Subsequent Events [Abstract]
Subsequent Events	Note 20. Subsequent Events On February 23, 2015, the Board of Directors announced that, pursuant to an anonymous whistleblower complaint, our Audit Committee has conducted an investigation of certain potential related-party transactions involving Davis Zhang, our President, China Operations. The investigation did not conclude that there was any intentional misconduct by Mr. Zhang, or that he received any improper benefit from these transactions. Further, the investigation did not reveal any inaccuracies in our financial statements resulting from these transactions. However, the investigation identified certain historical related-party transactions that were not previously disclosed in our filings with the Securities and Exchange Commission. We have filed a Current Report on Form 8-K on February 23, 2015 to disclose such historical related-party transactions. On February 20, 2015, the Board waived any potential inconsistencies with our Code of Conduct and Ethics arising from the transactions identified in the investigation. Also, the Audit Committee approved the related-party nature of such transactions to the extent it had not previously approved such transactions. The Board and Audit Committee specified that such waiver and approval would have retroactive effect to the date of commencement of the transactions covered by such waiver and approval. We expect to incur additional professional services expense related to the investigation of approximately $1.2 million in the first quarter of 2015.
