For the three months ended June 30, 2014, we had an effective tax benefit rate of 36.5% compared to 33.3% for the three months ended June 30, 2013. The increase in the effective rate of benefit was primarily due to the smaller base of pretax loss for the 2014 period in relation to certain items for which we currently are not able to recognize a tax benefit. 
 
Our effective tax benefit rate remained relatively consistent at 35.6% for the six months ended June 30, 2014 compared to approximately 34.4% for the six months ended June 30, 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.
