It is shares "outstanding", the press release is correct. Shares authorized are not shares "issued", only shares outstanding are shares issued.
No worries though, everyone is aware that the buyback of 2% of the outstanding shares was taking place and we are now aware that it will be complete by this Friday.
No problems, just weakness until the next significant even. It's just a matter of time.
Hopefully it means that there were buying back 2% of the Authorized shares from the outstanding shares. So that would mean that they're buying back 1 billion shares are being removed 9 billion outstanding? Maybe?
