Tokyo Stock Exchange Free-Float Weight (FFW) Use For TOPIX And Its Sub-Indices

Date 01/02/2006

Tokyo Stock Exchange, Inc. (TSE) published today the Free-Float Weight (FFW) to be used for TOPIX and its sub-indices after the close of trading on February 27, 2006.
As TSE announced on July 23, 2004, it will introduce FFW for these indices in three phases. The first and second phases will start after the close of trading on October 28, 2005 and February 27, 2006 respectively, and the final phase will be implemented after the close of trading on June 29, 2006.
In the case of a company with a FFW of 0.70, for example, 0.90 will be used for calculating indices in the first phase, 0.80 in the second phase and 0.70 in the final phase.
As published in the press release dated April 1, 2005, the FFW of a newly added company to TOPIX after the close of trading on October 28, 2005 (excluding listing companies newly-created through a stock-swap or merger), will not be introduced through the three-phase approach, but all at once when the stocks are added to the indices.
Please refer to the list of FFW in TOPIX as of February 1, 2006, which is to be used in the second phase.
