ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Assets Measured at Amortized Cost.” (modified by ASU 2018-19, ASU 2019-04 and ASU 2019-05). ASU 2016-13 requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates and affects loans, debt securities, trade receivables, off-balance-sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. For SEC filers that are not smaller reporting companies, the amendments in this update are effective for the fiscal years beginning after December 15, 2019, including interim periods within those fiscal years.

In December 2018, the OCC, the Board of Governors of the Federal Reserve System, and the FDIC approved a final rule to address changes to credit loss accounting under GAAP, including banking organizations’ implementation of ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“CECL”). Under the CARES Act, the effective date for the implementation of ASU No. 2016-13 was delayed until the earlier of the end of the health crises caused by the COVID-19 Pandemic or December 31, 2020. The Economic Aid Act then further delayed implementation until the earlier of the end of the health crises caused by the COVID-19 Pandemic or December 31, 2022.

The Company is adopting Topic 326, as of January 1, 2021. While the Company has not finalized the impact of implementing CECL, the Company expects to recognize a one-time cumulative effect adjustment to the allowance and beginning retained earnings, net of tax, upon adoption. The future impact of CECL on the Company’s allowance for credit losses and provision expense subsequent to the initial adoption will depend on changes in the loan portfolio, economic conditions and refinements to key assumptions including forecasting and qualitative factors. The Company measured its allowance under its current incurred loan loss model as of December 31, 2020.
