restricted stock units (RSUs) financial
"These securities are restricted stock units (RSUs). Each RSU represents"
Restricted stock units (RSUs) are a type of company promise to give employees shares of stock in the future, usually after certain conditions like working for a set time. They are like a gift promised today that you receive later, which can become valuable if the company's stock price goes up. RSUs matter because they are a way companies reward employees and can be a significant part of compensation.
Outside Director Compensation Policy financial
"The RSUs are awarded in connection with the Company's Outside Director Compensation Policy"
irrevocable trust financial
"These shares are held by the David M. DiDomenico 2012 Irrevocable Trust"
An irrevocable trust is a legal arrangement where an owner transfers assets into a separate entity managed by a trustee and gives up the power to modify or reclaim those assets. For investors it matters because putting stock or other holdings into such a trust can change who controls and benefits from the assets, affect taxes and creditor protection, and influence how easy it is to sell or value those holdings—like placing valuables in a locked safe overseen by someone else.
