64Spire Healthcare Annual Review 2010Spire Healthcare Limited PartnershipNotes to the financial statementsFor the year ended 31 December 201017. Deferred taxationDeferred tax liabilities/(assets) are analysed as follows:2010£0002009£000Temporary differences on:Property, plant and equipment313,412313,357Derivative financial instruments(56,866)(47,844)Losses and other(16,447)(16,057)240,099249,456Presented as:Deferred tax asset(3,968)(9,215)Deferred tax liability244,067258,671240,099249,456Deferred tax on property, plant and equipment has arisen on differences between the carrying value of the relevant assets and the tax base. Other deferred tax relates to temporary timing differences on non-specific bad debt provisions and expense accruals.Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the period when the asset is realised or the liability settled, based on tax rates that have been enacted or substantively enacted at the balance sheet date. As at the date of the financial statements, the Finance Bill 2010, which includes a reduction in the UK corporate tax rate to 27% from 1 April 2011, has been substantively enacted and so UK deferred tax assets and liabilities have been calculated at this rate. The UK Government intends to reduce the UK corporate income tax rate further, to 23%, which will be enacted in successive Finance Bills. Consequently, the Group will only recognise the impact of the rate change which is substantively enacted at that time in its financial statements. However, for indicative purposes only, the maximum effect of the proposed reduction in the corporate income tax rate is to reduce the deferred tax balance as at 31 December 2010 to £205,000,000.The movement for the year in the net deferred tax liability is as follows:Property, plant and equipment£000Derivative financial instruments£000Losses and other£000Total£00031 December 2008 and 1 January 2009324,826 (58,847)(2,970)263,009 Recognised in income(11,469) - (13,089)(24,558)Other movements2 2 Recognised in other comprehensive income - 11,003 - 11,003 At 31 December 2009 and 1 January 2010313,357 (47,844)(16,057)249,456 On acquisition of subsidiaries66 - (121)(55)Recognised in income(11) - (269)(280)Recognised in other comprehensive income - (9,022) - (9,022)At 31 December 2010313,412 (56,866)(16,447)240,099

Employee Benefit TrustSpire Healthcare Limited is the sponsoring company for the Rozier Employee Benefit Trust, under which certain employees of companies that are under the ownership of the Spire Healthcare Limited Partnership are invited to become members. The Employee Benefit Trust distributes B units in the Spire Healthcare Limited Partnership to members in exchange for cash consideration equal to the market value of the units as at the date of distribution and holds other units to provide for future obligations under employee equity schemes. During the year the consideration paid by employees for B units in the Spire Healthcare Limited Partnership, after deducting amounts relating to units repurchased from leavers, was £33,000 (2009: £114,000). The price paid of £1 per B unit was considered to represent their fair value, as it was equivalent to that paid by external investors. The number of units that have not yet been vested in employees is 881,000 (2009: 914,000).
