Canada-based funding agency Caisse de Dépôt et Placement du Québec (CDPQ) is said to be in talks with the GMR Group to buy a 25-30 per cent equity stake in Hyderabad airport, in a deal valued $350 million-$400 million. The Abu Dhabi Investment Authority has also been in talks to buy a minority stake in the airport. Credit Suisse has been appointed lead arranger for the stake sale programme.
