The list is available (in Greek only) at the site of the Ministry of Finance and it contains data available to the Ministry up to 5 September 2011 (and some corrections that were made until 15 September 2011).
It is remarkable that a number of state owned or state controlled companies are in this list and in some cases very high up in the list. Some characteristic cases include the Greek Railway Company, the Shipyards of Syros and Elefsina, the Organization for the Restructuring of Undertakings and Olympic Airways. All the above state owned or state controlled companies, except Railways, are currently in liquidation.
