Loss Contingency, Allegations				On March 21, 2014, CEC, CEOC, CERP, Caesars Acquisition Company ("CAC"), and CGP LLC received a letter (the “March 21 Letter”) from a law firm acting on behalf of unnamed clients who claim to hold Second-Priority Secured Notes of CEOC, alleging, among other things, that CEOC is insolvent and that CEOC’s owners improperly transferred or seek to transfer valuable assets of CEOC to affiliated entities in connection with: (a) the transaction agreement dated October 21, 2013 by and among CEC, certain subsidiaries of CEC and CEOC, CAC and CGP LLC, which, among other things, provides for the asset transfers from subsidiaries of CEOC to CGP LLC of Planet Hollywood Las Vegas and interests in Horseshoe Baltimore that was consummated in 2013; (b) the transfer by CEOC to CERP of Octavius Tower and Linq that was consummated in 2013; and (c) the contemplated transfers by CEOC to CGP LLC of the Properties. The March 21 Letter does not identify the holders or specify the amount of Second-Priority Secured Notes of CEOC or other securities that they may hold. The March 21 Letter includes allegations that these transactions constitute or will constitute voidable fraudulent transfers and represent breaches of alleged fiduciary duties owed to CEOC creditors and that certain disclosures concerning the transactions were inadequate. The March 21 Letter demands, among other things, that the transactions be rescinded or terminated, as would be applicable. CEC strongly believes there is no merit to the March 21 Letter’s allegations and will defend itself vigorously and seek appropriate relief should any action be brought.	On April 3, 2014, a letter was sent to CEC, the Board of Directors of CEC (the “CEC Board”) and the Board of Directors of CEOC (the “CEOC Board” and, together with the CEC Board, the “Boards”) (the “April 3 Letter”) by a law firm claiming to act on behalf of unnamed parties who assert that they are lenders under CEOC’s credit agreement and/or holders of CEOC’s first priority senior secured notes (collectively, the “First Lien Group”), alleging, among other things, that CEC and CEOC improperly transferred or seek to transfer assets of CEC and CEOC to affiliated entities in connection with: (a) the transaction agreement dated October 21, 2013 by and among CEC, certain subsidiaries of CEC and CEOC, CAC and CGP LLC, which, among other things, provides for the contributions by CEC and its subsidiaries to CGP LLC of CIE and $1.1 billion face amount of CEOC’s unsecured notes in exchange for non-voting interests of CGP LLC, and the asset transfers from subsidiaries of CEOC to CGP LLC of the Planet Hollywood casino and interests in Horseshoe Baltimore that was consummated in 2013; (b) the transfer by CEOC to CERP of Octavius Tower and Linq that was consummated in 2013 ((a) and (b) collectively, the “2013 Transactions”); and (c) the contemplated transfers by CEOC to CGP LLC of the Properties and formation of a new services joint venture between CEOC, CERP and CGP LLC to provide certain centralized services, including but not limited to common management of enterprise-wide intellectual property (the “Contemplated Transaction”). The April 3 Letter asserts that the consideration provided by CGP LLC and CERP in connection with the 2013 Transactions and the Contemplated Transaction is inadequate and that CEC and CEOC were insolvent at the time the transactions were approved. The April 3 Letter claims that the First Lien Group consists of institutions that collectively hold in excess of $1.85 billion of CEOC’s first lien debt and that holders of an additional $880 million of CEOC’s first lien debt endorse and support the April 3 Letter. The April 3 Letter alleges, among other things, that these transactions represent breaches of alleged fiduciary duties owed to CEOC creditors and that certain disclosures concerning the transactions were inadequate. The April 3 Letter demands, among other things, that the transactions be rescinded or terminated, as would be applicable, and requests a meeting with representatives of CEC and other parties to discuss these matters. CEC strongly believes there is no merit to the April 3 Letter’s allegations and will defend itself vigorously and seek appropriate relief should any action be brought.
