Uniper late on Sunday disclosed the payment it was ordered to make by the International Chamber of Commerce to an unnamed European energy company, only saying the affected long-term contract was concluded before its spin-off from E.ON in 2016 and had expired in 2022.

The 2017 annual report by the International Group of LNG Importers (GIIGNL) showed a 15-year contract under which Eni supplied Uniper with 0.65 million tonnes of LNG per annum between 2007 and 2022.

Uniper declined to comment. Eni was not immediately available for comment.
