Postal Service’s $15.9-Billion Loss Highlights Urgent Need for Legislative Reform: The U.S. Postal Service ended the 2012 fiscal year (Oct. 1, 2011 – Sept. 30, 2012) with a record net loss of $15.9 billion, compared to a net loss of $5.1 billion for the same period last year. The loss included expenses of $11.1 billion related to two payments to prefund retiree health benefits. Resolving the prefunding requirement, which made up 70 percent of the net loss, and providing more commercial flexibility to allow the Postal Service to manage its business, are among legislative changes needed for USPS to fully implement its business plan to return to financial stability.
