The number of leveraged buyout deals in France worth more than €500m ($634m) has quadrupled in one year, prompting private equity managers to review their strategies to avoid battling over increasingly coveted deals.

According to LBO Net, a survey of the market created by Barclays Private Equity France, 10 deals of €500m-plus including debt were recorded in the first six months of this year, four times more than in the same period last year.
