"solely to satisfy certain tax withholding obligations in connection with the issuance of shares"

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.

non-discretionary basis financial

"automatically sold on a non-discretionary basis solely to satisfy certain tax withholding obligations"
