Income Taxes	13. Income Taxes The Company’s effective tax rate for the three and six months ended June 30, 2016 was 27.9% and 30.5%, respectively, compared to 17.0% and 23.5%, respectively, for the corresponding periods in the prior year. For the current three and six month periods, the effective tax rate was lower than the U.S. statutory tax rate of 34% primarily due to increased foreign profits at lower tax rates, offset by unbenefited domestic losses. For the three and six months ended June 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 and a reserve reversal attributable to a correction of an income tax audit accrual. As of December 31, 2015, the Company has 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 June 30, 2016, the Company concluded that realization of deferred tax assets beyond June 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 GmbH on April 1, 2016, the Company acquired intangible assets of approximately €6,640,000. Because the amortization of these intangible assets is not deductible under German tax law, the Company recorded deferred tax liabilities of approximately €1,972,000 (approximately $2,190,000) as of June 30, 2016. Additionally, the Company was able to retain net operating losses of approximately €2,669,000. Accordingly, the Company recorded deferred tax assets of approximately €793,000 (approximately $880,000) as of June 30, 2016. The fiscal years ended December 31, 2012, 2013, 2014 and 2015 are subject to examination by U.S. federal, state and Sweden taxing authorities.
