LONDON (Reuters) - The London Stock Exchange lifted the suspension on En+ Group’s London-listed global depositary receipts (GDRs) available to U.S. investors, a spokeswoman said on Monday after Washington dropped sanctions on the Russian company.

The halt was lifted at 0900 GMT, she said. Data shows the GDRs, which are worth $9.7 each, have not yet traded.

U.S. President Donald Trump’s administration on Sunday lifted sanctions on the core empire of Russian tycoon Oleg Deripaska, including aluminum giant Rusal and its parent En+, despite a Democrat-led push to maintain them.

Trading in En+’s other London-listed GDRs did not stop under the sanctions, which were imposed in April last year, but they have not traded since Aug. 14. They are worth $5.4 each, down from $9.5 before the sanctions.

GDRs are certificates that allow UK and international investors to hold shares in En+.
