4 terms

Restricted Stock Program financial

"Acquired through the Company's Restricted Stock Program. Shares vest equally on anniversary"

beneficial ownership financial

"The beneficial ownership amount reported herein reflects a 26-share adjustment"

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.

stock splits financial

"26-share adjustment to reconcile the reporting person's holdings following prior stock splits"

A stock split increases the number of a company’s shares by dividing existing shares into multiple smaller pieces, like slicing a pizza into more slices without adding more pizza. Each shareholder keeps the same overall ownership and value, but each share becomes cheaper and more plentiful, which can make the stock easier for everyday investors to buy, potentially boost trading activity and change how price movements look on charts.

indirect ownership financial

"Common Stock held indirectly Through Basic Management Company Inc."
