12.	Income Taxes

We calculate our provision for federal, state and international income taxes based on current tax law. The Tax Act, which was enacted on December 22, 2017, included several key provisions impacting accounting for and reporting of income taxes. The most significant provisions, effective for periods beginning after December 31, 2017, are the global intangible low-taxed income (“GILTI”) provision and the reduction of the U.S. corporate statutory tax rate from 35% to 21%.

We file income tax returns in various federal, state and local jurisdictions. Tax years from 2014 forward remain open for examination by Federal authorities. Tax years from 2012 forward remain open for all significant state and foreign authorities.

We account for uncertain tax positions pursuant to ASC Topic 740, “Income Taxes.” As of September 30, 2018 and December 31, 2017, the liability for uncertain tax positions totaled approximately $0.9 million, which is included in Other liabilities on our Condensed Consolidated Balance Sheets. We recognize accrued interest related to uncertain tax positions and penalties, if any, in income tax expense within the Condensed Consolidated Statements of Operations.

Certain of the Company’s undistributed earnings of our foreign subsidiaries are not permanently reinvested. Our cash needs for operating, investing and financing activities have increased in the U.S. Since foreign earnings have already been subject to U.S. income tax in 2017 as a result of the Tax Act, we intend to repatriate foreign-held cash as needed. As of September 30, 2018, and December 31, 2017 we have recorded deferred income taxes of approximately $0.5 million and zero, respectively, on the undistributed earnings of our foreign subsidiaries. This amount is attributable primarily to the foreign withholding taxes that would become payable should we decide to repatriate cash held in our foreign operations.

We recognized the provisional tax impacts related to the deemed repatriation of foreign earnings and the benefit for the revaluation of deferred tax assets and liabilities during the year ended December 31, 2017. ASU 2018-05 allows a company to record a provisional amount when it does not have the necessary information available, prepared, or analyzed in reasonable detail to complete its accounting for the change in the tax law. We adjusted our provisional accounting for the impacts of the Tax Act as they relate to the repatriation of foreign cash. No other adjustments were made to these provisional amounts for the three-month and nine-month periods ended September 30, 2018. We continue to review and evaluate the provisions of the Tax Act. This review could result in changes to the amounts we have provisionally recorded. We will complete our accounting for the tax effects of the Tax Act before the end of the one-year measurement period allowed by ASU 2018-05, which will be in the fourth quarter of 2018. The amounts recorded in 2018 to account for the impact of the Tax Act for periods beginning after December 31, 2017 are the Company’s best estimates based on the current data and guidance available. We have not yet determined our accounting policy election with respect to recording deferred taxes for basis differences related to the GILTI provisions or to continue to record as a period cost.
