In what an attorney calls a story of "anger, betrayal and cover-up," we are learning that former American International Group (NYSE: AIG) CEO Maurice "Hank" Greenberg may have taken $4.3 billion in stock from the company in 2005.

This "withdrawal" reportedly occurred shortly after Greenberg was forced out of the company as he was being investigated for accounting irregularities. Attorney Theodore Wells told a jury in Manhattan yesterday that Greenberg "was mad. He was angry," deciding to give the okay to tens of millions of shares being sold from a trust fund shortly after being jettisoned from the company. The fund was put together to provide incentive bonuses to a group of AIG management and employees that they would receive when they retired.

In a landmark decision that will help millions of workers who participate in 401(k) plans at work, the Supreme Court ruled yesterday that participants could sue 401(k) administrators if they believe the administrators of their 401(k) did not follow instructions and that lack of action resulted in loss of funds. More than 50 million workers invest their retirement savings through 401(k) funds and the total amount invested is $2.7 trillion. I'm glad the Supreme Court realized workers needed protection from administrators who don't follow instructions.

The case was brought by James LaRue of Southlake, Texas. His suit contends that he lost $150,000 in his 401(k) because the administrators of his plan did not move his holdings into safer investments as he instructed. The Supreme Court had to decide whether or not the Employee Retirement Income Security Act (ERISA) allows individual account holders to sue plan administrators for breaching their fiduciary duties. The law specifically allows recovery to the "plan" rather than the individual. Justice John Paul Stevens said in his opinion for the court, "Fiduciary misconduct need not threaten the solvency of the entire plan to reduce benefits below the amount that participants would otherwise receive."
