"Amount reported includes: (i) 1,842 unvested restricted stock units or RSUs"
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.
performance stock units financial
"shares of restricted Common Stock received upon settlement of performance stock units or PSUs"
Performance stock units are a type of company award that grants employees shares of stock only if certain performance goals are met. They motivate employees to work toward specific company achievements, aligning their interests with those of shareholders. For investors, they can influence a company's future stock supply and reflect management’s confidence in reaching key targets.
deferred performance units financial
"and (iii) 89 vested deferred performance units or DPUs, which are Common Stock equivalents"
Common Stock equivalents financial
"89 vested deferred performance units or DPUs, which are Common Stock equivalents"
Common stock equivalents are financial instruments that can be converted into common shares or have a similar effect on a company's stock ownership, such as stock options or convertible bonds. They matter to investors because they can increase the total number of shares outstanding, potentially diluting existing ownership and affecting the company's stock value. Recognizing these equivalents helps investors understand the true potential for future share issuance and company ownership structure.
voting power and investment discretion financial
"Under the 2007 Olsem Family Trust, Reporting Person shares voting power and investment discretion"
