Janus Henderson, the fund management group, is on track to achieve an ambitious $125m cost-saving target almost 18 months ahead of schedule — but investor withdrawals from its funds rose sharply.

The company reported net outflows of $4.3bn for the three months to the end of September, in its third-quarter results on November 1. That was up from the $2.7bn in net outflows recorded in the previous quarter. Assets under management rose slightly, to $378.1bn, in line with market movements.
