The effective tax rate for the six months ended June 29, 2013 was 24.1% versus 28.7% for the six months ended June 30, 2012. The change in the second quarter effective rate was primarily driven by completion of the tax integration of the EPC acquisition and a prior year benefit attributable to qualification in China for a tax incentive, compared to second quarter 2012. The change in the six month effective rate was driven by the same factors as for the second quarter as well as the by the 2012 research and development retroactive reinstatement which was recorded in the first quarter of 2013. The lower effective rate as compared to the 35.0% statutory Federal income tax rate is driven by lower foreign tax rates.
