% of shares outstanding suppressed: the summed institutional 13F holdings (13,318,299) exceed the cover-page shares-outstanding count for this quarter (100, as of 2026-03-31) by more than securities-lending double counting can explain (FINRA short interest 2,184,362 shares at 2026-04-30), so the share count is stale or wrong (common for annual 20-F foreign private issuers after a share issuance) and a percentage would be fabricated. Holder share counts are shown as filed.
Crowding percentile withheld — no market cap for CLBK in the served universe — the cohort is size-matched, and an unmatched percentile would compare a micro-cap register to a mega-cap one.

† a filer this large appearing as NEW usually reflects a renamed or succeeded filing entity (the old name stops filing the same quarter) — not a brand-new position.
Rows rank by the value each filer reported — 13F filers price their own positions, so a holder with fewer shares can rank just above one with more.

Shares reported each quarter by the largest current holders. Green = added vs the prior filing, red = trimmed, grey = roughly held; a dash is a quarter with no 13F on file (a gap is skipped, not read as an exit). 13F is filed up to 45 days after quarter-end. Up to 40 quarters (10 years) available — use the selector above.
Line breaks are honest gaps — quarters with no 13F record, or a suppressed % — never interpolated. % of shares outstanding divides each quarter's as-filed 13F shares by the SEC cover-page share count dated to that same quarter (split-adjusted), not by today's count — so splits and buybacks don't move the line.

Source: SEC Form 13F — every institution manager (≥ $100M in 13F securities) reporting a long US-listed position, across ~10,250 filers over 10 years of history. 13F is long-only, US-listed, filed up to 45 days after quarter-end.

The 2025-Q4 register is as-filed in ITS OWN share basis; every count below was rebased into the 2026-Q1 basis (no split in between, factor 1). Dollar figures value the SHARE delta at one price — the 2026-03-31 close — rather than differencing two filings' own reported values, which would mix the quarter's price move into the trade figure.
13Fs disclose LONG US-listed positions only — shorts, most derivatives, bonds and non-US listings are invisible here, and a filer's quarter-over-quarter change is not necessarily a trade (index rebalances, in-kind transfers and entity successions all read as flow).
