5 terms

GRAT financial

"Represents an aggregate of 44,392 shares contributed from the GRAT of the Reporting Persons spouse."

Annuity Trust financial

"Represents 44,392 shares from the Jennifer Duda Annuity Trust to the Kenneth and Jennifer Duda Living Trust."

501(c) Foundation financial

"These shares are held by a 501(c) Foundation for which the reporting person and his spouse serve as co-trustee."

beneficial ownership financial

"The reporting person shares voting and investment control over the shares but disclaims beneficial ownership of the shares."

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.

co-trustee financial

"These shares are held by a family trust for which the reporting person is co-trustee."
