U.S. Treasury Department put Alexei Mordashov and his key assets on the SDN-list: Severstal, the gold mining company Nordgold, and Severgroup, through which he controls the retailer Lenta. Being on the SDN-list means that U.S. persons are prohibited from any interaction with the company, and also implies secondary sanctions for persons outside the U.S. as well. Counterparties must complete all settlements with Severstal by August 31.
