Metris Lens

Making private markets
observable.

Metris Lens provides the first position-level benchmarks for unlisted BDCs, built entirely from mandatory SEC filings. Independent, rules-based, transparent, and reproducible.

Why this exists

Private credit is the fastest-growing asset class in wealth management. Unlisted BDCs have grown from a niche product to a core allocation for advisors and institutions. Yet performance measurement has lagged far behind the assets under management.

Existing benchmarks rely on voluntary manager surveys that cover a fraction of the market, or track only listed BDCs whose market prices reflect trading dynamics rather than portfolio performance. There has been no comprehensive, rules-based benchmark for the unlisted BDC universe -- until now.

By sourcing all data from mandatory portfolio disclosures filed with the SEC, Metris Lens provides complete, unbiased coverage of the unlisted BDC market. Every position in every fund's schedule of investments becomes a data point. No voluntary submissions, no selection bias, no gaps.

Principles

Independent

No voluntary manager surveys. No proprietary feeds. All data comes from mandatory SEC filings, eliminating selection bias.

Rules-based

Fully systematic construction with no discretionary overrides. Every classification, matching, and aggregation step follows published rules.

Transparent

Coverage gaps are disclosed inline. Data quality metrics are published. The methodology is open and documented.

Reproducible

Given the same SEC filings, anyone can reproduce the index. The pipeline is deterministic with published validation.
