4 terms

Rule 10b5-1 trading plan regulatory

"The sales reported were effected pursuant to the Rule 10b5-1 trading plan adopted by the reporting person on May 19, 2026."

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.

weighted average price financial

"The reported price in Column 4 is a weighted average price."

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.

revocable trust financial

"Shares held of record by Christopher K. Cox, Trustee of The Christopher K. Cox 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.

irrevocable remainder trust financial

"Shares held of record by Christopher K. Cox and Visra Vichit-Vadakan, Co-Trustees of The Cox-Vadakan Irrevocable Remainder Trust."
