From the WSJ, 10/31:
The downfall of MF Global has led one investment bank to disclose its exposure to the now bankrupt futures and commodities brokerage. In a short statement, Jefferies says its exposure to MF’s debt securities is less than $9 million in marked-to-market positions, which it says “resulted from facilitating client orders as part of normal-course market making.”
No word on what led to the disclosure, but investors are keeping a watchful eye on such comments from banks as MF Global was brought down in part by the fallout of bad bets on European sovereign debt.
