The increase in the effective tax rate when comparing the three months ended March 31, 2012 to the three months ended March 31, 2011 was primarily due to research and development tax credits not being extended in 2012, partially offset by a tax benefit related to the impairment of certain intangible assets. The Company’s effective tax rate generally differs from the U.S. federal statutory rate of 35% due primarily to lower tax rates on earnings generated by the Company’s foreign operations that are taxed primarily in Switzerland.
