Investment, Restructuring and Acquisitions [Abstract]
Investment, Restructuring and Acquisition Activities	Investment, Restructuring and Acquisition Activities Merger Agreement with GLPI: On April 28, 2016, we completed the transactions contemplated under the terms of the Merger Agreement, dated as of July 20, 2015. The Merger Agreement effectuated the Spin-Off of Former Pinnacle’s operations (and Belterra Park property and excess land at certain locations) into OpCo, an independent publicly traded company, after which Former Pinnacle merged with and into Gold Merger Sub, with Gold Merger Sub surviving the Merger as a wholly-owned subsidiary of GLPI. Following the Merger, OpCo was renamed Pinnacle Entertainment, Inc., and is now the operator of the gaming facilities acquired by GLPI under the Master Lease. The Master Lease has an initial term of 10 years with five subsequent, five-year renewal periods at our option. The Company will pay initial annual rent of $377 million to GLPI. In completing the Merger, each share of common stock, par value $0.10 per share, of Former Pinnacle (the “Former Pinnacle Common Stock”) issued and outstanding immediately prior to the effective time (other than shares of Former Pinnacle Common Stock (i) owned or held in treasury by Former Pinnacle or (ii) owned by GLPI, its subsidiaries or Merger Sub) were canceled and converted into the right to receive 0.85 shares of common stock, par value $0.01 per share, of GLPI. As further described in Note 2, “Long-Term Debt,” in connection with the Spin-Off and Merger, the Company made a dividend to Former Pinnacle of $808.4 million, which was equal to the amount of debt outstanding at the time of the closing of the Merger, less $2.7 billion that GLPI assumed pursuant to the Merger Agreement. Following the consummation of the Spin-Off and Merger, the Company had no outstanding obligations under Former Pinnacle’s Credit Facility, the 6.375% Notes, the 7.50% Notes, the 7.75% Notes and the 8.75% Notes. Acquisition of the Meadows Business: On March 29, 2016, we entered into a purchase agreement (the “Purchase Agreement”) with GLP Capital, L.P. (“GLPC”), a subsidiary of GLPI, pursuant to which we will acquire the Meadows located in Washington County, Pennsylvania for total consideration of approximately $138 million. Following the close of the transaction, we will own and operate the Meadows’ gaming entertainment and harness racing business subject to a triple-net lease of its underlying real property with GLPI (the “Meadows Lease”). The Meadows Lease will provide for a 10-year initial term, including renewal terms at our option, up to a total of 29 years. The initial annual rent will be $25.5 million, comprised of a base rent of $14.0 million, which is subject to annual escalation in the future, and an initial percentage rent of $11.5 million, which will adjust every two years. The completion of the transaction is subject to various closing conditions, including obtaining the approval of the Pennsylvania Gaming Control Board and the Pennsylvania Harness Racing Commission. The Company anticipates funding the acquisition with its Revolving Credit Facility. Subject to the satisfaction or waiver of conditions in the Purchase Agreement, we expect the transaction to close by the end of the third quarter of 2016. Equity Method Investment: We have invested in a land re-vitalization project in downtown St. Louis, which is accounted for under the equity method and included in “Other assets, net” in our unaudited Condensed Consolidated Balance Sheets. As of both March 31, 2016, and December 31, 2015, the carrying amount of this investment was $1.7 million. Retama Park Racetrack: We hold 75.5% of the equity of Pinnacle Retama Partners, LLC (“PRP”) and consolidate the accounts of PRP in our unaudited Condensed Consolidated Financial Statements. As of March 31, 2016, PRP held $14.9 million in promissory notes issued by Retama Development Corporation (“RDC”), a local government corporation of the City of Selma, Texas, and $11.3 million in local government corporation bonds issued by RDC, at amortized cost. The promissory notes and local government corporation bonds, which are included in “Other assets, net” in our unaudited Condensed Consolidated Balance Sheets, have long-term contractual maturities and are collateralized by the assets of the Retama Park Racetrack. The contractual terms of the promissory notes include interest payments due at maturity; however, we have not recorded accrued interest because uncertainty exists as to RDC’s ability to make the interest payments. We have the positive intent and ability to hold the local government corporation bonds to maturity and until the amortized cost basis is recovered.
