Old Mutual eyes further African expansion as sales dip Mr Roberts said the company has no plans to sell more of its stake in Old Mutual Asset Management, which raised £317m through a stock market float of 20pc of its equity in New York last month. Old Mutual, which shifted its main stock market listing from Johannesburg to London in 1999, has also bolstered its wealth management business after agreeing to buy Quilter Cheviot from Bridgepoint for £585m last month. The deal is set to complete next year after getting regulatory clearance. Old Mutual Global Investors, which hired star manager Richard Buxton from Schroders last year, managed £18.4bn at the end of September, up from £17bn three months ago, on flat gross sales of £2bn. The overall wealth business managed £82.2bn, up from £80.3bn.
