We manage our operations through five operating segments:

•	TwinSpires, which includes TwinSpires.com, Fair Grounds Account Wagering, Velocity, BetAmerica and Bloodstock Research Information Services;


•	Casino, which includes Oxford Casino ("Oxford"), Riverwalk Casino ("Riverwalk"), Harlow's Casino ("Harlow’s"), Calder Casino, Fair Grounds Slots, Video Services, LLC ("VSI"), 50% equity investment in MVG, 50% equity investment in Ocean Downs and 25% equity investment in SCH, which includes investments in Saratoga Casino Hotel, Saratoga Casino Black Hawk and Ocean Downs;

•	Corporate, which includes miscellaneous and other revenue, compensation expense, professional fees and other general and administrative expense not allocated to our other operating segments.

Big Fish Games is a global producer and distributor of social casino, casual and mid-core free-to-play, and premium paid games for PC, Mac and mobile devices. On January 9, 2018, we closed the Big Fish Transaction, at which time Big Fish Games ceased to be an operating segment. Due to the Big Fish Transaction, the Company has presented Big Fish Games as held for sale and discontinued operations in the accompanying condensed consolidated financial statements and these notes. The Company has not allocated corporate and other certain expenses to Big Fish Games consistent with the discontinued operations presentation in the accompanying condensed consolidated statements of comprehensive income. Accordingly, the prior year amounts were reclassified to conform to this presentation.

Eliminations include the elimination of intersegment transactions. We utilize non-GAAP measures, including EBITDA (earnings before interest, taxes, depreciation and amortization) and adjusted EBITDA. Our chief operating decision maker utilizes adjusted EBITDA to evaluate segment performance, develop strategy and allocate resources. Adjusted EBITDA includes the following adjustments:

Adjusted EBITDA includes our portion of the EBITDA from our equity investments.

Adjusted EBITDA excludes:


•	Transaction expense, net which includes:


•	Acquisition and disposition related charges, including fair value adjustments related to earnouts and deferred payments; and


•	Other transaction expense, including legal, accounting, and other deal-related expense;


•	Stock-based compensation expense;


•	Asset impairments;


•	Gain on Calder land sale;


•	Calder exit costs;


•	Loss on extinguishment of debt;


•	Pre-opening expense; and


•	Other charges, recoveries and expenses

We utilize the adjusted EBITDA metric because we believe the inclusion or exclusion of certain non-recurring items is necessary to provide a more accurate measure of our core operating results and enables management and investors to evaluate and compare from period to period our operating performance in a meaningful and consistent manner. Adjusted EBITDA should not be considered as an alternative to operating income as an indicator of performance, as an alternative to cash flows from operating activities as a measure of liquidity, or as an alternative to any other measure provided in accordance with GAAP. Our calculation of adjusted EBITDA may be different from the calculation used by other companies and, therefore, comparability may be limited. For segment reporting, adjusted EBITDA includes intercompany revenue and expense totals that are eliminated in the accompanying condensed consolidated statements of comprehensive income.

The tables below present net revenue from external customers and intercompany revenue from each of our operating segments, adjusted EBITDA by segment and reconciles comprehensive income to adjusted EBITDA:
