NOTES TO THE FINANCIAL STATEMENTS (CONTD.) Year ended 31 December 2015
The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered. Deferred tax is calculated at the tax rates that have been enacted or substantively enacted at the statement of financial position date. Deferred tax is charged or credited in the statement of comprehensive income, except when it relates to items charged or credited in other comprehensive income, in which case the deferred tax is also dealt with in other comprehensive income. The measurement of deferred tax liabilities and assets reflects the tax consequences that would follow from the manner in which the Group expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities. Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax liabilities and when they relate to income taxes levied by the same taxation authority and the Group intends to settle its current tax assets and liabilities on a net basis. Current and deferred tax are recognised in profit or loss, except when they relate to items that are recognised in other comprehensive income or directly in equity, in which case, the current and deferred tax are also recognised in other comprehensive income or directly in equity, respectively. When current tax or deferred tax arises from the initial accounting for a business combination, the tax effect is included in the accounting for the business combination.
Provisions Provisions are recognised when the Group has a present legal or constructive obligation as a result of a past event, and where it is probable that the Group will be required to settle that obligation and the amount can be reliably estimated. The amount recognised as a provision is the best estimate of the consideration required to settle the present obligation at the statement of financial position date, taking into account the risks and uncertainties surrounding the obligation. Where a provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows (when the time value of money is material). Contingent liabilities acquired in a business combination are initially valued at fair value at the acquisition date. At the end of subsequent reporting periods, such contingent liabilities are measured at the higher of the amount that would be recognised in accordance with IAS 37 and the amount initially recognised.
Financial instruments Financial assets and financial liabilities are recognised on the Group’s statement of financial position when the Group becomes a party to the contractual provisions of the instrument. The principal financial assets and liabilities of the Group are as follows:
(a) Loans and receivables Trade receivables, loans and other receivables that have fixed or determinable payments that are not quoted in an active market are classified as loans and receivables. Trade receivables do not carry any interest and are stated at their initial value reduced by appropriate allowances for estimated irrecoverable amounts. Provisions against trade receivables and amounts recoverable on contracts are made when objective evidence is received that the Group will not be able to collect all amounts due to it in accordance with the original terms of those receivables. The amount of the write down is determined as the difference between the asset’s carrying amount and the present value of estimated future cash flows. Individually significant balances are reviewed separately for impairment based on the credit terms agreed with the customer. Other balances are reviewed in aggregate. (b) Cash and cash equivalents Cash and cash equivalents comprise cash balances and call deposits with a maturity of three months or less. Bank overdrafts are presented as current liabilities to the extent that there is no right of offset with cash balances. (c) Investments Investments in subsidiary undertakings are stated at cost less any provision for impairment. Any contingent consideration is recognised as an accrual at the acquisition date and is measured at the present value of the expected settlement using a pre-tax discount rate that reflects current market assessment of the time value of money. The increase in the accrual due to the passage of time is recognised as an interest expense. Any change to the value of contingent consideration identified within 12 months of the year end in which the acquisition occurred is reflected in the original cost of the investment. Subsequent changes to the value of contingent consideration are reflected in the statement of comprehensive income in the Group accounts. Where the Company or its subsidiaries has significant influence over an entity, normally being more than 20% and less than 50%, then that investment is classified as an associate and is equity accounted for. The Company assesses investments for impairment whenever events or changes in circumstances indicate that the carrying value of an investment may have suffered an impairment loss. If any such indication exists the Company makes an estimate of the recoverable amount. The recoverable amount is the higher of fair value less costs to sell and value in use. Value in use represents the discounted net present value of expected future cash flows. If the recoverable amount is less than the value of the investment, the investment is considered to be impaired and is written down to its recoverable amount, and an impairment loss is recognised immediately in the statement of comprehensive income of the Company.
