Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Description of Business and Summary of Significant Accounting Policies	Organization, Description of Business and Summary of Significant Accounting Policies 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 with various wholly-owned subsidiaries, including in Israel, Europe and Asia. 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 the “OB” ticker symbol. 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’ online 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 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, 2022, filed with the Securities and Exchange Commission on March 15, 2023 (“2022 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 credit losses, 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, valuation of 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. Cash and Cash Equivalents and Investments The Company considers all highly liquid investments with maturities of three months or less when purchased to be cash equivalents. Cash and cash equivalents consist of cash on hand and highly liquid investments in money market funds, U.S. government bonds and commercial paper. Most of our cash deposits are above the $250,000 Federal Deposit Insurance Corporation (“FDIC”) limit and, therefore, not insured. The Company’s investments in debt securities are classified as available-for-sale and are recorded at fair value. The Company classifies its investments in debt securities as short-term or long-term, based on each security’s maturity date. Unrealized gains and losses on available-for-sale securities are recognized in other comprehensive (loss) income (“OCI”), net of taxes. Restricted Cash Restricted cash represents security deposits for facility leases and is included in other assets in the accompanying condensed consolidated balance sheets. 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 accounts receivable. No single marketer accounted for 10% or more of the Company’s total revenue for the three months ended March 31, 2023 or March 31, 2022, or 10% or more of its gross accounts receivable balance as of March 31, 2023 and 2022. During the three months ended March 31, 2023, none of the Company’s media owners accounted for 10% of its total traffic acquisition costs. During the three months ended March 31, 2022, one media owner accounted for 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 Issued Accounting Pronouncements The Company has considered all new accounting pronouncements and has concluded that based on the current information, there are no new pronouncements that are expected to have a material impact on its results of operations, financial condition, or cash flows. See Note 1 to the Company’s audited consolidated financial statements for the year ended December 31, 2022 in the Company’s 2022 Form 10-K for a complete disclosure of the Company’s significant accounting policies.

Fair Value Measurements

Fair Value Measurements	3 Months Ended

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 contracts. 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 and liabilities measured on a recurring basis by level within the fair value hierarchy: March 31, 2023 Level I Level II Level III Total (In thousands) Financial Assets: Cash equivalents and investments (1) $ 31,566 $ 244,480 $ — $ 276,046 Restricted time deposit (2) — 187 — 187 Severance pay fund deposits (2) — 5,066 — 5,066 Foreign currency forward contract (3) — 610 — 610 Total financial assets $ 31,566 $ 250,343 $ — $ 281,909 Financial Liabilities: Foreign currency forward contract (4) — 1,165 — 1,165 Total financial liabilities $ — $ 1,165 $ — $ 1,165 December 31, 2022 Level I Level II Level III Total (In thousands) Financial Assets: Cash equivalents and investments (1) $ 39,198 $ 245,666 $ — $ 284,864 Restricted time deposit (2) — 185 — 185 Severance pay fund deposits (2) — 5,378 — 5,378 Foreign currency forward contract (3) — 726 — 726 Total financial assets $ 39,198 $ 251,955 $ — $ 291,153 Financial Liabilities: Foreign currency forward contract (4) — 1,463 — 1,463 Total financial liabilities $ — $ 1,463 $ — $ 1,463 _____________________ (1) Money market securities are valued using Level I of the fair value hierarchy, while the fair values of U.S. Treasuries, government bonds, commercial paper, corporate bonds and municipal bonds are considered Level II and are obtained from independent pricing services, which may use various methods, including quoted prices for identical or similar securities in active and inactive markets. See Note 4 for additional detail of the Company’s fixed income securities by balance sheet location. (2) Recorded within other assets. (3) Recorded within prepaid expenses and other current assets. (4) Recorded within accrued and other current liabilities. The Company records the fair values of the assets and liabilities relating to its undesignated foreign currency forward contracts on a gross basis in its condensed consolidated balance sheets, as they are not subject to master netting arrangements. There is no cash collateral required to be pledged by the Company or its counterparties. The Company enters into foreign currency forward exchange contracts to manage the effects of fluctuations in foreign currency exchange rates on its net cash flows from non-U.S. dollar denominated operations. By entering into foreign currency forward contracts, the Company is exposed to a potential credit risk that the counterparty to its contracts will fail to meet its contractual obligations. If a counterparty fails to perform, the Company’s maximum credit risk exposure would be the positive fair value of the foreign currency forward contracts, or any asset balance, which represents the amount the counterparty owes to the Company. In order to mitigate the counterparty risk, the Company performs an evaluation of its counterparty credit worthiness, and its forward contracts have a term of no more than 12 months. The Company had foreign currency forward contracts with Silicon Valley Bank (“SVB”), which was closed by the California regulators on March 10, 2023. On March 12, 2023, the Department of the Treasury, Federal Reserve and the FDIC approved actions enabling the FDIC to complete its resolution of SVB in a manner that fully protects all depositors and converted SVB to Silicon Valley Bridge Bank, N.A. On March 27, 2023, First-Citizens Bank & Trust Company (“First Citizens Bank”) entered into an agreement with the FDIC to acquire the Silicon Valley Bridge Bank, N.A and the Company’s existing foreign currency forward contracts were assumed by the First Citizens Bank. Therefore, the Company does not anticipate any nonperformance under its foreign currency forward contracts. During the three months ended March 31, 2023 and 2022, the Company recognized net losses of $0.1 million and $0.7 million, respectively, within interest income and other income (expense), net in its condensed consolidated statements of operations, related to mark-to-market adjustments on its undesignated foreign currency forward contracts. 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. The following table summarizes the carrying value and the estimated fair value of the Company’s Convertible Notes, based on Level II measurements of the fair value hierarchy: March 31, 2023 December 31, 2022 Carrying Value Estimated Fair Value Carrying Value Estimated Fair Value (In thousands) Convertible Notes $ 236,000 $ 180,446 $ 236,000 $ 180,752 See Note 15 for information regarding partial redemption of the Convertible Notes in April 2023.

Long Term Debt

Long Term Debt	3 Months Ended

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 the Notes due July 1, 2026 for $236.0 million aggregate principal amount of 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 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 of $25 per share of the Company’s common stock), subject to adjustment. The Company may not redeem the Convertible Notes prior 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 least 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 to 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 multiples of $1,000 principal 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. See Note 15 for information regarding partial redemption of the Convertible Notes in April 2023. Revolving Credit Facility On November 2, 2021, the Company entered into the Second Amended and Restated Loan and Security Agreement with 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.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s interim (benefit) provision from income taxes is determined based on its annual estimated effective tax rate, applied to the actual year-to-date income, and adjusted for the tax effects of any discrete items. The Company’s effective tax rates for the three months ended March 31, 2023 and 2022 were 23.4% and 34.3%, respectively. The Company’s effective tax rate for the three months ended March 31, 2023 was higher than the United States federal statutory tax rate of 21%, primarily due to certain non-deductible stock-based compensation expenses partially offset by a deduction related to foreign-derived intangible income. The Company’s effective tax rate for the three months ended March 31, 2022 was higher than the United States federal statutory tax rate of 21%, primarily due to the inclusion of foreign subsidiaries’ income in the U.S., as well as due to certain non-deductible stock-based compensation expenses. On August 16, 2022, the U.S. enacted the Inflation Reduction Act of 2022, which among other things implements a 15% minimum tax on adjusted financial statement income of certain large corporations and a 1% excise tax on net stock repurchases. Based on the Company’s current level of income and share repurchase program, this legislation is not expected to have a material impact on its consolidated financial statements. In addition, a provision enacted as part of the 2017 Tax Cuts & Jobs Act requires companies to capitalize certain research and experimental expenditures for tax purposes in tax years beginning after December 31, 2021. As a result, the Company expects to utilize a substantial portion of its federal net operating loss carryforwards in 2023.

Stockholders' Equity	Stockholders’ Equity Share Repurchases On December 14, 2022, the Company’s Board of Directors (the “Board”) approved a new share repurchase program, authorizing the Company to repurchase up to $30 million of its common stock, par value $0.001 per share, with no requirement to purchase any minimum number of shares. The manner, timing, and actual number of shares repurchased under the program will depend on a variety of factors, including price, general business and market conditions, and other investment opportunities. Shares may be repurchased through privately negotiated transactions or open market purchases, including through the use of trading plans intended to qualify under Rule 10b5-1 under the Exchange Act. The repurchase program may be commenced, suspended, or terminated at any time by the Company at its discretion without prior notice.

Stock-based Compensation	Stock-based Compensation Equity Incentive Plans In July 2021, the Board and the Company’s stockholders approved the 2021 Long-Term Incentive Plan (the “2021 LTIP”), which may be used to grant, among other award types, stock options and restricted stock units (“RSUs”). The number of shares of common stock reserved for future issuance under the 2021 Plan will also be increased pursuant to provisions for annual automatic evergreen increases. The Company’s previous awards issued under its 2007 Omnibus Securities and Incentive Plan, as amended and restated on January 21, 2009 (“2007 Plan”), remain subject to the 2007 Plan. As of March 31, 2023, approximatel y 8,595,000 and 453,000 sha res were available for grant under the 2021 LTIP and the 2007 Plan, respectively. The Company generally issues new shares for stock option exercises and vesting of restricted stock units. The Company recognizes stock-based compensation expense for stock-based awards, including stock options, RSUs and stock appreciation rights (“SARs”), based on the estimated fair value of the awards. The Company estimates the fair value of its stock option awards on the grant date using the Black-Scholes option pricing model. The fair value of RSUs is the fair value of the Company’s common stock on the date of grant. The Company accounts for forfeitures as they occur. The following table summarizes stock-based compensation expense recognized in the Company’s condensed consolidated statements of operations for the periods presented: Three Months Ended March 31, 2023 2022 (In thousands) Research and development $ 502 $ 537 Sales and marketing 1,026 1,173 General and administrative 1,083 1,023 Total stock-based compensation $ 2,611 $ 2,733 As of March 31, 2023, the Company’s remaining unrecognized stock-based compensation expense was $1.8 million for unvested stock options and $22.1 million for unvested RSUs.

Organization, Description of Business and Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2023
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	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, 2022, filed with the Securities and Exchange Commission on March 15, 2023 (“2022 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 credit losses, 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, valuation of 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.
Cash and Cash Equivalents, and Investments	Cash and Cash Equivalents and Investments The Company considers all highly liquid investments with maturities of three months or less when purchased to be cash equivalents. Cash and cash equivalents consist of cash on hand and highly liquid investments in money market funds, U.S. government bonds and commercial paper. Most of our cash deposits are above the $250,000 Federal Deposit Insurance Corporation (“FDIC”) limit and, therefore, not insured.
Restricted Cash	Restricted Cash Restricted cash represents security deposits for facility leases and is included in other assets in the accompanying condensed consolidated balance sheets.
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.
Segment Information	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 And Recently Issued 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 Issued Accounting Pronouncements The Company has considered all new accounting pronouncements and has concluded that based on the current information, there are no new pronouncements that are expected to have a material impact on its results of operations, financial condition, or cash flows.
Fair Value Measurement	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 contracts. 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
Derivative Financial Instruments	The Company records the fair values of the assets and liabilities relating to its undesignated foreign currency forward contracts on a gross basis in its condensed consolidated balance sheets, as they are not subject to master netting arrangements. There is no cash collateral required to be pledged by the Company or its counterparties. The Company enters into foreign currency forward exchange contracts to manage the effects of fluctuations in foreign currency exchange rates on its net cash flows from non-U.S. dollar denominated operations. By entering into foreign currency forward contracts, the Company is exposed to a potential credit risk that the counterparty to its contracts will fail to meet its contractual obligations. If a counterparty fails to perform, the Company’s maximum credit risk exposure would be the positive fair value of the foreign currency forward contracts, or any asset balance, which represents the amount the counterparty owes to the Company. In order to mitigate the counterparty risk, the Company performs an evaluation of its counterparty credit worthiness, and its forward contracts have a term of no more than 12 months. The Company had foreign currency forward contracts with Silicon Valley Bank (“SVB”), which was closed by the California regulators on March 10, 2023. On March 12, 2023, the Department of the Treasury, Federal Reserve and the FDIC approved actions enabling the FDIC to complete its resolution of SVB in a manner that fully protects all depositors and converted SVB to Silicon Valley Bridge Bank, N.A. On March 27, 2023, First-Citizens Bank & Trust Company (“First Citizens Bank”) entered into an agreement with the FDIC to acquire the Silicon Valley Bridge Bank, N.A and the Company’s existing foreign currency forward contracts were assumed by the First Citizens Bank. Therefore, the Company does not anticipate any nonperformance under its foreign currency forward contracts.
Lessee, Leases	LeasesThe 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 2032.
