What constitutes significant influence under IAS 28.6?
U
IAS 28 Significant — Core Rule
Under IAS 28 Significant Influence — 20% Rule, an investor that holds 20% or more of the voting power of an investee is presumed to have significant influence over that entity, unless it can be clearly demonstrated otherwise, requiring accounting for the investment using the equity method (IAS 28.5–28.6).
How IAS 28 Significant Works
The 20% threshold is a rebuttable presumption, not a bright line. Holding ≥20% of voting rights creates a presumption of significant influence; holding <20% creates the reverse presumption — that no significant influence exists. Both presumptions can be rebutted by evidence (IAS 28.6).
Qualitative indicators supplement the voting-power test. Even below 20%, significant influence may be evidenced by: representation on the board of directors; participation in policy-making processes; material transactions between investor and investee; interchange of managerial personnel; or provision of essential technical information (IAS 28.6(a)–(e)).
Potential voting rights must be considered. Currently exercisable or convertible instruments (options, warrants, convertible debt) that would give additional voting rights are factored into the significant-influence assessment, even if not yet exercised (IAS 28.7–28.8).
