Tax Amortisation Benefit (TAB)

The tax effect arising from temporary differences between the fair values assigned to assets and liabilities in a purchase price allocation and their corresponding tax bases. Under IAS 12 and ASC 740, deferred tax liabilities are recognised on the step-up in fair value of acquired intangible assets (which typically have zero tax basis), while deferred tax assets may arise on assumed liabilities.

A valuation methodology that estimates the value of an asset based on the present value of expected future economic benefits, such as cash flows, earnings, or cost savings. The income approach is the most widely used method for valuing intangible assets and includes techniques such as the relief-from-royalty and multi-period excess earnings methods.

A valuation technique used to isolate the value of a specific intangible asset by deducting the returns attributable to all other assets (tangible and intangible) from total earnings. The multi-period excess earnings method is the most common approach for valuing customer relationships and technology in purchase price allocations.

An element of M&A purchase price that is payable only if specified future conditions are met, such as revenue targets or product milestones. Contingent consideration must be measured at fair value at the acquisition date and is particularly common in deals where intangible asset values are uncertain.

The rate used to convert future expected cash flows into their present value, reflecting the time value of money and the risk associated with those cash flows. Selecting the appropriate discount rate is one of the most critical and sensitive decisions in intangible asset valuation, as small changes can materially alter the estimated fair value.

The average remaining period over which a group of intangible assets is expected to contribute to cash flows, weighted by their individual fair values. WARUL is used in purchase price allocation to determine amortisation periods for acquired intangible assets and is required disclosure under several accounting standards.

A portion of the purchase price in an acquisition that is payable at a future date, either as a fixed amount or contingent on the achievement of specified milestones. Deferred consideration must be recognised at fair value at the acquisition date under IFRS 3 and ASC 805, with subsequent changes in value typically recorded through profit or loss.

Tax deductions available to businesses in the United Kingdom for qualifying expenditure on certain assets, effectively reducing the taxable profit by allowing the cost of the asset to be written off over time. Capital allowances are particularly relevant to intangible asset investment because the UK tax regime provides specific relief for expenditure on intellectual property, patents, know-how, and certain other intangible assets.

Contingent Liability

A potential obligation arising from past events whose existence will be confirmed only by the occurrence or non-occurrence of one or more uncertain future events not wholly within the entity's control, or a present obligation where payment is not probable or the amount cannot be reliably measured.

What is the useful life of an AI model for amortisation purposes?

AI models typically have useful lives of 2-5 years for amortisation, reflecting rapid technological advancement, though the underlying training data and architecture may retain value longer.

What is the difference between finite and indefinite-life intangibles?

Finite-life intangibles (patents, customer lists, licences) are amortised over useful life; indefinite-life intangibles (brands, market position) are tested annually for impairment.

Can you capitalise intangible assets on the balance sheet?

Yes, under IAS 38 and ASC 350, intangible assets can be capitalised when they meet specific recognition criteria — but internally generated goodwill and many R&D costs must be expensed.
