Rule 10b5-1 trading plan regulatory
"The exercise and/or sale of shares was effected pursuant to a Rule 10b5-1 trading plan entered into by the reporting person on March 11, 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 price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $166.83 to $167.64, inclusive."
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.
501(c) Foundation financial
"These shares are held by a 501(c) Foundation for which the reporting person and his spouse serve as co-trustee."
Annuity Trusts financial
"Reporting person is the trustee of the Kenneth Duda Annuity Trusts."
co-trustee financial
"These shares are held in a trust for the benefit of a Child of the reporting person for which the reporting person serves as co-trustee."
disclaims beneficial ownership regulatory
"The reporting person shares voting and investment control over the shares but disclaims beneficial ownership of the shares."
