DoCoMo have just posted their financial results for the quarter ending 31 December 2005. Operating revenues came in at 3,582.2 bn yen, down 1.7% year-on-year — not bad considering the downward trending ARPU. Operating income was 693.5 bn yen, down 7.7% and income before taxes was 811.2 bn yen, down 32.1%. The lower profits indicate that costs to operate and expand the 3G service continue to remain high. But there are few companies — much less 3G carriers — faced with the ‘problem’ of calculating taxes on 8 billion bucks of profit.
