3 terms

dividend reinvestment financial

"These shares were purchased in connection with a dividend reinvestment through brokerage accounts."

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.

family limited partnership financial

"These securities are held by a family limited partnership, of which the Reporting Person is a general partner."

pecuniary interest financial

"disclaims beneficial ownership of the securities ... except to the extent of her pecuniary interest therein."
