     Voice ARPU (FOMA + mova) Related Revenues (monthly charges, voice transmission charges) / Number of active cellular phone subscribers (FOMA + mova)
   • Packet ARPU (FOMA + mova) :
     {Packet ARPU (FOMA) Related Revenues (monthly charges, packet transmission charges) + i-mode ARPU (mova) Related Revenues (monthly charges, packet transmission charges) } / Number of active cellular phone subscribers (FOMA + mova)
   • i-mode ARPU (FOMA + mova)1 :
     i-mode ARPU (FOMA + mova) Related Revenues (monthly charges, packet transmission charges) / Number of active cellular phone subscribers (FOMA + mova)
   • ARPU generated purely from i-mode (FOMA + mova)2:
     i-mode ARPU (FOMA + mova) Related Revenues (monthly charges, packet transmission charges) / Number of active i-mode subscribers (FOMA + mova)

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