Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On April 6, 2017, certain subsidiaries of the Partnership (collectively, the “Sellers”) entered into an Asset Purchase Agreement (the “Purchase Agreement”) with 7-Eleven, Inc., a Texas corporation (“7-Eleven”) and SEI Fuel Services, Inc., a Texas corporation and wholly-owned subsidiary of 7-Eleven (“SEI Fuel,” and, together with 7-Eleven, referred to herein collectively as “Buyers”). Pursuant to the Purchase Agreement, Sellers have agreed to sell a portfolio of approximately 1,100 company-operated retail fuel outlets in 19 geographic regions, together with ancillary businesses and related assets, including the Laredo Taco Company (the “Business”), for an aggregate purchase price of $3.3 billion, payable in cash, plus the value of inventory at the closing of the transactions contemplated by the Purchase Agreement (the “Closing”) and the assumption of certain liabilities related to the Business by Buyers. The purchase price is subject to certain adjustments, including (i) those relating to specified items that arise during post-signing due diligence and inspections and (ii) individual properties not ultimately being acquired by Buyers due to the failure to obtain necessary third party consents or waivers or because either Buyers or Sellers exercise their respective rights, under certain circumstances, to cause a specific property to be excluded from the transaction. In addition, each of the Partnership and Sunoco LLC have guaranteed Sellers’ obligations under the Purchase Agreement and related ancillary agreements pursuant to a guarantee agreement (the “Guarantee Agreement”) entered into in connection with the Purchase Agreement. In connection with the Closing, Sellers and Buyers and their respective affiliates will enter into a number of ancillary agreements, including a 15-year “take-or-pay” fuel supply agreement between Sunoco LLC and SEI Fuel. The Closing is expected to occur in the fourth quarter of 2017, and is subject to the satisfaction or waiver of customary closing conditions for a transaction of this type, including the receipt of any approvals required under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. With the assistance of a third-party brokerage firm, we have begun marketing efforts with respect to approximately 208 Stripes sites located in certain West Texas, Oklahoma and New Mexico markets in which 7-Eleven is prohibited from operating convenience stores. Our broker is also assisting us in marketing approximately 42 convenience stores in Tennessee and Georgia. These properties will be sold by market in an “all or nothing” format, with bids expected to be due by late May 2017. If the 42 sites in Tennessee and Georgia are not sold in connection with this process, per the Asset Purchase Agreement with 7-Eleven they will be included in the transaction and sold to 7-Eleven.
