To estimate the value of the concession contract, the concession-granting authority takes into account in particular :
1° The value of any form of option and any extensions to the term of the concession contract;
2° Revenues collected from users of the facilities or services, other than those collected on behalf of the concession granting authority or other persons;
3° Payments made by the concession granting authority or any other public authority or any financial advantage granted by any of them to the concessionaire;
4° The value of subsidies or any other financial advantage granted by third parties for the operation of the concession;
5° The proceeds from any sale of assets forming part of the concession;
6° The value of all supplies and services made available to the concessionaire by the conceding authority, provided that they are necessary for the execution of the works or the provision of the services;
7° Any premiums or payments to candidates or tenderers.
