If all of the Secured Creditors are being PAID IN FULL under the POR then I doubt that they are keen on Fraudulent Conveyance Litigation - which will drain funds from the Estate.
I think that any WIN Secured Creditors which also hold Unsecured Bonds will be open to a FC Lawsuit.
The UCs are getting aggressive now in their push to start litigation against UNITI. I get the clear impression that they think they have more than enough evidence to win any Litigation against UNITI.
