The Office of the Comptroller of the Currency (OCC) is amending its capital adequacy rules with respect to deferred tax assets. This final rule limits the amount of certain deferred tax assets that a bank may include in Tier 1 capital for risk-based capital and leverage capital purposes. The OCC, in consultation with the Board of Governors of the Federal Reserve System (FRB), the Federal Deposit Insurance Corporation (FDIC), and the Office of the Thrift Supervision (OTS) (banking agencies), developed this final rule in response to the Financial Accounting Standards Board's (FASB) issuance of Statement of Financial Accounting Standards No. 109, ``Accounting for Income Taxes'' (FAS 109), in February 1992. The banking agencies adopted the provisions of FAS 109 for reporting in quarterly Consolidated Reports of Condition and Income (Call Reports) beginning January 1, 1993. This reporting change increased the amount of net deferred tax assets that a bank may record on its balance sheet. This final rule will ensure that national banks do not place excessive reliance on deferred tax assets to satisfy the minimum capital adequacy requirements.
