• Average Revenue per User (“ARPU”) : Average monthly recurrent revenue per customer (excluding visitors roaming revenue and connection fee). This includes airtime revenue (national and international), as well as, monthly subscription fee, SMS, GPRS & data revenue. Quarterly ARPU is calculated as an average of the last three months.

  • Capital Expenditure (“Capex”) : Tangible & Intangible fixed assets additions during the reporting period, includes work in progress, network, IT, and other tangible and intangible fixed assets additions but excludes license fees.

  • Churn : Disconnection rate. This is calculated as the number of disconnections during a month divided by the average customer base for that month.

  • Churn Rule : A subscriber is considered churned (removed from the subscriber base) if he exceeds the 90 days from the end of the validity period without recharging. It is worth noting that the validity period is a function of the scratch denomination. In cases where scratch cards have open validity, the subscriber is considered churned in case he has not made a single billable event in the last 90 days (i.e. outgoing or incoming call or sms, wap session). Open cards validity is applied for GTA, Mobilink and banglalink so far.
