Regulators recently filed insider trading charges against 11 people, including a 26-year-old former Goldman Sachs Group investment banking analyst who’s accused of leaking confidential merger information to his brother.

The civil charges involve two separate trading rings, one involving confidential information that regulators say was leaked ahead of an announcement last year that Boston-based Liberty Mutual Insurance Co. would acquire Safeco Corp.

The Securities and Exchange Commission said Anthony Perez, of Maitland, Fla., illegally tipped his brother, Ian, with material nonpublic information that he learned from his Goldman investment banking job about the potential acquisition of Safeco in April 2008.

Ian Perez traded Safeco call options and made more than $150,000, the SEC said.

The SEC said the brothers have agreed to settle the case without admitting to or denying the allegations. Anthony Perez will pay a penalty of $25,000. Ian Perez agreed to pay disgorgement and prejudgment interest totaling $152,992.

Their lawyers could not immediately be reached for comment.

Three other individuals also were charged with trading improperly ahead of the Safeco acquisition in separate lawsuits.
