Key Terms

10b5-1 plan, weighted average sales price, vesting commencement date

3 terms

10b5-1 plan regulatory

"effected pursuant to a 10b5-1 plan"

A 10b5-1 plan is a pre-arranged strategy that allows company insiders to buy or sell their shares at predetermined times and prices, even while they are aware of confidential information. It acts like a scheduled appointment for trading, helping ensure transactions happen transparently and legally, which can reassure investors that trades are not based on insider knowledge.

weighted average sales price financial

"reflects a weighted average sales price"

vesting commencement date technical

"The vesting commencement date is April 1, 2023."

The vesting commencement date is the starting point when an employee begins earning ownership rights to their promised benefits, such as stock options or retirement contributions. Think of it like the day a savings account is opened—only after this date do the benefits start to grow and become fully available over time. It matters to investors because it marks when the clock begins ticking toward full ownership, affecting the timing and value of these benefits.
