The worthless stock thing has been in countless filings and is more than likely in relation to the "WORTHLESS STOCK" they own in WMB and how they can use it as a deduction.
"Conclusions relate to availability and timing of a worthless stock deduction."
We can review the timing... Do I really need to go back into countless other filings with similar content to show you this has been something that's been ongoing for a year and nothing new? regardless of what you are insinuating is somehow "timely"?
I know you've seen similar language in oodles of the docs before so I don't know why all of the sudden you feel it's timely, nor do I care.
They're prepping the tax returns and looking at using the loss of the value of their WMB stock as a deduction.
