AXA Rosenberg Investment Management's assets under management dropped 40% during the quarter ended June 30, to $37 billion, according to the firm's website.
For June, AUM declined by 10%, while leading domestic and international benchmark indexes were dropping by 4% to 5%.
The latest figures might be a sign that the pace of outflows is slowing. Outflows spiked from mid-April, after the firm's leadership told clients and consultants that key research executives had failed to properly inform them about a coding error discovered in June 2009, and fixed by November.
The firm has since announced some key departures, including that of co-founder Barr Rosenberg, and organizational changes aimed at ensuring greater oversight.
An AXA Rosenberg spokesman declined to comment on the latest AUM figures.
