KP Singh is hoping to do what Anil Ambani failed to do at the beginning of the year and that is a buyback in the hope that it will shore up their stock prices. DLF's buyback will be at a maximum price of Rs 600 rupees per share for a maximum of 2.2 crore shares and the company will not spend more than Rs 1,100 crore. The offer will be valid for 12 months from the day of Sebi approval.
