The Postal Service repeated on Wednesday that without congressional action, it will default—a first in its long history, a spokesman said—on a legally required annual $5.5 billion payment, due Aug. 1, into a health-benefits fund for future retirees. Action in Congress isn't likely, as the House prepares to leave for its August recess.

 

The agency said a default on the payment, for 2011, wouldn't directly affect service or its ability to pay employees and suppliers. But "these ongoing liquidity issues unnecessarily undermine confidence in the viability of the Postal Service among our customers," said spokesman David Partenheimer.
