NEW YORK — The Washington Post Co. revealed exactly how much cash audio equipment magnate Sidney Harman paid for Newsweek magazine this summer: $1.

The Post Co. also agreed to cover up to $10 million of Newsweek's existing bills. And it will hold on to certain employee pension liabilities, though it did not spell out a dollar figure in a regulatory filing Wednesday.

No one thought Harman paid much for Newsweek, but the magazine's sale for less than its $5.95-per-issue price on newsstands is still a grim milestone.
