​ Credit Agreement ​ On February 8, 2021, the Company entered into the 2021 Refinancing Amendment to Credit Agreement (as amended, modified or otherwise supplemented, the “Credit Agreement”), pursuant to which the Company amended and restated its Syndicated Facility Agreement, dated as of October 17, 2014 (as amended prior to February 8, 2021, the “Original Credit Agreement”), between the Company, as borrower, Bank of America, N.A., as administrative agent, and other parties thereto. At the time of amendment, the Credit Agreement consisted of a $1,150,000,000 revolving credit facility (the “Original Revolving Credit Facility”) and a $246,968,737.50 term loan A facility (the “Original Term A Facility,”), each of which would have matured on February 8, 2026. The proceeds of the Original Revolving Credit Facility and the Original Term A Loan facility borrowed on February 8, 2021 were used to refinance the existing revolving credit facility and the existing term loan facility under the Original Credit Agreement and to pay related fees and expenses. ​ On April 13, 2021, the Company entered into Amendment No. 10 to Credit Agreement, pursuant to which the lenders thereunder provided a secured term B credit facility (the “Original Term B Facility,” and together with the Original Term A Facility and Original Revolving Credit Facility, the “Original Credit Facilities”) to the Company in an aggregate principal amount of $700,000,000. The Original Term B Facility would have matured on April 13, 2028. The proceeds of the Original Term B Facility were used to fund the purchase price, fees and expenses in connection with the Company’s cash tender offer to purchase up to $700,000,000 aggregate purchase price (not including any accrued and unpaid interest) of its outstanding 5.875% Senior Notes due 2024. ​ On June 25, 2021, the Company entered into Amendment No. 11 to Credit Agreement, pursuant to which lenders thereunder provided the Company an additional $215,000,000 in aggregate principal amount under the Original Term A Facility. The Company used the net proceeds from the increase in the Original Term A Facility (together with cash on hand), to (i) redeem all of the Company’s remaining 5.875% Senior Notes due 2024 and (ii) pay fees and expenses related to such redemption. ​ On May 23, 2023, the Company entered into Amendment No. 12 to Credit Agreement, pursuant to which LIBOR as a benchmark rate of interest was replaced by, in the case of U.S. dollar-denominated loans, a secured overnight financing rate subject to a spread adjustment, and, in the case of loans denominated in other currencies, other customary successor rates, subject in certain cases to a spread adjustment. On May 23, 2023, the Company entered into Amendment No. 13 to Credit Agreement, pursuant to which the spread adjustments with respect to the Original Revolving Credit Facility and the Original Term A Facility were amended. ​ On April 19, 2024, the Company entered into Amendment No. 14 to Syndicated Facility Agreement, pursuant to which the Company obtained a new $1,500,000,000 revolving credit facility (the “New Revolving Credit Facility”), a new $750,000,000 term loan A facility (the “New Term A Facility” and, together with the New Revolving Credit Facility, the “New Pro Rata Facilities”) and a new $700,000,000 term loan B facility (the “New Term B Facility” and, together with the New Pro Rata Facilities, the “New Credit Facilities”). The New Revolving Credit Facility and the New Term A Facility mature on April 19, 2029. The New Term B Facility matures on April 19, 2031. The New Term A Facility and the New Term B Facility were borrowed in full on April 19, 2024 in U.S. dollars. Loans under the New Revolving Credit Facility may be borrowed, and letters of credit thereunder may be issued, in U.S. dollars or in certain foreign currencies. The New Credit Facilities replace in full the Original Revolving Credit Facility, the Original Term A Facility and the Original Term B Facility, and borrowings under the New Credit Facilities were used to refinance in full the Original Credit Facilities and for general corporate purposes. The Credit Agreement permits the Company to designate certain of its subsidiaries as additional co-borrowers from time to time. Currently, there are no co-borrowers under the New Credit Facilities. ​ Borrowings under (a) the New Revolving Credit Facility (in U.S. dollars) and the New Term A Facility will bear interest at a rate per annum equal to, at the Company’s option, (i) a Term SOFR rate (with a 0% floor and SOFR adjustment of 0.10%) or (ii) a base rate (with a 0% floor), in each case, plus an applicable margin of 1.25% in the case of the Term SOFR rate and 0.25% in the case of the base rate, and (b) the New Revolving Credit Facility in currencies other U.S. dollars will bear interest at a rate per annum equal to the applicable reference rate for such currency (including any related adjustments), plus an applicable margin of 1.25%. The applicable margin is subject, in each case, to adjustment based on the Company’s consolidated leverage ratio from time to time. ​ Borrowings under the New Term B Facility will bear interest at a rate per annum equal to, at the Company’s option, (a) a Term SOFR rate (with a 0% floor and a SOFR adjustment of 0%) or (b) a base rate (with a 0% floor), in each case, plus an applicable margin of 1.875% in the case of the Term SOFR rate and 0.875% in the case of the base rate. ​ Certain of the Company’s material subsidiaries (the “Guarantors”) have guaranteed the Company’s obligations of the borrowers under the Credit Agreement, subject to certain exceptions. The borrowers’ obligations under the Credit Agreement are secured by a lien on substantially all of the Company’s assets and its Guarantors’ assets, subject to certain exceptions. ​ The Credit Agreement contains customary negative covenants that include, among other things, limitations on the ability of the Company and certain of its subsidiaries, subject to certain exceptions, to incur liens and debt, make investments, dispositions, and restricted payments, change the nature of their business, consummate mergers, consolidations and the sale of all or substantially all of their respective assets and transact with affiliates. The Company is also required to maintain a consolidated leverage ratio of less than or equal to 4.00 to 1.00 (subject to certain adjustments in connection with permitted acquisitions), tested on a quarterly basis (the “Financial Covenants”). The Financial Covenants do not apply to the New Term B Facility. As of March 31, 2024, the Company was in compliance with the covenants of the Credit Agreement. ​ The Credit Agreement contains customary affirmative covenants, including, among other things, compliance with applicable law, preservation of existence, maintenance of properties and of insurance, and keeping proper books and records. The Credit Agreement contains customary events of default, including, among other things, nonpayment of principal, interest or fees, cross-defaults to other debt, inaccuracies of representations and warranties, failure to perform covenants, events of bankruptcy and insolvency, change of control and unsatisfied judgments, subject in certain cases to notice and cure periods and other exceptions. ​ At March 31, 2024 and September 30, 2023, letters of credit totaled $4.4 million and $4.4 million, respectively, under the Company’s Original Revolving Credit Facility. As of March 31, 2024 and September 30, 2023, the Company had $1,145.6 million and $1,145.6 million, respectively, available under its Original Revolving Credit Facility. ​ 2027 Senior Notes ​ On February 21, 2017, the Company completed a private placement offering of $1,000,000,000 aggregate principal amount of its unsecured 5.125% Senior Notes due 2027 (the “2027 Senior Notes”). On June 30, 2017, the Company completed an exchange offer to exchange the unregistered 2027 Senior Notes for registered notes, as well as related guarantees. ​ As of March 31, 2024, the estimated fair value of the 2027 Senior Notes was approximately $977.3 million. The fair value of the 2027 Senior Notes as of March 31, 2024 was derived by taking the mid-point of the trading prices from an observable market input (Level 2) in the secondary bond market and multiplying it by the outstanding balance of the 2027 Senior Notes. Interest is payable on the 2027 Senior Notes at a rate of 5.125% per annum. Interest on the 2027 Senior Notes is payable semi-annually on March 15 and September 15 of each year, commencing on September 15, 2017. The 2027 Senior Notes will mature on March 15, 2027. ​ At any time and from time to time prior to December 15, 2026, the Company may redeem all or part of the 2027 Senior Notes, at a redemption price equal to 100% of their principal amount, plus a “make whole” premium as of the redemption date, and accrued and unpaid interest to the redemption date. On or after December 15, 2026, the Company may redeem all or part of the 2027 Senior Notes at a redemption price equal to 100% of their principal amount, plus accrued and unpaid interest on the redemption date. ​ The indenture pursuant to which the 2027 Senior Notes were issued contains customary events of default, including, among other things, payment default, exchange default, failure to provide notices thereunder and provisions related to bankruptcy events. The indenture also contains customary negative covenants. ​ The Company was in compliance with the covenants relating to the 2027 Senior Notes as of March 31, 2024. ​ Other Debt and Other Items ​ Other debt consists primarily of obligations under capital leases and loans, and unsecured credit facilities. The Company’s unsecured credit facilities are primarily used for standby letters of credit issued in connection with general and professional liability insurance programs and for contract performance guarantees. At March 31, 2024 and September 30, 2023, these outstanding standby letters of credit totaled $895.3 million and $878.9 million, respectively. As of March 31, 2024, the Company had $418.9 million available under these unsecured credit facilities. ​ Effective Interest Rate ​ The Company’s average effective interest rate on its total debt, including the effects of the interest rate swap and interest rate cap agreements, during the six months ended March 31, 2024 and 2023 was 5.5% and 5.2%, respectively. ​ Interest expense in the consolidated statements of operations included amortization of deferred debt issuance costs for the three and six months ended March 31, 2024 of $1.2 million and $2.4 million, respectively, and for the three and six months ended March 31, 2023 of $1.2 million and $2.4 million, respectively.
