5 terms
Rule 10b5-1 trading plan regulatory
"This sale reported on this Form 4 was effected pursuant to a Rule 10b5-1 trading plan"
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 reported price 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.
exercise price financial
"1/4 of the shares subject to the option vested on August 20, 2019"
The exercise price is the fixed amount at which you can buy or sell an asset, like a stock, when using an options contract. It matters because it helps determine whether exercising the option will be profitable or not, depending on the current market price. Think of it as the set price you agree on today to buy or sell later.
convertible financial
"Each share of Class B Common Stock will also be convertible at any time"
A convertible is a type of investment that starts as a loan or preferred stake (like a bond or preferred share) but can be exchanged for common shares of the company at a set price or under certain conditions. It matters to investors because it offers a mix of steady income and downside protection like a loan, plus the upside of stock ownership if the company does well—similar to holding a coupon that you can trade for a full ticket if the event becomes valuable.
tax liability financial
"Payment of exercise price or tax liability by delivering or withholding securities"
