restricted stock units financial
"Represents restricted stock units in lieu of cash compensation of $25,375"
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
voting and dispositive power financial
"has sole voting and dispositive power with respect to the shares held"
general partner financial
"RRE Ventures GP V, LLC is the general partner of RRE Ventures V, L.P."
A general partner is the person or firm that runs an investment partnership and legally represents it — they make the day-to-day decisions, choose which assets to buy or sell, and are responsible for the partnership’s obligations. Investors care because the general partner’s judgment, risk-taking and fee and profit-sharing arrangements determine both the potential returns and the level of exposure to losses; think of the GP as the ship’s captain whose skill and honesty shape the voyage’s outcome.
pecuniary interest financial
"Mr. Porteous disclaims beneficial ownership ... except to the extent of any pecuniary interest therein."
beneficial ownership financial
"Mr. Porteous disclaims beneficial ownership of the reported 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.
