Non-Employee Director Compensation Program financial
"The shares were issued pursuant to the Issuer's Non-Employee Director Compensation Program."
Restricted stock units ("RSUs") financial
"Restricted stock units ("RSUs"). The Reporting Person is entitled to receive one (1) share of Common Stock for each one (1) RSU upon the vesting thereof."
Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.
pecuniary interest financial
"disclaims beneficial ownership of such shares, except to the extent of his actual pecuniary interest therein."
stock option financial
"The option was issued pursuant to the Issuer's Non-Employee Director Compensation Program."
A stock option is a contract that gives you the right to buy or sell a company's stock at a specific price within a certain time frame. People use them to potentially make money if the stock's price moves favorably or to protect against losses. It's like holding a coupon that can be used to buy or sell stock at a set price later on.
vesting financial
"The option vests with respect to 1/12th of the shares subject thereto on each monthly anniversary of the grant date, which vesting will accelerate in full"
Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.
