Accounting Policies [Abstract]
Summary of Significant Accounting Policies	N ote 2. Summary of Significant Accounting Policies The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial statements and pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of only normal recurring adjustments, considered necessary for fair presentation have been included. The results of operations for the three and six months ended June 30, 2021 are not necessarily indicative of the results to be expected for the year ended December 31, 2021 or any future period. The accompanying unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto for the year ended December 31, 2020 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. Risks and Uncertainties The COVID-19 pandemic continues to rapidly evolve and has adversely impacted global commercial activities. Management expects COVID-19 related changes in market and investor behaviors to impact our asset- and spread-based revenue. However, given the uncertainty around the duration and extent of the COVID - 19 pandemic, management cannot predict the impact on the Company’s results of operations, financial condition or liquidity in the third quarter for 202 1 and subsequent periods . Estimates and assumptions about future events and their effects on the Company cannot be determined with certainty and therefore require the exercise of judgment. The Company is not aware of any specific events or circumstances that would require the Company to update its estimates, assumptions or judgments or revise the carrying value of its assets or liabilities. The Company will update the estimates and assumptions underlying the consolidated financial statements in future periods as events and circumstances develop. Recent Accounting Pronouncements – Adopted In December 2019, the Financial Accounting Standards Board (the “FASB”) issued ASU 2019-12, Income Taxes (Topic 740), Simplifying the Accounting for Income Taxes, which removes certain exceptions to the general principles in Topic 740 and improves consistent application of U.S. GAAP by clarifying and amending existing guidance. The Company adopted the new standard on January 1, 2021, and it did not have a significant impact on the Company’s consolidated financial statements and related disclosures. Recent Accounting Pronouncements – Not Yet Adopted In April 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848), Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides companies with optional guidance to ease the accounting impact of contract modification in connection with changes in reference rates. The ASU is available for adoption through December 31, 2022. The Company is evaluating the impact that ASU 2020-04 will have on its consolidated financial statements.

Debt	Note 10 . Debt On November 14, 2018, the Company executed a Credit Agreement (the “Prior Credit Agreement”) with Credit Suisse AG for a $250,000 term loan (the “Term Loan”) and a revolving line of credit (the “Revolver”) that permitted the Company to borrow up to $20,000. The Term Loan was set to mature on November 14, 2025 and the Revolver was set to mature on November 14, 2023. On July 26, 2019, the Company made a partial repayment of $125 million of the Company’s outstanding indebtedness under the Term Loan and repaid the remaining outstanding amount on December 30, 2020 through the execution of the New Credit Agreement (as defined below). On December 30, 2020, the Company entered into a Credit Agreement (the “New Credit Agreement”) with the Bank of Montreal for a new senior secured credit facility in an aggregate principal amount of $250,000, consisting of a revolving credit facility with commitments in an aggregate principal amount of $250,000 (the “New Revolving Credit Facility” and the loans thereunder, the “New Revolving Loans”), with an accordion option of up to $25,000. The Company drew down $75,000 under the New Revolving Credit Facility on December 30, 2020, with an annual interest rate of 2.25%, the proceeds of which, together with cash on hand, were used to repay in full the Company’s obligations under the Term Loan. In connection with such repayment in full, the Prior Credit Agreement, the commitments thereunder and the guarantees and security interests with respect thereto were terminated and released, as applicable. The remaining portion of the New Revolving Credit Facility is available to finance the working capital needs and for other general corporate purposes of the Company (including acquisitions, investments, dividends and share repurchases permitted under the New Credit Agreement). On June 22, 2021, the Company drew down $75,000 under the New Revolving Credit Facility. See Note 17 for additional information regarding partial repayment subsequent to June 30, 2021. The New Revolving Loans bear interest at a rate per annum equal to, at the Company’s option, either (i) LIBOR plus a margin based on the Company’s Total Leverage Ratio (as defined in the New Credit Agreement) or (ii) the Base Rate (as defined in the New Credit Agreement) plus a margin based on the Company’s Total Leverage Ratio. The margin will range between 1.00% and 2.625% for base rate loans and between 2.00% and 3.625% for LIBOR loans. The Company will pay a commitment fee based on the average daily unused portion of the commitments under the New Revolving Credit Facility, a letter of credit fee equal to the margin then in effect with respect to the LIBOR loans under the New Revolving Credit Facility, a fronting fee and any customary documentary and processing charges for any letter of credit issued under the New Credit Agreement. The New Revolving Credit Facility is not subject to amortization and will mature on December 30, 2024.

The Company’s effective tax rate was 50.3% and (167.1)% for the three months ended June 30, 2021 and 2020, respectively, and 64.9% and (292.3)% for the six months ended June 30, 2021 and 2020, respectively. These changes were primarily due to changes in the relative amounts of the Company’s share-based compensation and income before taxes On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act was signed into law. The provisions of the CARES Act affecting corporations include, but are not limited to, elimination of certain limitations for utilizing net operating losses, relaxation of limitations on interest deductions, the expensing of costs of acquired qualified improvement property, employee retention tax credits and deferral of payroll taxes.

Earnings Per Share [Abstract]
Net Income (Loss) Per Share Attributable to Common Stockholders	Note 16. Net Income (Loss) Per Share Attributable to Common Stockholders Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding for the period. For the calculation of diluted net income per share, the basic weighted average number of shares of common stock outstanding is increased by the dilutive effect (if any) of stock options, restricted stock awards, restricted stock units and stock appreciation rights. The following table provides a reconciliation of the numerators and denominators used in computing basic and diluted net income (loss) per share attributable to common stockholders: Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 Net income (loss) attributable to common stockholders $ 9,986 $ (9,280 ) $ 1,070 $ (6,544 ) Weighted average number of shares of common stock used in computing net income (loss) per share attributable to common stockholders, basic 71,922,179 67,208,746 71,176,386 67,175,603 Net income (loss) per share attributable to common stockholders, basic $ 0.14 $ (0.14 ) $ 0.02 $ (0.10 ) Weighted average shares used in computing net income (loss) per share attributable to common stockholders, basic 71,922,179 67,208,746 71,176,386 67,175,603 Effect of dilutive shares: Unvested RSAs 136,903 — — — Unvested RSUs 95,986 — 54,951 — Diluted number of weighted-average shares outstanding 72,155,068 67,208,746 71,231,337 67,175,603 Net income (loss) per share attributable to common stockholders, diluted $ 0.14 $ (0.14 ) $ 0.02 $ (0.10 ) The following securities were not included in the computation of diluted shares because such securities did not have a dilutive effect.
