So what? I'd expect the need for the key employees has at least been significantly reduced since the sale of the company failed, and it could be they don't have a need for anyone from the old company to rack the books up.
And of course all of the bids during the process of SISP and the asset liquidation were sealed/NDA'd, that's quite a normal process. Now tht the sale is concluded, we now know what was offered and accepted.
