The decrease in the company's tax expense for the six months ended June 30, 2013 relative to the prior year resulted primarily from the jurisdictional mix of pre-tax earnings and net discrete items, principally the effect of the American Tax Relief Act of 2012 signed into law on January 2, 2013, reserve releases related to statute of limitations expirations, a favorable audit settlement, and the effective settlement of other state uncertain tax benefits. The effective tax rate varies from the U.S. federal statutory rate of 35% due to results of foreign operations that are subject to income taxes at different statutory rates and certain jurisdictions where the company cannot recognize tax benefits on current losses.

All of the company’s unrecognized tax benefits as of June 30, 2013, if recognized, would impact the effective tax rate. During the next twelve months, it is reasonably possible that federal, state and foreign tax audit resolutions could reduce unrecognized tax benefits and income tax expense by up to $6.9 million, either because the company’s tax positions are sustained on audit or settled, or the applicable statute of limitations closes.
