Everton insist there is no current impact on the stadium project and no plans to change sponsorship or USM logos at Finch Farm amid concerns over the situation in Russia.
Earlier this week, Russian president Vladimir Putin launched a military invasion of Ukraine.
The move has prompted huge backlash from the international community with the USA announcing "unprecedented and expansive" sanctions against Russia.
In a US Treasury document, it has now been confirmed this includes blocking of "property and interests in property" of various Sovcombank subsidiaries.
Named on that list is 'USM Limited Liability Company', which is described as a "financial company located in Russia".
Everton sources said there is a difference between the USM facing sanctions and 'USM Holdings', which has sponsorship ties with the club.

The ECHO asked whether 'USM LCC' was affiliated to Alisher Usmanov.
Indications from the club were that Usmanov 'categorically' has no links to that company.
And it is 'USM Holdings' which sponsors Everton's training ground at Finch Farm.
A page on the Everton website reads: "Everton Football Club confirmed a naming rights partnership with USM Holdings in January 2017, with the Russian-based group becoming the Club’s first ever training ground partner".
Blues owner Farhad Moshiri has a small shareholding in 'USM Holdings', a firm where his friend and business associate Usmanov is majority shareholder.
'USM Holdings' is not believed to be under threat of sanctions.
As a result, there is not expected to be any change at the Everton end in terms of stadium progress or visibility of sponsorship.
According to a Telegraph report, Uzbek-born Usmanov and fellow billionaire Roman Abramovich are not set to be hit with British sanctions.
There had been calls in Parliament for Russian national Abramovich to lose his ownership of Chelsea, with Usmanov's name also being cited by Labour MP Margaret Hodge who suggested current action against Russia was too "narrow".
Back in 2010 in an interview with Forbes magazine, Usmanov said: "I am proud that I know Putin, and the fact that everybody does not like him is not Putin's problem".
It was confirmed this morning that the Champions League final, due to be held at St Petersburg’s Gazprom Arena in May, will take place in Paris.
A Uefa statement said: "Uefa wishes to express its thanks and appreciation to French Republic President Emmanuel Macron for his personal support and commitment to have European club football’s most prestigious game moved to France at a time of unparalleled crisis."
