restricted stock unit awards financial

"partial settlement of two (2) restricted stock unit awards originally reported"

Restricted stock unit awards are company promises to deliver a specific number of shares to employees or service providers in the future once conditions—such as staying with the company for a set time or meeting performance targets—are met. They matter to investors because when the promises convert into actual shares they increase the total share count and can reduce earnings per share, while also aligning recipients’ interests with stock performance much like deferred pay that turns into ownership if goals are met.

dividend equivalents financial

"Includes 1,786.851 dividend equivalents accrued on unvested restricted stock units."

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.

economic equivalent financial

"Each dividend equivalent is the economic equivalent of one share of Cisco common stock."

payment of tax liability financial

"Represents shares withheld for payment of tax liability arising as a result"
