The Atlantic supermarket chain has begun selling off parts of its network in a bid to raise cash, after recently filing for protection from its creditors. Atlantic, which employs about 3,700 people, admitted last month to becoming one of the food sector’s larger victims of the recession as it sought help to manage its debts. The company said in a bourse filing yesterday that it has sold off two branches in Thessaloniki and is looking into the sale of additional stores to reduce debts and raise cash. No financial details were provided. Atlantic has a branch network of around 130 stores.
