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.

beneficial ownership financial

"The reporting person disclaims beneficial ownership of all securities held by spouse."

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

unitized stock fund financial

"Ownership is represented by units held in a unitized stock fund through the issuer's 401(k) retirement plan as of May 29, 2026."

401(k) retirement plan financial

"Ownership is represented by units held in a unitized stock fund through the issuer's 401(k) retirement plan as of May 29, 2026."
