deferred stock units financial
"Represents the Reporting Person's deferral of his quarterly cash compensation into deferred stock units ("DSUs")."
Deferred stock units are promises from a company to give an employee shares of stock at a future date, often after certain conditions are met or after leaving the company. They function like a form of delayed compensation, allowing employees to earn shares over time. For investors, they represent potential future ownership in the company, but do not provide immediate voting rights or dividends until the shares are actually received.
DSUs financial
"The number of DSUs is calculated based on the closing price of the Common Stock on their date of issuance."
DSUs, or Deferred Share Units, are a form of long-term pay where employees or directors receive a promise of company shares or cash at a later date instead of immediate salary. Think of them as an IOU for future stock that vests over time and converts into actual shares or cash, so they matter to investors because they can increase the number of outstanding shares (dilution) and reveal how management’s pay is tied to company performance.

FAQ

What insider transaction did TER director Paul J. Tufano report?

Paul J. Tufano reported acquiring 116 Common Stock-equivalent shares as a compensation grant. The transaction reflects a deferral of his quarterly cash director fees into deferred stock units rather than an open-market purchase, increasing his directly held position to 65,848 shares.

How many TER shares does Paul J. Tufano hold after this Form 4?

After this transaction, Paul J. Tufano directly holds 65,848 shares of Teradyne Common Stock. The increase comes from 116 deferred stock units issued in lieu of cash compensation, which will convert into shares when he is no longer a non-employee director.

Was Paul J. Tufano’s TER transaction an open-market stock purchase?

No, the filing shows a grant-type acquisition at a price of $0.00 per share. The 116 units represent deferred stock units issued from his quarterly cash director compensation, not an open-market purchase of Teradyne shares on a stock exchange.

What are deferred stock units (DSUs) in the TER Form 4 filing?

Deferred stock units are share-equivalent units issued instead of cash compensation. For Paul J. Tufano, the number of DSUs is based on Teradyne’s closing stock price on the issuance date and will be settled one-for-one in Common Stock when he leaves the board.

When will Paul J. Tufano’s TER deferred stock units be settled?

The deferred stock units will generally be settled within ninety days after he no longer serves as a non-employee director. At that point, each DSU converts one-for-one into Teradyne Common Stock, turning the deferred compensation into actual shares.
