Stock Option (right to buy) financial
"security_title is reported as Stock Option (right to buy) for three grants"
weighted average sales price financial
"This is the weighted average sales price representing 239,850 shares sold"
Employee Stock Purchase Plan financial
"Includes 141 shares acquired through the Company's 2018 Employee Stock Purchase Plan"
An employee stock purchase plan is a company program that lets workers buy shares through small payroll deductions, often at a discount to the market price and after a set offering period. Think of it like a workplace savings plan that turns into ownership: it encourages employees to share in the company’s success and can create predictable buying or selling of stock that investors watch because it affects supply, demand and employee incentives.
vesting schedule financial
"The options became exercisable based on the following vesting schedule"
A vesting schedule is a timeline that determines when someone gains full ownership of certain benefits, such as company stock or retirement contributions. Think of it like earning the right to own a gift gradually over time, rather than receiving it all at once. It matters to investors because it affects when they can fully access or sell these benefits, influencing their financial planning and decision-making.
