Largest first, capped at 40 line items. Each is the asset's reported value bracket, not the income it produced.

From annual financial disclosures, which report every asset and debt as a bracket — so these are ranges, and the figure shown is their midpoint. A primary residence is not a reportable asset while its mortgage is a reportable debt, which pushes some members negative. How this is calculated →
