Frequently asked questions

Where does this data come from?
Every figure is derived from public SEC filings — BDC quarterly reports and related datasets published on SEC EDGAR. Nothing comes from paid pricing feeds or private sources, and every number can be traced back to the filing it appeared in.
What is the peer consensus?
When two or more BDCs hold the same loan, each reports its own fair-value mark in its own SEC filing. MarkQuality lines those marks up: the median of the other holders' marks is the peer consensus for that position.
Is this a rating or an opinion on the fund?
No. MarkQuality does not issue fair-value opinions and does not claim any mark is wrong or any NAV is overstated. It measures how consistently a fund's marks track the peer consensus — a difference can reflect legitimate factors like position size, timing, lot, structure, or valuation methodology. It is analytics on public data, not investment advice.
What do I get with a free account?
The full Mark Discipline scorecard for every tracked BDC — position-level comparisons against peer marks, quarter-over-quarter history, a change feed, and watchlist alerts. Free during the beta, no card required.
How often is the data updated?
Quarterly, following the SEC filing cycle: after each reporting season the newly filed marks are ingested, re-clustered, and the peer comparisons recomputed.
How the comparison worksSEC EDGAR filings
Every figure on this page is the fund's own number as reported in its public SEC filings. MarkQuality compares each BDC's marks with the cross-BDC consensus on the same loans; only marks the pipeline rates usable feed the peer medians. The comparison measures how consistently a BDC's marks track the peer consensus — it is not a judgment of the accuracy or good faith of any fund's valuations. Verify every figure against its source filing. Independent comparison on public data, not investment advice.

Every mark referenced on MarkQuality is the holder's own figure as reported in its SEC filing, shown side by side against the peer median — not a fair-value opinion, nor an assertion that any mark is wrong or that net asset value is overstated. A gap from the median can reflect legitimate differences in position, timing, lot, structure, or valuation methodology rather than mispricing. Informational only — not investment advice.
