5 terms

weighted average price financial

"The price reported in Column 4 is a weighted average price."

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.

beneficially own financial

"LMAM may be deemed to beneficially own these securities as the investment adviser to those funds."

Beneficially own means having the economic rights and risks of a security—such as the right to receive dividends, sell the shares, or profit from price changes—whether or not your name appears on the official share register. Think of it like renting a car: you use it and reap the benefits even if the title lists someone else. Investors care because beneficial ownership determines who truly controls value, must be disclosed under securities rules, and can signal potential influence or trading activity that affects a stock’s price.

control persons financial

"Daniel Lau and Christine Man are control persons of LMAM and may be deemed to beneficially own these securities."

pecuniary interests financial

"They disclaim beneficial ownership of such securities except to the extent of their respective pecuniary interests therein."

ten percent owner financial

"Reporting persons are indicated as ten percent owners in the Form 4 metadata."
