Cash Generating Unit (CGU)

Definition

The smallest identifiable group of assets that generates cash inflows largely independent of the cash inflows from other assets or groups of assets. Under IAS 36, when an individual asset's recoverable amount cannot be estimated in isolation, impairment testing is performed at the CGU level. Goodwill acquired in a business combination is allocated to CGUs or groups of CGUs expected to benefit from the synergies of the combination, and tested for impairment at that level annually.

Complementary Terms

Concepts that frequently appear alongside Cash Generating Unit (CGU) in practice.

Reporting Unit

The level at which goodwill is tested for impairment under US GAAP (ASC 350), defined as an operating segment or one level below an operating segment (a component). A component is a reporting unit if it constitutes a business for which discrete financial information is available and segment management regularly reviews its operating results.

Goodwill Impairment Testing

The mandatory annual assessment (and more frequent assessment when indicators exist) of whether the carrying amount of goodwill exceeds its recoverable amount. Under IAS 36, goodwill is tested at the cash generating unit level by comparing the unit's carrying amount (including allocated goodwill) with its recoverable amount.

Free Cash Flow (FCF)

The cash a company generates from operations after deducting capital expenditures. FCF represents the cash available to pay dividends, reduce debt, or reinvest in the business, and is a key input in discounted cash flow valuations.

Unit Economics

The direct revenues and costs associated with a single unit of a business model—typically one customer, one transaction, or one product sold. Healthy unit economics (where lifetime value exceeds acquisition cost with adequate margin) are a prerequisite for sustainable growth at scale.

Normalised Cash Flow

Cash flow adjusted to remove non-recurring, extraordinary, or owner-specific items to reflect the sustainable earnings capacity of a business under normal operating conditions. Normalisation adjustments commonly include removing one-time restructuring charges, above-market owner compensation, related-party transactions, and non-operating income.

Discounted Cash Flow (DCF)

A valuation method that estimates the present value of a company based on projections of its future free cash flows, discounted back to today at the cost of capital. DCF valuations are sensitive to growth assumptions and are often used alongside multiples-based approaches.

Goodwill Impairment

A non-cash charge recorded when the carrying value of goodwill on the balance sheet exceeds its estimated recoverable amount. Goodwill impairment testing, required annually under IFRS and US GAAP, often signals that the intangible value anticipated at the time of acquisition — including synergies, customer relationships, and growth potential — has not been realised.

Useful Life Assessment

The process of determining the period over which an intangible asset is expected to contribute to the cash flows of an entity, which governs the amortisation period under IAS 38 and ASC 350. Useful life may be finite (based on contractual, legal, regulatory, technological, or economic factors) or indefinite (when there is no foreseeable limit to the period over which the asset will generate net cash inflows).
