Deferred stock units (DSUs) financial

"Deferred stock units (DSUs) granted under the Alaska Air Group, Inc. (the "Issuer") 2016 Performance Incentive Plan"

Deferred stock units (DSUs) are a form of long-term pay that promises an employee or director future company shares or cash equal to the share value at a later date, usually after leaving the company or at a set vesting time. Think of them as a delayed paycheck tied to the stock: they align recipients’ interests with long-term share performance and matter to investors because they create potential future dilution and signal how management is rewarded and incentivized.
