PARIS (Bloomberg) ? Axa SA, Europe?s second-largest insurer, said its 7.9 billion-euro ($9.9 billion) purchase of Credit Suisse Group?s Winterthur unit is ?running quickly and smoothly?.

The Paris-based insurer still expects the acquisition to be completed by year-end, it said in a presentation on its website yesterday. Axa will prepare a three-year business plan for Winterthur by year-end and still hasn?t ?taken into account? higher revenue from the purchase.

The insurer also said it already has ?started to deliver? on its 2012 targets.

Chief executive officer Henri de Castries a year ago announced targets for the insurer to double revenue and triple earnings, excluding investment swings and merger-related costs, by 2012.

The purchase of Winterthur will give the insurer a leading position in the Swiss insurance market and an additional 13 million clients in 17 countries from Spain to China.
