Istithmar Said to Halt Investment; Dubai Weighs Sale (Update1)

Istithmar World, the Dubai sovereign wealth fund, is halting investments as part of a restructuring effort after spending more than $25 billion this decade on stakes ranging from a yacht marina to luxury retailer Barneys New York, according to people familiar with the plan.

The process may result in a sale of the fund or its assets, they said. Istithmar, run by David Jackson, said this week that co-chief investment officers John Amato and Felix Herlihy would leave the firm. Jackson’s job is under review, the people said.

A restructuring by Istithmar and its parent Dubai World may mark the most public reversal of fortune for a state-controlled investment firm since global credit markets seized up in 2007. Sovereign wealth funds, fueled in part by oil revenue, have become sources of capital around the world for companies including Citigroup Inc. and Morgan Stanley.
