Income Taxes	8. Income Taxes For the three and six months ended June 30, 2012, the effective tax rates for continuing operations before consideration of discrete items were relatively flat as compared with the prior year periods. The pre-discrete tax rate was 27.4% and 27.1% for the respective three and six months ended June 30, 2012, and 27.2% for each of the comparable three and six month periods of 2011. Net discrete items of $(372) for the second quarter and $1,060 year to date did not significantly impact the 2012 effective tax rates. Discrete items totaling $22,338 in the second quarter of last year and $30,354 in the first half of last year reduced 2011 effective tax rates to 19.7% and 21.4%, respectively, for the comparable three and six month reporting periods. The unfavorable impact of increased U.S. earnings mix in the 2012 periods was more than offset by the favorable impact of lower effective tax rates in foreign jurisdictions neutralizing rates on a comparative year over year, pre-discrete basis. The Company believes uncertain tax positions could be settled within the next twelve months, for which an estimate cannot currently be made due to the uncertainties associated with the resolution of these matters.
