(2)Unrealized gains and losses are recognized in earnings.
(3)Includes $41 million and $37 million of investments in funds for which the fair values are estimated using the net asset value of the Company’s ownership interest in the funds at March 31, 2026 and December 31, 2025, respectively.
(4)Impairment losses and adjustments to the carrying value as a result of observable price changes are recognized in earnings. See “Non-Marketable Equity Securities Not Carried at Fair Value” below.
(5)    Represents shares issued by the Federal Reserve Bank, Federal Home Loan Banks and certain exchanges of which Citigroup is a member.
(6)    Not included in the balances above is approximately $2 billion of accrued interest receivable at March 31, 2026 and December 31, 2025, which is included in Other assets on the Consolidated Balance Sheet. The Company does not recognize an allowance for credit losses on accrued interest receivable for AFS and HTM debt securities, consistent with its non-accrual policy, which results in timely write-off of accrued interest. The Company did not reverse through interest income any accrued interest receivables for the quarters ended March 31, 2026 and 2025.
