Derivatives: Anticipated adjustment due to Boliden’s redemption process (15/07)

The following information is based on a press release from Boliden AB (Boliden) dated February 8, 2007 and may be subject to change.

The board of Boliden has proposed that the Annual General Meeting (AGM) approves a redemption process whereby every Boliden share entitles the holder to one (1) redemption share, which will be subject to compulsory redemption for a cash payment of SEK 12,00. If the AGM, which will be held on May 3, 2007, approves the proposal, OMX Derivatives Markets will carry out a re-calculation of options and futures in Boliden and adjust the OMXS30 index.
