SAO PAULO May 13 (Reuters) - First-quarter net profit at Grupo Pao de Acucar (CBD.N)(PCAR4.SA), Brazil's biggest diversified retailer, fell 35 percent as the incorporation of appliance chain Casas Bahia boosted expenses.
The company on Friday posted net income of 110.85 million reais ($68.4 million), compared with 170.4 million reais in the same period of 2010.
Five analysts polled by Reuters forecast, on average, net profit of 133 million reais, excluding the Nova Globex appliance unit.
Last year the Sao Paulo-based company merged its Globex unit with former rival Casas Bahia to form Brazil's biggest home appliance chain.
Net revenue for the group rose 56 percent to 10.869 billion reais.
