Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our effective income tax rates were 28.6% and 33.4% for the six and three months ended June 30, 2013 and 35.0% and 33.1% for the same periods in the prior year. The effective tax rate for the six months ended June 30, 2013 is lower than the comparable prior year period primarily due to the inclusion of U.S. research and development tax credits in 2013 which were not available in 2012. On January 2, 2013, President Obama signed into law the American Taxpayer Relief Act of 2012 that retroactively renewed the research and development tax credit for 2012 and extended the credit through December 31, 2013. As tax law changes are recognized in the period in which new legislation is enacted, the 2012 R&D credit of $145 was recorded in the first quarter of 2013. Federal income tax audits have been settled for all years prior to 2007. The years 2009-2010 are currently being examined by the IRS, and we have filed appeals with the IRS for tax years 2007-2008. We are also subject to examination in major state and international jurisdictions for the 2001-2012 tax years. We believe appropriate provisions for all outstanding tax issues have been made for all jurisdictions and all open years. Audit outcomes and the timing of audit settlements are subject to significant uncertainty. It is reasonably possible that within the next 12 months we will resolve the matters presently under consideration for the 2007-2008 tax years with the IRS.

Our effective income tax rates were 28.6% and 33.4% for the six and three months ended June 30, 2013 and 35.0% and 33.1% for the same periods in the prior year. The effective tax rate for the six months ended June 30, 2013 is lower than the comparable prior year period primarily due to the inclusion of U.S. research and development tax credits in 2013 which were not available in 2012.
