Fair Value Disclosures [Text Block]	NOTE 2. Fair Value of Financial Instruments Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. For certain of the Company’s financial instruments, including certain cash equivalents, accounts receivable, accounts payable and accrued liabilities, the carrying amounts approximate their fair values due to the relatively short maturity of these balances. The Company measures and reports certain cash equivalents, marketable securities, derivative foreign currency forward contracts at fair value in accordance with the provisions of the authoritative accounting guidance that addresses fair value measurements. This guidance establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. The hierarchy is broken down into three Level 1 Level 2 Level 3 The Company's financial instruments consist of assets and liabilities measured using Level 1 2 1 2 The following table sets forth by level within the fair value hierarchy the fair value of the Company's financial assets and liabilities measured at fair value on a recurring basis: March 31, 2023 Level 1 Level 2 Fair Value (in thousands) Money market funds $ 3,520 $ — $ 3,520 Commercial paper — 75,697 75,697 U.S. Treasury and government agencies — 84,793 84,793 Corporate bonds — 45,790 45,790 Asset-backed securities — 8,546 8,546 Foreign currency forward contracts — 199 199 Total assets $ 3,520 $ 215,025 $ 218,545 Foreign currency forward contracts $ — $ 3,121 $ 3,121 Total liabilities $ — $ 3,121 $ 3,121 December 31, 2022 Level 1 Level 2 Fair Value (in thousands) Money market funds $ 82,701 $ — $ 82,701 U.S. Treasury and government agencies — 156,662 156,662 Foreign government — 1,006 1,006 Corporate bonds — 63,910 63,910 Asset-backed securities — 15,027 15,027 Foreign currency forward contracts — 1,493 1,493 Total assets $ 82,701 $ 238,098 $ 320,799 Foreign currency forward contracts $ — $ 4,679 $ 4,679 Total liabilities $ — $ 4,679 $ 4,679 There were no 1, 2 3 three March 31, 2023 2022.

Income Tax Disclosure [Text Block]	NOTE 11. Income Taxes The Company's income tax provision for interim periods is determined using an estimate of its annual effective tax rate, adjusted for discrete items, if any, that arise during the period. Each quarter, the Company updates its estimate of the annual effective tax rate, and if the estimated annual effective tax rate changes, the Company makes a cumulative adjustment in such period. The Company's quarterly tax provision, and estimate of its annual effective tax rate, is subject to variation due to several factors, including variability in pre-tax income (or loss), the mix of jurisdictions to which such income relates, changes in how the Company does business, tax law developments and possible outcomes of audits. The Company's estimated effective tax rate for the year differs from the U.S. statutory rate of 21% The Company recorded an income tax provision of $8.3 million and $7.9 million for the three March 31, 2023 2022 , respectively, resulting in an effective tax rate of 22.1% and 23.8%, respectively. The increase in income tax provision for the three March 31, 2023 compared to the three March 31, 2022 was primarily due to an increase in pre-tax income and lower excess tax benefits arising from stock-based compensation, partially offset by lower net capitalization of research and development expenses compared to the same period in 2022. As of March 31, 2023 , the Company had unrecognized tax benefits of $10.7 million, of which $5.4 million, if recognized, would favorably impact the Company's effective tax rate. As of December 31, 2022 , the Company had unrecognized tax benefits of $10.5 million, of which $5.3 million, if recognized, would favorably impact the Company's effective tax rate.
