Read this first. Members report asset values only as ranges (e.g. “$15,001 – $50,000”), never exact dollars. Every figure below is an estimate computed from range midpoints, not a measured return. Figures cannot be interpreted as investment performance, and they do not show wrongdoing or skill. Methodology and limitations are at the end and in the project README.

Reliability flags: few years (4).

Sensitivity band for the average (all ranges at floor vs. all at ceiling, same holdings both years): -31.4% to -19.2%. This band is narrow because it moves both years together; the true uncertainty is larger — see the per-year “strict envelope” column and the limitations.

Filings used

Each annual-report year uses one filing (most recently filed version among originals/amendments whose Schedule A row count is ≥ 40% of the largest). Electronic (text) PDFs are parsed. Scanned/image-only filings are OCR-read and used only if they pass the explicit validation gates described in the project README (value/income coverage, two-engine agreement, exact bracket snapping, page completeness, year-to-year position continuity); such years are labelled OCR-derived below. Scanned filings that fail validation are listed as “insufficient data – scanned”.

Method (summary)

  1. Schedule A asset rows are read from each annual report; the dollar range for each row is converted to its midpoint. Open-ended top ranges (“Over $50,000,000”) are excluded from the traced set and counted as a coverage loss.
  2. Positions are matched year to year by owner code (self/SP/DC/JT) + normalised asset name. A position that appears only in year t is included only if Schedule B shows a purchase of it in year t (opening value 0); a position that disappears is included only if Schedule B shows a sale (closing value 0). Otherwise it is excluded as unexplained.
  3. Estimated gain = (closing − opening + reported income − purchases + sale proceeds) ÷ opening, all at midpoints, for the traced positions. “Capital gains” income is not added again (it is already in value change and sale proceeds).
  4. A year counts only if traced opening value ≥ $50,000 and traced coverage ≥ 60% of the opening midpoint. A member is ranked only with ≥ 3 such years (exactly 2 = “limited data”, shown but unranked). Average = geometric mean of (1+yearly estimate).
