The firm’s European SICAVs range, its open-ended collective investment scheme, has also experienced net inflows of £480 million. Meanwhile, its US mutual fund range also experienced good net inflows with the global equity income fund in particular performing well. 

The retail inflow figures were an encouraging result since they include outflows of £40 million from the loss of two investment trust mandates.

“I am pleased with the performance of our retail funds, especially our SICAV funds, which recorded strong positive net flows as investor sentiment improved over the quarter in both Europe and Asia,” Andrew Formica, Henderson Group's chief executive, said.

Henderson has also gone on a spending spree, acquiring a 33 percent stake in 90 West Asset Management, an Australia-based global natural resources investment management firm.

“They made a formal offer for their shares [the minority shareholders] at a certain level and that is how they acquired the majority of their shares,” David Whitten, executive chairman and portfolio manager at 90 West Asset told InvestorWeekly. 

As part of the deal, which occurred last month, Henderson will take a position on the board and inject some working capital.  

Henderson had “a placement into 90 West which has provided a little bit more working capital, which has assisted us grow our business and build up our team,” Mr Whitten added. 

The deal also included a global distribution agreement between the two firms: “We are very fortunate to be involved with them... our product will certainly be strengthened by the Henderson marketing and distribution capability,” Mr Whitten said.

The acquisition follows Henderson's hire late last year of a credit specialist team based in Philadelphia and the purchase of a 50 per cent interest in US hedge fund Northern Pines Capital.
