It is a floor: holdings at group companies the filing does not name are disclosed nowhere and are not included. The percentages are calculated, not filed, and carry their formula. equity_basis names which figure the denominator is, because filers report under Japanese, IFRS or US accounting standards and an adopter of the latter two stops tagging the Japanese consolidated figure — a parent-only denominator is a different measure and is labelled as one, never silently mixed with a group figure. Percentages are null where equity or total assets is missing or not positive; missing is never shown as zero.","scale_reference":"ISS's Japan proxy voting guidelines recommend a vote against the top executive at a company that allocates 20 percent or more of its net assets to cross-shareholdings, a policy effective from February 2022.

The denominator is the issuer's own reported issued shares less treasury shares, from its annual report nearest this holding's fiscal year end on either side — pct_basis_period_end gives that date, and it can fall after the holding's date where that report is the closer one. For a single-class listed stock this equals the stake's share of market capitalisation. It is null where the issuer files no annual report we hold; where the issuer's share count moves by half or more across the window, because a split or issue makes the share base indeterminate; and where the result would exceed 100%, which is a data fault rather than a stake. It is less exact where the issuer has more than one share class (pct_share_classes > 1), because treasury shares are reported across all classes.","holder_share_calc":"this position's book value ÷ the holder's shareholders' equity (or total assets) × 100, both as filed in the holder's own annual securities report","holder_share_note":"The mirror of pct_outstanding. That sizes a stake against the ISSUER — how much of the issuer this holder owns. pct_of_holder_equity and pct_of_holder_assets size the same position against the HOLDER: how much of its own capital is committed to this one name. Calculated, not filed. Null where the holder's filing gives no usable denominator, never zero. holder_equity_basis says which accounting figure the denominator is, and a parent_only basis is not comparable with a consolidated one. A position CAN legitimately exceed 100% of equity — a holder whose book equity is smaller than one long-held stake is a real and commercially interesting case, not an error — so no ceiling is imposed. Extreme values are worth checking against the filing: where the position's own two filed numbers are mutually impossible the row is marked `implausible`, but that test catches only scale errors visible per share, so it does not catch every bad figure. The book value and share count are returned alongside so the reader can check.","action_calc":"keyword match over the filing's own stated purpose and table footnotes: 株式分割、株式併合、株式交換、株式移転、会社分割、合併、持株会社、商号変更、公開買付、上場廃止","ratio_calc":"current shares ÷ prior shares where that ratio is an exact whole number (or its exact reciprocal) — the signature of a split or a consolidation rather than a trade","history":[{"year":"2022","period_end":"2022-03-31","named_holdings":68,"book_value_yen":74756000000},{"year":"2023","period_end":"2023-03-31","named_holdings":70,"book_value_yen":60567000000},{"year":"2024","period_end":"2024-03-31","named_holdings":64,"book_value_yen":94637000000},{"year":"2025","period_end":"2025-03-31","named_holdings":67,"book_value_yen":67460000000},{"year":"2026","period_end":"2026-03-31","named_holdings":47,"book_value_yen":69419000000}],"history_note":"One point per annual report filed.
