USPS OIG Report March 29, 2021
On March 29, 2021 the USPS Office of the Inspector General reported on a self-initiated audit of USPS finances to determine the effects of the pandemic on Postal finances.
From March of 2020 through FYE in September 2020, the US Postal service separated out pandemic related expenses from daily operating expenses, with the goal of determining their financial impact. Pandemic related expenses included supplies and services, which were tracked directly, as well as transportation expenses which were estimated, and sick and annual leave expenses.
At the onset of the pandemic in the US, a drop in letter mail volume created an expectation that the USPS financial condition would worsen. However, as the pandemic wore, on revenue increased due to increases in package volume. Though expenses also increased, near term liquidity improved. Revenue at FYE 2020 was $73.1 billion – between $2.9 billion and $6 billion greater than projected.
