New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Authoritative Accounting Guidance	Note 1a. Authoritative Accounting Guidance *Adoption of New Accounting Standards* Effective January 1, 2019, the Company implemented ASU No. 2016-02, “Leases (Topic 842)” (modified by ASU 2018-01 – Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842) and ASU 2018-20 – Leases (Topic 842) Narrow – Scope Improvements for Lessors). ASU 2016-02 requires the recognition of a right of use asset and related lease liability by lessees for leases classified as operating leases under current GAAP. Topic 842, which replaces the current guidance under Topic 840, retains a distinction between finance leases and operating leases. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee also will not significantly change from current GAAP. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize right of use assets and lease liabilities. Effective with the adoption, the Company recognized a “right-of-use-asset” and a “lease liability” for its operating leases and has elected to apply practical expedients pertaining to the ASU. The Company applied a modified retrospective transition approach for the applicable leases. ASU 2016-02 provides for a modified retrospective transition approach requiring lessees to recognize and measure leases on the balance sheet at the beginning of either the earliest period presented or as of the beginning of the period of adoption. The Company elected to apply ASU 2016-02 as of the beginning of the period of adoption (January 1, 2019) and will not restate comparative periods. The Company has also elected to use the practical expedient to make an accounting policy election for property leases to include both lease and non-lease components as a single component and account for it as a lease. The adoption of ASU 2016-02 resulted in the recognition of $15.3 million of “right-of-use assets” and $16.7 million of lease liabilities as of the date of the adoption. This adoption did not materially impact the Company’s Consolidated Statement of Income for the first quarter ended March 31, 2019 and it is not expected to have a material impact on the Consolidated Statement of Income in future periods. See Note 9 – Premises and Equipment for additional disclosures related to leases. *Newly Issued, But Not Yet Effective Accounting Standards* SU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Assets Measured at Amortized Cost.” (modified by ASU 2018-19 – Codification Improvements to Topic 326, Financial Instruments –Credit Losses). 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 public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company has formed a CECL committee which has assessed our data and system needs. The Company has engaged third-party vendors to assist in analyzing our data and developing a CECL model. The Company, in conjunction with these vendors, has researched and analyzed modeling standards, loan segmentation, as well as potential external inputs to supplement our historical loss history. We expect to recognize a one-time cumulative effect adjustment to the allowance for loan losses as of the beginning of the first reporting period in which the ASU is effective, but cannot yet determine the magnitude of any such one-time adjustment or the overall impact of the ASU on our consolidated financial statements. ASU No. 2017-08, “Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities.” ASU No. 2017-08 shortens the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. ASU 2017-08 will be effective for public business entities for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. We are currently evaluating this ASU to determine the impact on our consolidated financial statements. ASU 2018-15, “Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.” These amendments align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by these amendments. ASU 2018-15 is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2019. We believe the adoption of this standard will not have a significant impact on our consolidated financial statements. ASU 2018-14, “Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans.” These amendments modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. ASU 2018-14 is effective for fiscal years ending after December 15, 2020. We believe the adoption of this standard will not have a significant impact on our consolidated financial statements. ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement.” The amendments in this update modify disclosure requirements on fair value measurements by removing, modifying and adding certain disclosure requirements. The amendments primarily pertain to Level 3 fair value measurements and depending on the amendment are applied either prospectively or retrospectively. ASU 2018-13 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. We believe the adoption of this standard will not have a significant impact on our consolidated financial statements. ASU No. 2017-04, “Intangibles – Goodwill and Other (Topic 350).” ASU 2017-04 aims to simplify the subsequent measurement of goodwill. Under these amendments, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. The Board also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment. An entity is required to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets and still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2019. Although management continues to evaluate the potential impact of ASU 2017-04 on our consolidated financial statements, at this time, we believe the adoption of this standard will not have a significant impact on our consolidated financial statements.
