Going Concern Note	CEOC has sufficient liquidity at present, including CEOC’s ability to borrow under any of its credit arrangements as described in Note 9, "Debt." However, CEOC estimates that, absent a refinancing, amendment, private restructuring, or a reorganization under Chapter 11 of the Bankruptcy Code, based on its current operating forecasts and the underlying assumptions, that it would require additional sources of liquidity to fund its operations and obligations beginning during the fourth quarter of 2015. These factors raise substantial doubt as to CEOC's ability to continue as a going concern beyond the fourth quarter of 2015. These financial statements do not include any adjustments that might result from the outcome of this uncertainty.
