The FDIC is adopting a final rule to facilitate prompt payment of FDIC-insured deposits when large insured depository institutions fail. The final rule requires each insured depository institution that has two million or more deposit accounts to (1) configure its information technology system to be capable of calculating the insured and uninsured amount in each deposit account by ownership right and capacity, which would be used by the FDIC to make deposit insurance determinations in the event of the institution's failure, and (2) maintain complete and accurate information needed by the FDIC to determine deposit insurance coverage with respect to each deposit account, except as otherwise provided.
