2026-Q2 still filling — 4/25 books ($4M); marked on the axis, not plotted.
The dollar figure is a lower bound. Tracked passive dollars = the sum of the position's disclosed market value across every tracked book whose period end falls in that calendar quarter. N-PORT reports position value in USD. A LOWER BOUND on passive ownership — 25 tracked funds, not the whole passive complex — and the contributing books carry different period ends inside the quarter, so it is a sum of snapshots, not a single-date figure.
The percentage is split-adjusted. % of market cap = those dollars ÷ (the stored close at the quarter end × the SEC cover-page share count vintage-matched to that quarter and rebased into the close's own split basis). Stored closes are split-adjusted to today while a cover count is as-filed for its vintage, so rebasing both onto one basis is what keeps the series comparable across a split — the same convention the OWN tab's %-of-shares-out denominator uses, from the same module.
Recent quarters fill in late. Each quarter names how many of the tracked funds actually FILED a book in it. Fund calendars differ (SSGA files Mar/Jun/Sep/Dec, iShares Jan/Apr/Jul/Oct), so the newest quarter is always partial until the late filers land — a partial quarter's dollars are not comparable to a complete one's and are flagged rather than plotted as a collapse.
Pre-2019 data is kept separate. The pre-2019 leg is deliberately NOT aggregated into the footprint. Its books are a reconstruction whose per-book coverage runs 0.65–1.00, only some funds are present in any quarter, and identity-withheld rows mean absence is not evidence of non-membership — so a dollar total over it is not comparable to the N-PORT panel's. It is reported as what it is: observations, with their count, span and disclosed dollars. For ACIW the reconstruction holds 33 identity-established observations across 5 funds, 2013-03-31 → 2019-06-30.

Entry and exit are ranges, not exact dates. A book is a snapshot at the issuer's own period end, so an entry or exit is a BRACKET between two consecutive books — never an effective date.
Value held is a lower bound. Sum of the position's disclosed market value in the LATEST book of each holding fund. A LOWER BOUND on passive ownership — 25 tracked books, not the whole passive complex — and the books carry different period ends, so it is a sum of snapshots, not a single-date figure. Funds whose filing left the value blank are excluded from the sum and counted separately.
The pre-2019 data is scattered observations, not confirmed membership. Pre-2019 books are a reconstruction from Form N-Q / N-CSR HTML Schedules of Investments, which print a company NAME and no identifier; identity comes from a corroborated normalized-name join gated by a 2% price reconciliation, and unresolved or era-symbol rows are withheld. Absence from a pre-2019 book is therefore NOT evidence of non-membership, so no entry, exit or membership run is inferred on this leg — only the weight observations whose identity was established.
Coverage is shown per book (hover a weight): a book whose filing left part of its portfolio unmapped can understate a small position. Fund and index labels are editorial reference text for readability; every weight, value, rank and date comes from the filings alone.
