Income Taxes	8. INCOME TAXES The Company is subject to income tax in the U.S. as well as other tax jurisdictions in which it conducts business.

The Company recorded an income tax expense of $0.1 million and $0.1 million for the three months ended March 31, 2018 and 2017, respectively, related to foreign income taxes and state minimum taxes. Based on the available objective evidence during the three months ended March 31, 2018, the Company believes it is more likely than not that the tax benefits 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 local statutory tax rate relates to the valuation allowance on the Company’s U.S. losses. Effective January 1, 2018, the Company adopted the new revenue standard which results in a change to deferred revenues. The change in deferred revenues impacts the deferred tax asset arising out of deferring revenues for GAAP compared to for tax.

The Tax Cuts and Job Act (TCJA) of 2017, enacted on December 22, 2017, contains significant changes to U.S. tax law, including lowering the U.S. corporate income tax rate to 21% and implementing a territorial tax system. TCJA creates a new requirement that global intangible low-taxed income (GILTI) earned by controlled foreign corporations (CFCs) must be included currently in the gross income of the CFCs’ U.S. shareholder. Under U.S. GAAP, the Company is allowed to make an accounting policy choice of either (i) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the “period cost method”) or (ii) factoring such amounts into a company’s measurement of its deferred taxes (the “deferred method”). The Company’s selection of an accounting policy with respect to the new GILTI tax rules will depend, in part, on analyzing the global income to determine whether the Company expects to have future U.S. inclusions in taxable income related to GILTI and, if so, what the impact is expected to be. The Company has included GILTI in the annual effective tax rate calculation, however, it has not made a policy decision regarding whether to record deferred taxes on GILTI.
