Margin Call during the speculative period. In the long run when the deal is officially confirmed the $2 is even expensive for JPM.
You could use options and thus have no margin call risk. Yet the options are not implying a long-term price of $2. The January 2010 $15 calls for example sold for $2.50 today. The Jan 2009 $10 puts sold for $5.90 on decent size. If it's definitely going to $2 then that's $2 of free money.
