| Asset Impairment                                         | ASSET IMPAIRMENTDuring the quarter ended March 31, 2020, the Company evaluated whether events or circumstances changed that would indicate it is more likely than not that any of its intangible assets, goodwill, or property and equipment, were impaired ("Trigger Event"), or if there were any other than temporary impairments of our equity investments.  Factors considered in this evaluation included, among other things, the amount of the fair value over carrying value from the annual impairment testing performed as of April 1, 2019, changes in carrying values, changes in discount rates, and the impact of temporary property closures due to the COVID-19 pandemic on cash flows.  Based on the Company's evaluation, the Company concluded that a Trigger Event occurred related to the Presque Isle gaming rights, trademark, and the reporting unit's goodwill due to the impact and uncertainty of the COVID-19 pandemic and the recent closing of the Presque Isle Transaction in 2019. The initial fair value of Presque Isle gaming rights in the first quarter of 2019 was determined using the Greenfield Method, which is an income approach methodology that calculates the present value based on a projected cash flow stream.  This method assumes that the Presque Isle gaming rights provide the opportunity to develop a casino and online wagering platform in a specified region, and that the present value of the projected cash flows are a result of the realization of advantages contained in these rights.  Under this methodology, the acquirer is expected to absorb all start-up costs, as well as incur all expenses pertaining to the acquisition and/or the creation of all tangible and intangible assets.  The estimated future revenue, operating expenses, start-up costs, and discount rate were the primary inputs in the valuation.  Based on the Trigger Event, the Company updated the discount rate to reflect the increased uncertainty of the cash flows and updated the projected cash flow stream.  As a result, the Company recognized an impairment of $15.0 million in first quarter of 2020 for its Presque Isle gaming rights ($12.5 million related to the Gaming segment and $2.5 million related to the Online Wagering segment).The Presque Isle trademark was initially valued in first quarter of 2019 using the relief-from-royalty method of the income approach, which estimates the fair value of the intangible asset by discounting the fair value of the hypothetical royalty payments a market participant would be willing to pay to enjoy the benefits of the asset.  The estimated future revenue, royalty rate, and discount rate were the primary inputs in the valuation of the trademark. Based on the Trigger Event, the Company updated the discount rate to reflect the increased uncertainty of the cash flows and updated projected cash flow stream.  As a result, the Company recognized an impairment of $2.5 million in first quarter of 2020 for its Presque Isle trademark.The fair value of the Presque Isle reporting unit's goodwill was determined under the market and income valuation approaches using inputs primarily related to discounted projected cash flows and price multiples of publicly traded comparable companies.  In accordance with Accounting Standards Codification 350, Intangibles - Goodwill and Other, the Company performed its impairment testing of the Presque Isle gaming rights and trademark prior to testing Presque Isle goodwill.  Based on the Trigger Event, the Company updated the discount rate to reflect the increased uncertainty of the cash flows and updated project cash flow stream.  As a result, the Company did not recognize an impairment for Presque Isle goodwill in first quarter of 2020 because the fair value exceeded the carrying value. |
