Number of active subscribers used in ARPU / MOU / Churn Rate calculations are as follows:

• 4Q Results :
  Sum of Number of subscribers for each month from January to March
• FY Results :
  Sum of Number of subscribers for each month from April to March

Calculation methods for Number of active subscribers used in ARPU (mova, PHS, i-mode (mova), generated purely from i-mode (mova)), MOU (mova, PHS) and Churn rate changed as of 4th quarter and full year results.

Numerical values by previous calculation methods are as follows:

• 4Q Results :
  {(Number of subscribers at Dec. 31 + Number of subscribers at Mar. 31) / 2} x 3 months
• FY Results :
  {(Number of subscribers at the end of previous fiscal year + Number of subscribers at the end of current fiscal year) / 2} x 12 months
