Kolkota: United Bank of India (UBI) has got the approval from Reserve Bank of India (RBI) to launch initial public offering (IPO), which will reduce the government stake in the bank by 16 percent. S C Gupta, Chairman and Managing Director (MD), UBI said, "The bank would file the offer document for the same by November-end and the issue is likely to hit the market by January. RBI gave clearance for the IPO without any changes and the proposal has been forwarded to the government. We expect to receive the government approval in the next 10-15 days." The central government has approved the bank's capital restructuring plan, which will reduce its paid-up capital from 1,532 crore to 266 crore. The balance 1,266 crore will be shifted to the capital reserve account of the bank. The bank plans to issue 50 million shares of 10 each at a premium. The bank has also asked for 800 crore from the government to maintain an eight percent Tier-I and overall 12 percent capital adequacy ratio (CAR) bY 2012, in keeping with the government advice to public sector banks. This is in addition to 800 crore already approved by the government for the bank. In March this year, the government had contributed 250 crore as Tier-I capital at UBI, by subscribing to perpetual non-cumulative preference shares (PNCPS) at repo plus 100 basis points. Of the 800 crore already approved, the bank expects to get the remaining 550 crore as Tier-I capital by December 2009. The CAR of the bank will be more than 13 per cent after the capital infusion. Gupta said that UBI was open to acquire a smaller bank after the IPO. It is also planning to set up a housing finance subsidiary. UBI is also planning to open a representative office in Bangladesh shortly.
