Over at the D & O Diary, Kevin M. LaCroix has been keeping track of all the ERISA lawsuits filed in connection with sub-prime lending (which you can access here).
He also writes about the litigation stemming from the most recent economic turmoil here:
The economic crisis that began as the subprime meltdown has clearly entered a dark new phase. And just as the prior stages of the crisis generated waves of related litigation, this new phase already has produced its own distinctive round of lawsuits. Like the underlying economic circumstances, the new litigation phase also seems darker and more threatening. . .
