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 affected. 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.

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 requires additional qualitative and quantitative disclosures to assess the amount, timing, and uncertainty of cash flows arising from leases. 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. Leases embedded in other arrangements will be accounted for separately by allocating payments between lease and nonlease components. As a practical expedient, lessees are permitted to make an accounting policy election by class of underlying asset to account for each lease and nonlease component as a single lease component. The amended guidance will not require us to re-evaluate land easements that exist or expired before adoption that were not previously accounted for as a lease under Topic 840. 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. We plan to adopt the new standard on its effective date of January 1, 2019. We are currently assessing our processes and system capabilities. The qualitative and quantitative effects of adoption are still being analyzed as we are in the process of cataloging our existing lease contracts and identifying arrangements containing embedded leases.

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 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.
