New Accounting Pronouncement or Change in Accounting Principle, Description	Amended guidance addresses intra-entity transfers of assets other than inventory, which requires the recognition of any related income tax consequences when such transfers occur. The amendments should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. Amendments are effective for fiscal years beginning after December 15, 2017, and interim reporting periods within those years. Early adoption is permitted. We are currently assessing the effect the adoption of this standard will have on our financial statements.

New Accounting Pronouncements or Change in Accounting Principle [Line Items]
New Accounting Pronouncement or Change in Accounting Principle, Description	Created a new Topic 606, Revenue from Contracts with Customers. The new guidance is intended to clarify the principles for recognizing revenue and to develop a common revenue standard for GAAP applicable to revenue transactions. Existing industry guidance will be eliminated, including revenue recognition guidance specific to the gaming industry. The FASB has recently issued several amendments to the standard, including clarification on accounting for and identifying performance obligations. This guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those reporting periods. The guidance should be applied using the full retrospective method or retrospectively with the cumulative effect initially applying the guidance recognized at the date of initial application. We are currently in the process of our analysis and anticipate this standard will have a material effect on our consolidated financial statements. As described below, we expect the most significant effect will be related to the accounting for the Total Rewards customer loyalty program and casino promotional allowances. However, due to the complexity and nature of the gaming industry, the quantitative effects of these changes have not yet been determined and are still being analyzed. The Total Rewards customer loyalty program affects revenue from our four core businesses: casino entertainment, food and beverage, rooms and hotel, and entertainment and other business operations. Currently, CEC estimates the cost of fulfilling the redemption of Reward Credits, after consideration of estimated forfeitures (referred to as “breakage”), based upon the cost of historical redemptions. Upon adoption of the new guidance, Reward Credits will no longer be recorded at cost, and a deferred revenue model will be used to account for the classification and timing of revenue recognized as well as the classification of related expenses when Reward Credits are redeemed. This will result in a portion of casino revenues being recorded as deferred revenue and being recognized as revenue in a future period when the Reward Credits are redeemed, and the revenue will be classified according to the good or service for which the Reward Credits were redeemed (e.g., a hotel room). We also expect to see a significant decrease in casino revenues. The presentation of goods and services provided to customers without charge in gross revenue with a corresponding reduction in promotional allowances will no longer be reported. Revenue will be recognized based on relative standalone selling prices for transactions with more than one performance obligation. For example, when a casino customer is given a complimentary room, we will be required to allocate a portion of the casino revenues earned from the customer to rooms revenues based on the standalone selling price of the room. We will continue to monitor and assess the impact of any changes to the standard and interpretations as they become available.
New Accounting Pronouncement or Change in Accounting Principle, Description of Transition Method	We plan to adopt this standard effective January 1, 2018, on a full retrospective basis.

New Accounting Pronouncements or Change in Accounting Principle [Line Items]
New Accounting Pronouncement or Change in Accounting Principle, Description	Amended certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Among other things, they require equity investments (except those accounted for under the equity method of accounting or those that result in consolidation) to be measured at fair value with any changes in fair value recognized in net income and simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Early adoption is permitted on certain provisions. We are currently assessing the effect the adoption of this standard will have on our financial statements, but do not expect the effect to be material.
Accounting Standards Update 2016-02 [Member]
New Accounting Pronouncements or Change in Accounting Principle [Line Items]
New Accounting Pronouncement or Change in Accounting Principle, Description	The amended guidance requires most lease obligations to be recognized as a right-of-use (“ROU”) asset with a corresponding liability on the balance sheet. The guidance also requires additional qualitative and quantitative disclosures to assess the amount, timing, and uncertainty of cash flows arising from leases. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The guidance should be implemented for the earliest period presented using a modified retrospective approach, which includes optional practical expedients primarily focused on leases that commenced before the effective date, including continuing to account for leases that commenced before the effective date in accordance with previous guidance, unless the lease is modified. Currently, all of our capital leases are set to expire before the initial effective date and will not require any accounting adjustments. Accounting for our operating leases where we are the lessor, including leases for the Octavius Tower at Caesars Palace Las Vegas and gaming space at The LINQ promenade, will remain unchanged. However, after the Debtors consummated their reorganization pursuant to the Plan, New CEOC will be a wholly owned subsidiary of CEC, and this lease transaction would be eliminated upon consolidation. Operating leases, including agreements relating to slot machines, will be recorded on the balance sheet as an ROU asset with a corresponding lease liability, which will be amortized using the effective interest rate method as payments are made. The ROU asset will be depreciated on a straight-line basis and recognized as lease expense. The qualitative and quantitative effects of adoption are still being analyzed. We are in the process of evaluating the full effect the new guidance will have on our financial statements.
