Belgrade Nikola Tesla Airport's concession process will take part in two phases, the "Večernje novosti" daily reports. During the first phase, interested subjects will make non-binding offers and sign a confidentiality agreement with the government. Following an assessment of their bids, those with the best offers will be invited to take part in the second phase where binding bids will have to be submitted. The Serbian government is interested in concluding a 25-year concession agreement for the airport rather than an all-out privatisation. A concession would bring a one-off payment of up to 400 million euros, plus an annual fee of eleven million euros to the state. The airport's privatisation advisor will decide on the most suitable sale model within the next two months.
