Some executives from The Cosmopolitan of Las Vegas have left for new jobs, just over a week after MGM Resorts International took over operations of The Cosmopolitan.

MGM closed on the deal to acquire The Cosmopolitan from the Blackstone Group for $1.625 billion on May 17, after being approved by regulators in the previous weeks. MGM executives had told regulators they could expect some shuffling of jobs once the transaction was completed.

Niklas “Nik” Rytterstrom will assume the role of general manager for The Cosmopolitan. The former president and chief operating officer of The Mirage is replacing Patrick Nichols. He will report to CityCenter President and Chief Operating Officer Anton Nikodemus.
