OSI Systems, a U.S. company that develops and markets security and inspection systems, announced that the Department of Justice and Securities and Exchange Commission have informed the company that they have closed their respective investigations into possible violations of the Foreign Corrupt Practices Act. OSI Systems did not provide any further details in announcing the closing of the investigations.

As Compliance Week previously reported, the launch of the investigations followed a 2017 report conducted by short seller Muddy Waters, claiming OSI Systems “obtained a major turnkey contract in Albania through corruption.” In a securities filing at the time, OSI Systems said the SEC and Department of Justice were investigating “trading in the company’s securities and have subpoenaed information regarding trading by executives, directors, and employees, as well as company operations and disclosures in and around the time of certain trades.”

The Muddy Waters report prompted a class-action complaint filed in December 2017 in the U.S. District Court for the Central District of California alleging that OSI Systems. As stated in the complaint, “defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts about the company’s business, operations, and prospects” concerning the contract in Albania. A federal judge in May, however, dismissed those claims, finding that OSI’s securities filings didn’t qualify as misstatements under U.S. securities law or contain illegal omissions.
