Deferred Restricted Stock Units financial
"The filing lists "Deferred Restricted Stock Units" as a derivative security title."
Deferred restricted stock units are promises by a company to give employees or executives company shares at a future date, subject to conditions like continued employment or performance targets; the delivery and tax event are intentionally delayed. They matter to investors because they affect when new shares may be issued and how executives are motivated—like a paycheck held in escrow that vests over time, influencing potential share dilution and management behavior.
Director Deferred Compensation Program financial
"The DRSUs will settle pursuant to the issuer's Director Deferred Compensation Program."
A director deferred compensation program is an arrangement that lets a company delay paying part of a board member’s fees or bonuses until a future date, often at retirement or after leaving the board. It matters to investors because it affects a company’s long‑term cash commitments and executive incentives—like a timed savings plan that can align directors’ decisions with the company’s future performance while creating future liabilities on the balance sheet.

"Settlement occurs under the issuer's Director Deferred Compensation Program and 2023 Stock Incentive Plan."
