Note 13.  Income Taxes

The effective tax rate for the three months ended December 31, 2012 and 2011 was 33.4% and 35.3%, respectively.  The decrease in the effective tax rate is due to a reduction in foreign taxes and the availability of foreign tax credits during the three month period ended December 31, 2012.

The effective tax rate for the six months ended December 31, 2012 and 2011 was 34.2% and 34.8%, respectively.  The decrease in the effective tax rate is due to a reduction in foreign taxes and the availability of foreign tax credits during the six month period ended December 31, 2012, partially offset by the expiration of certain statutes of limitation during the six month period ended December 31, 2011.
