U.S. Postal Service: Another Looming Crisis

Unfortunately, at the time this was written, there seemed to be a bit of a discrepancy as to the CSRS overfunding; even though the $75 billion figure was verified by independent auditors, the Office of Personnel Management (OPM) came up with a different calculation, she notes.

Since the USPS won't be able to make its $5.5 billion payment, and given that it's not legally allowed to go under, a two-year deferral on the payment is a possible—and the most likely—scenario, according to Lyons. This will give politicians more time to work on either 
sprucing up PAEA or coming up with a new solution altogether.
