BC37 In its deliberations in the second phase of the business combinations project, the US Financial Accounting Standards Board (FASB) decided to require entities with one or more partially‑owned subsidiaries to disclose in the notes to the consolidated financial statements a schedule showing the effects on the controlling interest's equity of changes in a parent's ownership interest in a subsidiary that do not result in a loss of control.

BC38 In the exposure draft proposing amendments to IAS 27 published in 2005, the Board did not propose to require this disclosure. The Board noted that IFRSs require this information to be provided in the statement of changes in equity or in the notes to the financial statements. This is because IAS 1 requires an entity to present, within the statement of changes in equity, a reconciliation between the carrying amount of each component of equity at the beginning and end of the period, disclosing separately each change. [When it issued IFRS 18, the IASB carried over these requirements in IAS 1 to IFRS 18.]

BC39 Many respondents to the 2005 exposure draft requested more prominent disclosure of the effects of transactions with non‑controlling interests on the equity of the owners of the parent. Therefore, the Board decided to converge with the FASB's disclosure requirement and to require that if a parent has equity transactions with non‑controlling interests, it should disclose in a separate schedule the effects of those transactions on the equity of the owners of the parent.
