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, 2012, the Company estimated its U.S. GAAP effective tax rate to be approximately 31% for the year ending December 31, 2012. This rate includes 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 is 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 includes additional tax expense of $15.9 million resulting from other tax adjustments. These other tax adjustments include $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 Company is not required to provide U.S. federal or state income taxes on cumulative undistributed earnings of foreign subsidiaries when such earnings are considered permanently reinvested. At December 31, 2011, the Company considered most of its foreign unremitted earnings to be permanently reinvested. The Company's policy is to evaluate this assertion on a quarterly basis. During the second quarter of 2012, the Company changed the assertion for some of its foreign subsidiaries to provide management additional financial flexibility. At September 30, 2011, the Company estimated its U.S. GAAP effective tax rate to be approximately 24% for the year ending December 31, 2011. This rate included $11.0 million of additional tax expense associated with the Company's patent infringement settlement and a tax benefit of $6.2 million resulting from other tax adjustments. These other tax adjustments related to a change in state corporate income tax legislation as well as an adjustment of the Company's tax accounts as a result of the closure of certain tax audits. 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. The estimated annual effective tax rate for 2012 is higher than the annual effective tax rate for 2011 primarily due to the Company's projected increased profitability in higher taxed jurisdictions and the items discussed above.

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, 2012, the Company estimated its U.S. GAAP effective tax rate to be approximately 31% for the year ending December 31, 2012. This rate includes net tax expense of $3.5 million associated with the loss from disposal activities and restructuring expense recorded during the third quarter of 2012.
