Insurer AXA will foot most of the bill for the reconstruction of the roof of Charles de Gaulle airport in Paris following its collapse last year.
Pierre Graff, chairman of Aeroports de Paris (ADP), this week estimated the total cost of repairs at €150m (£100m).
A spokesman at AXA said: "We can confirm that we are the primary insurers in this case. The total cost of the reconstruction to us will emerge over the next few months."
The roof of terminal 2E at France"s main international airport collapsed in May 2004, killing four people and injuring several more.
