Accounting Changes and Error Corrections [Abstract]
Authoritative Accounting Guidance	Note 1b –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 206-02 requires the recognition of a right of use asset and related lease liability by lessees for leases classified as operating leases under current GAAP. See Note 6 for further information regarding leases. Effective January 1, 2018, the Company implemented ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” The guidance affects the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements of financial instruments. The guidance also resulted in separate classification of equity securities previously included in available-for-sale securities on the consolidated statements of condition with changes in the fair value of the equity securities now being captured in the Consolidated Statement of Income. As a result, the Company recorded a cumulative-effect adjustment to the Consolidated Statement of Condition. See Note 17 - Comprehensive Income for further information. See Note 1 for the Company’s accounting policy on Equity Securities. Adoption of the standard also resulted in the use of an exit price rather than an entrance price to determine the fair value of loans not measured at fair value on a non-recurring basis in the Consolidated Statements of Condition. See Note 22 for further information regarding the valuation of these loans. Effective January 1, 2018, the Company implemented ASU 2018-02, “Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” Under ASU 2018-02, the FASB amended existing guidance to allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from The Tax Cuts and Jobs Act of 2017. Please see Note 17 for further information. Effective January 1, 2018, the Company implemented ASU 2017-07, “Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” Under ASU 2017-07, the FASB requires employers to report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. See Note 18 for further information. - 61 - Table of Contents CONNECTONE BANCORP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 1b. Authoritative Accounting Guidance – (continued) Effective January 1, 2018, the Company adopted ASU 2014-09 Revenue from Contracts with Customers and all subsequent amendments to the ASU (collectively, “ASC 606”), which (i) creates a single framework for recognizing revenue from contracts with customers that fall within its scope and (ii) revises when it is appropriate to recognize a gain (loss) from the transfer of nonfinancial assets, such as OREO. Please see Note 25 for further information. Newly Issued, But Not Yet Effective Accounting Standards 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. The Company will adopt Topic 326, as required, on January 1, 2020. The Company’s CECL implementation efforts are continuing to focus on completion of model validation, developing new disclosures, establishing formal policies and procedures and other governance and control documentation. Based on the Company’s portfolio balances, including the level of acquired loans and nonaccretable credit marks on PCI loans, and forecasted economic conditions as of January 1, 2020, management believes the adoption of the CECL standard will result in a material increase to its total current reserves. However, the ultimate amount of the increase will be contingent upon continued validation of our model, testing and refinement of the model methodologies and judgments utilized to determine the estimate. Based on implementation progress to date, the Company believes the capital adequacy requirements to which it and the Bank are subject to, and its business strategies and practices, will not be materially impacted following the adoption on January 1, 2020. 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 believe the adoption of this standard will not have a significant 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. - 62 - Table of Contents CONNECTONE BANCORP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 1b. Authoritative Accounting Guidance – (continued) 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.
