Andhra Bank, which has lent Rs 300 crore to microfinance companies, is yet to hear from the troubled sector on restructuring of loans offered to them, a top bank official said Monday. ?We have not got any request on loan restructuring. As such we have not seen any defaults in our microfinance loan portfolio,? Anil Girotra, executive director of Andhra Bank said.The lender, however, is yet to commence fresh lending to microfinance institutions. ?No further lending has taken place. If there is a proposal, we will examine it,? he said.
