 State Concessions
The increase of average toll tariffs of the Autovias, Intervias and Vianorte concessionaires is explained by the contractual
adjustment based on the IGP-M. At Centrovias, despite the contract adjustment, average toll tariff dropped 41.2% due to
the fact that toll collection switched to bidirectional (both side directions) in four plazas, and toll tariff were reduced by
50%.
 Federal Concessions
In the months of December 2010 and February 2011, the toll tariffs charged by federal concessionaires were adjusted
according to (i) the criterion for rounding the first decimal place, and the cumulative variation of the IPCA in the 12 months
prior to adjustments. The result of this adjustment increased the average tariff applied by federal concessionaires, which rose
from R$ 1.51 to R$ 1.66 (+9.7%).
