Current tax is the expected tax payable on the taxable income for the year and any adjustment to tax payable in respect of previous years.

Deferred tax is provided using the balance sheet liability method, providing for tax on any temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes using tax rates enacted or substantially enacted at the balance sheet date.

No deferred tax is provided on temporary differences arising on investments in subsidiaries, joint ventures and associates, where the Group is able to control the timing on the reversal and it is probable that the temporary difference will not reverse in the foreseeable future. Deferred tax assets are recognised for deductible temporary differences to the extent that it is probable that taxable profit will be available against which they can be utilised.

Business combinations and goodwill
On the acquisition of a business, fair values are attributed to the net assets acquired. Goodwill arises where the fair value of the consideration given for a business exceeds the fair value of such net assets. Goodwill arising on acquisitions is capitalised and reviewed for impairment at least annually. Any impairment is recognised immediately in the income statement and is not subsequently reversed. On disposal of a subsidiary, associate or jointly controlled entity, the attributable amount of goodwill is included in the determination of profit or loss on disposal. Goodwill arising on acquisitions before the date of transition to IFRS has been retained at the previous UK GAAP amounts subject to being tested for impairment at that date. Goodwill written off to reserves under UK GAAP prior to 1998 has not been reinstated and is not included in determining any subsequent profit or loss on disposal.
