Deferred Stock Units financial

"Each deferred stock unit represents the right to receive one share of Cullen/Frost Bankers, Inc. common stock."

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.
