9. Income Taxes

The effective income tax rate for the three months ended June 30, 2019 and 2018 was 0.2% and 6.3%, respectively, resulting in a $2,000, and $123,000 income tax benefit, respectively. The effective income tax rate for the six months ended June 30, 2019 and 2018 was 3.4% and 9.2%, respectively, resulting in a $67,000 and $372,000 income tax benefit, respectively. The difference in the effective income tax rate for the three and six months ended June 30, 2019, compared to the three and six months ended June 30, 2018, is mainly attributable to the decrease in tax rates pursuant to the U.S. Tax Cuts and Jobs Act, and a change in the valuation allowance. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred income tax assets will not be realized. The ultimate realization of deferred income tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred income tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Based on the consideration of these items, management has determined that enough uncertainty exists relative to the realization of the deferred income tax asset balances to warrant the application of a full valuation allowance as of June 30, 2019 and December 31, 2018.

The U.S. Tax Cuts and Jobs Act subjects a U.S. parent shareholder to current tax on its “global intangible low-taxed income” (GILTI). We are allowed under ASC 740 to elect an accounting policy choice of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current period expense when incurred or (2) factoring such amounts into the Company’s measurement of its deferred taxes. The Company has elected to account for GILTI as a current period expense when incurred.
