limit order financial
"transactions were effected pursuant to a limit order placed by the Reporting Person"
A limit order is an instruction to buy or sell a stock only at a specific price or better, giving you control over the exact price you pay or receive. It matters to investors because it acts like a price guard—similar to setting a maximum you’ll pay for an item at a store—so you avoid unexpected prices, though the trade may not happen if the market never reaches your limit.
weighted average price financial
"The reported price is a weighted average price. These shares were sold"
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.
indirectly beneficially own financial
"may be deemed to indirectly beneficially own the securities of the Issuer"
pecuniary interest financial
"disclaims beneficial ownership of such securities except to the extent of his pecuniary interest"
