Subsequent Event [Member] | National Retirement Fund Lawsuit [Member]
Subsequent Event [Line Items]
Subsequent Event, Description		In January 2015, the National Retirement Fund (“NRF”), a multi-employer defined benefit pension plan, voted to expel Caesars Entertainment and its participating subsidiaries (“CEC Group”) from the plan. NRF claims that CEOC’s bankruptcy presents an “actuarial risk” to the plan because, depending on the outcome of the bankruptcy proceeding, Caesars Entertainment might no longer be liable to the plan for any partial or complete withdrawal liability. NRF has advised the CEC Group that its expulsion has triggered withdrawal liability with a present value of approximately $360 million, payable in 80 quarterly payments of about $6 million. Caesars Entertainment vigorously disputes NRF’s legal and contractual authority to take such action and has challenged NRF’s actions in the appropriate legal forums.
