Income Tax Examination, Description	The Company files income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. The Company is no longer subject to U.S. federal income tax examinations by tax authorities for tax years before 2007, or for the 2010 tax year. The Company is no longer subject to China income tax examinations by tax authorities for tax years before 2005. With respect to state and local jurisdictions and countries outside of the U.S. (other than China), with limited exceptions, the Company is no longer subject to income tax audits for years before 2006. Although the outcome of tax audits is always uncertain, the Company believes that adequate amounts of tax, interest and penalties, if any, have been provided for in the Company’s reserve for any adjustments that may result from tax audits. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in interest expense.
