Troubled Debt Restructurings and Vintage Disclosures In March 2022, the FASB issued ASU No. 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures . The ASU eliminates the accounting guidance for troubled debt restructurings by creditors, enhances disclosure requirements for certain loan refinancings and restructurings by creditors and requires that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20. The guidance is effective beginning January 1, 2023 and early adoption is permitted. Citi is evaluating whether to early adopt and the effect that ASU 2022-02 will have on its Consolidated Financial Statements and related disclosures. Long-Duration Insurance Contracts In August 2018, the FASB issued ASU No. 2018-12, Financial Services—Insurance: Targeted Improvements to the Accounting for Long-Duration Contracts , which changes the existing recognition, measurement, presentation and disclosures for long-duration contracts issued by an insurance entity. Specifically, the guidance (i) improves the timeliness of recognizing changes in the liability for future policy benefits and prescribes the rate used to discount future cash flows for long-duration insurance contracts, (ii) simplifies and improves the accounting for certain market-based options or guarantees associated with deposit (or account balance) contracts, (iii) simplifies the amortization of deferred acquisition costs and (iv) introduces additional quantitative and qualitative disclosures. Citi has certain insurance subsidiaries, primarily in Mexico, that issue long-duration insurance contracts such as traditional life insurance policies and life-contingent annuity contracts that will be impacted by the requirements of ASU 2018-12. The effective date of ASU 2018-12 was deferred for all insurance entities by ASU 2019-09, Financial Services—Insurance: Effective Date (issued in October 2019) and by ASU 2020-11, Financial Services—Insurance: Effective Date and Early Application (issued in November 2020). Citi plans to adopt the targeted improvements in ASU 2018-12 on January 1, 2023 and is currently evaluating the impact of the standard on its insurance subsidiaries. Citi does not expect a material impact to its results of operations as a result of adopting the standard.

For Australia, excludes the pretax loss on sale. (2) Loans, net of allowance as of March 31, 2022: Australia $145 million, Philippines $71 million, Thailand $71 million, Taiwan $66 million and India $69 million. (3) For Australia, includes intangible assets. (4) Beginning in the third quarter of 2021, Citi reported the business as HFS. In the third and fourth quarters of 2021, Citi recognized an aggregate pretax loss on sale of approximately $700 million ($600 million after-tax), subject to closing adjustments. The loss on sale primarily reflects the impact of a pretax $625 million currency translation adjustment (CTA) loss (net of hedges) ($475 million after-tax) already reflected in the Accumulated other comprehensive income (AOCI) component of equity. Upon closing, the CTA-related balance will be removed from the AOCI component of equity, resulting in a neutral CTA impact to Citi’s Common Equity Tier 1 Capital. In the first quarter of 2022, Citi recorded an additional pretax loss on sale of approximately $118 million recorded in Other revenue ($81 million after-tax), primarily reflecting the impact of a pretax ACL release of $104 million and contractual adjustments of $14 million. (5) These sales are expected to result in an after-tax gain upon closing.

These agreements are subject to contractually based performance thresholds that, if met, would require Citi to make ongoing payments to the partner. The threshold is based on the profitability of a program and is generally calculated based on predefined program revenues less predefined program expenses. In most of Citi’s partner-sharing agreements, program expenses include net credit losses and, to the extent that the increase in net credit losses reduces Citi’s liability for the partners’ share for a given program year, would generally result in lower payments to partners in total for that year and vice versa. Further, in some instances, other partner payments are based on program sales and new account acquisitions.

(2) Gains due to settlement and curtailment relate to divestiture activities. (3) The U.S. qualified pension plan is fully funded under specified Employee Retirement Income Security Act of 1974, as amended (ERISA), funding rules as of January 1, 2022 and no minimum required funding is expected for 2022. (4) The nonqualified plans of the Company are unfunded. (5) The framework for the Company’s pension oversight process includes monitoring of potential settlement charges for all plans. Settlement accounting is triggered when either the sum of all settlements (including lump sum payments) for the year is greater than service plus interest costs or if more than 10% of the plan’s projected benefit obligation will be settled. Because some of Citi’s significant plans are frozen and have no material service cost, settlement accounting may apply in the future.

(2) Company contributions are composed of cash contributions made to the plans and benefits paid directly by the Company. (3) Estimated 2022 benefit payments have increased due to the wind-down of Citi’s consumer banking business in Korea, as it is expected that employees who elected the VERP will be withdrawing their pension plan assets. See Note 2 for additional information.

(2) TDRs involving changes in the amount or timing of principal payments may involve principal forgiveness or deferral of periodic and/or final principal payments. Because forgiveness of principal is rare for corporate loans, modifications typically have little to no impact on the loans’ projected cash flows and thus little to no impact on the allowance established for the loans. Charge-offs for amounts deemed uncollectible may be recorded at the time of the restructuring or may have already been recorded in prior periods such that no charge-off is required at the time of the modification. (3) TDRs involving changes in the amount or timing of interest payments may involve a below-market interest rate.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative notionals	Information pertaining to Citigroup’s derivatives activities, based on notional amounts, is presented in the table below. Derivative notional amounts are reference amounts from which contractual payments are derived and do not represent a complete measure of Citi’s exposure to derivative transactions. Citi’s derivative exposure arises primarily from market fluctuations (i.e., market risk), counterparty failure (i.e., credit risk) and/or periods of high volatility or financial stress (i.e., liquidity risk), as well as any market valuation adjustments that may be required on the transactions. Moreover, notional amounts do not reflect the netting of offsetting trades. For example, if Citi enters into a receive-fixed interest rate swap with $100 million notional, and offsets this risk with an identical but opposite pay-fixed position with a different counterparty, $200 million in derivative notionals is reported, although these offsetting positions may result in de minimis overall market risk. In addition, aggregate derivative notional amounts can fluctuate from period to period in the normal course of business based on Citi’s market share, levels of client activity and other factors.

These arrangements allow a protection seller to assume the credit risk associated with the reference asset without directly purchasing that asset. The Company enters into credit derivative positions for purposes such as risk management, yield enhancement, reduction of credit concentrations and diversification of overall risk.
Derivative mark-to-market (MTM) receivables/payables	The following tables present the gross and net fair values of the Company’s derivative transactions and the related offsetting amounts as of March 31, 2022 and December 31, 2021. Gross positive fair values are offset against gross negative fair values by counterparty, pursuant to enforceable master netting agreements. Under ASC 815-10-45, payables and receivables in respect of cash collateral received from or paid to a given counterparty pursuant to a credit support annex are included in the offsetting amount if a legal opinion supporting the enforceability of netting and collateral rights has been obtained. GAAP does not permit similar offsetting for security collateral. In addition, the following tables reflect rule changes adopted by clearing organizations that require or allow entities to treat certain derivative assets, liabilities and the related variation margin as settlement of the related derivative fair values for legal and accounting purposes, as opposed to presenting gross derivative assets and liabilities that are subject to collateral, whereby the counterparties would also record a related collateral payable or receivable. As a result, the tables reflect a reduction of approximately $430 billion and $340 billion as of March 31, 2022 and December 31, 2021, respectively, of derivative assets and derivative liabilities that previously would have been reported on a gross basis, but are now legally settled and not subject to collateral. The tables also present amounts that are not permitted to be offset, such as security collateral or cash collateral posted at third-party custodians, but which would be eligible for offsetting to the extent that an event of default has occurred and a legal opinion supporting enforceability of the netting and collateral rights has been obtained.

Guarantees, Leases And Commitments [Abstract]
Schedule of guarantor obligations	The following tables present information about Citi’s guarantees at March 31, 2022 and December 31, 2021: Maximum potential amount of future payments In billions of dollars at March 31, 2022 Expire within Expire after Total amount Carrying value (in millions of dollars) Financial standby letters of credit $ 29.8 $ 64.6 $ 94.4 $ 894 Performance guarantees 6.3 6.3 12.6 145 Derivative instruments considered to be guarantees 15.7 41.8 57.5 456 Loans sold with recourse — 1.6 1.6 15 Securities lending indemnifications (1) 128.4 — 128.4 — Credit card merchant processing (2) 111.8 — 111.8 — Credit card arrangements with partners 0.1 0.6 0.7 7 Other 0.6 12.0 12.6 32 Total $ 292.7 $ 126.9 $ 419.6 $ 1,549 Maximum potential amount of future payments In billions of dollars at December 31, 2021 Expire within Expire after Total amount Carrying value ( in millions of dollars) Financial standby letters of credit $ 34.3 $ 58.4 $ 92.7 $ 791 Performance guarantees 6.6 6.4 13.0 47 Derivative instruments considered to be guarantees 14.6 48.9 63.5 514 Loans sold with recourse — 1.7 1.7 15 Securities lending indemnifications (1) 121.9 — 121.9 — Credit card merchant processing (2) 119.4 — 119.4 1 Credit card arrangements with partners — 0.8 0.8 7 Other 2.0 12.0 14.0 34 Total $ 298.8 $ 128.2 $ 427.0 $ 1,409 (1) The carrying values of securities lending indemnifications were not material for either period presented, as the probability of potential liabilities arising from these guarantees is minimal. (2) At March 31, 2022 and December 31, 2021, this maximum potential exposure was estimated to be $112 billion and $119 billion, respectively. However, Citi believes that the maximum exposure is not representative of the actual potential loss exposure based on its historical experience. This contingent liability is unlikely to arise, as most products and services are delivered when purchased and amounts are refunded when items are returned to merchants.
Schedule of guarantor obligations by credit ratings	Presented in the tables below are the maximum potential amounts of future payments that are classified based on internal and external credit ratings. The determination of the maximum potential future payments is based on the notional amount of the guarantees without consideration of possible recoveries under recourse provisions or from collateral held or pledged. As such, Citi believes such amounts bear no relationship to the anticipated losses, if any, on these guarantees.
