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, 2011, the Company's effective tax rate is estimated to be 23.6%, which includes $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. This rate differs 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 items, including equity in affiliates' earnings. The Company's effective tax rate in the third quarter of 2010 was estimated to be 3.6%, which included a favorable impact of $21.2 million from the reversal of the Company's valuation allowance on U.S. based foreign tax credit carryforwards. At September 30, 2010, the Company's projected annual effective tax rate for 2010 was estimated to be 17.3%, which included the impact of the reversal of the Company's valuation allowance on U.S. based foreign tax credit carryforwards, the impact of the change in tax legislation related to Medicare Part D subsidies of $2.5 million, the additional tax expense associated with the BERU - Eichenauer equity investment gain and the tax benefit associated with the Company's environmental litigation settlement. In addition to the impact of the items noted above, the estimated annual effective tax rate for 2011 is higher than the estimated annual effective tax rate for 2010 primarily due to the Company's increased profitability in higher taxed jurisdictions.
