Key Terms

4 terms

weighted-average price financial

"Represents the average sale price. The actual sale prices range from $21.95 to $21.96 per share."

Weighted-average price is the average of multiple prices where each price is counted according to its size or importance—larger trades carry more weight than smaller ones, like averaging course grades by credit hours. It matters to investors because it gives a more realistic picture of the true price paid or received, helping assess trade execution, compare performance, calculate cost basis, and value positions more accurately than a simple average.

beneficially owned financial

"Reflects the amount of shares beneficially owned, including shares received due to automatic dividend reinvestment, as of the date of this report."

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

automatic dividend reinvestment financial

"Reflects the amount of shares beneficially owned, including shares received due to automatic dividend reinvestment, as of the date of this report."

employee stock ownership plan financial

"Indirect holdings reported through a 401(k) and an ESOP in Eastern Bankshares common stock."

An employee stock ownership plan (ESOP) is a company-run program that gives workers ownership stakes by allocating or letting them buy company shares, often through a retirement-style account. For investors, ESOPs matter because they align employees’ incentives with company performance—like turning staff into shareholders—which can boost productivity and long-term value but may also concentrate employee retirement savings in company stock, affecting financial risk and share demand.
