Accounting Standards Update and Change in Accounting Principle [Text Block] | 3. Recent Accounting Pronouncements Accounting Standards Adopted in 2021 In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This update requires an entity to use a broader range of R&S forecasts, in addition to historical experience and current conditions, to develop an expected credit loss estimate, referred to as the CECL model, for financial assets and net investments that are not accounted for at fair value through net income. Credit losses relating to available-for-sale debt securities should be recorded through an allowance for credit losses to the amount by which fair value is below amortized cost. The FASB issued additional ASUs containing clarifying guidance, transition relief provisions and minor updates to the original ASU. These include ASU 2018-19 (issued November 2018), ASU 2019-04 (issued April 2019), ASU 2019-05 (issued May 2019), ASU 2019-10 (issued November 2019), ASU 2019-11 (issued November 2019), ASU 2020-02 (issued February 2020) and ASU 2020-03 (issued March 2020). ASU 2016-13 and subsequent ASUs are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. This amendment is required to be adopted using a modified retrospective approach with a cumulative-effect adjustment to beginning retained earnings, as of the beginning of the first reporting period in which the guidance is effective. Effective January 1, 2021, the Company adopted ASU 2016-13 and the related amendments to ASC Topic 326, Financial Instruments - Credit Losses, to replace the incurred loss accounting approach with a CECL approach for financial instruments measured at amortized cost and other commitments to extend credit. The new standard is generally intended to require earlier recognition of credit losses. While the standard changes the measurement of the allowance for credit losses, it does not change the credit risk of our lending portfolios or the ultimate losses in those portfolios. Under the CECL approach, the standard requires immediate recognition of estimated credit losses expected to occur over the estimated remaining life of the asset. The forward-looking concept of CECL requires loss estimates to consider historical experience, current conditions and reasonable and supportable forecasts. The standard modifies the other-than-temporary impairment model for available-for-sale debt securities to require entities to record an allowance when recognizing credit losses for available-for-sale securities, rather than reducing the amortized cost of the securities by direct write-offs. The Company adopted the new standard using the modified retrospective approach and recognized a cumulative effect adjustment to decrease retained earnings by $0.8 million, net of taxes, and increase the allowance for credit losses by $0.6 million and the reserve for unfunded loan commitments by $0.5 million without restating prior periods and applied the requirements of the new standard prospectively. There was no cumulative effect adjustment related to available-for-sale securities at adoption. The Company elected to account for accrued interest receivable separately from the amortized cost of loans and investment securities. Accrued interest receivable is included in "accrued interest receivables" on the Condensed Consolidated Balance Sheets. The Company elected the practical expedient to use the fair value of the collateral at the reporting date when determining the allowance for credit losses for a financial asset for which the repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty based on the entity’s assessment as of the reporting date (collateral dependent financial asset). Additionally, the Company implemented new business processes, new internal controls, and modified existing and/or implemented new internal models and tools to facilitate the ongoing application of the new standard. See Note 8. Loans for further details. The following table sets forth the cumulative effect of the changes to the Company's unaudited Condensed Consolidated Balance Sheets at January 1, 2021, for the adoption of ASC 326:
|  | Balance at December 31, 2020 |  |  | Adjustments Due to Adoption of ASC 326 |  |  | Balance at January 1, 2021 |
|  | (In thousands) |
Assets: |  |  |  |  |  |  |  |  |  |  |  |
Allowance for credit losses on loans |  | $ | 166,538 |  |  | $ | 594 |  |  | $ | 167,132 |
Deferred tax assets |  |  | 85,610 |  |  |  | 335 |  |  |  | 85,945 |
Liabilities: |  |  |  |  |  |  |  |  |  |  |  |

Retained earnings, net of tax |  |  | 2,418,144 |  |  |  | (798 | ) |  |  | 2,417,346 |
In July 2017, the FASB issued ASU 2017-11, “Earnings per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480) and Derivatives and Hedging (Topic 815).” There are two parts to this update. Part I of this update addresses the complexity of accounting for certain financial instruments with down round features. Down round features are features of certain equity-linked instruments that result in the strike price being reduced on the basis of the pricing of future equity offerings. Part II of this update addresses the difficulty in navigating Topic 480, Distinguishing Liabilities from Equity, because of the existence of extensive pending content in the FASB Accounting Standards Codification. This pending content is the result of the indefinite deferral of accounting requirements about mandatorily redeemable financial instruments of certain nonpublic entities and certain mandatorily redeemable noncontrolling interests. The amendments in this update are effective for fiscal years beginning after December 15, 2020. Early adoption is permitted for all entities, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The amendments in part I of this update should be applied in either of the following ways: (i) Retrospectively to outstanding financial instruments with a down round feature by means of a cumulative-effect adjustment to the statement of financial position as of the beginning of the first fiscal year and interim periods in which the pending content that links to this paragraph is effective; or (ii) Retrospectively to outstanding financial instruments with a down round feature for each prior reporting period presented in accordance with the guidance on accounting changes in paragraphs 250-10-45-5 through 45-10. The amendments to Part II of this update do not require any transition guidance because those amendments do not have an accounting effect. Adoption of ASU 2017-11 did not have a material impact on the Company’s Condensed Consolidated Financial Statements. In December 2019, the FASB issued ASU No. 2019-12, “Income Taxes (Topic 740); Simplifying the Accounting for Income Taxes.” This ASU removes specific exceptions to the general principles in Topic 740 in Generally Accepted Accounting Principles. It eliminates the need for an organization to analyze whether the following apply in a given period: exception to the incremental approach for intra-period tax allocation; exception to accounting for basis differences when there are ownership changes in foreign investments; and exception in interim period income tax accounting for year-to-date losses that exceed anticipated losses. The ASU also improves financial statement preparers’ application of income tax-related guidance and simplifies GAAP for: Franchise taxes that are partially based on income; transactions with a government that result in a step up in the tax basis of goodwill; separate financial statements of legal entities that are not subject to tax; and enacted changes in tax laws in interim periods. This ASU is effective for public business entities, for fiscal years beginning after December 15, 2020 with early adoption permitted for public business entities for periods for which financial statements have not yet been issued. Adoption of ASU 2019-12 did not have a material impact on the Company’s Condensed Consolidated Financial Statements. In January 2020, the FASB issued ASU No. 2020-01, “'Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint-Ventures (Topic 323), and Derivatives and Hedging (Topic 815). Clarifying the Interactions between Topic 321, Topic 323, and Topic 815.” This ASU is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early application is permitted, including early adoption in an interim period for public business entities for periods for which financial statements have not yet been issued. An entity should apply ASU No. 2020-01 prospectively at the beginning of the interim period that includes the adoption date. This ASU among other things clarifies that a company should consider observable transactions that require a company to either apply or discontinue the equity method of accounting under Topic 323, Investments—Equity Method and Joint Ventures, for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. The new ASU clarifies that, when determining the accounting for certain forward contracts and purchased options a company should not consider, whether upon settlement or exercise, if the underlying securities would be accounted for under the equity method or fair value option. Adoption of ASU 2020-01 did not have a material impact on the Company’s Condensed Consolidated Financial Statements. Other Accounting Standards Pending Adoption In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” ASU No. 2020-04 is effective for all entities as of March 12, 2020 through December 31, 2022. This ASU provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. The ASU is intended to help stakeholders during the global market-wide reference rate transition period. Therefore, it will be in effect for a limited time through December 31, 2022. The Company is evaluating the impact of adopting ASU 2020-02 on the Company’s Consolidated Financial Statements. In October 2020, the FASB issued ASU 2020-08, “Codification Improvements to Subtopic 310-20, Receivables, Nonrefundable Fees and Other Costs.” ASU 2020-08 clarifies the accounting for the amortization of purchase premiums for callable debt securities with multiple call dates. ASU 2020-8 became effective for the Company on January 1, 2021, and is not expected to have a significant impact on the Company's Consolidated Financial Statements. In January 2021, the FASB issued ASU 2021-01, “Reference Rate Reform (Topic 848): Scope.” ASU 2021-01 clarifies that certain optional expedients and exceptions in ASC 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. ASU 2021-01 also amends the expedients and exceptions in ASC 848 to capture the incremental consequences of the scope clarification and to tailor the existing guidance to derivative instruments affected by the discounting transition. ASU 2021-01 was effective upon issuance and generally can be applied through December 31, 2022. The Company is evaluating the impact of adopting ASU 2021-01 on the Company’s Consolidated Financial Statements.
