Latest developments

In March 2017, the IASB issued proposed amendments that follow on from a Post-implementation review (PIR) of IFRS 8 that was carried out to assess whether the standard works as intended. The PIR confirmed that the standard generally functions well but identified some areas that could benefit from improvements.

The proposed improvements in the exposure draft include amendments:

  • to clarify and emphasise the criteria that must be met before two operating segments may be aggregated;
  • to require companies to disclose the title and role of the person or group that performs the function of the chief operating decision maker; and
  • to require companies to provide information in the notes to the financial statements if segments in the financial statements differ from segments reported elsewhere in the annual report and in accompanying materials.

The Board has also proposed to amend IAS 34, 'Interim financial reporting', to require companies that change their segments to provide restated segment information for prior interim periods earlier than they currently do.

Comments are due 31 July 2017.


Segment guidance requires an entity to disclose information that enables users of the financial statements to evaluate the nature and financial effects of the business activities and the economic environments through the eyes of management ('management approach').

Though many entities manage their business using some level of ‘segmented’ data, the disclosure requirements are limited to (a) entities with listed or quoted equity or debt instruments and (b) entities that are in the process of obtaining a listing or quotation of debt or equity instruments in a public market. To the extent an entity not meeting either of these criteria chooses to disclose segmented data in financial statements, the information can only be referred to as ‘segment information’ if it complies with the segment guidance described below.

The identification of an entity’s operating segments is the core determinant for the level of information included in the segment disclosures. Operating segments are components of an entity, identified based on the breakout of information contained in the internal reports that are regularly used by the entity's chief operating decision-maker (CODM) to allocate resources and to assess performance.

Reportable segments are individual operating segments or a group of operating segments for which segment information must be separately reported (that is, disclosed). Aggregation of one or more operating segments into a single reportable segment is permitted (but not required) where certain conditions are met, the principal condition being that the operating segments should have similar economic characteristics (for example. profit margin, spreads, sales growth rates, etc.). Whether multiple operating segments can be aggregated into a single reportable segment is a matter of significant judgement.

For each segment disclosed, entities are required to provide a measure of profit or loss in the format viewed by the CODM, as well as a measure of assets and liabilities if such amounts are regularly provided to the CODM. Other segment disclosures include the revenue from customers for each group of similar products and services, revenue by geography and dependence on major customers. Additional detailed disclosures of performance and resources are required if the CODM reviews these amounts. A reconciliation of the total amount disclosed for all segments to the primary financial statements is required for revenue, profit and loss, and other material items reviewed by the CODM.
