restricted stock units ("RSUs") financial
"shares sold by the Reporting Person to cover tax withholding obligations in connection with the vesting and settlement of restricted stock units ("RSUs")."
Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.
sell to cover financial
"The sales were to satisfy tax withholding obligations to be funded by a "sell to cover" transaction."
Sell to cover is when a person who receives company stock through options or awards sells just enough shares immediately to pay required taxes, exercise costs, or fees, keeping the rest. Think of it like cashing part of a bonus to cover the tax bill so you can keep the remainder. For investors, it can create predictable small selling pressure and slightly change the number of shares actually held by insiders without increasing long‑term dilution.
weighted average price financial
"The price reported in this line item 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.
block trades financial
"These shares were sold as part of block trades for multiple security holders of the Issuer"
A block trade is a single, large buy or sell of shares or bonds arranged privately between big traders rather than piecemeal on the public market. Think of it like buying a whole shipment at once instead of many small shopping trips; it lets large holders move big positions with less immediate disruption but can signal strong buying or selling pressure and cause price swings once the trade is known, so investors watch block trades for clues about market sentiment and liquidity.
vesting date financial
"subject to the Reporting Person's provision of service to the Issuer on each vesting date."
