Key Terms

3 terms

weighted average financial

"The price in Column 4 is a weighted average of shares purchased"

A weighted average is a way of calculating an overall number when some items matter more than others by giving each item a different level of importance, or weight. Investors use weighted averages to combine figures like prices, returns or earnings so the result reflects the size or significance of each part — like grading a class where a final exam counts more than a quiz, producing a score that better represents true performance.

deferred stock units ("DSUs") financial

"2,218 unvested shares underlying deferred stock units ("DSUs"); and 54,712 shares"

beneficially owns financial

"After this purchase, Errico beneficially owns 343,332 shares"

Beneficially owns means a person or entity enjoys the economic benefits and control of a security even if the legal title or registration is held in another name. Think of it like having the keys and profits from a car that is registered to a friend: you use it, benefit from it, and make decisions about it even though the official paperwork lists someone else. For investors, this matters because it reveals who truly controls shares, affects voting power, potential conflicts of interest, and regulatory disclosure obligations.
