Key Terms

3 terms

Form 144 regulatory

"144: Securities Sold During The Past 3 Months"

Form 144 is a document that investors must file with the government when they plan to sell a large number of shares of a company's stock. It helps ensure transparency so everyone knows how many shares are being sold and when, which can impact the stock's price.

Deferred Compensation financial

"Common | 06/01/2026 | Deferred Compensation"

Deferred compensation is pay that employees or executives have earned now but will receive at a later date, such as delayed bonuses, retirement benefits, or stock grants. It matters to investors because it creates future obligations and shapes incentives—like a promise to pay later that can affect a company’s reported profits, cash needs and potential stock dilution—so it helps signal how a business manages costs and retains key people.
