(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 December 31, 2023 and 2022, this maximum potential exposure was estimated to be approximately $138 billion and $130 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.

(3)Includes guarantees to the Fixed Income Clearing Corporation under the sponsored member repo program.

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.

	Maximum potential amount of future payments
In billions of dollars at December 31, 2023	Investment grade		Non-investment grade		Not rated		Total
Financial standby letters of credit	$	70.5	$	10.8	$	—	$	81.3
