In the latest Fast Fact, the Public Retirement Research Lab Database is used to assess the impact of Section 603 of the SECURE 2.0 Act on public-sector retirement plan participants. While the percentage of public-sector participants affected by this mandatory provision is relatively low, the percentage of the public-sector plan sponsors in the database impacted is much higher at 55 percent, as these participants are dispersed across many plans. In other words, 1 in every 2 plan sponsors may be required to make plan administration changes as a result of this provision.
