Key Terms

restricted stock units financial

"Award of restricted stock units granted pursuant to the Kilroy Realty 2006 Incentive Award 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.

dividend equivalents financial

"Each restricted stock unit carries with it a right to receive dividend equivalents in respect of the share."

Payments tied to employee or contractor equity awards that mirror the cash dividends paid on the company’s stock; they give the holder the same economic benefit as owning the shares without transferring actual shares—often paid in cash or additional award units when the award becomes payable. Investors care because these payments affect a company’s compensation costs, cash flow and potential share dilution, and they signal how management is being rewarded and aligned with shareholders.

Incentive Award Plan financial

"granted pursuant to the Kilroy Realty 2006 Incentive Award Plan."

An incentive award plan is a formal program that rewards employees, executives, or directors with cash, stock, options, or other pay when the company meets set goals or performance targets. Like a sales commission or a loyalty program that pays out when you hit milestones, it’s designed to align staff behavior with company objectives; investors care because it affects a company’s costs, share count (dilution), leadership incentives, and long-term value creation.
