Lawsuits shine light on Goldman’s role in Asiasons, Blumont and LionGold crash

[yeokiwi]

Another question that comes to mind is that since a substantial amt of shares were bought under margin acct in IB how did Quah Su-Ling still manage to pledged another big chunk with GS.

Eh...according to the first post of this thread
Quah initially pledged three million Asiasons shares as collateral for the credit facility.

So...
Quah pledged her shares with GS to gain access the credit facility.
Using the money from GS and put into IB, she bought more BAL using margin acct.

That may be the reason why GS was so fast in reacting since it probably could piece all the information together.
As for IB, they probably did not know that the money that was deposited into the margin account came from a loan.
