Your escrow is yours and cannot be sold or traded, regardless of holdings in WMIH.
They are 2 separate entities now.
One a stolen financial institution, the term "failed" is used, however stolen and orchestrated by the Bid winner, regulator, receiver and federal government is the truth and fact.
One is a holding company post bk that has 200m in cash, no debt or liabilities,and billions of tax advantages for years to come.
Escrow can be left to an heir. Consult a legal advisor or attorney.
IMO
Have a Blessed Day!
