A flotation price range of 250p-300p has been set for the initial public offering of a specialist credit investor, BlueBay Asset Management. BlueBay has also announced that Lehman Brothers is planning to buy a 4.99 per cent stake from the float’s managers Credit Suisse for a price of around £28.4 million. Lehman has agreed to hold the shares for a year after the IPO and will not build a stake of more than 9.99 per cent of the company. BlueBay was formed in 2001 and had at the time taken advantage of the boom in bond markets. The company now has around $8 billion under management.
