Fred Drasner, vice chairman of U.S. News & World Report, is assuming the additional posts of president and chief executive officer, the magazine's chairman Mortimer B. Zuckerman announced late Friday.

The new positions will give Drasner, 42, complete responsibility for the all of the company's operations, including the magazine, its electronic publishing subsidiary and its photo-composition division. Since Zuckerman purchased the magazine last fall, Drasner has overseen the company's operations as vice chairman. "This is a formalization of the duties he has had all along," said company spokeswoman Kathryn Bushkin.

With Drasner's appointment, Zuckerman has filled all of the top spots at the company. Shelby Coffey III, formerly The Washington Post's assistant managing editor for national news, assumed the editor's post earlier this month.

Richard C. Thompson, director of advertising sales for Business Week, has just become publisher, with James C. Mason, also from Business Week, becoming associate publisher.

James K. Glassman will continue to serve as U.S. News' executive vice president, overseeing the day-to-day business operations, Bushkin said. "Drasner will have overall responsibility for all the businesses," she said.

Drasner, who has been an attorney with Shaw Pittman Potts & Trowbridge since 1972, will continue to be a partner in the law firm, Bushkin said.

"Fred Drasner is a brilliant business lawyer with a creative sense for business management, operation and development," Zuckerman said in announcing the appointment.
