The Company is also required to record the tax impact of certain unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, in the interim period in which they occur. In addition, jurisdictions with a projected loss for the year where no tax benefit can be recognized are excluded from the estimated annual effective tax rate.

The effective tax rate for the three and nine months ended September 30, 2013 was 18% and 27%, respectively. The effective tax rate for the three and nine months ended September 30, 2012 was 34% and (42%), respectively, which included a benefit of ($19,500) included in the estimated annual effective tax rate resulting from forecasted net income in the U.S. with no corresponding tax expense due to utilization of valuation allowances and a benefit of ($48,300) resulting from changes in determinations relating to the potential realization of deferred tax assets and the resulting reversal of a valuation allowance on net deferred tax assets in the United States.
