Review of the EU Regulation (of the European Parliament and of the Council No. 717/2007/EC) on roaming charges in the mobile telecommunications sector could adversely affect our results of operation.
The EU roaming regulation effective from June 30, 2007 sets a limit on international wholesale mobile roaming voice charges (Eurotariff). See "Item 4Regulation and Pricing". Text messaging and data communications are not covered at present, but are subject to regulatory monitoring. This regulation will negatively influence the roaming revenues of our mobile operations.
