DRIP acquisition financial

"DRIP acquisition exempt from Section 16 reporting being reported voluntarily"

Section 16 regulatory

"DRIP acquisition exempt from Section 16 reporting being reported voluntarily"

Section 16 is a U.S. securities law rule that governs the trading and disclosure obligations of company insiders — typically officers, directors and large shareholders — to promote transparency and deter unfair profit-taking. It requires insiders to publicly report their stock trades and allows companies or the issuer to reclaim quick, short-term profits from certain insider trades, like a scoreboard and a refund policy that help investors see and limit possible insider advantage.

vesting financial

"500 shares vest on 11/15/2019, 11/15/2020, 11/15/2021 and 11/15/2022"

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.
