Restricted Stock Units financial
"Shares sold to satisfy tax obligations in connection with the vesting of previously granted Restricted Stock Units"
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
Revocable Trust financial
"Amounts reflect the shift from direct to indirect ownership of 52,603 shares contributed by Mr. Bergman to the Per Artur Bergman Revocable Trust"
A revocable trust is a legal arrangement where the person who creates it keeps control and can change or cancel the trust at any time, while naming who will manage and receive the assets later. Think of it like a flexible folder for your investments and property that can be relabeled or reworked as circumstances change; it matters to investors because it determines how ownership is recorded, how easily assets transfer on incapacity or death, and whether holdings bypass public probate proceedings.
Grantor Retained Annuity Trust financial
"The shares are held by The Per Artur Bergman Grantor Retained Annuity Trust No. 4"
A grantor retained annuity trust (GRAT) is an estate-planning tool where the person who creates the trust transfers assets into it but receives fixed cash payments (an annuity) from the trust for a set number of years; whatever remains after that term passes to designated beneficiaries. It matters to investors because it can shift future appreciation of assets out of the creator’s taxable estate—like putting an asset into a timed vending machine that pays you fixed amounts while any extra value that grows inside the machine goes to heirs with reduced gift or estate tax consequences.
investment advisor financial
"of which the reporting person is the investment advisor"
An investment advisor is a person or firm that provides personalized guidance on buying, selling and managing investments and often oversees client portfolios for a fee. For investors this matters because the advisor shapes risk, costs and long-term returns, and is typically required by law to act in the client’s best interests — think of them as a financial coach or GPS that helps navigate choices and avoid costly detours.
indirect ownership financial
"Amounts reflect the shift from direct to indirect ownership of 52,603 shares"
