Income Taxes	11. Income Taxes Effective tax rates for continuing operations were 7.3% and 15.9% for the three and six months ended June 30, 2013, respectively. These rates were impacted by net discrete items, principally the conclusion of certain U.S. federal tax audits, as well as certain state and international tax audits, and the effect of the American Tax Relief Act of 2012 signed into law on January 2, 2013, totaling $61,477 and $66,002 of favorable net discrete items for the three and six months ended June 30, 2013, respectively.

Excluding these discrete items, the comparable effective tax rates were 26.7% and 27.2% for the three and six months ended June 30, 2013, respectively and 26.8% and 27.3% for the comparable 2012 periods.
