The DFM said that trading in Shuaa shares would be suspended until the investment bank issued a statement disclosing its convertible bonds.

Last year Shuaa issued a AED1.5bn ($408m) convertible bond to Dubai Banking Group. It was scheduled to be converted to equity, giving them a 32 per cent stake in the company, on 31 October. However, this did not occur as scheduled.

The suspension of its shares caps a torrid month for Shuaa, during which it has been fined AED3.4m for manipulating the share price of DP World, and then posted a loss of AED37.1m for the first half of 2008 because of the downturn in global financial markets and exposure to failed US investment bank Lehman Brothers.
