Brooks Macdonald's assets under management moved towards the £13 billion mark in the third quarter.
According to a trading update, the wealth firm saw a 3% increase in AuM over the period, lifting assets to £12.8 billion. For comparison, the MSCI WMA Private Investor Balanced Index increased by 1% over the period.
Brooks attributed the increase to a combination of a £158 million inflow and £211 million in investment performance.
Within this, Brooks said its UK investment management business maintained a 'healthy rate of organic growth' as assets in the division rose 3.6% to £11.1 billion.
However, its Channel Islands-based international investment management arm, BMI, experienced net outflows following the departure of one of its client-facing teams. Funds under management in this unit fell 1.1% to £1.7 billion.
'We have maintained positive momentum in our UK business over the first quarter, with good organic growth despite softer client sentiment in light of the current macroeconomic environment,' Brooks chief executive Caroline Connellan (pictured) said in a statement.
'The ongoing strength of our investment performance has been particularly pleasing, driven by our centralised investment process and the expertise within our teams.'
