Microsoft Tried to Buy SAP

Microsoft disclosed that it began merger discussions with German software company SAP late last year but that the talks ended because Microsoft decided the deal would be too complex. The company said it was disclosing the discussions because it expects Oracle to bring them up in an antitrust trial over Oracle's proposed acquisition of rival PeopleSoft. SAP confirmed that the discussions had ended but did not say why. Microsoft's talks with SAP could be important to the antitrust case because one sticking point in the trial is whether Microsoft is plotting a further expansion into business applications software.

Pension cutbacks for some early retirees were ruled illegal by the Supreme Court. Two Illinois construction workers were told when they retired in 1996 that they could draw retirement benefits as long as they did not take certain jobs in the same industry. Both took jobs as construction supervisors, and in 1998 the Central Laborers' Pension Fund told them that they could not draw a pension while working in any construction industry job. The court said an employer cannot change benefits after a worker has retired.

A consumer watchdog group sued three cell phone companies for "locking" their phones to make it harder for customers to switch carriers. The Foundation for Taxpayer and Consumer Rights filed suit accusing AT&T Wireless, T-Mobile and Cingular Wireless of using software in their handsets that prevents them from being used on competitors' networks. The practice effectively thwarts recent federal regulations allowing people to retain their phone numbers when switching mobile carriers, according to the lawsuit, filed in Superior Court in Los Angeles. The phone companies defend their policy, saying they routinely subsidize handset cost and would lose money if they allowed customers to use those phones with another carrier.

The notion of energy independence is a myth and the United States must maintain "constructive relationships" with oil-producing countries for its own prosperity, the head of Exxon Mobil said. "We do not have the resource base to be energy independent," Lee R. Raymond said in a speech in Washington in which he outlined some of what he called the "hard truths" about global energy markets. He added, "We periodically hear calls for U.S. energy independence as if this were a real option."

The 2004 Mazda RX-8 four-door sports car was the only vehicle to get a top rating during rollover tests by the National Highway Traffic Safety Administration.

Seven SUVs or pickups tipped up on two wheels during the tests, though none got less than three stars (21 to 35 percent chance of serious injury).

Tyco International's former top lawyer got a bonus for guiding the company unscathed through a federal investigation before the inquiry had been completed, a former board member said. Testifying at Mark A. Belnick's larceny and fraud trial, Frank E. Walsh Jr. said the bonus was approved in May 2000, three months before the Securities and Exchange Commission ended its inquiry. Prosecutors contend that the timing of the bonus, possibly as much as $17 million, indicates it was actually a payoff for helping to hide former chief executive L. Dennis Kozlowski's alleged thefts.
