Non-controlling interest is the portion of a subsidiary's equity not owned by the parent company but still shown in consolidated statements.
Non-Controlling Interest (NCI) is a term used under International Financial Reporting Standards (IFRS) to describe the ownership stake in a subsidiary company that is not owned by the parent company. This term is often synonymous with “minority interest” and plays a crucial role in consolidated financial statements.
Non-controlling interest can be classified based on the following criteria:
The NCI is typically calculated as a percentage of the subsidiary’s net income and net assets that are attributable to minority shareholders. Here is a basic formula:
In consolidated financial statements, non-controlling interests are presented within equity but separate from the parent shareholders’ equity. This distinction provides clear insight into the ownership structure of the subsidiary.
Assume Company A owns 70% of Subsidiary B. Subsidiary B reported a net income of $100,000 and paid dividends of $20,000. The non-controlling interest (NCI) would be calculated as follows:
