Restricted Stock Unit financial
"Represents matching restricted stock units allocated to the Reporting Person with respect to the Reporting Person's deferral of a portion of their annual base salary"
A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.
2018 Management Stock Purchase Plan financial
"pursuant to the Company's 2018 Management Stock Purchase Plan"
annual cash incentive compensation financial
"deferral of a portion of their annual base salary and annual cash incentive compensation"
fair market value financial
"equal to the fair market value of one share of the Company's common stock"
The price a willing buyer and a willing seller would agree on for an asset or security when neither is under pressure and both have access to the same information. Think of it as the market’s neutral estimate of what something is worth, like the price two neighbors would settle on for a car after comparing similar listings. Investors care because fair market value guides buying and selling decisions, tax reporting, portfolio valuation, and how accurately company assets are reflected in financial statements.
vesting commencement date financial
"prior to the fifth (5th) anniversary of the Reporting Person's vesting commencement date"
The vesting commencement date is the starting point when an employee begins earning ownership rights to their promised benefits, such as stock options or retirement contributions. Think of it like the day a savings account is opened—only after this date do the benefits start to grow and become fully available over time. It matters to investors because it marks when the clock begins ticking toward full ownership, affecting the timing and value of these benefits.
