Financial crisis litigation has been going on for several years now and has been resulting in lots of piecemeal settlements. As a result, it's easy to miss the big picture. There's actually been quite a lot of settlements covering a fair amount of money. (Not all of it is real money, of course, but the notionals add up).
By my counting, there have been some $94.6 billion in settlements announced or proposed to date dealing with mortgages and MBS.
