Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	Live Oak Bancshares, Inc. Notes to Unaudited Condensed Consolidated Financial Statements Note 1. Basis of Presentation Nature of Operations Live Oak Bancshares, Inc. (the “Company” or “LOB”) is a bank holding company headquartered in Wilmington, North Carolina incorporated under the laws 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 providing lending services to small businesses nationwide. The Bank identifies and grows 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 ("USDA") Rural Energy for America Program ("REAP"), Water and Environmental Program (“WEP”) and Business & Industry ("B&I") loan programs. The Bank’s wholly owned subsidiaries are Live Oak Number One, Inc., Live Oak Clean Energy Financing LLC (“LOCEF”), and Live Oak Private Wealth, LLC. Live Oak Private Wealth, LLC’s wholly owned subsidiary is Jolley Asset Management, LLC (“JAM”). See Business Combination discussion below for more information on this new subsidiary. The Company’s wholly owned subsidiaries are the Bank, Government Loan Solutions (“GLS”), Live Oak Grove, LLC (“the Grove”), Live Oak Ventures, Inc. (“Live Oak Ventures”), and Canapi Advisors, LLC (“Canapi”). Live Oak Number One, Inc. holds properties foreclosed on by the Bank. LOCEF provides financing to entities for renewable energy applications and became a wholly owned subsidiary of the Bank during the first quarter of 2019. Live Oak Private Wealth, LLC and JAM provide high-net-worth individuals and families with strategic wealth and investment management services. 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 provides investment advisory services to a series of new funds focused on providing venture capital to new and emerging financial technology companies. The Company jointly formed 504 Fund Advisors, LLC (“504FA”) to serve as the investment adviser for the 504 Fund, a closed-end mutual fund organized to invest in SBA section 504 loans. 504FA exited as advisor for the 504 Fund in May 2019 and the Company subsequently dissolved this legal entity. 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. The Company elects to account for certain loans under the fair value option with interest reported in interest income and changes in fair value reported in the net gain (loss) on loans accounted for under the fair value option line item of the consolidated statements of income. Income from the sale of loans is comprised of loan servicing revenue and revaluation of related servicing assets along with net gains on sales of loans. 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 has less routinely generated gains and losses arising from its financial technology investments. 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 nine months ended September 30, 2020 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2020. The condensed consolidated balance sheet as of December 31, 2019 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, 2019, filed with the Securities Exchange Commission on February 27, 2020 (SEC File No. 001-37497) (the "2019 Annual Report"). 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 2019 Annual Report. These unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and footnotes in the Company's 2019 Annual Report. The preparation of financial statements in conformity with United States generally accepted accounting principles, or 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, stock option, share and per share data or where otherwise indicated. Business Segments Management has determined that the Company has one significant operating segment, which is providing a lending platform for small businesses nationwide. In determining the appropriateness of segment definition, the Company considers the materiality of a potential segment, the components of the business about which financial information is available, and components for which management regularly evaluates relative to resource allocation and performance assessment. Reclassifications Certain reclassifications have been made to the prior period’s 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. Current period reclassifications were primarily related to fair value presentation requirements for loans in which the fair value option had previously been elected and included a reclassification of amounts representing the credit component of the fair value discount that was previously reported as a component of the allowance for credit losses on loans and leases to be netted directly against loans and leases held for investment on the Company’s consolidated balance sheet. Amounts reclassified from the allowance for credit losses on loans and leases to net directly against total loans and leases held for investment was $20.0 million, as of December 31, 2019. In addition, the change in the credit component of the fair value discount was previously reported in the provision for loan and lease credit losses while the change in the liquidity component of the fair value discount was previously reported in the loan servicing asset revaluation in the consolidated statements of income, but both have now been reclassified to net gain (loss) on loans accounted for under the fair value option. Amounts reclassified from the provision for loan and lease credit losses and the loan servicing asset revaluation to net gain (loss) on loans accounted for under the fair value option were $(3.2) million and $4.3 million, respectively, for the three months ended September 30, 2019, and $(3.0) million and $8.9 million, respectively for the nine months ended September 30, 2019. The effect of the above discussed reclassifications on the consolidated balance sheet as of December 31, 2019 is reflected in the March 31, 2020 10-Q. The effect on the consolidated statements of income and consolidated statements of cash flows for each period are presented below: As Reported Reclassifications As Reclassified Consolidated Statement of Income for the three months ended September 30, 2019 Provision for loan and lease credit losses $ 7,160 $ (3,200 ) $ 3,960 Net interest income after provision for loan and lease credit losses 30,371 3,200 33,571 Loan servicing asset revaluation (859 ) (4,302 ) (5,161 ) Net gain (loss) on loans accounted for under the fair value option — 1,102 1,102 Total noninterest income 18,628 (3,200 ) 15,428 Net income 3,895 — 3,895 Consolidated Statement of Income for the nine months ended September 30, 2019 Provision for loan and lease credit losses $ 13,365 $ (2,962 ) $ 10,403 Net interest income after provision for loan and lease credit losses 88,706 2,962 91,668 Loan servicing asset revaluation (3,508 ) (8,938 ) (12,446 ) Net gain (loss) on loans accounted for under the fair value option — 5,976 5,976 Total noninterest income 46,356 (2,962 ) 43,394 Net income 11,202 — 11,202 Consolidated Statement of Cash Flows for the nine months ended September 30, 2019 Provision for loan and lease credit losses $ 13,365 $ (2,962 ) $ 10,403 Net decrease in servicing assets 10,058 — 10,058 Change in discount on unguaranteed loans (6,815 ) 6,815 — Net loss (gain) on loans accounted for under fair value option — (5,976 ) (5,976 ) Net cash used by operating activities (352,806 ) (2,123 ) (354,929 ) Loan and lease originations and principal collections, net (396,548 ) 2,123 (394,425 ) Net cash used by investing activities (581,983 ) 2,123 (579,860 ) As a result of the increase in number and diversification of the industry verticals that the Company serves, management also made changes effective in the second quarter of 2020 to the loan and lease classes used in the credit quality disclosures in Note 5. Loans and leases are now grouped in one of the following classes (also referred to as divisions): Small Business Banking, Specialty Lending, or Paycheck Protection Program. Small Business Banking includes loans to customers in verticals that generally have traditional loan structures. Specialty Lending includes loans to customers in verticals that generally have atypical ownership structures as well as complex collateral arrangements, underwriting requirements, and servicing needs. Paycheck Protection Program (“PPP”) includes all loans originated under the PPP pursuant to the Coronavirus Aid, Relief, and Economic Security Act’s (“CARES Act”) economic relief program and carry a 100% government guarantee. These loan and lease classes were determined based on industry risk characteristics and management’s method for monitoring credit risk and managing those lending divisions. There were no changes to the Company’s portfolio segments. Adoption of New Accounting Standard On January 1, 2020, the Company adopted Accounting Standards Update (“ASU”) No. 2016-13 “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”) along with its amendments, which replaces the incurred loss impairment methodology in current standards with the current expected credit loss methodology (“CECL”) and requires consideration of a broader range of information to determine credit loss estimates. ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. One such change is to require credit losses to be presented as an allowance rather than as a write-down on available-for-sale debt securities management does not intend to sell. The Company adopted Accounting Standards Codification (“ASC”) 326 using the modified retrospective method for all financial assets measured at amortized cost and off-balance-sheet credit exposures. Results for reporting periods beginning after January 1, 2020 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. The Company recorded a net increase to retained earnings of $822 thousand, comprised of a $1.3 million decrease in the allowance for credit losses combined with a $499 thousand increase in reserve on unfunded commitments, as of January 1, 2020 for the cumulative effect of adopting ASC 326. Allowance for Credit Losses – Loans and Leases Held for Investment The allowance for credit losses (“ACL”) is a valuation account that is deducted from, or added to, the amortized cost basis of loans and leases to present a net amount expected to be collected. The ACL excludes loans held for sale and loans accounted for under the fair value option. Loans and leases are charged-off against the ACL when management believes the uncollectibility of a loan or lease balance is confirmed. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. The Company’s ACL on loans and leases is estimated using relevant information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. The Company’s historical credit loss experience provides the basis for the estimation of expected credit losses. Management adjusts historical loss information for differences in current risk characteristics such as portfolio risk grading, delinquency levels, or portfolio mix as well as for changes in environmental conditions such as changes in unemployment rates. The ACL is measured on a pooled basis when similar risk characteristics are present in the portfolio. The Company has identified portfolio segments based on industry and whether the receivable is secured by real estate or another form of collateral. Additional information related to the portfolio segments can be found in the Company’s 2019 Form 10-K. Expected credit losses for pooled loans and leases are estimated using a discounted cash flow (“DCF”) methodology. Loans or leases that do not share risk characteristics are evaluated on an individual basis and are excluded from the pooled evaluation. This generally occurs when, based on current information and events, it is probable that the Company will be unable to collect all interest and principal payments due according to the originally contracted, or reasonably modified, terms of the loan or lease agreement. The Company has determined that loans and leases meeting the criteria defined below must be reviewed quarterly to determine if they should be evaluated for expected credit losses on an individual basis. • All commercial loans and leases classified substandard or worse. • Any loan or lease that is on nonaccrual, or any loan or lease that is delinquent greater than 90 days past due and still accruing interest. • Any loan or lease that meets the definition of a troubled debt restructuring (“TDR”). Expected credit losses are estimated over the contractual term of the loan or lease, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications unless management has a reasonable expectation at the reporting date that a TDR will be executed with an individual borrower or the extension or renewal options are included in the contract at the reporting date and are not unconditionally cancellable by the Company. When the ACL, for pooled or individually evaluated loans and leases, is estimated using the DCF method, the effective interest rate used to discount expected cash flows is adjusted for expected prepayments. Past due status of loans and leases is determined based on contractual terms. Loans and leases are placed in nonaccrual status and interest accrual is discontinued if they become 90 days delinquent or there is evidence that the borrower’s ability to make the required payments is impaired. When interest accrual is discontinued, all unpaid accrued interest is reversed. Management has made the accounting policy election to exclude accrued interest receivable on loans from the estimate of credit losses. A loan or lease is accounted for as a TDR if the Company, for reasons related to the borrower’s financial difficulties, restructures a loan or lease, and grants a concession to the borrower that it would not otherwise grant. A TDR typically involves a more than short-term modification of terms such as a reduction of the interest rate below the current market rate for a loan or lease with similar risk characteristics or the waiving of certain financial covenants without corresponding offsetting compensation or additional support. When management determines that foreclosure is probable or when the borrower is experiencing financial difficulty at the reporting date and repayment is expected to be provided substantially through the operation or sale of the collateral, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. Allowance for Credit Losses – Off-Balance Sheet Credit Exposures Expected credit losses on off-balance sheet credit exposures is estimated over the contractual period in which the Company is exposed to such losses, unless the obligation to extend credit is unconditionally cancellable. The estimate of off-balance sheet credit exposures includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated losses. The estimate is influenced by historical loss experience, adjusted for current risk characteristics, and economic forecasts. Allowance for Credit Losses – Available-for-Sale Securities When available-for-sale debt securities are in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. Available-for-sale debt securities that do not meet the aforementioned criteria are evaluated to determine whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected from the security is less than the amortized cost basis, a credit loss exists and an ACL is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. Changes in the ACL are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the allowance when management believes the uncollectibility of an available-for-sale security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Management has made the accounting policy election to exclude accrued interest receivable on available-for-sale debt securities from the estimate of credit losses. Available-for-sale securities are charged-off against the allowance or, in the absence of any allowance, written down through income when deemed uncollectible by management or when either of the aforementioned criteria regarding intent or requirement to sell is met. Common Stock On March 15, 2020, the Board of Directors of the Company authorized the repurchase of up to $20,000,000 in shares of the Company’s voting common stock from time to time through December 31, 2020 (the “Repurchase Program”). The Repurchase Program enables the Company to acquire shares through open market purchases or privately negotiated transactions, including through a Rule 10b5-1 plan, at the discretion of management and on terms (including quantity, timing, and price) that determines to be advisable. Actions in connection with the repurchase program will be subject to various factors, including the Company’s capital and liquidity positions, regulatory and accounting considerations, the Company’s financial and operational performance, alternative uses of capital, the trading price of the Company’s common stock, and market conditions. The repurchase program does not obligate the Company to acquire a specific dollar amount or number of shares and may be extended, modified, or discontinued at any time. There were no shares repurchased during the three and nine months ended September 30, 2020 Business Combination On April 1, 2020, the Company acquired 100% of the equity interests of JAM, a registered investment advisor based in Rocky Mount, North Carolina. Goodwill, intangible assets and contingent consideration of $1.8 million, $2.3 million and $2.1 million, respectively, have been recorded by the Company. Intangible assets are almost entirely comprised of customer relationships that are being amortized using the straight-line method over 15 years. As a result of this acquisition, the Bank's subsidiary Live Oak Private Wealth, LLC, expects to broaden service offerings to existing high-net-worth individuals and families, attract new clients from an expanded footprint and benefit from economies of scale. The acquisition did not materially impact the Company's financial position, results of operations or cash flows. Given the impact of the above acquisition was immaterial to the Company and its result of operations, pro forma information has not been included Long-Lived Asset Reclassified to Held for Sale During the third quarter of 2020, the Company determined to sell one of its aircraft as it looks to modify outreach practices while continuing to support origination activities and the needs of an expanding nationwide customer base. As a result of this determination, the Company began marketing the aircraft for sale and recorded an impairment of $1.0 million reflected in the three and nine months ended September 30, 2020 condensed consolidated statements of income in the "Other expense" line item. The Company expects the aircraft to sell within one year from the time marketing began. The carrying amount of the aircraft of $9.1 million is reflected in the September 30, 2020 condensed consolidated balance sheet in the "Other assets" line item. Any gain or loss associated with the sale of the aircraft will be recorded at the time of the sale.

During the three months ended September 30, 2019, four US government agencies totaling $14.3 million were sold resulting in a net gain of $87 thousand. During the nine months ended September 30, 2020, two US government agency matured at $4.5 million, one US Treasury note matured at $5.0 million, eighteen mortgage-backed securities totaling $24.4 million were sold resulting in a net gain of $1.3 million, and two municipal bonds totaling $5.2 million were sold resulting in a net gain of $620 thousand. During the nine months ended September 30, 2019, $900 thousand of one municipal bond was sold and four US government agencies totaling $14.3 million were sold resulting in a net gain of $92 thousand Accrued interest receivable on available-for-sale securities totaled $2.0 million and $1.6 million at September 30, 2020 and December 31, 2019, respectively, and is included in other assets in the accompanying 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, 2020, there were three mortgage-backed securities and one municipal bond in unrealized loss positions for greater than 12 months and twenty-four mortgage-backed securities in unrealized loss positions for less than 12 months. Unrealized losses at December 31, 2019 were comprised of twenty-two mortgage-backed securities and one municipal bond in unrealized loss positions for greater than 12 months and twenty 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 issuer’s 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 consolidated statements of income. All mortgage-backed securities in the Company’s portfolio at September 30, 2020 and December 31, 2019 were backed by U.S. government sponsored enterprises (“GSEs”). The following is a summary of investment securities by maturity: September 30, 2020 Amortized cost Fair value US government agencies Within one year $ 7,500 $ 7,586 One to five years 7,517 7,812 Five to ten years 2,924 3,108 Total 17,941 18,506 Mortgage-backed securities One to five years 8,801 9,244 Five to ten years 208,964 227,065 After 10 years 494,029 507,266 Total 711,794 743,575 Municipal bonds After 10 years 3,272 3,696 Total 3,272 3,696 Total $ 733,007 $ 765,777 The table above reflects contractual maturities. Actual results will differ as the loans underlying the mortgage-backed securities may repay sooner than scheduled. There were no securities pledged at September 30, 2020 or December 31, 2019.

Loans and Leases Held for Investment and Credit Quality	Note 5. Loans and Leases Held for Investment and Credit Quality As described in Note 1. Basis of Presentation, loan and lease classes were changed during the current period. Small Business Banking includes loans to customers in verticals that generally have traditional loan structures. Specialty Lending includes loans to customers in verticals that generally have atypical ownership structures as well as complex collateral arrangements, underwriting requirements, and servicing needs. Paycheck Protection Program includes all loans originated under the CARES Act’s economic relief program and carry a 100% government guarantee.

Leases [Abstract]
Leases	Note 6. 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. 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 3-7 years which is consistent with the useful life of the equipment with no residual value. The gross lease payments receivable and the net investment included in accounts receivable for such leases are as follows: September 30, 2020 December 31, 2019 Gross direct finance lease payments receivable $ 11,355 $ 13,959 Less – unearned interest (1,874 ) (2,562 ) Net investment in direct financing leases $ 9,481 $ 11,397 Future minimum lease payments under finance leases are as follows: As of September 30, 2020 Amount 2020 $ 763 2021 2,910 2022 2,665 2023 2,223 2024 1,580 Thereafter 1,214 Total $ 11,355 Interest income of $199 thousand and $244 thousand was recognized in the three months ended September 30, 2020 and 2019, respectively. Interest income of $644 thousand and $745 thousand was recognized in the nine months ended September 30, 2020 and 2019, 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.

Servicing Assets	Note 7. Servicing Assets Loans serviced for others are not included in the accompanying condensed consolidated balance sheets. The unpaid principal balances of loans serviced for others requiring recognition of a servicing asset were $2.27 billion and $2.26 billion at September 30, 2020 and December 31, 2019, respectively. The unpaid principal balance for all loans serviced for others was $3.14 billion and $2.97 billion at September 30, 2020 and December 31, 2019, respectively. The following summarizes the activity pertaining to servicing rights: Three Months Ended September 30, Nine Months Ended September 30, 2020 2019 2020 2019 Balance at beginning of period $ 33,834 $ 41,687 $ 35,365 $ 47,641 Additions, net 1,936 1,057 6,668 2,388 Fair value changes: Due to changes in valuation inputs or assumptions 3,758 (1,542 ) 1,596 (1,850 ) Decay due to increases in principal paydowns or runoff (1,697 ) (3,619 ) (5,798 ) (10,596 ) Balance at end of period $ 37,831 $ 37,583 $ 37,831 $ 37,583 The fair value of servicing rights was determined using a weighted average discount rate of 9.1% on September 30, 2020 and 14.1% on September 30, 2019. The fair value of servicing rights was determined using a weighted average prepayment speed of 19.1% on September 30, 2020 and 15.7% on September 30, 2019, depending on the stratification of the specific right. Changes to fair value are reported in loan servicing asset revaluation within the 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	Note 9. 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 following sections provide a description of the valuation methodologies used for instruments measured at fair value on a recurring basis, as well as the general classification of such instruments pursuant to the fair value hierarchy: Investment securities: Where quoted prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities would include highly liquid government bonds, mortgage products and exchange traded equities. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics, discounted cash flow or at net asset value per share. Level 2 securities would include U.S. government agency securities, mortgage-backed securities, obligations of states and political subdivisions and certain corporate, asset backed mutual fund and other securities. In certain cases where there is limited activity or less transparency around inputs to the valuation, securities are classified within Level 3 of the valuation hierarchy. Loans held for sale: The fair values of loans held for sale are determined by discounting estimated cash flows using interest rates approximating prevailing market rates for similar loans adjusted to reflect the inherent credit risk. Loans held for investment: The fair values of loans held for investment are typically determined based on discounted cash flow analyses using market-based interest rate spreads. Discounted cash flow analyses are adjusted, as appropriate, to reflect current market conditions and borrower-specific credit risk. If the loan is collateral dependent, the fair value is determined based on the difference between the fair value of the collateral and the amortized cost basis of the loan as of the measurement date. Fair value of the loan’s collateral is determined by appraisals, independent valuation, or management’s estimation of fair value which is then adjusted for the cost related to liquidation of the collateral. Servicing assets: Servicing rights do not trade in an active, open market with readily observable prices. While sales of servicing rights do occur, the precise terms and conditions typically are not readily available. Accordingly, the Company estimates the fair value of servicing rights using discounted cash flow models incorporating numerous assumptions from the perspective of a market participant including servicing income, servicing costs, market discount rates and prepayment speeds. Due to the nature of the valuation inputs, servicing rights are classified within Level 3 of the valuation hierarchy. Mutual fund: The following mutual fund is registered with the Securities and Exchange Commission as a closed-end, non-diversified management investment company and operates as an interval fund. The fund primarily invests in the unguaranteed portion of SBA504 First Lien Loans secured by owner-occupied commercial real estate. This investment is valued using quoted prices in markets that are not active and is classified as Level 2 within the valuation hierarchy. Equity warrant assets: Fair value measurements of equity warrant assets of private companies are priced based on a Black-Scholes option pricing model to estimate the asset value by using stated strike prices, option expiration dates, risk-free interest rates and option volatility assumptions. Option volatility assumptions used in the Black-Scholes model are based on public companies that operate in similar industries as the companies in the Company’s private company portfolio. Option expiration dates are modified to account for estimates to actual life relative to stated expiration. Values are further adjusted for a general lack of liquidity due to the private nature of the associated underlying company. The Company classifies equity warrant assets within Level 3 of the valuation hierarchy. The tables below present the recorded amount of assets and liabilities measured at fair value on a recurring basis.

A collateral dependent loan’s ACL is measured based on the difference between the fair value of the collateral and the amortized cost basis of the loan as of the measurement date. Fair value of the loan’s collateral is determined by appraisals, independent valuation, or management’s estimation of fair value which is then adjusted for the cost related to liquidation of the collateral. Collateral dependent loans are generally classified as Level 3 based on management’s judgment and estimation. Loans with agreed upon sales prices are classified as Level 1. Foreclosed assets: Foreclosed real estate is adjusted to fair value less selling costs upon transfer of the loans to foreclosed real estate. Subsequently, foreclosed real estate is carried at the lower of carrying value or fair value less selling costs. Fair value is based upon independent market prices, appraised values of the collateral or management’s estimation of the value of the collateral. Given the lack of observable market prices for identical properties and market discounts applied to appraised values, the Company generally classifies foreclosed assets as nonrecurring Level 3. Long-lived asset held for sale: Long-lived assets held for sale are carried at the lower of carrying value or fair value less selling costs. Fair value is based upon an independent market valuation of the property. Given the lack of observable market prices for identical assets and market discounts applied to market prices, the Company generally classifies long-lived assets held for sale as nonrecurring Level 3. Equity security investments with a non-readily determinable fair value: Equity security investments are measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. When an observable price change in an orderly transaction occurs for an identical investment of the same issuer, the investment is generally classified as nonrecurring Level 1 within the valuation hierarchy. When an observable price change in an orderly transaction occurs for a similar investment of the same issuer, the investment is generally classified as nonrecurring Level 2 within the valuation hierarchy. The tables below present the recorded amount of assets and liabilities measured at fair value on a non-recurring basis.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 10. 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. 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, 2020 December 31, 2019 Commitments to extend credit $ 1,810,114 $ 1,834,449 Standby letters of credit 27,197 25,532 Total unfunded off-balance-sheet credit risk $ 1,837,311 $ 1,859,981 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. In 2012, the Company began issuing commitment letters after approval of the loan by the Credit Department. Commitment letters 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. As of September 30, 2020 and December 31, 2019, the Company had unfunded commitments to provide capital contributions for on-balance-sheet investments in the amount of $14.7 million and $16.9 million, respectively. Concentrations of Credit Risk Although the Company is not subject to any geographic concentrations, a substantial amount of the Company’s loans, leases, and commitments to extend credit have been granted to customers in the agriculture, healthcare and veterinary verticals. The concentrations of credit by type of loan are set forth in Note 5. 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 $7.5 million, except for 38 relationships that have a retained unguaranteed exposure of $521.0 million of which $269.9 million of the unguaranteed exposure has been disbursed. Additionally, the Company has future minimum lease payments due under non-cancelable operating leases totaling $78.1 million, of which $56.1 million is due from four relationships. The Company from time-to-time may have cash and cash equivalents on deposit with financial institutions that exceed federally-insured limits.

Stock Plans	Note 11. Stock Plans On March 20, 2015, the Company adopted the 2015 Omnibus Stock Incentive Plan which replaced the previously existing Amended Incentive Stock Option Plan and Nonstatutory Stock Option Plan. Subsequently on May 24, 2016, the 2015 Omnibus Stock Incentive Plan was amended to authorize awards covering a maximum of 7,000,000 common voting shares and has an expiration date of March 20, 2025. On May 15, 2018, the Amended and Restated 2015 Omnibus Stock Incentive Plan was amended to authorize awards covering a maximum of 8,750,000 common voting shares. Options or restricted shares granted under the Amended and Restated 2015 Omnibus Stock Incentive Plan (the "Plan") expire no more than 10 years from the date of grant. Exercise prices under the Plan are set by the Board of Directors at the date of grant, but shall not be less than 100% of fair market value of the related stock at the date of the grant. Options vest over a minimum of three years from the date of the grant. Restricted stock grants vest in equal installments ranging from immediate vesting to over a seven year period from the date of the grant. Market Restricted Stock Units also have a restriction based on the passage of time and non-market-related performance criteria, but also have a restriction based on market price criteria related to the Company’s share price closing at or above a specified price defined at time of grant. Stock Options There were no stock options granted during the three and nine months ended September 30, 2020. At September 30, 2020, unrecognized compensation costs relating to stock options amounted to $2.8 million which will be recognized over a weighted average period of 1.87 years. Restricted Stock Restricted stock awards are authorized in the form of restricted stock awards or units ("RSU"s) and restricted stock awards or units with a market price condition ("Market RSU"s). RSUs have a restriction based on the passage of time and may also have a restriction based on a non-market-related performance criteria. The fair value of the RSUs is based on the closing price on the date of the grant. Market RSUs have a restriction based on the passage of time and non-market-related performance criteria, but also have a restriction based on market price criteria related to the Company’s share price closing at or above a specified price ranging from $34.00 to $55.00 per share for at least twenty (20) consecutive trading days at any time prior to expiration date. The amount of Market RSUs earned will not exceed 100% of the Market RSUs awarded. The fair value of the Market RSUs and the implied service period is calculated using the Monte Carlo simulation method. For the three months ended September 30, 2020, 39,999 RSUs were granted with a weighted average grant date fair value of $19.99. For the nine months ended September 30, 2020, 581,678 RSUs were granted with a weighted average grant date fair value of $17.57. Of the RSUs granted in the nine month period, 447,273 were awarded in connection with annual long term incentive stock compensation. At September 30, 2020, unrecognized compensation costs relating to RSUs amounted to $15.6 million which will be recognized over a weighted average period of 4.39 years. There were no Market RSUs granted during the three and nine months ended September 30, 2020. At September 30, 2020, unrecognized compensation costs relating to Market RSUs amounted to $8.8 million which will be recognized over a weighted average period of 2.92 years.

Equity Method Investments And Joint Ventures [Abstract]
Significant Equity Method Investments	Note 12. Significant Equity Method Investments In accordance with Rule 10-01(b)(1) of Regulation S-X, the Company must assess whether any of its equity method investments are significant equity method investments. In evaluating the significance of these investments, the Company performed the income test and the investment test described in S-X 3-05 and S-X 1-02(w). Rule 10-01(b)(1) of Regulation S-X requires summarized financial information in a quarterly report if any of the two tests exceeds 20%. The following table provides summarized balance sheet information for the Company’s equity method investments as of September 30, 2020 and December 31, 2019. The Company’s equity method investments are included in the other assets line on the condensed consolidated balance sheets and are largely concentrated in new or emerging financial service technology companies.

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 nine months ended September 30, 2020 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2020. The condensed consolidated balance sheet as of December 31, 2019 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, 2019, filed with the Securities Exchange Commission on February 27, 2020 (SEC File No. 001-37497) (the "2019 Annual Report"). 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 2019 Annual Report. These unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and footnotes in the Company's 2019 Annual Report. The preparation of financial statements in conformity with United States generally accepted accounting principles, or 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, stock option, share and per share data or where otherwise indicated.
Business Segments	Business Segments Management has determined that the Company has one significant operating segment, which is providing a lending platform for small businesses nationwide. In determining the appropriateness of segment definition, the Company considers the materiality of a potential segment, the components of the business about which financial information is available, and components for which management regularly evaluates relative to resource allocation and performance assessment.
Reclassifications	Reclassifications Certain reclassifications have been made to the prior period’s 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. Current period reclassifications were primarily related to fair value presentation requirements for loans in which the fair value option had previously been elected and included a reclassification of amounts representing the credit component of the fair value discount that was previously reported as a component of the allowance for credit losses on loans and leases to be netted directly against loans and leases held for investment on the Company’s consolidated balance sheet. Amounts reclassified from the allowance for credit losses on loans and leases to net directly against total loans and leases held for investment was $20.0 million, as of December 31, 2019. In addition, the change in the credit component of the fair value discount was previously reported in the provision for loan and lease credit losses while the change in the liquidity component of the fair value discount was previously reported in the loan servicing asset revaluation in the consolidated statements of income, but both have now been reclassified to net gain (loss) on loans accounted for under the fair value option. Amounts reclassified from the provision for loan and lease credit losses and the loan servicing asset revaluation to net gain (loss) on loans accounted for under the fair value option were $(3.2) million and $4.3 million, respectively, for the three months ended September 30, 2019, and $(3.0) million and $8.9 million, respectively for the nine months ended September 30, 2019. The effect of the above discussed reclassifications on the consolidated balance sheet as of December 31, 2019 is reflected in the March 31, 2020 10-Q. The effect on the consolidated statements of income and consolidated statements of cash flows for each period are presented below: As Reported Reclassifications As Reclassified Consolidated Statement of Income for the three months ended September 30, 2019 Provision for loan and lease credit losses $ 7,160 $ (3,200 ) $ 3,960 Net interest income after provision for loan and lease credit losses 30,371 3,200 33,571 Loan servicing asset revaluation (859 ) (4,302 ) (5,161 ) Net gain (loss) on loans accounted for under the fair value option — 1,102 1,102 Total noninterest income 18,628 (3,200 ) 15,428 Net income 3,895 — 3,895 Consolidated Statement of Income for the nine months ended September 30, 2019 Provision for loan and lease credit losses $ 13,365 $ (2,962 ) $ 10,403 Net interest income after provision for loan and lease credit losses 88,706 2,962 91,668 Loan servicing asset revaluation (3,508 ) (8,938 ) (12,446 ) Net gain (loss) on loans accounted for under the fair value option — 5,976 5,976 Total noninterest income 46,356 (2,962 ) 43,394 Net income 11,202 — 11,202 Consolidated Statement of Cash Flows for the nine months ended September 30, 2019 Provision for loan and lease credit losses $ 13,365 $ (2,962 ) $ 10,403 Net decrease in servicing assets 10,058 — 10,058 Change in discount on unguaranteed loans (6,815 ) 6,815 — Net loss (gain) on loans accounted for under fair value option — (5,976 ) (5,976 ) Net cash used by operating activities (352,806 ) (2,123 ) (354,929 ) Loan and lease originations and principal collections, net (396,548 ) 2,123 (394,425 ) Net cash used by investing activities (581,983 ) 2,123 (579,860 ) As a result of the increase in number and diversification of the industry verticals that the Company serves, management also made changes effective in the second quarter of 2020 to the loan and lease classes used in the credit quality disclosures in Note 5. Loans and leases are now grouped in one of the following classes (also referred to as divisions): Small Business Banking, Specialty Lending, or Paycheck Protection Program. Small Business Banking includes loans to customers in verticals that generally have traditional loan structures. Specialty Lending includes loans to customers in verticals that generally have atypical ownership structures as well as complex collateral arrangements, underwriting requirements, and servicing needs. Paycheck Protection Program (“PPP”) includes all loans originated under the PPP pursuant to the Coronavirus Aid, Relief, and Economic Security Act’s (“CARES Act”) economic relief program and carry a 100% government guarantee. These loan and lease classes were determined based on industry risk characteristics and management’s method for monitoring credit risk and managing those lending divisions. There were no changes to the Company’s portfolio segments.
Adoption of New Accounting Standard	Adoption of New Accounting Standard On January 1, 2020, the Company adopted Accounting Standards Update (“ASU”) No. 2016-13 “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”) along with its amendments, which replaces the incurred loss impairment methodology in current standards with the current expected credit loss methodology (“CECL”) and requires consideration of a broader range of information to determine credit loss estimates. ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. One such change is to require credit losses to be presented as an allowance rather than as a write-down on available-for-sale debt securities management does not intend to sell. The Company adopted Accounting Standards Codification (“ASC”) 326 using the modified retrospective method for all financial assets measured at amortized cost and off-balance-sheet credit exposures. Results for reporting periods beginning after January 1, 2020 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. The Company recorded a net increase to retained earnings of $822 thousand, comprised of a $1.3 million decrease in the allowance for credit losses combined with a $499 thousand increase in reserve on unfunded commitments, as of January 1, 2020 for the cumulative effect of adopting ASC 326. Allowance for Credit Losses – Loans and Leases Held for Investment The allowance for credit losses (“ACL”) is a valuation account that is deducted from, or added to, the amortized cost basis of loans and leases to present a net amount expected to be collected. The ACL excludes loans held for sale and loans accounted for under the fair value option. Loans and leases are charged-off against the ACL when management believes the uncollectibility of a loan or lease balance is confirmed. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. The Company’s ACL on loans and leases is estimated using relevant information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. The Company’s historical credit loss experience provides the basis for the estimation of expected credit losses. Management adjusts historical loss information for differences in current risk characteristics such as portfolio risk grading, delinquency levels, or portfolio mix as well as for changes in environmental conditions such as changes in unemployment rates. The ACL is measured on a pooled basis when similar risk characteristics are present in the portfolio. The Company has identified portfolio segments based on industry and whether the receivable is secured by real estate or another form of collateral. Additional information related to the portfolio segments can be found in the Company’s 2019 Form 10-K. Expected credit losses for pooled loans and leases are estimated using a discounted cash flow (“DCF”) methodology. Loans or leases that do not share risk characteristics are evaluated on an individual basis and are excluded from the pooled evaluation. This generally occurs when, based on current information and events, it is probable that the Company will be unable to collect all interest and principal payments due according to the originally contracted, or reasonably modified, terms of the loan or lease agreement. The Company has determined that loans and leases meeting the criteria defined below must be reviewed quarterly to determine if they should be evaluated for expected credit losses on an individual basis. • All commercial loans and leases classified substandard or worse. • Any loan or lease that is on nonaccrual, or any loan or lease that is delinquent greater than 90 days past due and still accruing interest. • Any loan or lease that meets the definition of a troubled debt restructuring (“TDR”). Expected credit losses are estimated over the contractual term of the loan or lease, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications unless management has a reasonable expectation at the reporting date that a TDR will be executed with an individual borrower or the extension or renewal options are included in the contract at the reporting date and are not unconditionally cancellable by the Company. When the ACL, for pooled or individually evaluated loans and leases, is estimated using the DCF method, the effective interest rate used to discount expected cash flows is adjusted for expected prepayments. Past due status of loans and leases is determined based on contractual terms. Loans and leases are placed in nonaccrual status and interest accrual is discontinued if they become 90 days delinquent or there is evidence that the borrower’s ability to make the required payments is impaired. When interest accrual is discontinued, all unpaid accrued interest is reversed. Management has made the accounting policy election to exclude accrued interest receivable on loans from the estimate of credit losses. A loan or lease is accounted for as a TDR if the Company, for reasons related to the borrower’s financial difficulties, restructures a loan or lease, and grants a concession to the borrower that it would not otherwise grant. A TDR typically involves a more than short-term modification of terms such as a reduction of the interest rate below the current market rate for a loan or lease with similar risk characteristics or the waiving of certain financial covenants without corresponding offsetting compensation or additional support. When management determines that foreclosure is probable or when the borrower is experiencing financial difficulty at the reporting date and repayment is expected to be provided substantially through the operation or sale of the collateral, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. Allowance for Credit Losses – Off-Balance Sheet Credit Exposures Expected credit losses on off-balance sheet credit exposures is estimated over the contractual period in which the Company is exposed to such losses, unless the obligation to extend credit is unconditionally cancellable. The estimate of off-balance sheet credit exposures includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated losses. The estimate is influenced by historical loss experience, adjusted for current risk characteristics, and economic forecasts. Allowance for Credit Losses – Available-for-Sale Securities When available-for-sale debt securities are in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. Available-for-sale debt securities that do not meet the aforementioned criteria are evaluated to determine whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected from the security is less than the amortized cost basis, a credit loss exists and an ACL is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. Changes in the ACL are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the allowance when management believes the uncollectibility of an available-for-sale security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Management has made the accounting policy election to exclude accrued interest receivable on available-for-sale debt securities from the estimate of credit losses. Available-for-sale securities are charged-off against the allowance or, in the absence of any allowance, written down through income when deemed uncollectible by management or when either of the aforementioned criteria regarding intent or requirement to sell is met.
Business Combination	Business Combination On April 1, 2020, the Company acquired 100% of the equity interests of JAM, a registered investment advisor based in Rocky Mount, North Carolina. Goodwill, intangible assets and contingent consideration of $1.8 million, $2.3 million and $2.1 million, respectively, have been recorded by the Company. Intangible assets are almost entirely comprised of customer relationships that are being amortized using the straight-line method over 15 years. As a result of this acquisition, the Bank's subsidiary Live Oak Private Wealth, LLC, expects to broaden service offerings to existing high-net-worth individuals and families, attract new clients from an expanded footprint and benefit from economies of scale. The acquisition did not materially impact the Company's financial position, results of operations or cash flows. Given the impact of the above acquisition was immaterial to the Company and its result of operations, pro forma information has not been included
Long-Lived Asset Reclassified to Held for Sale	Long-Lived Asset Reclassified to Held for Sale During the third quarter of 2020, the Company determined to sell one of its aircraft as it looks to modify outreach practices while continuing to support origination activities and the needs of an expanding nationwide customer base. As a result of this determination, the Company began marketing the aircraft for sale and recorded an impairment of $1.0 million reflected in the three and nine months ended September 30, 2020 condensed consolidated statements of income in the "Other expense" line item. The Company expects the aircraft to sell within one year from the time marketing began. The carrying amount of the aircraft of $9.1 million is reflected in the September 30, 2020 condensed consolidated balance sheet in the "Other assets" line item. Any gain or loss associated with the sale of the aircraft will be recorded at the time of the sale.
Common Stock
Equity	Common Stock On March 15, 2020, the Board of Directors of the Company authorized the repurchase of up to $20,000,000 in shares of the Company’s voting common stock from time to time through December 31, 2020 (the “Repurchase Program”). The Repurchase Program enables the Company to acquire shares through open market purchases or privately negotiated transactions, including through a Rule 10b5-1 plan, at the discretion of management and on terms (including quantity, timing, and price) that determines to be advisable. Actions in connection with the repurchase program will be subject to various factors, including the Company’s capital and liquidity positions, regulatory and accounting considerations, the Company’s financial and operational performance, alternative uses of capital, the trading price of the Company’s common stock, and market conditions. The repurchase program does not obligate the Company to acquire a specific dollar amount or number of shares and may be extended, modified, or discontinued at any time. There were no shares repurchased during the three and nine months ended September 30, 2020

Earnings Per Share [Abstract]
Computation of Basic and Diluted 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 be shared in the net income of the Company.
