IFRS 8 Operating Segments: The Ultimate Guide for Financial Reporting

Key Takeaways

• The Goal: IFRS 8 forces public companies to reveal financial information by business segment, letting investors see the company “through the eyes of management.”
• The Scope: It strictly applies to publicly traded entities or companies in the process of going public.
• Reportable Status: An operating segment must be reported individually if it hits 10% or more of combined segment revenues, assets, or profits/losses.
• The 75% Floor: Individual reportable segments must account for at least 75% of the company’s total external revenue.

When you look at a massive multinational corporation, evaluating it based on a single net profit figure is virtually impossible.

IFRS 8 (Operating Segments) is the accounting standard that forces publicly traded companies to break down their financial performance by individual business units. This standard gives investors a clear look at a company “through the eyes of management,” revealing exactly which divisions are driving growth and which are losing money.

What is an Operating Segment?

Under IFRS 8, a business component isn’t just any internal department. To officially qualify as an operating segment, a unit must meet three strict criteria:

• Revenue & Expenses: It engages in active business operations that generate its own income and incur its own costs.
• Management Oversight: Its financial results are regularly reviewed by the Chief Operating Decision Maker (CODM)—typically the CEO or executive committee—to allocate resources and judge performance.
• Discrete Data: The company tracks specific, independent financial information for that unit.

What’s Excluded? Corporate headquarters, shared HR/IT departments, and company pension plans are not operating segments because they do not earn direct operational revenue.

The Rules of Aggregation

If a company has dozens of smaller units, listing them all would create unreadable financial statements. IFRS 8 allows companies to aggregate (group together) similar segments into a single reporting block, but only if they share highly similar economic characteristics, including:

• The nature of the products or services
• The type of production processes used
• The target class of customers
• The methods used to distribute goods or services

The 10% Threshold Tests (How Segments Are Chosen)

A segment doesn’t get its own dedicated section in an annual report just because it exists. It must be deemed a reportable segment by passing any one of these three quantitative tests:

The 75% External Revenue Safety Net

Even if a segment passes the 10% test, the calculation isn’t over. IFRS 8 features a strict core backstop to prevent companies from hiding major parts of their business:

At least 75% of the company’s total external revenue must be included in reportable segments.

The Rule in Action:
If the segments that passed the 10% tests only account for 60% of the company's external sales, management MUST manually add smaller segments to the report until they hit the 75% floor.

Any minor remaining segments that never make the cut are lumped together into a final catch-all line item labeled “All Other Segments.”

Frequently Asked Questions (FAQ)

a) What is the primary objective of IFRS 8?

The primary objective of IFRS 8 is to require an entity to disclose information that enables users of its financial statements to evaluate the nature and financial effects of the business activities in which it engages and the economic environments in which it operates. It achieves this by forcing companies to use the “management approach,” presenting data exactly how internal executives review it.

b) Who is the Chief Operating Decision Maker (CODM) under IFRS 8?

The Chief Operating Decision Maker (CODM) is not necessarily a single person with a specific title. Instead, it refers to a function within the entity responsible for allocating resources and assessing the performance of the operating segments. This function is frequently fulfilled by the Chief Executive Officer (CEO), the Chief Operating Officer (COO), or a management committee.

c) Is corporate headquarters an operating segment?

No, corporate headquarters and centralized departments (like shared IT or HR) are generally not operating segments. Under IFRS 8, an operating segment must engage in business activities from which it may earn revenues and incur expenses. Because corporate headquarters act as cost centers and do not generate direct operational revenue, they are excluded.

d) What is the difference between an operating segment and a reportable segment?

An operating segment is any internal component of a business that meets the three basic criteria (earns revenue, reviewed by the CODM, has discrete data). A reportable segment is a specific operating segment that is large enough to warrant individual disclosure in the public financial statements because it has passed at least one of the 10% quantitative thresholds or was added to satisfy the 75% external revenue rule.

Numerical Example: Navigating the 10% Profit or Loss Test

The Profit or Loss test is often the most confusing of the quantitative thresholds because it requires you to compare absolute values across profitable and loss-making segments. Let’s look at how it works in practice.

Case Study

Imagine GlobalCorp has 5 operating segments. At the end of the fiscal year, management records the following net segment results:

• Segment A: Profit of Rs 500,000
• Segment B: Profit of Rs 300,000
• Segment C: Loss of (Rs 600,000)
• Segment D: Loss of (Rs 400,000)
• Segment E: Profit of Rs 50,000

Step 1: Separate Profits from Losses

First, we separate the segments into two pools and sum their absolute totals.

• Profitable Segments (A, B, E): Rs 500,000 + Rs 300,000 + Rs 50,000 = Rs 850,000
• Loss-Making Segments (C, D): Rs 600,000 + Rs 400,000 = Rs1,000,000

Step 2: Identify the Benchmark

IFRS 8 states you must take the greater absolute amount between the two totals.

• Comparing Rs 850,000 (total profits) vs. Rs 1,000,000 (total absolute losses), the benchmark is Rs 1,000,000.

Step 3: Apply the 10% Threshold

Our threshold for a segment to be individually reportable under this test is 10% of our benchmark:

• 10% of Rs 1,000,000 = Rs 100,000

Step 4: Evaluate Each Segment (Absolute Value)

Any segment whose absolute profit or loss is Rs 100,000 or greater automatically becomes a reportable segment.

• Segment A (Rs 500,000): Greater than Rs 100,000, Reportable
• Segment B (Rs 300,000): Greater than Rs100,000, Reportable
• Segment C (│-Rs 600,000│ = Rs 600,000): Greater than ₹100,000, Reportable
• Segment D (│-Rs 400,000│ = Rs 400,000): Greater than ₹100,000, Reportable
• Segment E (Rs 50,000): Less than Rs100,000, Please remember it is Not Reportable under this test (Will be swept into “All Other Segments” unless it passes the asset/revenue tests or is needed for the 75% rule).
