This article is from a public accessible publication of the USPS that I was reading today. Please note the section whereas:
“the legislation added a new requirement that the Postal Service fund $27 billion to cover military service time for its employees.” “Congress passed Civil Service Retirement System (CSRS) legislation last year, and while it saved the Postal Service from overfunding the retirement system by billions, the law’s funding plan is unfair to postal customers, according to a report by the Postal Service Office of Inspector General (OIG).

The Postal Service was scheduled to overpay the CSRS fund by $105 billion, primarily due to higher than expected interest earnings, when Congress passed CSRS legislation. However, the legislation added a new requirement that the Postal Service fund $27 billion to cover military service time for its employees.”
