The Office of the Comptroller of the Currency, the Board of Governors of the Federal Reserve System, and the Federal Deposit Insurance Corporation (collectively, the Agencies) invited public comment on a joint proposal to address changes to U.S. generally accepted accounting principles (U.S. GAAP) described in Accounting Standards Update No. 201613, Topic 326, Financial Instruments Credit Losses (ASU 201613), including banking organizations’ implementation of the current expected credit losses methodology. Specifically, the proposal would revise the Agencies’ regulatory capital rules to identify which credit loss allowances under the new accounting standard are eligible for inclusion in regulatory capital and to provide banking organizations the option to phase in the day-one adverse effects on regulatory capital that may result from the adoption of the new accounting standard. The proposal also would amend certain regulatory disclosure requirements to reflect applicable changes to U.S. GAAP covered under ASU 201613. In addition, the agencies are proposing to make amendments to their stress testing regulations so that covered banking organizations that have adopted ASU 201613 would not include the effect of ASU 201613 on their provisioning for purposes of stress testing until the 2020 stress test cycle. Finally, the agencies are proposing to make conforming amendments to their other regulations that reference credit loss allowances.
