weighted average price financial

"The price reported in Column 4 is a weighted average price, rounded to the nearest cent."

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.

Restricted Stock Units financial

"Includes 12,516 Restricted Stock Units credited to the Reporting Person's account under the Issuer's 2009 Incentive Stock and Awards Plan, as amended and restated."

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

Incentive Stock and Awards Plan financial

"credited to the Reporting Person's account under the Issuer's 2009 Incentive Stock and Awards Plan, as amended and restated."

open-market purchase financial

"transaction_action": "open-market purchase""

An open-market purchase is when an investor or a company buys shares on a public stock exchange at the going market price, rather than through a private deal. It matters to investors because these purchases change how many shares are available, can push the stock price up or signal confidence from large buyers, and often affect per-share metrics like earnings—think of it like someone buying lots of apples off a grocery shelf, reducing supply and potentially raising the price.
