Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES We apply an estimated annual effective tax rate (“ETR”) approach for calculating a tax provision for interim periods, as required under GAAP. We recorded a provision for income taxes of $0.1 million and a benefit for income taxes of $1.2 million for the six months ended June 30, 2015 and 2014, respectively. Our ETR differs from the U.S. federal statutory tax rate of 35% primarily as a result of nondeductible expenses, state income taxes, foreign income taxes, and the impact of a valuation allowance on our deferred tax assets. Our provision for income taxes is computed using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for the expected future tax benefit to be derived from tax loss and credit carryforwards. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. A valuation allowance is established when it is more likely than not the future realization of all or some of the deferred tax assets will not be achieved. The evaluation of the need for a valuation allowance is performed on a jurisdiction by jurisdiction basis, and includes a review of all available positive and negative evidence. We recognize excess tax benefits associated with share-based compensation to stockholders’ equity only when realized. When assessing whether excess tax benefits relating to share-based compensation have been realized, we follow the with-and-without approach, excluding any indirect effects of the excess tax deductions. Under this approach, excess tax benefits related to share-based compensation are not deemed to be realized until after the utilization of all other tax benefits available to us. We recognize the impact of a tax position in our financial statements only if that position is more likely than not of being sustained upon examination by taxing authorities, based on the technical merits of the position. Any interest and penalties related to uncertain tax positions will be reflected in income tax expense.

INCOME TAXES

We apply an estimated annual effective tax rate (“ETR”) approach for calculating a tax provision for interim periods, as required under GAAP.
