Revenues for the fourth quarter of 2010 were $778m, compared to $782m in the same period a year-ago.
Operating Income in the fourth quarter of 2010 was $154m, down 23% compared to $200m in the same period a year ago.
Assets under management totaled $478bn, down from $496bn a year earlier.
Total net outflows were $29.3bn, higher than the $16.8bn in the year-earlier quarter.
AllianceBernstein chairman and CEO Peter Kraus said 2010 marked significant progress in the continued growth of AllianceBernstein, with improvement in gross sales, increased average AUM, higher adjusted margins and positive financial results on many fronts.
"In the fourth quarter we outperformed benchmarks and peers in most of our equity and fixed income services. However, we did see acceleration in outflows, concentrated for the most part in equity mandates in the Institutions channel.
"We are confident that we will extend our track record of outperformance in equities in the months ahead, which, combined with an improved risk appetite on the part of investors, should lead to an improvement in flows," Kraus said.
