One of the Katanga board members was Glencore major shareholder Telis Mistakidis, a former employee whose stock options made him a billionaire in the IPO. Glencore, which had effectively taken over Katanga, agreed to vote for the joint venture. The loan document specifically provided that repayment would be owed if agreement was not reached within three months. Gertler and Glencore each have denied wrongdoing. Appleby had worked for Glencore and its founder Marc Rich on major projects in the past, even after his indictment in 1983. Rich was indicted in the United States on federal charges of tax evasion and making controversial oil deals with Iran during the Iran hostage crisis. He received a controversial presidential pardon from U.S. President Bill Clinton on 20 January 2001, Clinton's last day in office.
