What this guide establishes
- The analysis compares aggregate brackets, not individual merit or conduct.
- Total-asset concentration and the mix of real estate, deposits and securities are calculated separately.
- Values describe records at their disclosure dates, not present wealth or investment performance.

Bracket shares describe this disclosure sample. They do not measure investment returns, liquidity, conduct or present ownership.
Representative records grouped by disclosed name, institution and role
The report selects a latest representative record within each disclosed name, institution and role group. Historical rounds in the same group are not added together, but changes in affiliation or role may leave separate groups for the same person. The sample counts representative records, not a verified number of distinct people. Names alone are never grounds for merging records.
Publication and filing dates can differ across records. The latest included publication date does not mean every record was published on that date. Records are ordered by disclosed total assets and divided into the top 1%, 5% and 10%, with boundary counts rounded from the sample size. Counts and figures update when the published dataset changes.
Concentration and asset composition answer different questions
Concentration divides each bracket's disclosed total by the full sample total. Composition instead uses positive reported amounts for real estate, deposits, securities and vehicles. Debt is shown separately because it affects the net total differently.
The results are a way to form better research questions. They do not explain acquisition history, current ownership, returns or whether any holding is appropriate.
