I. Introduction

On May 28, 2026, the Postal Service filed a petition pursuant to 39 CFR 3050.11 requesting that the Commission initiate a rulemaking proceeding to consider a proposed change to analytical principles relating to the Postal Service's periodic reports.\1\ The Petition identifies the proposed analytical principles change filed in this docket as updates and refinements to the reporting of window service costs. Petition, Proposal at 3. Specifically, the Postal Service seeks to overhaul the existing methodology to correct identified mathematical and econometric errors and to reflect changes in window service volumes and operations. Id. --------------------------------------------------------------------------- \1\ Petition of the United States Postal Service to Initiate a Proceeding to Change Analytical Principles, and Notice of Filing USPS-RM2026-6-NP1, May 28, 2026 (Petition). The proposed change is attached to the Petition (Proposal). The Petition was accompanied by a study supporting its Proposal. See Michael D. Bradley, Updating and Refining Window Service Costs, May 28, 2026. ---------------------------------------------------------------------------

II. Proposal

Background. The Postal Service states that the existing methodology for reporting window service costs was established in Docket No. R90-1 and refined in Docket Nos. R97-1 and R2006-1. Id. The Postal Service notes that there have been significant changes in window service volume and operations since the established methodology was last updated. Id. The Postal Service also identifies errors in the established methodology that, when corrected, contradict existing ``assumptions that both network time and waiting time were one hundred percent variable with visit time during the late 1980s.'' Id. The Postal Service additionally identifies data limitations underpinning the established methodology that can be ameliorated by using modern data captured using its Retail Systems Software (RSS) point-of-sale system. Id. at 4. Proposal. The Postal Service proposes correcting, updating, and/or refining four of the five variabilities that go into calculating volume variable window service costs. Id. at 5. Visit time variability is proposed to be updated using RSS data, the application of Stochastic Frontier Analysis (SFA) to account for non-item time, and a revised method for directly estimating the response in visits to changes in window service volumes. Id. at 5-9. Network variability is proposed to be updated by correcting a mistaken formula in the established methodology and making improvements to comport with current Commission standards. Id. at 9-10. Waiting time variability is proposed to be updated to adjust assumptions in the established methodology and to account for the decline in window service volume. Id. at 10-14. Non- acceptance variability is proposed to be updated to correct an implicit variability for non-acceptance costs of 100 percent. Id. at 14-15. Impact. The proposed changes would decrease the affected variabilities, which would cause a corresponding decrease in volume variable window service costs. See id. at 15-17. The claimed impacts on window service costs are: ---------------------------------------------------------------------------------------------------------------- Established Proposed unit Unit WS cost Product unit WS cost WS cost change ---------------------------------------------------------------------------------------------------------------- First-Class Mail................................................ $0.007 $0.003 -$0.004 USPS Marketing Mail............................................. 0.002 0.001 -0.001 Periodicals..................................................... 0.0014 0.0006 -0.0008 Package Services................................................ 0.049 0.028 -0.021 Domestic Competitive Products................................... 0.096 0.049 -0.047 Certified Mail.................................................. 0.652 0.431 -0.221 Money Orders.................................................... 2.032 0.978 -1.053 ---------------------------------------------------------------------------------------------------------------- Id. at 17. The claimed impacts on unit costs range from -0.3 percent to -.0 percent for First-Class Mail; -0.1 percent to -1.4 percent for USPS Marketing Mail; -0.1 percent to -0.7 percent for Periodicals; -0.1 percent to -2.5 percent for Package Services; -12.1 percent to -37.1 percent for Ancillary Services, and average -1.4 percent for domestic Competitive products.\2\ --------------------------------------------------------------------------- \2\ Id. at 20. For Market Dominant products, a full breakdown by product of the claimed impact on unit costs can be found in Table 2 in the Proposal. See id. ---------------------------------------------------------------------------
