The Company’s effective tax rates for the three months ended June 30, 2015 and 2014 were (33.8)% and 29.7%, respectively.   The Company’s effective tax rates for the nine months ended June 30, 2015 and 2014 were (34.6)% and 31.8%, respectively. The lower effective tax rates for each of the periods ended June 30, 2014 primarily resulted from a manufacturers’/producers’ deduction available to U.S. manufacturers.
