Index Rules*

Only the eligible quoted equity capital of a constituent company will be included in the calculation of its market capitalisation. Where a company has two or more classes of equity, significant and liquid secondary lines will be included in the calculation of the market capitalisation of the company, based on the market price of that secondary line. Unless the FTSE Regional Committee deems it inappropriate, a secondary line will be priced separately if its full market capitalisation, i.e. before the application of any investibility weightings, is greater than 25% of the full market capitalisation, of the company’s main line and the secondary line is eligible, in its own right. Secondary lines that are less than 25% of the company’s main line will be excluded. Should the full market capitalisation of a secondary line, which is already a constituent of the Index, fall below 20% of the company’s main line at the quarterly review, the secondary line will be deleted from the index.

Where a company's shares are issued partly, or nil, paid and the call dates are already determined and known, the market price will, for the purposes of calculating its market capitalisation, be adjusted so as to include all such calls (i.e. the fully paid price).

Convertible preference shares and loan stocks will be excluded until converted.

Companies whose business is that of holding equity and other investments (e.g. Investment Trusts) will be eligible for inclusion. However, those investment funds - including Split Capital Investment Trusts that have been assessed as being in sector 89, are excluded.

The FTSE Regional Committees must be satisfied that an accurate and reliable price for the purposes of determining the market value of a company exists.
