One of the reports, carried by financial newspaper Calcalist, said the deal could close as early as this week and that Apax would pay a 37 percent premium. Syneron has a market capitalisation of $366 million.

A spokesman for Apax in Israel would not comment on the report, and officials at Syneron were not reachable for comment.

Syneron says its products have a range of applications, like body contouring, hair removal and wrinkle reduction. The products are sold under two brands, Syneron and Candela.

The two companies were reported in February to have entered negotiations.
