Grantor Trust financial
"Indirect ownership is reported as "By Grantor Trust" for certain shares."
A grantor trust is a legal arrangement where the person who puts assets into the trust keeps enough control or rights that, for tax and legal purposes, those assets are treated as still belonging to that person. For investors, that matters because income, gains and losses generated by the trust typically flow through to the grantor (or directly to investors) for tax reporting and distributions, affecting after-tax returns and cash flow predictability — think of it like a mailbox that forwards all the mail back to the sender rather than holding it inside.
average weighted price financial
"Price reported constitutes the average weighted price of shares sold."
Power of Attorney regulatory
"Remarks reference "Exhibit 24.1 - Power of Attorney" for the filer."
A power of attorney is a legal document that allows one person to make decisions and act on behalf of another person, often in financial or legal matters. It’s like giving someone a trusted helper or agent the authority to handle important tasks if you are unable to do so yourself. This matters to investors because it can impact how their assets are managed or transferred if they become unable to oversee their affairs.
