4 terms

Rule 10b5-1 trading plan financial

"This transaction was effected pursuant to a 10b5-1 trading plan adopted..."

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

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.

Employee Stock Purchase Plan financial

"Includes 16,626 shares purchased through Issuer's Employee Stock Purchase Plan..."

An employee stock purchase plan is a company program that lets workers buy shares through small payroll deductions, often at a discount to the market price and after a set offering period. Think of it like a workplace savings plan that turns into ownership: it encourages employees to share in the company’s success and can create predictable buying or selling of stock that investors watch because it affects supply, demand and employee incentives.

401(k) Plan financial

"and approximately 20,561 shares held through Issuer's 401(k) Plan."

A 401(k) plan is a workplace retirement account that lets employees set aside part of their pay into a tax-advantaged savings pot, often with employers adding matching contributions — like a workplace piggy bank for future income. It matters to investors because the amount people save and how employers fund these plans influence consumer spending, corporate payroll costs and the flow of money into financial markets, which can affect stock prices and company valuations.
