As a result, Shivers Investments, LLC is now wholly owned by Holding, and both MCC and Shivers Investments, LLC are "brother-sister" subsidiaries of Holding. Shivers Investments, LLC directly owns 28,309,674 shares of Class A Common Stock of Mediacom Communications Company. After this transaction, MCC no longer beneficially owns these securities, although the ultimate beneficial ownership of these securities has not changed, since each of STO, Holding, Shivers Investments, LLC and MCC are still controlled by William S. Morris and his wife. Craig S. Mitchell- Senior Vice President-Finance 2007-07-06
