Identity floor
Borrower identity here is a normalised-name match — the majority join in the private-credit books, with roughly 10% measured error in each direction (two companies fused into one, or one company split across spellings). Figures built on it — crowding, overlap, the manager complex — are floors, not exact counts. How this is measured →
Fair value and share of that fund's resolved holdings book, each at the fund's own most recent reported period — the as-of column, because the holders of one company do not file on one date. The bar under each fair value is that fund's share of the $94M combined total across every holder — a different denominator from the share-of-book column — so one dominant lender vs an even syndicate is visible without reading the dollar figures.

The range across reported debt positions in the same borrower — fair value over amortized cost as filed — for 11 funds holding it in Q1'26.
11 funds · 30 positions · Q1'26
Instrument stated on 11 of 30 positions (37%). With most positions untagged, the range above may reflect capital structure — a junior tranche marked down beside a senior one held whole — rather than funds disagreeing on this borrower.
Positions counted here filed a principal balance — the debt proxy used to find comparable marks, measured 82% precise as actual debt where an instrument label exists; the rest are equity or warrants filed with a principal amount.
