How Changes in Consolidation Scope Affect Revenue Growth
Learn to check subsidiary additions, disposals, and control assessments in annual reports. An acquisition example separates growth from newly consolidated revenue from growth in the existing business.
The consolidation scope in an annual report identifies which entities' assets, liabilities, and results are included in the consolidated financial statements. Acquisitions or disposals can change revenue and profit even if the existing business performs exactly as before. Before interpreting growth, check that the entities included and the periods of inclusion match between the current and prior periods.
Check control assessments as well as ownership percentages
Consolidation starts with control over another entity. Ownership percentage is an important clue, but cannot determine every case on its own. Read the company's disclosed reasoning, including voting rights structures and contracts, and establish whether the entity is a subsidiary or an associate. A company is not necessarily consolidated by the listed entity simply because it is described as an affiliate or belongs to the same group. Define which entities enter the listed company under analysis, and how they are accounted for, to avoid double-counting.
Check the date of inclusion and the period of earnings included
A company on the closing list of subsidiaries may not have contributed a full period's results. If control was acquired during the year, check the period included in profit or loss; the next year may show revenue growth simply because the comparative periods differ. Conversely, after a disposal and loss of control, revenue may leave the consolidation even if the same brand keeps operating. Record the names, dates, principal businesses, and disclosed revenue effects of additions and removals in a comparison table to explain changes in reported scale.
Assess reported and comparable-scope growth without mixing them
You may exclude acquired revenue to examine growth on a consistent business scope, but should not invent undisclosed amounts. A subsidiary's separate revenue does not necessarily equal the increase in consolidated revenue because intragroup eliminations and acquisition adjustments apply. If the company provides comparable figures, check their definitions and adjustments. Guarantees or other ownership-related risks may remain even after an entity leaves consolidation, so removal from the scope does not necessarily end every economic relationship.
Worked example
Hypothetical example: All amounts below are in units of KRW 100 million. Prior-year consolidated revenue is 1,000, and the existing business also generates 1,000 in the current year. A company acquired in July adds second-half revenue of 200, with no intragroup transactions or other adjustments, producing current-year consolidated revenue of 1,200 and growth of 20%. Existing-business growth is 0%. In the next year, if the acquired company contributes full-year revenue of 400 while the existing business is unchanged, total revenue of 1,400 grows by approximately 16.7% again. In this example, the increase comes from a longer period of inclusion, rather than growth in the businesses themselves.
What to check
- Check current-period additions and removals in the subsidiary list.
- Do not treat ownership percentage and control assessment as the same concept.
- Record the dates and number of months included in profit or loss.
- Keep reported growth separate from the basis for adjustments to a comparable-scope analysis.
