"DEUs accrued upon the payment of a dividend"
restricted stock units (RSUs) financial
"time-vested restricted stock units ("RSUs")"
Restricted stock units (RSUs) are a type of company promise to give employees shares of stock in the future, usually after certain conditions like working for a set time. They are like a gift promised today that you receive later, which can become valuable if the company's stock price goes up. RSUs matter because they are a way companies reward employees and can be a significant part of compensation.

pecuniary interest financial
"except to the extent of the Reporting Person's pecuniary interest therein"
beneficial ownership financial
"disclaims beneficial ownership of these securities"
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.
