The interim consolidated financial statements and the accompanying notes should be read in conjunction with the annual consolidated financial statements and the accompanying notes contained within the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020 (“2020 Form 10-K”), as filed with the SEC. In the opinion of management, the Company’s consolidated financial statements reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of the results of operations for the periods presented. The results for the three months ended March 31, 2021 are not necessarily indicative of results to be expected for the year ending December 31, 2021, any other interim periods, or any future year or period.
Use of Estimates	Use of Estimates In preparing the Consolidated Financial Statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheets and income and expenses for the periods reported. Actual results could differ from those estimates based on changing conditions, including economic conditions and future events. Material estimates that are particularly susceptible to change relate to the determination of the allowance for loan losses, valuation and fair value measurements, other-than-temporary impairment on investment securities, the liabilities for benefit obligations (particularly pensions), the provision for income taxes and impairment of goodwill and other intangibles.
Recent Accounting Pronouncements	Recent Accounting Pronouncements The Company qualifies as an emerging growth company under the Jumpstart Our Business Act of 2012 (“JOBS Act”) and has elected to defer the adoption of new or revised accounting standards until the nonpublic company effective dates. Relevant standards that were recently issued but not yet adopted as of March 31, 2021: In March 2020, the FASB issued ASU 2020-4, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). This update addresses optional expedients and exceptions for applying GAAP to certain contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The new guidance applies only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. For public and nonpublic entities, the guidance is effective as of March 12, 2020 through December 31, 2022 and does not apply to contract modifications made after December 31, 2022. The Company will adopt this standard on the nonpublic company effective date and is currently in the process of reviewing its contracts and existing processes in order to assess the risks and potential impact of the transition away from LIBOR. In June 2016, the FASB issued ASU 2016-13, Financial Instruments–Credit Losses on Financial Instruments and relevant amendments (Topic 326) (“ASU 2016-13”). This update was created to replace the current GAAP method of calculating credit losses. Specifically, the standard replaces the existing incurred loss impairment guidance by requiring immediate recognition of expected credit losses. For financial assets carried at amortized cost that are held at the reporting date (including trade and other receivables, loans and commitments, held-to-maturity debt securities and other financial assets), credit losses are measured based on historical experience, current conditions and reasonable supportable forecasts. The standard also amends existing impairment guidance for available for sale securities, in which credit losses will be recorded as an allowance versus a write-down of the amortized cost basis of the security. It will also allow for a reversal of impairment loss when the credit of the issuer improves. The guidance requires a cumulative effect of the initial application to be recognized in retained earnings at the date of initial application. In November 2018, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments – Credit Losses (“ASU 2018-19”). The amendments in ASU 2018-19 were intended to clarify that receivables arising from operating leases are not within the scope of Subtopic 326-20. Instead, impairment of receivables arising from operating leases should be accounted for in accordance with Topic 842, Leases. In November 2019, the FASB issued ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments – Credit Losses. This update requires entities to include expected recoveries of the amortized cost basis previously written off or expected to be written off in the valuation account for purchased financial assets with credit deterioration. In addition, the amendments in this update clarify and improve various aspects of the guidance for ASU 2016-13. For public entities that meet the definition of an SEC filer (excluding smaller reporting entities) the guidance is effective for annual reporting periods beginning after December 15, 2019. Early adoption is permitted for all entities as of the fiscal years beginning after December 15, 2018. For all other entities, the guidance is effective for annual reporting periods beginning after December 15, 2022, including interim periods within those fiscal years. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted in response to the COVID-19 pandemic in the United States. to provide economic relief measures including the option to defer adoption of ASU 2016-13 to the earlier of the ending of the national emergency declaration related to the COVID-19 crisis or December 31, 2020. On December 27, 2020, the Consolidated Appropriations Act (the “Appropriations Act”) was enacted to fund the federal government through their fiscal year, extend certain expiring tax provisions and provide additional emergency relief to individuals and businesses related to the COVID-19 pandemic in the United States. Included within the provisions of the Appropriations Act is an extension of the adoption date for ASU 2016-13 from December 31, 2020 to the earlier of January 1, 2022 or 60 days after the date on which the COVID-19 national emergency terminates. The Company anticipates deferring adoption of this standard to January 1, 2022. To address the impact of ASU 2016-13, the Company has formed a committee, including the Chief Credit Officer, the Chief Financial Officer, and Chief Information Officer, to assist in identifying, implementing, and evaluating the impact of the required changes to loan loss estimation models and processes. The Company has evaluated portfolio segmentation, methodologies and economic forecasting inputs to the process and continues to design the control environment under the new standard. A third party has been engaged to assist the Company in project management, documentation, model governance and related internal controls implementation. The Company is currently assessing the impact of the new standard on its consolidated financial statements. In August 2018, the FASB issued ASU 2018-14, Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20) Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans (“ASU 2018-14”). This update modifies the disclosure requirements for employers that sponsor defined benefit pension and/or other postretirement benefit plans. The guidance eliminates requirements for certain disclosures that are no longer considered cost beneficial and requires new ones that the FASB considers pertinent. For public companies, ASU 2018-14 is effective for fiscal years ending after December 15, 2020. For nonpublic companies, ASU 2018-14 is effective for fiscal years ending after December 15, 2021. Early adoption is permitted. The Company will adopt this standard on the nonpublic company effective date. The Company expects the adoption of this standard will not have a material impact on its consolidated financial statements. Relevant standards that were adopted during the period ended March 31, 2021: In August 2018, the FASB issued 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 (“ASU 2018-15”). This update addresses accounting for fees paid by a customer for implementation, set-up and other upfront costs incurred in a cloud computing arrangement that is hosted by the vendor (i.e., a service contract). The new guidance aligns treatment for capitalization of implementation costs with guidance on internal-use software. For public entities, the guidance is effective for annual reporting periods beginning after December 15, 2019. For nonpublic entities, the guidance is effective for annual reporting periods beginning after December 15, 2020, and for all interim periods beginning after December 15, 2021. The adoption of this standard on January 1, 2021 did not have a material impact on the Company’s consolidated financial statements. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848) (“ASU 2021-01”) which expands the scope of guidance in ASC 848 so that companies can apply the optional expedients to derivative instruments affected by the clearing house changes. ASU 2021-01 also clarifies and updates several items in ASU 2020-04 as part of the Board’s monitoring of global reference rate reform activities. ASU 2021-01 permits entities to elect certain optional expedients and exceptions to modifications of interest rate indexes used for computing when accounting derivative contracts and certain hedging relationships impacted by changes in interest rates used for discounting, margining, or contract price alignment. ASU 2021-01 clarifies other aspects of the guidance in ASC 848 and provides new guidance on how to address the effects of the cash compensation adjustment that is provided as part of the above change on certain aspects of hedge accounting. The guidance was effective upon issuance and allows for retrospective or prospective application with certain conditions. The Company did not elect retrospective application. The adoption of this update did not have a material impact on the Company’s consolidated financial statements.
