The deal, which saw a stake in the luxury operator be sold to the US-based group for an undisclosed sum, will see long-time chief executive Paul Cleary and his UK management team retain control of the day-to-day running of the company.
Speaking to TTG, Cleary said the two companies have "an almost identical" product profile, and the joint venture has been "years in the making".
"We thought there was an opportunity for us to be stronger together, and for them to bring what they have to the table and for us to do the same," he said.
