In a going concern (i.e. non receivership) scenario, is the amount needed to "retire" the Sr pref the $194bn currently on b/s or the higher liquidation preference (220bn+) which still builds under the letter agreements? the bloomberg article cited the latter but I view it as the former (outside of receivership). If I'm correct then the letter agreements are not an accounting gimmick but rather actual capital raised, once again assuming they are going concerns.
