The Pension Benefit Guaranty Corporation (PBGC) is seeking an independent contractor to conduct a targeted peer review of its Single-Employer (SE) and Multiemployer (ME) PIMS forecasting models. The review will cover the current versions of both models, excluding the legacy SE PIMS, and is scheduled to take place in 2026-2027. The focus will be on the assumptions and methods these models use to incorporate the financial health of plan sponsors in projections. PBGC welcomes suggested refinements based on the contractor’s expertise and will allow subcontracting as needed to accomplish the review.
