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.

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.
