F&C Management, the UK investment group, has doubled new asset wins in the first half of 2004 and stemmed client losses ahead of its £750m (€1.12bn) merger with Isis Asset Management in October.

The firm, being sold by Dutch insurer Eureko, has released preliminary financial results ahead of the merger, which is "on track", for early October, according to a spokeswoman. It will create the UK's fourth largest asset manager with around £120m in assets. The combined group will take a stock market listing later this year.
