"It is absolutely perfect timing because the market has come down 35 percent," then Asia Securities chief executive Asanga Seneviratne told LBO in January 2006.

The Bloomberg report said Auerbach's firm traded in risky markets including Gaza and was trying to open Libya for foreign investors in March.
"By providing access to capital where it is needed most, Auerbach is an agent of development for the connected age," the report quoted author Parag Khanna as saying in a 2011 book.
His firm has large stakes in several Sri Lanka firms.
Auerbach Grayson is the third largest shareholder of Ceylon Tobbacco and is among the top 20 in NDB Bank, the top holder of non-voting Ceylinco Insurance shares and the sixth largest non-voting shareholder in Seylan Bank.
