The preparation of the consolidated financial statements requires management to make judgements, estimates and assumptions that affect the application of policies and reported amounts of assets and liabilities, income and expenses. The estimates and associated assumptions are based on historical experience and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis of making judgements about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from the estimates.
The judgement and key sources of estimation uncertainty that have a significant effect on the amounts recognised in the financial statements are detailed below:
Allowances Against the Carrying Value of Inventories
The Group reviews the market value of and demand for its inventories on a periodic basis to ensure that recorded inventory is stated at the lower of cost and net realisable value. In assessing the ultimate realisation of inventories, the Group is required to make judgements as to future demand requirements and to compare these with the current or committed inventory levels. Assumptions have been made relating to the timing and success of product ranges, which would impact estimated demand and selling prices.
Sensitivities to the assumptions for specific product lines are not expected by management to result in a material change in the overall allowances.
Intangible Asset Valuations
The measurement of fair values on a business combination requires the recognition and measurement of the identifiable assets, liabilities and contingent liabilities. The key judgements involved are the identification of which intangible assets meet the recognition criteria as set out in IAS 38, the fair values attributable to those intangible assets, excluding any buyer-specific synergies, and the useful lives of individual intangible assets. The useful lives of intangibles assets relating to customer relationships involves judgement as to customer retention rates applicable.
Impairment of Assets
Goodwill and other assets are subject to impairment reviews based on whether current or future events and circumstances suggest that their recoverable value may be less than their carrying value. Recoverable amount is based on a calculation of expected future cash flows, which includes management assumptions and estimates of future performance. Details of the assumptions used in the impairment review of goodwill and other assets are explained in note 11.
The carrying amount of these assets and liabilities can be seen in the notes to the financial statements.
