New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted: Leases In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” This standard requires organizations to recognize right-to-use ("ROU") assets and lease liabilities on the balance sheet and disclose key information about leasing requirements for leases that were historically classified as operating leases under previous generally accepted accounting principles. Leases will be classified as financing or operating, with classification affecting the pattern and classification of expense recognition in the income statement. Topic 842 was subsequently amended by ASU No. 2018-01 "Land Easement Practical Expedient for Transition to Topic 842," ASU No. 2018-10, "Codification Improvements to Topic 842, Leases," ASU No. 2018-11 "Targeted Improvements," ASU No. 2018-20 "Narrow-Scope Improvements for Lessors," and ASU No. 2019-01 "Codification Improvements." The Company adopted the new standard on January 1, 2019 and has chosen to use that date as the effective date of initial application. Consequently, financial information will not be updated and the disclosures required under the new standard will not be provided for dates and periods before January 1, 2019. The new standard provides a number of optional practical expedients in transition. The Company has elected the "package of practical expedients," which permits it to not reassess under the new standard its prior conclusions about lease identification, lease classification and initial direct costs. As part of the adoption of this standard, the Company recognized lease liabilities, with corresponding ROU assets of approximately the same amount based on the present value of the remaining minimum rental payments under current leasing standards for existing operating leases. The adoption of this standard did not have a material impact on the Company's financial statements. Operating lease expense is recognized on a straight-line basis over the lease term. Others In March 2017, the FASB issued ASU No. 2017-08, "Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities." The amendments in this update shorten the amortization period for certain callable debt securities held at a premium and require the premium to be amortized to the earliest call date. This ASU became effective for the Company on January 1, 2019. The adoption of ASU No. 2017-08 did not have a material impact on the Company's financial statements. In August 2017, the FASB issued ASU No. 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities." This amendment expands and refines hedge accounting for both nonfinancial and financial risk components and aligns the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. This ASU became effective for the Company on January 1, 2019. The adoption of this ASU did not have a material impact on the Company's financial statements. In April 2019, the FASB issued ASU No. 2019-04, "Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments." This amendment clarifies the guidance in ASU No. 2017-12. This ASU will become effective for the Company on January 1, 2020. The adoption of ASU No. 2019-04 is not expected to have a material impact on the Company's financial statements. In October 2018, the FASB issued ASU No. 2018-16, "Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes." This amendment permits the use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to the UST, the LIBOR swap rate, the OIS rate based on the Federal Funds Effective Rate, and the SIFMA Municipal Swap Rate. This ASU became effective for the Company on January 1, 2019. The adoption of ASU No. 2017-12 did not have a material impact on the Company's financial statements. Pending Adoption: CECL In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." This standard replaces 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. The amendments in this update require 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 new current expected credit losses model ("CECL") will apply to the allowance for loan losses, available-for-sale and held-to-maturity debt securities, purchased financial assets with credit deterioration and certain off-balance sheet credit exposures. In November 2018, the FASB issued ASU No. 2018-19, "Codification Improvements to Topic 326, Financial Instruments—Credit Losses." This amendment clarifies the scope of the guidance in ASU No. 2016-13. In April 2019, the FASB issued ASU No. 2019-04, "Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments." This amendment clarifies the guidance in ASU No. 2016-13. These ASUs will become effective for the Company for interim and annual periods on January 1, 2020. Management is currently working through its implementation plan, including implementing a third-party vendor solution program. The adoption of these ASUs could result in a material increase to the allowance for loan losses. While we are currently unable to reasonably estimate the impact of adopting these ASUs, management expects that the impact of adoption will be significantly influenced by the loan portfolio's composition and quality, as well as the prevailing economic conditions and forecasts as of the adoption date. Others In January 2017, the FASB issued ASU No. 2017-04, "Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." This amendment simplifies the measurement of goodwill by eliminating Step 2 from the goodwill impairment test. This ASU will become effective for the Company on January 1, 2020. The adoption of ASU No. 2017-04 is not expected to have a material impact on the Company's financial statements. In August 2018, the FASB issued ASU No. 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement." This amendment removes, modifies, and clarifies the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement. This ASU will become effective for the Company on January 1, 2020. The adoption of ASU No. 2018-13 is not expected to have a material impact on the Company's financial statements. In August 2018, the FASB issued ASU No. 2018-14, "Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans." This amendment removes, modifies, and clarifies certain disclosure requirements for defined benefit plans and other post-employment benefit plans. This ASU will become effective for the Company on January 1, 2021. The adoption of ASU No. 2018-14 is not expected to have a material impact on the Company's financial statements. In October 2018, the FASB issued ASU No. 2018-17, "Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities." This amendment simplifies the analysis of fees paid to decision makers or service providers in determining variable interest entities. This ASU will become effective for the Company on January 1, 2020. The adoption of ASU No. 2018-17 is not expected to have a material impact on the Company's financial statements.
