• p is the latest trade price of the component security (or the price at the close of the<br />

<strong>Index</strong> on the previous day).<br />

• s is the number of shares in issue used by <strong>FTSE</strong> for the security, as defined in these<br />

<strong>Ground</strong> <strong>Rules</strong>.<br />

• f is the Investability Weighting Factor to be applied to a security to allow amendments to<br />

its weighting, expressed as a number between 0 and 1, where 1 represents a 100% free<br />

float. This factor is published by <strong>FTSE</strong>/<strong>JSE</strong> for each security in the underlying index.<br />

• d is the divisor, a figure that represents the total issued share Capital of the <strong>Index</strong> at the<br />

base date. The divisor can be adjusted to allow changes in the issued share Capital of<br />

individual securities to be made without distorting the <strong>Index</strong>.<br />
