Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We recorded income tax expense of $0.2 million and $0.5 million for the three and nine months ended September 30, 2015, which was primarily comprised of state and foreign taxes. We recorded income tax expense of $0.2 million and $0.7 million for the three and nine months ended September 30, 2014, which was primarily comprised of state and foreign taxes. Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the carrying amounts of existing assets and liabilities in the financial statements and their respective tax bases using tax rates expected to be in effect during the years in which the basis differences reverse. We believe it is more likely than not that our federal and state net deferred tax assets will not be fully realized. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of a deferred tax asset will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. A valuation allowance is recorded for loss carryforwards and other deferred tax assets where it is more likely than not that such deferred tax assets will not be realized. Accordingly, we continue to maintain a valuation allowance against all of our net deferred tax assets as of September 30, 2015. Due to past losses in the U.S., we have a full valuation allowance on the U.S. federal and state deferred tax assets. We will continue to maintain a full valuation allowance against our net federal, state and certain foreign deferred tax assets until there is sufficient evidence to support recoverability of our deferred tax assets. We had $2.4 million and $2.2 million of unrecognized tax benefits as of September 30, 2015 and December 31, 2014. We do not anticipate a material change to our unrecognized tax benefits over the next twelve months. Unrecognized tax benefits may change during the next twelve months for items that arise in the ordinary course of business.
