HELSINKI (Reuters) - Finnish utility Fortum (>> Fortum Oyj) has been offered just 0.17 percent of shares in Germany's Uniper (>> Uniper SE) by Tuesday on top of a 46.65 percent stake that it bought from E.ON (>> E.ON), a regulatory filing showed.

Fortum in September clinched a deal to buy E.ON's stake, but then launched a full takeover bid worth 8.05 billion euros (7.10 billion pounds) to all Uniper shareholders due to German takeover rules.

Uniper owners can tender shares by Jan. 16 and an additional acceptance period is expected to take place between Jan. 20 and Feb. 2.
