Accounting Standards Update and Change in Accounting Principle [Abstract] |
Recent Accounting Pronouncements | Recent Accounting PronouncementsNonrefundable Fees and Other Costs: In October 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2020-08 “Codification Improvements to Subtopic 310-20, Receivables–Nonrefundable Fees and Other Costs.” This ASU clarifies that an entity should reevaluate whether a callable debt security is within the scope of ASC paragraph 310-20-35-33 for each reporting period. The guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early application is not permitted. All entities should apply ASU 2020-08 on a prospective basis as of the beginning of the period of adoption for existing or newly purchased callable debt securities. The Company adopted ASU 2020-08 as of January 1, 2021 and it did not have a material impact on its accounting and disclosures. Reference Rate Reform: 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.” These amendments provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. The ASU 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. It is intended to help stakeholders during the global market-wide reference rate transition period. In January 2021, the FASB issued ASU 2021-01 which clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The guidance is effective for all entities as of March 12, 2020 through December 31, 2022. The Company is implementing a transition plan to identify and modify its loans and other financial instruments with attributes that are either directly or indirectly influenced by LIBOR. The Company is continuing to assess ASU 2020-04 and its impact on the Company’s transition away from LIBOR for its loan and other financial instruments. Partnership Investments and Derivatives: 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.” These amendments, among other things, clarify 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 amendments also clarify 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. The guidance 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. An entity should apply ASU 2020-01 prospectively at the beginning of the interim period that includes the adoption date. The Company adopted ASU 2020-01 on January 1, 2021 and it did not have a material impact on its accounting and disclosures. Income Taxes: In December 2019, the FASB issued ASU 2019-12 “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” These amendments remove specific exceptions to the general principles in Topic 740 in GAAP. It eliminates the need for an organization to analyze whether the following apply in a given period: exception to the incremental approach for intraperiod tax allocation; exceptions to accounting for basis differences where there are ownership changes in foreign investments; and exception in interim period income tax accounting for year-to-date losses that exceed anticipated losses. It 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 enacts changes in tax laws in interim periods. The guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted. The Company adopted ASU 2019-12 on January 1, 2021 and it did not have a material impact on its accounting and disclosures. Measurement of Credit Losses on Financial Instruments: In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments-Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments (CECL).” The provisions of ASU 2016-13 were issued to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments that are not accounted for at fair value through net income, including loans held for investment, held-to-maturity debt securities, trade and other receivables, net investment in leases and other commitments to extend credit held by a reporting entity at each reporting date. ASU 2016-13 requires that financial assets measured at amortized cost be presented at the net amount expected to be collected, through an allowance for credit losses that is deducted from the amortized cost basis. The amendments in ASU 2016-13 eliminate the probable incurred loss recognition in current GAAP and reflect an entity’s current estimate of all expected credit losses. The measurement of expected credit losses is based upon historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the financial assets. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses rather than as a direct write-down to the security. 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. As previously disclosed, the Company formed a cross-functional team to work through its implementation plan. The Company’s cross-functional team completed the assessment and documentation of processes, internal controls, data and model validation testing, parallel testing, qualitative factors and forecast periods as well as model development. The Company implemented a third-party software solution to assist in the application of the new standard including portfolio segmentation according to shared risk characteristics and modeling methodologies. The Company had finalized the formal review and approval process and the results of its CECL estimate as of year-end 2019 but elected to delay its adoption of ASU 2016-13, as approved by the Coronavirus Aid, Relief, and Economic Security (CARES) Act, until December 31, 2020. Upon adoption of ASU 2016-13, the Company recognized a one-time cumulative effect adjustment decreasing retained earnings as of January 1, 2020 by $2.55 million, net of deferred taxes of $0.81 million. Upon adopting ASU 2016-13, the Company did not record an allowance as of January 1, 2020 with respect to its available-for-sale debt securities as the majority of these securities are government agency-backed securities for which the risk of loss is minimal. The adoption of ASU 2016-13 did not have a significant impact on the Company’s regulatory capital ratios. The accounting policies stated in Note 1 relating to the allowance for credit losses on available-for-sale investment securities, loans and leases and unfunded loan commitments reflect the current accounting policies required by ASU 2016-13. Disclosures relating to prior year accounting policies can be found in the 2019 Annual Report on Form 10-K. The main drivers of the adjustment to retained earnings are summarized in the following table.
