Methodology

NSE Indices Ltd. classifies each company to basic industry whose definition most closely describes the nature of its business. As revenues are more stable than the profits, they are considered as basis to classifying a company into particular category of industry classification structure. Revenues provide more accurate description of company’s core business activities.

  • In case a company has only 1 line of business, company would be classified according to that business.
  • In case company has more than single business, classification is based on the business segment (Segment Revenue) that contributes more than 50% of the total revenue.
  • In case of a company engaged into multiple business segment, where no single business segment contributes more than 50% of companies' total revenue and two or more segments each contributes at least 20% of total revenue, such company would be classified as ‘Diversified’
  • In case of a company engaged into multiple business segment, where no single business segment contributes more than 50% of companies' total revenue and each business segments contribute less than 20% of total revenue, such company would also be classified as ‘Diversified’

Review of classification of companies:

The classification of all companies listed on NSE will be reviewed on annual basis following receipt of companies’ annual report. Additionally, classification of a company may be reviewed upon significant change in company's business activities as a result of any corporate event such as a merger or demerger.

If a company wishes to revise its current classification, it should contact NSE Indices Ltd. providing rationale for proposing a change of classification, having regard to the classification rules and attaching any documentary evidence in support of its claim.

No changes in classification will be made on the basis of non-public information, promises of action, assertions or company’s/ director’s aspiration, unless these can be substantiated by audited or independently authenticated formal company statements. Any adjustment resulting from a change in a company’s classification will be implemented at the same time as the corporate event is completed. A company's classification may also be reviewed by NSE Indices Ltd. either at their discretion or at the request of the company or professional advisors acting on its behalf.

Review of industry classification structure:

Changes to the industry structure is evolutionary. Any changes to the industry classification structure will be based on long-term trends and may not consider temporary fluctuations within individual industries. NSE Indices annually reviews the industry classification structure based on internal assessment, market feedback and consultation with relevant stakeholders.
