| The reviewed ticker for the filed issuer name and share class, the same mapping the Reported positions table uses. Symbols are never inferred from names; — means no reviewed mapping. | position matched across quarters by exact reported CUSIP over a registry gap — never a name match | NEW / ADD / TRIM / EXIT by share count · NO CHANGE = same shares; the value moved with price, so never an ADD or a TRIM · EXIT = absent this quarter (disposed, delisted, confidential, or reported by an affiliate) — the filing does not say which · NO PRIOR = no comparable prior quarter on record (a first filing, or a quarter filed inside an affiliate's report), so not called a new stake · n/c = not classifiable: value undisclosed on one side of the pair, or neither shares nor value can classify it · †v: the reported share count is unchanged across the pair; this build's data classified the change from its reported value; builds from 2026-09-10 on read it as NO CHANGE | derived by Public Filings from the published data; “no value” means the source did not disclose a usable value — never zero | Prev value | Curr value | Prev shares | Curr shares | |

Open Champlain Investment Partners, LLC's 13F filings on SEC EDGAR ↗A 13F is a quarterly, long-only snapshot filed up to 45 days late — not current holdings. what a 13F covers ↗
13F reports cover LONG positions in Section 13(f) securities (US exchange-traded equities plus reportable options, warrants, certain convertibles) held by managers with at least $100M in such securities — so managers below that threshold are absent entirely. No short positions, no cash, no non-13(f) assets — not a full portfolio, and not a census of institutional ownership.
Positions are quarter-end snapshots filed up to 45 days late — not current holdings: a position may have changed or closed since the quarter ended.
Values are the manager's stated market value at quarter-end in era-dependent units (whole dollars for form versions effective 2023-01-03 onward, thousands before), normalized here to whole dollars; each record notes its original unit.
Affiliated managers may report the same position, so one position can appear under more than one filer.
Positions under confidential treatment may be omitted until a later amendment discloses them.
These are disclosures, not investment advice.
