I'm pretty sure, that Prefs Shareholders which did not at least file some Lawsuits until 2011 as within 3 Years, will not get the Dividends paid for 10 Years, if any and just continue to pay Dividends for from the moment when the Company is released !
So maybe new Lawsuits will come but they always can defend by mentioning that under the Gov conservation It was out of their control and doing Lawsuits against the Gov . . . . . .
The Companies could not withstand To Pay Dividends To Everybody For 10 Years.
This is an extraordinary situation which requests extraordinary measurements and that could means they cancel all Prefs to protect themselves !
