Accounting Policies [Abstract]
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with instructions to Form 10-Q. Accordingly, they do not include all the information and footnotes required by U.S. GAAP for annual year-end financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included and are of a normal, recurring nature. The consolidated balance sheet as of December 31, 2019 has been derived from audited financial statements included in the Company’s 2019 filing on Form 10-K. Operating results for the three and nine months ended September 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020.
Use of Estimates	The preparation of the financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Estimates, such as the allowance for loan losses, are based upon known facts and circumstances. Estimates are revised by management in the period such facts and circumstances change. Actual results could differ from those estimates.
Consolidation	All significant inter-company accounts and transactions have been eliminated in consolidation.
Equity Method Investments	Unconsolidated investments where the Company has the ability to exercise significant influence over the operating and financial policies of the respective investee are accounted for using the equity method of accounting; those that are not consolidated or accounted for using the equity method of accounting are accounted for under cost or fair value accounting. For these investments accounted for under the equity method, the Company records its investment in non-consolidated affiliates and the portion of income or loss in equity in earnings of non-consolidated affiliates. The Company periodically evaluates these investments for impairment. As of September 30, 2020, the Company holds one equity method investment.
Business Combinations	Business Combinations U.S. GAAP requires that the acquisition method of accounting, formerly referred to as the purchase method, be used for all business combinations that an acquirer be identified for each business combination. Under U.S. GAAP, the acquirer is the entity that obtains control of one or more businesses in the business combination, and the acquisition date is the date the acquirer achieves control. U.S. GAAP requires that the acquirer recognize the fair value of assets acquired, liabilities assumed, and any non-controlling interest in the acquired entity at the acquisition date.
Purchased Credit Impaired Loans	Purchased Credit Impaired Loans Through the Federal Deposit Insurance Corporation ("FDIC")-assisted acquisition of The First State Bank (“First State”), the Company purchased individual loans and groups of loans, some of which have shown evidence of credit deterioration since origination. These purchased credit impaired (“PCI”) loans are recorded at the amount paid, such that there is no carryover of the seller's allowance for loan losses. After acquisition, losses are recognized by an increase in the allowance for loan losses. Such PCI loans are accounted for individually or aggregated into pools of loans based on common risk characteristics such as, credit score, loan type, and date of origination. The Company estimates the amount and timing of expected cash flows for each loan or pool, and the expected cash flows in excess of amount paid is recorded as interest income over the remaining life of the loan or pool (accretable yield). The excess of the loan's or pool's contractual principal and interest over expected cash flows is not recorded (non-accretable difference). Over the life of the loan or pool, expected cash flows continue to be estimated. If the present value of expected cash flows is less than the carrying amount, a loss is recorded as a provision for loan losses. If the present value of expected cash flows is greater than the carrying amount, it is recognized as part of future interest income. For more information on the PCI loans, see Note 4, “Loans and Allowance for Loan Losses” of the Notes to the Consolidated Financial Statements, included in Item 1, Financial Statements, of this Quarterly Report on Form 10-Q.
Recent Accounting Pronouncements	In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-14, Compensation – Retirement Benefits – Defined Benefit Plans – General (Subtopic 715-20): Disclosure Framework – Changes to the Disclosure Requirement for Defined Benefit Plans, which modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The updates in this ASU are part of the disclosure framework project ASU 2018-14 and modify the disclosure requirements under Accounting Standards Codification ("ASC") 715-20 for employers that sponsor defined benefit pension or other postretirement plans. Those modifications include the removal, addition, and of disclosure requirements as well as clarifying specific disclosure requirements. The ASU removed the following disclosures: 1) the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year; 2) the amount and timing of plan assets expected to be returned to the employer; 3) the disclosures related to the June 2001 amendments to the Japanese Welfare Pension Insurance Law; 4) related party disclosures about the amount of future annual benefits covered by insurance and annuity contracts and significant transactions between the employer or related parties and the plan; 5) for nonpublic entities, the reconciliation of the opening balances to the closing balances of plan assets measured on a recurring basis in Level 3 of the fair value hierarchy; however, nonpublic entities will be required to disclose separately the amounts of transfers into and out of Level 3 of the fair value hierarchy and purchases of Level 3 plan assets and 6) for public entities, the effects of a one-percentage-point change in assumed health care cost trend rates on the (i) aggregate of the service and interest cost components of net periodic benefit costs and (ii) benefit obligation for postretirement health care benefits. The ASU added the following disclosures: 1) the weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates and 2) an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. The ASU then clarified the following disclosures: 1) the projected benefit obligation (“PBO”) and fair value of plan assets for plans with PBOs more than plan assets; and 2) the accumulated benefit obligation (“ABO”) and fair value of plan assets for plans with ABOs more than plan assets. ASU 2018-14 will be effective for public business entities for fiscal years ending after December 15, 2020. As ASU 2018-14 only revises disclosure requirements, it will not have a material impact on the Company's consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. The updates in this ASU are part of the disclosure framework project and modify the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement. The modifications include additions, modification, and removal of disclosure requirements. The ASU removed the following disclosure requirements: 1) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, 2) the policy for timing of transfers between levels, 3) the valuation process for Level 3 fair value measurements, and 4) for nonpublic entities, the changes in unrealized gains and losses for the period included in earnings for recurring Level 3 fair value measurements held at the end of the reporting period. The ASU added the following disclosure requirements: 1) the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period; and 2) the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements. The ASU also modified the following disclosure requirements: 1) in lieu of a rollforward for Level 3 fair value measurements, a nonpublic entity is required to disclose transfers into and out of Level 3 of the fair value hierarchy and purchases and issues of Level 3 assets and liabilities; 2) for investments in certain entities that calculate net asset value, an entity is required to disclose the timing of liquidation of an investee's assets and the date when restrictions from redemption might lapse only if the investee has communicated the timing to the entity or announced the timing publicly; and 3) clarification that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. ASU 2018-13 is effective for public business entities for fiscal years and interim periods within those years beginning after December 15, 2019. The Company adopted this standard and there was no material impact. In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and subsequent amendments to the initial guidance in November 2018, ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments – Credit Losses, in April 2019, ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments – Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, in May 2019, ASU 2019-05, Financial Instruments – Credit Losses, Topic 326, and in November 2019, ASU 2019-10, Financial Instruments – Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates, and ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments – Credit Losses, all of which clarifies codification and corrects unintended application of the guidance. The new guidance replaces the incurred loss impairment methodology in current U.S. GAAP with an expected credit loss methodology and requires consideration of a broader range of information to determine credit loss estimates. Financial assets measured at amortized cost will be presented at the net amount expected to be collected by using an allowance for credit losses. PCI loans will receive an allowance account at the acquisition date that represents a component of the purchase price allocation. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses, with such allowance limited to the amount by which fair value is below amortized cost. The guidance was initially effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. On November 15, 2019, the FASB issued ASU 2019-10, Financial Investments – Credit Issues (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates, which finalizes a delay in the effective date of the standard for smaller reporting companies until January 2023. The Company expects 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 new standard is effective, but cannot yet determine the magnitude of any such one-time adjustment or the overall impact of the new guidance on the consolidated financial statements. In that regard, we have formed a cross-functional implementation team. The team is working to develop an implementation plan which will include assessment and documentation of processes, internal controls and data sources; model development and documentation; and system configuration, among other things. We are also in the process of implementing a third-party vendor solution to assist us in the application of this standard. The adoption of the this standard could result in an increase in the allowance for loan losses as a result of changing from an “incurred loss” model, which encompasses allowances for current known and inherent losses within the portfolio, to an “expected loss” model, which encompasses allowances for losses expected to be incurred over the life of the portfolio. While we are currently unable to reasonably estimate the impact of adopting ASU 2016-13 , we expect that the impact of adoption will be significantly influenced by the composition, characteristics and quality of our loan portfolio as well as the prevailing economic conditions and forecasts as of the adoption date.
