Croatia's transport ministry has received only one compliant bid for the privatisation of Zagreb airport, from a consortium including France's Aeroports de Paris and Bouygues.
The other bid, from the operator of Zurich airport and Strabag, was "not read", said the ministry because it did not contain numerical data requested by the tender documents.
It added that the valid bid will centre on a 30-year concession, with a fixed fee of €87.2 million ($115 million) plus a larger variable fee calculated as a percentage of revenues.
The French bid is of "extremely high quality", said the ministry.
Privatisation of Zagreb airport will include the construction of a new passenger terminal as well as management of the current infrastructure.
