Since 5/30, after the stock was conveniently marked at its 52 week high on month end for May 2008, CSX has fallen -7.1% from $69.06. Deutsche Asset Management and 3G Capital were the 2 other recipients in the top 3 holders of this wonderfully ironic month end performance result.

It's likely that the entire nature of the Total Return Swap business will change dramatically with this ruling as regulators and banks realign their perceptions of the product.
