b'88 Mercia Asset Management PLC Annual Report and Accounts 2021Notes to the consolidated financial statements continued1. Accounting policies continuedTaxation continuedDeferred tax is the tax expected to be payable or recoverable on differences between the carrying amounts of assets and liabilities in the financial statements and the corresponding tax bases used in the computation of taxable profit, using the balance sheet liability method. Deferred tax liabilities are generally recognised for all taxable temporary timing differences and deferred tax assets are recognised to the extent that it is probable that taxable profits will be available, against which deductible temporary differences can be utilised.Such assets and liabilities are not recognised if the temporary difference arises from the initial recognition of goodwill or from the initial recognition (other than in a business combination) of other assets and liabilities, in a transaction that affects neither the taxable profit nor the accounting profit.Deferred tax liabilities are recognised for taxable temporary differences arising on investments in subsidiaries except where the Group is able to control the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future.Deferred tax assets arising from deductible temporary differences associated with such investments are only recognised to the extent that it is probable that there will be sufficient taxable profits against which to utilise the benefits of the temporary differences and they are expected to reverse in the foreseeable future.The Group primarily seeks to generate capital gains from its holdings in direct investments over the longer term. Capital gains arising from the disposal of direct investments would ordinarily be taxed upon realisation of such investments. However, since the Groups activities are substantially trading in nature, the Directors continue to believe that it qualifies for the Substantial Shareholdings Exemption (SSE). This exemption provides that gains arising on the disposal of qualifying investments are not chargeable to UK corporation tax and, as such, the Group has continued not to recognise a provision for deferred taxation in respect of fair value gains in those investments that meet the qualifying criteria. Gains arising on the disposal of non-qualifying investments would ordinarily give rise to taxable profits for the Group, to the extent that these cannot be offset by the Groups brought forward tax losses.Intangible assetsIdentifiable intangible assets are recognised when the Group controls the assets, it is probable that future economic benefits attributable to the assets will flow to the Group and the fair value of the assets can be measured reliably.Intangible assets represent contractual arrangements in respect of third-party limited partners and other similar investors Funds under Management (FuM) acquired through the acquisition of Enterprise Ventures Group Limited (Enterprise Ventures) and, in respect of FuM, acquired through the acquisition of the Venture Capital Trust (VCT) fund management business of NVM Private Equity LLP (NVM). At the date of acquisition the fair values of these contracts were calculated and subsequently the assets are held at amortised cost. The fair value of the intangible assets arising from the acquisition of Enterprise Ventures is being amortised on a straight-line basis over the expected average duration of the remaining fund management contracts of five years, so as to write off the fair value of the contracts less their estimated residual values. During the year ended 31 March 2021 the Enterprise Ventures intangible became fully amortised. The fair value of the intangible assets arising from the acquisition of the VCT fund management business is being amortised on a straight-line basis over the expected useful life of the fund management contracts.GoodwillGoodwill arising on the acquisition of a subsidiary represents the excess of the fair value of the consideration given over the fair value of the identifiable net assets acquired. Goodwill is not amortised but is reviewed annually for impairment in accordance with IAS 36, Impairment of Assets.Property, plant and equipmentTangible assets are stated at cost less accumulated depreciation and any recognised impairment loss. Depreciation is recognised so as to write off the cost or valuation of assets less their residual values over their expected useful lives, using the straight-line method, on the following basis:Furniture, fixtures and office equipment33%Leasehold improvementsover the remaining life of the leaseThe estimated useful lives, residual values and depreciation method are reviewed at the end of each reporting period, with the effect of any changes in estimate accounted for on a prospective basis.'
