Our effective tax benefit rate remained relatively consistent at approximately 36% for the three months ended March 31, 2014 compared to approximately 35% for the three months ended March 31, 2013.

We file income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions.  Tax years remaining subject to examination in these major jurisdictions include 2010 to present.
