weighted average price financial
"The price reported in Column 4 is a weighted average price."
Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.
IRA financial
"Common Stock reported as held indirectly through an IRA account."
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.
401K financial
"Common Stock reported as held indirectly through a 401K plan."
An employer-sponsored retirement savings plan in the United States that lets workers set aside part of their paycheck into investments with tax advantages; some plans also include employer matching contributions, which is like free money added to your savings. It matters to investors because 401(k) balances represent a large pool of household retirement assets that influence personal financial security, investor behavior, and long-term demand for stocks and bonds.
indirectly financial
"Shares are reported as held indirectly through retirement accounts."
