dividend reinvestment financial
"Includes 11.168 shares acquired pursuant to 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.
administrative fee financial
"Also reflects the deduction of an administrative fee in the amount"
Rule 16a-11 regulatory
"not previously reported pursuant to Rule 16a-11"
401(k) Plan financial
"nature_of_ownership":"By 401(k) Plan""
A 401(k) plan is a workplace retirement account that lets employees set aside part of their pay into a tax-advantaged savings pot, often with employers adding matching contributions — like a workplace piggy bank for future income. It matters to investors because the amount people save and how employers fund these plans influence consumer spending, corporate payroll costs and the flow of money into financial markets, which can affect stock prices and company valuations.
