UK - Henderson shareholders have voted overwhelmingly in favour of the acquisition of Gartmore, with 99.97% giving the go-ahead.
At a general meeting this morning, voters were near unanimous on the £360m deal.
This follows yesterday's meeting with Gartmore shareholders where 99% also voted in favour of the takeover terms.
In today's meeting 432,114,176 votes were cast for the deal compared to 97,157, which were against.
Ahead of the poll, Henderson chairman Rupert Pennant-Rea pointed to improved operating margins, a stronger fund range and a wider distribution network as reasons for the acquisition to go ahead.
In terms of operating margins, Pennant-Rea says "substantial synergies" can be extracted from combining Gartmore with Henderson.
"Even on prudent assumptions about assets under management, we do not expect the operating margin to be less than 50%. As such, we should be able to move our combined operating margin to 35%, with a medium term aim of closer to 40%."
He also adds Gartmore's retail capabilties in the UK equity and absolute return space will fill gaps in the Henderson range as well as global and emerging market equities.
On distribution, he says: "We already have good distribution in the UK, US and Europe. However, this acquisition will extend our distribution network into other areas such as Japan, and enhance our global hedge distribution."
Henderson initially tabled an offer for Gartmore in December before announcing the proposed acquisition in January.
Earlier this month, 14 key managers, repersenting 84% of Gartmore's AUM, signed to move to Henderson while seven managers were given the axe.
According to Henderson's predicted timescales, any changes to the fund range will be complete by the summer.
