Free-Float Weight (FFW) is a weight of listed shares deemed to be available for trading in the market. FFW is determined and calculated by TSE for each listed company for use in index calculation.
FFW figures range from 0.00 to 1.00 and the split-point is 0.01. FFW of company A may be different from that of company B.
FFW is reviewed once a year in order to reflect the latest distribution of share ownership. The timing of the FFW review will differ according to the settlement terms of listed companies. In addition to the periodic review, extraordinary reviews will be conducted in cases where the FFW has changed significantly due to the allocation of new shares to a third party and the like. Details of FFW are described in the "Tokyo Stock Exchange Index Guide Book".
