The effective tax rates for the three months ended March 31, 2015 and 2014 were 24.3% and 29.9%, respectively. The decrease in the effective tax rate was due primarily to the mix of earnings between jurisdictions with differing tax rates.  The effective tax rates for the six months ended March 31, of 2015 and 2014 were 25.4% and 31.0%, respectively.  The decrease in the effective tax rate was due primarily to the enactment of the research and development credit for calendar year 2014 in the first fiscal quarter of 2015 and the mix of earnings between jurisdictions with differing tax rates.  The Company believes it is reasonably possible that $946 of unrecognized tax benefits will be realized in the coming year.
