Glencore said on July 3 it had been subpoenaed for documents relating to its business in the three countries since 2007, sending its shares down 13 percent and leaving investors guessing about the direction of the investigation. The Switzerland-based firm had said the subpoena related to compliance with the U.S. Foreign Corrupt Practices Act and money-laundering statutes but did not indicate the Department of Justice was focused on intermediaries or give further details. Glencore, which said on July 11 it would cooperate with the U.S. authorities after receiving the subpoena, declined to offer additional comment for this article. The Department of Justice declined to comment.
