5 terms

restricted stock financial

"Represents shares of common stock acquired through the reinvestment of dividends received on restricted stock awarded to the Reporting Person"

Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.

non-cash compensation financial

"restricted stock awarded to the Reporting Person as non-cash compensation under the Simon Property Group, L.P. 2019 Stock Incentive Plan"

2019 Stock Incentive Plan financial

"as non-cash compensation under the Simon Property Group, L.P. 2019 Stock Incentive Plan"

charitable remainder trust financial

"nature_of_ownership: By Maxsim Charitable Remainder Trust"

beneficial ownership financial

"The Reporting Person disclaims beneficial ownership of these securities and the inclusion of these shares in the report shall not be deemed an admission"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.
