According to the International Accounting Standards, significant influence is the power to participate in the financial and operating policy decisions of the investee but is not control or joint control over those policies.
If an investor holds, directly or indirectly (e.g. through subsidiaries), 20 per cent or more of the voting power of the investee, it is presumed that the investor has significant influence, unless it can be clearly demonstrated that this is not the case. Conversely, if the investor holds, directly or indirectly (e.g. through subsidiaries), less than 20 per cent of the voting power of the investee, it is presumed that the investor does not have significant influence, unless such influence can be clearly demonstrated. A substantial or majority ownership by another investor does not necessarily preclude an investor from having significant influence.
The existence of significant influence by an investor is usually evidenced in one or more of the following ways:
(a) representation on the board of directors or equivalent governing body of the investee;
(b) participation in policy-making processes, including participation in decisions about dividends or other distributions;
(c) material transactions between the investor and the investee;
(d) interchange of managerial personnel; or
(e) provision of essential technical information.
