NT filed a complaint with the Arbitral Tribunal on Sept 27, 2018, claiming additional revenue share from roaming services from AIS. The additional revenue share amounted to some 16.25 billion baht with a penalty interest rate of 1.25% per month. The complaint was based on the seventh amendment to the main concession agreement from July 2013 to September 2015.
Advanced Info Service Public Company (AIS), the Thai associate of Singapore Telecommunications (SGX:Z74) (Singtel), is “not obligated” to pay the additional revenue share claimed by National Telecom Public Company (NT).
According to AIS’s statement released on July 14, the dispute was concluded after the Thai Supreme Administrative Court dismissed NT’s appeal on July 12.
