Income Taxes	Income Taxes The effective tax rates for the three months ended December 31, 2016 and January 2, 2016 were 17.6% and 26.6%, respectively. The effective tax rate for the three months ended December 31, 2016 is lower than would be expected by applying the U.S. federal statutory tax rate to earnings before income taxes primarily from the tax benefits associated with selling our European space businesses. The effective tax rate for the three months ended January 2, 2016 is lower than would be expected by applying the U.S. federal statutory tax rate to earnings before income taxes primarily due to a significant portion of our earnings that come from foreign operations with lower tax rates and included the benefit from the enactment of legislation reinstating the research and development tax credit in the U.S.
