Brazilian supermarket chain Companhia Brasileira de Distribuicao (CBD), or CBD, said Tuesday that same-store sales in the first four months of the year rose 8.6% for food products and 11.1% for non-food products.

In the first four months, net sales stood at 6.40 billion reals ($3.14 billion), up 13.9% on the year before, the company said in its first quarter earnings statement.

CBD said the growth was due to a successful commercial strategy, which included aggressive promotions.

CBD is jointly controlled by the Diniz family of Sao Paulo, the chain's founders, and by French retail company Casino Guichard Perrachon SA (CO.FR). Its main competitors in Brazil include U.S. retail giant Wal-Mart Stores Inc. (WMT) and France's Carrefour SA (CA.FR).
