Commitments and Contingencies Disclosure [Abstract]
CONTINGENCIES	CONTINGENCIES The following information supplements and amends, as applicable, the disclosure in Note 23 to the Consolidated Financial Statements of Citigroup’s First Quarter of 2019 Form 10-Q and Note 27 to the Consolidated Financial Statements of Citigroup’s 2018 Annual Report on 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 the litigation, regulatory, and 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, 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 as to which an estimate can be made. At June 30, 2019, Citigroup’s estimate of the reasonably possible unaccrued loss for these matters was approximately $1.2 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 have only preliminary, incomplete, or inaccurate 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 accruals ultimately incurred for the matters as to 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 legal 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 the litigation, regulatory, and tax matters disclosed herein, see Note 27 to the Consolidated Financial Statements of Citigroup’s 2018 Annual Report on Form 10-K.
