5 terms

ten percent owner regulatory

"The reporting person is marked as a ten percent owner of the issuer."

open market financial

"The shares were sold in the open market and the price reported is an average price."

An open market is a system where buying and selling of goods, services, or financial assets happen freely without restrictions or special controls. For investors, it means they can trade assets easily and quickly, which helps determine fair prices based on supply and demand. This environment encourages transparency and competition, making it easier to buy or sell with confidence.

weighted-average price financial

"The shares were sold in the open market and the price reported is an average price."

Weighted-average price is the average of multiple prices where each price is counted according to its size or importance—larger trades carry more weight than smaller ones, like averaging course grades by credit hours. It matters to investors because it gives a more realistic picture of the true price paid or received, helping assess trade execution, compare performance, calculate cost basis, and value positions more accurately than a simple average.

multiple transactions financial

"These shares were sold in multiple transactions at prices within the stated range."

Rule 10b5-1 regulatory

"The filing’s Rule 10b5-1 checkbox is not checked for these transactions."

Rule 10b5-1 is a regulation that allows company insiders to buy or sell their shares at predetermined times, even if they have access to non-public information. It acts like setting a schedule in advance for transactions, helping prevent accusations of unfair trading. This rule provides a way for insiders to plan trades transparently, giving investors confidence that these transactions are not based on hidden information.
