2008 guidance revision taking into account:
Revenues – On-net calls pattern increase for the market as a whole and higher handset sale through direct channels - both events
ended up pressuring incoming and handset revenues
Expenses – Anticipating the investments to capture mobile broadband outstanding growth and number portability opportunity;
Reinforcing the call-center services, strengthening loyalty program to high-end clients and enhancing 3G network capacity.
Based on the aforementioned scenario, we are taking a more conservative position on top line and EBITDA margin
