beneficial ownership financial

"filed an initial statement of beneficial ownership for Boudewijn Duinstra"

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.

reporting person financial

"The reporting person is Boudewijn Duinstra, designated as EVP, Chief Risk Officer"

Form 3 regulatory

"This Form 3 filing identifies Boudewijn Duinstra as an insider"

Form 3 is the initial public filing that officers, directors and large shareholders must submit to report their ownership of a company’s securities when they become insiders. It acts like an opening inventory sheet that gives investors a starting point to see who holds significant stakes and to spot later trades or potential conflicts of interest, helping assess insider confidence and transparency.
