Federal Bank is open to acquiring any bank with a balance sheet size of Rs 1000-Rs 2000 crore, its general manager, Thomas Joseph C said. However, the bank is yet to identify any. ?We are keen in north or west-based banks and prefer an inorganic route,? he said. The bank’s capital base is expected to touch Rs 4,000 crore by the end of this financial year. Joseph said the bank was keenly looking out for value buy in Uttar Pradesh, Maharashtra, Gujarat or Punjab.
