Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Nature of Operations Live Oak Bancshares, Inc. (collectively with its subsidiaries including Live Oak Banking Company, the “Company”) is a bank holding company headquartered in Wilmington, North Carolina incorporated under the laws of the State of North Carolina in December 2008. The Company conducts business operations primarily through its commercial bank subsidiary, Live Oak Banking Company (the “Bank”). The Bank was organized and incorporated under the laws of the State of North Carolina on February 25, 2008 and commenced operations on May 12, 2008. The Bank specializes in lending and deposit related services to small businesses nationwide. The Bank identifies and extends lending to credit-worthy borrowers both within specific industries, also called verticals, through expertise within those industries, and more broadly to select borrowers outside of those industries. A significant portion of the loans originated by the Bank are guaranteed by the Small Business Administration (“SBA”) under the 7(a) Loan Program and the U.S. Department of Agriculture’s ( “ USDA”) Rural Energy for America Program ("REAP"), Water and Environmental Program (“WEP”) and Business & Industry ( “ B&I”) loan programs. The Company’s wholly owned subsidiaries include the Bank, Government Loan Solutions, Inc. (“GLS”), Live Oak Grove, LLC (“Grove”), Live Oak Ventures, Inc. (“Live Oak Ventures”), and Canapi Advisors, LLC (“Canapi Advisors”). The Bank’s wholly owned subsidiaries are Live Oak Number One, Inc., Live Oak Clean Energy Financing LLC (“LOCEF”), Live Oak Private Wealth, LLC (“Live Oak Private Wealth”) and Tiburon Land Holdings, LLC “TLH”). Live Oak Number One, Inc. holds properties foreclosed on by the Bank. LOCEF provides financing to entities for renewable energy applications. Live Oak Private Wealth provides high-net-worth individuals and families with strategic wealth and investment management services. During the first quarter of 2022, Jolley Asset Management, LLC (“JAM”) was merged into Live Oak Private Wealth. JAM was previously a wholly owned subsidiary of Live Oak Private Wealth. TLH was formed in the third quarter of 2022 to hold land adjacent to the Bank's headquarters consisting of wetlands and other protected property for the use and enjoyment of the Bank's employees and customers. GLS is a management and technology consulting firm that advises and offers solutions and services to participants in the government guaranteed lending sector. GLS primarily provides services in connection with the settlement, accounting, and securitization processes for government guaranteed loans, including loans originated under the SBA 7(a) loan programs and USDA guaranteed loans. The Grove provides Company employees and business visitors an on-site restaurant location. Live Oak Ventures’ purpose is investing in businesses that align with the Company's strategic initiative to be a leader in financial technology. Canapi Advisors provides investment advisory services to a series of funds focused on providing venture capital to new and emerging financial technology companies. The Company generates revenue primarily from net interest income and secondarily through the origination and sale of government guaranteed loans. Income from the retention of loans is comprised of interest income. Income from the sale of loans is comprised of net gains on sales of loans along with loan servicing revenue and revaluation of related servicing assets. Offsetting these revenues are the cost of funding sources, provision for loan and lease credit losses, any costs related to foreclosed assets and other operating costs such as salaries and employee benefits, travel, professional services, advertising and marketing and tax expense. The Company also generates gains and losses arising from its financial technology investments in its fintech segment. General In the opinion of management, all adjustments necessary for a fair presentation of the financial position and results of operations for the periods presented have been included, and all intercompany transactions have been eliminated in consolidation. Results of operations for the three and nine months ended September 30, 2022 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2022. The Unaudited Condensed Consolidated Balance Sheet as of December 31, 2021 has been derived from the audited consolidated financial statements contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, filed with the Securities Exchange Commission on February 24, 2022 (SEC File No. 001-37497) (the “ 2021 Form 10-K ” ). A summary description of the significant accounting policies followed by the Company is set forth in Note 1 of the Notes to Consolidated Financial Statements in the Company’s 2021 Form 10-K. These Unaudited Interim Condensed Consolidated Financial Statements should be read in conjunction with the audited consolidated financial statements and footnotes in the Company's 2021 Form 10-K. The preparation of financial statements in conformity with United States generally accepted accounting principles ( “ GAAP ” ) requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and the reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from those estimates. Amounts in all tables in the Notes to Unaudited Condensed Consolidated Financial Statements have been presented in thousands, except percentage, time period, share and per share data or where otherwise indicated. Business Segments Operating segments are components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. Management has determined that the Company has two reportable operating segments: Banking and Fintech, as discussed more fully in Note 11. Segments. In determining the appropriateness of a segment definition, the Company considers the criteria of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 280, Segment Reporting . Reclassifications Certain reclassifications have been made to the prior period’s Unaudited Condensed Consolidated Financial Statements to place them on a comparable basis with the current year. Net income and shareholders’ equity previously reported were not affected by these reclassifications.

Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting PronouncementsIn March 2020, the FASB issued Accounting Standards Update (“ASU”) No. 2020-04 “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU 2020-04”). ASU 2020-04 provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments are effective for and can be adopted by the Company as of March 12, 2020, through December 31, 2022. The Company does not expect this standard will have a material impact on its consolidated financial statements. To address the discontinuance of LIBOR, the Company has stopped originating variable LIBOR-based loans effective December 31, 2021 and has started to negotiate loans using the preferred replacement index, the Secured Overnight Financing Rate (“SOFR”) or a relevant duration U.S. Treasury rate. For currently outstanding LIBOR-based loans, the timing and manner in which each customer’s contract transitions from LIBOR to another rate will vary on a case-by-case basis. The Company expects to complete all transitions by the second quarter of 2023 or at the next repricing date if later in 2023. In March 2022, the FASB issued ASU No. 2022-02 “Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings (“TDRs”) and Vintage Disclosures” (“ASU 2022-02”). ASU 2022-02 eliminates the accounting guidance for TDRs by creditors in ASC 310-40, Receivables – Troubled Debt Restructurings by Creditors , while enhancing disclosure requirements for certain loan refinancings and restructurings when a borrower is experiencing financial difficulty. Additionally, for public business entities, ASU 2022-02 requires that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of ASC 326-20, Financial Instruments – Credit Losses – Measured at Amortized Cost . The amendments in this standard will be effective for the Company on January 1, 2023. The Company does not believe this standard will have a material impact on its consolidated financial statements. In June 2022, the FASB issued ASU No. 2022-03 “Fair Value Measurement (Topic 820) Fair Value Measurement of Equity Securities Subject to Contractual Restrictions” (“ASU 2022-03”). ASU 2022-03 indicates a contractual sale restriction on equity securities should not be considered in measuring fair value, however, disclosure should be made about such restrictions. The amendments in this standard will be effective for the Company on January 1, 2024. The Company does not believe this standard will have a material impact on its consolidated financial statements.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic and diluted earnings per share are computed based on the weighted-average number of shares outstanding during each period. Diluted earnings per share reflects the potential dilution that could occur upon the exercise of stock options or upon the vesting of restricted stock grants, any of which would result in the issuance of common stock that would then share in the net income of the Company.

During the three months ended September 30, 2021, two mortgage-backed securities totaling $6.2 million were settled. During the nine months ended September 30, 2022, twenty mortgage-backed securities totaling $36.5 million were settled. During the nine months ended September 30, 2021, one US government agency matured at $5.0 million and eight mortgage-backed securities totaling $23.1 million were settled. Accrued interest receivable on available-for-sale securities totaled $2.9 million and $1.9 million at September 30, 2022 and December 31, 2021, respectively, and is included in other assets in the accompanying Unaudited Condensed Consolidated Balance Sheets. The following tables show debt securities available-for-sale in an unrealized loss position for which an allowance for credit losses has not been recorded, aggregated by investment category and length of time that the individual securities have been in a continuous unrealized loss position.

The evaluation considers the extent to which the security’s fair value is less than cost, the financial condition and near-term prospects of the issuer, and intent and ability of the Company to retain its investment in the security for a period of time sufficient to allow for any anticipated recovery in fair value. At September 30, 2022, there were one hundred twenty-eight mortgage-backed securities and one municipal bond in unrealized loss positions for greater than 12 months. There were six US government agency securities, two hundred eighty-three mortgage-backed securities, and one municipal bond in unrealized loss positions for less than 12 months. Unrealized losses at December 31, 2021 were comprised of thirty-one mortgage-backed securities and one municipal bond in unrealized loss positions for greater than 12 months, and one hundred forty-two mortgage-backed securities in unrealized loss positions for less than 12 months. These unrealized losses are primarily the result of non-credit-related volatility in the market and market interest rates. Since none of the unrealized losses relate to marketability of the securities or the issuers' ability to honor redemption obligations and the Company has the intent and ability to hold the securities for a sufficient period of time to recover unrealized losses, none of the losses have been recognized in the Company’s Unaudited Condensed Consolidated Statements of Income. All mortgage-backed securities in the Company’s portfolio at September 30, 2022 and December 31, 2021 were backed by U.S. government sponsored enterprises (“GSEs”). The following is a summary of investment securities by maturity: September 30, 2022 Available-for-Sale Amortized cost Fair value US government agencies Within one year $ 7,502 $ 7,494 One to five years 12,945 12,555 Total 20,447 20,049 Mortgage-backed securities One to five years 154,971 145,228 Five to ten years 208,714 181,882 After 10 years 742,830 654,731 Total 1,106,515 981,841 Municipal bonds After 10 years 3,229 2,982 Total 3,229 2,982 Other debt securities Within one year 500 500 Total 500 500 Total $ 1,130,691 $ 1,005,372 Mortgage-backed securities are included in maturity categories based on their contractual maturity date.

Loss rates are adjusted for twelve month forecasted unemployment followed by a twelve-month straight-line reversion period. During the three and nine month periods ended September 30, 2021, increases to the ACL were primarily related to loan growth which has outpaced the improvement in forecasted unemployment rates and other conditions related to the COVID-19 pandemic. Unemployment rates were forecasted for twelve months followed by a twelve-month straight-line reversion period. Additionally, the provision expense was impacted by net charge-offs during the periods.

Leases [Abstract]
Leases	Leases Lessor Equipment Leasing The Company purchases new equipment for the purpose of leasing such equipment to customers within its verticals. Equipment purchased to fulfill commitments to commercial renewable energy projects is rented out under operating leases while leases of equipment outside of the renewable energy vertical are generally direct financing leases. Accordingly, leased assets under operating leases are included in premises and equipment while leased assets under direct financing leases are included in loans and leases held for investment in the accompanying Unaudited Condensed Consolidated Balance Sheets. Direct Financing Leases Interest income on direct financing leases is recognized when earned. Unearned interest is recognized over the lease term on a basis which results in a constant rate of return on the unrecovered lease investment. The term of each lease is generally 3 to 7 years which is consistent with the useful life of the equipment with no residual value. The net investment in direct finance leases included in loans and leases held for investment are as follows: September 30, 2022 December 31, 2021 Gross direct finance lease payments receivable $ 4,872 $ 7,333 Less – unearned interest (565) (998) Net investment in direct financing leases $ 4,307 $ 6,335 Future minimum lease payments under finance leases are as follows: As of September 30, 2022 Amount 2022 $ 446 2023 1,945 2024 1,374 2025 990 2026 117 Total $ 4,872 Interest income of $101 thousand and $159 thousand was recognized in the three months ended September 30, 2022 and 2021, respectively. Interest income of $309 thousand and $517 thousand was recognized in the nine months ended September 30, 2022 and 2021, respectively. Operating Leases The term of each operating lease is generally 10 to 15 years. The Company retains ownership of the equipment and associated tax benefits such as investment tax credits and accelerated depreciation. At the end of the lease term, the lessee has the option to renew the lease for two additional terms or purchase the equipment at the then-current fair market value. Rental revenue from operating leases is recognized on a straight-line basis over the term of the lease. Rental equipment is recorded at cost and depreciated to an estimated residual value on a straight-line basis over the estimated useful life. The useful lives generally range from 20 to 25 years and residual values generally range from 20% to 50%, however, they are subject to periodic evaluation. Changes in useful lives or residual values will impact depreciation expense and any gain or loss from the sale of used equipment. The estimated useful lives and residual values of the Company's leasing equipment are based on industry disposal experience and the Company's expectations for future sale prices. If the Company decides to sell or otherwise dispose of rental equipment, it is carried at the lower of cost or fair value less costs to sell or dispose. Repair and maintenance costs that do not extend the lives of the rental equipment are charged to equipment expense at the time the costs are incurred. As of September 30, 2022 and December 31, 2021, the Company had a net investment of $116.6 million and $123.9 million, respectively, in assets included in premises and equipment that are subject to operating leases. Of the net investment, the gross balance of the assets was $163.4 million as of September 30, 2022 and December 31, 2021 and accumulated depreciation was $46.8 million and $39.5 million as of September 30, 2022 and December 31, 2021, respectively. Depreciation expense recognized on these assets for the three months ended September 30, 2022 and 2021 was $2.4 million. Depreciation expense recognized on these assets for the nine months ended September 30, 2022 and 2021 was $7.3 million. Lease income of $2.4 million was recognized in the three months ended September 30, 2022 and 2021. Lease income of $7.1 million and $7.2 million was recognized in the nine months ended September 30, 2022 and 2021, respectively. A maturity analysis of future minimum lease payments to be received under non-cancelable operating leases is as follows: As of September 30, 2022 Amount 2022 $ 1,960 2023 9,075 2024 8,808 2025 8,935 2026 8,923 Thereafter 22,253 Total $ 59,954

Transfers and Servicing [Abstract]
Servicing Assets	Servicing Assets Loans serviced for others are not included in the accompanying Unaudited Condensed Consolidated Balance Sheets. The unpaid principal balance of loans serviced for others requiring recognition of a servicing asset was $2.22 billion and $2.29 billion at September 30, 2022 and December 31, 2021, respectively. The unpaid principal balance for all loans serviced for others was $3.35 billion and $3.30 billion at September 30, 2022 and December 31, 2021, respectively. The following summarizes the activity pertaining to servicing rights: Three Months Ended Nine Months Ended 2022 2021 2022 2021 Balance at beginning of period $ 28,661 $ 36,966 $ 33,574 $ 33,918 Additions, net 1,744 2,880 7,068 7,616 Fair value changes: Due to changes in valuation inputs or assumptions 992 (2,768) (3,056) 119 Decay due to increases in principal paydowns or runoff (2,316) (3,110) (8,505) (7,685) Balance at end of period $ 29,081 $ 33,968 $ 29,081 $ 33,968 The fair value of servicing rights was determined using a weighted average discount rate of 15.1% on September 30, 2022 and 12.3% on September 30, 2021. The fair value of servicing rights was determined using a weighted average prepayment speed of 16.1% on September 30, 2022 and 16.7% on September 30, 2021, with the actual rate depending on the stratification of the specific right. Changes to fair value are reported in loan servicing asset revaluation within the Unaudited Condensed Consolidated Statements of Income. The fair value of servicing rights is highly sensitive to changes in underlying assumptions. Changes in prepayment speed assumptions typically have the most significant impact on the fair value of servicing rights. Generally, as interest rates rise on variable rate loans, loan prepayments increase due to an increase in refinance activity, which results in a decrease in the fair value of servicing assets, however, weakening economic conditions or significant declines in interest rates can also increase loan prepayment activity. Measurement of fair value is limited to the conditions existing and the assumptions used as of a particular point in time, and those assumptions may not be appropriate if they are applied at a different time.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair Value Hierarchy There are three levels of inputs in the fair value hierarchy that may be used to measure fair value. Financial instruments are considered Level 1 when valuation can be based on quoted prices in active markets for identical assets or liabilities. Level 2 financial instruments are valued using quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or models using inputs that are observable or can be corroborated by observable market data of substantially the full term of the assets or liabilities. Financial instruments are considered Level 3 when their values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable and when determination of the fair value requires significant management judgment or estimation. Recurring Fair Value The table below provides a rollforward of the Level 3 equity warrant asset fair values.

Fair Value of Financial Instruments in the Company’s 2021 Form 10-K. Fair Value Option The Company has historically elected to account for retained participating interests of all government guaranteed loans under the fair value option in order to align the accounting presentation with the Company’s viewpoint of the economics of the loans. Interest income is recognized in the same manner on loans reported at fair value as on non-fair value loans, except in regard to origination fees and costs which are recognized immediately upon fair value election. Beginning in the first quarter of 2021, the Company chose not to elect fair value for all retained participating interests arising from new government guaranteed loan sales. Not electing fair value generally results in a larger discount being recorded on the date of the sale. This discount is subsequently accreted into interest income over the underlying loan’s remaining term using the effective interest method. Management made this change of election in alignment with its ongoing effort to reduce volatility and drive more predictable revenue. In accordance with GAAP, any loans for which fair value was previously elected will continue to be measured as such. There were no loans accounted for under the fair value option that were 90 days or more past due and still accruing interest at September 30, 2022 or December 31, 2021. The unpaid principal balance of unguaranteed exposure for nonaccruals was $3.7 million and $6.9 million at September 30, 2022 and December 31, 2021, respectively. The following tables provide more information about the fair value carrying amount and the unpaid principal outstanding of loans accounted for under the fair value option at September 30, 2022 and December 31, 2021.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation In the normal course of business, the Company is involved in various legal proceedings. Management believes that the outcome of such proceedings will not materially affect the financial position, results of operations or cash flows of the Company. On March 12, 2021, a purported class action was filed against the Company in the United States District Court for the Eastern District of North Carolina, Joseph McAlear, individually and on behalf of all others similarly situated v. Live Oak Bancshares, Inc. et al. The complaint alleged the existence of an agreement between the Company, nCino, Inc. and Apiture, LLC in which those companies purportedly sought to restrain the mobility of employees in violation of antitrust laws by agreeing not to solicit or hire each other’s employees. The complaint alleged violations of Section 1 of the federal Sherman Act (15 U.S.C. § 1) and violations of Sections 75-1 and 75-2 of the North Carolina General Statutes. The plaintiff sought monetary damages, including treble damages, entitlement to restitution, disgorgement, attorneys’ fees, and pre- and post-judgment interest. On October 12, 2021, the Company reached an agreement to settle the case with a proposed class of all persons (with certain exclusions) employed by the Company or its wholly-owned subsidiary, Live Oak Banking Company, Apiture, Inc. or nCino, Inc. in North Carolina at any time from January 27, 2017, through March 31, 2021. In the agreement, the Company agreed to pay $3.9 million. On October 13, 2021, the plaintiff filed a motion for preliminary approval of the settlement, which the court granted by order entered on November 23, 2021. After class-wide noticing, the plaintiff filed a motion for final approval on March 28, 2022, which the court granted by order entered on April 28, 2022. Pursuant to the terms of the settlement, the settlement became effective on June 11, 2022. Financial Instruments with Off-Balance-Sheet Risk The Company is party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments involve, to varying degrees, credit risk in excess of the amount recognized in the balance sheet. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as for on-balance-sheet instruments. A summary of the Company’s commitments is as follows: September 30, December 31, Commitments to extend credit $ 2,927,606 $ 2,634,387 Standby letters of credit 25,912 10,753 Airplane purchase agreement commitments 30,000 — Total unfunded off-balance-sheet credit risk $ 2,983,518 $ 2,645,140 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the party. Collateral held varies, but may include accounts receivable, inventory, property and equipment, residential real estate and income-producing commercial properties. Commitment letters are issued after approval of the loan by the Credit Department and generally expire ninety days after issuance. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. Collateral held varies as specified above and is required in instances which the Company deems necessary. The allowance for off-balance sheet credit exposures was $1.1 million and $739 thousand at September 30, 2022 and December 31, 2021, respectively. As of September 30, 2022 and December 31, 2021, the Company recorded unfunded commitments to provide capital contributions for on-balance-sheet investments in the amount of $23.9 million and $10.4 million, respectively. Concentrations of Credit Risk The distribution of commitments to extend credit approximates the distribution of loans outstanding. The Company does not have a significant number of credits to any single borrower or group of related borrowers whereby their retained unguaranteed exposure exceeds $20.0 million, except for twenty-two relationships that have a retained unguaranteed exposure of $656.3 million of which $381.8 million of the unguaranteed exposure has been disbursed. Additionally, the Company has future minimum lease payments receivable under non-cancelable operating leases totaling $60.0 million, of which no relationships exceed $20.0 million. The Company from time-to-time may have cash and cash equivalents on deposit with financial institutions that exceed federally-insured limits.

Segment Reporting [Abstract]
Segments	Segments The Company's management reporting process measures the performance of its operating segments based on internal operating structure, which is subject to change from time to time. Accordingly, the Company operates two reportable segments for management reporting purposes as discussed below: Banking - This segment specializes in providing financing services to small businesses nationwide in targeted industries and deposit-related services to small businesses, consumers and other customers nationwide. The primary source of revenue for this segment is net interest income and secondarily the origination and sale of government guaranteed loans. Fintech - This segment is involved in making strategic investments into emerging financial technology companies. The primary sources of revenue for this segment are principally gains and losses on equity method and equity security investments and management fees. The Fintech segment is comprised of the Company's direct wholly owned subsidiaries Live Oak Ventures and Canapi Advisors, and the investments held by those entities, as well as the Bank's investment in Apiture.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	General In the opinion of management, all adjustments necessary for a fair presentation of the financial position and results of operations for the periods presented have been included, and all intercompany transactions have been eliminated in consolidation. Results of operations for the three and nine months ended September 30, 2022 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2022. The Unaudited Condensed Consolidated Balance Sheet as of December 31, 2021 has been derived from the audited consolidated financial statements contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, filed with the Securities Exchange Commission on February 24, 2022 (SEC File No. 001-37497) (the “ 2021 Form 10-K ” ). A summary description of the significant accounting policies followed by the Company is set forth in Note 1 of the Notes to Consolidated Financial Statements in the Company’s 2021 Form 10-K. These Unaudited Interim Condensed Consolidated Financial Statements should be read in conjunction with the audited consolidated financial statements and footnotes in the Company's 2021 Form 10-K. The preparation of financial statements in conformity with United States generally accepted accounting principles ( “ GAAP ” ) requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and the reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from those estimates. Amounts in all tables in the Notes to Unaudited Condensed Consolidated Financial Statements have been presented in thousands, except percentage, time period, share and per share data or where otherwise indicated.
Business Segments	Business Segments Operating segments are components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. Management has determined that the Company has two reportable operating segments: Banking and Fintech, as discussed more fully in Note 11. Segments. In determining the appropriateness of a segment definition, the Company considers the criteria of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 280, Segment Reporting .
Reclassifications	ReclassificationsCertain reclassifications have been made to the prior period’s Unaudited Condensed Consolidated Financial Statements to place them on a comparable basis with the current year. Net income and shareholders’ equity previously reported were not affected by these reclassifications
