Who owns Associated Clinical Laboratories of Pennsylvania, L.L.C.
One company in the researched set discloses a stake in Associated Clinical Laboratories of Pennsylvania, L.L.C., none of it sized by anyone who discloses it. Associated Clinical Laboratories of Pennsylvania, L.L.C. is private, so no 13F reports it: a 13F covers exchange listed positions only. These figures exist because each holder disclosed the stake in its own filings.
What this is
A Pennsylvania holding company whose only recorded function is to hold the one percent general partner interest in Associated Clinical Laboratories, L.P., the Erie reference laboratory partnership, and it appears in no public record other than the subsidiaries and joint ventures exhibit to Quest Diagnostics' own annual report.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.
- Quest Diagnostics Incorporated. Exhibit 21.1 lists 'Associated Clinical Laboratories of Pennsylvania, L.L.C. (PA)' at 53.5%, written here as 53.5, not 0.535. This entity itself holds a further 1% of Associated Clinical Laboratories, L.P. (the next row), so Quest's fully indirect interest in that LP is very slightly larger than the 52.97% stated directly for it; see that row's method_note. source
What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of Associated Clinical Laboratories of Pennsylvania, L.L.C. where a holder stated one, and are missing where no holder did.
