The board also has redeemed 24 million shares of Wynn Resorts owned by Aruze USA, of which Okada is the principal shareholder. Based on Friday's closing level of $112.69, those shares have a market value of $2.7 billion. But Wynn Resorts is compensating Okada with significantly less. The company said it will pay him $1.9 billion in 10 years. The payment is in line with Wynn's articles of incorporation, the release said. The news release also said that Wynn on Saturday filed a lawsuit against Okada and his company's Aruze USA and Universal Entertainment Corp. in Nevada District Court for breach of fiduciary duty and related offenses. Wynn Resorts operates high-end casinos in Las Vegas and Macau, China. It's not the only U.S. casino company to be troubled with probes into potential overseas bribery.
