Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The (benefit from) provision for income taxes consists of provisions for federal, state, and foreign income taxes. The Company operates globally with operations in various tax jurisdictions outside of the United States. Accordingly, the effective income tax rate is a composite rate reflecting the geographic mix of earnings in various tax jurisdictions and the applicable rates. Our interim provision for income taxes is measured using an estimated annual effective tax rate, adjusted for discrete items that occur within the periods presented. The tax effect of discrete items is recorded in the quarter in which they occur. Our future effective tax rates could be adversely affected by earnings being lower than anticipated in countries with lower statutory rates, greater losses than anticipated in countries with lower statutory tax rates, increases in recorded valuation allowances of tax assets, or changes in tax laws or interpretations thereof. Our effective tax rate differs from the Federal United States statutory tax rate of 35% due to accrual of state taxes, non-deductible expenses, foreign earnings and losses taxed at different rates, accrual of interest on tax liabilities, and the effect of valuation allowances on deferred tax assets. We record valuation allowances primarily on tax benefits of losses arising in certain unprofitable countries in international markets and certain U.S. Foreign Tax credits. The tax provision during the six months ended June 30, 2016 was increased by approximately $1,964 of discrete items, consisting primarily of tax valuation allowances recorded on tax benefits of current year operating losses in certain foreign tax jurisdictions, deficiencies in tax benefits on stock based compensation, and accrued interest on unrecognized tax positions. In addition, during the three months ended June 30, 2016, the Company recorded a pre-tax charge for estimated impairment of goodwill in the amount of $142,002. The Company recorded a deferred tax benefit of $27,137 with respect to the portion of impaired goodwill which is deductible for tax purposes (see Note 13 - Goodwill and Intangible Assets for additional details). The tax provision during the six months ended June 30, 2015 reflects a provision of $7,735 attributable to discrete items, consisting primarily of a tax provision of $4,896 due to a gain related to the partial sale of our equity interest in a company located in Australia (see Note 10 - Investments), and increases to tax valuation allowances of $1,915 on tax benefits of current year losses incurred in certain foreign tax jurisdictions. In addition, as a result of settlement of a tax examination during the first quarter of 2015, the Company recorded a tax benefit due to recognition of previously unrecognized tax positions of $10,424 which, net of deferred tax benefits and valuation allowances, impacted the effective rate by $6,776. The Company also reversed accrued interest and penalties on unrecognized tax positions of $12,607 which, on a net of tax basis, impacted the effective tax rate by $8,977. The total benefit reflected in the tax provision in the six months ended June 30, 2015 relating to recognition of previously unrecognized tax positions, and reversals of accrued interest and penalties thereon, was $15,753. The tax matters relate primarily to allocation of income among tax jurisdictions. The Company is currently under examination by several domestic and international tax authorities, including the United States Internal Revenue Service. Presently, no material adjustments have been proposed. Significant judgment is required in evaluating our uncertain tax positions and determining our provision for income taxes. The gross recorded liability for uncertain tax positions (inclusive of estimated interest and penalties thereon) as of June 30, 2016 and December 31, 2015 is recorded on the Company’s consolidated balance sheets as long-term income taxes payable of $36,507 and $36,348, respectively. Interest and penalties related to underpayment of income taxes are classified as a component of income tax expense in the consolidated statements of operations and comprehensive income (loss). The Company estimates that it is reasonably possible that unrecorded tax benefits may be reduced by an amount ranging from $0 to $4,000 in the next twelve months due to expirations of statutes of limitations or settlement of tax examinations. The tax matters concerned relate to the allocation of income among jurisdictions and the amount of prior year tax loss carryovers.
