In the SEC's highest-profile trial stemming from its investigations into causes of the 2008 financial crisis, a federal jury found Tourre liable in August on six of seven civil charges he faced over the deal, which the SEC said cost investors $1 billion in losses.

In its lawsuit, the agency said Tourre - who referred to himself as "the fabulous Fab" in an email describing his activities - misled investors by failing to disclose that hedge fund billionaire John Paulson helped choose, and intended to bet against, mortgage securities underlying the deal.

"These lies mattered," lawyers for the agency told U.S. District Judge Katherine Forrest in the document.

Paulson & Co made about $1 billion from his short position on the deal, while investors including ACA Capital Holdings Inc and IKB Deutsche Industriebank AG lost about the same amount, the SEC said.

"It is critical that Tourre's conduct be addressed through significant disgorgement and penalties, to ensure that he is punished for his wrongdoing and that he and others are deterred from engaging in such conduct in the future," lawyers for the agency said in the document.

The agency asked that Tourre pay a civil monetary penalty of $910,000. It also asked that he pay $175,463 in ill-gotten gains, plus interest of $62,858.03, according to the document.

The SEC also said Tourre should be prohibited from accepting reimbursement for the penalty from Goldman.

A spokesman for Tourre declined to comment and a spokesman for Goldman Sachs did not immediately return a request for comment.

The case is SEC v. Tourre, U.S. District Court, Southern District of New York, No. 10-03229.
