Reclassification

Certain items in the prior years’ condensed consolidated financial statements have been reclassified to conform to the current year presentation reflected in the condensed consolidated financial statements.

Basis of Presentation

The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and pursuant to the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). The Company has condensed or omitted certain information and notes normally included in complete annual financial statements prepared in accordance with GAAP. These unaudited interim condensed consolidated financial statements should therefore be read in conjunction with the audited condensed consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K filed with the SEC on February 25, 2022 (the “Annual Report”). In the opinion of management, all material adjustments, which are of a normal and recurring nature, necessary for a fair statement of the results for the periods presented have been reflected in the condensed consolidated financial statements. The results of operations of any interim period are not necessarily indicative of the results of operations for the full annual period or any future period due to seasonal and other factors.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with GAAP requires the Company to make estimates and judgments that affect the amounts reported and disclosed in the condensed consolidated financial statements and accompanying notes. Actual results could differ from these estimates and judgments. The accounting estimates that require management’s most subjective judgments include: stock-based compensation; income taxes, including the estimate of the annual effective tax rate at interim periods and evaluation of uncertain tax positions; the valuation of acquired intangible assets, developed technology, and goodwill as part of purchase price allocations for business combinations; valuation of goodwill; and leases.
