Fee Deferral Plan for Directors financial

"were acquired pursuant to the Issuer's Fee Deferral Plan for Directors"

restricted stock units financial

"defer receipt of 7,832 restricted stock units into an equal number of stock equivalents"

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

stock equivalents financial

"Additional stock equivalents accrue as and when dividends are paid"

dividend reinvestment transactions financial

"acquired since the Reporting Person's last filing on Form 4 from dividend reinvestment transactions"

Section 16 of the Securities Exchange Act of 1934 regulatory

"dividend reinvestment transactions exempt from Section 16 of the Securities Exchange Act of 1934"

A provision of federal securities law that requires company insiders—directors, officers and large shareholders—to publicly report their stock holdings and trades and to surrender any “short-swing” profits from purchases and sales within a six-month window. It acts like a rule that forces leaders to announce their trades and prevents quick buy-sell windfalls, giving investors transparency into insider activity and reducing opportunities for unfair gain.
