A Cayman Islands entity at the center of a U.S. investigation into possible insider trading in ketchup maker H.J. Heinz said trades placed in its Swiss bank account were made without permission.
The filing by Alpine Swift late Monday deepened a mystery about who placed an options trade that resulted in profits of more than $1.7 million in the run-up to Heinz's announcement in February that it was being bought by Warren Buffett's Berkshire Hathaway and Brazil's 3G Capital.
The Securities and Exchange Commission sued unknown parties over the suspicious trading on Feb. 15, and shortly after a federal judge froze the assets in a Swiss bank account at Goldman Sachs.
The filings came in connection with a motion by Alpine to dismiss the case. A lawyer for the investment holding company became the first person to appear for the defense in the case last week.
