Income Taxes

Our effective tax rate decreased to 32.8% for the three months ended March 31, 2015 from 33.8% for the three months ended March 31, 2014. The decrease is primarily due to a legal entity restructuring of our European operations.  As a result of the reorganization, a certain portion of the not indefinitely reinvested foreign earnings in the affected countries are subject to lower effective tax rates.

At March 31, 2015, our unrecognized tax benefits were $134.7 million. Of this amount, approximately $57.1 million would affect our effective tax rate upon resolution of the uncertain tax positions.
