The rationale underlying the equity method is that an investor begins to gain the ability
to influence the decision-making process of an investee as the level of ownership rises.
According to FASB ASC Topic 323 on equity method investments, achieving this “ability
to exercise significant influence over operating and financial policies of an investee
even though the investor holds 50 percent or less of the voting stock” is the sole criterion
for requiring application of the equity method [FASB ASC (para. 323-10-15-3)].
