If the tender offer for all the shares and option rights in Stonesoft Corporation is completed, the ownership of McAfee Suomi Funding LLC in Stonesoft Corporation will, based on the shares and option rights tendered into the tender offer by 11 June 2013, conditional upon the completion of settlement trades, exceed 2/3 of all the shares and voting rights in Stonesoft, based on the tender offer published on 6 May 2013 for the shares and option rights as well as the irrevocable undertakings of the three largest shareholders of Stonesoft.

According to the notification the ownership of McAfee Suomi Funding LLC, conditional upon the completion of the tender offer, (including the irrevocable undertakings given by the three largest shareholders of Stonesoft Corporation to accept the tender offer) would, after the completion of the offer be 44,003,778 (66.91%) shares and votes, assuming that all option rights offered in the tender offer would be used to subscribe shares.
