Subsequent Events [Abstract]
Subsequent Events	20. Subsequent Events: On February 11, 2022, we issued $400 million of 5.375% unsecured senior notes due 2030 (the “2030 Notes”). We used the net proceeds from the issuance of the 2030 Notes, together with $100 million drawn under our Revolving Credit Line (as defined below), $250 million of Term A Loan (as defined below) and approximately $308 million of cash on hand, to redeem (the “Redemption”) our 6.25% senior unsecured notes due 2027 (the “2027 Notes”), which had an outstanding principal balance of $1.0 billion, and to pay costs, fees and expenses associated with the Redemption and the Credit Agreement Amendment (as defined below). Interest on the 2030 Notes accrues at the rate of 5.375% per annum, or annual interest expense of $21.5 million. Interest under the 2030 Notes is payable semi-annually in arrears on February 15 and August 15, beginning on August 15, 2022. Our obligations under the 2030 Notes are guaranteed on an unsecured senior basis by the same subsidiaries and affiliated professional contractors that guarantee the Amended Credit Agreement. The indenture under which the 2030 Notes are issued, among other things, limits our ability to (1) incur liens and (2) enter into sale and lease-back transactions, and also limits our ability to merge or dispose of all or substantially all of our assets, in all cases, subject to a number of customary exceptions. Although we are not required to make mandatory redemption or sinking fund payments with respect to the 2030 Notes, upon the occurrence of a change in control, we may be required to repurchase the 2030 Notes at a purchase price equal to 101% of the aggregate principal amount of the 2030 Notes repurchased plus accrued and unpaid interest. Also in connection with the Redemption, we amended and restated the Credit Agreement (the “Credit Agreement Amendment”) concurrently with the issuance of the 2030 Notes. The Credit Agreement, as amended by the Credit Agreement Amendment (the “Amended Credit Agreement”), among other things, (i) refinanced the prior unsecured revolving credit facility with a $450 million unsecured revolving credit facility, including a $37.5 million sub-facility for the issuance of letters of credit (the “Revolving Credit Line”), and a new $250 million term A loan facility (“Term A Loan”) and (ii) removed JPMorgan Chase Bank, N.A., as the administrative agent under the Credit Agreement and appointed Bank of America, N.A. as the administrative agent for the lenders under the Amended Credit Agreement. The Amended Credit Agreement matures on February 11, 2027 and is guaranteed on an unsecured basis by substantially all of our subsidiaries and affiliated professional contractors. At our option, borrowings under the Amended Credit Agreement bear interest at (i) the Alternate Base Rate (defined as the highest of (a) the prime rate as announced by Bank of America, N.A., (b) the Federal Funds Rate plus 0.50% and (c) Term SOFR for an interest period of one month plus 1.00% with a 1.00% floor) plus an applicable margin rate of 0.50% for the first two fiscal quarters after the date of the Credit Agreement Amendment, and thereafter at an applicable margin rate ranging from 0.125% to 0.750% based on our consolidated net leverage ratio or (ii) Term SOFR rate (calculated as the Secured Overnight Financing Rate published on the applicable Reuters screen page plus a spread adjustment of 0.10%, 0.15% or 0.25% depending on if we select a one-month, three-month or six-month interest period, respectively, for the applicable loan with a 0% floor), plus an applicable margin rate of 1.50% for the first two full fiscal quarters after the date of the Credit Agreement Amendment, and thereafter at an applicable margin rate ranging from 1.125% to 1.750% based on our consolidated net leverage ratio. The Amended Credit Agreement also provides for other customary fees and charges, including an unused commitment fee with respect to the Revolving Credit Line ranging from 0.150% to 0.200% of the unused lending commitments under the Revolving Credit Line, based on our consolidated net leverage ratio. The Amended Credit Agreement contains customary covenants and restrictions, including covenants that require us to maintain a minimum interest coverage ratio, a maximum consolidated total consolidated net leverage ratio and to comply with laws, and restrictions on the ability to pay dividends, incur indebtedness or liens and make certain other distributions subject to baskets and exceptions, in each case, as specified therein. Failure to comply with these covenants would constitute an event of default under the Amended Credit Agreement, notwithstanding the ability of the company to meet its debt service obligations. The Credit Agreement includes various customary remedies for the lenders following an event of default, including the acceleration of repayment of outstanding amounts under the Credit Agreement. In addition, we may increase the principal amount of the Revolving Credit Line or incur additional term loans under the Amended Credit Agreement in an aggregate principal amount such that on a pro forma basis after giving effect to such increase or additional term loans, we are in compliance with the financial covenants, subject to the satisfaction of specified conditions and additional caps in the event that the Credit Agreement is secured.
