The head of casino giant MGM Resorts International says he’ll step down soon as the company finds a successor. Jim Murren has led the company since 2008. A corporate statement Wednesday said he intends to leave before his contract expires next year, but gave no reason. Publicly traded MGM Resorts has some 80,000 employees at 29 casinos and hotels worldwide. The company is the largest employer in Nevada and owns several Las Vegas Strip properties, but recently sold its Bellagio, MGM Grand and Mandalay Bay resorts in a leaseback agreement with Blackstone Group.
