Notes to Financial Statements
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 Company's cash and cash equivalents, and marketable securities consist of the following: June 30, 2022 Unrealized Unrealized Amortized Cost Gains Losses Fair Value (in thousands) Cash and cash equivalents: Cash $ 84,920 $ — $ — $ 84,920 Money market funds 35,046 — — 35,046 Commercial paper 999 — — 999 Total 120,965 — — 120,965 Short-term marketable securities: Commercial paper 32,137 — (37 ) 32,100 Corporate bonds 38,525 3 (343 ) 38,185 Asset-backed securities 5 — — 5 U.S. Treasury and government agencies 228,376 — (1,545 ) 226,831 Foreign government 1,007 — (4 ) 1,003 Total 300,050 3 (1,929 ) 298,124 Long-term marketable securities: Corporate bonds 36,998 — (991 ) 36,007 Asset-backed securities 23,310 3 (170 ) 23,143 U.S. Treasury and government agencies 21,137 — (165 ) 20,972 Total 81,445 3 (1,326 ) 80,122 Total $ 502,460 $ 6 $ (3,255 ) $ 499,211 December 31, 2021 Unrealized Unrealized Amortized Cost Gains Losses Fair Value (in thousands) Cash and cash equivalents: Cash $ 61,220 $ — $ — $ 61,220 Money market funds 75,258 — — 75,258 Commercial paper 850 — — 850 Total 137,328 — — 137,328 Short-term marketable securities:(1) Commercial paper 18,046 — — 18,046 Corporate bonds 28,869 101 (7 ) 28,963 Asset-backed securities 3,952 — — 3,952 U.S. Treasury and government agencies 217,160 2 (163 ) 216,999 Total 268,027 103 (170 ) 267,960 Long-term marketable securities: Corporate bonds 57,762 160 (182 ) 57,740 Asset-backed securities 14,941 6 (36 ) 14,911 U.S. Treasury and government agencies 37,664 — (136 ) 37,528 Foreign government 1,007 12 — 1,019 Total 111,374 178 (354 ) 111,198 Total $ 516,729 $ 281 $ (524 ) $ 516,486 ( 1 2 10 December 31, 2021.

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 $5.5 million and $8.7 million for the three June 30, 2022 2021 , respectively, resulting in an effective tax rate of 17.2% and 29.2%, respectively.

The Company recorded an income tax provision of $13.5 million and $6.3 million for the six June 30, 2022 2021 , respectively, resulting in an effective tax rate of 20.6% and 22.7%, respectively.
