Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On July 16, 2021, the Company declared a special dividend to its Parent of $13,046 with cash on hand which will be used to pay certain pre-IPO owners for their interests in lieu of their participation in the tax receivable agreement as further discussed below. Approximately $2,754 of the cash payments to pre-IPO owners are subject to vesting requirements and will be held in escrow. The cash payments held in escrow will be expensed over the requisite vesting period. The remaining $10,292 of the cash payments were paid and expensed in conjunction with the closing of the IPO. On July 16, 2021, the Company adopted the 2021 Equity Incentive Plan in order to provide a means through which to attract, retain and motivate key personnel. Awards available for grant under the 2021 Equity Incentive Plan include non-qualified and incentive stock options, restricted shares of our common stock, other equity based awards tied to the value of our common stock and cash-based awards. In conjunction with the IPO, the Company issued 1,659 restricted shares of common stock to convert all outstanding and unvested incentive units under the 2017 Incentive Plan. These restricted shares are subject to similar vesting terms and conditions that applied to the incentive units under the 2017 Incentive Plan prior to the conversion. Additionally, the Company issued 5,399 stock options to holders of incentive units under the 2017 Incentive Plan. The stock options allow the recipient to purchase common stock of the Company following the IPO at a strike price of $18.00 and have similar vesting terms and conditions that applied to the incentive units under the 2017 Incentive Plan. As a result of issuance of the stock options, the Company expects to record share-based compensation expense in conjunction with the IPO based on the grant-date fair value of the awards. On July 29, 2021, the Company executed a tax receivable agreement (the “TRA”) with certain pre-IPO owners (the “TRA Participants”) that provides for payment by the Company to the TRA Participants of 85% of the amount of cash savings, if any, in U.S. federal, state and local income tax that the Company expects to be able to utilize in the future from net operating losses and certain other tax benefits that arose prior to the IPO. The Company will record an estimated liability of approximately $112,681 representing the probable and reasonably estimable amount of its obligation over the term of the TRA with a corresponding charge to additional paid in capital as of July 29, 2021. In July 2021, the Company further amended its amended and restated certificate of incorporation which, among other things, effected a 150-for-1 stock split of its shares of common stock, increased the par value of its common stock from $0.001 to $0.01 per share, increased the authorized number of shares of its common stock to 500,000 and authorized 50,000 shares of preferred stock. All references to share and per share amounts in the Company’s condensed consolidated financial statements have been retrospectively revised to reflect the stock split, the increase in par value and the increase in authorized shares. On July 30, 2021 the Company completed its IPO. For details of this event, see Note 1. On August 4, 2021, the Company used a portion of the net proceeds from the IPO to repay a portion of the Incremental Term Loan outstanding under the Credit Agreement totaling $215,874, plus accrued interest of $1,028. The Company will incur a charge of $6,645 related to the write-off of unamortized debt issuance costs. On August 18, 2021, the Company closed the underwriters exercise of their over-allotment option to purchase 1,171 additional shares of our common stock from the Company, resulting in additional net proceeds of approximately $19,757 after deducting underwriting discounts and commissions of $1,317.
