restricted stock units ("RSUs") financial

"These reported securities represent restricted stock units ("RSUs") granted on July 31, 2026"

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.

deferred stock units ("DSUs") financial

"The reported securities include (a) 17,429 deferred stock units ("DSUs") granted under the Issuer's 2012"

Incentive Compensation Plan financial

"RSUs granted on July 31, 2026 under the Issuer's 2024 Incentive Compensation Plan"

An incentive compensation plan is a formal program that rewards employees and executives with bonuses, stock, or other payments tied to specific performance goals—such as revenue, profit, productivity, or long‑term share price. Investors watch these plans because they shape how leaders make decisions and take risks; like paying a coach by wins rather than effort, well‑designed plans can drive sustainable growth while poor designs can encourage short‑term behaviors that harm shareholder value.
