ATHENS (Reuters) - Greece's privatisation agency said on Tuesday it had asked for an improved offer from private shareholders in Athens International Airport (AIA) to extend their concession for operating the nation's largest airport by 20 years until 2046.
German-based airport manager AviAlliance and Greek group Copelouzos, which have a 45 percent stake and a concession to run the airport until 2026, submitted a financial offer for the 20-year extension, privatisation agency HRADF said.
"HRADF’s board of directors, after reviewing the offer, asked AIA’s management for the submission of an improved offer," the agency said in a statement without giving further details.
The initial concession for the private firms to run the airport was awarded in July 1995.
HRADF holds a 30 percent stake in the airport, while the government has a 25 percent stake.
Under a third bailout signed with the European Union and the International Monetary Fund in 2015, Greece promised to renew the agreement with the private shareholders.
