⁽¹⁾ On December 22, 2017, the United States enacted tax reform legislation commonly known as the Tax Cuts and Jobs Act (the “Tax Act”), resulting in significant modifications to existing law. As a result of the changes under the Tax Act, the Company recorded incremental income tax expense of $5,323 during the year ended December 31, 2017, which consisted primarily of the remeasurement of deferred tax assets and liabilities at the new federal statutory rate of 21%. Prior to the enactment of the Tax Act, deferred tax assets and liabilities were measured at the previous federal statutory rate of 35%.
