These accompanying unaudited interim Consolidated Financial Statements (“Consolidated Financial Statements”) have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial statements. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC.

The unaudited results of operations for the three and nine months ended September 30, 2021 are not necessarily indicative of results that may be expected for the year ending December 31, 2021. Use of Estimates. The preparation of the accompanying Consolidated Financial Statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect amounts reported in the Consolidated Financial Statements and accompanying disclosures. Although these estimates are based on management’s best knowledge of current events and actions that the Company may undertake in the future, actual results may differ from those estimates.

Interest Rate Swap

Interest Rate Swap	9 Months Ended
	Sep. 30, 2021
Derivative Instruments and Hedging Activities Disclosure [Abstract]
Interest Rate Swap	NOTE 5. Interest Rate Swap The interest rate on borrowings under the Company’s Term Loan is floating and, therefore, subject to fluctuations. In order to manage the risk associated with changes in interest rates on its borrowing under the initial Term Loan, the Company entered into an interest rate swap (the “Swap”) effective December 31, 2018. Under the terms of the Swap, the Company is locked into a fixed rate of interest of 2.96 % plus an applicable margin, as defined in the Company’s Credit Agreement, on a notional amount of $ 300 million until May 31, 2022. The Swap was initially designated as a cash flow hedge of interest rate risk. During the second quarter of 2020, the Company entered into the second amendment to the Credit Agreement, which triggered a quantitative hedge effectiveness test that resulted in the loss of hedge accounting. As a result, as of the date of the second amendment, the unrealized loss included within Accumulated other comprehensive loss was frozen and is now being ratably reclassified into Net income (loss) over the remaining life of the Swap through Interest expense, net and Income tax expense (benefit) within the Consolidated Statements of Income (Loss). Subsequent to the second amendment, any changes in the fair value of the Swap are recorded within Other income (expense), net on the Consolidated Statements of Income (Loss). During the fourth quarter of 2020, the Company entered into the third amendment to the Credit Agreement, which triggered a partial debt extinguishment, including a partial extinguishment of the underlying Term Loan. Due to the reduction in the Term Loan as compared to the notional amount of the Swap, the Company wrote-off a proportional amount of the frozen Accumulated other comprehensive loss balance as of the date of the partial extinguishment proportional to the reduction in the underlying notional amount of Term Loan. The Company will continue to amortize the remaining Accumulated other comprehensive loss to Interest expense, net and Income tax expense (benefit) within the Consolidated Statements of Income (Loss) through the remainder of the term of the Swap. Any changes in the fair value of the Swap will continue to be recorded within Other income (expense), net on the Consolidated Statements of Income (Loss). As of September 30, 2021, the fair value of the Swap was an unrealized loss of $ 5.8 million, which is recorded in Other accrued liabilities on the Consolidated Balance Sheets. As of December 31, 2020, the fair value of the Swap was an unrealized loss of $ 12.1 million, of which $ 8.5 million and $ 3.6 million was recorded in Other accrued liabilities and Other noncurrent liabilities, respectively, on the Consolidated Balance Sheets. During the nine months ended September 30, 2021 and 2020, $ 4.3 million and $ 2.5 million was reclassified from Accumulated other comprehensive loss and recorded in Interest expense, net, respectively. During the nine months ended September 30, 2021, the Company made payments of $ 6.4 million related to the Swap and $ 0.7 million was reclassified as a tax benefit from Accumulated other comprehensive loss into Income tax expense (benefit) on the Consolidated Statements of Income (Loss).

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 6. Commitments and Contingencies The Company and its subsidiaries are parties from time to time in legal and administrative proceedings involving matters incidental to its business. These matters, whether pending, threatened or unasserted, if decided adversely to the Company or settled, may result in liabilities material to its financial position, results of operations or cash flows. The Company records a liability when it believes that it is both probable that a loss will be incurred and the amount of loss can be reasonably estimated. The Company evaluates, at least quarterly, developments in its legal matters that could affect the amount of liability that has been previously accrued and makes adjustments as appropriate. Significant judgment is required to determine both the probability and the estimated amount.

Earnings Per Share [Abstract]
Earnings (Loss) Per Share	NOTE 8. Earnings (Loss) Per Share Basic earnings (loss) per share is calculated by dividing Net income (loss) by the weighted-average number of shares of common stock outstanding. Diluted earnings (loss) per share is similarly calculated, except that the calculation includes the dilutive effect of the assumed issuance of shares under stock-based compensation plans, unless the inclusion of such shares would have an anti-dilutive effect. The computation of Earnings (loss) per share is as follows (in thousands, except per share data): Three Months Ended September 30, Nine Months Ended September 30, 2021 2020 2021 2020 Net income (loss) $ 2,431 $ ( 12,261 ) $ 13,675 $ ( 824,339 ) Basic weighted-average common shares outstanding 69,067 67,295 68,576 67,163 Effect of dilutive stock-based compensation awards (1) 1,878 — 2,489 — Diluted weighted-average common shares outstanding 70,945 67,295 71,065 67,163 Earnings (loss) per share, basic $ 0.04 $ ( 0.18 ) $ 0.20 $ ( 12.27 ) Earnings (loss) per share, diluted 0.03 ( 0.18 ) 0.19 ( 12.27 ) (1) There were 1,369 and 2,776 potential common shares excluded from diluted weighted-average common shares outstanding for the three months ended September 30, 2021 and September 30, 2020, respectively, and 1,376 and 2,195 potential common shares for the nine months ended September 30, 2021 and September 30, 2020, respectively, as their inclusion would have had an anti-dilutive effect.

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 10. Income Taxes Deferred Tax Asset and Valuation Allowance. Due to the goodwill and indefinite-lived intangible asset impairments recorded during the year ended December 31, 2020, the Company has concluded a valuation allowance is required against its deferred tax assets as of September 30, 2021. In reaching this conclusion, in accordance with U.S. GAAP, the Company has evaluated all available evidence, both positive and negative and determined that the Company’s history of recent losses was sufficient significant negative evidence to require a valuation allowance. Therefore, the Company has recorded a valuation allowance to reduce its deferred tax assets as of September 30, 2021 to the amount that is more likely than not to be realized in future periods. At each reporting date, management considers new evidence, both positive and negative, that could affect its view of the future realization of deferred tax assets. Tax Refund. During the nine months ended September 30, 2021, the Company received a $ 9.1 million tax refund related to the carryback of federal and state income tax net operating loss as a result of the CARES Act. Effective Tax Rate. The effective income tax rate, expressed by calculating the income tax expense as a percentage of Income before income tax, was 8.4 % for the nine months ended September 30, 2021, which varied from the statutory federal income tax rate of 21 %, primarily due to the tax benefit realized on stock-based compensation, partially offset by the valuation allowance on the Company’s net deferred tax asset position recorded during the nine months ended September 30, 2021. The effective income tax rate was 12.0 % for the nine months ended September 30, 2020, which differed from the statutory federal income tax rate of 21 %, primarily due to the tax impact of the goodwill and intangible asset impairments and the valuation allowance recorded during the nine months ended September 30, 2020.
