Implied mark
An implied mark is fair value divided by par for a fund holding, computed when the fund doesn't report a mark directly. Plain-English explanation of how implied marks make interval-fund holdings comparable to BDC marks.
An implied mark is a valuation ratio computed from a fund's disclosed numbers rather than reported directly by the manager: fair value divided by par (or principal) for each holding. BDCs report position-level fair value and cost in their Schedule of Investments, so their marks can be read straight from the filing. Interval funds and closed-end funds disclose holdings through monthly N-PORT filings, which report value and balance but not a headline "mark" — so the mark has to be derived. Value ÷ par gives the same cents-on-the-dollar figure a BDC would report, computed consistently across managers.
The reason implied marks matter is comparability. The same middle-market loan frequently sits in both a BDC and an interval fund at the same period-end. The BDC says it marks the loan at 97; the fund reports $9.7M of value against a $10M principal balance. Once the fund side is expressed as an implied mark of 97.0, the two vehicles become directly comparable — and any gap between them becomes visible. Without that normalization, cross-vehicle mark comparison is apples to oranges.
Implied marks come with caveats an analyst should know. Accrued interest treatment, partially-funded commitments, and currency conversion can each shift the ratio slightly, so a small divergence between a reported mark and an implied mark is often mechanical rather than a genuine valuation disagreement. Large or persistent divergence is the signal worth investigating.
SpreadVista computes implied marks for every N-PORT holding across 55+ credit-focused funds using one consistent methodology, labels them as implied wherever they appear (a methodology disclosure travels with the number), and places them side-by-side with BDC reported marks on every shared credit.
