Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Summary of Significant Accounting Policies	Organization and Summary of Significant Accounting Policies Organization Live Oak Banking Company (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. In December 2008, Live Oak Bancshares, Inc. (the “Company”) was formed and in the first quarter of 2009 acquired all the outstanding shares of Live Oak Banking Company. The Bank is headquartered in the city of Wilmington, North Carolina and has five satellite sales offices across the United States. The Bank specializes in providing lending and deposit related services to small businesses nationwide in targeted industries, which are referred to as verticals. The Bank identifies and grows within credit-worthy industries through expertise within 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 to a lesser extent by the U.S. Department of Agriculture ("USDA") Rural Energy for America Program ("REAP") and Business & Industry ("B&I") loan programs. The guaranteed portion of the loan is generally available for sale in the secondary market. From time to time the Bank also engages in the sale of participating interests of the unguaranteed portion. As a state chartered bank, the Bank is subject to regulation by the North Carolina Commissioner of Banks and the Federal Deposit Insurance Corporation. On July 23, 2015 the Company closed on its initial public offering with a secondary offering completed in August of 2017. In 2010, the Bank formed Live Oak Number One, Inc. to hold properties foreclosed on by the Bank. Live Oak Number One is a wholly-owned subsidiary of the Bank. In January 2012, the Company formed nCino, LLC (“nCino”) to further develop and sell cloud-based banking software that was built off of the Force.com platform and transformed into a bank operating system used to streamline the lending process of financial institutions. In 2012 nCino was a majority-owned subsidiary of the Company. In 2013 the Company’s ownership changed such that nCino became a minority-owned subsidiary of the Company. In December 2013 the legal structure of nCino converted from an LLC to a corporation. At year-end 2013, the Company owned 45.94% of nCino. In June of 2014 the Company divested its ownership in nCino to shareholders in the form of a dividend with a subsequent investment of $ 6.1 million later in 2014. At December 31, 2014, the Company owned 9.02% of nCino. During 2015, the Company sold its remaining investment in nCino resulting in no ownership as of December 31, 2015. In September 2013, the Company acquired Government Loan Solutions (“GLS”) as a wholly-owned subsidiary. GLS is a management and technology consulting firm that advises and offers solutions and services to participants in the government guaranteed lending sector. GLS, which was founded in 2006, 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. In December 2013, the Company jointly formed 504 Fund Advisors, LLC (“504FA”) with Pennant Management, Inc. (“Pennant Management”). As of December 31, 2014, 504FA was a 50% owned investment established for the purpose of underwriting and managing SBA 504 loans held by The 504 Fund (“the Fund”), formerly known as the Pennant 504 Fund. Two of the three portfolio managers of the Fund were employees of GLS. The third employee was an outside owner/manager of 504FA until April 30, 2015. The Company’s wholly owned subsidiaries, the Bank and GLS, provided various advisory and human resource services to 504FA, for which both were reimbursed. The services provided to 504FA did not result in either the Bank or GLS having the ability to directly influence management operations or decisions that directly impact the financial standing of the Company or its subsidiaries. Accordingly, the Company’s investment in 504FA was accounted for under the equity method at December 31, 2014, with a carrying amount of $ 231 thousand . The Company acquired control over 504FA on February 2, 2015 by increasing its ownership from 50.0% to 91.3% . The acquisition of an additional 41.3% of ownership occurred in exchange for contingent consideration estimated to total $ 170 thousand . Transactions in the third quarter of 2015 increased the Company’s ownership to 92.4% at December 31, 2015. With 7.6% of ownership remaining with a third party investor, amounts of earnings and equity in 504FA attributable to the third party investor were disclosed in the Company’s consolidated financial statements as related to a noncontrolling interest. During the first quarter of 2016, the Company increased ownership to 92.9% . On September 1, 2016, the Company acquired the remaining 7.1% ownership from a third party investor in exchange for contingent consideration estimated to total $24 thousand . The Company’s cumulative investment in 504FA was $ 1.4 million at December 31, 2017 and 2016 . In September 2015, the Company formed Live Oak Grove, LLC (“Grove”), a wholly-owned subsidiary, for the purpose of providing Company employees and business visitors an on-site restaurant location. In August 2016, the Company formed Canapi, Inc. (“Canapi”) for the purpose of investing in businesses that align with the Company's strategic initiative to be a leader in financial technology. Canapi was formerly known as Live Oak Ventures, Inc. In November 2016, the Company formed Live Oak Clean Energy Financing LLC for the purpose of providing financing to entities for renewable energy applications. On February 1, 2017, the Company completed its acquisition of Reltco Inc. and National Assurance Title, Inc. (collectively referred to as “Reltco”), two nationwide title agencies under common control based in Tampa, Florida. See Note 2. Title Insurance Business for a further discussion of this transaction. Basis of Presentation Dollar amounts in all tables in the Notes to Consolidated Financial Statements have been presented in thousands, except percentage, time period, stock option, share and per share data. The accounting and reporting policies of the Company and the Bank follow United States generally accepted accounting principles and general practices within the financial services industry. The following is a description of the significant accounting and reporting policies the Company follows in preparing and presenting its consolidated financial statements. Consolidation Policy The consolidated financial statements include the financial statements of the Company and wholly-owned subsidiaries of Live Oak Banking Company, Live Oak Number One, GLS, 504FA, Grove, Canapi, Live Oak Clean Energy Financing and Reltco. All significant intercompany balances and transactions have been eliminated in consolidation. In addition, the Company evaluates its relationships with other entities to identify whether they are variable interest entities and to assess whether it is the primary beneficiary of such entities. If the determination is made that the Company is the primary beneficiary, then that entity is included in the consolidated financial statements. If an entity is not a variable interest entity, the Company also evaluates arrangements in which there is a general partner or managing member to determine whether consolidation is appropriate. Unconsolidated investments where we have the ability to exercise significant influence over the operating and financial policies of the respective investee are accounted for using the equity method of accounting; those that are not consolidated or accounted for using the equity method of accounting are accounted for under cost or fair value accounting. For these investments accounted for under the equity method, the Company records its investment in non-consolidated affiliates and the portion of income or loss in equity in income of non-consolidated affiliates. The Company periodically evaluates these investments for impairment. On January 28, 2013, the Company’s ownership in nCino declined by 21.54% , from 64.36% to 42.82% . This decrease in ownership and related influence occurred as a result of nCino selling additional equity to outside investors for $ 7.5 million . As a result, the Company deconsolidated nCino, accounting for its remaining 42.82% investment using the equity method. As previously indicated, the Company divested its remaining ownership in nCino via a dividend to shareholders in June 2014. In August 2014 the Company again invested $ 6.1 million in nCino for 9.02% ownership. Due to the decreased level of influence, the Company’s investment in nCino at December 31, 2014 was accounted for as a cost method investment. During 2015, the Company sold its remaining investment in nCino resulting in no ownership as of December 31, 2015, 2016 and 2017. The Company expects to continue to be one of nCino’s customers; however, the power to direct nCino's activities is now controlled by outside investors. Variable Interest Entities Variable interests are defined as contractual ownership or other interests in an entity that change with fluctuations in an entity's net asset value. The primary beneficiary consolidates the variable interest entity ("VIE"). The primary beneficiary is defined as the enterprise that has both the power to direct the activities of the VIE that most significantly impact the entity's economic performance and the obligation to absorb losses or the right to receive benefits that could be significant to the VIE. The Company has a limited interest in a partnership that owns and operates a solar renewable energy project which is accounted for as an equity method investment. Over the course of the investment, the Company will receive federal and state tax credits, tax-related benefits, and excess cash available for distribution, if any. The Company may be called to sell its interest in the limited partnerships through a call option once all investment tax credits have been recognized. This entity meets the criteria of a VIE; however, the Company is not the primary beneficiary of the entities, as the general partner has both the power to direct the activities that most significantly impact the economic performance of the entities and the obligation to absorb losses or the right to receive benefits that could be significant to the entity. While the partnership agreement allows the Company to remove the general partner, this right is not deemed to be substantive as the general partner can only be removed for cause. The Company’s investments in the unconsolidated VIE is carried in other assets on the consolidated balance sheet and the Company’s unfunded capital and other commitments related to the unconsolidated VIE is carried in other liabilities on the consolidated balance sheet. The Company’s maximum exposure to loss from this unconsolidated VIE includes the investment recorded on the Company’s consolidated balance sheet, net of unfunded capital commitments and any impairment recognized, and previously recorded tax credits which remain subject to recapture by taxing authorities based on compliance features required to be met at the project level. While the Company believes the potential for losses from this investment is remote, the maximum exposure was determined by assuming a scenario where related tax credits were recaptured. The following table provides a summary of the tax advantaged VIE that the Company has not consolidated as of December 31, 2017 and 2016 : 2017 2016 Investment carrying amount $ 705 $ 1,394 Unfunded capital — 690 Maximum exposure to loss 4,221 5,100 Business Combinations Business combinations are accounted for by applying the acquisition method in accordance with Accounting Standards Codification (ASC) 805, Business Combinations. Under the acquisition method, identifiable assets acquired and liabilities assumed, and any non-controlling interest in the acquiree at the acquisition date are measured at their fair values as of that date, and are recognized separately from goodwill. Results of operations of the acquired entities are included in the consolidated statements of comprehensive income from the date of acquisition. Any measurement-period adjustments are recorded in the period the adjustment is identified. 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 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. Initial and Secondary Public Offerings The Company qualifies as an “emerging growth company” as defined by the Jumpstart Our Business Startups Act (JOBS Act). In April of 2015 the Company filed a Registration Statement on Form S-1 with the U.S. Securities and Exchange Commission (SEC). This Registration Statement was declared effective by the SEC on July 22, 2015. In reliance on that Registration Statement, the Company issued 5,500,000 shares of voting common stock, no par value, at $ 17.00 per share, in exchange for total proceeds of $ 87.2 million , net of issue costs. In August of 2017, the Company completed a secondary offering by issuing 5,175,000 shares of voting common stock, no par value, at $ 23.00 per share, in exchange for total proceeds of $ 113.1 million , net of issuance costs. The secondary offering was made pursuant to a prospectus supplement dated August 8, 2017 and an accompanying prospectus dated July 28, 2017, pursuant to the Company’s shelf registration statement on Form S-3 that was filed with the Securities and Exchange Commission and became effective on July 28, 2017. Use of Estimates In preparing financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”), management is required to make estimates and assumptions that affect reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan and lease losses, valuations of servicing assets and income taxes. In addition, the gain on contribution to equity method investment of $68.0 million was based on management's estimates, including projected cash flows of the entity, and is inherently subjective by its nature. Cash and Cash Equivalents For the purpose of presentation in the statement of cash flows, cash and cash equivalents are defined as those amounts included in the balance sheet caption “cash and due from banks.” Cash and cash equivalents have initial maturity of three months or less. To comply with banking regulations, the Company is required to maintain certain average cash reserve balances. The daily average cash reserve requirement was approximately $6.6 million and $ 1.3 million for the years ended December 31, 2017 and 2016 , respectively. Certificates of Deposit with other Banks Certificates of deposit with other banks have maturities ranging from March 2018 through December 2018 and bear interest at rates ranging from 0.15% to 1.90% . None of the certificates of deposit had maturities of 12 months or less at the time of origination. All investments in certificates of deposit are with FDIC insured financial institutions and none exceed the maximum insurable amount of $250 thousand. Investments Securities Certain debt securities that management has the positive intent and ability to hold to maturity are classified as “held-to-maturity” and recorded at amortized cost. Trading securities are recorded at fair value with changes in fair value included in earnings. Securities not classified as held-to-maturity or trading, are classified as “available-for-sale” and recorded at fair value. Unrealized gains and losses for available-for-sale investment securities are excluded from earnings and reported in other comprehensive income. The Company’s entire portfolio for the periods presented is available-for-sale. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Other The Company accounts for other investments either under the equity or cost method. Investments through which there is significant influence but not control over the investee are accounted for under the equity method. Investments through which the Company is not able to exercise significant influence over the investee are accounted for under the cost method. Other investments are generally non-marketable equity investments and are included in the other assets line on the consolidated balance sheet. Impairment At each reporting date, the Company evaluates each investment in a loss position for other than temporary impairment (“OTTI”). The Company evaluates declines in market value below cost for debt securities by assessing the likelihood of selling the security prior to recovering its cost basis. If the Company intends to sell the debt security or it is more-likely-than-not that the Company will be required to sell the debt security prior to recovering its cost basis, the Company will write down the security to fair value with the full charge recorded in earnings. If the Company does not intend to sell the debt security and it is not more-likely-than-not that the Company will be required to sell the debt security prior to recovery, the security will not be considered other-than-temporarily impaired unless there are credit losses associated with the security. In that case: (1) where credit losses exist, the portion of the impairment related to those credit losses should be recognized in earnings; (2) any remaining difference between the fair value and the cost basis should be recognized as part of other comprehensive income. For equity securities, any OTTI is recognized with the full charge recorded in earnings. To determine whether an impairment of equity securities is OTTI, the Company considers whether it has the ability and intent to hold the investment until there is a market price recovery and considers whether evidence indicating the cost of the investment is recoverable outweighs evidence to the contrary. In determining whether OTTI exists, management considers many factors, including (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. Gains and losses on the sales of securities are recorded on the trade date and are determined using the specific identification method. Loans Held For Sale Management designates loans as held for sale ("HFS") based on its intent to sell guaranteed portions in the SBA and USDA Secondary Market and unguaranteed portions to participant banks and credit unions. Salability requirements of the guaranteed portion include, but are not limited to, full disbursement of the loan commitment amount. Loans originated and intended for sale are carried at the lower of cost or estimated fair value on a loan-by-loan basis. The cost basis of loans held for sale includes the deferral of loan origination fees and costs. Deferred fees and costs are accreted and amortized for loans classified held for sale until the sale occurs. At loan settlement, the pro-rata portion, based on the percent of the total loan sold, of the remaining deferred fees and costs are recognized as an adjustment to the gain on sale. As part of our management of the loans held in our portfolio, we will occasionally transfer loans from held for investment to held for sale. Upon transfer, any associated allowance for loan and lease loss is released and the carrying value of the loans is adjusted to the estimated fair value. The loans are subsequently accounted for at the lower of cost or fair value, with valuation changes recorded in other noninterest income. Gains or losses on the sale of these loans are also recorded in noninterest income. In certain circumstances, loans designated as held for sale may later be transferred back to the loan and lease portfolio based upon our intent and ability to hold the loans for the foreseeable future. The Company transfers these loans to loans and leases held for investment at the lower of cost or fair value and establishes a related allowance for loan and lease loss. In accordance with SBA regulation, the Bank is required to retain 10% of the principal balance of any SBA 7(a) loan comprised of unguaranteed dollars. With written consent from the SBA, the Bank may sell down to a 5% exposure comprised of unguaranteed dollars. During 2012, the SBA approved the Bank to sell to the 5% retention level participating interests of the unguaranteed portion of loans originated on or before June 30, 2012 that had been fully funded for a period of eighteen months. This approval expired on June 30, 2014. Historically, loans held for sale consisted only of guaranteed loan balances and the unguaranteed portion up to the SBA retention minimums discussed above. A negative change in the credit quality of a loan resulted in the loan classification changing from held for sale to held for investment. Beginning in June 2016, loans held for sale consist of guaranteed loan balances. The gain on sale recognized in income is the sum of the premium on the guaranteed loan and the fair value of the servicing assets recognized, less the discount recorded on the unguaranteed portion of the loan retained. The following summarizes the activity pertaining to loans held for sale for the years ended December 31, 2017 and 2016 : 2017 2016 Balance at beginning of year $ 394,278 $ 480,619 Originations 1,149,617 1,013,643 Proceeds from sale (883,366 ) (837,830 ) Gain on sale of loans 78,590 75,326 Principal collections, net of deferred fees and costs (14,556 ) (209 ) Non-cash transfers, net (44,109 ) (337,271 ) Balance at end of period $ 680,454 $ 394,278 Loans and Leases Held for Investment Loans and leases receivable that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are classified as held for investment ("HFI") and reported at their outstanding principal amount adjusted for any charge-offs, the allowance for loan and lease losses, and any deferred fees or costs on originated loans and leases and unamortized premium or discount on purchased loans. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method. Discounts and premiums on any purchased loans are amortized to income using the interest method over the remaining period to contractual maturity, adjusted for anticipated prepayments. Historically, loans and leases designated as held for investment, included loans and leases identified as more beneficial to hold for the long term as well as the required retention amount defined by the SBA comprised of unguaranteed dollars and loans and leases designated as troubled debt restructurings, nonaccrual, and risk grade at a 5 or worse as defined by internal risk rating metrics. Beginning June 2016, loans and leases held for investment consist of unguaranteed loan and lease balances and guaranteed and unguaranteed loans and leases designated as troubled debt restructurings, nonaccrual, non-marketable, and risk grade 5 or worse. During the second quarter of 2016, the Bank transferred $318.8 million in unguaranteed loans from the HFS category to the HFI category to better reflect intentions of the Company. Interest income on loans and leases is recognized as earned on a daily accrual basis. The accrual of interest on loans and leases is discontinued when principal or interest is past due 90 days or the loan or lease is determined to be impaired. Impaired loans and leases, or portions thereof, are charged off when deemed uncollectible. 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 leased 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 4 - 6 years which is consistent with the useful life of the equipment with no residual value. As of December 31, 2017, the Company had net investments in direct financing lease receivables of $ 2.0 million . 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 40% , 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 direct operating expenses at the time the costs are incurred. As of December 31, 2017, the Company had a net investment of $ 88.4 million in assets included in premises and equipment that are subject to operating leases. A maturity analysis of future minimum lease payments under non-cancelable operating leases is as follows: As of December 31, 2017 Amount 2018 $ 5,162 2019 5,408 2020 5,428 2021 5,455 2022 5,458 Thereafter 34,046 Total $ 60,957 Allowance for Loan and Lease Losses The allowance for loan and lease losses is established as losses are estimated to have occurred through a provision for loan and lease losses charged to earnings. Loan or lease losses are charged against the allowance when management believes the un-collectibility of a loan or lease balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan and lease losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectibility of the loans or leases in light of historical experience, the nature and volume of the loan and lease portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. A loan or lease is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan or lease agreement. Factors considered by management in determining impairment include payment status and other circumstances impacting the probability of collecting scheduled principal and interest payments when due. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan or lease and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a credit-by-credit basis by either the present value of expected future cash flows discounted at the loan or lease's effective interest rate, the loan or lease’s obtainable market price, or the fair value of the collateral if the loan or lease is collateral dependent, except for large groups of smaller balance homogeneous loans or leases which are collectively evaluated for impairment. Smaller balance loan or lease relationships collectively evaluated for impairment are generally comprised of credits with unguaranteed exposure of less than $100,000 using a methodology based on historical specific reserves on similar sized loans or leases. Loans or leases classified as troubled debt restructured (“TDR”) are considered impaired. Loans or leases that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. 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 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. The Company measures the impairment loss of a TDR using the methodology for individually impaired loans or leases. Interest is accrued and credited to income based on the principal amount outstanding. The accrual of interest on impaired loans or leases is discontinued when, in management’s opinion, the borrower may be unable to meet payments as they become due or when the loan or lease becomes ninety days past due. Past due status of loans and leases is determined based on contractual terms. When interest accrual is discontinued, all unpaid accrued interest for the current year is reversed. Interest income is subsequently recognized on the cash-basis or cost-recovery method, as appropriate. Cash payments of interest on nonaccrual loans or leases will be applied to the principal balance of the loan or lease. When facts and circumstances indicate the borrower has regained the ability to meet the required payments, the loan or lease is returned to accrual status. Interest accruals are resumed on nonaccrual loans or leases only when it is brought current with respect to interest and principal and when, in the judgment of management, the loans or leases are estimated to be fully collectible as to all principal and interest. Management’s judgment is based on an assessment of the borrower’s financial condition and a recent history of payment performance. The Company identifies all impaired loans and leases, including those individually and collectively evaluated for impairment, for impairment disclosures. Upon transfer from held for sale classification, loans and leases held for investment become subject to the allowance for loan and lease loss review process. As a result of this process, the above mentioned $318.8 million loan reclassification resulted in a $4.0 million increase in the provision for loan and lease losses during the second quarter of 2016. During the second quarter of 201

Business Combinations [Abstract]
Title Insurance Business	Title Insurance Business Business Combination On February 1, 2017, the Company completed its acquisition of Reltco, Inc. and National Assurance Title, Inc. (collectively referred to as "Reltco"), two nationwide title agencies under common control based in Tampa, Florida. The acquisition continues the Company's growth strategy, including vertically integrating with complementary services to deliver a high-quality customer experience with speed. On the acquisition date, the fair value of Reltco included $ 5.8 million in assets and $ 4.7 million in liabilities. The total acquisition gross consideration at the time of the transaction, including earn-out contingent consideration was approximately $ 15.8 million . The acquisition was valued at $ 12.7 million after consideration of the applicable fair value adjustments to the earn-out, resulting in the Company paying $ 7.8 million in cash and issuing 27,724 shares of its common stock at closing in addition to an earn-out of up to 184,012 shares of its stock and $ 3.8 million in cash, in exchange for all of the outstanding shares of Reltco. The earn-out was recorded as a $ 4.3 million contingent liability on the acquisition date and is earned proportionally based on the ratio of the new subsidiary's actual future aggregate net income after tax divided by a target net income after tax of approximately $ 6.0 million over the four year earn-out period. Fair value measurement of the earn-out was calculated using the Monte Carlo Simulation. The Monte Carlo Simulation simulates 100,000 trials to assess the expected market price as of the earn-out measurement date at the end of each of the next four years based on the Cox, Ross & Rubinstein option pricing methodology. The Monte Carlo Simulation utilized various assumptions that include a risk free rate of return through the end of each measurement period equivalent to that of a U.S. Treasury, expected volatility of 30.00% over four years and a dividend yield of 0.40% . The merger was accounted for in accordance with the acquisition method of accounting, and the identifiable assets acquired and liabilities assumed were recorded at their estimated fair values as of the acquisition date separately from goodwill. The estimated fair values of assets acquired and liabilities assumed are based on the information available at the date of the acquisition. Management continues to evaluate these fair values, which are subject to revision as additional information becomes available. Contingent consideration is recorded at fair value based on the terms of the purchase agreement with subsequent quarterly changes in fair value recorded through earnings. The fair value of contingent consideration upon acquisition was $ 4.3 million and increased by $ 350 thousand during the period leading up to the October 31, 2017 impairment assessment date discussed below. During this pre-impairment assessment period fair value was estimated using the Monte Carlo Simulation. The assumptions utilized include a risk-free rate of return through the end of each measurement period equivalent to that of a U.S. Treasury, expected volatility of 30.00% over the remaining 3.25 years and a dividend yield of 0.51% . The following table summarizes the allocation of the purchase price on the date of acquisition to assets acquired and the liabilities assumed based on their estimated fair values: Fair value of assets acquired Cash $ 102 Accounts receivable 159 Intangible assets 5,505 Total assets acquired 5,766 Fair value of liabilities assumed Contingent consideration 4,300 Accounts payable and other liabilities 381 Total liabilities assumed 4,681 Net assets acquired $ 1,085 Purchase price Common shares issued 27,724 Purchase price per share of the Company’s common stock $ 20.38 Company common stock issued 565 Cash $ 7,798 Total purchase price 8,363 Goodwill $ 7,278 Goodwill recorded represents future revenues and efficiencies gained through the Reltco acquisition. Goodwill in this transaction is expected to be deductible for income tax purposes. At the date of acquisition, intangible assets consisted of trade names of $ 1.2 million , customer relationships of $ 3.9 million , and non-compete agreements of $ 405 thousand . The Company recorded merger expenses of $ 766 thousand and $ 115 thousand during the years ended December 31, 2017 and 2016, respectively, related to the Reltco acquisition. Goodwill and Intangible Asset Impairment Goodwill and intangible assets are evaluated for potential impairment annually or when circumstances indicate potential impairment may have occurred. Impairment losses, if any, are determined based upon the excess of carrying value over the estimated fair value of the asset. As of October 31, 2017 the Company determined that its goodwill and certain intangible assets related to the Reltco business combination had indications of impairment. Reltco’s financial performance was significantly lower during the first nine-months of operations and expectations of future profitability for the reporting unit were also lower than originally expected due to a slowing of refinance activity in the mortgage industry. The slowing of refinance activity in the mortgage industry was largely driven by increased levels of market rates during 2017. In performing the goodwill impairment testing and measurement process to identify possible impairment, the estimated fair value of the Reltco reporting unit was developed using the income and market approaches to value Reltco. The income approach consisted of discounting projected long-term future cash flows, which are derived from internal forecasts and economic expectations for Reltco. The market valuation approach utilized revenue and EBITDA multiples from comparable market transactions. The results of the impairment test indicated that the estimated fair value of Reltco was less than book value which resulted in a goodwill impairment charge of $ 7.3 million in accordance with accounting for Intangibles, Goodwill and other under ASC 360. This non-cash goodwill impairment charge to earnings was recorded as a component of impairment expense on goodwill and other intangibles in the consolidated statement of income. While the intangibles subject to amortization were determined to be recoverable based on an undiscounted cash flow analysis, impairment of $ 720 thousand was realized for indefinite life tradenames. This non-cash intangible impairment charge to earnings was recorded as a component of impairment expense on goodwill and other intangibles in the consolidated statement of income. The following is a summary of activity in goodwill for the Reltco reporting unit: Balance, December 31, 2016 $ — Goodwill acquired during 2017 7,278 Accumulated impairment losses (7,278 ) Balance, December 31, 2017 $ — As a result of Reltco’s results of operations and the direct contractual inclusion of impairment losses in the determination of earn out consideration, the fair value of the contingent consideration decreased by $ 4.4 million , which is recorded as a component of impairment expense on goodwill and other intangibles in the consolidated statement of income. The Company subsequently modified the acquisition contract to change the definition of net income related to the earn-out contingent consideration which resulted in $ 1.6 million in salaries and employee benefit expense. Following is a summary of activity in contingent consideration for the Reltco reporting unit: Balance, December 31, 2016 $ — Contingent consideration recorded upon acquisition 4,300 Fair value adjustments prior to October 31, 2017 impairment assessment 350 Impact of impairment assessment (4,350 ) Effect of purchase contract modification 1,600 Balance, December 31, 2017 $ 1,900 Fair value of contingent consideration was estimated using the Monte Carlo Simulation. The assumptions utilized in the determining the impact of the impairment assessment and subsequent purchase contract modification include a risk-free rate of return through the end of each measurement period equivalent to that of a U.S. Treasury, expected volatility of 25.00% over the remaining 3.00 years and a dividend yield of 0.51% . Pro Formas The following pro forma financial information reflects the Company's estimated consolidated pro forma results of operations as if the Reltco acquisition occurred on January 1, of each of the below years: 2017 2016 2015 Revenue (net interest income and noninterest income) $ 251,723 $ 148,322 $ 116,582 Net income available to common shareholders 100,537 15,363 21,451 Basic earnings per share 2.75 0.45 0.69 Diluted earnings per share 2.66 0.44 0.67

Equity Method Investments and Joint Ventures [Abstract]
Unconsolidated Joint Venture	Unconsolidated Joint Venture On October 1, 2017, the Company closed the digital banking joint venture between Live Oak Banking Company and First Data Corporation ("First Data"). The new company, named Apiture, combines First Data's and the Bank's digital banking platforms, products, services, and certain human resources used in the creation and delivery of technology solutions for financial institutions. The contributed assets of both the Company and First Data are considered businesses in accordance with relevant accounting standards. At closing both the Bank and First Data received equal voting interests in Apiture in exchange for their respective contributions. As a term of the closing agreements, First Data is entitled to a preference in Apiture's cash earnings from the date of closing through December 31, 2017 and all of 2018, not to exceed $ 18.0 million and $ 18.9 million , respectively. As a result of this transaction, the Company and First Data each have, directly or indirectly, equal voting interests in Apiture. In addition, the Company has analyzed the Contribution Agreement and determined that Apiture is not a variable interest entity. The Company also considered the partners' participating rights under the Contribution Agreement and determined that the joint venture partners have the ability to participate in major decisions, which equates to shared decision making. Accordingly, the Bank has significant influence but does not control the joint venture. Therefore, the joint venture will be accounted for as an equity method investment effective on October 1, 2017 (the date of the transaction). Under the equity method of accounting, the net equity investment of the Bank and the Bank's share of net income or loss from the unconsolidated entity will be reflected in the Company's consolidated balance sheets and the consolidated statements of income. The estimated fair value of Apiture at the date of closing was approximately $ 150 million . Based on the aforementioned cash earnings preference to First Data during 2017 and 2018, the valuation of equity interests received in exchange for contributions by the two initial investors was unequal. As a consequence of this preference the initial economic interest in Apiture for First Data was equal to 54.7% or $ 82.0 million , while the Company's initial economic interest in Apiture was equal to 45.3% , or $ 68.0 million . As the Company had no carrying amount for its contribution in the formation of Apiture, the transaction resulted in the recognition of a $ 68.0 million equity method investment included in other assets on the consolidated balance sheet and a one-time pre-tax gain of the same amount reflected in gain on contribution to equity method investment on the consolidated income statement at the date of closing. The estimated fair value of Apiture and the related initial economic interests of investors were based on a discounted cash flows which are inherently subjective by nature. As a result of unequal economic interests arising from the cash earnings preference, distribution rights and priorities set forth in the Contribution Agreement differ from what is reflected by the underlying percentage voting interests of First Data and Live Oak. Accordingly, GAAP income (loss) is allocated utilizing the hypothetical liquidation at book value ("HLBV") method. Under the HLBV method, in which we allocate income or loss based on the change in each unitholders’ claim on the net assets of Apiture at period end, after adjusting for any distributions or contributions made during such period. The HLBV method is commonly applied to equity investments where cash distribution percentages vary at different points in time and are not directly linked to an equity holder’s ownership percentage. The HLBV method is a balance sheet-focused approach. A calculation is prepared at each balance sheet date to determine the amount that unitholders would receive if Apiture were to liquidate all of its assets (at GAAP net book value) and distribute the resulting proceeds to its creditors and unitholders based on the contractually defined liquidation priorities. The difference between the calculated liquidation distribution amounts at the beginning and the end of the reporting period, after adjusting for capital contributions and distributions, is used to derive each unitholder's share of the income (loss) for the period. Due to the stated cash earnings preference to First Data and because the HLBV method incorporates non-cash items such as amortization expense, in any given period, income or loss may be allocated disproportionately to unitholders as compared to their respective ownership percentage in our operating partnership, and net income (loss) attributable to the Bank could be more or less net income than actual cash distributions received and more or less income or loss than what may be received in the event of an actual liquidation. Additionally, the HLBV method could result in no net income attributable to the Company during a period when Apiture reports net income.

During the year ended December 31, 2016 , one security was sold for $1.9 million resulting in a net gain of $1 thousand . Twelve securities were sold for $ 17.7 million resulting in a net gain on sale of securities of $ 13 thousand during the year ended December 31, 2015 .

Unrealized losses at December 31, 2016 consisted of two residential mortgage-backed securities in unrealized loss positions for greater than 12 months and three US government agency securities, twenty-two residential mortgage-backed securities and the 504 Fund mutual fund investment in unrealized loss positions for less than 12 months. These unrealized losses are primarily the result of volatility in the market and are related to 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 these securities until they recover their value, none of the securities are deemed to be other than temporarily impaired. All residential mortgage-backed securities in the Company’s portfolio at December 31, 2017 and December 31, 2016 were backed by US government sponsored enterprises (“GSEs”). The following is a summary of investment securities by maturity: Available-for-sale Amortized cost Fair value US government agencies Within one year $ 6,323 $ 6,295 One to five years 16,455 16,329 Total 22,778 22,624 Residential mortgage-backed securities Five to ten years 6,815 6,701 After 10 years 63,352 61,995 Total 70,167 68,696 Total $ 92,945 $ 91,320 The table above reflects contractual maturities. Actual results will differ as the loans underlying the mortgage-backed securities may repay sooner than scheduled. This table excludes the 504 Fund mutual fund investment.

Loans Held for Investment and Allowance for Loan Losses	Loans Held for Investment and Allowance for Loan and Lease Losses Loan and Lease Portfolio Segments The following describes the risk characteristics relevant to each of the portfolio segments. Each loan and lease category is assigned a risk grade during the origination and closing process based on criteria described later in this section. Commercial and Industrial Commercial and industrial loans (C&I) receive similar underwriting treatment as commercial real estate loans in that the repayment source is analyzed to determine its ability to meet cash flow coverage requirements as set forth by Bank policies. Repayment of the Bank’s C&I loans generally comes from the generation of cash flow as the result of the borrower’s business operations. This business cycle itself brings a certain level of risk to the portfolio. In some instances, these loans may carry a higher degree of risk due to a variety of reasons – illiquid collateral, specialized equipment, highly depreciable assets, uncollectable accounts receivable, revolving balances, or simply being unsecured. As a result of these characteristics, the SBA guarantee on these loans is an important factor in mitigating risk. Construction and Development Construction and development loans are for the purpose of acquisition and development of land to be improved through the construction of commercial buildings. Such loans are usually paid off through the conversion to permanent financing for the long-term benefit of the borrower’s ongoing operations. At the completion of the project, if the loan is converted to permanent financing or if scheduled loan amortization begins, it is then reclassified to the “Commercial Real Estate” segment. Underwriting of construction and development loans typically includes analysis of not only the borrower’s financial condition and ability to meet the required debt obligations, but also the general market conditions associated with the area and type of project being funded. Commercial Real Estate Commercial real estate loans are extensions of credit secured by owner occupied and non-owner occupied collateral. Underwriting generally involves intensive analysis of the financial strength of the borrower and guarantor, liquidation value of the subject collateral, the associated unguaranteed exposure, and any available secondary sources of repayment, with the greatest emphasis given to a borrower’s capacity to meet cash flow coverage requirements as set forth by Bank policies. Such repayment of owner occupied loans is commonly derived from the successful ongoing operations of the business occupying the property. These typically include small businesses and professional practices. Commercial Land Commercial land loans are extensions of credit secured by farmland. Such loans are often for land improvements related to agricultural endeavors that may include construction of new specialized facilities. These loans are usually repaid through the conversion to permanent financing, or if scheduled loan amortization begins, for the long-term benefit of the borrower’s ongoing operations. Underwriting generally involves intensive analysis of the financial strength of the borrower and guarantor, liquidation value of the subject collateral, the associated unguaranteed exposure, and any available secondary sources of repayment, with the greatest emphasis given to a borrower’s capacity to meet cash flow coverage requirements as set forth by Bank policies. Each of the loan types referenced in the sections above is further segmented into verticals in which the Bank chooses to operate. The Bank chooses to finance businesses operating in specific industries because of certain similarities. The similarities range from historical default and loss characteristics to business operations. However, there are differences that create the necessity to underwrite these loans according to varying criteria and guidelines. When underwriting a loan, the Bank considers numerous factors such as cash flow coverage, the credit scores of the guarantors, revenue growth, practice ownership experience and debt service capacity. Minimum guidelines have been set with regard to these various factors and deviations from those guidelines require compensating strengths when considering a proposed loan. Loans and leases consist of the following: December 31, December 31, Commercial & Industrial Agriculture $ 3,274 $ 1,714 Death Care Management 13,495 9,684 Healthcare 43,301 37,270 Independent Pharmacies 99,920 83,677 Registered Investment Advisors 93,770 68,335 Veterinary Industry 46,387 38,930 Other Industries 184,903 94,836 Total 485,050 334,446 Construction & Development Agriculture 34,188 32,372 Death Care Management 6,119 3,956 Healthcare 49,770 30,467 Independent Pharmacies 1,496 2,013 Registered Investment Advisors 376 294 Veterinary Industry 13,184 11,514 Other Industries 58,120 31,715 Total 163,253 112,331 Commercial Real Estate Agriculture 46,717 5,591 Death Care Management 67,381 52,510 Healthcare 126,631 114,281 Independent Pharmacies 19,028 15,151 Registered Investment Advisors 11,789 11,462 Veterinary Industry 113,932 102,906 Other Industries 134,172 46,245 Total 519,650 348,146 Commercial Land Agriculture 178,897 113,569 Total 178,897 113,569 Total Loans and Leases 1 1,346,850 908,492 Net Deferred Costs 8,545 7,648 Discount on SBA 7(a) and USDA Unguaranteed 2 (11,422 ) (8,574 ) Loans and Leases, Net of Unearned $ 1,343,973 $ 907,566 1 Total loans and leases include $ 99.7 million and $ 37.7 million of U.S. government guaranteed loans as of December 31, 2017 and December 31, 2016 , respectively. 2 The Company measures the carrying value of the retained portion of loans sold at fair value under ASC Subtopic 825-10. The value of these retained loan balances is discounted based on the estimates derived from comparable unguaranteed loan sales. Credit Risk Profile The Bank uses internal loan and lease reviews to assess the performance of individual loans and leases by industry segment. An independent review of the loan and lease portfolio is performed annually by an external firm. The goal of the Bank’s annual review of each borrower’s financial performance is to validate the adequacy of the risk grade assigned. The Bank uses a grading system to rank the quality of each loan and lease. The grade is periodically evaluated and adjusted as performance dictates. Loan and lease grades 1 through 4 are passing grades and grade 5 is special mention. Collectively, grades 6 through 8 represent classified loans and leases in the Bank’s portfolio. The following guidelines govern the assignment of these risk grades: Exceptional (1 Rated): These loans and leases are of the highest quality, with strong, well-documented sources of repayment. Debt service coverage (“DSC”) is over 1.75 X based on historical results. Secondary source of repayment is strong, with a loan to value (“LTV”) of 65% or less if secured solely by commercial real estate (“CRE”). Discounted collateral coverage from all sources should exceed 125% . Guarantors have credit scores above 740 . Quality (2 Rated): These loans and leases are of good quality, with good, well-documented sources of repayment. DSC is over 1.25 X based on historical or pro-forma results. Secondary source of repayment is good, with a LTV of 75% or less if secured solely by CRE. Discounted collateral coverage should exceed 100% . Guarantors have credit scores above 700 . Acceptable (3 rated): These loans and leases are of acceptable quality, with acceptable sources of repayment. DSC of over 1.00 X based on historical or pro-forma results. Companies that do not meet these credit metrics must be evaluated to determine if they should be graded below this level. Acceptable (4 rated): These loans and leases are considered very weak pass. These loans and leases are riskier than a 3-rated credit, but due to various mitigating factors are not considered a Special Mention or worse. The mitigating factors must clearly be identified to offset further downgrade. Examples of loans and leases that may be put in this category include start-up loans and leases and loans and leases with less than 1 :1 cash flow coverage with other sources of repayment. Special mention (5 rated): These loans and leases are considered as emerging problems, with potentially unsatisfactory characteristics. These loans and leases require greater management attention. A loan or lease may be put into this category if the Bank is unable to obtain financial reporting from a company to fully evaluate its position. Substandard (6 rated): Loans and leases graded Substandard are inadequately protected by current sound net worth, paying capacity of the borrower, or pledged collateral. They typically have unsatisfactory characteristics causing more than acceptable levels of risk, and have one or more well-defined weaknesses that could jeopardize the repayment of the debt. Doubtful (7 rated): Loans and leases graded Doubtful have inherent weaknesses that make collection or liquidation in full questionable. Loans and leases graded Doubtful must be placed on non-accrual status. Loss (8 rated): Loss rated loans and leases are considered uncollectible and of such little value that their continuance as an active Bank asset is not warranted. The asset should be charged off, even though partial recovery may be possible in the future.

Nonaccrual Loans and Leases Loans and leases that become 90 days delinquent, or in cases where there is evidence that the borrower’s ability to make the required payments is impaired, are placed in nonaccrual status and interest accrual is discontinued. If interest on nonaccrual loans and leases had been accrued in accordance with the original terms, interest income would have increased by approximately $ 1.1 million , $ 622 thousand and $ 794 thousand for the years ended December 31, 2017 , 2016 , and 2015 , respectively. All nonaccrual loans and leases are included in the held for investment portfolio.

The Company’s methodology for determining the ALLL is based on the requirements of GAAP, the Interagency Policy Statement on the Allowance for Loan and Lease Losses and other regulatory and accounting pronouncements. The ALLL is determined by the sum of three separate components: (i) the impaired loan and lease component, which addresses specific reserves for impaired loans and leases; (ii) the general reserve component, which addresses reserves for pools of homogeneous loans and leases; and (iii) an unallocated reserve component (if any) based on management’s judgment and experience. The loan and lease pools and impaired loans and leases are mutually exclusive; any loan or lease that is impaired is excluded from its homogenous pool for purposes of that pool’s reserve calculation, regardless of the level of impairment. The ALLL policy for pooled loans and leases is governed in accordance with banking regulatory guidance for homogenous pools of non-impaired loans and leases that have similar risk characteristics. The Company follows a consistent and structured approach for assessing the need for reserves within each individual loan and lease pool. Loans and leases are considered impaired when, based on current information and events, it is probable that the creditor 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 that meet the criteria defined below must be reviewed quarterly to determine if they are impaired. • All commercial loans and leases classified substandard or worse. • Any other delinquent loan or lease that is in a nonaccrual status, or any loan or lease that is delinquent more than 89 days and still accruing interest. • Any loan or lease which has been modified such that it meets the definition of a TDR. The Company’s policy for impaired loan accounting subjects all loans and leases to impairment recognition; however, loan and lease relationships with unguaranteed credit exposure of less than $100,000 are generally not evaluated on an individual basis for impairment and instead are evaluated collectively using a methodology based on historical specific reserves on similar sized loans or leases. Any loan or lease not meeting the above criteria and determined to be impaired is subjected to an impairment analysis, which is a calculation of the probable loss on the loan or lease. This portion is the loan’s “impairment,” and is established as a specific reserve against the loan or lease, or charged against the ALLL. Individual specific reserve amounts imply probability of loss and may not be carried in the reserve indefinitely. When the amount of the actual loss becomes reasonably quantifiable, the amount of the loss is charged off against the ALLL, whether or not all liquidation and recovery efforts have been completed. If the total amount of the individual specific reserve that will eventually be charged off cannot yet be sufficiently quantified but some portion of the impairment can be viewed as a confirmed loss, then the confirmed loss portion should be charged off against the ALLL and the individual specific reserve reduced by a corresponding amount. For impaired loans and leases, the reserve amount is calculated on a loan or lease-specific basis. The Company utilizes two methods of analyzing impaired loans and leases not guaranteed by the SBA: • The Fair Market Value of Collateral method utilizes the value at which the collateral could be sold considering the appraised value, appraisal discount rate, prior liens and selling costs. The amount of the reserve is the deficit of the estimated collateral value compared to the loan or lease balance. • The Present Value of Future Cash Flows method takes into account the amount and timing of cash flows and the effective interest rate used to discount the cash flows.

Transfers and Servicing [Abstract]
Servicing Assets	Servicing Assets Loans serviced for others are not included in the accompanying balance sheet. The unpaid principal balances of loans serviced for others requiring recognition of a servicing asset were $ 2.44 billion , $ 2.22 billion and $1.78 billion at December 31, 2017 , 2016 and 2015, respectively. The unpaid principal balance for all loans serviced for others was $2.54 billion , $2.35 billion and $1.94 billion at December 31, 2017, 2016 and 2015, respectively. The following summarizes the activity pertaining to servicing rights: 2017 2016 Balance at beginning of period $ 51,994 $ 44,230 Additions, net 14,028 16,584 Fair value changes: Due to changes in valuation inputs or assumptions (2,722 ) (955 ) Decay due to increases in principal paydowns or runoff (11,002 ) (7,865 ) Balance at end of period $ 52,298 $ 51,994 The fair value of servicing rights was determined using discount rates ranging from 0.00% to 15.40% on December 31, 2017 , and 8.70% to 13.90% on December 31, 2016 . The fair value of servicing rights was determined using prepayment speeds ranging from 0.00% to 11.50% on December 31, 2017 and 2.40% to 9.80% on December 31, 2016 , depending on the stratification of the specific right. Changes to fair value are reported in loan servicing revenue and 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 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. 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.

The 21% tax rate positively impacted 2017 due to the revaluation of the Company’s deferred tax assets and liabilities. As such, the Company recorded a provisional net tax benefit of $18.9 million . On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740, Income Taxes. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. The Company has recorded a provisional amount in the consolidated financial statements and expects the accounting to be completed during the fourth quarter of 2018. The final amount may differ from the provisional amount due to additional analysis, regulatory guidance that may be issued or changes in interpretation. Components of deferred tax assets and liabilities are as follows: 2017 2016 2015 Deferred tax assets: Tax credit carryforwards $ 20,272 $ — $ — Allowance for loan and lease losses 5,806 6,828 2,780 Mark to market on loans held for sale 5,751 — — Stock-based compensation expense 1,872 3,877 — Goodwill and intangibles 1,259 — — Accrued expenses 375 725 505 Other 1,062 1,395 734 Total deferred tax assets 36,397 12,825 4,019 Deferred tax liabilities: Investment in joint venture 16,320 — — Unguaranteed loan discount 6,615 4,644 4,083 Premises and equipment 24,112 7,193 3,952 Deferred loan fees and costs, net 1,139 1,321 892 Other 323 — — Total deferred tax liabilities 48,509 13,158 8,927 Net deferred tax liability $ 12,112 $ 333 $ 4,908 The Company has recorded a deferred tax asset of $ 20.3 million related to tax credit carryforwards which will expire in 2037. The Company does not have any material uncertain tax positions and does not have any interest and penalties recorded in the income statement for the years ended December 31, 2017 , 2016 and 2015 . The Company files a consolidated income tax return in the U.S. federal tax jurisdiction.

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. Financial Instruments Measured at Fair Value The following sections provide a description of the valuation methodologies used for instruments measured at fair value, 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 US government agency securities, mortgage-backed securities, obligations of states and political subdivisions and certain corporate, asset backed 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. Impaired loans : Impairment of a loan is based on the fair value of the collateral of the loan for collateral-dependent loans. Fair value of the loan’s collateral, when the loan is dependent on collateral, is determined by appraisals or independent valuation which is then adjusted for the cost related to liquidation of the collateral. For non-collateral dependent loans, impairment is determined by the present value of expected future cash flows. Impaired loans classified as Level 3 are based on management’s judgment and estimation. 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. 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. When the fair value of the collateral is based on an observable market price or a current appraised value, the Company records the foreclosed asset as nonrecurring Level 2. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value and there is no observable market price, the Company records foreclosed real estate as nonrecurring Level 3. Foreclosed assets classified as Level 3 are based on management’s judgment and estimation. Contingent consideration liability: Contingent consideration associated with the acquisition of Reltco will be adjusted to fair value quarterly until settled. The assumptions used to measure fair value are based on internal metrics that are unobservable and therefore the contingent consideration liability is classified within Level 3 of the valuation hierarchy. Recurring Fair Value The tables below present the recorded amount of assets and liabilities measured at fair value on a recurring basis. December 31, 2017 Total Level 1 Level 2 Level 3 Investment securities available-for-sale US government agencies $ 22,624 $ — $ 22,624 $ — Residential mortgage-backed securities 68,696 — 68,696 — Mutual fund 2,035 — 2,035 — Servicing assets 1 52,298 — — 52,298 Total assets at fair value $ 145,653 $ — $ 93,355 $ 52,298 Contingent consideration liability 2 $ 1,900 $ — $ — $ 1,900 Total liabilities at fair value $ 1,900 $ — $ — $ 1,900 December 31, 2016 Total Level 1 Level 2 Level 3 Investment securities available-for-sale US government agencies $ 17,823 $ — $ 17,823 $ — Residential mortgage-backed securities 51,273 — 51,273 — Mutual fund 1,960 — 1,960 — Servicing assets 1 51,994 — — 51,994 Total assets at fair value $ 123,050 $ — $ 71,056 $ 51,994 1 See Note 6 for a rollforward of recurring Level 3 fair values for servicing assets. 2 See Note 2 for activity related to the recurring Level 3 fair value for the contingent consideration liability and various assumptions used in the fair value measurement. Non-recurring Fair Value The tables below present the recorded amount of assets and liabilities measured at fair value on a non-recurring basis. December 31, 2017 Total Level 1 Level 2 Level 3 Impaired loans $ 34,493 $ — $ — $ 34,493 Foreclosed assets 1,281 — — 1,281 Total assets at fair value $ 35,774 $ — $ — $ 35,774 December 31, 2016 Total Level 1 Level 2 Level 3 Impaired loans $ 27,815 $ — $ — $ 27,815 Foreclosed assets 1,648 — — 1,648 Total assets at fair value $ 29,463 $ — $ — $ 29,463 Level 3 Analysis For Level 3 assets and liabilities measured at fair value on a non-recurring basis as of December 31, 2017 and December 31, 2016 the significant unobservable inputs used in the fair value measurements were as follows: December 31, 2017 Level 3 Assets with Significant Unobservable Inputs Fair Value Valuation Technique Significant Unobservable Inputs Range Impaired Loans $ 34,493 Discounted appraisals Appraisal adjustments (1) Interest rate & repayment term 10% to 25% Foreclosed Assets $ 1,281 Discounted appraisals Appraisal adjustments (1) 10% to 37% December 31, 2016 Level 3 Assets with Significant Unobservable Inputs Fair Value Valuation Technique Significant Unobservable Inputs Range Impaired Loans $ 27,815 Discounted appraisals Appraisal adjustments (1) Interest rate & repayment term 0% to 25% Foreclosed Assets $ 1,648 Discounted appraisals Appraisal adjustments (1) 10% to 35% (1) Appraisals may be adjusted by management for customized discounting criteria, estimated sales costs, and proprietary qualitative adjustments. Estimated Fair Value of Other Financial Instruments GAAP also requires disclosure of fair value information about financial instruments carried at book value on the consolidated balance sheet. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instruments. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the Company. The following methods and assumptions were used by the Company in estimating its fair value disclosures for financial instruments not measured at fair value on the consolidated balance sheets: Cash and due from banks : The carrying amounts reported in the balance sheet for cash and due from banks approximate their fair values. Certificates of deposit with other banks : The fair value of certificates of deposit with other banks is estimated based on discounting cash flows using the rates currently offered for instruments of similar remaining maturities. Loans held for sale: The fair values of loans held for sale are based on quoted market prices, where available, and determined by discounting estimated cash flows using interest rates approximating the Company’s current origination rates for similar loans adjusted to reflect the inherent credit risk. Loans and leases held for investment : For variable-rate loans and leases that reprice frequently and with no significant change in credit risk, fair values are based on carrying amounts. The fair values for other loans and leases are estimated using discounted cash flow analysis, based on interest rates currently being offered for loans and leases with similar terms to borrowers of similar credit quality. Loan and lease fair value estimates include judgments regarding future expected loss experience and risk characteristics. Fair values for impaired loans are estimated using discounted cash flow analysis or underlying collateral values, where applicable. Accrued interest: The carrying amounts of accrued interest approximate fair value. Deposits : The fair values disclosed for demand deposits (e.g., interest and non-interest checking, passbook savings, and certain types of money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). The carrying amounts of variable-rate, fixed-term money market accounts and certificates of deposit approximate their fair values at the reporting date. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits. Short and long term borrowings: The fair values of the Company’s short term borrowings approximate fair value while long term borrowings are estimated using discounted cash flow analyses based on the Company’s current incremental debt rates for similar types of debt arrangements. The carrying amounts and estimated fair values of the Company’s financial instruments are as follows: December 31, 2017 Carrying Amount Quoted Price In Active Markets for Identical Assets/Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Fair Value Financial assets Cash and due from banks $ 295,271 $ 295,271 $ — $ — $ 295,271 Certificates of deposit with other banks 3,000 2,993 — — 2,993 Investment securities, available-for-sale 93,355 — 93,355 — 93,355 Loans held for sale 680,454 — — 706,972 706,972 Loans and leases, net of allowance for loan and lease losses 1,319,783 — — 1,319,615 1,319,615 Servicing assets 52,298 — — 52,298 52,298 Accrued interest receivable 10,160 10,160 — — 10,160 Financial liabilities Deposits 2,260,263 — 2,232,370 — 2,232,370 Accrued interest payable 367 367 — — 367 Long term borrowings 26,564 — — 27,390 27,390 December 31, 2016 Carrying Amount Quoted Price In Active Markets for Identical Assets/Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Fair Value Financial assets Cash and due from banks $ 238,008 $ 238,008 $ — $ — $ 238,008 Certificates of deposit with other banks 7,250 7,236 — — 7,236 Investment securities, available-for-sale 71,056 — 71,056 — 71,056 Loans held for sale 394,278 — — 397,391 397,391 Loans and leases, net of allowance for loan and lease losses 889,357 — — 873,158 873,158 Servicing assets 51,994 — — 51,994 51,994 Accrued interest receivable 7,520 7,520 — — 7,520 Financial liabilities Deposits 1,485,076 — 1,469,173 — 1,469,173 Accrued interest payable 319 319 — — 319 Long term borrowings 27,843 — — 29,559 29,559

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. 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: December 31, December 31, Commitments to extend credit $ 1,701,137 $ 1,342,271 Standby letters of credit 2,298 343 Solar purchase commitments 106,921 — Airplane purchase agreement commitments 25,450 21,500 Total unfunded off-balance sheet credit risk $ 1,835,806 $ 1,364,114 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. Solar purchase commitments are to purchase solar assets to fulfill leasing obligations. 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 December 31, 2017 and 2016 , the Company had commitments for on-balance sheet instruments in the amount of $ 3.5 million and $ 4.9 million , respectively. Concentrations of Credit Risk Although the Company is not subject to any geographic concentrations, a substantial amount of the Company’s loans 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 exposure exceeds $ 7.5 million , except for nine relationships that have a retained unguaranteed exposure of $ 101.7 million of which $ 70.0 million of the unguaranteed exposure has been disbursed. Additionally, the Company has future minimum lease payments due under non-cancelable operating leases totaling $ 61.0 million , of which $ 43.4 million is due from three relationships. The Company from time-to-time may have cash and cash equivalents on deposit with financial institutions that exceed federally-insured limits.

The plan covers substantially all employees who are at least 21 years of age and have completed one month of service. Participants may contribute a percentage of compensation, subject to a maximum allowed under the Code. In addition, the Company makes certain matching contributions and may make additional contributions at the discretion of the board of directors. Company expense relating to the plan for the years ended December 31, 2017 , 2016 , and 2015 amounted to $ 2.5 million , $ 2.0 million and $ 1.4 million , respectively. Flexible Benefits Plan The Company maintains a Flexible Benefits Plan which covers substantially all employees. Participants may set aside pre-tax dollars to provide for future expenses such as dependent care. Employee Stock Purchase Plan The Company adopted an Employee Stock Purchase Plan (2014 ESPP) on October 8, 2014. On May 24, 2016, the 2014 ESPP was amended and the Amended and Restated Employee Stock Purchase Plan became effective (ESPP), within the meaning of Section 423 of the Internal Revenue Code of 1986, as amended. Under this plan, eligible employees are able to purchase available shares with post-tax dollars as of the grant date. In order for employees to be eligible to participate in this plan they must be employed or on an authorized leave of absence from the Company or any subsidiary immediately prior to the grant date. ESPP stock purchases cannot exceed $ 25 thousand in fair market value per employee per calendar year. Options to purchase shares under the ESPP are granted at a 15% discount to fair market value. Expense recognized in relation to the ESPP was $ 79 thousand in fiscal year 2017. There were no ESPP purchases during 2015 or 2016. Stock Option Plans In 2008, the Company adopted both an Incentive Stock Option (ISO) Plan and a Non-Qualified Stock Option (NQSO) Plan. Options granted under both plans expire no more than ten years from date of grant. Exercise prices under both plans 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 three to seven year periods from the date of the grant for both 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 (the "Plan") was amended and restated to authorize awards covering a maximum of 7,000,000 common voting shares and has an expiration date of March 20, 2025. Options or restricted shares granted under the the Plan expire no more than 10 years from 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 or restricted shares vest over a minimum of three years from the date of the grant. Compensation cost relating to share-based payment transactions are recognized in the financial statements with measurement based upon the fair value of the equity or liability instruments issued. For the years ended December 31, 2017 , 2016 , and 2015 the Company recognized $ 1.7 million , $ 2.3 million , and $ 1.3 million in compensation expense for stock options, respectively. Stock option activity under the Plan during the year ended December 31, 2017 is summarized below. Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value Outstanding at December 31, 2016 3,478,208 $ 11.51 Exercised 109,010 9.41 Forfeited 310,739 14.37 Granted — — Outstanding at December 31, 2017 3,058,459 $ 11.30 7.04 years $ 38,398,463 Exercisable at December 31, 2017 693,460 $ 10.43 6.83 years $ 9,308,406 The following is a summary of non-vested stock option activity for the Company for the years ended December 31, 2017 , 2016 , and 2015 . Shares Weighted Average Grant Date Fair Value Non-vested at December 31, 2014 1,704,230 $ 1.18 Granted 2,088,316 6.81 Vested 173,180 0.88 Forfeited 225,925 2.66 Non-vested at December 31, 2015 3,393,441 4.56 Granted 169,987 6.58 Vested 372,515 4.41 Forfeited 174,813 3.06 Non-vested at December 31, 2016 3,016,100 4.78 Granted — — Vested 340,362 4.36 Forfeited 310,739 6.25 Non-vested at December 31, 2017 2,364,999 $ 4.65 The total intrinsic value of options exercised during the years ended December 31, 2017 , 2016 , and 2015 was $ 1.5 million , $ 590 thousand , and $ 445 thousand , respectively. At December 31, 2017 , unrecognized compensation costs relating to stock options amounted to $ 8.8 million which will be recognized over a weighted average period of 2.70 years. The weighted average fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model. The expected volatility is based on historical volatility. The risk-free interest rates for periods within the contractual life of the awards are based on the U.S. Treasury yield curve in effect at the time of the grant. The expected life is based on historical exercise experience. The dividend yield assumption is based on the Company’s history and expectation of dividend payouts. There were no options granted in 2017. Weighted average assumptions used for options granted during the the years ended December 31, 2016 and 2015 were as follows: 2016 2015 Risk free rate 1.56 % 1.95 % Dividend yield 0.05 % 1.00 % Volatility 44.20 % 43.53 % Average life (in years) 7 4-7 Restricted Stock Plan In 2010, the Company adopted a Restricted Stock Plan. Under this plan, a total of 1,350,000 shares of Common Stock were available for issuance to eligible employees. Restricted stock grants vest in equal installments over a two to four year period from the date of the grant. During 2015, 65,122 restricted shares at a weighted average grant date fair value of $16.10 per share were granted under the 2015 Omnibus Stock Incentive Plan which replaced the previously existing Restricted Stock Plan. During 2016, 2,962,486 restricted stock units were granted to eligible employees and outside directors at a weighted average grant date fair value of $9.76 per share, of which 2,872,000 restricted stock units had market price conditions or non-market-related performance criteria restrictions. During 2017, 340,318 restricted stock units were granted to eligible employees and outside directors at a weighted average grant date fair value of $ 17.00 per share, of which 233,791 restricted stock units had market price conditions or non-market-related performances criteria restrictions. The fair value of each restricted stock unit is based on the market value of the Company’s stock on the date of the grant. Restricted stock awards are authorized in the form of restricted stock awards or units ("RSUs") and restricted stock awards or units with a market price condition ("Market RSUs"). 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 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 ranging from $34.00 to $ 38.00 per share for at least twenty (20) consecutive trading days at any time prior to the expiration date of the grants. 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. The following is a summary of non-vested RSU stock activity for the Company for the year ended December 31, 2017 . Shares Weighted Average Grant Date Fair Value Non-vested at December 31, 2016 134,969 $ 14.96 Granted 106,527 23.71 Vested 39,002 15.45 Forfeited 20,680 14.55 Non-vested at December 31, 2017 181,814 $ 20.03 During 2016 and 2015, the Company granted 597,986 and 65,122 RSUs, respectively. The weighted average grant date fair value for RSUs granted in 2016 and 2015 were $ 15.61 and $ 16.10 , respectively. For the years ended December 31, 2017 , 2016 , and 2015 the Company recognized $ 741 thousand , $ 8.5 million , and $ 148 thousand in compensation expense for RSUs, respectively. At December 31, 2017 , unrecognized compensation costs relating to RSUs amounted to $ 3.2 million which will be recognized over a weighted average period of 4.54 years. The following is a summary of non-vested Market RSU stock activity for the Company for the year ended December 31, 2017 . Shares Weighted Average Grant Date Fair Value Non-vested at December 31, 2016 2,364,500 $ 8.28 Granted 233,791 13.94 Vested — — Forfeited 65,483 9.17 Non-vested at December 31, 2017 2,532,808 $ 8.78 During 2016, the Company granted 2,364,500 Market RSUs with a weighted average grant date fair value of $ 8.28 . The compensation expense for Market RSUs is measured based on their grant date fair value as calculated using the Monte Carlo Simulation and is recognized on a straight-line basis over the average vesting period. The Monte Carlo Simulation used 100,000 simulation paths to assess the expected date of achieving the market price criteria. Related to the 100,733 Market RSUs granted on January 31, 2017 and the 3,058 Market RSUs granted on May 8, 2017, the share price simulation was based on the Cox, Ross & Rubinstein option pricing methodology for a period of 7.0 years. The implied term of the restricted stock was 4.1 years. The Monte Carlo Simulation used various assumptions that included a risk free rate of return of 2.28% , expected volatility of 30.00% and a dividend yield of 0.39% . Related to the 130,000 Market RSUs granted on August 7, 2017, the share price simulation was based on the Cox, Ross & Rubinstein option pricing methodology for a period of 7.0 years. The implied term of the restricted stock was 3.9 years. The Monte Carlo Simulation used various assumptions that included a risk free rate of return of 2.07% , expected volatility of 30.00% and a dividend yield of 0.33% . For the year ended December 31, 2017 and 2016 , the Company recognized $ 5.0 million and $ 1.2 million , respectively, in compensation expense for Market RSUs. At December 31, 2017 , unrecognized compensation costs relating to Market RSUs amounted to $ 16.2 million which will be recognized over a weighted average period of 3.01 years. Employee/Outside Director Bonus Plan In 2014, the Company adopted a Bonus Plan whereby eligible employees and outside directors were qualified to receive quarterly and annual bonus payments based on each individual’s base pay/annual director fees and the profitability of the Company.

Banking and Thrift [Abstract]
Regulatory Matters	Regulatory Matters Dividends The Bank, as a North Carolina banking corporation, may pay dividends to shareholders provided the bank does not make distributions that reduce its capital below its applicable required capital, pursuant to North Carolina General Statutes Section 53C-4-7. However, regulatory authorities may limit payment of dividends by any bank when it is determined that such a limitation is in the public interest and is necessary to ensure financial soundness of the bank. Capital Requirements The Company (on a consolidated basis) and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s and Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting principles. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Prompt corrective action provisions are not applicable to bank holding companies. The Basel III Capital Rules, a comprehensive capital framework for U.S. banking organizations, became effective for the Company and Bank on January 1, 2015 (subject to a phase-in period for certain provisions). Quantitative measures established by the Basel III Capital Rules to ensure capital adequacy require the maintenance of minimum amounts and ratios (set forth in the table below) of Common Equity Tier 1 capital, Tier 1 capital and Total capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital to adjusted quarterly average assets (as defined). Management believes, as of December 31, 2017 and 2016 that the Company and the Bank meet all capital adequacy requirements to which they are subject. When fully phased in on January 1, 2019, the Basel III Capital Rules will require the Company and Bank to maintain (i) a minimum ratio of Common Equity Tier 1 capital to risk-weighted assets of at least 4.5%, plus a 2.5% "capital conservation buffer" (which is added to the 4.5% Common Equity Tier 1 capital ratio as that buffer is phased in, effectively resulting in a minimum ratio of Common Equity Tier 1 capital to risk-weighted assets of at least 7.0% upon full implementation), (ii) a minimum ratio of Tier 1 capital to risk-weighted assets of at least 6.0%, plus the capital conservation buffer (which is added to the 6.0% Tier 1 capital ratio as that buffer is phased in, effectively resulting in a minimum Tier 1 capital ratio of 8.5% upon full implementation), (iii) a minimum ratio of Total capital (that is, Tier 1 plus Tier 2) to risk-weighted assets of at least 8.0%, plus the capital conservation buffer (which is added to the 8.0% total capital ratio as that buffer is phased in, effectively resulting in a minimum total capital ratio of 10.5% upon full implementation) and (iv) a minimum leverage ratio of 4.0%, calculated as the ratio of Tier 1 capital to average quarterly assets. The implementation of the capital conservation buffer began on January 1, 2016 at the 0.625% level and will be phased in over a three-year period (increasing by that amount on each subsequent January 1, until it reaches 2.5% on January 1, 2019). Banking institutions with a ratio of Common Equity Tier 1 capital to risk-weighted assets below the effective minimum (4.5% plus the capital conservation buffer) will face constraints on dividends, equity repurchases and compensation based on the amount of the shortfall. As of December 31, 2017 , the most recent notification from the Federal Deposit Insurance Corporation categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, an institution must maintain minimum common equity Tier 1 risk-based, total risk-based, Tier 1 risk-based and Tier 1 leverage ratios as set forth in the following tables. There are no conditions or events since the notification that management believes have changed the Bank’s category. Capital amounts and ratios as of December 31, 2017 and 2016 , are presented in the table below.

Organization and Summary of Significant Accounting Policies (Policies)	12 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Dollar amounts in all tables in the Notes to Consolidated Financial Statements have been presented in thousands, except percentage, time period, stock option, share and per share data. The accounting and reporting policies of the Company and the Bank follow United States generally accepted accounting principles and general practices within the financial services industry. The following is a description of the significant accounting and reporting policies the Company follows in preparing and presenting its consolidated financial statements.
Consolidation Policy	The consolidated financial statements include the financial statements of the Company and wholly-owned subsidiaries of Live Oak Banking Company, Live Oak Number One, GLS, 504FA, Grove, Canapi, Live Oak Clean Energy Financing and Reltco. All significant intercompany balances and transactions have been eliminated in consolidation. In addition, the Company evaluates its relationships with other entities to identify whether they are variable interest entities and to assess whether it is the primary beneficiary of such entities. If the determination is made that the Company is the primary beneficiary, then that entity is included in the consolidated financial statements. If an entity is not a variable interest entity, the Company also evaluates arrangements in which there is a general partner or managing member to determine whether consolidation is appropriate. Unconsolidated investments where we have the ability to exercise significant influence over the operating and financial policies of the respective investee are accounted for using the equity method of accounting; those that are not consolidated or accounted for using the equity method of accounting are accounted for under cost or fair value accounting. For these investments accounted for under the equity method, the Company records its investment in non-consolidated affiliates and the portion of income or loss in equity in income of non-consolidated affiliates. The Company periodically evaluates these investments for impairment.
Equity Method Investments	Unconsolidated investments where we have the ability to exercise significant influence over the operating and financial policies of the respective investee are accounted for using the equity method of accounting; those that are not consolidated or accounted for using the equity method of accounting are accounted for under cost or fair value accounting. For these investments accounted for under the equity method, the Company records its investment in non-consolidated affiliates and the portion of income or loss in equity in income of non-consolidated affiliates. The Company periodically evaluates these investments for impairment.
Variable Interest Entity	Variable interests are defined as contractual ownership or other interests in an entity that change with fluctuations in an entity's net asset value. The primary beneficiary consolidates the variable interest entity ("VIE"). The primary beneficiary is defined as the enterprise that has both the power to direct the activities of the VIE that most significantly impact the entity's economic performance and the obligation to absorb losses or the right to receive benefits that could be significant to the VIE. The Company has a limited interest in a partnership that owns and operates a solar renewable energy project which is accounted for as an equity method investment. Over the course of the investment, the Company will receive federal and state tax credits, tax-related benefits, and excess cash available for distribution, if any. The Company may be called to sell its interest in the limited partnerships through a call option once all investment tax credits have been recognized. This entity meets the criteria of a VIE; however, the Company is not the primary beneficiary of the entities, as the general partner has both the power to direct the activities that most significantly impact the economic performance of the entities and the obligation to absorb losses or the right to receive benefits that could be significant to the entity. While the partnership agreement allows the Company to remove the general partner, this right is not deemed to be substantive as the general partner can only be removed for cause. The Company’s investments in the unconsolidated VIE is carried in other assets on the consolidated balance sheet and the Company’s unfunded capital and other commitments related to the unconsolidated VIE is carried in other liabilities on the consolidated balance sheet. The Company’s maximum exposure to loss from this unconsolidated VIE includes the investment recorded on the Company’s consolidated balance sheet, net of unfunded capital commitments and any impairment recognized, and previously recorded tax credits which remain subject to recapture by taxing authorities based on compliance features required to be met at the project level. While the Company believes the potential for losses from this investment is remote, the maximum exposure was determined by assuming a scenario where related tax credits were recaptured.
Business Combinations	Business combinations are accounted for by applying the acquisition method in accordance with Accounting Standards Codification (ASC) 805, Business Combinations. Under the acquisition method, identifiable assets acquired and liabilities assumed, and any non-controlling interest in the acquiree at the acquisition date are measured at their fair values as of that date, and are recognized separately from goodwill. Results of operations of the acquired entities are included in the consolidated statements of comprehensive income from the date of acquisition. Any measurement-period adjustments are recorded in the period the adjustment is identified.
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 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.
Use of Estimates	In preparing financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”), management is required to make estimates and assumptions that affect reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan and lease losses, valuations of servicing assets and income taxes.
Cash and Cash Equivalents	For the purpose of presentation in the statement of cash flows, cash and cash equivalents are defined as those amounts included in the balance sheet caption “cash and due from banks.” Cash and cash equivalents have initial maturity of three months or less. Certificates of deposit with other banks have maturities ranging from March 2018 through December 2018 and bear interest at rates ranging from 0.15% to 1.90% . None of the certificates of deposit had maturities of 12 months or less at the time of origination. All investments in certificates of deposit are with FDIC insured financial institutions and none exceed the maximum insurable amount of $250 thousand.
Investments	Securities Certain debt securities that management has the positive intent and ability to hold to maturity are classified as “held-to-maturity” and recorded at amortized cost. Trading securities are recorded at fair value with changes in fair value included in earnings. Securities not classified as held-to-maturity or trading, are classified as “available-for-sale” and recorded at fair value. Unrealized gains and losses for available-for-sale investment securities are excluded from earnings and reported in other comprehensive income. The Company’s entire portfolio for the periods presented is available-for-sale. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Other The Company accounts for other investments either under the equity or cost method. Investments through which there is significant influence but not control over the investee are accounted for under the equity method. Investments through which the Company is not able to exercise significant influence over the investee are accounted for under the cost method. Other investments are generally non-marketable equity investments and are included in the other assets line on the consolidated balance sheet. Impairment At each reporting date, the Company evaluates each investment in a loss position for other than temporary impairment (“OTTI”). The Company evaluates declines in market value below cost for debt securities by assessing the likelihood of selling the security prior to recovering its cost basis. If the Company intends to sell the debt security or it is more-likely-than-not that the Company will be required to sell the debt security prior to recovering its cost basis, the Company will write down the security to fair value with the full charge recorded in earnings. If the Company does not intend to sell the debt security and it is not more-likely-than-not that the Company will be required to sell the debt security prior to recovery, the security will not be considered other-than-temporarily impaired unless there are credit losses associated with the security. In that case: (1) where credit losses exist, the portion of the impairment related to those credit losses should be recognized in earnings; (2) any remaining difference between the fair value and the cost basis should be recognized as part of other comprehensive income. For equity securities, any OTTI is recognized with the full charge recorded in earnings. To determine whether an impairment of equity securities is OTTI, the Company considers whether it has the ability and intent to hold the investment until there is a market price recovery and considers whether evidence indicating the cost of the investment is recoverable outweighs evidence to the contrary. In determining whether OTTI exists, management considers many factors, including (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. Gains and losses on the sales of securities are recorded on the trade date and are determined using the specific identification method.
Loans Held For Sale	Management designates loans as held for sale ("HFS") based on its intent to sell guaranteed portions in the SBA and USDA Secondary Market and unguaranteed portions to participant banks and credit unions. Salability requirements of the guaranteed portion include, but are not limited to, full disbursement of the loan commitment amount. Loans originated and intended for sale are carried at the lower of cost or estimated fair value on a loan-by-loan basis. The cost basis of loans held for sale includes the deferral of loan origination fees and costs. Deferred fees and costs are accreted and amortized for loans classified held for sale until the sale occurs. At loan settlement, the pro-rata portion, based on the percent of the total loan sold, of the remaining deferred fees and costs are recognized as an adjustment to the gain on sale. As part of our management of the loans held in our portfolio, we will occasionally transfer loans from held for investment to held for sale. Upon transfer, any associated allowance for loan and lease loss is released and the carrying value of the loans is adjusted to the estimated fair value. The loans are subsequently accounted for at the lower of cost or fair value, with valuation changes recorded in other noninterest income. Gains or losses on the sale of these loans are also recorded in noninterest income. In certain circumstances, loans designated as held for sale may later be transferred back to the loan and lease portfolio based upon our intent and ability to hold the loans for the foreseeable future. The Company transfers these loans to loans and leases held for investment at the lower of cost or fair value and establishes a related allowance for loan and lease loss. In accordance with SBA regulation, the Bank is required to retain 10% of the principal balance of any SBA 7(a) loan comprised of unguaranteed dollars. With written consent from the SBA, the Bank may sell down to a 5% exposure comprised of unguaranteed dollars. During 2012, the SBA approved the Bank to sell to the 5% retention level participating interests of the unguaranteed portion of loans originated on or before June 30, 2012 that had been fully funded for a period of eighteen months. This approval expired on June 30, 2014. Historically, loans held for sale consisted only of guaranteed loan balances and the unguaranteed portion up to the SBA retention minimums discussed above. A negative change in the credit quality of a loan resulted in the loan classification changing from held for sale to held for investment. Beginning in June 2016, loans held for sale consist of guaranteed loan balances. The gain on sale recognized in income is the sum of the premium on the guaranteed loan and the fair value of the servicing assets recognized, less the discount recorded on the unguaranteed portion of the loan retained.
Loans Held for Investment	Loans and leases receivable that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are classified as held for investment ("HFI") and reported at their outstanding principal amount adjusted for any charge-offs, the allowance for loan and lease losses, and any deferred fees or costs on originated loans and leases and unamortized premium or discount on purchased loans. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method. Discounts and premiums on any purchased loans are amortized to income using the interest method over the remaining period to contractual maturity, adjusted for anticipated prepayments. Historically, loans and leases designated as held for investment, included loans and leases identified as more beneficial to hold for the long term as well as the required retention amount defined by the SBA comprised of unguaranteed dollars and loans and leases designated as troubled debt restructurings, nonaccrual, and risk grade at a 5 or worse as defined by internal risk rating metrics. Beginning June 2016, loans and leases held for investment consist of unguaranteed loan and lease balances and guaranteed and unguaranteed loans and leases designated as troubled debt restructurings, nonaccrual, non-marketable, and risk grade 5 or worse. During the second quarter of 2016, the Bank transferred $318.8 million in unguaranteed loans from the HFS category to the HFI category to better reflect intentions of the Company. Interest income on loans and leases is recognized as earned on a daily accrual basis. The accrual of interest on loans and leases is discontinued when principal or interest is past due 90 days or the loan or lease is determined to be impaired. Impaired loans and leases, or portions thereof, are charged off when deemed uncollectible.
Allowance for Loan Losses	The allowance for loan and lease losses is established as losses are estimated to have occurred through a provision for loan and lease losses charged to earnings. Loan or lease losses are charged against the allowance when management believes the un-collectibility of a loan or lease balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan and lease losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectibility of the loans or leases in light of historical experience, the nature and volume of the loan and lease portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. A loan or lease is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan or lease agreement. Factors considered by management in determining impairment include payment status and other circumstances impacting the probability of collecting scheduled principal and interest payments when due. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan or lease and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a credit-by-credit basis by either the present value of expected future cash flows discounted at the loan or lease's effective interest rate, the loan or lease’s obtainable market price, or the fair value of the collateral if the loan or lease is collateral dependent, except for large groups of smaller balance homogeneous loans or leases which are collectively evaluated for impairment. Smaller balance loan or lease relationships collectively evaluated for impairment are generally comprised of credits with unguaranteed exposure of less than $100,000 using a methodology based on historical specific reserves on similar sized loans or leases. Loans or leases classified as troubled debt restructured (“TDR”) are considered impaired. Loans or leases that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. 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 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. The Company measures the impairment loss of a TDR using the methodology for individually impaired loans or leases. Interest is accrued and credited to income based on the principal amount outstanding. The accrual of interest on impaired loans or leases is discontinued when, in management’s opinion, the borrower may be unable to meet payments as they become due or when the loan or lease becomes ninety days past due. Past due status of loans and leases is determined based on contractual terms. When interest accrual is discontinued, all unpaid accrued interest for the current year is reversed. Interest income is subsequently recognized on the cash-basis or cost-recovery method, as appropriate. Cash payments of interest on nonaccrual loans or leases will be applied to the principal balance of the loan or lease. When facts and circumstances indicate the borrower has regained the ability to meet the required payments, the loan or lease is returned to accrual status. Interest accruals are resumed on nonaccrual loans or leases only when it is brought current with respect to interest and principal and when, in the judgment of management, the loans or leases are estimated to be fully collectible as to all principal and interest. Management’s judgment is based on an assessment of the borrower’s financial condition and a recent history of payment performance. The Company identifies all impaired loans and leases, including those individually and collectively evaluated for impairment, for impairment disclosures. Upon transfer from held for sale classification, loans and leases held for investment become subject to the allowance for loan and lease loss review process. As a result of this process, the above mentioned $318.8 million loan reclassification resulted in a $4.0 million increase in the provision for loan and lease losses during the second quarter of 2016. During the second quarter of 2016, the Company also implemented enhancements to the methodology for estimating the allowance for loan and lease losses, including refinements to the measurement of qualitative factors in the estimation process. Management believes these enhancements will improve the precision of the process for estimating the allowance, but did not fundamentally change the Company's approach.
Foreclosed Assets	Real estate properties acquired through, or in lieu of, loan foreclosure are to be sold and are initially recorded at the lower of carrying amount or fair value less anticipated cost to sell at the date of foreclosure, establishing a new cost basis. Any write down at the time of transfer to foreclosed assets is charged to the allowance for loan and lease losses. After foreclosure, valuations are periodically performed by management, and the real estate is carried at the lower of carrying amount or fair value, less cost to sell. Subsequent write downs are charged to other loan origination and maintenance expense. Costs relating to improvement of the property are capitalized while holding costs of the property are charged to other loan origination and maintenance expense in the period incurred.
Premises and Equipment	All premises and equipment, excluding land, are carried at cost, less accumulated depreciation. Land is carried at cost. Additions and major replacements or improvements which extend useful lives of property or equipment are capitalized. Maintenance, repairs, and minor improvements are expensed as incurred. Upon retirement or other disposition of the assets, the cost and related depreciation are removed and any resulting gain or loss is reflected in income. Leasehold improvements are amortized over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. Depreciation is computed by the straight-line method over the following estimated useful lives: Years Buildings 39 Transportation 5-10 Land Improvements 7-15 Furniture and equipment 5-10 Computers and software 3-5
Servicing Assets	All sales of loans are executed on a servicing retained basis. The standard SBA loan sale agreement is structured to provide the Company with a “servicing spread” paid from a portion of the interest cash flow of the loan. SBA regulations require the Bank to retain a portion of the cash flow from the interest payments received for a sold loan. The SBA retention requirement is at least 100 basis points in servicing spread while the Company's standard USDA loan sale agreement specifies a servicing spread of 40 basis points. The portion of the servicing spread that exceeds adequate compensation for the servicing function is recognized as a servicing asset. Industry practice recognizes adequate compensation for servicing SBA and USDA loans as 40 basis points. The fair value of the servicing asset is measured at the discounted present value of the excess servicing spread over the expected life of the related loan using appropriate discount rates and assumptions based on industry statistics for prepayment speeds. Servicing assets are recognized as separate assets when rights are acquired through purchase or through sale of financial assets and are carried at fair value. Generally, purchased servicing rights are capitalized at the cost to acquire the rights. For sales of loans, a portion of the cost of originating the loan is allocated to the servicing right based on fair value. Fair value is based on market prices for comparable servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as adequate compensation for servicing, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. Capitalized servicing rights are carried at fair value as of the reporting date. Changes to fair value are reported in loan servicing asset revaluation. Servicing fee income is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. The Company’s investment in a loan is allocated between the retained portion of the loan, the servicing asset, and the sold portion of the loan on the date the loan is sold. When only a portion of a loan is sold, GAAP requires the Company to reallocate the carrying basis between the portion of the loan sold and the portion of the loan retained based on the relative fair value of the respective portions as of the date of sale. The maximum gain on sale that can be recognized is the difference between the fair value of the guaranteed portion sold and the reallocated basis of the portion of the loan sold. The Company measures the fair value of the guaranteed portion of the loan by the cash premium at which the sale was consummated. The limitation on the maximum gain allowed to be recognized results in a discount recorded on the unguaranteed dollars retained. The carrying value of the retained portion of the loan is discounted based in part on the estimates derived from the Company’s comparable nonguaranteed loan sales.
Derivatives Financial Instruments	During the fourth quarter of 2016, the Company began using exchange-traded interest rate futures contracts to manage interest rate risk that may impact expected gains arising from future secondary market loan sales. Upon entering into a futures contract, the Company is required to pledge to the counterparty an amount of cash equal to a certain percentage of the contract amount, also known as an initial margin deposit. Subsequent payments, known as variation margin, are made or received by the Company each day to settle the daily fluctuations in the fair value of the underlying contract. Investments in these derivative contracts are subject to risks that can result in a loss of all or part of an investment. Credit risk is considered low because the counterparties are futures exchanges. The Company has not designated any derivative as a hedging instrument under applicable accounting guidance. Changes in fair value of the derivative contracts is recorded as a component of "net gains on sales of loans" on the consolidated statement of income. The Company recognized a loss of $117 thousand and a gain of $31 thousand on the derivative contracts for the years ended December 31, 2017 and 2016, respectively. The total notional amount of derivative contracts outstanding was $ 29.9 million and $8.0 million as of December 31, 2017 and 2016, respectively. The fair value of the derivative contracts on the balance sheet date is zero due to the daily cash settlement of contracts.
Advertising Expense	Marketing costs are recognized in the month the event or advertisement takes place. These costs are included in advertising and marketing expense as presented in the consolidated statements of income.
Income Taxes	Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities (excluding deferred tax assets and liabilities related to business combinations or components of other comprehensive income). Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. The effect of a change in tax rates on deferred assets and liabilities is recognized in income taxes during the period that includes the enactment date. A valuation allowance, if needed, reduces deferred tax assets to the expected amount more likely than not to be realized. Realization of deferred tax assets is dependent upon the level of historical income, prudent and feasible tax planning strategies, reversals of deferred tax liabilities and estimates of future taxable income. The Company uses the flow-through method of accounting on investments that generate investment tax credits. Under this method, investment tax credits are recognized as a reduction to income tax expense immediately in the period that the credit is generated, to the extent permitted by tax law. In accounting for any temporary difference that arise, the Company has elected the income statement method whereby deferred taxes are adjusted through income tax expense. The Company evaluates uncertain tax positions at the end of each reporting period. The Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefit recognized in the financial statements from any such position is measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. Any interest and/or penalties related to income taxes are reported as a component of income tax expense.
Comprehensive Income	Annual comprehensive income reflects the change in the Company’s equity during the year arising from transactions and events other than investment by and distributions to shareholders. The only components of other comprehensive income consist of realized and unrealized gains and losses related to investment securities.
Stock Compensation Plans	The Company recognizes compensation cost relating to share-based payment transactions in the consolidated financial statements in accordance with GAAP. The cost is measured based on the fair value of the equity or liability instruments issued. The expense measures the cost of employee services received in exchange for stock options and restricted stock based on the grant-date fair value of the award, and recognizes the cost over the vesting period as indicated in the option agreement.
Fair Value of Financial Instruments	GAAP defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company determines the fair values of its financial instruments based on the fair value hierarchy established per GAAP which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Investment securities available-for-sale and servicing assets are recorded at fair value on a recurring basis. Loans held for sale, certain impaired loans and foreclosed assets are carried at fair value on a non-recurring basis.
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.
Reclassifications and Corrections	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.
Recent Accounting Pronouncements	The following is a summary of recent authoritative pronouncements that could impact the accounting, reporting, and/or disclosure of financial information by the Company. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”). This standard is intended to clarify the principles for recognizing revenue and to develop a common revenue standard for GAAP. The Company's revenue is comprised of loan servicing revenue, net gains on sales of loans and net interest income on financial assets and financial liabilities, all of which are explicitly excluded from the scope of ASU 2014-09, and non-interest income. The Company's revenue streams included in non-interest income that are within the scope of the guidance are primarily related to sales of foreclosed assets, construction supervision fees, title insurance income and trust fiduciary fees. The Company adopted the standard in the first quarter of 2018 with no effect on the consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The FASB issued this ASU to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet by lessees for those leases classified as operating leases under current GAAP and disclosing key information about leasing arrangements. The amendments in this ASU are effective for the Company on January 1, 2019. The impact of this standard will depend on the Company's lease portfolio at the time of the adoption and the Company is currently assessing the effect that the adoption of this standard will have on the consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, “Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). ASU 2016-09 simplifies the accounting for share-based payment transactions for items including income tax consequences, classification of awards as equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 was effective and adopted by the Company on January 1, 2017. Starting in the first quarter of 2017, stock-based compensation excess tax benefits or deficiencies are reflected in the Consolidated Statements of Income as a component of the income tax expense, where as they previously were recognized in equity. Additionally, the Consolidated Statements of Cash Flows now present excess tax benefits as an operating activity while any cash paid in lieu of shares for tax-withholding being classified as a financing activity. There were no excess tax benefits in the prior period presented for reclassification. Finally, the Company will continue to incorporate actual forfeitures as they occur in the accrual of compensation expense. As a result of the adoption of ASU 2016-09, the Consolidated Statement of Cash Flows for the year ended December 31, 2017 was impacted as follows: a $ 1.0 million increase to net cash provided by operating activities and a $4.9 million increase to net cash used in financing activities. The adoption of ASU 2016-09 further resulted in a $ 0.03 increase in basic and diluted EPS for the year ended December 31, 2017. See Note 10 for information regarding the additional impact on our consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, “Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). This new guidance replaces the incurred loss impairment methodology in current standards with an expected credit loss methodology 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. ASU 2016-13 will be effective for the Company on January 1, 2020. The Company is currently evaluating the potential impact of ASU 2016-13 on the consolidated financial statements. In that regard, a cross-functional working group has been formed, under the direction of the Company's Chief Financial Officer and Chief Credit Officer. The working group is comprised of individuals from various functional areas including credit, risk management, finance and information technology, among others. The Company is currently developing an implementation plan to include assessment of processes, portfolio segmentation, model development, system requirements and the identification of data and resource needs, among other things. The Company has also selected a third-party vendor solution to assist in the application of the ASU 2016-13. While the Company is currently unable to reasonably estimate the impact of adopting ASU 2016-13, the impact of adoption is expected to be significantly influenced by the composition, characteristics and quality of loan and securities portfolios as well as the prevailing economic conditions and forecasts as of the adoption date. In January 2017, the FASB issued ASU No. 2017-01, “Business Combinations (Topic 805) - Clarifying the Definition of a Business” (“ASU 2017-01”). ASU 2017-01 clarifies the definition and provides a more robust framework to use in determining when a set of assets and activities constitutes a business. ASU 2017-01 is intended to provide guidance when evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. ASU 2017-01 will be effective for the Company on January 1, 2018. The Company does not expect this amendment to have a material effect on its consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”). This ASU eliminates Step 2 from the goodwill impairment test. Under the new guidance, entities should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. Additionally, this ASU eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. The amendments in this ASU are effective for the Company on January 1, 2020, with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company elected to early adopt ASU 2017-04 in the fourth quarter of 2017. Refer to Note 2. Title Insurance Business for information on this adoption. In February 2017, the FASB issued ASU No. 2017-05, “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) - Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets” (“ASU 2017-05”). ASU 2017-05 clarifies the scope of Subtopic 610-20 and adds guidance on nonfinancial asset derecognition as well as the accounting for partial sales of nonfinancial assets. The amendments conform the derecognition guidance on nonfinancial assets with the model for transactions in the new revenue standard. ASU 2017-05 will be effective for the Company on January 1, 2018 and is not expected to have a significant impact on its consolidated financial statements. In May 2017, the FASB issued ASU No. 2017-09, “Compensation - Stock Compensation (Topic 718) - Scope of Modification Accounting” (“ASU 2017-09”). ASU 2017-09 clarifies when changes to the terms or conditions of a share-based payment award should be accounted for as a modification. This guidance indicates modification accounting is required when the fair value, vesting conditions, or classification of the award changes. ASU 2017-09 will be effective for the Company on January 1, 2018 and is not expected to have a significant impact on its consolidated financial statements. In August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging (Topic 815) - Targeted Improvements to Accounting for Hedging Activities” (“ASU 2017-12”). ASU 2017-12 amends the hedge accounting recognition and presentation requirements in ASC 815 to improve the transparency and understandability of information conveyed to financial statement users about an entity’s risk management activities to better align the entity’s financial reporting for hedging relationships with those risk management activities and to reduce the complexity of and simplify the application of hedge accounting. ASU 2017-12 will be effective for the Company on January 1, 2019 and is not expected to have a significant impact on its consolidated financial statements. In February 2018, the FASB issued ASU No. 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” (“ASU 2018-02”). ASU 2018-02 addresses the income tax accounting treatment of the stranded tax effects within other comprehensive income. The ASU allows for an entity to reclassify the stranded tax effects resulting from the Tax Cuts and Jobs Act from accumulated other comprehensive income to retained earnings. ASU 2018-02 will be effective for the Company on January 1, 2019, with early adoption permitted. The Company will early adopt ASU 2018-02 in the first quarter of 2018 and will reclassify its stranded tax debit of $ 244 thousand within accumulated other comprehensive income to retained earnings at March 31, 2018. Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies are not expected to have a material impact on the Company’s balance sheets, statements of income and cash flows.
