Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Description of Business, Basis of Presentation, Use of Estimates and Recently Adopted Accounting Pronouncements	Organization, Description of Business, Basis of Presentation, Use of Estimates and Recently Adopted Accounting Pronouncements Organization and Description of Business Outbrain Inc., together with its subsidiaries, (“Outbrain”, the “Company”, “we”, “our” or “us”) was incorporated in August 2006 in Delaware. The Company is headquartered in New York, New York and has wholly owned subsidiaries in Israel, Europe, Asia, Brazil and Australia. In connection with the Company’s initial public offering (“IPO”), its common stock began trading on The Nasdaq Stock Market LLC (“Nasdaq”) on July 23, 2021 under “OB” ticker. Outbrain is a leading recommendation platform powering the open web. The Company’s platform provides personalized recommendations that appear as links to content, advertisements and videos on media owners’ online properties. The Company generates revenue from marketers through user engagements with promoted recommendations that it delivers across a variety of third-party media owners’ properties. The Company pays traffic acquisition costs to its media owner partners on whose digital properties the recommendations are shown. The Company’s advertiser solutions are mainly priced using a performance-based model based on the actual number of engagements generated by users, which is highly dependent on its ability to generate trustworthy and interesting recommendations to individual users based on its proprietary algorithms. A small portion of the Company’s revenue is generated through advertisers participating in programmatic auctions wherein the pricing is determined by the auction results and not dependent on user engagement. Basis of Presentation The accompanying condensed consolidated financial statements were prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information and are unaudited. Certain information and disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. Accordingly, these condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, filed with the Securities and Exchange Commission on March 18, 2022 ("2021 Form 10-K"). Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and related disclosures as of the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Estimates and judgments are based on historical information and on various other assumptions that the Company believes are reasonable under the circumstances. Estimates and assumptions made in the accompanying condensed consolidated financial statements include, but are not limited to, the allowance for doubtful accounts, sales allowance, software development costs eligible for capitalization, valuation of deferred tax assets, the useful lives of property and equipment, the useful lives and fair value of intangible assets and goodwill, the fair value of stock-based awards, and the recognition and measurement of income tax uncertainties and other contingencies. Actual results could differ materially from these estimates. Reclassifications Certain reclassifications have been made to the prior periods’ financial information in order to conform to the current period’s presentation. Certain Risks and Concentrations Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents, restricted cash and accounts receivable. The Company’s cash and cash equivalents and restricted cash are generally invested in high-credit quality financial instruments with both banks and financial institutions to reduce the amount of exposure to any single financial institution. The Company generally does not require collateral to secure its accounts receivable. No single marketer accounted for 10% or more of the Company’s total revenue for the three months ended March 31, 2022 or 2021, or for 10% or more of its gross accounts receivable balance as of March 31, 2022 or December 31, 2021. During the three months ended March 31, 2022, one media owner accounted for approximately 10% of the Company’s total traffic acquisition costs. For the three months ended March 31, 2021, two media owners individually accounted for approximately 12% and 10% of the Company’s total traffic acquisition costs. Segment Information The Company has one operating and reporting segment. The Company’s chief operating decision maker is its Co-Chief Executive Officer who makes resource allocation decisions and assesses performance based on financial information presented on a consolidated basis. New Accounting Pronouncements Under the JOBS Act, the Company meets the definition of an emerging growth company and can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the Company is no longer an emerging growth company or until the Company affirmatively and irrevocably opts out of the extended transition period. Recently Adopted Accounting Pronouncements Leases In February 2016, the Financial Accounting Standards Board (the “FASB”) issued ASU 2016-02, “Leases (Topic 842)”, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). This comprehensive new standard amends and supersedes existing lease accounting guidance and is intended to increase transparency and comparability by recognizing right-of-use (“ROU”) lease assets and lease liabilities on the balance sheet and requiring disclosure of key information about leasing arrangements. In July 2018, this guidance was amended to allow companies to use the beginning of the period in which this standard is adopted as the date of initial application. The Company adopted Topic 842 on January 1, 2022 using the transition election allowing it not to restate prior periods. As such, results for reporting periods beginning on January 1, 2022 are presented under Topic 842, while prior period amounts continue to be reported in accordance with the Company’s historical accounting treatment under ASC 840, Leases. The Company elected the package of practical expedients permitted under the transition guidance, which allows not to reassess its prior conclusions about lease identification, lease classification and initial direct costs. In addition, the Company elected not to separate the lease and non-lease components for its real estate leases and not to recognize lease assets and liabilities for operating leases with initial terms of 12 months or less. The Company did not elect the “hindsight” practical expedient. The Company uses its incremental borrowing rate to determine the present value of lease payments, as the Company’s leases do not have a readily determinable implicit discount rate. The incremental borrowing rate is the rate of interest the Company would have to pay to borrow on a collateralized basis over a similar term and amount in a similar economic environment. Upon adoption, the Company recognized operating right of use assets of $14.8 million and operating lease liabilities of $15.2 million in its consolidated balance sheet as of January 1, 2022. In addition, the Company reclassified deferred rent and lease incentives as a component of right-of-use assets. The adoption of the new lease standard did not have a material impact the Company’s results of operations or cash flows and there was no cumulative-effect adjustment to the opening balance of retained earnings. Credit Losses In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326),” which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss model which requires consideration of forward-looking information to calculate credit loss estimates. These changes will result in an earlier recognition of credit losses. The Company's financial assets held at amortized cost include accounts receivable. The amendments in ASU 2020-05 deferred the effective date for Topic 326 to fiscal years beginning after December 15, 2 022. The Company early adopted ASU 2016-13 as of January 1, 2022, using the adoption method based on the aging schedules of accounts receivable. The adoption of this standard did not have a material impact on the Company’s condensed consolidated financial statements. See Note 1 to the Company’s audited consolidated financial statements for the year ended December 31, 2021 in the Company’s 2021 Form 10-K for a complete disclosure of the Company’s significant accounting policies.

Business Combination and Asset Acquisition [Abstract]
Acquisition	Acquisition On November 19, 2021, the Company entered into a definitive agreement, by and among the Company and the shareholders of video intelligence AG (“vi”), a Swiss-based contextual video technology company for digital media owners, for the acquisition of all of the outstanding shares of vi for a purchase price of approximately $55 million. The acquisition was completed on January 5, 2022. The purchase price was paid in the form of cash and Outbrain common stock, with the first installment of $37.3 million in cash and the equity portion paid at closing, and the substantial majority of the remaining cash balance payable in the third quarter of 2022. The equity portion of the purchase price was comprised of 355,786 shares of the Company’s common stock with a fair value of $4.2 million, and is subject to a post-closing adjustment based on market price of our stock to be determined one year from closing, at which time any required adjustment is to be paid in cash. Aggregate consideration for the acquisition of vi will not exceed approximately $55 million in total. This acquisition expands the Company’s video product offerings to include in-stream high-quality video content, delivering a better user experience and more value to its advertisers. The following table summarizes the total purchase consideration as of the acquisition date: January 5, 2022 (in thousands) Cash consideration paid on acquisition date $ 37,311 Fair value of deferred consideration payable in cash 10,936 Fair value of contingent consideration payable 547 Stock consideration 4,190 Total consideration $ 52,984 This acquisition was accounted for as a business combination under the acquisition method of accounting and the results of operations of vi have been included in the Company’s results of operations as of the acquisition date. The Company incurred transaction costs relating to the vi acquisition of $0.2 million during the three months ended March 31, 2022, which were included in general and administrative expenses in the Company’s condensed consolidated statements of operations. The Company allocated the purchase price to identifiable assets acquired based on their estimated fair values at acquisition date, which required management to use significant judgment and estimates, including valuation methodologies, estimates of future revenue, cost and cash flows, discount rates, and identifying comparable companies. The Company engaged third-party valuation specialists to assist in determining the fair values of the acquired assets and liabilities. The preliminary allocation of the purchase price to the identifiable assets and liabilities based on their estimated fair values as of the acquisition date was as follows: January 5, 2022 (in thousands) Cash and cash equivalents $ 2,787 Accounts receivable 3,849 Prepaid expenses and other current assets 995 Property and equipment, net 43 Publisher relationships 10,783 Customer relationships 732 Content provider relationships 284 Technology intangibles 9,985 Trademark 3,704 Accounts payable (2,571) Accrued and other liabilities (2,768) Deferred tax liability (5,021) Net assets acquired 22,802 Goodwill 30,182 Total $ 52,984 The fair values of the publisher relationships were determined using the multi-period excess earnings income approach and the fair values of the customer and content provider relationships were determined using the cost approach. The fair value of trade names and technology was determined using the relief-from-royalty method. Identifiable intangible assets acquired are amortized on a straight-line basis over their estimated useful lives. The Company estimated useful lives of acquired publisher relationships and technology to be 8 years, and tradenames to be 9 years, and other relationships to be 5 years. Amortization expense for amortizable intangible assets is included within sales and marketing expense in the Company’s condensed consolidated statement of operations.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company’s financial instruments include restricted time deposits, severance pay fund deposits and foreign currency forward contract assets. The Company determines the fair value of its financial instruments based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the Company uses the fair value hierarchy described below to distinguish between observable and unobservable inputs: Level I — Valuations based on quoted prices in active markets for identical assets and liabilities at the measurement date; Level II — Valuations based on quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be principally corroborated by observable market data for substantially the full term of the related assets or liabilities; and Level III — Valuations based on unobservable inputs that are significant to the measurement of the fair value of the assets or liabilities that are supported by little or no market data. The following table sets forth the fair value of the Company’s financial assets measured on a recurring basis by level within the fair value hierarchy: March 31, 2022 Level I Level II Level III Total (In thousands) Financial Assets: Restricted time deposit (1) $ — $ 191 $ — $ 191 Severance pay fund deposits (1) $ — $ 5,897 $ — $ 5,897 Foreign currency forward contract (2) $ — $ 6 $ — $ 6 Total financial assets $ — $ 6,094 $ — $ 6,094 December 31, 2021 Level I Level II Level III Total (In thousands) Financial Assets: Restricted time deposit (1) $ — $ 195 $ — $ 195 Severance pay fund deposits (1) $ — $ 6,086 $ — $ 6,086 Foreign currency forward contract (2) $ — $ 741 $ — $ 741 Total financial assets $ — $ 7,022 $ — $ 7,022 _____________________ (1) Recorded within other assets (2) Recorded within prepaid expenses and other current assets The Company’s 2.95% Convertible Senior Notes due 2026 (“Convertible Notes”) are recorded within long-term debt in its condensed consolidated balance sheets at their carrying value, which may differ from their fair value. The fair value of Convertible Notes is estimated using external pricing data, including any available market data for other debt instruments with similar characteristics.

Leases [Abstract]
Leases	Leases The Company leases certain equipment and computers under finance lease arrangements, as well as office facilities and managed data center facilities under non-cancelable operating lease arrangements for its U.S. and international locations that expire on various dates through 2031. These arrangements require the Company to pay certain operating expenses, such as taxes, repairs and insurance and contain renewal and escalation clauses. The Company’s options to extend or terminate a lease are not included in the lease terms, unless the Company is reasonably certain it will exercise that option. The Company’s leases generally do not contain any material restrictive covenants. The Company’s minimum lease payments include fixed payments for non-lease components included in the lease agreement, but exclude variable lease payments that are not dependent on an index or rate, such as common area maintenance, operating expenses, utilities, or other costs that are subject to fluctuations from period to period. Non-lease components that are variable in nature are recorded as variable lease expenses in the period incurred.

Debt Disclosure [Abstract]
Long Term Debt	Long-Term Debt Convertible Notes On July 27, 2021, in connection with the closing of the Company’s IPO and pursuant to the terms of the Note Purchase Agreement, the Company exchanged $200 million aggregate principal amount of its senior subordinated secured notes due July 1, 2026 for $236 million aggregate principal amount of 2.95% Convertible Senior Notes due 2026 (the “Convertible Notes”), pursuant to an indenture, dated as of July 27, 2021 (the “Indenture”), between the Company and The Bank of New York Mellon, as trustee. The Convertible Notes will mature on July 27, 2026, unless earlier converted, redeemed or repurchased. Interest on the Convertible Notes accrues from July 27, 2021 an d is payable semi-annually in arrears on January 27 and July 27 of each year, beginning on January 27, 2022 , at a rate of 2.95% per year. The initial conversion rate for the Convertible Notes is 40 shares of the Company’s common stock per $1,000 principal amount of Convertible Notes (equivalent to an initial conversion price o f $25 per share of the Company’s common stock), subject to adjustment. The Company may not redeem the Convertible Notes prio r to July 27, 2024. On or after July 27, 2024 , the Company may redeem for cash all or any portion of the Convertible Notes, at its option, if the last reported sale price of the common stock has been at lea st 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption at a redemption price equal t o 100% of the principal amount of the Convertible Notes to be redeemed plus accrued and unpaid interest to, but excluding, the redemption date. In addition, calling any Convertible Note for redemption will constitute a “make-whole fundamental change” (as defined in the Indenture) with respect to that Convertible Note, in which case the conversion rate applicable to the conversion of that Convertible Note will be increased if it is converted by holders after it is called for redemption. Holders may convert all or any portion of their Convertible Notes, in multiple s of $1,000 princip al amount, into shares of the Company’s common stock at any time until the second scheduled trading day immediately preceding the maturity date, at the conversion rate then in effect. The Company will settle conversions of the Convertible Notes by paying or delivering, as the case may be, cash, shares of common stock, or a combination thereof, at its election. Upon the occurrence of a fundamental change (as defined in the Indenture), subject to certain conditions, holders of the Convertible Notes may require the Company to repurchase for cash all or any portion of their Convertible Notes in principal amounts of $1,000 or an integral multiple thereof, at a repurchase price of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the repurchase date. In addition, following certain corporate events that occur prior to the maturity date or if the Company delivers a notice of redemption, the Company will, in certain circumstances, increase the conversion rate for a holder who elects to convert its Convertible Notes in connection with such a corporate event or convert its Convertible Notes called for redemption during the related redemption period, as the case may be. The Indenture contains customary covenants and events of default. The Company was not required to bifurcate the embedded conversion feature and the Convertible Notes were not issued with a substantial premium. As such, the Company accounted for the Convertible Notes as a liability under the no proceeds allocated model. The Company calculates earnings per share using the if-converted method. Revolving Credit Facility On November 2, 2021, the Company entered into the Second Amended and Restated Loan and Security Agreement with Silicon Valley Bank (“SVB”) (the “2021 Revolving Credit Facility”), which provides, subject to borrowing availability and certain other conditions, for revolving loans in an aggregate principal amount of up to $75.0 million (the “Facility”), with a $15.0 million sub-facility for letters of credit. The Company’s borrowing availability under the Facility is calculated by reference to a borrowing base which is determined by specified percentages of eligible accounts receivable. The Facility will terminate on the earlier of (i) November 2, 2026 or (ii) 120 days prior to the maturity date of the Company’s 2.95% Convertible Senior Notes due 2026, unless the Convertible Notes have been converted to common equity securities of the Company. Outstanding loans under the Facility accrue interest, at the Company’s option, at a rate equal to either (a) a base rate minus an applicable margin ranging from 1.5% to 1.0% per annum or (b) LIBOR plus an applicable margin of 1.5% to 2.0% per annum, in each case based upon borrowing availability under the Facility. The undrawn portions of the commitments under the Facility are subject to a commitment fee at a rate ranging from 0.20% per annum to 0.30% per annum, based upon borrowing availability under the Facility. The 2021 Revolving Credit Facility contains representations and warranties, including, without limitation, with respect to collateral; accounts receivable; financials; litigation, indictment and compliance with laws; disclosure and no material adverse effect, each of which is a condition to funding. Additionally, the 2021 Revolving Credit Facility includes events of default and customary affirmative and negative covenants applicable to the Company and its subsidiaries, including, without limitation, restrictions on liens, indebtedness, investments, fundamental changes, dispositions, restricted payments and prepayment of the Convertible Notes and of junior indebtedness. The 2021 Revolving Credit Facility contains a financial covenant that requires, in the event that credit extensions under the Facility equal or exceed 85% of the available commitments under the Facility or upon the occurrence of an event of default, the Company to maintain a minimum consolidated monthly fixed charge coverage ratio of 1.00. The obligations of the Company, and the other subsidiary co-borrowers under the 2021 Revolving Credit Facility are secured by a first-priority lien on substantially all the assets of the Company and such other subsidiary co-borrowers. The Company was in compliance with all of the financial covenants under its 2021 Revolving Credit Facility as of March 31, 2022. As of March 31, 2022 and December 31, 2021, the Company had no borrowings outstanding under its revolving credit facilities and its available borrowing capacity was $69.8 million and $75.0 million. respectively, based on the defined borrowing formula.

Certain information and disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. Accordingly, these condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, filed with the Securities and Exchange Commission on March 18, 2022 ("2021 Form 10-K").
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and related disclosures as of the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Estimates and judgments are based on historical information and on various other assumptions that the Company believes are reasonable under the circumstances. Estimates and assumptions made in the accompanying condensed consolidated financial statements include, but are not limited to, the allowance for doubtful accounts, sales allowance, software development costs eligible for capitalization, valuation of deferred tax assets, the useful lives of property and equipment, the useful lives and fair value of intangible assets and goodwill, the fair value of stock-based awards, and the recognition and measurement of income tax uncertainties and other contingencies. Actual results could differ materially from these estimates.
Reclassifications	Reclassifications Certain reclassifications have been made to the prior periods’ financial information in order to conform to the current period’s presentation.
Certain Risks and Concentrations	Certain Risks and Concentrations Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents, restricted cash and accounts receivable. The Company’s cash and cash equivalents and restricted cash are generally invested in high-credit quality financial instruments with both banks and financial institutions to reduce the amount of exposure to any single financial institution. During the three months ended March 31, 2022, one media owner accounted for approximately 10%
Segment Information	Segment InformationThe Company has one operating and reporting segment. The Company’s chief operating decision maker is its Co-Chief Executive Officer who makes resource allocation decisions and assesses performance based on financial information presented on a consolidated basis.
New Accounting Pronouncements	New Accounting Pronouncements Under the JOBS Act, the Company meets the definition of an emerging growth company and can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the Company is no longer an emerging growth company or until the Company affirmatively and irrevocably opts out of the extended transition period. Recently Adopted Accounting Pronouncements Leases In February 2016, the Financial Accounting Standards Board (the “FASB”) issued ASU 2016-02, “Leases (Topic 842)”, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). This comprehensive new standard amends and supersedes existing lease accounting guidance and is intended to increase transparency and comparability by recognizing right-of-use (“ROU”) lease assets and lease liabilities on the balance sheet and requiring disclosure of key information about leasing arrangements. In July 2018, this guidance was amended to allow companies to use the beginning of the period in which this standard is adopted as the date of initial application. The Company adopted Topic 842 on January 1, 2022 using the transition election allowing it not to restate prior periods. As such, results for reporting periods beginning on January 1, 2022 are presented under Topic 842, while prior period amounts continue to be reported in accordance with the Company’s historical accounting treatment under ASC 840, Leases. The Company elected the package of practical expedients permitted under the transition guidance, which allows not to reassess its prior conclusions about lease identification, lease classification and initial direct costs. In addition, the Company elected not to separate the lease and non-lease components for its real estate leases and not to recognize lease assets and liabilities for operating leases with initial terms of 12 months or less. The Company did not elect the “hindsight” practical expedient. The Company uses its incremental borrowing rate to determine the present value of lease payments, as the Company’s leases do not have a readily determinable implicit discount rate. The incremental borrowing rate is the rate of interest the Company would have to pay to borrow on a collateralized basis over a similar term and amount in a similar economic environment. Upon adoption, the Company recognized operating right of use assets of $14.8 million and operating lease liabilities of $15.2 million in its consolidated balance sheet as of January 1, 2022. In addition, the Company reclassified deferred rent and lease incentives as a component of right-of-use assets. The adoption of the new lease standard did not have a material impact the Company’s results of operations or cash flows and there was no cumulative-effect adjustment to the opening balance of retained earnings. Credit Losses In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326),” which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss model which requires consideration of forward-looking information to calculate credit loss estimates. These changes will result in an earlier recognition of credit losses. The Company's financial assets held at amortized cost include accounts receivable. The amendments in ASU 2020-05 deferred the effective date for Topic 326 to fiscal years beginning after December 15, 2 022. The Company early adopted ASU 2016-13 as of January 1, 2022, using the adoption method based on the aging schedules of accounts receivable. The adoption of this standard did not have a material impact on the Company’s condensed consolidated financial statements. See Note 1 to the Company’s audited consolidated financial statements for the year ended December 31, 2021 in the Company’s 2021 Form 10-K for a complete disclosure of the Company’s significant accounting policies.
Accounts Receivable and Allowance for Credit Losses	Accounts Receivable and Allowance for Credit LossesThe allowance for credit losses is based on the best estimate of the amount of probable credit losses in accounts receivable. The allowance for credit losses is determined based on historical collection experience, reasonable and supportable forecasted information, and any applicable market conditions. The allowance for credit losses also takes into consideration the Company’s current customer information, collection history, and other relevant data. The Company reviews the allowance for credit losses on a quarterly basis. Account balances are written off against the allowance when it is deemed probable that the receivable will not be recovered.
Leases	The Company leases certain equipment and computers under finance lease arrangements, as well as office facilities and managed data center facilities under non-cancelable operating lease arrangements for its U.S. and international locations that expire on various dates through 2031. These arrangements require the Company to pay certain operating expenses, such as taxes, repairs and insurance and contain renewal and escalation clauses. The Company’s options to extend or terminate a lease are not included in the lease terms, unless the Company is reasonably certain it will exercise that option. The Company’s leases generally do not contain any material restrictive covenants. The Company’s minimum lease payments include fixed payments for non-lease components included in the lease agreement, but exclude variable lease payments that are not dependent on an index or rate, such as common area maintenance, operating expenses, utilities, or other costs that are subject to fluctuations from period to period. Non-lease components that are variable in nature are recorded as variable lease expenses in the period incurred.
