Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's provision for income taxes is based upon an estimated annual tax rate for the year applied to federal, state and foreign income. On a quarterly basis, the annual effective tax rate is adjusted, as appropriate, based upon changed facts and circumstances, if any, as compared to those forecasted at the beginning of the fiscal year and each interim period thereafter. At September 30, 2013, the Company estimates its U.S. GAAP effective tax rate to be approximately 26% for the year ending December 31, 2013, which includes tax benefits of $3.8 million and $2.1 million related to the program termination agreement and retirement related obligations discussed in the Other (Income) Expense footnote. This rate also includes a net tax benefit of $7.3 million, which is comprised of tax benefits of $6.6 million related to the extension of the federal research and development credit and other international tax provisions resulting from the retroactive impact of U.S. legislation enacted in January 2013, $3.1 million related to 2012 provision to return adjustments and $2.5 million related to the reversal of certain deferred tax asset valuation allowances, partially offset by a $4.9 million tax expense related to a comprehensive income adjustment. At September 30, 2012, the Company estimated its U.S. GAAP effective tax rate to be approximately 31% for the year ending December 31, 2012. This rate included net tax expense of $3.5 million associated with the loss from disposal activities and restructuring expense recorded during the third quarter of 2012. The $3.5 million net expense was comprised of $11.2 million tax expense resulting from the completion of the disposal, partially offset by a tax benefit of $7.7 million associated with the restructuring expense. For the nine months ended September 30, 2012, the net tax benefit associated with the loss from disposal activities and restructuring expense was $2.0 million. The 31% U.S. GAAP effective tax rate also included additional tax expense of $15.9 million resulting from other tax adjustments. These other tax adjustments included $8.2 million of tax expense primarily resulting from the settlement of certain tax audits and $7.7 million of tax expense associated with the Company's second quarter 2012 decision to change its cash repatriation assertion for some of its foreign subsidiaries. The annual effective tax rates differ from the U.S. statutory rate primarily due to foreign rates which differ from those in the U.S., the realization of certain business tax credits, including foreign tax credits, and favorable permanent differences between book and tax treatment for certain items, including equity in affiliates' earnings.

Income Taxes

The Company's provision for income taxes is based upon an estimated annual tax rate for the year applied to federal, state and foreign income. On a quarterly basis, the annual effective tax rate is adjusted, as appropriate, based upon changed facts and circumstances, if any, as compared to those forecasted at the beginning of the fiscal year and each interim period thereafter.

At September 30, 2013, the Company estimates its U.S. GAAP effective tax rate to be approximately 26% for the year ending December 31, 2013, which includes tax benefits of $3.8 million and $2.1 million related to the program termination agreement and retirement related obligations discussed in the Other (Income) Expense footnote. This rate also includes a net tax benefit of $7.3 million, which is comprised of tax benefits of $6.6 million related to the extension of the federal research and development credit and other international tax provisions resulting from the retroactive impact of U.S. legislation enacted in January 2013, $3.1 million related to 2012 provision to return adjustments and $2.5 million related to the reversal of certain deferred tax asset valuation allowances, partially offset by a $4.9 million tax expense related to a comprehensive income adjustment.

At September 30, 2012, the Company estimated its U.S. GAAP effective tax rate to be approximately 31% for the year ending December 31, 2012. This rate included net tax expense of $3.5 million associated with the loss from disposal activities and restructuring expense recorded during the third quarter of 2012. The $3.5 million net expense was comprised of $11.2 million tax expense resulting from the completion of the disposal, partially offset by a tax benefit of $7.7 million associated with the restructuring expense. For the nine months ended September 30, 2012, the net tax benefit associated with the loss from disposal activities and restructuring expense was $2.0 million. The 31% U.S. GAAP effective tax rate also included additional tax expense of $15.9 million resulting from other tax adjustments.
