Long-Term Benefit Trust

Governance body

No economic stake

Independent trust with the right to elect a portion of the board. A key governance factor for any future public listing.

Why the percentages stay fuzzy

• Much of Amazon's investment went in as convertible notes, so the final share count depends on conversion terms that have never been published.
• Multiple share classes with different voting rights mean economic ownership and control diverge sharply.
• The Long-Term Benefit Trust can elect board seats without owning economics — an unusual structure that public-market investors would need to price.
• Percentages only become authoritative in an S-1, which lists every holder above 5%.
