What it means
A company with several businesses is hard to judge from one profit figure. A strong division can hide a weak one, so the combined result may look fine while one part loses money.
Segment reporting separates the parts so that investors and managers can see which drive the results. Under accounting standards, segments are defined by how management itself runs and reviews the business.
If the chief decision maker looks at results by region, then regions are the segments. This management approach means the disclosures match what the leaders actually use.
A segment must be reported separately if it passes size tests, commonly that it makes up at least 10% of total revenue, profit or assets. Segments below the line can be grouped together, but the reported segments must usually cover a large majority of the total.
The exact tests are set by the standards and should be confirmed for each framework. Reported items typically include revenue, a profit measure, assets and sometimes depreciation, interest and capital spending.
The company must also reconcile the segment totals to the figures in the main financial statements. That reconciliation shows how head-office costs and other items fit in.
For internal use, segment reports guide decisions on where to invest, cut or sell. Non-finance managers should be careful about how shared costs are allocated, since a different allocation can change which segment appears most profitable.
Segment data is useful well beyond the annual report. Analysts use it to value each business separately, a method sometimes called sum-of-the-parts, and managers use it to set targets and bonuses.
Because so many decisions rest on it, the allocation rules should be written down and applied consistently from year to year.
In practice
Real-world examples
Example 1
A conglomerate has a food division, a packaging division and a logistics arm. Its annual report shows revenue and profit for each. An analyst notes that logistics is growing quickly while packaging is flat, and uses the split to value each part of the group separately.
Example 2
A software company reports its results by region: North America, Europe and Asia. The regional breakdown reveals that Europe has the highest margin. Management decides to put new sales hires there. Without the split, the stronger margin would have been averaged away.
Example 3
A retailer with stores and an online arm tracks them as separate segments. The online arm shows rising sales but thinner profit after delivery costs. The board debates whether to change its shipping policy. The online arm would look healthier on a combined basis, which is why the split matters.
Think of it
Imagine a large shopping mall. Looking at total daily visitors is like looking at a company's total revenue. Segment reporting is like checking the individual footfall counter for each specific shop, telling you whether the bookshop is booming or the shoe shop is empty.
Formula
Calculation
Segment share of revenue = segment revenue / total revenue x 100
Suppose a company has total revenue of $50,000,000 split into four divisions. Division A earns $22,000,000, which is 22,000,000 / 50,000,000 = 44%. Division B earns $18,000,000, or 36%, Division C earns $7,000,000, or 14%, and Division D earns $3,000,000, or 6%. The 10% threshold is $5,000,000, so Divisions A, B and C are reported, and together they cover $22,000,000 + $18,000,000 + $7,000,000 = $47,000,000, which is 94% of revenue.Case study
Seen in the real world
Redfern Holdings is an illustrative, fictional group with a hotel business and a catering business. Its consolidated profit was a steady $6,000,000, so investors assumed both parts were healthy.
When the company started reporting segments, the hotels earned $8,000,000 and the catering arm lost $2,000,000. The catering losses had been hidden by the larger hotel profits for years.
Faced with the new disclosure, the board restructured the catering business and sold a weak contract. The illustrative lesson is that a combined figure can mask problems that segment data brings into the open. Investors also began to ask sharper questions about capital spending in each part of the group. Management responded by publishing clearer targets for each division, which made the group easier to follow.
Watch out
Common mistakes
- Assuming segments must match the legal entities or the organisation chart, when they follow how management reviews performance and allocates resources.
- Comparing segment profits without checking how shared costs such as head-office salaries, rent and technology have been allocated.
- Ignoring the reconciliation to the main statements, which explains the gap between segment totals and group results.
Questions
People also ask
Who has to report segments?
Mostly companies with publicly traded shares or debt, though private companies often produce internal segment reports for management and for lenders who want to see where profit is earned.
How many segments should a company have?
There is no fixed number, but too many can become hard to manage, and standards suggest considering a practical limit around ten.
What is the difference between segment and geographic reporting?
Geographic information is an additional disclosure of results by country or region, while segments follow the management structure. A company can have both, and the two can overlap.
