|---|---|---|---|---|
| (a) Estimated net worth at the earliest available report (2014); the member entered office earlier, in 2011 | 2014 | −$194,979 | $107,510 | $409,998 |
| (b) Latest net worth estimate | 2025 | −$200,975 | $242,012 | $684,999 |
| (c) Estimated gain / loss, nominal dollars, 2014 → 2025 (11 years spanned) | 2014–2025 | −$610,973 | +$134,502 | +$879,978 |
Gain Low = latest Low − earliest High; Gain High = latest High − earliest Low (widest possible spread); Mid = latest Mid − earliest Mid.
Reliability flags (net worth): none for these two endpoints. Included in the recommended dollar-gain ranking.

- What this is: Net worth = Schedule A assets (each value range at its midpoint; low–high range shown) minus Schedule D liabilities (midpoints / ranges). Low = assets at range floors minus liabilities at range ceilings; Mid = midpoints; High = assets at ceilings minus liabilities at floors. Low and High are outer bounds of the reported ranges, not likely outcomes.
- What it excludes / understates: exact values (only ranges are reported); a personal residence is not reported as an asset (although a mortgage on it may be listed as a liability, which then lowers the estimate); retirement and federal accounts (e.g. Thrift Savings Plan, defined-benefit pensions) are only partly or not reported; assets of excepted/blind trusts, cash held below reporting thresholds, vehicles, household goods and most spouse/dependent items exempt from reporting are not included; liabilities on a personal residence, revolving credit under thresholds and loans to family may be omitted by filers.
- Open-ended top ranges (e.g. “Over $50,000,000”) are counted at their lower bound and flagged, so such values are understated.
- The change is a change in estimated net worth in nominal dollars (no inflation adjustment). It includes salary, gifts, inheritances, business income and re-valuation as well as investment results, and it is subject to range-bracket noise; it is not an investment return and implies nothing about conduct.
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.

Sensitivity band for the average (all ranges at floor vs. all at ceiling, same holdings both years): +5.5% to +4.8%. 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)
- 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.
- 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.
- 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).
- 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).
Limitations
- Ranges are wide (up to a factor of 5 or more, and up to $50M+ open-ended); a holding can move between ranges without any real change in value, and stay in a range while moving materially. Yearly estimates are therefore noisy; the “strict envelope” shows the mathematical worst/best case and is typically wider than ±100%.
- Purchases and sales are only disclosed as ranges and only for transactions over $1,000; partial sales, dividend reinvestment, spousal/dependent accounts and retirement-plan funds are reported inconsistently. Excepted/blind trusts, personal residences and certain pensions are not reported at all.
- Filers sometimes change how they list assets (e.g. listing a brokerage account vs. its individual holdings), which can make positions untraceable across years; these are excluded rather than guessed.
- Asset values in an annual report are as of Dec 31 of the reporting year; the report year t−1→t covers that calendar year. Late or amended filings are used when filed; extensions can delay them.
- The text of these reports is machine-parsed from PDFs; parse errors are possible. Every number links back to the cited filing. This is not investment advice.
- Use of these filings is restricted by 5 U.S.C. § 105(c) (no unlawful, commercial or credit-rating purpose, and none for solicitation of money).
