You are correct about the figures being $80B and not $800B. However, on the other issue concerning what JPMC owes, is another matter. When it comes to how much JPMC owes, the Purchase and Assumption Agreement says they owe book value for the assets ; as well as the Global Settlement Agreement between WMI, JPMC and the FDIC. So, there are two official documents, both signed by JPMC, which stipulates that they are to pay "Book Value" for the assets of WMB. My math may be weak, at 80 years of age. However my reading is still very good.
