Financial instruments are assets or contracts that hold monetary value and can be bought, sold, or traded. They serve as tools for investors to grow, protect, or transfer money, much like how a ticket or voucher can be used to access goods or services. These instruments help individuals and organizations manage financial goals and risks across different markets and economic conditions.

proxy voting financial

"10. In case of proxy voting Name of the proxy holder"

Proxy voting is a process that allows investors to have their voting power on company decisions exercised by someone else if they cannot attend meetings in person. It ensures that their opinions are still represented, similar to authorizing someone else to vote on their behalf at an election. This helps investors influence company actions even when they cannot be physically present.
