Adelphia Communications, the nation's fifth-largest cable television provider, said it has held preliminary talks with potential bidders and hopes to complete the discussions by the end of the year. Executives then will decide whether it will be best to sell all or part of the assets or emerge from bankruptcy as a stand-alone company, a spokesman said. Adelphia filed for bankruptcy protection two years ago after founder John J. Rigas and others were accused of looting the company and cheating investors out of billions of dollars. John Rigas and his son Timothy later were convicted of conspiracy, bank fraud and securities fraud.

Consumers stepped up their borrowing in June, though at a slower pace than seen during the previous month, the Federal Reserve reported. Consumer credit increased at a seasonally adjusted annual rate of 3.9 percent in June, or by $6.6 billion, from the previous month. That compared with a brisk 4.8 percent pace in May, an $8 billion rise. Total consumer credit outstanding is now a record $2.04 trillion. The Fed's report includes credit card debt and loans for such things as boats, cars and mobile homes, but not mortgages or home-equity loans.

Four former Halliburton employees, in a new filing in a class-action lawsuit, contend the oilfield-services giant engaged in systematic accounting fraud from 1998, when Dick Cheney ran the company, to 2001. Cheney, who left Halliburton in August 2000 to run for vice president, was not named as a defendant in the filing. The former finance employees say that Halliburton divisions routinely inflated their results by overstating amounts due from customers and understating money owed to vendors and that top executives hid Halliburton's vulnerability to asbestos claims. The charges in the filing go far beyond those outlined this week in a settlement of a civil lawsuit by the Securities and Exchange Commission, which called for Halliburton to pay $7.5 million for failing to disclose a change in accounting procedures in 1998.

University of Missouri officials said that if Enron founder Kenneth L. Lay is convicted of defrauding investors, they would prefer to remove his name from an economics professorship he endowed, which would probably require the return of his $1.1 million donation. Lay, a Missouri alumnus, was indicted last month on 11 criminal counts, including conspiracy, securities fraud and bank fraud, for his alleged role in the corporate scandal that brought down Enron. He has pleaded not guilty.

American Airlines will pay a $3 million civil penalty to resolve Justice Department concerns that it violated terms of a 1994 consent decree intended to promote airfare competition. The penalty was part of a settlement filed in U.S. District Court in Washington, the Justice Department announced. The department said American violated terms of the 1994 decree by publishing certain fares with increased advance purchase requirements only for future travel dates, rather than current travel. This effectively reduced American's risk of losing passengers to other airlines.

Roy E. Disney, a former director of Walt Disney Co., can't disclose company executives' compensation information to boost his campaign to oust chief executive Michael D. Eisner, a judge ruled. Delaware Chancery Court Judge Stephen P. Lamb ruled that the company didn't have to drop confidentiality restrictions on documents outlining how directors set Eisner's and other executives' pay over a two-year period starting in 2002. Roy Disney left the company board last year to lead a campaign to force Eisner to step down over claims that he'd mismanaged the world's No. 2 media company. Eisner resigned as chairman in March after he failed to win the support of 45 percent of the shares voted at the company's annual meeting, but retained his board seat and chief executive post.
