On behalf of the Italian Association of Toll Motorway and Tunnel Concessionaires, Brattle experts provided support on granting an extension of concessions by the Italian government and the European Commission. Our work entailed support on the economic and financial analysis, drafting financial plans, and participating in meetings with the stakeholders. We analyzed the different types of investments and the compensation scheme adopted to ensure their correct remuneration in the face of tariff increases capped over the years. We also examined the remuneration required – both for investments identified in existing concessions and for new investments – on the basis of the historical reconstruction of the dynamics of the concessionaires’ revenues, and the cost orientation of forecasted prices consistent with investments.
