NEW YORK (Reuters) - Blackstone Group LP
The New York-based firm's economic net income (ENI) per unit for the three months through September was 76 cents, compared to the mean forecast for 74 cents, according to Thomson Reuters I/B/E/S. A year earlier, Blackstone reported ENI per share of 68 cents.
ENI reflects the mark-to-market valuation gains or losses on Blackstone's portfolio and is a closely watched earnings metric for U.S. private equity firms.
In premarket trading, Blackstone shares were flat.
Stock market swings often impact the valuation of private equity firms' holdings because they mark many of their holdings to market. The benchmark S&P 500 index <.SXP> rose 7.2 percent in the third quarter.
Blackstone also benefited from a 19.9 percent appreciation of Gates Industrial Corporation
"Assets under management increased 18 percent versus the prior year, bringing the total to a new record of $457 billion," Chairman and Chief Executive Steve Schwarzman said in a statement.
Distributable earnings -- the actual cash available for paying dividends -- were $769 million, up from $626 million a year ago. Blackstone said it would pay shareholders a quarterly distribution of 64 cents per common unit, including a 10 cent special distribution.
