Hi FOFreddie,
The SEC Filings are legally binding, that's what the SEC is for.
( As Seen by the used Formulations, made by Attorneys. )
The FHFA Fact Sheets more like "To Do Lists", not so legally binding as The SEC Filings.
The mentioned "Shareholders will retain all their rights as determined by the market.", where the market does only determine The PPS, nothing else and this is now the only remaining since The Gov not decided to have The Stocks Halted, but to let the "Empty-Shells Stocks" trade for better impressions as only at OTC possible under this conditions!
( It's a kind of Impression Fooling the Gov mastered as we All know. )
