Brazilian Depository Receipts financial

"The shares were acquired through the exchange of Brazilian Depositary Receipts"

Brazilian Depositary Receipts are financial certificates issued in Brazil that represent ownership of shares in companies listed outside Brazil, allowing local investors to buy and sell foreign stocks without using a foreign exchange. They matter because they let investors easily access international companies while trading in local currency and under domestic rules, exposing portfolios to foreign business performance and currency moves much like buying a locally labeled version of a foreign product.

weighted average price financial

"The price reported is a weighted average price. These BDRs were sold"

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.

pecuniary interest financial

"disclaims beneficial ownership ... except to the extent of its pecuniary interest"
