Danish building materials company Rockwool said on ​Tuesday that Russia has taken ‌control of the company's four factories in ‌Russia and the company is no longer in control of its assets in the country.

Rockwool's statement ⁠said the ‌factories will be de-consolidated and the net value of ‍its businesses there will be written down, adding that their total equity amounted ​to 469 million euros ($546 million) ‌at December 31.

The company added that it will defend its legal rights under the bilateral investment treaty between the countries, but added: "We ⁠are not optimistic ​about reversing the ​decision to place our Russian subsidiaries under forced external administration."

Rockwool ‍shares fell ⁠8% earlier on Tuesday after the seizure of two subsidiaries ⁠was reported by Bloomberg.
