​ Unsecured revolving credit facility: The Company is party to a credit agreement dated June 15, 2021, as amended as of March 6, 2023 (the “Credit Agreement”). The Credit Agreement provides for a five-year $1.8 billion unsecured revolving credit facility (the “Revolving Credit Facility”) arranged by JPMorgan Chase Bank, N.A., which is scheduled to mature in June of 2026. The Credit Agreement includes a $200 million sub-limit for the issuance of letters of credit and a $75 million sub-limit for swing line borrowings under the Revolving Credit Facility. As described in the Credit Agreement governing the Revolving Credit Facility, the Company may, from time to time, subject to certain conditions, increase the aggregate commitments under the Revolving Credit Facility by up to $900 million, provided that the aggregate amount of the commitments does not exceed $2.7 billion at any time. ​ On March 6, 2023, the Company entered into the First Amendment (the “Amendment”) to the credit agreement to convert the LIBOR based pricing to Secured Overnight Financing Rate (“SOFR”) based pricing. The Amendment replaces an Adjusted LIBO Rate with an Adjusted Term SOFR Rate, comprised of the Term SOFR Rate plus 0.100%. The Amendment made no other material changes to the terms of the credit agreement. ​ As of December 31, 2023 and 2022, the Company had outstanding letters of credit, primarily to support obligations related to workers’ compensation, general liability and other insurance policies, under the Credit Agreement in the amounts of $5.4 million and $5.1 million, respectively, reducing the aggregate availability under the Credit Agreement by those amounts. Substantially all of the outstanding letters of credit have a one-year term from the date of issuance. As of December 31, 2023 and 2022, the Company had no outstanding borrowings under its Revolving Credit Facility. ​ Borrowings under the Revolving Credit Facility (other than swing line loans) bear interest, at the Company’s option, at either an Alternate Base Rate or an Adjusted Term SOFR Rate (both as defined in the Credit Agreement) plus an applicable margin, which will vary from 0.000% to 0.250% in the case of loans bearing interest at the Alternate Base Rate and 0.680% to 1.250% in the case of loans bearing interest at the Adjusted Term SOFR Rate, in each case based upon the better of the ratings assigned to our debt by Moody’s Investor Service, Inc. and Standard & Poor’s Rating Services, subject to limited exceptions. Swing line loans made under the Revolving Credit Facility bear interest at an Alternate Base Rate plus the applicable margin for Alternate Base Rate loans. In addition, the Company pays a facility fee on the aggregate amount of the commitments under the Credit Agreement in an amount equal to a percentage of such commitments, varying from 0.070% to 0.250% per annum. The interest rate margins and facility fee are based upon the better of the ratings assigned to the Company’s debt by Moody’s Investor Service, Inc. and Standard & Poor’s Ratings Services, subject to limited exceptions. As of December 31, 2023, based upon the Company’s current credit ratings, its margin for Alternate Base Rate loans was 0.000%, its margin for Term Benchmark Revolving Loans was 0.900% and its facility fee was 0.100%. ​ The Credit Agreement contains certain covenants, including limitations on subsidiary indebtedness, a minimum consolidated fixed charge coverage ratio of 2.50:1.00 and a maximum consolidated leverage ratio of 3.50:1.00. The consolidated fixed charge coverage ratio includes a calculation of earnings before interest, taxes, depreciation, amortization, rent, and non-cash share-based compensation expense to fixed charges. Fixed charges include interest expense, capitalized interest, and rent expense. The consolidated leverage ratio includes a calculation of adjusted debt to earnings before interest, taxes, depreciation, amortization, rent, and non-cash share-based compensation expense. Adjusted debt includes outstanding debt, outstanding stand-by letters of credit, and similar instruments, and five-times rent expense and excludes any premium or discount recorded in conjunction with the issuance of long-term debt. In the event that the Company should default on any covenant (subject to customary grace periods, cure rights, and materiality thresholds) contained in the Credit Agreement, certain actions may be taken, including, but not limited to, possible termination of commitments, immediate payment of outstanding principal amounts plus accrued interest and other amounts payable under the Credit Agreement, and litigation from lenders. As of December 31, 2023, the Company remained in compliance with all covenants under the Credit Agreement. ​ In addition to the letters of credit issued under the Credit Agreement described above, as of December 31, 2023 and 2022, the Company had other outstanding letters of credit, primarily to support obligations under workers’ compensation, general liability, and other insurance policies, in the amount of $106.8 million and $96.6 million, respectively. Substantially all of these letters of credit have a one-year term from the date of issuance and were not issued under the Company’s Credit Agreement or another committed facility. ​ Commercial paper program: On August 9, 2023, the Company established a commercial paper program (the “Program”) pursuant to which it may issue short-term, unsecured commercial paper notes (the “Notes”) under the exemption from registration contained in Section 4(a)(2) of the Securities Act of 1933, as amended. Amounts available under the Program may be borrowed, repaid, and re-borrowed from time to time, with the aggregate face or principal amount of the Notes outstanding under the Program at any time not to exceed $1.8 billion. The Notes will have maturities of up to 397 days from the date of issue. The Notes rank at least pari passu with all of the Company’s other unsecured and unsubordinated indebtedness. The Company plans to use its Revolving Credit Facility as a liquidity backstop for the repayment of Notes outstanding under the Program. The Notes issued under the Program were included in “Long-term debt” on the accompanying Consolidated Balance Sheet as of December 31, 2023, as the Company has the ability and intent to refinance these Notes on a long-term basis. ​ Senior notes: On June 15, 2023, the Company’s $300 million aggregate principal amount of unsecured 3.850% Senior Notes due 2023 matured, and the Company repaid these notes using borrowings under its Revolving Credit Facility. ​ On November 20, 2023, the Company issued $750 million aggregate principal amount of unsecured 5.750% Senior Notes due 2026 (“5.750% Senior Notes due 2026”) at a price to the public of 99.954% of their face value with U.S. Bank Trust Company, National Association (“U.S. Bank”) as trustee. Interest on the 5.750% Senior Notes due 2026 is payable on May 20 and November 20 of each year, beginning on May 20, 2024, and is computed on the basis of a 360-day year. ​ As of December 31, 2023, the Company has issued and outstanding a cumulative $4.9 billion aggregate principal amount of unsecured senior notes, which are due between 2026 and 2032, with UMB Bank, N.A. and U.S. Bank Trust Company as trustees. Interest on the senior notes, ranging from 1.750% to 5.750%, is payable semi-annually and is computed on the basis of a 360-day year. None of the Company’s subsidiaries is a guarantor under the senior notes. Each of the senior notes is subject to certain customary covenants, with which the Company complied as of December 31, 2023.
