Index Change Advice 20121212 Shareholder Weighted (SWIX) Index Methodology FTSE/JSE Africa Index Series 12 December 2012 FTSE/JSE has undertaken significant market research on the SWIX Index methodology over the past year through consultative papers, workshops and direct client visits. The FTSE/JSE Advisory Committee (AC) met today to discuss and approve the SWIX methodology which will be effective from 18 March 2013, and to confirm that the SWIX free float will move from a banded methodology to an actual methodology from March 2013. New SWIX Index Methodology: Under the new methodology all constituents will be down-weighted in the SWIX indices by applying an alternate free float, called the SWIX free float. The SWIX free float represents the proportion of a constituent’s share capital that is held in dematerialised form on the South African share register. This information is obtained from Strate (Strate is the authorised Central Securities Depository for the electronic settlement of financial instruments in South Africa). An average of the total holdings on the South African share register, in the 3 months prior to the review month, with a one month lag, is used to calculate the SWIX free float. In the event that this figure is not available, the FTSE/JSE company free float is used. Where the company’s free float is lower than its SWIX free float, the company free float will be used. In addition all securities deemed not available for local trade, but included on the Strate register will be subtracted from the free float number calculated as per above. This will initially include holdings confirmed to back a listed, sponsored Depositary Receipt (DR) program.
