Art. 168. Duration of the concession

1. The duration of concessions shall be limited in the contract notice by the contracting authority or the contracting entity depending on the works or services required to the concessionaire. The same is commensurate to the value of the concession, as well as to the organizational complexity of the same.

2. For concessions lasting more than five years, the maximum duration of the concession shall not exceed the period that is reasonably necessary to the concessionaire to recoup the investments, together with a return on invested capital, taking into account the investments required to achieve the specific contractual objectives as resulting from the economic-financial plan. The investments taken into account for the purposes of the calculation shall include those actually supported by the concessionaire, both initial investments and investments during the life of the concession.
