3 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.

beneficiary and trustee other

"of which the reporting person is beneficiary and trustee."

ten percent owner regulatory

"The reporting person is identified as a ten percent owner of the issuer."
