Fortress Investment Group, the listed private equity and hedge fund group, has suspended redemptions at its flagship Drawbridge Global Macro Fund after investors sought to withdraw more than $3.5bn in funds, according to a regulatory filing Wednesday, reports the FT. Fortress, which had $8bn under management in September, took the action, at least in part, as it must keep minimum level of assets or risk having to unwind derivatives trades. Fortress shares closed down 25% at $1.87 in New York. It has lost about 88% of its value this year and now has a market cap of about $773m. In its SEC filing, Fortress estimated that the Drawbridge fund would have assets of $3.65bn by Jan 1. Meanwhile, Bloomberg reports, DE Shaw & Co, the investment firm run by David Shaw, and Farallon Capital Management have limited withdrawals by clients, joining more than 80 hedge-fund managers to impose restrictions in the past two months.
