Consolidation of Local Service Areas
In March 2007, Cofetel issued a resolution to eliminate 70 local service areas and in September 2008, it issued a resolution to eliminate an additional 125 local service areas, reducing the total number of local service areas from 397 to 202 in a process that began in November 2008 and will be completed in 2010. If implemented as issued, the resolution would have the effect of requiring mobile operators to reassign the local area code numbers for a significant number of their subscribers. We are currently in discussions with Cofetel for a technical solution to the reassignment of local area codes as a result of the consolidation. As of the date of this annual report, we have not reached an agreement with Cofetel regarding this matter. We do not expect the consolidation of local service areas to have a significant negative impact on our results of operations.
