I think one of the cleanest settlements would be to deem PSPA repaid so that gets wiped. Then the 30B in overpayments used to exchange for all of the warrants.
That way zero monetary changes actually occur. The govt can save some face too.
Its really not bad at all... If commons current have 40B in capital and we can increase our equity by 79.9% by spending 30B... Pretty good if you ask me.
