Brazilian Depositary Receipts financial
"Brazilian Depositary Receipts ("BDR") are certificates representing Common Shares, no par value"
Brazilian Depositary Receipts (BDRs) are certificates traded on Brazilian exchanges that represent ownership of shares in foreign companies, allowing local investors to buy and sell exposure to those overseas stocks without opening foreign brokerage accounts. They matter because they let investors diversify across global companies using local currency and trading hours, similar to buying a locally issued voucher for a foreign product, while still exposing portfolios to the performance and risks of the underlying foreign shares.
Securities Lending Agreement financial
"Certain clients managed by Kapitalo entered into securities lending agreements whereby title to the securities"
beneficial ownership financial
"such clients may be deemed to continues to have beneficial ownership over the securities reported herein"
Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.
indirectly beneficially owned financial
"may be deemed to be indirectly beneficially owned by Bruno Sousa Mauad, a partner of Kapitalo"
