MarketWatch:
June 15, 2010: NYSE
informs the conservator, Federal Housing Finance Agency, that Fannie Mae and Freddie Mac no longer are qualified.
June 16, 2010: Delisting order goes out. Actual transition to the U.S. OTCBB is scheduled for July 8, 2010. (Yes, the pink sheets. The virtual exchange where you have to up-front acknowledge the stocks' illiquidity before purchasing.)
Of course, if they weren't parastatal corporations they'd have been delisted for
negative total equity long before now:
First things first. Fannie and Freddie aren’t real companies. The total equity in the two companies is a negative $146.9 billion, according to Bose George, an equity analyst covering the mortgage and housing sectors for Keefe, Bruyette & Woods. In short, these are government-owned zombie entities that would have been shut down by regulators long ago, if the regulators didn’t own them.
