Disposition to issuer financial

"the 511-share transaction as a disposition to the issuer"

Stock Units financial

"He exercised 1,381 Stock Units at $0.00 per unit"

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.
