Alleged Madoff fraud has worldwide exposure

The 70-year-old Madoff, well respected in the investment community after serving as chairman of the Nasdaq Stock Market, was arrested Thursday in what prosecutors say was a $50 billion scheme to defraud investors. Some investors claim they've been wiped out, while others are still likely to come forward.

The alleged victims who sunk cash into veteran Wall Street money manager Bernard Madoff's investment pool include real estate magnate Mortimer Zuckerman, the foundation of Nobel laureate Elie Wiesel, and a charity of movie director Steven Spielberg, according to The Wall Street Journal.

On Friday, representatives from major U.S. banks -- Bank of America Corp., Citigroup Inc., PNC Financial Services Group Inc. and Merrill Lynch & Co. -- declined to comment on whether they had exposure to Madoff's company. Both BlackRock Inc. and Goldman Sachs Group Inc. said they had no exposure.

Among those overseas confirming exposure on Monday, Banco Santander, the largest bank in the euro zone by market capitalization, said its clients have 2.33 billion euros ($3.07 billion) in exposure with Madoff, mostly through a fund called Optimal Strategic US Equity.

The Wall Street Journal, citing a person familiar with the matter, said Mortimer Zuckerman, the chairman of real estate firm Boston Properties and owner of the New York Daily News and U.S. News & World Report, had significant exposure through a fund that invested substantially all of its assets with Madoff.

Reports from Florida to Minnesota included profiles of ordinary investors who gave Madoff their money. Some had been friends with him for decades, others were able to invest because they were a friend of a friend. They told stories of losing everything from $40,000 to an entire nest egg worth well over $1 million.

Morgan Stanley, Wells Fargo & Co., Comerica Inc. and U.S. Bancorp did not return calls seeking comment.
