The effective rate for the three months ended March 31, 2013 differs from the U.S. statutory tax rate primarily as a result of no tax benefit being realized on foreign net operating losses. The effective tax rate for the three months ended March 31, 2012 differs from the U.S. statutory tax rate as a result of no tax benefit being realized on foreign net operating losses as well as the recording of a valuation allowance against previously recognized foreign deferred tax assets related to net operating loss carryforwards. Due to the various jurisdictions in which the Company files tax returns and the uncertainty regarding the timing of the settlement of tax audits, it is possible that there could be significant changes in the amount of unrecognized tax benefits in 2013 but the amount cannot be estimated.
