MGM Resorts International Chairman and CEO Jim Murren sold more than $22 million shares of the company’s stock over two days last week, according to a filing with the Securities and Exchange Commission. The transactions came a little more than a week after Murren, 58, announced he would depart from the positions he held since 2008 before his employment agreement expired at the end of next year. MGM’s board is conducting a search for a replacement.
