FTSE Russell, however, said in its quarterly report https://www.ftserussell.com/press/ftse-uk-index-series-quarterly-review-march-2020 late on Wednesday that if NMC has not resumed trading by the close of business on March 18, it will be retained within the FTSE 100 index until its resumption.

Shares of Abu-Dhabi based NMC had lost about two-thirds of their value since U.S.-based short-seller Muddy Waters late last year questioned the company's financial statements.

Britain's Financial Conduct Authority also opened an investigation into the company following the trading suspension on Feb. 27.

FTSE Russell also removed Kingfisher and TUI AG from the FTSE 100 index and added Fresnillo, Intermediate Capital Group and Pennon Group.
