Income Taxes The Company’s effective tax rate could fluctuate significantly on a quarterly basis and could be negatively affected to the extent earnings are lower in the countries in which it operates that have a lower statutory rate or higher in the countries in which it operates that have a higher statutory rate or to the extent it has losses sustained in countries where the future utilization of losses are uncertain. The Company’s effective tax rate could also fluctuate due to changes in the valuation of its deferred tax assets or liabilities, or by changes in tax laws, regulations, accounting principles, or interpretations thereof. In addition, the Company is occasionally subject to examination of its income tax returns by tax authorities in the jurisdictions it operates. The Company regularly assesses the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of its provision for income taxes. The effective tax rate for the three months ended March 31, 2013 was a benefit of 53.0%. The earnings of the Company’s foreign entities for the three months ended March 31, 2013 was $8.9 million. The tax rates in the foreign jurisdictions in which the Company operates are less than the Company’s domestic rate, therefore, losses in the foreign jurisdictions will have a negative impact on the Company’s effective tax rate, while earnings in the foreign jurisdictions will have a positive impact on the Company’s effective tax rate. The effective tax rate for the three months ended March 31, 2013 was positively impacted by foreign profits taxed at lower rates and a domestic loss taxed at a high rate as well as recognition of $1.4 million tax benefit as a result of implementing the 2012 American Taxpayer Relief Act. The effective tax rate for the three months ended March 31, 2013 was negatively impacted by acquisition related expenses that are not deductible for tax purposes as well as an increase in the valuation allowance against foreign tax credits as a result of the acquisition of ORCC. The effective tax rate for the three months ended March 31, 2012 was a benefit of 23.3%. The earnings of the Company’s foreign entities for the three months ended March 31, 2012 was $9.7 million. The tax rates in the foreign jurisdictions in which the Company operates are less than the Company’s domestic rate, therefore, losses in the foreign jurisdictions will have a negative impact on the Company’s effective tax rate, while earnings in the foreign jurisdictions will have a positive impact on the Company’s effective tax rate. The effective tax rate for the three months ended March 31, 2012 was positively impacted by foreign profits taxed at lower rates and a domestic loss taxed at a high rate. The effective tax rate for the three months ended March 31, 2012 was negatively impacted by S1 acquisition related expenses that are not deductible for tax purposes. The amount of unrecognized tax benefits for uncertain tax positions was $15.0 million as of March 31, 2013 and $13.1 million as of December 31, 2012, excluding related liabilities for interest and penalties of $2.0 million and $1.8 million as of March 31, 2013 and December 31, 2012, respectively. The amount of unrecognized tax benefits for uncertain tax positions increased by $1.5 million and $0.4 million during the quarter ended March 31, 2013 for the uncertain tax positions of ORCC and PTESA, respectively, which were included in the preliminary purchase price allocation. The Company believes it is reasonably possible that the total amount of unrecognized tax benefits will decrease within the next 12 months by approximately $1.4 million, due to the settlement of various audits and the expiration of statutes of limitation.
