Significant Change in Unrecognized Tax Benefits, Nature of Event	The total amount of unrecognized tax benefits that, if recognized, would affect our effective tax rate was approximately $19 million at December 31, 2014. It is reasonably possible that the amount of the unrecognized benefit with respect to certain of our unrecognized tax positions will significantly increase or decrease within the next 12 months.
Significant Change in Unrecognized Tax Benefits is Reasonably Possible, Estimated Range Not Possible	These changes may be the result of settlements of ongoing audits or competent authority proceedings. At this time, an estimate of the range of the reasonably possible outcomes cannot be made.
Unrecognized tax benefits	$ 19,488,000	$ 20,710,000	$ 14,591,000	$ 10,177,000
Income Tax Examination, Description	We file income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. We are no longer subject to U.S. federal income tax examinations by tax authorities for tax years before 2007, or for the 2010 tax year. We are no longer subject to China income tax examinations by tax authorities for tax years before 2004. With respect to state and local jurisdictions and countries outside of the U.S., with limited exceptions, we are no longer subject to income tax audits for years before 2011. Although the outcome of tax audits is always uncertain, we believe that adequate amounts of tax, interest and penalties, if any, have been provided for in our reserve for any adjustments that may result from future tax audits. We recognize accrued interest and penalties, if any, related to unrecognized tax benefits in interest expense. We had an immaterial amount of accrued interest and penalties at December 31, 2014, 2013 and 2012.
