An ex-compliance officer of Goldman, Sachs & Co. was charged by the Securities and Exchange Commission with trading on confidential inside information he was entrusted to use for internal surveillance purposes, not for proprietary gain. According to the SEC, from July to October 2015, Yue Han was employed by GSCO as an associate in its Surveillance Analytics Group within the company’s compliance department. In connection with at least four companies GSCO advised on mergers and acquisitions, Mr. Han traded for his own account or that of an apparent relative in China based on information he accessed as a result of his position with the firm, said the SEC. In October 2015, before this case was filed, Mr. Han left GSCO and the United States and is believed now to be in Shanghai. The SEC seeks an asset freeze, an injunction, disgorgement and a fine against Mr. Han, as well as Wei Han, the apparent relative whose account Mr. Han traded for.
