vesting financial
"The option vested or vests as to 1/48th of the total award monthly"
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.
award agreement financial
"Pursuant to the terms of the reporting person's award agreement with the Issuer"
An award agreement is a legal contract that spells out the terms of a pay or equity grant—such as stock options, restricted shares, or cash bonuses—given to an employee, director or consultant. It describes what is being granted, any conditions for keeping it (for example, earning it over time or meeting performance targets), and what happens if the person leaves or breaks rules. Investors care because these agreements affect company costs, potential share dilution and how executives are motivated and rewarded.
continued service financial
"subject to the reporting person's continued service to the Issuer on each vesting date"
