Our effective tax rate increased from a benefit of 17.3% for the three months ended June 30, 2019 to an expense of 68.5% for the three months ended June 30, 2020 and decreased from a benefit of 6.2% for the six months ended June 30, 2019 to a benefit of 22.9% for the six months ended June 30, 2020. The change in the effective tax rate for the three months ended June 30, 2020 was impacted by tax expense in our international operations and additional changes in the valuation allowance related to our domestic operations. The change in the effective tax rate for the three and six months ended June 30, 2019 was primarily driven by the shift to profitability for the three and six months ended June 30, 2019, with tax expense being offset by a 29.1% rate reduction related to a transfer pricing study completed during the second quarter of 2019 that resulted in the assignment of operating expenditures to specific Company locations, and the effective income tax rates among the respective jurisdictions. The decrease in the effective tax rate for the six months ended June 30, 2020 was primarily driven by a tax benefit of $7.4 million recognized during the six months ended June 30, 2020 as a result of the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) signed into law on March 27, 2020, which allowed for the carryback of federal net operating losses, partially offset with tax expense in our international operations and changes in our valuation allowance related to our domestic operations. An increase in the valuation allowance against our domestic deferred tax assets was recorded in the amount of $3.6 million during the three and six months ended June 30, 2020.

The Company continually reviews the adequacy of its valuation allowance and recognizes the benefits of deferred tax assets only as the reassessment indicates that it is more likely than not that the deferred tax assets will be recognized in accordance with ASC 740, Income Taxes. As of June 30, 2020, the Company had deferred tax assets totaling $59.8 million, and a valuation allowance totaling $52.2 million had been established against those deferred tax assets. The remaining $7.6 million in deferred tax assets not offset by a valuation allowance is located in various foreign jurisdictions where the Company believes that it is more likely than not that we will realize these deferred tax assets. Our assessment of the realizability of our deferred tax assets includes the evaluation of evidence, some of which requires significant judgement, including historical operating results, the evaluation of our three-year cumulative income position, future taxable income projections and tax planning strategies. Should management’s conclusion change in the future and additional valuation allowance or a partial or full release of the valuation allowance is necessary, it could have a material effect on our consolidated financial statements.
