Note 14.  Income Taxes

The effective tax rate for the three months ended September 30, 2012 and 2011 was 35.0% and 34.1%, respectively.  The increase in the effective tax rate is due to the favorable resolution of certain tax matters and the expiration of certain statutes of limitation during the three month period ended September 30, 2011.
