4 terms

weighted average purchase price financial

"The price reported ... reflects the weighted average purchase price."

The weighted average purchase price is the average cost per share you paid across multiple buys, calculated so larger purchases count more than smaller ones. Imagine buying apples at different prices: the overall price you effectively paid depends on how many apples you bought at each price. Investors use it to measure true cost basis, calculate gains or losses, decide when to sell, and manage taxes and portfolio performance.

indirect ownership financial

"These securities are directly held by The Landesberg Living Trust..."

open market or private transaction financial

"Purchase in open market or private transaction"

Rule 10b5-1 trading plan regulatory

"No Rule 10b5-1 trading plan is associated with the reported transaction"

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.
