According to IFRS 10, what is one criterion that signifies control over an investee?

Control over an investee, as outlined in IFRS 10, requires an entity to have power over the investee. This criterion emphasizes that the power can be either exercised or not, indicating that control is not solely based on day-to-day operational involvement or ownership percentages. Power refers to the ability to direct the relevant activities of the investee, which significantly affects the investee's returns.

This concept is crucial because it acknowledges situations where an entity may control another entity through various arrangements or rights, even without majority ownership. For example, a minority shareholder may have special voting rights that allow them to influence key decisions, thereby establishing control that extends beyond mere equity stake percentages.

The other options provide insights into aspects of investment and ownership but do not capture the core principle of control specified in IFRS 10. Majority ownership suggests a strong position but does not inherently address the power dynamic unless aligned with the ability to direct relevant activities. Agreements among shareholders could inform operational decisions but do not automatically confer control unless they explicitly grant power. Likewise, direct involvement, while potentially indicative of control, does not guarantee it, as control can exist independently of such engagement.
