Converium is being investigated by the US Securities and Exchange Commission for alleged share dealing malpractice.
The troubled Swiss reinsurer confirmed on Friday “it has received a request from the SEC for documents related to [share] transactions prior to the announcement the company made on July 20”.
The company's shares plunged 46% in July when it announced a $385m hole in the reserves at its US business.
Converium said last week that the request for the documents was made in August and that it fully intended to cooperate with the SEC in its investigations.
“The SEC is conducting an investigation into whether there has been a violation of securities law,” the company said.
