Subsequent Events [Abstract]
Subsequent Events	Subsequent EventsOn April 8, 2021, we entered into the Fifth Amended and Restated Credit Agreement (our "new credit agreement") to replace our Fourth Amended and Restated Credit Agreement. Our new credit agreement provides for a $950 million senior secured credit facility, comprising a term loan facility of $300 million and a revolving loan facility of $650 million, with the ability to increase the aggregate size of the revolving loan facility by an additional $200 million subject to lender consent and certain other customary conditions. The new credit agreement matures on March 15, 2024, subject to extension at our request for one additional year on up to two occasions and subject to certain conditions. On April 22, 2021 we completed our offering of an additional $250 million in aggregate principal amount of our 2027 Notes. The additional notes constitute an additional issuance of our existing 2027 Notes that we issued on December 17, 2020 in an aggregate principal amount of $750 million. The additional $250 million of notes have identical terms as (other than with respect to the issue price) and constitute part of the same series of the 2027 Notes we issued on December 17, 2020. The $250 million of the 2027 Notes were issued at a premium of 103.75%, plus accrued interest from December 17, 2020. We intend to use the net proceeds from the offering for general partnership purposes, including repaying a portion of the revolving borrowings outstanding under our new revolving loan facility.
