Three public sector banks (PSBs) \u2014Punjab National Bank (PNB), Andhra Bank and United Bank of India (UBI) \u2014 have put non-performing assets (NPAs) worth Rs 4,441 crore up for sale as the 15-day deadline to resolve such accounts comes closer. As per the Reserve Bank of India\u2019s (RBI) February 12 circular, NPA accounts in which banks have an exposure of Rs 2,000 crore or more must be referred to the insolvency courts unless they were resolved by August 27. The circular gives banks another 15 days to move to the court. PNB has put on sale 21 accounts with an outstanding of Rs 1,320 crore, of which the largest are Moser Baer Solar, with an outstanding of Rs 233 crore, Divine Alloys & Power Co (Rs 201 crore) and Divine Vidyut (Rs 133 crore). Bids have been invited on both cash basis and as a mix of cash and security receipts (SRs) for most accounts. Seven of them are being offered on a 100% cash basis. The reserve prices put out by PNB suggest that it is willing to take a haircut of up to 92% in at least one account \u2014 Birla Surya \u2014 which is being offered only on a full-cash basis. For the three largest accounts on sale, the haircuts could range between 5% and 66%.
