Empresa Distribuidora Sur Sociedad Anonima announced earnings results for the six months ended June 30, 2012. For the period, operating revenues were CLP 165,014 million against CLP 139,425 million for the same period a year ago. Gross operating loss (LBITDA) was CLP 17,225 million against CLP 905 million for the same period a year ago. Operating loss was CLP 25,054 million against CLP 8,232 million for the same period a year ago. The negative evolution of the company results are consequence of increased operating costs derived from the country's inflation rate, without the corresponding tariff increases because of the delay in fulfilling certain clauses of the Minutes of Agreement executed with the National Government of Argentina, especially the semi-annual recognition of tariff adjustments incorporated into the Cost Monitoring Mechanism and the implementation of an Integral Tariff Review as provided in such Minutes, all of which is heavily impacting the company's financial balance.
