New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Pronouncements	Recent Accounting Pronouncements Adopted in 2019 In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842). ASU No. 2016-02 requires lessees to recognize on the balance sheet the assets and liabilities arising from operating leases. In July 2018, FASB issued ASU No. 2018-11, Leases (Topic 842) to address the comparative reporting requirements when this ASU is adopted. In March 2019, FASB issued ASU 2019-01, Leases (Topic 842), Codification Improvements. Under these ASUs, a lessee should recognize a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. A lessee should include payments to be made in an optional period only if the lessee is reasonably certain to exercise an option to extend the lease or not to exercise an option to terminate the lease. For a finance lease, interest payments should be recognized separately from amortization of the right-of-use asset in the statement of comprehensive income. For operating leases, the lease cost should be allocated over the lease term on a generally straight-line basis. The Company adopted this ASU on January 1, 2019 and according to ASU 2018-11, elected to recognize the related cumulative-effect adjustment as an adjustment to the opening balance of retained earnings. Adoption of ASU 2016-02 resulted in the addition of a right-of-use asset and lease related to certain banking offices under noncancelable operating lease agreements. The resulting increase did not to have a material impact on the Company’s consolidated financial statements or regulatory capital ratios. For more information see Note 8 ‑ Leases in this report. In March 2017, FASB issued ASU No. 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The ASU shortens the amortization period for certain callable debt securities held at a premium. The Company adopted this ASU during the quarter ended March 31, 2019 with no material impact on the Company's consolidated financial statements. Recent Accounting Pronouncements ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) as amended by ASU 2018-19, ASU 2019-04 and ASU 2019-05, was originally issued in June 2016. This ASU replaces the existing incurred loss impairment methodology that recognizes credit losses when a probable loss has been incurred with new methodology where loss estimates are based upon lifetime expected credit losses. The amendments in this ASU require a financial asset that is measured at amortized cost to be presented at the net amount expected to be collected. The income statement would then reflect the measurement of credit losses for newly recognized financial assets as well as changes to the expected credit losses that have taken place during the reporting period. The measurement of expected credit losses will be based on historical information, current conditions, and reasonable and supportable forecasts that impact the collectability of the reported amount. Available‑for‑sale securities will bifurcate the fair value mark and establish an allowance for credit losses through the income statement for the credit portion of that mark. The interest portion will continue to be recognized through accumulated other comprehensive income or loss. The change in allowance recognized as a result of adoption will occur through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the ASU is adopted. The amendments in this ASU are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted for fiscal years beginning after December 15, 2018, however the FASB proposed in July 2019 extending the adoption date for certain registrants, including the Company, to fiscal years beginning after December15, 2022. The Company is evaluating our current expected loss methodology of our loan and investment portfolios to identify the necessary modifications in accordance with this standard and expects a change in the processes and procedures to calculate the ALLL, including changes in assumptions and estimates to consider expected credit losses over the life of the loan versus the current accounting practice that utilizes the incurred loss model. A valuation adjustment to our ALLL or investment portfolio that is identified in this process will be reflected as a one-time adjustment in equity rather than earnings. ASU 2019-05 issued in April 2019 further provides that entities that have certain financial instruments measured at amortized cost that have credit losses, to irrevocably elect the fair value option in Subtopic 825-10, upon adoption of Topic 326. The fair value option applies to available-for-sale debt securities. This ASU is effective upon adoption of ASU 2016-13, and should be applied on a modified-retrospective basis as a cumulative-effect adjustment to the opening balance of retained earnings in the statement of financial condition as of the adoption date. We are in the process of compiling historical and industry data that will be used to calculate expected credit losses on our loan portfolio to ensure we are fully compliant with the ASU at the adoption date and are evaluating the potential impact adoption of this ASU will have on our consolidated financial statements. The Company intends to adopt ASU 2016-13 in the first quarter of 2022, subject to the passing of the FASB proposed extension, and as a result, we expect our allowance for loan losses to increase. Until our evaluation is complete, however, the magnitude of the increase will not be known.
