Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Principles of Consolidation	— Basis of Presentation and Principles of Consolidation Basis of Presentation and Use of Estimates Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“GAAP”), which require the use of estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities. Actual amounts could differ from those estimates. Certain immaterial prior year amounts have been reclassified to conform to the current year’s presentation. Consolidation of Subsidiaries and Variable Interest Entities Our consolidated financial statements include the accounts of Caesars Entertainment and its subsidiaries after elimination of all intercompany accounts and transactions. We consolidate all subsidiaries in which we have a controlling financial interest and variable interest entities (“VIEs”) for which we or one of our consolidated subsidiaries is the primary beneficiary. Control generally equates to ownership percentage, whereby (1) affiliates that are more than 50% owned are consolidated; (2) investments in affiliates of 50% or less but greater than 20% are generally accounted for using the equity method where we have determined that we have significant influence over the entities; and (3) investments in affiliates of 20% or less are generally accounted for using the cost method. We consolidate a VIE when we have both the power to direct the activities that most significantly impact the results of the VIE and the right to receive benefits or the obligation to absorb losses of the entity that could be potentially significant to the VIE. For VIEs that are under common control with affiliates, in lieu of an assessment of the power to direct the activities that most significantly impact the results of the VIE, we may be required to assess a number of other factors to determine the consolidating entity, including the following: (i) the closeness of the association that the VIE has with the businesses of the affiliated entities, (ii) the entity from which the VIE obtained its assets; (iii) the nature of ongoing management and other agreements; and (iv) the obligation to absorb losses and the right to receive residual returns that could potentially be significant to the VIE. Along with the VIEs that are consolidated in accordance with the above guidelines, we also hold variable interests in other VIEs that are not consolidated because we are not the primary beneficiary. We continually monitor both consolidated and unconsolidated VIEs to determine if any events have occurred that could cause the primary beneficiary to change. A change in determination could have a material impact on our financial statements. Despite a majority financial interest, we may only possess non-substantive voting rights that do not confer upon us the ability to control key activities of the entity, such as determining operating budgets, payment of obligations, management of assets, and/or other activities necessary for the ordinary course of business. We continually monitor both consolidated and unconsolidated VIEs to determine if any events have occurred that could cause the primary beneficiary to change. Consolidation of Caesars Growth Partners Because the equity holders in CGP receive returns disproportionate to their voting interests and substantially all the activities of CGP are related to Caesars, CGP has been determined to be a VIE. CAC is the sole voting member of CGP. Common control exists between CAC and Caesars through the majority beneficial ownership of both by Hamlet Holdings (as defined in Note 19). The assets held by CGP originally came from Caesars and continue to be intrinsically closely associated with Caesars through the nature of the business, as well as ongoing service and management agreements. Additionally, Caesars is expected to receive the majority of the benefits or absorb the majority of the losses from its higher economic participation in CGP. We have determined that Caesars is the primary beneficiary of CGP as a result of the close association with Caesars and other factors such as the fact that all of the assets and businesses owned by CGP were acquired from Caesars, and therefore, we are required to consolidate them. Neither CAC nor CGP guarantees any of CEC’s debt, and the creditors or beneficial holders of CGP have no recourse to the general credit of CEC. We account for the noncontrolling interest in CGP using the hypothetical liquidation at book value (“HLBV”) method to attribute the earnings and losses of CGP between the controlling and noncontrolling interest. Under this method, the noncontrolling interest in the CGP entity is based upon the noncontrolling interest holders’ contractual claims on CGP’s accounting balance sheet pursuant to the mandatory liquidation provisions of the operating agreement, adjusted for certain common control tax distributions and the Notes Distribution described in Note 13. Caesars’ resulting net income from the controlling interest is the residual net income from the consolidation of the VIE less the HLBV calculated net income attributable to the noncontrolling interest holder. Due to certain mandatory liquidation provisions of the operating agreement, this could result in a net loss to Caesars consolidated results in periods in which CGP reports net income. Subject to the terms and conditions described in the certificate of incorporation of CAC and the operating agreement of CGP, after October 21, 2016, Caesars Entertainment will have the right to acquire all or a portion of the voting units of CGP (or, at the election of CAC, shares of CAC’s Class A common stock) not otherwise owned by Caesars Entertainment at such time. The purchase consideration may be, at Caesars Entertainment’s option, cash or shares of Caesars Entertainment’s common stock valued at market value, net of customary market discount and expenses, provided that the cash portion will not exceed 50% of the total consideration in any exercise of the call right. The purchase price will be the greater of (i) the fair market value of the voting units of CGP (or shares of CAC’s Class A common stock) at such time based on an independent appraisal or (ii) the initial capital contribution in respect of such units plus a 10.5% per annum return on such capital contribution, subject to a maximum return on such capital contribution of 25% per annum, taking into account prior distributions with respect to such units. CGP generated net revenues of $2.3 billion and $1.6 billion for the years ended December 31, 2015 and 2014, respectively. Net loss attributable to Caesars related to CGP was $18 million and $405 million for the years ended December 31, 2015 and 2014, respectively. The noncontrolling interest balance attributable to CGP as of December 31, 2015 was $1.2 billion. CGP is obligated to issue non-voting membership units (the “units”) to CEC in 2016 to the extent that the earnings from CIE’s social and mobile games business exceeds a specified threshold amount in 2015. The number of units to be received by CEC is capped at a value of $225 million divided by the value of the units as of the date of CGP’s formation in 2013. CGP recognized a liability representing the estimated fair value of the units they expected issue to CEC, which was $347 million as of December 31, 2014. As of December 31, 2015, CIE’s earnings had exceeded the threshold and the number of units is no longer variable. As a result, CGP reclassified the fair value of the units to additional paid in capital, which was $228 million as of December 31, 2015. The value of the units is eliminated in our consolidation of CGP. CGP consolidates into its financial statements the accounts of any variable interest entity for which it is determined to be the primary beneficiary. Caesars Baltimore Investment Company, LLC (“CBIC”), a wholly-owned subsidiary of CGP, indirectly holds interests in the owner of the Horseshoe Baltimore Casino (“Horseshoe Baltimore”) in Maryland. CBIC has an ownership interest in CR Baltimore Holdings (“CRBH”), a variable interest entity. CBIC has been determined to be the primary beneficiary of CRBH, and therefore, consolidates CRBH into its financial statements. As CBIC is wholly-owned by CGP, CGP therefore also consolidates CRBH. In addition to CGP, we also hold immaterial variable interests in other VIEs that are not consolidated because we are not the primary beneficiary. We continually monitor both consolidated and non-consolidated VIEs to determine if any events have occurred that could cause the primary beneficiary to change. Consolidation of Caesars Enterprise Services A steering committee acts in the role of a board of managers for CES with each Member entitled to appoint one representative to the steering committee. Each Member, through its representative, is entitled to a single vote on the steering committee, accordingly, the voting power of the Members does not equate to their ownership percentages. We have determined that because Caesars consolidates two of the Members (CERP and CGPH), Caesars is deemed to have a controlling financial interest in CES through our ownership of that interest. As described in Note 3, effective January 15, 2015, CEOC is no longer a consolidated subsidiary. Therefore, CEOC’s ownership interest in CES, totaling $23 million, is accounted for as noncontrolling interest. Consolidation Considerations for Caesars Entertainment Operating Company As described in Note 3, CEOC’s filing for reorganization was a reconsideration event for Caesars Entertainment to reevaluate whether consolidation of CEOC continued to be appropriate. We have concluded that CEOC is a VIE and that we are not the primary beneficiary of CEOC.

— Basis of Presentation and Principles of Consolidation

Basis of Presentation and Use of Estimates

Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“GAAP”), which require the use of estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities. Actual amounts could differ from those estimates.

Certain immaterial prior year amounts have been reclassified to conform to the current year’s presentation.

Consolidation of Subsidiaries and Variable Interest Entities

Our consolidated financial statements include the accounts of Caesars Entertainment and its subsidiaries after elimination of all intercompany accounts and transactions.

We consolidate all subsidiaries in which we have a controlling financial interest and variable interest entities (“VIEs”) for which we or one of our consolidated subsidiaries is the primary beneficiary. Control generally equates to ownership percentage, whereby (1) affiliates that are more than 50% owned are consolidated; (2) investments in affiliates of 50% or less but greater than 20% are generally accounted for using the equity method where we have determined that we have significant influence over the entities; and (3) investments in affiliates of 20% or less are generally accounted for using the cost method.

We consolidate a VIE when we have both the power to direct the activities that most significantly impact the results of the VIE and the right to receive benefits or the obligation to absorb losses of the entity that could be potentially significant to the VIE.

CGP consolidates into its financial statements the accounts of any variable interest entity for which it is determined to be the primary beneficiary.

CBIC has an ownership interest in CR Baltimore Holdings (“CRBH”), a variable interest entity. CBIC has been determined to be the primary beneficiary of CRBH, and therefore, consolidates CRBH into its financial statements. As CBIC is wholly-owned by CGP, CGP therefore also consolidates CRBH.

In addition to CGP, we also hold immaterial variable interests in other VIEs that are not consolidated because we are not the primary beneficiary. We continually monitor both consolidated and non-consolidated VIEs to determine if any events have occurred that could cause the primary beneficiary to change.

Consolidation of Caesars Enterprise Services

A steering committee acts in the role of a board of managers for CES with each Member entitled to appoint one representative to the steering committee. Each Member, through its representative, is entitled to a single vote on the steering committee, accordingly, the voting power of the Members does not equate to their ownership percentages. We have determined that because Caesars consolidates two of the Members (CERP and CGPH), Caesars is deemed to have a controlling financial interest in CES through our ownership of that interest.

As described in Note 3, effective January 15, 2015, CEOC is no longer a consolidated subsidiary. Therefore, CEOC’s ownership interest in CES, totaling $23 million, is accounted for as noncontrolling interest.

Consolidation Considerations for Caesars Entertainment Operating Company

As described in Note 3, CEOC’s filing for reorganization was a reconsideration event for Caesars Entertainment to reevaluate whether consolidation of CEOC continued to be appropriate. We have concluded that CEOC is a VIE and that we are not the primary beneficiary of CEOC.
