It is NEVER allowable to keep any material transaction “mum” for a publicly traded company.
This was an asset sale in a liquidation, obviously.
The requirements you speak of to operate the assets are for a transaction type that was simply not reported here. In that type of transaction, they keep nothing material “mum”, obviously, but they do have to demonstrate that they actually want the assets and not just the write off.
In this case, the write off is worth less than the outstanding debt…
Less Than, it is truly over.
