1. ARPU (Average monthly Revenue Per Unit) :

   • Average monthly revenue per unit, or ARPU, is used to measure average monthly operating revenues attributable to designated services on a per subscription basis. ARPU is calculated by dividing various revenue items included in operating revenues from our wireless services, such as basic monthly charges, voice communication charges and packet communication charges, from designated services which are incurred consistently each month, by the number of active subscriptions to the relevant services. Accordingly, the calculation of ARPU excludes revenues that are not representative of monthly average usage such as activation fees. We believe that our ARPU figures provide useful information to analyze the average usage per subscription and the impacts of changes in our billing arrangements. The revenue items included in the numerators of our ARPU figures are based on our U.S. GAAP results of operations. This definition applies to all ARPU figures hereinafter.

2. MOU (Minutes of Use) : Average monthly communication time per subscription.

1. ARPU (Xi + FOMA + mova) :
   Aggregate ARPU (Xi + FOMA + mova) = Voice ARPU (Xi + FOMA + mova) + Packet ARPU (Xi + FOMA + mova)

   • Voice ARPU (Xi + FOMA + mova) :
     Voice ARPU (FOMA + mova) Related Revenues (basic monthly charges, voice communication charges) / Number of active subscriptions (Xi + FOMA + mova)
   • Packet ARPU (Xi + FOMA + mova) :
     Packet ARPU (Xi + FOMA + mova) Related Revenues (basic monthly charges, packet communication charges) / Number of active subscriptions (Xi + FOMA + mova)

2. ARPU (FOMA) :
   Aggregate ARPU (FOMA) = Voice ARPU (FOMA) + Packet ARPU (FOMA)

   • Voice ARPU (FOMA) :
     Voice ARPU (FOMA) Related Revenues (basic monthly charges, voice communication charges) / Number of active subscriptions (FOMA)
   • Packet ARPU (FOMA) :
     Packet ARPU (FOMA) Related Revenues (basic monthly charges, packet communication charges) / Number of active subscriptions (FOMA)

3. ARPU (mova) :
   Aggregate ARPU (mova) = Voice ARPU (mova) + Packet ARPU (mova)

   • Voice ARPU (mova) :
     Voice ARPU (mova) Related Revenues (basic monthly charges, voice communication charges) / Number of active subscriptions (mova)
   • Packet ARPU (mova) :
     Packet ARPU (mova) Related Revenues (basic monthly charges, packet communication charges) / Number of active subscriptions (mova)

• Sum of Number of active subscriptions for each month ((Number of subscriptions at the end of previous month + Number of subscriptions at the end of current month) / 2) during the relevant period

• Communication module services subscriptions and the revenues thereof are not included in the ARPU and MOU calculations.
