ATTD financed its past operations by issuing convertible notes (i.e., a form of loan with investment "interest") to private parties in exchange for operations $$$. Much like bonds or CDs, convertible notes mature and ATTD then owes the private parties the $$$ ATTD initially borrowed PLUS a set amount above that as a profit to the note holder and payment by ATTD for borrowing their money.
Okay, now when ATTD's convertible note holders' notes mature, they "cash them in" typically by working with a broker who sells the requisite portion of authorized stocks shares into the outstanding shares to acquire the $$$ due and owing the matured convertible note holders. The SEC allows brokers the freedom to report such three-way security sale transactions at the end of the trading day, rather than right in the middle of trying to sell A/S shares for the highest price possible (i.e., to pay the note holders and yet still minimize dilution of the O/S).
I hope that makes sense.
