In January 2012, Wynn's former business partner Kazuo Okada filed suit to gain access to company documents related to Wynn's pledge to donate $135 million to the University of Macau Development Foundation. Wynn later accused Okada's company, Aruze, of violating the Foreign Corrupt Practices Act, leading to a Department of Justice probe into Aruze's gifts of hotel rooms and other expenses to Philippine, South Korean, and Japanese gaming officials. In a March 2013 U.S. Securities and Exchange Commission (SEC) filing, Wynn noted that while the Okada dispute could cut into Wynn's profits, beyond an "informal" SEC inquiry into the Macau donation, there was no formal investigation underway. In July 2013, the SEC announced that its investigation into the Macau donations was concluded and it would not pursue any enforcement action against Wynn or Wynn Resorts.
