beneficial ownership financial
"Reporting person disclaims beneficial ownership of shares 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.
pecuniary interest financial
"Disclaims ownership of investment entity shares except to the extent of his pecuniary interest therein."
401(k) plan financial
"Indirect ownership nature is listed as by 401(k) plan."
A 401(k) plan is a workplace retirement account that lets employees set aside part of their pay into a tax-advantaged savings pot, often with employers adding matching contributions — like a workplace piggy bank for future income. It matters to investors because the amount people save and how employers fund these plans influence consumer spending, corporate payroll costs and the flow of money into financial markets, which can affect stock prices and company valuations.
indirect ownership financial
"Ownership type is marked as indirect for spouse and investment entity holdings."
