Henderson Global Investors has made a series of changes to the management of its range of multi-manager funds following its acquisition of UK-based investment management firm Gartmore earlier this year.

Bill McQuaker, Henderson’s head of multi-manager and deputy head of equities, will manage the Henderson Multi-Manager Income & Growth Fund and the Henderson Multi-Manager Distribution Fund with Chris Forgan. McQuaker will also manage the Henderson Multi-Manager Managed Fund with Tony Lanning, and the Henderson Multi-Manager Active Fund with Helen Bradshaw. The Gartmore Multi-Manager Absolute Return Fund will be managed by Tony Lanning and Paul Craig.

Henderson is also proposing to merge some of Gartmore’s multi-manager funds into existing Henderson multi-manager vehicles, subject to unit holder and regulatory approval.

The firm wants to merge the Gartmore Multi-Manager Active Fund into the Henderson Multi-Manager Active Fund, the Gartmore Multi-Manager Balanced Fund into Henderson Multi-Manager Managed Fund, and the Gartmore Multi-Manager Cautious Fund into Henderson Multi-Manager Income & Growth Fund, all effective from 12 August 2011.

“The proposed mergers of the Active, Balanced and Cautious Gartmore funds further streamlines our fund range and leaves us with a clear proposition across the risk spectrum,” said McQuaker.

Henderson’s multi-manager team manages more than £2.5 billion ($4.1 billion) in retail assets, as at 31 March 2011.
