What is CECL in accounting?

CECL is the U.S. GAAP accounting standard codified in FASB ASC 326 (introduced by ASU 2016-13). It requires entities to recognize an allowance equal to the lifetime expected credit losses on financial assets carried at amortized cost — loans, held-to-maturity securities, trade receivables and off-balance-sheet credit exposures.

January 1, 2020 for SEC-registered large filers; January 1, 2023 for all other entities including community banks and credit unions.
