Description of the Company and Basis of Presentation	Description of the Company and Basis of Presentation Description of the Company OneSpan helps organizations accelerate digital transformations by enabling secure, compliant, and easy customer agreements and transaction experiences. The Company is a global leader in providing high-assurance identity and authentication security as well as enterprise-grade electronic signature (e-signature) solutions for use cases ranging from simple transactions to workflows that are complex or require higher levels of security. The Company’s solutions help its clients ensure the integrity of the people and records associated with digital agreements, transactions, and interactions in industries including banking, financial services, healthcare, and professional services. The Company offers a portfolio of products and services across identity verification, authentication, virtual interactions and transactions, and secure digital storage. OneSpan has operations in Austria, Australia, Belgium, Canada, China, France, Japan, The Netherlands, Singapore, Switzerland, the United Arab Emirates, the United Kingdom (U.K), and the United States (U.S.). Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of OneSpan and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, they do not include all of the information and notes required by generally accepted accounting principles in the United States of America (“U.S. GAAP”) for complete financial statements and should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. In the opinion of management, the accompanying unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements, and include all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the results of the interim periods presented. Operating results for the three months ended March 31, 2023 are not necessarily indicative of the results to be expected for any future period or the entire fiscal year. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Business Transformation In May 2022, the Company announced a three-year strategic transformation plan that began on January 1, 2023. The Company expects this transformation plan will enable it to build on its strong solution portfolio and market position, enhance its enterprise go-to-market strategy, accelerate revenue growth, and drive efficiencies to support margin expansion and increased profitability. In conjunction with the strategic transformation plan and to enable a more efficient capital deployment model, effective with the quarter ended June 30, 2022, the Company began reporting under the following two lines of business, which are its reportable operating segments: Digital Agreements and Security Solutions. The Company plans to manage Digital Agreements for accelerated growth and market share gains and Security Solutions for cash flow given its more modest growth profile. For further information regarding the Company’s reportable segments, see Note 3, Segment Information. While the Company’s consolidated results will not be impacted, the Company has recast its segment information for the three months ended March 31, 2022 for comparable presentation. Estimates and Assumptions The preparation of 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 disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Foreign Currency Translation and Transactions The financial position and results of the operations of the majority of the Company’s foreign subsidiaries are measured using the local currency as the functional currency. Accordingly, assets and liabilities are translated into U.S. Dollars using current exchange rates as of the balance sheet date. Revenue and expenses are translated at average exchange rates prevailing during the year. Translation adjustments arising from differences in exchange rates are charged or credited to other comprehensive income (loss). Losses resulting from foreign currency transactions were $0.2 million and $0.4 million for the three months ended March 31, 2023 and 2022, respectively, and are included in "Other income (expense), net" in the condensed consolidated statements of operations.
