Definition and Calculation Methods of ARPU and MOU

Definition of ARPU and MOU

  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 user basis. ARPU is calculated by dividing telecommunications services revenues (excluding certain revenues) by the number of active users of our wireless services in the relevant periods, as shown below "ARPU Calculation Method." We believe that our ARPU figures provide useful information to analyze the average usage per user and the impacts of changes in our billing arrangements.
  2. MOU (Minutes of Use) : Average monthly communication time per user.

ARPU Calculation Methods

Aggregate ARPU= Mobile ARPU + "docomo Hikari" ARPU
  • Mobile ARPU :Mobile ARPU Related Revenues {Voice related revenues (basic monthly charges, voice communication) + Packet related revenues (basic monthly charges, packet communication charges)}
    / Number of active users
  • "docomo Hikari" ARPU :"docomo Hikari" ARPU Related Revenues (basic monthly charges, voice communication changes) /Number of active users
