Peer Review for Default Investment Safe Harbor Regulation

This document is about the peer review charge for certain "highly influential scientific assessments" related to the promulgation of a Notice of Proposed Rulemaking to create a regulatory safe harbor for the investment of participant contributions to participant-directed individual account pension plans when participants fail to provide investment direction. It outlines the specific questions for the peer reviewers to evaluate, such as the adequacy of the PENSIM model, the reasonableness of the high and low-impact scenarios, and the assumptions regarding asset allocation and rates of return. The peer reviewers are requested to evaluate the scientific validity, relevance, and utility of the estimates and the scientific information on which they are based, while avoiding providing advice on the policy decisions contained in the proposed rulemaking.
