Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The consolidated interim financial statements included herein are unaudited and have been prepared by the Company pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been omitted pursuant to such rules and regulations; however, the Company believes that the disclosures are adequate to make the information presented not misleading. The consolidated interim financial statements include the accounts of the Company and all of its wholly-owned and majority-owned subsidiaries. Investments in which the Company does not have a controlling interest or is not the primary beneficiary, but has the ability to exert significant influence, are accounted for under the equity method of accounting. All inter-company accounts and transactions have been eliminated in consolidation. For the three and six months ended June 30, 2015, the noncontrolling interest in our former South Korean subsidiary is recorded net of tax as Net income attributable to noncontrolling interest. In October 2015, the Company sold its remaining ownership position in its South Korean subsidiary. See Note 7 - Discontinued Operations. These statements reflect all normal recurring adjustments that, in the opinion of management, are necessary for fair presentation of the information contained herein. These consolidated interim financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. The Company adheres to the same accounting policies in preparing interim financial statements. As permitted under U.S. GAAP, interim accounting for certain expenses, including income taxes, are based on full year assumptions. Such amounts are expensed in full in the year incurred. For interim financial reporting purposes, income taxes are recorded based upon estimated annual income tax rates. We have reclassified certain amounts previously reported in our financial statements to conform to the current presentation, including amounts related to discontinued operations. Unless noted otherwise, discussions in these notes pertain to our continuing operations.
Recently issued accounting pronouncements, policy	RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, which supersedes the revenue recognition guidance in Accounting Standard Codification (“ASC”) 605, Revenue Recognition. The new guidance clarifies the principles for recognizing revenue and develops a common revenue standard for U.S. GAAP and International Financial Reporting Standards. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes the most current revenue recognition guidance. In July 2015, the FASB approved a one-year deferral of the effective date of this ASU. With this deferral, the amended guidance is effective retrospectively for reporting periods (interim and annual) beginning after December 15, 2017. We are currently assessing the potential impact of this ASU on our consolidated financial position and results of operations. In January 2016, the FASB issued ASU No. 2016-01, which revises the guidance in ASC 825-10, Recognition and Measurement of Financial Assets and Financial Liabilities, and provides guidance for the recognition, measurement, presentation, and disclosure of financial assets and liabilities. The guidance is effective for reporting periods (interim and annual) beginning after December 15, 2017, for public companies. We are currently assessing the potential impact of this ASU on our consolidated financial position and results of operations. In February 2016, the FASB issued ASU No. 2016-02, which supersedes the lease accounting guidance in ASC 840, Leases. The new guidance which requires lessees to recognize a right-of-use asset and a lease liability on the balance sheet for all leases with the exception of short-term leases. For lessees, leases will continue to be classified as either operating or finance leases in the income statement. Lessor accounting is similar to the current model but updated to align with certain changes to the lessee model. The guidance is effective for reporting periods (interim and annual) beginning after December 15, 2018, for public companies, with early adoption permitted. The new guidance must be adopted using a modified retrospective approach. We are currently assessing the potential impact of this ASU on our consolidated financial position and results of operations. In March 2016, the FASB issued ASU No. 2016-09, which revises the guidance in ASC 718, Compensation - Stock Compensation, and will change how companies account for certain aspects of share-based payments to employees, including the income tax impact, classification on the statement of cash flows and forfeitures. The guidance is effective for reporting periods (interim and annual) beginning after December 15, 2017, for public companies. Early adoption is permitted. We are currently assessing the potential impact of this ASU on our consolidated financial position and results of operations. Recently Adopted Accounting Pronouncements Effective January 1, 2016, the Company retrospectively adopted ASU No. 2015-03 and No. 2015-15 related to simplifying the presentation of debt issuance costs. The adoption of this new guidance resulted in a change to the presentation of deferred financing costs related to our credit facilities and 3.50% convertible senior notes due 2019 from an asset to a direct deduction from the corresponding debt liability, consistent with the presentation of debt discounts and premiums. Adoption did not impact the Company’s results of operations or cash flows for any period presented. See Note 15 - Long-Term Debt. Effective January 1, 2016, the Company adopted ASU 2015-05 which clarified how a customer in a cloud computing arrangement should determine whether the arrangement includes a software license. Under this new guidance, if a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The ASU did not change the customer's accounting treatment of service contracts. Previously, the Company was required to analogize to lease accounting guidance when determining the asset acquired in a software licensing arrangement. As permitted under the guidance, the Company adopted the new guidance prospectively to all new or materially modified arrangements entered into on or after the effective date. The adoption of this guidance did not impact the Company’s results of operations, financial position, or cash flows.
Stock-based compensation, policy	STOCK-BASED COMPENSATION The Company awards non-vested stock to employees, directors and executive officers in the form of Restricted Stock Awards (“RSAs”) and Restricted Stock Units (“RSUs”), market-based RSAs and RSUs, performance-based RSAs and RSUs and stock options. The Compensation Committee of the Company’s Board of Directors approves stock-based compensation awards for all employees and executive officers of the Company. The Corporate Governance and Nominating Committee of the Company’s Board of Directors approves stock-based compensation awards for all non-employee directors of the Company. The Company uses the fair-market value of the Company’s common stock on the date the award is approved to measure fair value for service-based and performance-based awards, a Monte Carlo simulation model to determine both the fair value and requisite service period of market-based awards and the Black-Scholes option-pricing model to determine the fair value of stock option awards. The Company presents as a financing activity in the consolidated statement of cash flows the benefits of tax deductions in excess of the tax-effected compensation of the related stock-based awards for the options exercised and vested RSAs and RSUs. Compensation expense for stock option awards and service-based awards is recognized ratably over the requisite service period. For market-based awards, compensation expense is recognized over the requisite service period as derived using a Monte Carlo simulation model. If an award includes both a market and performance or service condition, the requisite service period is adjusted in the event the market condition is satisfied prior to the end of the derived service period. For performance-based awards, compensation expense is recognized based on the probability of achieving the performance conditions associated with the respective shares, as determined by management.
