Net sales increased by 7,870 million yen (2.3%) year on year to 356,562 million yen, and operating income increased by 14,941 million yen (64.8%) to 38,006 million yen.
Inter-segment sales increased due to network provision to Group telecommunication companies such as SOFTBANK MOBILE, and contributed to the segment's overall revenue growth. On the other hand, net sales to third-parties decreased, primarily as a result of the continued decrease in revenue from relay connection voice services such as MYLINE, and despite an increase in revenue from the OTOKU Line direct connection voice service.
The increase in operating income was mainly due to the increase in net sales, combined with a decrease in lease expenses on equipment for the OTOKU Line service.
SOFTBANK TELECOM, the core company of the Fixed-line Telecommunications segment, is working to expand its corporate business base, primarily through OTOKU Line. The number of OTOKU Line installed lines and ARPU both grew steadily in fiscal 2011. The number of OTOKU Line installed lines reached 1,671,000 lines as of the end of fiscal 2011 with corporate contracts accounting for 84% of the total. OTOKU Line ARPU for the fiscal 2011 fourth quarter was 6,930 yen, a 110 yen increase from the same period of the previous fiscal year.
