4 terms
Rule 10b5-1 trading plan financial
"Transaction made pursuant to a Rule 10b5-1 trading plan adopted on 11/19/2025"
A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.
indirect ownership financial
"Ownership type reported as indirect through various family trusts and accounts"
irrevocable trust financial
"Common Stock held in The Joseph Roger Sciammas 2020 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.
GRATs financial
"Indirect holdings reported as Various Sciammas GRATs with 11062.0000 shares"
