The KDDI Group was established in October 2000 through the merger of DDI CORPORATION, KDD Corporation, and IDO CORPORATION. Thereafter, we expanded our business foundation through M&As in both the mobile business and fixed-line business. We are proud to be the only company in Japan to have a uniquely comprehensive business structure combining mobile and fixed-line communications in a single company, and establishment of a solid foundation for growth.
Operating revenues in the nine months ended December 31, 2009 amounted to ¥2,001,379 million, down 2.3%
year on year. Contributing factors included the decrease in ARPU (average revenue per user) caused by the
increased uptake of low-rate plans and decreased revenue from handset sales caused by smaller handset unit sold.
Operating expenses declined due to decreases in sales commissions and handsets procurement cost due to the
decrease in handset sales unit.
