The increase for the latest quarter came from $16 billion in market gains, according to the firm's third-quarter earnings release.
The money manager reported $4.4 billion in net outflows for the quarter, compared to $2.8 billion the previous quarter and $15.4 billion in the third quarter of 2011.
AllianceBernstein's retail offerings accounted for $5 billion in net inflows, which were offset by net outflows of $7.7 billion in institutional business and $1.7 billion in private client business.
In a news release, the firm attributed the institutional outflows to the loss of an institutional value client and the completion of the liquidation of the firm's Public-Private Investment Program fund.
Net revenues for the third quarter totaled $708.2 million, up 10.3% from the previous quarter and 10.4% higher than the year before.
The firm reported a net loss of $48.2 million in the third quarter. The loss was attributed primarily to a $168 million non-cash real estate charge associated with the firm's real estate consolidation plan. The firm had reported net income of $72.9 million in the second quarter and $72.5 million in the third quarter of 2011.
Spokesman Jonathan Freedman could not be immediately reached for comment.
