Included in the total number of ordinary shares outstanding above are 32,830,613 (2015: 34,770,981) ordinary shares held by the Group's employee benefit trust (see (a)). The ordinary shares held by the trustee of the Group's employee benefit trust pursuant to the JSOS are treated as treasury shares in the consolidated balance sheet in accordance with IAS 32 ''Financial Instruments: Presentation''. These ordinary shares have voting rights but these have been waived by the trustee (although the trustee may vote in respect of shares that have vested and remain in the trust). The number of allotted, called up and fully paid shares, excluding treasury shares, at the end of each period differs from that used in the basic earnings per share calculation in Note 2.3 as basic earnings per share is calculated using the weighted average number of ordinary shares in issue during the period, excluding treasury shares.

(a) Treasury shares reserve

This reserve arose when the Group issued equity share capital under its JSOS, which is held in trust by the trustee of the Group's employee benefit trust. Treasury shares cease to be accounted for as such when they are sold outside the Group or the interest is transferred in full to the participant pursuant to the terms of the JSOS. Participant interests in unexercised shares held by participants are not included in the calculation of treasury shares; unvested interests of leavers which have been reacquired by the Group's employee benefit trust during the period are not accounted for as treasury shares.

(b) Fair value reserve

The fair value reserve comprises gains and losses on movements in the Group's cash flow hedges, which consist of commodity swaps and foreign currency hedges.
