Income Taxes The Company’s effective tax rate for the three- and nine-month periods ended September 30, 2016 was 47.8% and 34.3%, respectively, compared to 31.0% and 25.8%, respectively, for the corresponding periods in the prior year. For the current three- and nine-month periods, the effective tax rate was higher than the U.S. statutory tax rate of 34% primarily due to unbenefited domestic losses, partially offset by lower statutory tax rates in foreign jurisdictions. For the three- and nine-month periods ended September 30, 2015, the effective tax rate differed from the U.S. statutory rate of 34% primarily due to the lower statutory tax rate in Sweden, partially offset by unbenefited domestic losses. As of December 31, 2015, the Company had U.S. net operating loss carryforwards of approximately $46,984,000 and U.S. business tax credit carryforwards of approximately $1,920,000 available to reduce future federal income taxes, if any. The net operating loss and business tax credits carryforwards will continue to expire at various dates through December 2035. Net operating loss carryforwards and available tax credits are subject to review and possible adjustment by the Internal Revenue Service and may be limited in the event of certain changes in the ownership interest of significant stockholders. As of December 31, 2015, the Company concluded that realization of deferred tax assets in the United States beyond December 31, 2015 is not more likely than not, and as such, the Company maintained a valuation allowance against the majority of its remaining deferred tax assets. As of September 30, 2016, the Company concluded that realization of deferred tax assets beyond September 30, 2016 is not more likely than not, and as such, the Company maintained a valuation allowance against the majority of its remaining U.S. deferred tax assets. As a result of the Company’s acquisition of Atoll on April 1, 2016, the Company acquired intangible assets of approximately $7,561,000. Because the amortization of these intangible assets is not deductible under German tax law, the Company recorded deferred tax liabilities of approximately $2,202,000 as part of the Atoll Acquisition. Additionally, the Company was able to retain net operating losses of approximately $3,039,000. Accordingly, the Company recorded deferred tax assets of approximately $885,000 as part of the Atoll Acquisition. The fiscal years ended December 31, 2012, 2013, 2014 and 2015 are subject to examination by U.S. federal, state, Germany and Sweden taxing authorities.
