What is the meaning of significant influence?

Significant influence is the power to participate in the financial and operating policy decisions of an economic entity but is not control or joint control over those polices

Significant influence can be determined by the  holding of voting rights in the entity. IAS Twenty eight states that if an investor holds twenty percent or more of the voting power of the investee, it can be presumed that the investor has significant influence over the investee, unless it can be clearly shown that this is not the case.
