What SpreadVista tracks for PTMN

•Marks-to-par across the portfolio. Fair value as a fraction of par cost — the canonical health signal for a private-credit position — read from PTMN's own iXBRL tags and tracked quarter-over-quarter. A mark needs a par basis to exist, and PTMN reports one on 60.8% of the positions we serve; the rest (equity stakes, warrants, untagged principal) are shown without one rather than estimated.
•Non-accrual positions. The PTMN positions we tied to a non-accrual disclosure in the filer's own footnotes, and the dollar exposure behind them. A position is flagged only where the filing says so — every other position is carried as unknown, never as performing — so read this as a floor on PTMN's non-accruals, not a complete list.
•Top issuers by fair value. PTMN's concentration profile — the largest 10/25/50 exposures with mark and maturity context.
•Spread surface vs comparable BDCs. Where PTMN's positions sit on the credit-spread surface relative to peer-group BDCs holding similar credits, across the 51.3% of its positions that carry a tagged spread over a reference rate.
•Cross-vehicle issuer exposure. Which other BDCs and interval funds hold the same credits as PTMN — a contagion-risk view incumbents charge $20K–200K per seat for.

What we can't show for PTMN

SpreadVista only serves what the filer machine-tagged, and only computes a metric where there is enough of it to stand behind. Each item below is either under that bar for PTMN or something we could not tie to any individual position — the note says which. We leave them blank rather than infer them:

•NAV per share. We have no NAV-per-share observation for PTMN. Non-traded BDCs report NAV outside the tagged Schedule of Investments, so it doesn't reach us through the same pipeline as the positions.
