Accounting pronouncements [Abstract]
Description of New Accounting Pronouncements Not Yet Adopted and Recently Adopted	Accounting pronouncements Recently adopted accounting pronouncements ASU No. 2010-16, Entertainment-Casinos (Topic 924): Accruals for Casino Jackpot Liabilities The Financial Accounting Standards Board (the “FASB”) issued ASU No. 2010-16, Entertainment-Casinos (Topic 924): Accruals for Casino Jackpot Liabilities. The guidance clarifies that an entity should not accrue jackpot liabilities (or portions thereof) before a jackpot is won if the entity can avoid paying that jackpot since the machine can legally be removed from the gaming floor without payment of the base amount. Jackpots should be accrued and charged to revenue when an entity has the obligation to pay the jackpot. This guidance applies to both base jackpots and the incremental portion of progressive jackpots. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2010. This guidance should be applied by recording a cumulative-effect adjustment to opening retained earnings in the period of adoption. Under the gaming regulations in the various jurisdictions in which the Company operates, the removal of base jackpots is not prohibited and upon adoption, the Company reduced its recorded accrual by $5.6 million ($3.4 million net of tax) with a corresponding cumulative-effect increase to retained earnings. Recently issued accounting pronouncements ASU No. 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS The FASB issued ASU No. 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS (“International Financial Reporting Standards”). The guidance amends and converges U.S. GAAP and IFRS requirements for measuring amounts at fair value as well as disclosures regarding these measurements. The update is effective in the fourth quarter of 2011. The Company does not expect the adoption of this Topic to have a material impact on its consolidated financial statements. ASU No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income The FASB issued ASU No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income in June 2011. This update changes the requirements for the presentation of other comprehensive income, eliminating the option to present components of other comprehensive income as part of the statement of stockholders’ equity, among other items. The guidance requires that all non-owner changes in stockholders’ equity be presented in either a single continuous statement of comprehensive income or in two separate but consecutive statements. The FASB has proposed to defer the requirement for companies to present reclassification adjustments for each component of other comprehensive income on the face of the financial statements; however, the presentation requirement under this update will still be effective for fiscal years and interim periods beginning after December 15, 2011. Since the update only requires a change in presentation, the Company does not expect the adoption of this Topic to have a material impact on its consolidated financial statements. ASU No. 2011-08, Intangibles - Goodwill and Other (Topic 350): Testing Goodwill for Impairment The FASB issued ASU No. 2011-08, Intangibles - Goodwill and Other (Topic 350): Testing Goodwill for Impairment in September 2011. This update simplifies how entities test goodwill for impairment. Under the amendments in this update, an entity is not required to calculate the fair value of a reporting unit unless the entity determines that it is more likely than not that its fair value is less than its carrying amount by assessing qualitative factors. The amendments are effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Since the update does not amend the performance of the two-step goodwill impairment test, the Company does not expect the adoption of this Topic to have a material impact on its consolidated financial statements.
