PHILADELPHIA - CVC Capital Partners failed to repay a loan owed to Chuo Mitsui Capital Co and lost its stake in restaurant chain Skylark Co, The Nikkei reported in its Friday morning edition.

The Chuo Mitsui Trust Holdings (8309.T) group's private-equity unit took possession of CVC's Skylark stake in mid-August, Nikkei reported.

CVC became Skylark's second-largest shareholder in 2006, investing roughly 60 billion yen as part of a management buyout for the family restaurant operator, Nikkei reported. CVC most recently held a 20.9 percent stake in Skylark, according to the report.

CVC could not be immediately reached for comment.
