Final results of Fortum's MTO to TGC-10 minorities available end of October In April 2008, Fortum made a mandatory public tender offer (MTO) for the entire share capital of Territorial Generating Company No. 10 (TGC-10) to TGC-10 minorities. At the end of September, Fortum's ownership in TGC-10 was over 93% including shares owned by TGC-10's fully-owned subsidiary. By that time Fortum had paid EUR 440 million for share purchases under the MTO. Clearing of the share transactions is still ongoing and the final results of the MTO will be known and published at the latest at the end of October 2008 when Fortum will have to submit the final report on the results to the Russian regulators. In the event that Fortum's shareholding in TGC-10 exceeds 95% as a result of the MTO Fortum may redeem the remaining shares in TGC-10. The redemption of remaining shares is, however, subject to decision by Russian authorities.
