(Reuters) – A class-action lawsuit has been filed against a group of individuals and entities. Credit Suisse (SIX:) Law firm Pomerantz LLP stated that investors were misled by the Swiss bank over transactions involving Russian oligarchs.

When Reuters reached out to Credit Suisse, they did not respond.

The lawsuit, filed in a New York district court, is on behalf of people and entities who acquired Credit Suisse securities between March 19, 2021 and March 25, 2022, Pomerantz said in a statement issued late on Friday.

Pomerantz claimed in the statement, “The complaint alleges the defendants made materially inaccurate and misleading statements concerning the company’s business, operations and compliance policies throughout the class period.”

A securitization deal was criticized by the law firm for alleged discrepancies. In its statement, it referred to a February Financial Times article in which Credit Suisse reported that they had secured a portfolio of loans tied to wealthy customers’ yachts. Credit Suisse also used derivatives in unusual ways to offset the risk of lending to entrepreneurs and ultra-rich oligarchs.

The Financial Times said that after the publication of its article, Credit Suisse said in a statement that the transaction “priced in line with other significant risk transactions, offered competitive investment and hedging terms for our professional investor clients while increasing the capital flexibility of the bank.”

In addition, the lawsuit referred to an April request by Credit Suisse by U.S lawmakers for documents regarding yacht financing and private jets that were owned by sanctioned persons.

Credit Suisse claimed that none of its client data has been deleted when it requested investors destroy records relating to transactions in November. It was responding to another Financial Times report about oligarchs.

Credit Suisse has stopped pursuing Russian business after the Ukrainian invasion on February 24, as the Swiss bank stated in an internal document to Reuters on March 28, 2018.

Credit Suisse has reported a quarter-quarter loss. This week it suffered from a string of expensive hits as well as a series legal cases, some of which it called legacy matters.
