Tesco PLC Annual Report and
Financial Statements 2008 49
Pensions and similar obligations
The Group accounts for pensions and other post-employment benefits
(principally private healthcare) under IAS 19 ‘Employee Benefits’.
In respect of defined benefit plans, obligations are measured at discounted
present value (using the projected unit credit method) whilst plan assets
are recorded at fair value. The operating and financing costs of such plans
are recognised separately in the Group Income Statement; service costs
are spread systematically over the expected service lives of employees and
financing costs are recognised in the periods in which they arise. Actuarial
gains and losses are recognised immediately in the Group Statement of
Recognised Income and Expense.
Payments to defined contribution schemes are recognised as an expense
as they fall due.
Share-based payments
Employees of the Group receive part of their remuneration in the form
of share-based payment transactions, whereby employees render services
in exchange for shares or rights over shares (equity-settled transactions)
or in exchange for entitlements to cash payments based on the value of
the shares (cash-settled transactions).
The fair value of employee share option plans is calculated at the grant
date using the Black-Scholes model. In accordance with IFRS 2 ‘Share-based
payment’, the resulting cost is charged to the Group Income Statement
over the vesting period. The value of the charge is adjusted to reflect
expected and actual levels of vesting.
Taxation
The tax expense included in the Group Income Statement consists of
current and deferred tax.
Current tax is the expected tax payable on the taxable income for the year,
using tax rates enacted or substantively enacted by the Balance Sheet date.
Tax is recognised in the Group Income Statement except to the extent that
it relates to items recognised directly in equity, in which case it is recognised
in equity.
Deferred tax is provided using the Balance Sheet liability method,
providing for temporary differences between the carrying amounts of
assets and liabilities for financial reporting purposes and the amounts
used for taxation purposes.
Deferred tax is calculated at the tax rates that have been enacted or
substantively enacted by the Balance Sheet date. Deferred tax is charged
or credited in the Group Income Statement, except when it relates to items
charged or credited directly to equity, in which case the deferred tax is also
recognised in equity.
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.
The carrying amount of deferred tax assets is reviewed at each Balance
Sheet 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 assets and liabilities are offset against each other when
there is a legally enforceable right to set-off current taxation assets against
current taxation liabilities and it is the intention to settle these on a
net basis.
Foreign currencies
Transactions in foreign currencies are translated at the exchange rate on
the date of the transaction. At each Balance Sheet date, monetary assets
and liabilities that are denominated in foreign currencies are retranslated
at the rates prevailing on the Balance Sheet date. All differences are taken
to the Group Income Statement for the period.
The financial statements of foreign subsidiaries are translated into Pounds
Sterling according to the functional currency concept of IAS 21 ‘The Effects
of Changes in Foreign Exchange Rates’. Since the majority of consolidated
companies operate as independent entities within their local economic
environment, their respective local currency is the functional currency.
Therefore, assets and liabilities of overseas subsidiaries denominated in
foreign currencies are translated at exchange rates prevailing at the date
of the Group Balance Sheet; profits and losses are translated into Pounds
Sterling at average exchange rates for the relevant accounting periods.
Exchange differences arising, if any, are classified as equity and transferred
to the Group’s translation reserve. Such translation differences are
recognised as income or expenses in the period in which the operation
is disposed of.
Goodwill and fair value adjustments arising on the acquisition of a
foreign entity are treated as assets and liabilities of the foreign entity and
translated at the closing rate.
Financial instruments
Financial assets and financial liabilities are recognised on the Group’s
Balance Sheet when the Group becomes a party to the contractual
provisions of the instrument.
Trade receivables
Trade receivables are non interest-bearing and are recognised initially
at fair value, and subsequently at amortised cost using the effective
interest rate method, reduced by appropriate allowances for estimated
irrecoverable amounts.
Investments
Investments are recognised at trade date. Investments are classified as
either held for trading or available-for-sale, and are recognised at fair value.
For held for trading investments, gains and losses arising from changes
in fair value are recognised in the Group Income Statement.
For available-for-sale investments, gains and losses arising from changes
in fair value are recognised directly in equity, until the security is disposed
of or is determined to be impaired, at which time the cumulative gain or
loss previously recognised in equity is included in the net result for the period.
Interest calculated using the effective interest rate method is recognised
in the Group Income Statement. Dividends on an available-for-sale equity
instrument are recognised in the Group Income Statement when the
entity’s right to receive payment is established.
Financial liabilities and equity
Financial liabilities and equity instruments are classified according to
the substance of the contractual arrangements entered into. An equity
instrument is any contract that gives a residual interest in the assets of
the Group after deducting all of its liabilities.
