Segment And Geographic Information [Abstract]
Segment And Geographic Information	15.  SEGMENT AND GEOGRAPHIC INFORMATION The Company reports its financial performance in three reportable segments based on the geographical locations in which its casinos operate: the United States, Canada and Poland. The Company views each market in which it operates as a separate operating segment and each casino or other operation within those markets as a reporting unit. Operating segments are aggregated within reportable segments based on their similar economic characteristics, types of customers, types of services and products provided, the regulatory environments in which they operate, and their management and reporting structure. The Company’s operations related to Century Casino Bath, which the Company deconsolidated in May 2020, its concession, management and consulting agreements and certain other corporate and management operations have not been identified as separate reportable segments; therefore, these operations are included in Corporate and Other in the following segment disclosures to reconcile to consolidated results. All intercompany transactions are eliminated in consolidation. The table below provides information about the aggregation of the Company’s reporting units and operating segments into reportable segments as of December 31, 2021: Reportable SegmentOperating SegmentReporting UnitUnited StatesColoradoCentury Casino & Hotel - Central City Century Casino & Hotel - Cripple Creek West VirginiaMountaineer Casino, Racetrack & Resort MissouriCentury Casino Cape Girardeau Century Casino CaruthersvilleCanadaEdmontonCentury Casino & Hotel - Edmonton Century Casino St. Albert Century Mile Racetrack and Casino CalgaryCentury Downs Racetrack and Casino Century SportsPolandPolandCasinos PolandCorporate and OtherCorporate and OtherCruise Ships & Other Corporate Other The Company’s chief operating decision maker is a management function comprised of two individuals. These two individuals are the Company’s Co-Chief Executive Officers. The Company’s chief operating decision makers and management utilize Adjusted EBITDA as a primary profit measure for its reportable segments. Adjusted EBITDA is a non-US GAAP measure defined as net earnings (loss) attributable to Century Casinos, Inc. shareholders before interest expense (income), net, income taxes (benefit), depreciation, amortization, non-controlling interest (earnings) losses and transactions, pre-opening expenses, acquisition costs, non-cash stock-based compensation charges, asset impairment costs, (gain) loss on disposition of fixed assets, discontinued operations, (gain) loss on foreign currency transactions, cost recovery income and other, gain on business combination and certain other one-time transactions. Expense related to the Master Lease is included in the interest expense (income), net line item. Intercompany transactions consisting primarily of management and royalty fees and interest, along with their related tax effects, are excluded from the presentation of net earnings (loss) and Adjusted EBITDA reported for each segment. Non-cash stock-based compensation expense is presented under Corporate and Other in the tables below as the expense is not allocated to reportable segments when reviewed by the Company’s chief operating decision makers. ‎ The following tables provide summary information regarding the Company’s reportable segments: For the year ended December 31, 2021Amounts in thousands United States Canada Poland Corporate and Other TotalNet operating revenue (1) $283,285 $46,428 $58,226 $567 $388,506 Earnings (loss) before income taxes $49,628 $3,312 $921 $(25,712) $28,149 Net earnings (loss) attributable to Century Casinos, Inc. shareholders $49,628 $1,124 $440 $(30,570) $20,622Interest expense (income), net (2) 28,229 1,796 (477) 13,110 42,658Income taxes — 1,256 257 4,858 6,371Depreciation and amortization 18,398 4,904 3,028 432 26,762Net earnings attributable to non-controlling interests — 932 224 — 1,156Non-cash stock-based compensation — — — 2,652 2,652Gain on foreign currency transactions, cost recovery income and other (3) (836) (545) (887) (418) (2,686)Loss (gain) on disposition of fixed assets 341 43 44 (37) 391Adjusted EBITDA $95,760 $9,510 $2,629 $(9,973) $97,926 Long-lived assets (4) $376,210 $152,278 $29,865 $3,412 $561,765 Total assets $422,409 $179,297 $44,204 $57,448 $703,358 Capital expenditures $8,672 $646 $163 $531 $10,012 (1)Net operating revenue for the Corporate and Other segment primarily relates to the Company’s cruise ship operations.(2)Expense of $28.2 million related to the Master Lease is included in interest expense (income), net in the United States segment.
