Abu Dhabi state investor Mubadala has halted talks to buy Abraaj's investment business, two sources said, in a blow to the private equity firm which is facing an investigation by investors into how it used some of their money.
Dubai-based Abraaj, which denies any wrongdoing, is considering selling some or all of the unit following a row with four investors, including the Bill & Melinda Gates Foundation and the World Bank's International Finance Corporation, over how it used their money in a $1 billion healthcare fund.
Mubadala, which has more than $200 billion in assets, and Abraaj held initial talks a month ago, but these did not progress, one of the sources told Reuters.
Abraaj said it does not comment on market speculation, while Mubadala declined to comment on Monday.
"We remain focused on working collaboratively with our investors and continuing to execute on the re-organization of our firm to pave the way for continued long-term growth and value creation," Abraaj said in an email to Reuters.
Investment banks have also approached international private equity firms to look at Abraaj's investment arm, but some are holding off until after an investigation by forensic accounting experts Ankura Consulting, which has been commissioned by the investors, two other sources said.
Other potential buyers include Abu Dhabi Financial Group (ADFG), sources told Reuters last month.
ADFG, which manages $6.5 billion in assets, declined to comment about its interest in Abraaj's investment business. The Gates Foundation and the IFC, the World Bank's private finance arm, have both declined to comment on the row.
