Postal Service Suffers Record $15.9B Loss Organization could be out of cash in a year By Matt Cantor, Newser User Posted Nov 16, 2012 1:43 AM CST 35 comments Comments In this Dec. 5, 2011 file photo, mail is loaded into bins for transport at the Capitol Station in Springfield, Ill. (AP Photo/Seth Perlman, File) (Newser) – The struggling US Postal Service has posted a record loss of $15.9 billion for the fiscal year ending Sept. 30. The agency defaulted this year on $11.1 billion in health benefits for retirees, and it's suffering as first-class mail, its top source of revenue, falls off, the Wall Street Journal reports. The USPS could run out of cash in a year if lawmakers don't do something, officials say. (But it thinks it will have enough cash to make it til next fall thanks to record volumes of election-theme material and an expected 20% revenue bump due to holiday shipping.) "If Congress fails to act, there could be postal slowdowns or shutdowns that would have catastrophic consequences"—not just for the Postal Service itself, but for businesses that depend on it, says the head of an advocacy group.
