• Compared to 2Q 2003, total operating revenue decreased KRW 153.9 billion (5.2%).

• In the third quarter of 2003, telephone revenue totaled KRW 1,152.3 billion, down KRW 60.8 billion (5.0%). It is due to i) a decrease in subscription fee as growth rate of new subscriber and switching subscriber to non-refundable deposit program diminished, and ii) a decrease in international long distance usage. Local and domestic long distance revenues declined due to accounting re-categorization of VAS (Value Added Service). 114 phone directory revenue declined significantly because one-time KRW 33.5 billion was recognized in 3Q 2002 as settlement for 114 phone directory service provided to mobile.

• Compared to the previous quarter, telephone revenue decreased by KRW 29.5 billion (2.5%) because of decrease in subscriber connection and international long distance revenues.
