Schedule of Assets

This is a pooled fund: many plans invest in it, and it holds the underlying securities.

Master trust / DFE filing
Pooled investment vehicle

This filing is a Direct Filing Entity (DFE) — a master trust or collective investment trust that pools assets from multiple participating plans. It does not have plan participants of its own, and the Plan Health Score formula doesn’t apply. Individual participant-facing plans that invest in this trust are the appropriate target for fiduciary analysis.

Cited interest vs pooled assets: cited interest sums what each participating plan reported holding in this trust, measured at that plan’s own year-end — and those filings span different years. Pooled assets is this single filing’s balance at one date. They’re independent measurements, so cited interest can land slightly above or below the pooled balance and won’t reconcile exactly.

Why no Schedule of Assets here? DFE holdings often live on the master trust’s own audited statement, not as a 4i schedule on the participating plans’ filings. We’re extending the parsing pipeline to cover DFE filings — see Methodology.
