Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	Note 1. Basis of Presentation Nature of Operations Live Oak Bancshares, Inc. (the “Company” or “LOB”) is a bank holding company headquartered in Wilmington, North Carolina incorporated under the laws of the State of North Carolina in December 2008. The Company conducts business operations primarily through its commercial bank subsidiary, Live Oak Banking Company (the “Bank”). The Bank was organized and incorporated under the laws of the State of North Carolina on February 25, 2008 and commenced operations on May 12, 2008. The Bank specializes in lending and deposit related services to small businesses nationwide. The Bank identifies and extends lending to credit-worthy borrowers both within specific industries, also called verticals, through expertise within those industries, and more broadly to select borrowers outside of those industries. A significant portion of the loans originated by the Bank are guaranteed by the Small Business Administration (“SBA”) under the 7(a) Loan Program and the U.S. Department of Agriculture’s ("USDA") Rural Energy for America Program ("REAP"), Water and Environmental Program (“WEP”) and Business & Industry ("B&I") loan programs. The Company’s wholly owned subsidiaries are the Bank, Government Loan Solutions (“GLS”), Live Oak Grove, LLC (the “Grove”), Live Oak Ventures, Inc. (“Live Oak Ventures”), and Canapi Advisors, LLC (“Canapi Advisors”). The Bank’s wholly owned subsidiaries are Live Oak Number One, Inc., Live Oak Clean Energy Financing LLC (“LOCEF”), and Live Oak Private Wealth, LLC. Live Oak Number One, Inc. holds properties foreclosed on by the Bank. LOCEF provides financing to entities for renewable energy applications. Live Oak Private Wealth, LLC and its wholly owned subsidiary, Jolley Asset Management, LLC (“JAM”), provide high-net-worth individuals and families with strategic wealth and investment management services. GLS is a management and technology consulting firm that advises and offers solutions and services to participants in the government guaranteed lending sector. GLS primarily provides services in connection with the settlement, accounting, and securitization processes for government guaranteed loans, including loans originated under the SBA 7(a) loan programs and USDA guaranteed loans. The Grove provides Company employees and business visitors an on-site restaurant location. Live Oak Ventures’ purpose is investing in businesses that align with the Company's strategic initiative to be a leader in financial technology. Canapi Advisors provides investment advisory services to a series of funds focused on providing venture capital to new and emerging financial technology companies. The Company generates revenue primarily from net interest income and secondarily through the origination and sale of government guaranteed loans. Income from the retention of loans is comprised of interest income. The Company had historically elected to account for certain loans under the fair value option with interest reported in interest income and changes in fair value reported in the net (loss) gain on loans accounted for under the fair value option line item of the consolidated statements of income. During the first quarter of 2021, the Company chose not to elect fair value for all retained participating interests arising from new government guaranteed loan sales. Income from the sale of loans is comprised of loan servicing revenue and revaluation of related servicing assets along with net gains on sales of loans. Offsetting these revenues are the cost of funding sources, provision for loan and lease credit losses, any costs related to foreclosed assets and other operating costs such as salaries and employee benefits, travel, professional services, advertising and marketing and tax expense. The Company also has less routinely generated gains and losses arising from its financial technology investments in its fintech segment. General In the opinion of management, all adjustments necessary for a fair presentation of the financial position and results of operations for the periods presented have been included, and all intercompany transactions have been eliminated in consolidation. Results of operations for the nine months ended September 30, 2021 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2021. The Unaudited Condensed Consolidated Balance Sheet as of December 31, 2020 has been derived from the audited consolidated financial statements contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020, filed with the Securities Exchange Commission on February 25, 2021 (SEC File No. 001-37497) (the "2020 Form 10-K"). A summary description of the significant accounting policies followed by the Company is set forth in Note 1 of the Notes to Consolidated Financial Statements in the Company’s 2020 Form 10-K. These unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and footnotes in the Company's 2020 Form 10-K. The preparation of financial statements in conformity with United States generally accepted accounting principles, or GAAP, requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and the reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from those estimates. Amounts in all tables in the Notes to Unaudited Condensed Consolidated Financial Statements have been presented in thousands, except percentage, time period, stock option, share and per share data or where otherwise indicated. Business Segments Operating segments are components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. Management has determined that the Company has two significant operating segments: Banking and Fintech, as discussed more fully in Note 12. Segments. In determining the appropriateness of segment definition, the Company considers the criteria of ASC 280, Segment Reporting . Business Combination On April 1, 2020, the Company acquired 100% of the equity interests of JAM, a registered investment advisor based in Rocky Mount, North Carolina. Goodwill, intangible assets and contingent consideration of $1.8 million, $2.3 million and $2.1 million, respectively, were recorded by the Company. Intangible assets are almost entirely comprised of customer relationships that are being amortized using the straight-line method over 15 years.

The acquisition did not materially impact the Company's financial position, results of operations or cash flows. Given the impact of the above acquisition was immaterial to the Company and its result of operations, pro forma information has not been included. Reclassifications Certain reclassifications have been made to the prior period’s condensed consolidated financial statements to place them on a comparable basis with the current year. Net income and shareholders’ equity previously reported were not affected by these reclassifications .

During the three months ended September 30, 2020, one US government agency matured at $2.0 million, one US Treasury note matured at $5.0 million, and five mortgage-backed securities totaling $10.2 million were sold resulting in a net gain of $1.2 million. During the nine months ended September 30, 2021, one US government agency matured at $5.0 million and eight mortgage-backed securities totaling $23.1 million were settled. During the nine months ended September 30, 2020, two US government agencies matured at $4.5 million, one US Treasury note matured at $5.0 million, eighteen mortgage-backed securities totaling $24.4 million were sold resulting in a net gain of $1.3 million, and two municipal bonds totaling $5.2 million were sold resulting in a net gain of $620 thousand. Accrued interest receivable on available-for-sale securities totaled $1.9 million and $1.8 million at September 30, 2021 and December 31, 2020, respectively, and is included in other assets in the accompanying Unaudited Condensed Consolidated Balance Sheets. The following tables show debt securities available-for-sale in an unrealized loss position for which an allowance for credit losses has not been recorded, aggregated by investment category and length of time that the individual securities have been in a continuous unrealized loss position.

The evaluation considers the extent to which the security’s fair value is less than cost, the financial condition and near-term prospects of the issuer, and intent and ability of the Company to retain its investment in the security for a period of time sufficient to allow for any anticipated recovery in fair value. At September 30, 2021, there were twelve mortgage-backed securities and one municipal bond in unrealized loss positions for greater than 12 months and one hundred twenty two mortgage-backed securities in unrealized loss positions for less than 12 months. Unrealized losses at December 31, 2020 were comprised of three These unrealized losses are primarily the result of non-credit-related volatility in the market and market interest rates. Since none of the unrealized losses relate to marketability of the securities or the issuer’s ability to honor redemption obligations and the Company has the intent and ability to hold the securities for a sufficient period of time to recover unrealized losses, none of the losses have been recognized in the Company’s Unaudited Condensed Consolidated Statements of Income. All mortgage-backed securities in the Company’s portfolio at September 30, 2021 and December 31, 2020 were backed by U.S. government sponsored enterprises (“GSEs”).

Leases

Leases	9 Months Ended

Leases [Abstract]
Leases	Note 6. Leases Lessor Equipment Leasing The Company purchases new equipment for the purpose of leasing such equipment to customers within its verticals. Equipment purchased to fulfill commitments to commercial renewable energy projects is rented out under operating leases while leases of equipment outside of the renewable energy vertical are generally direct financing leases. Accordingly, leased assets under operating leases are included in premises and equipment while leased assets under direct financing leases are included in loans and leases held for investment. Direct Financing Leases Interest income on direct financing leases is recognized when earned. Unearned interest is recognized over the lease term on a basis which results in a constant rate of return on the unrecovered lease investment. The term of each lease is generally 3-7 years which is consistent with the useful life of the equipment with no residual value. The gross lease payments receivable and the net investment included in accounts receivable for such leases are as follows: September 30, 2021 December 31, 2020 Gross direct finance lease payments receivable $ 8,276 $ 10,629 Less – unearned interest (1,159 ) (1,685 ) Net investment in direct financing leases $ 7,117 $ 8,944 Future minimum lease payments under finance leases are as follows: As of September 30, 2021 Amount 2021 $ 683 2022 2,620 2023 2,182 2024 1,570 2025 1,104 Thereafter 117 Total $ 8,276 Interest income of $159 thousand and $199 thousand was recognized in the three months ended September 30, 2021 and 2020, respectively. Interest income of $517 thousand and $644 thousand was recognized in the nine months ended September 30, 2021 and 2020, respectively. Operating Leases The term of each operating lease is generally 10 to 15 years. The Company retains ownership of the equipment and associated tax benefits such as investment tax credits and accelerated depreciation. At the end of the lease term, the lessee has the option to renew the lease for two additional terms or purchase the equipment at the then-current fair market value. Rental revenue from operating leases is recognized on a straight-line basis over the term of the lease. Rental equipment is recorded at cost and depreciated to an estimated residual value on a straight-line basis over the estimated useful life. The useful lives generally range from 20 to 25 years and residual values generally range from 20% to 50%, however, they are subject to periodic evaluation. Changes in useful lives or residual values will impact depreciation expense and any gain or loss from the sale of used equipment. The estimated useful lives and residual values of the Company's leasing equipment are based on industry disposal experience and the Company's expectations for future sale prices. If the Company decides to sell or otherwise dispose of rental equipment, it is carried at the lower of cost or fair value less costs to sell or dispose. Repair and maintenance costs that do not extend the lives of the rental equipment are charged to direct operating expenses at the time the costs are incurred. As of September 30, 2021 and December 31, 2020, the Company had a net investment of $126.3 million and $134.5 million, respectively, in assets included in premises and equipment that are subject to operating leases. Of the net investment, the gross balance of the assets was $163.4 million and $164.3 million as of September 30, 2021 and December 31, 2020, respectively, and accumulated depreciation was $37.1 million and $29.8 million as of September 30, 2021 and December 31, 2020, respectively. Depreciation expense recognized on these assets for the three and nine months ended September 30, 2021 and 2020 was $2.4 $7.3 Lease income of $2.4 million was recognized in the three months ended September 30, 2021 and 2020. Lease income of $7.2 million and $7.1 million were recognized in the nine months ended September 30, 2021 and 2020, respectively. A maturity analysis of future minimum lease payments to be received under non-cancelable operating leases is as follows: As of September 30, 2021 Amount 2021 $ 1,969 2022 9,044 2023 9,075 2024 8,808 2025 8,935 Thereafter 31,175 Total $ 69,006

Transfers And Servicing [Abstract]
Servicing Assets	Note 7. Servicing Assets Loans serviced for others are not included in the accompanying Unaudited Condensed Consolidated Balance Sheets. The unpaid principal balances of loans serviced for others requiring recognition of a servicing asset were $2.26 billion and $2.21 billion at September 30, 2021 and December 31, 2020, respectively. The unpaid principal balance for all loans serviced for others was $3.21 billion at September 30, 2021 and December 31, 2020. The following summarizes the activity pertaining to servicing rights: Three Months Ended September 30, Nine Months Ended September 30, 2021 2020 2021 2020 Balance at beginning of period $ 36,966 $ 33,834 $ 33,918 $ 35,365 Additions, net 2,880 1,936 7,616 6,668 Fair value changes: Due to changes in valuation inputs or assumptions (2,768 ) 3,758 119 1,596 Decay due to increases in principal paydowns or runoff (3,110 ) (1,697 ) (7,685 ) (5,798 ) Balance at end of period $ 33,968 $ 37,831 $ 33,968 $ 37,831 The fair value of servicing rights was determined using a weighted average discount rate of 12.3% on September 30, 2021 and 9.1% on September 30, 2020. The fair value of servicing rights was determined using a weighted average prepayment speed of 16.7% on September 30, 2021 and 19.1% on September 30, 2020, with the actual rate depending on the stratification of the specific right. Changes to fair value are reported in loan servicing asset revaluation within the Unaudited Condensed Consolidated Statements of Income. The fair value of servicing rights is highly sensitive to changes in underlying assumptions. Changes in prepayment speed assumptions typically have the most significant impact on the fair value of servicing rights. Generally, as interest rates rise on variable rate loans, loan prepayments increase due to an increase in refinance activity, which results in a decrease in the fair value of servicing assets, however, weakening economic conditions or significant declines in interest rates can also increase loan prepayment activity. Measurement of fair value is limited to the conditions existing and the assumptions used as of a particular point in time, and those assumptions may not be appropriate if they are applied at a different time.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Note 9. Fair Value of Financial Instruments Fair Value Hierarchy There are three levels of inputs in the fair value hierarchy that may be used to measure fair value. Financial instruments are considered Level 1 when valuation can be based on quoted prices in active markets for identical assets or liabilities. Level 2 financial instruments are valued using quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or models using inputs that are observable or can be corroborated by observable market data of substantially the full term of the assets or liabilities. Financial instruments are considered Level 3 when their values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable and when determination of the fair value requires significant management judgment or estimation. Recurring Fair Value The following sections provide a description of the valuation methodologies used for instruments measured at fair value on a recurring basis, as well as the general classification of such instruments pursuant to the fair value hierarchy: Investment securities: Where quoted prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities would include highly liquid government bonds, mortgage products and exchange traded equities. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics, discounted cash flow or at net asset value per share. Level 2 securities would include U.S. government agency securities, mortgage-backed securities, obligations of states and political subdivisions and certain corporate, asset backed mutual fund and other securities. In certain cases where there is limited activity or less transparency around inputs to the valuation, securities are classified within Level 3 of the valuation hierarchy. Loans held for sale: The fair values of loans held for sale are determined by discounting estimated cash flows using interest rates approximating prevailing market rates for similar loans adjusted to reflect the inherent credit risk. Due to the nature of the valuation inputs, loans held for sale are classified within Level 3 of the valuation hierarchy. Loans held for investment: The fair values of loans held for investment are typically determined based on discounted cash flow analyses using market-based interest rate spreads. Discounted cash flow analyses are adjusted, as appropriate, to reflect current market conditions and borrower-specific credit risk. If the loan is collateral dependent, the fair value is determined based on the difference between the fair value of the collateral and the amortized cost basis of the loan as of the measurement date. Fair value of the loan’s collateral is determined by appraisals, independent valuation, or management’s estimation of fair value which is then adjusted for the cost related to liquidation of the collateral. Due to the nature of the valuation inputs, loans held for investment are classified within Level 3 of the valuation hierarchy. Servicing assets: Servicing rights do not trade in an active, open market with readily observable prices. While sales of servicing rights do occur, the precise terms and conditions typically are not readily available. Accordingly, the Company estimates the fair value of servicing rights using discounted cash flow models incorporating numerous assumptions from the perspective of a market participant including servicing income, servicing costs, market discount rates and prepayment speeds. Due to the nature of the valuation inputs, servicing rights are classified within Level 3 of the valuation hierarchy. Mutual fund: The below mutual fund is registered with the Securities and Exchange Commission as a closed-end, non-diversified management investment company and operates as an interval fund. The fund primarily invests in the unguaranteed portion of SBA504 First Lien Loans secured by owner-occupied commercial real estate. This investment is valued using quoted prices in markets that are not active and is classified as Level 2 within the valuation hierarchy. Equity warrant assets: Fair value measurements of equity warrant assets of private companies are priced based on a Black-Scholes option pricing model to estimate the asset value by using stated strike prices, option expiration dates, risk-free interest rates and option volatility assumptions. Option volatility assumptions used in the Black-Scholes model are based on public companies that operate in similar industries as the companies in the Company’s private company portfolio. Option expiration dates are modified to account for estimates of actual life relative to stated expiration. Values are further adjusted for a general lack of liquidity due to the private nature of the associated underlying company.

(2) See Note 7 for a rollforward of recurring Level 3 fair values for servicing assets. Fair Value Option The Company has historically elected to account for retained participating interests of all government guaranteed loans under the fair value option in order to align the accounting presentation with the Company’s viewpoint of the economics of the loans. Interest income on loans accounted for under the fair value option is recognized in loans and fees on loans on the Company’s Unaudited Condensed Consolidated Statements of Income. Beginning in the first quarter of 2021, the Company chose not to elect fair value for all retained participating interests arising from new government guaranteed loan sales. Not electing fair value generally results in a larger discount being recorded on the date of the sale. This discount is subsequently accreted into interest income over the underlying loan’s remaining term using the effective interest method. Management made this change of election in alignment with its ongoing effort to reduce volatility and drive more predictable revenue. In accordance with accounting standards, any loans for which fair value was previously elected will continue to be measured as such There were no loans accounted for under the fair value option that were 90 days or more past due and still accruing interest at September 30, 2021 or December 31, 2020. The unpaid principal balance of unguaranteed exposure for nonaccruals was $7.9 million and $6.9 million at September 30, 2021 and December 31, 2020, respectively. The following tables provide more information about the fair value carrying amount and the unpaid principal outstanding of loans accounted for under the fair value option at September 30, 2021 and December 31, 2020.

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

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 10. Commitments and Contingencies Litigation In the normal course of business, the Company is involved in various legal proceedings. Management believes that the outcome of such proceedings will not materially affect the financial position, results of operations or cash flows of the Company. On March 12, 2021, a purported class action was filed against the Company in the United States District Court for the Eastern District of North Carolina, Joseph McAlear, individually and on behalf of all others similarly situated v. Live Oak Bancshares, Inc. et al. Financial Instruments with Off-balance-sheet Risk The Company is party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments involve, to varying degrees, credit risk in excess of the amount recognized in the balance sheet. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as for on-balance-sheet instruments. A summary of the Company’s commitments is as follows: September 30, 2021 December 31, 2020 Commitments to extend credit $ 2,687,933 $ 2,054,910 Standby letters of credit 9,150 22,913 Total unfunded off-balance-sheet credit risk $ 2,697,083 $ 2,077,823 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the party. Collateral held varies, but may include accounts receivable, inventory, property and equipment, residential real estate and income-producing commercial properties. Commitment letters are issued after approval of the loan by the Credit Department and generally expire ninety days after issuance. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. Collateral held varies as specified above and is required in instances which the Company deems necessary. The balance of the allowance for off-balance sheet credit exposures was $611 thousand and $746 thousand at September 30, 2021 and December 31, 2020, respectively. As of September 30, 2021 and December 31, 2020, the Company had unfunded commitments to provide capital contributions for on-balance-sheet investments in the amount of $11.0 million and $15.8 million, respectively. Concentrations of Credit Risk The distribution of commitments to extend credit approximates the distribution of loans outstanding. The Company does not have a significant number of credits to any single borrower or group of related borrowers whereby their retained unguaranteed exposure exceeds $15.0 million, except for 25 relationships that have a retained unguaranteed exposure of $637.7 million of which $284.8 million of the unguaranteed exposure has been disbursed. Additionally, the Company has future minimum lease payments receivable under non-cancelable operating leases totaling $69.0 million, of which $21.2 million is due from one relationship. The Company from time-to-time may have cash and cash equivalents on deposit with financial institutions that exceed federally-insured limits.

For the three months ended September 30, 2021, 339,118 RSUs were granted with a weighted average grant date fair value of $61.11. For the nine months ended September 30, 2021, 1,155,694 RSUs were granted with a weighted average grant date fair value of $54.01. Of the RSUs granted in the nine-month period, 288,680 were awarded in connection with annual long term incentive stock compensation and 500,000 were awarded as a special retention RSU award. At September 30, 2021, unrecognized compensation costs relating to RSUs amounted to $67.0 million which will be recognized over a weighted average period of 4.80 years.

Segment Reporting [Abstract]
Segments	Note 12. Segments The Company's management reporting process measures the performance of its operating segments based on internal operating structure, which is subject to change from time to time. Accordingly, the Company operates two reportable segments for management reporting purposes as discussed below: Banking - This segment specializes in providing financing services to small businesses nationwide in targeted industries and deposit-related services to small businesses, consumers and other customers nationwide. The primary source of revenue for this segment is net interest income and secondarily the origination and sale of government guaranteed loans. Fintech - This segment is involved in making strategic investments into emerging financial technology companies. The primary sources of revenue for this segment are principally gains and losses on equity method and equity security investments and management fees. The Fintech segment is comprised of the Company's wholly owned subsidiaries Live Oak Ventures and Canapi Advisors, and the investments held by those entities, as well as the Bank's investment in Apiture. The following tables provide financial information for the Company's segments. The information provided under the caption “Other” represents operations not considered to be reportable segments and/or general operating expenses of the Company, and includes the parent company, other non-bank subsidiaries and elimination adjustments to reconcile the results of the operating segments to the unaudited condensed consolidated financial statements prepared in conformity with GAAP.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
General	General In the opinion of management, all adjustments necessary for a fair presentation of the financial position and results of operations for the periods presented have been included, and all intercompany transactions have been eliminated in consolidation. Results of operations for the nine months ended September 30, 2021 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2021. The Unaudited Condensed Consolidated Balance Sheet as of December 31, 2020 has been derived from the audited consolidated financial statements contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020, filed with the Securities Exchange Commission on February 25, 2021 (SEC File No. 001-37497) (the "2020 Form 10-K"). A summary description of the significant accounting policies followed by the Company is set forth in Note 1 of the Notes to Consolidated Financial Statements in the Company’s 2020 Form 10-K. These unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and footnotes in the Company's 2020 Form 10-K. The preparation of financial statements in conformity with United States generally accepted accounting principles, or GAAP, requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and the reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from those estimates.
