Income Taxes	6 Months Ended
Income Taxes	Jun. 30, 2023
Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesIncome taxes are determined using an estimated annual effective tax rate applied against income, and then adjusted for the tax impacts of certain significant and discrete items. For the six months ended June 30, 2023, the Company treated the tax impact of the following as discrete events for which the tax effect was recognized separately from the application of the annual effective tax rate: tax expense related to shortfalls on stock-based compensation and tax reserves. The Company’s effective tax rate recorded for the six months ended June 30, 2023 was 50%, primarily due to the size of discrete items of tax expense related to shortfalls on stock-based compensation and tax reserves relative to year-to-date pretax income. In accordance with the disclosure requirements as described in Accounting Standards Codification 740, Income Taxes, the Company has classified unrecognized tax benefits as non-current income tax liabilities, or a reduction in deferred tax assets, unless expected to be paid within one year. The Company’s continuing practice is to recognize interest and/or penalties related to income tax matters in income tax expense. During the six months ended June 30, 2023, there was an increase in gross unrecognized tax benefits of approximately $3.6 million, primarily related to research and development credits and the valuation of intangible assets. The Company believes it is reasonably possible that approximately $1.4 million of its remaining unrecognized tax positions may be recognized within the next twelve months primarily attributable to a settlement with the Dutch tax authority related to tax positions involving the valuation of intercompany transactions. The Company is subject to routine compliance reviews on various tax matters around the world in the ordinary course of business. Currently, the only active audits are with the U.S. Internal Revenue Service for the 2014 – 2016 tax years, Illinois State for the 2020 tax year, the Netherlands for the 2019 tax year, and Italy for the 2017 tax year. California income tax returns are subject to examination in all years due to prior year net operating losses and research and development credits. Income tax returns of other major state and foreign jurisdictions remain subject to examination from 2018 and 2017 forward, respectively.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
