3 terms

weighted average financial

"Represents the weighted average of a range of sale prices from $84.32"

A weighted average is a way of calculating an overall number when some items matter more than others by giving each item a different level of importance, or weight. Investors use weighted averages to combine figures like prices, returns or earnings so the result reflects the size or significance of each part — like grading a class where a final exam counts more than a quiz, producing a score that better represents true performance.

non-derivative financial

"transaction_type": "non-derivative""

Rule 10b5-1 regulatory

"Footnotes may reference Rule 10b5-1 trading plans or pre-arranged"

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.
