Revenue Recognition, Policy [Policy Text Block] | Seasonality Racing Due to the seasonal nature of our live racing business, revenue and operating results for any interim quarter are generally not indicative of the revenues and operating results for the year and may not be comparable with results for the corresponding period of the previous year. Historically, we have had fewer live racing days during the first quarter of each year, and the majority of our live racing revenue occurs during the second quarter, with the running of the Kentucky Derby and the Kentucky Oaks. We conducted 60 live thoroughbred racing days during the third quarters of 2016 and 2015. For the nine months ended September 30, 2016, we conducted 175 live thoroughbred racing days, which compares to 183 live racing days during the nine months ended September 30, 2015. Casinos Casino revenue and earnings have historically been higher during the first quarter due to seasonal revenue from our predominately southern casino properties. TwinSpires Due to the seasonal nature of the racing business, revenue and operating results for any interim quarter are generally not indicative of the revenues and operating results for the year and may not be comparable with results for the corresponding period of the previous year. Historically, our revenue is higher in the second quarter with the running of the Kentucky Derby and the Kentucky Oaks. Big Fish Games Revenue from our Big Fish Games, Inc. ("Big Fish Games") segment also have a seasonal component and are typically lower during the summer months.

- Definition Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction. + References Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 235 -SubTopic 10 -Section 50 -Paragraph 4 -URI http://asc.fasb.org/extlink&oid=68058157&loc=d3e18823-107790 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 605 -SubTopic 10 -Section S99 -Paragraph 1 -Subparagraph (SAB Topic 13.B.Q1) -URI http://asc.fasb.org/extlink&oid=65893310&loc=d3e214044-122780 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 235 -SubTopic 10 -Section 50 -Paragraph 3 -URI http://asc.fasb.org/extlink&oid=68058157&loc=d3e18780-107790 Reference 4: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 235 -SubTopic 10 -Section 50 -Paragraph 1 -URI http://asc.fasb.org/extlink&oid=68058157&loc=d3e18726-107790 + Details
