NSAV Holding Inc (NSAV)

Share buybacks have to be publicly announced in advance. SEC rules. Obviously, a share buyback is news shareholders would find attractive, which is why it must be announced publicly.
They have to list several things - how many shares they may buy, over what time, and at what price or price range. The SEC has a more complete list, I just haven't looked at it for a couple years.
Obviously, they must also have cash, which NSAV does not have. You can't buy shares with borrowed money that will be paid back by diluting shares...
