weighted average price financial

"The price reported 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.

open-market or private transaction financial

"The transaction is described as a purchase in an open-market or private transaction."

indirect ownership financial

"Additional shares are reported as held indirectly through an IRA and MOM, LLC."

IRA financial

"Shares are reported as held indirectly by IRA."

An individual retirement account (IRA) is a savings account designed to help people put aside money for their retirement, often with tax advantages that encourage long-term savings. It matters to investors because it can grow over time, providing financial security later in life, and offers benefits that can reduce current taxes or allow investments to compound more effectively.

limited liability company financial

"An indirect holding is reported as held by MOM, LLC, a limited liability company."

A limited liability company (LLC) is a business structure that separates the owners’ personal assets from the company’s debts and legal obligations, like a protective shield that keeps personal savings and property distinct from business risk. For investors, that protection reduces personal financial exposure and often brings flexible rules for profit sharing and taxes, but it can also affect how easily interests are bought or sold and how decisions are made.
