(millions of yen) Sales Operating Income Ordinary Income Net Income Prior forecast (A) 43,500 1,300 1,500 10,800 Revised forecast (B) 43,500 500 700 10,200 Difference (B-A) 0 (800) (800) (600) Difference (%) 0 (61.5) (53.3) (5.6) (For reference) Prior FY results 39,302 2,624 2,540 4,107 2.Reasons for the revised forecast: Consolidated financial results forecasts for the fiscal year ending March 31, 2006, have been revised, with specific reasons for each, as follows. (1) Operating income Since last fiscal year, SCN has made great effort to increase the number of new FTTH broadband subscribers. This effort has been very successful and we plan to continue it during the second half. As a result, we anticipate that costs to acquire new subscribers will increase. In addition, due to promotional campaigns and other factors, telecommunications line usage fees and other costs will be incurred before revenues are registered. (2) Ordinary income The main reason for the downward revision in ordinary income is the same as that for operating income, as stated above. (3) Net income Lower forecasts for operating and ordinary income, as explained above, are the main reason for the downward revision in our net income forecast. (4) So-net subscriber numbers Prior forecasts of the total number of subscribers as of March 31, 2006, were 2.8 million (of which 800,000 are broadband subscribers). However, as of August 31, 2005, the total number of subscribers reached 2.78 million, of which 720,000 were broadband subscribers. As a result, we forecast that the total number of So-net subscribers as of March 31, 2006, will reach 2.95 million, of which 830,000 will be broadband subscribers.
