stock units technical

"issued an equity award of 4,562 stock units"

Stock units are individual pieces of ownership in a company, like slices of a pie that together make up the whole business. They matter to investors because each unit represents a claim on the company’s assets, profits and sometimes voting power, and changes in the number or value of these units affect ownership percentages, potential dividends and share dilution — all of which influence an investment’s worth.

Payment Event technical

"each, a "Payment Event""

in-service distribution date technical

"an in-service distribution date elected by the reporting person"
