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.
Directors Deferred Compensation Plan financial
"Held in Directors Deferred Compensation Plan."
A directors deferred compensation plan lets a board member postpone receiving part or all of their cash fees or stock-based pay until a future date, often retirement, allowing taxes to be delayed and payouts to be structured over time. Investors care because these plans change a company’s future cash obligations and reveal how the board’s pay is aligned with long-term performance—like choosing to take a paycheck later to tie personal reward to the company’s future results.
