that it is probable that future taxable profits will be available against which deductible temporary differences can
be utilised.
Deferred tax is calculated using the tax rates expected to apply in the periods in which the assets will be realised
or the liabilities settled, based on tax rates and laws enacted, or substantively enacted, by the balance sheet date.
Deferred tax assets and liabilities are offset when they arise in the same tax reporting group and relate to income
taxes levied by the same taxation authority, and when HSBC has a legal right to offset.
Deferred tax relating to actuarial gains and losses on post-employment benefits is recognised in other
comprehensive income. Deferred tax relating to share-based payment transactions is recognised directly in
equity to the extent that the amount of the estimated future tax deduction exceeds the amount of the related
cumulative remuneration expense. Deferred tax relating to fair value re-measurements of available-for-sale
investments and cash flow hedging instruments which are charged or credited directly to other comprehensive
income, is also charged or credited to other comprehensive income and is subsequently recognised in the income
statement when the deferred fair value gain or loss is recognised in the income statement.
(t) Pension and other post-employment benefits
HSBC operates a number of pension and other post-employment benefit plans throughout the world. These plans
include both defined benefit and defined contribution plans and various other post-employment benefits such as
post-employment healthcare.
Payments to defined contribution plans and state-managed retirement benefit plans, where HSBC’s obligations
under the plans are equivalent to a defined contribution plan, are charged as an expense as they fall due.
The defined benefit pension costs and the present value of defined benefit obligations are calculated at the
reporting date by the schemes’ actuaries using the Projected Unit Credit Method. The net charge to the income
statement mainly comprises the current service cost, plus the unwinding of the discount rate on plan liabilities,
less the expected return on plan assets, and is presented in operating expenses. Past service costs are charged
immediately to the income statement to the extent that the benefits have vested, and are otherwise recognised
on a straight-line basis over the average period until the benefits vest. Actuarial gains and losses comprise
experience adjustments (the effects of differences between the previous actuarial assumptions and what has
actually occurred), as well as the effects of changes in actuarial assumptions. Actuarial gains and losses are
recognised in other comprehensive income in the period in which they arise.
The defined benefit liability recognised in the balance sheet represents the present value of defined benefit
obligations adjusted for unrecognised past service costs and reduced by the fair value of plan assets. Any net
defined benefit surplus is limited to unrecognised past service costs plus the present value of available refunds
and reductions in future contributions to the plan.
The cost of obligations arising from other post-employment defined benefit plans, such as defined benefit health-
care plans, are accounted for on the same basis as defined benefit pension plans.
(u) Share-based payments
The cost of share-based payment arrangements with employees is measured by reference to the fair value of
equity instruments on the date they are granted and recognised as an expense on a straight-line basis over the
vesting period, with a corresponding credit to the ‘Share-based payment reserve’. The vesting period is the
period during which all the specified vesting conditions of a share-based payment arrangement are to be
satisfied. The fair value of equity instruments that are made available immediately, with no vesting period
attached to the award, are expensed immediately.
Fair value is determined by using appropriate valuation models, taking into account the terms and conditions
upon which the equity instruments were granted. Vesting conditions include service conditions and performance
conditions; any other features of a share-based payment arrangement are non-vesting conditions. Market
performance conditions and non-vesting conditions are taken into account when estimating the fair value of
equity instruments at the date of grant, so that an award is treated as vesting irrespective of whether the market
performance condition or non-vesting condition is satisfied, provided all other vesting conditions are satisfied.
Vesting conditions, other than market performance conditions, are not taken into account in the initial estimate
of the fair value at the grant date. They are taken into account by adjusting the number of equity instruments
