What it means
A large company often does very different things under one roof. A group may own a consumer products division, an industrial division and a financial services arm, each with its own profits and risks.
If the accounts showed only one combined number, investors could not tell which parts were doing well. Accounting standards, including US GAAP and IFRS, therefore require companies with publicly traded securities to report information about their operating segments.
They use what is called the management approach, which means the segments are defined the way the company's chief decision maker reviews the business internally. This keeps the external reports aligned with how managers actually run the company.
Not every segment has to be reported separately. A segment is generally reportable if it reaches 10% of combined revenue, 10% of combined profit or loss, or 10% of combined assets.
The reportable segments must also cover most of the company's external revenue, with a common benchmark being at least 75%. For each reportable segment the company discloses items such as revenue, profit measure, assets and sometimes depreciation.
It also reconciles the segment totals to the figures in the main financial statements. These disclosures help analysts compare divisions with competitors and spot weak areas that are hidden within the overall result.
Segment data can also be misleading if used carelessly. Managers have some freedom over how to group activities and allocate shared costs, so segment profits are not perfectly comparable between companies.
Reading the notes on how costs were allocated is a good habit. Segments matter outside the accounts too.
Lenders, boards and managers use segment results to decide where to invest, which divisions to fix and which to sell. A division that looks fine inside a large group may turn out to be a drag once it is shown separately.
In practice
Real-world examples.
Example
A technology company reports three segments: hardware, software and services. The notes show software has the highest profit margin at 35%, while hardware is at 12%. Investors use this to see that software drives most of the group's profit, even though hardware produces more of its sales.
Example
A food manufacturer reports results by region: North America, Europe and Asia. Asia has fast growth but low profit. The chief executive uses the segment data to decide where to invest next year, and asks the Asia team for a plan to raise its margin before adding capacity.
Example
A marketing manager at a bank divides retail customers into segments by age and income. She designs a different savings offer for each group. Although this is a marketing meaning of the word, it follows the same logic of treating distinct groups differently.
Formula
Calculation
Segment share of revenue = segment revenue / combined revenue of all segments x 100
A company has combined revenue of $200,000,000 across its segments. The Consumer segment earns $24,000,000, so its share is $24,000,000 / $200,000,000 = 0.12, which is 12%. This is above the 10% threshold, so Consumer must be reported separately. A small Services segment earns $15,000,000, a share of 7.5%, so on this test alone it need not be separate.Case study
Seen in the real world.
Ridgeway Holdings is a fictional group with a manufacturing division, a logistics division and a small software unit. Its annual report once showed only combined results, and analysts struggled to see why profit margins were falling.
After adopting segment reporting, the report revealed that logistics earned a margin of 4% while manufacturing earned 14%. This is an illustrative story, but the effect was real for the fictional board. They sold part of the logistics business and put the proceeds into manufacturing, and the group's overall margin improved.
The finance director, Anil, also added a note explaining how shared head office costs were allocated across divisions. This reduced questions from investors and made year-to-year comparisons easier.
Watch out
Common mistakes.
- Assuming every business unit must be reported as a segment. Only segments passing the quantitative tests or chosen by management are reported separately.
- Comparing segment profits across companies without checking cost allocations. Different methods of sharing head office costs can change the picture.
- Thinking segment reporting is only for large groups. It applies to public companies, though small private firms may use similar analysis for internal management.
Questions
People also ask.
What is segment reporting?
It is the disclosure of financial results for the distinct parts of a business, so users can see how each part performs.
What is the 10% test?
A segment is generally reportable if its revenue, profit or loss, or assets are at least 10% of the combined total for all segments.
Does the term also mean a customer group?
Yes, in marketing it describes a group of customers with shared traits, although the accounting meaning is about parts of the business.
