13. Income Taxes

The United States statutory tax rate for the three months ended December 31, 2014 and 2013 was 35%.  The Company’s effective tax rates for the three months ended December 31, 2014 and 2013 were 35.5% and 31.9%, respectively.   The lower effective tax rate for the period ended December 31, 2013 primarily resulted from a manufacturers’/producers’ deduction available to U.S. manufacturers.
