Rule 10b5-1(c) trading plan regulatory

"under a pre-established Rule 10b5-1(c) trading plan"

A Rule 10b5-1(c) trading plan is a legally defined, pre-set schedule that lets company insiders automatically buy or sell stock at specified times or under set formulas when they are not in possession of undisclosed, sensitive information. Think of it like an automatic payment plan for trades: because the instructions are written in advance, trades under the plan help protect insiders from allegations of trading on secret information and give investors clearer expectations about when insiders will transact, which can affect liquidity and perceived transparency.

restricted stock units financial

"vesting of restricted stock units"

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.

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.
