MARKET ANNOUNCEMENT


Sadia is once again selected to be part of Bovespa´s Corporate Sustainability Index (ISE)


For the second year consecutively, Sadia S.A. has been selected for BOVESPA´s Corporate Sustainability Index (ISE), effective from December 2008 till November 2009. This version of ISE congregates 38 companies compromised with sustainable development. The market value of the new portfolio is R$372 billion, 30.7% of Bovespa´s total capital on November 21, 2008.


The companies chosen to comprise the new index were selected among 51 companies that answered to the questionnaire developed by the “Sustainability Studies Center” (GVCes) of Escola de Administração de Empresas de São Paulo, Fundação Getúlio Vargas (“Business Administration School”, FGV-EAESP). The questionnaire was sent to 137 different companies, whose stocks correspond to the 150 with greatest liquidity among all the stock in BMF&BOVESPA.


The Corporate Sustainability Index (ISE) was created based on the international concept of the triple bottom line (TBL). It evaluates, in an integrated way, environmental, social and financial elements, as well as corporate governance indicators and general characteristics and nature of the products. The index reflects a portfolio of companies with the best practices in the three dimensions that measure sustainability and highlights them as references to the socially responsible investment and as inducers of sustainability practices in the Brazilian corporate environment.


Sadia´s every process is currently incorporating the concept of sustainability. Besides the Corporate Sustainability Index (ISE), Sadia´s shares are part of the Bovespa Index (Ibovespa), the Index of Shares with Differentiated Corporate Governance (IGC) and the Index of Shares with Tag-Along Rights (ITAG).
