That's not how damages work. Those damaged by the Warrants would only be entitled to the $ loss of their shares.
So if FNMA goes from $3.50 to $2.50 after the Warrants are exercised, the Damages would be capped at $1 per share. If FNMA goes up, then no one was damaged :-(
But that court case will never be heard anyway. It will be tossed out by every judge it's put in front of.
