Subsequent Events	Note 24. Subsequent Events Amended and Restated Credit Agreement On February 12, 2021, the Company entered into an amended and restated credit agreement (the “A&R Credit Agreement”). The A&R Credit Agreement provides for (i) a seven-year senior secured term B loan facility in an aggregate principal amount of $950 million (the “A&R Term B Facility”) and (ii) a five-year senior secured revolving credit facility in an aggregate principal amount of $500 million (the “A&R Revolving Credit Facility” and, together with the Term Loan Facilities, the “A&R Senior Credit Facilities”). The Company is obligated to make quarterly principal payments of approximately $2.4 million throughout the term of the A&R Term B Facility according to the amortization provisions in the A&R Credit Agreement. In addition to paying interest on outstanding borrowings under the A&R Revolving Credit Facility, the Company is required to pay a quarterly commitment fee based on the unused portion of the A&R Revolving Credit Facility. Borrowings under the A&R Credit Agreement can be prepaid at the Company’s option without premium or penalty other than a 1.00% prepayment premium that may be payable in connection with certain repricing transactions within a certain period of time after the closing date. Up to $75 million may be utilized under the A&R Revolving Credit Facility for the issuance of letters of credit to the Company or any of the Company’s subsidiaries. Letters of credit are available for issuance under the A&R Credit Agreement on terms and conditions customary for financings of this kind, which issuances will reduce the available funds under the A&R Revolving Credit Facility. The A&R Senior Credit Facilities are subject to an interest rate and interest period which the Company will elect. If the Company chooses to make a base rate borrowing on an overnight basis, the interest rate will be based on the highest of (1) the rate of interest last quoted by The Wall Street Journal as the “prime rate” in the United States, (2) the greater of the federal funds effective rate and the overnight bank funding rate, plus 0.5% and (3) the one month adjusted LIBOR rate, plus 1.00% per annum. For the A&R Term Loan B, the applicable LIBOR rate will not be less than 0.50% per annum. The applicable margin for the A&R Term B Facility is 2.25% per annum (for LIBOR loans) and 1.25% per annum (for base rate loans). The applicable margin for the A&R Revolving Credit Facility varies from 2.25% per annum to 1.75% per annum (for LIBOR loans) and 1.25% to 0.75% per annum (for base rate loans) based on the Company’s leverage ratio. Accordingly, the interest rates for A&R the Senior Credit Facilities will fluctuate during the term of the A&R Credit Agreement based on changes in the base rate, LIBOR rate or future changes in the Company’s leverage ratio. Interest payments with respect to the borrowings are required either on a quarterly basis (for base rate loans) or at the end of each interest period (for LIBOR loans) or, if the duration of the applicable interest period exceeds three months, then every three months. The A&R Credit Agreement contains certain affirmative and negative covenants customary for financings of this type that, among other things, limit the Company and the Company’s subsidiaries’ ability to incur additional indebtedness or liens, to dispose of assets, to make certain fundamental changes, enter into restrictive agreements, to make certain investments, loans, advances, guarantees and acquisitions, to prepay certain indebtedness and to pay dividends, to make other distributions or redemptions/repurchases, in respect of the Company and the Company’s subsidiaries’ equity interests, to engage in transactions with affiliates or amend certain material documents. In addition, the A&R Revolving Credit Facility also contains certain financial maintenance covenants. The A&R Credit Agreement contains customary events of default, including with respect to a failure to make payments under the A&R Senior Credit Facilities, cross-default, certain bankruptcy and insolvency events and customary change of control events. All obligations under the A&R Senior Credit Facilities are or will be unconditionally guaranteed jointly and severally, by: (a) the Company and (b) substantially all of the direct and indirect wholly owned subsidiaries of the Company that are organized under the laws of the United States, any state thereof or the District of Columbia (collectively, the “Guarantors”). The Guarantors entered into a guarantee under the A&R Credit Agreement concurrently with the effectiveness of the A&R Credit Agreement. Subject to certain limitations, the A&R Senior Credit Facilities are or will be secured on a first priority basis by: (x) a perfected security interest in the equity interests of each direct subsidiary of the Company and each Guarantor under the A&R Senior Credit Facilities (subject to certain customary exceptions) and (y) perfected, security interests in, and mortgages on, substantially all tangible and intangible personal property and material real property of the Company and each of the Guarantors under the A&R Senior Credit Facilities, subject, in each case, to certain exceptions. The Company and the Guarantors entered into security documents concurrently with effectiveness of the A&R Credit Agreement. Senior Notes On February 16, 2021 the Company redeemed $140 million in principal amount of the Senior Notes at a redemption price of 106.125% of par plus accrued interest. Amendment to Reimbursement Agreement On February 12, 2021, in connection with entering into the A&R Credit Agreement, the Company entered into a Fourth Amendment to the Reimbursement Agreement.
