Segment reporting meaning in simple words: profit by business

The Plainomics desk2 sources

Segment reporting: a company breaking its revenue and profit into its main lines of business, so you can see which parts earn what.

Riya stands between the stall on one side and an office pantry on the other, pointing at both, while Sameer checks his phone.

The story

two people, one chai stall

An analyst emails asking how the office supply business is doing. Sameer forwards it to Riya.

Sameer

She wants office supply on its own. Don't we just report one big number?

Riya

No, we report by segment: each main line of business, the way you and the board track it.

Sameer

So, stalls and office supply.

Riya

Stalls brought in ₹100 crore of revenue and ₹12 crore of operating profit. Office and café supply brought in ₹20 crore and ₹2 crore.

Sameer

So supply is a sixth of our sales but only a seventh of our profit.

Riya

Exactly. Stalls make 12 paise on every rupee, supply makes 10. Without segments, nobody outside could see that.

Sameer

Could we hide a weak business by lumping it in with the stalls?

Riya

Not easily. Any line that's 10% or more of revenue, profit or assets usually has to stand on its own. Supply is about 17% of our sales, so it qualifies.

Sameer

And the analyst gets her answer.

Riya

Every quarter, in our results.

The grown-up version

same idea, exact words

Under Ind AS 108, an operating segment is a part of a company whose results are regularly reviewed by its chief operating decision maker to allocate resources and assess performance. A segment must be reported separately if its revenue, its profit or loss, or its assets are 10% or more of the combined figure for all segments, and further segments must be reported until they cover at least 75% of the company's external revenue. Listed companies with more than one reportable segment also publish segment information with their quarterly and annual results, in a format SEBI prescribes.

Formula

Segment margin = Segment result ÷ Segment revenue

Don't mix it up

the usual confusions

  • Segment reporting ≠ consolidated vs standalone

    That's about which companies are added together. Segments split the business by activity or region, whichever company it sits in.

  • Segment reporting ≠ subsidiary

    A segment isn't a separate company. One company can have several segments, and one segment can run across several companies.

  • Segment reporting ≠ segment result vs company profit

    Some costs, like head office, often aren't given to any segment. So segment results can add up to more than the company's operating profit.

Three quick sips

1/3 Stalls earn ₹12 crore on ₹100 crore of revenue. Supply earns ₹2 crore on ₹20 crore. Which has the higher margin?
