I think Walrath's 10B comment was not meant to be an accurate number by any means.
I think she was just trying to hint that there was indeed money under seal, i.e. safe harbor. It could be less but it likely is much more.
It was like she couldn't contain herself and she had to say something. She knows the angst that's out there among retailers, some who have lost their life savings, homes, spouses, health, etc. She could've just as easily said, look, there will be no further money so people shouldn't get their hopes up. But she didn't.
I find it hard to believe that she, Rosen, and others involved are so cold and cruel that they care nothing about those whose lives have been so profoundly devastated.
