The roster of potential victims in what prosecutors said was a $50 billion Ponzi scheme has grown exponentially longer in the past few days.

Madoff, 70, said in regulatory filings that he only had around 25 clients, but it has become apparent that the list of people who lost money may number in the hundreds or even thousands.

Among those who have acknowledged potential losses so far: Former Philadelphia Eagles owner Norman Braman, New York Mets owner Fred Wilpon and J. Ezra Merkin, the chairman of GMAC Financial Services.

A charity in Massachusetts that supports Jewish programs, the Robert I. Lappin Charitable Foundation, said it had invested its entire $8 million endowment with Madoff. The organization's executive director said she doesn't expect it to survive.

Other institutions that believed they had lost millions included The North Shore-Long Island Jewish Health System and the Texas-based Julian J. Levitt Foundation.

Hedge funds and other investment groups looked like big losers too. The Fairfield Greenwich Group said it had some $7.5 billion in investments linked to Madoff. A private Swiss bank, Banque Benedict Hentsch Fairfield Partners SA, said it had $47.5 million worth of client assets at risk.

The settlement would also block any new lawsuits against Travelers arising out of the insurance company's long relationship with Johns Manville Corp., once the world's largest producer of asbestos.

Travelers has been named in dozens of lawsuits claiming that it tried to hide the dangerous health effects of asbestos. Asbestos is a mineral that was commonly used until the mid-1970s in insulation and fireproofing material. Exposure can increase the risk of lung cancer, mesothelioma and other ailments, according to federal health agencies.

The company has argued that asbestos-related claims should be paid out of a trust created by Johns Manville in the 1980s and approved by a federal bankruptcy judge. Money for the fund came largely from insurers.

Travelers agreed to settle with several groups of plaintiffs provided that federal courts make clear that it would not have to face any new similar lawsuits.

The 2nd U.S Circuit Court of Appeals in New York overturned lower-court approval of the settlement, saying a bankruptcy judge lacks the authority to act so broadly. The justices, at arguments in March, will consider the question of the bankruptcy court's power.

The consolidated cases are The Travelers Indemnity Co. v. Bailey, 08-295, and Common Law Settlement Counsel v. Bailey, 08-307.

The justices threw out a decision by the San Francisco-based 9th U.S. Circuit Court of Appeals in the case of Michael Robert Pulido, who was convicted for his role in robbing a gas station and killing the defendant.

A U.S. District Court judge set aside Pulido's conviction because the trial judge in the case gave the jury improper instructions.

The high court said in an unsigned opinion that the appeals court ruling affirming the federal judge's action used faulty reasoning. The justices did not reinstate Pulido's conviction.

Justices John Paul Stevens, Ruth Bader Ginsburg and David Souter agreed that the appeals court made a mistake, but would have affirmed its ruling anyway because the underlying decision in favor of Pulido was correct.

Last month, the court overruled the 9th Circuit in an environmental case involving the Navy's use of sonar and its potential harm to whales.

The case is Hedgpeth v. Pulido, 07-544.

The family also filed notice that Nassau County, on Long Island, and its police department will be sued.

The lawsuit against Wal-Mart and the Long Island mall where it is located was filed Wednesday in state Supreme Court in the Bronx on behalf of Elsie Damour Phillipe. Phillipe is the sister of victim Jdimytai Damour (DHMEE'-tree Di-MOHR'), and is the court-appointed administrator of his estate.

Damour, a temporary worker hired for the holiday season, was crushed to death when some 2,000 customers stormed into the Valley Stream store.

None of the defendants in the lawsuit immediately responded to requests for comment.
