Income Taxes	11. INCOME TAXES Income tax benefit for the three months ended March 31, 2019, was $0.14 million, compared to an expense of $0.13 million, for the three months ended March 31, 2018. The income tax benefit for the three months ended March 31, 2019, was primarily attributable to non-U.S. tax benefit associated with the Company's non-U.S. operation. The income tax expense for the three months ended March 31, 2018, related to foreign income taxes and state minimum taxes. Based on the available objective evidence during the three months ended March 31, 2019, the Company believes it is more likely than not that the tax benefit of the U.S. losses incurred may not be realized. Accordingly, the Company recorded a full valuation allowance against the tax benefits of the U.S. losses incurred. The primary difference between the effective tax rate and the statutory tax rate relates to the valuation allowance on the Company’s U.S. losses. A valuation allowance is provided when it is more likely than not that some portion of the deferred tax assets will not be realized through future operations. As a result of the Company’s analysis of all available objective evidence, both positive and negative, as of March 31, 2019, management believes it is more likely than not that the deferred tax assets will not be fully realizable. Accordingly, the Company has provided a full valuation allowance against its deferred tax assets with the exception of deferred tax assets related to foreign entities in the U.K., China, and Denmark.
