Restricted Stock Units financial

"Restricted Stock Units (RSUs) granted under the Issuer's Incentive Plan."

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.

Incentive Plan financial

"RSUs granted under the Issuer's Incentive Plan."

Deferred Compensation Plan financial

"have been deferred under the Issuer's Deferred Compensation Plan for Non-Employee Directors."

A deferred compensation plan is an arrangement where an employer agrees to pay part of an employee’s pay or bonus at a later date instead of immediately, often to reduce current tax bills or to tie rewards to long-term performance. For investors it matters because these promises create future cash obligations and influence executive incentives and retention; they can affect a company’s reported liabilities, cash flow planning and the risk profile if the business faces financial trouble.

Non-Employee Directors financial

"Deferred Compensation Plan for Non-Employee Directors."

Non-employee directors are board members who do not work for the company as salaried employees and usually do not hold day-to-day management roles. They act like outside referees or independent coaches, providing oversight, asking tough questions, and protecting shareholders’ interests; investors care because these directors help ensure management is accountable, reduce conflicts of interest, and influence decisions that affect company strategy and long-term value.
