IMO...the only good thing for Equity Escrow Marker Holders, in regards to the long waiting time, is that whatever recoveries are received, profits for shareholders would be considered Long Term Capital Gains.
But if your Escrow Markers are in Roth IRAs...you're sitting pretty. I have a brother that has all of his Escrow Markers in a Roth IRA...and he'll be very happy when (IMO...not if) recoveries start flooding his account.
