(REUTERS) - Sony Corp has tapped Morgan Stanley and Citigroup to help sound out options for its entertainment business, according to a media report.
Cable television network CNBC reported on Thursday that Sony has hired the two banks but that the process was still in an exploratory stage. CNBC cited an unnamed source.
Morgan Stanley, Citigroup and Sony declined to comment.
Billionaire hedge fund investor Daniel Loeb has called on Sony to spin off its lucrative United States-based entertainment arm, which includes one of Hollywood's top film studios and a leading music label.
Mr Loeb said his Third Point hedge fund had accumulated a little more than 6 per cent of Sony's shares, a stake worth US$1.1 billion (S$1.4 billion), making Third Point the largest stakeholder in the company that invented the Walkman portable music player and Trinitron TV.
Asked about Mr Loeb's proposal at the AllThingsD conference in Rancho Palos Verdes, California, Sony's chief executive Kazuo Hirai said: "We need to give it serious consideration and come to a decision and move on."
