It's a Form D, required to be filed in connection

It's a Form D, required to be filed in connection with an unregistered (i.e., exempt) issuance of securities within 15 days of the first issuance. In this case, the Form D is for the recent Series C preferred stock the company previously 8K'd. This is not new stock or further dilution (beyond what has already been 8K'd), this is just a housekeeping filing required by SEC rules.
