How long is a proxy valid?

The validity period of a proxy is designed to ensure that the proxy reflects the most current intentions of the shareholder. A proxy is typically valid for a period of 11 months from the date of execution, in line with corporate governance rules that allow shareholders to delegate their voting rights temporarily. This timeframe helps maintain shareholder engagement and ensures that the proxy does not extend indefinitely without fresh consent from the shareholder.

While a proxy can indeed be revoked by the shareholder at any time prior to its exercise, this does not extend its validity beyond the 11-month period established in the general corporate framework. Thus, the correct answer reflects this regulatory structure.
