sell-to-cover arrangements financial
"non-discretionary, sell-to-cover arrangements mandated by the issuer to fund tax withholding obligations"
restricted stock units financial
"Includes 1,038,662 restricted stock units, each of which represents a contingent right"
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.
non-discretionary financial
"This transaction was effected pursuant to non-discretionary, sell-to-cover arrangements mandated by the issuer"
average execution price financial
"The price reported in Column 4 is an average execution price"
revocable trust financial
"These securities are held directly by the KANG & CECILLIA SUN FAMILY 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.
