phantom share equivalents financial

"Phantom share equivalents acquired in the reporting person's"

non-qualified deferred compensation plan financial

"part of a multi-fund, non-qualified deferred compensation plan"

An arrangement where an employer agrees to pay part of an employee’s salary or bonus at a later date, often to attract or keep key staff. Think of it as a company IOU or a delayed paycheck held on the company’s books rather than in a protected retirement account; investors care because these promises create future cash obligations that are typically unsecured and depend on the company’s financial health, affecting risk, liabilities, and cash-flow planning.

dividend reinvestment financial

"accrued on September 4, 2026 through dividend reinvestment"

Dividend reinvestment is when the money earned from a company's profit sharing, called dividends, is automatically used to buy more shares of that company instead of being received as cash. This process helps investors grow their holdings over time without extra effort, much like using earned interest to buy more of a savings account. It encourages long-term investment growth by continuously increasing the amount of shares owned.
