New Accounting Pronouncements or Change in Accounting Principle [Line Items]
New Accounting Pronouncement or Change in Accounting Principle, Description	Amended guidance provides miscellaneous changes to clarify, correct errors in, or make minor improvements to the ASC. These amendments make the ASC easier to understand and easier to apply by eliminating inconsistencies and providing clarifications. Many of the amendments in this update do not have transition guidance and were effective upon issuance of the update. We assessed these updates and noted no applicability to Caesars. However, several amendments in this update do have transition guidance with effective dates for annual periods beginning after December 15, 2018 for public business entities. We are currently assessing the effect the adoption of the remaining amendments in this standard will have on our financial statements.

The amendments in this update are effective for public entities for fiscal years ending after December?15,?2020. Early adoption is permitted.

New Accounting Pronouncement or Change in Accounting Principle, Description	Amended guidance expands the scope of employee share-based payments to include share-based payment transactions for acquiring goods and services from nonemployees. Equity-classified share-based payment awards issued to nonemployees will be measured on the grant date, instead of the previous requirement to remeasure the awards through the performance completion date. This amended guidance also clarifies that any share-based payment awards issued to customers should be evaluated under ASC 606, Revenue from Contracts with Customers.

ASU 2018-02 Income Statement—Reporting Comprehensive Income (Topic 220)
New Accounting Pronouncements or Change in Accounting Principle [Line Items]
New Accounting Pronouncement or Change in Accounting Principle, Description	Amendments in this update allow a reclassification from accumulated other comprehensive income to retained earnings effectively eliminating the stranded tax effects resulting from the Tax Cuts and Jobs Act (the U.S. federal government enacted a tax bill, H.R.1, An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018) (the ?Tax Act?). Because the amendments only relate to the reclassification of the income tax effects of the Tax Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not impacted. The amendments in this update are effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. Amendments in this update should be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Act is recognized. We are currently assessing the effect the adoption of this standard will have on our financial statements.
ASU 2016-02 Leases (Topic 842)
New Accounting Pronouncements or Change in Accounting Principle [Line Items]
New Accounting Pronouncement or Change in Accounting Principle, Description	The amended guidance is intended to increase transparency and comparability among organizations by requiring additional disclosures to reflect the significance of an entity?s leasing arrangements and by recognizing right-of-use (?ROU?) assets and lease liabilities on the balance sheet. Many long-term operating leases, including agreements relating to real estate, may 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. Certain leases embedded in other arrangements, such as service and supplier contracts, may be accounted for separately by allocating payments between lease and non-lease components. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. We will adopt the new standard on January 1, 2019, and we have elected to apply the guidance as of the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings. Under this method, comparative periods will continue to be reported under legacy lease accounting guidance consistent with previously issued financial statements. We are currently assessing the effects the guidance will have on our financial statements and related disclosures.
ASU 2016-13 Financial Instruments—Credit Losses (Topic 326)
New Accounting Pronouncements or Change in Accounting Principle [Line Items]
New Accounting Pronouncement or Change in Accounting Principle, Description	Amended guidance replaces the incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. Amendments affect entities holding financial assets and net investments in leases that are not accounted for at fair value through net income. The amendments affect loans, debt securities, trade receivables, net investments in leases, off-balance-sheet credit exposures, reinsurance receivables and any other financial assets not excluded from the scope that have the contractual right to receive cash. Amendments are effective for fiscal years beginning after December?15,?2019, including interim periods within those fiscal years. Early adoption is permitted. We are currently assessing the effect the adoption of this standard will have on our financial statements.
