beneficial ownership limitations financial
"subject to certain beneficial ownership limitations"
Beneficial ownership limitations are rules or contractual caps that restrict how much of a company’s stock an individual or entity can be treated as owning or controlling for legal, regulatory or corporate-governance purposes. They matter to investors because such limits affect voting power, reporting obligations, takeover risk and the ability to increase a stake — like an elevator weight limit or a lane divider that prevents any one car from taking over the whole road.
pecuniary interest financial
"except to the extent of their respective pecuniary interest"
