Final answer:
A proxy is the document that allows a shareholder to authorize someone else to vote on their behalf in case of absence.
Step-by-step explanation:
A written document in which a shareholder authorizes another person to vote the shareholder's shares at the shareholders' meetings in the event of the shareholder's absence is known as a proxy. This arrangement allows shareholders to maintain their voting rights even when they cannot attend meetings in person. The individual granted the proxy then votes on corporation matters on behalf of the absent shareholder, according to the instructions provided by the shareholder.
