weighted average purchase price financial
"Represents the weighted average purchase price."
The weighted average purchase price is the average cost per share you paid across multiple buys, calculated so larger purchases count more than smaller ones. Imagine buying apples at different prices: the overall price you effectively paid depends on how many apples you bought at each price. Investors use it to measure true cost basis, calculate gains or losses, decide when to sell, and manage taxes and portfolio performance.
beneficial ownership financial
"Reporting Person disclaims beneficial ownership of such 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.
pecuniary interest financial
"except to the extent of his pecuniary interest, if any, therein"
Defined Benefit Plan financial
"nature_of_ownership: By Defined Benefit Plan"
A defined benefit plan is a retirement program that guarantees workers a specific monthly payment after they retire, with the employer responsible for funding whatever is needed to meet that promise. Investors care because these plans create long-term payment obligations that can affect a company’s cash flow and balance sheet—similar to a homeowner having a fixed mortgage the household must cover regardless of income swings.
IRA financial
"nature_of_ownership: By IRA"
An individual retirement account (IRA) is a savings account designed to help people put aside money for their retirement, often with tax advantages that encourage long-term savings. It matters to investors because it can grow over time, providing financial security later in life, and offers benefits that can reduce current taxes or allow investments to compound more effectively.
