São Paulo, January 15, 2013 – arteris S.A. (Novo Mercado BM&FBovespa: ARTR3) announces to the market the 2012 tolled traffic for its state and federal concessionaires, reflecting the total vehicle-equivalent registered in its toll plazas throughout the period. The numbers are preliminary, unaudited and subject to revision.

Note: The vehicle-equivalent unit is used as the basis for the collection of toll tariffs. A passenger vehicle is considered a vehicle-equivalent and a commercial vehicle (truck or bus) is computed by the number of axles possessed, which are each counted as one passenger vehicle. A passenger vehicle is equivalent to one commercial vehicle axis.
