Total Access Communication Public Company Limited

Total Access Communication Public Company Limited or DTAC is one of the leading telecommunication services providers in Thailand. Founded in August 1989, it operates 800 MHz and 1800 MHz frequency bands under a concession granted by the Communications Authority of Thailand (CAT). As of 6 September 2007, the Company's registered capital was Baht 4,744,161,260 of which Baht 4,735,622,000 was paid-up capital and divided into 2,367,811,000 ordinary shares with a par value of Baht 2.

To promote the development of telecommunication services in Thailand, the private sector was allowed to participate in the telecommunication market under concessions on a Build-Transfer-Operate (BTO) basis with two state enterprises, which has been corporatized as TOT Corporation Public Company Limited (TOT) and know as TOT Public Company Limiteded and CAT Telecom Public Company Limited (CAT).

Under the BTO arrangement, the private operators, as concession holders, are required to build network infrastructure and transfer the assets to the state agencies granting the concessions. The operators thereafter have an exclusive right to use the assets during the term of the concession and operate cellular network to provide services on a revenues sharing basis with the state agencies awarding the concessions (in our case CAT) in return for the exclusive right to the use of the allocated frequency band.
