Our effective tax rate for the three months ended March 31, 2013 and 2012 was 37.9% and 38.5%, respectively. Our effective tax rate for the six months ended March 31, 2013 and 2012was 38.1% and 38.6%, respectively. The decrease was primarily due to a lower international enacted tax rate in the U.K.

With few exceptions, we are no longer subject to income tax examination for years before 2008 in the U.S. and significant state and local jurisdictions. We are no longer subject to income tax examination for years before 2010 in significant foreign jurisdictions.
