Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited Consolidated Financial Statements were prepared in accordance with GAAP and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the Corporation’s Consolidated Financial Statements and footnotes thereto included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2019.
Principles of Consolidation	The unaudited Consolidated Financial Statements include the accounts of the Corporation and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. In accordance with the provisions of Accounting Standards Codification (“ASC”) Topic 810, the Corporation’s ownership interest in FBFS Statutory Trust II (“Trust II”) has not been consolidated into the financial statements.
Use of Estimates	Management of the Corporation is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements as well as reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from those estimates. Material estimates that could significantly change in the near-term include the value of securities and interest rate swaps, level of the allowance for loan and lease losses, lease residuals, property under operating leases, goodwill, level of the Small Business Administration (“SBA”) recourse reserve, and income taxes.
Reclassification	Certain amounts in prior periods may have been reclassified to conform to the current presentation.
Subsequent Events	Subsequent events have been evaluated through the date of the issuance of the unaudited Consolidated Financial Statements. No significant subsequent events have occurred through this date requiring adjustment to the financial statements or disclosures.
Recent Accounting Pronouncements	Adoption of New Accounting Standards In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-04, “Intangibles - Goodwill and Other (Topic 350).” The ASU amended existing guidance to simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. The amendments require an entity to perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, not to 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 amendments also eliminate the requirement for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. The Corporation adopted the accounting standard during the first quarter of 2020. The adoption of the standard did not have a material impact on the Corporation’s results of operations, financial position, and liquidity. In August 2018, the FASB issued ASU No. 2018-15, “Intangibles-Goodwill and Other Internal-Use Software (Subtopic 350-40).” The ASU aligns 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). Implementation costs incurred in the application development stage are capitalized depending on the nature of the costs, while costs incurred during the preliminary project and post implementation stages are expensed as the activities are performed. The amendment also requires entities to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement and in the same income statement line item as the fees associated with the hosting element. The Corporation adopted the accounting standard during the first quarter of 2020. The adoption of the standard did not have a material impact on the Corporation’s results of operations, financial position, and liquidity. Recent Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments- Credit Losses (Topic 326),” which is often referred to as CECL. The ASU replaces the incurred loss impairment methodology for recognizing credit losses with a methodology that reflects all expected credit losses. The ASU also requires consideration of a broader range of information to inform credit loss estimates, including such factors as past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The amendments affect loans, debt securities, trade receivables, net investments in leases, off-balance sheet credit exposures, and any other financial asset not excluded from the scope under which the Corporation has the contractual right to receive cash. Entities will apply the amendments in the ASU through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. In November 2019, the FASB issued ASU No. 2019-10, “Financial Instruments-Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842).” The ASU delays the effective date for the credit losses standard from January 2020 to January 2023 for certain entities, including certain Securities and Exchange Commission filers, public business entities, and private companies. As a smaller reporting company, the Corporation is eligible for the delay and will be deferring adoption. The Corporation has established a cross-functional committee and has implemented a third-party software solution to assist with the adoption of the standard. Management has gathered all necessary data and reviewed potential methods to calculate the expected credit losses. Management is currently calculating sample expected loss computations and developing the allowance methodology and assumptions that will be used under the new standard. Management will continue to progress on its implementation project plan and improve the Corporation’s approach throughout the deferral period. In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (Topic 848).” The ASU provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendment only applies to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The ASU is effective as of March 12, 2020 through December 31, 2022. The Corporation is in the process of evaluating the impact of this standard but does not expect this standard to have a material impact on its results of operations, financial position, and liquidity.
