contrarian bull,
Since you have understood the concepts, this is to provide you and others with more details.
1. This is how it works when Tsy invests $187.5B in FnF:
The invested cash of $187.5B becomes assets for FnF and in return, FnF issue SPS worth $187B to Tsy. So this cash assets of $187.5B is balanced by SPS liability of $187.5B in book keeping.
2. If original SPSPA agreement were to be used:
All the $286B payments will go for paying off SPS libility of $187.5B and 10% Dividend and that would result in zero SPS liability. In this scheme, the accounting entries would have reduced both liability of SPS+interest and assets by $286B. But there is no theft of FnF capital.
3. Under NWS:
$286B was paid as dividend (no 10% interest) without reducing SPS liability of $187.5B. In this scheme, only assets are reduced without corresponding reduction in SPS liability. Currently FnF have net worth of $600M. That means SPS liability of $187.5B has corresponding assets of $187.5B. If today FnF were to be liquidated then Tsy gets $187.5B and JPS/CS get $600M.
4. If NWS were to be revoked retroactively:
$286B would be added back to assets resulting in networth of ($0.6B + $286B + $187.5B) with SPS liability of ($187.5B + 10% interest). Then $286B can be used to pay off SPS liability of ($187.5B + 10% interest). This results in networth of $188.1B ($0.6B + $187.5B).
5. If NWS were to be revoked proactively:
FnF can pay off SPS liability of $187.5B with corresponding assets of $187.5B maintaining current net worth of $600M. In this case, NWS would steal net capital of $187.5B from FnF. After this FnF will have to raise $150B to $200B capital from markets to meet regulatory requirements.
