Henderson Group has announced a new lineup of managers for its combined UK fund range following the completion of its acquisition of New Star Asset Management.

The former New Star fund managers who are transferring to Henderson’s London office today include Richard Pease, Guy de Blonay, Nick Sheridan, James Gledhill, Roger Dossett, Mark Harris, Craig Heron, Trevor Green and Simon Rowe – all of whom continue to manage the same funds as they did at New Star.

For other New Star funds, a Henderson fund manager has been appointed to provide greater potential for improving the investment performance for investors in those funds, the firm said in a statement. There will be no change to the managers of Henderson funds.

Mark Skinner, previously director of retail fund sales and marketing at New Star, will lead the UK retail business at Henderson.

Following the acquisition, the sales and marketing teams of Henderson and New Star have been merged. As the next stage in the firms' amalgamation, the brand integration of the UK retail business under the Henderson New Star brand is scheduled for late May.

“We are delighted to have reached this stage so quickly after announcing the deal just nine weeks ago… For investors in New Star funds they need no longer worry about New Star’s financial position or further corporate uncertainty. For existing Henderson clients the addition of talented fund managers boosts our existing investment teams and provides new viewpoints, skills and expertise,” said Andrew Formica, chief executive of Henderson Group.

Henderson has £49.5 billion (around $73 billion) in assets under management, as at 31 December 2008, and employs around 840 people worldwide.
