The group, formed from the merger of Janus Capital and Henderson Global Investors on 30 May, announced a total net outflow of $1bn (£767m) in the second quarter, on a pro forma basis, down from $7bn in the first quarter.
Assets under management increased 4% to $345bn, buoyed by positive equity flows, a “moderation” in quantitative equity outflows and foreign currency translation gains.
Additionally, the group recorded $57m of net cost synergies largely because of reducing the combined headcount following the merger.
It is anticipated that this saving will increase to at least $85m by the end of the first 12 months since the merger closed – and to at least $110m of recurring annual pre-tax synergies within three years of the merger.
Elsewhere, the group, co-headed by Andrew Formica (pictured) and Dick Weil, reported second quarter 2017 net income of $41.7m, or $0.28 per diluted share, down slightly from $42.6m, or $0.38 per diluted share, for the first quarter.
In terms of investment performance, as at 30 June 2017, 69%, 71% and 89% of its AUM outperformed the benchmark on a one, three and five-year basis, respectively.
