Goodwill in acquisitions: what it is, how it is measured and why it is impaired

Goodwill is what a buyer pays for a business beyond its identifiable net assets. How it is calculated, what it represents, how impairment testing works and what write-downs tell you.

When one company buys another, it rarely pays exactly the value of the assets it can list and measure. Usually it pays more. The extra amount reflects things that make the business worth more than the sum of its identifiable parts: an assembled, experienced workforce; established ways of operating; the expected benefits of combining the businesses; and the earning power of a going concern.

In the accounts, that extra amount is recorded as goodwill. Goodwill can be one of the largest assets on the balance sheet of an acquisitive company, and large write-downs of goodwill are among the clearest signals that an acquisition has disappointed.

This article explains what goodwill is, how it is calculated using what the source course material calls the goodwill equation, what it does and does not include, how it is tested for impairment under Australian standards, how US treatment differs, and what goodwill means for buyers, sellers and readers of financial statements. It is part of GoCore’s series on investments, groups and acquisitions.

What goodwill is

Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognised.

In plainer terms, goodwill is what is left over after everything that can be identified and measured has been. It typically reflects:

  • the value of the acquired business as a going concern, beyond its individual assets
  • an assembled workforce, which is not recognised as a separate asset
  • expected synergies: cost savings, revenue gains or other benefits from combining the businesses
  • other benefits that cannot be separately identified, such as market position not captured in specific intangible assets

It can also reflect overpayment. If a buyer pays too much, the excess still appears as goodwill at first, and is later exposed through impairment.

As the course material notes, goodwill is recognised only in a business combination. It never arises in an asset acquisition, as explained in Asset acquisition or business combination.

What goodwill is not

Before goodwill is calculated, the acquirer must identify and measure all identifiable assets and liabilities at fair value, including intangible assets that the acquired business never recorded. An intangible asset is identifiable if it can be separated and sold, licensed or transferred, or if it arises from contractual or legal rights. Examples include:

  • customer contracts and customer relationships
  • brand names and trademarks
  • patents, software and technology
  • licences and permits
  • order backlogs
  • non-compete agreements

These are recognised separately, not included in goodwill. This matters because most identifiable intangibles with finite lives are amortised, reducing profit over time, whereas goodwill is not amortised under Australian standards.

The goodwill equation

The calculation, which the source course introduces as the goodwill equation, is:

Goodwill = Consideration transferred + Non-controlling interest + Fair value of any previously held interest − Fair value of identifiable net assets acquired

Where:

  • consideration transferred is the fair value of what the acquirer gives: cash, shares, other assets and the fair value of any contingent consideration
  • non-controlling interest is the share of the acquired business owned by others, if the acquirer buys less than 100%
  • previously held interest is the fair value of any stake the acquirer already held before gaining control
  • identifiable net assets are the fair values of identifiable assets less liabilities

Worked examples

These are illustrations with round numbers.

Example 1: buying 100%

A company buys all the shares of another for $2,000,000 cash. The acquired company’s identifiable assets and liabilities at fair value are:

ItemFair value
Property, plant and equipment$900,000
Inventory and receivables$500,000
Customer relationships$300,000
Brand name$200,000
Liabilities−$400,000
Identifiable net assets$1,500,000

Goodwill = $2,000,000 − $1,500,000 = $500,000.

Note that customer relationships and the brand ($500,000 together) are recognised separately. Without identifying them, goodwill would have appeared to be $1,000,000.

Example 2: buying 75%

Now suppose the buyer pays $1,500,000 for 75% of the same company.

Under Australian standards, the non-controlling interest can be measured in one of two ways, chosen for each acquisition:

  • Proportionate share of identifiable net assets: 25% × $1,500,000 = $375,000. Goodwill = $1,500,000 + $375,000 − $1,500,000 = $375,000, representing the acquirer’s share of goodwill only.
  • Fair value: suppose the 25% non-controlling interest is valued at $460,000. Goodwill = $1,500,000 + $460,000 − $1,500,000 = $460,000, sometimes called “full goodwill”, covering the whole business.

US standards require non-controlling interests to be measured at fair value.

Example 3: a bargain purchase

Occasionally the fair value of identifiable net assets exceeds the consideration, for example in a forced sale. Before recognising a gain, the acquirer must reassess whether it has correctly identified and measured all assets and liabilities and the consideration. If an excess remains, it is recognised as a bargain purchase gain in profit. Such gains are uncommon, and large ones attract scrutiny.

Earn-outs in the equation

When part of the price depends on future performance, through an earn-out or other contingent consideration, its fair value at the acquisition date is included in the consideration transferred, and therefore affects goodwill. Later changes in the fair value of contingent consideration classified as a liability generally go to profit, not to goodwill. The goodwill figure is set at acquisition; subsequent movements in the earn-out do not change it.

This means a buyer’s estimate of the likely earn-out at the acquisition date matters. An optimistic estimate increases both the earn-out liability and goodwill; if the business then underperforms, the liability falls with a gain in profit, while goodwill may need to be impaired.

Goodwill in associates and joint ventures

Goodwill can also arise when an investor buys a significant but non-controlling stake in an associate or joint venture and pays more than its share of the investee’s identifiable net assets at fair value. In that case, the goodwill is not shown separately. It is included in the carrying amount of the investment under the equity method, and the investment as a whole is tested for impairment when there are signs of a decline in value. The article The equity method explained describes this.

What acquirers must disclose

Australian standards require acquirers to disclose information about each material business combination, including a description of the acquired business and the reasons for the acquisition, the consideration and its components, the amounts recognised for each major class of assets and liabilities, a qualitative description of the factors that make up goodwill, such as expected synergies or an assembled workforce, and the acquired business’s contribution to revenue and profit. These disclosures help readers judge what was bought, why, and whether the price looks reasonable.

Provisional amounts and the measurement period

Measuring the fair values of every asset and liability takes time, and acquisitions often happen near reporting dates. Standards allow a measurement period of up to one year from the acquisition date. During that period, provisional amounts can be adjusted, with a corresponding adjustment to goodwill, if new information is obtained about facts and circumstances that existed at the acquisition date.

After acquisition: impairment testing

Under Australian standards (AASB 136 Impairment of Assets), goodwill is not amortised. Instead:

  • goodwill is allocated to the cash-generating units, or groups of units, expected to benefit from the acquisition; a cash-generating unit is the smallest group of assets that generates largely independent cash inflows
  • each unit, or group of units, containing goodwill is tested for impairment at least annually, and whenever there is an indication of impairment
  • the unit’s recoverable amount, the higher of its fair value less costs of disposal and its value in use (the present value of expected future cash flows), is compared with its carrying amount
  • if the carrying amount is higher, an impairment loss is recognised, reducing goodwill first and then other assets of the unit
  • impairment losses on goodwill are never reversed, even if conditions later improve

Why goodwill gets impaired

Common causes of goodwill impairment include:

  • the acquired business underperforming its forecasts
  • expected synergies failing to materialise
  • adverse changes in the market, technology or regulation
  • higher interest rates, which reduce the present value of future cash flows
  • overpayment at the time of acquisition, especially during booms

GoCore’s article The assets the balance sheet cannot see observes that repeated large impairments often suggest a management team that overpays for acquisitions.

How US treatment differs

Under US standards, goodwill is also generally not amortised for public companies; it is tested for impairment at least annually by comparing the fair value of a reporting unit with its carrying amount. Private companies, however, may elect an accounting alternative to amortise goodwill, generally over ten years or less, with simplified impairment testing. This is one of the more significant differences between the two frameworks for smaller entities.

Goodwill in small business sales

In Australian small business sales, the word “goodwill” is often used more loosely, to describe the part of the price above the value of equipment and stock. That everyday usage overlaps with, but is not the same as, accounting goodwill. In a formal business combination, many items that a small business seller would call goodwill, such as customer relationships, a trading name or a lease, may be recognised as separate identifiable intangible assets, with only the remainder recorded as goodwill.

Tax is different again. For Australian tax purposes, goodwill is generally a capital gains tax asset rather than a depreciable asset, and its tax treatment depends on the structure of the sale. Buyers and sellers should obtain tax advice specific to their transaction.

Keeping it proportionate for smaller acquisitions

For a small business making a modest acquisition, the full process of identifying, valuing and testing intangible assets and goodwill can seem heavy. The effort should be proportionate to the size of the acquisition and to who relies on the financial statements. An entity preparing financial statements under Australian Accounting Standards must still follow the requirements, but for small acquisitions the valuation work can often be simpler, provided the key judgements are reasonable and documented. Where financial statements are not required to comply with accounting standards, such as some management or special-purpose reports, the treatment may differ, and the basis used should be made clear to readers.

Reading goodwill in financial statements

For investors and lenders, goodwill deserves careful attention:

  • Size relative to equity. If goodwill is a large share of a company’s equity, its net tangible assets may be small or negative.
  • Impairment history. Repeated impairments suggest overpayment or poor integration.
  • Assumptions in impairment testing. Disclosures show the growth rates and discount rates used; optimistic assumptions can delay impairments.
  • Headroom. Some companies disclose how much recoverable amount exceeds carrying amount; small headroom means a modest change could trigger an impairment.
  • Underlying performance. Goodwill is only as valuable as the earnings of the business it relates to.

What goodwill means for buyers

For a business considering an acquisition:

  • Identify intangibles carefully. Customer relationships, brands and technology must be valued separately; this affects future amortisation and goodwill.
  • Be realistic about synergies. Paying for synergies that do not arrive leads to impairment.
  • Expect scrutiny. Large goodwill balances attract attention from auditors, lenders and investors.
  • Plan for impairment testing. Annual testing requires forecasts, discount rates and documentation.

Common mistakes

Treating goodwill as a catch-all. Identifiable intangibles must be recognised separately first.

Assuming goodwill is amortised. Under Australian standards it is tested for impairment instead.

Ignoring non-controlling interest choices. Proportionate and fair value measurement produce different goodwill.

Overlooking the measurement period. Provisional amounts can change within a year.

Confusing accounting goodwill with small business sale goodwill or tax goodwill. Each has its own meaning.

Questions to ask

  • What identifiable intangible assets were acquired, and how were they valued?
  • What does the remaining goodwill represent: synergies, workforce, going-concern value or overpayment?
  • How is goodwill allocated to cash-generating units, and how much headroom exists?
  • Has the company recorded goodwill impairments before, and why?
  • For your own business: if you bought a business, how much of the price would be supported by identifiable assets?

Bringing it together

Goodwill is the excess of what a buyer pays for a business, plus any non-controlling interest and previously held interest, over the fair value of identifiable net assets. It represents going-concern value, an assembled workforce, synergies and other unidentifiable benefits, and sometimes overpayment. It arises only in business combinations, after identifiable intangibles have been recognised separately.

Under Australian standards, goodwill is not amortised but is tested for impairment at least annually, and impairments are never reversed. Understanding how goodwill is measured and tested helps buyers price acquisitions realistically and helps readers judge whether past acquisitions have created value.
