Interest income is recognised on available-for-sale securities using the effective interest rate method,
calculated over the asset’s expected life. Premiums and/or discounts arising on the purchase of dated
investment securities are included in the calculation of their effective interest rates. Dividends are
recognised in the income statement when the right to receive payment has been established.
At each balance sheet date an assessment is made of whether there is any objective evidence of impairment
in the value of a financial asset or group of assets. This usually arises when circumstances are such that an
adverse effect on future cash flows from the asset or group of assets can be reliably estimated. If an
available-for-sale security is impaired, the cumulative loss (measured as the difference between the asset’s
acquisition cost (net of any principal repayments and amortisation) and its current fair value, less any
impairment loss on that asset previously recognised in the income statement) is removed from equity and
recognised in the income statement. Reversals of impairment losses are subject to contrasting treatments
depending on the nature of the instrument concerned:
– if the fair value of a debt instrument classified as available-for-sale increases in a subsequent period,
and the increase can be objectively related to an event occurring after the impairment loss was
recognised in the income statement, the impairment loss is reversed through the income statement;
– impairment losses recognised in the income statement on equity instruments are not reversed through
the income statement.
(ii) Held-to-maturity investments are non-derivative financial assets with fixed or determinable payments and
fixed maturities that HSBC positively intends, and is able, to hold until maturity. Held-to-maturity
investments are initially recorded at fair value plus any directly attributable transaction costs, and are
subsequently measured at amortised cost using the effective interest rate method, less any impairment
losses.
(j) Sale and repurchase agreements (including stock lending and borrowing)
When securities are sold subject to a commitment to repurchase them at a predetermined price (‘repos’), they
remain on the balance sheet and a liability is recorded in respect of the consideration received. Securities
purchased under commitments to sell (‘reverse repos’) are not recognised on the balance sheet and the
consideration paid is recorded in ‘Loans and advances to banks’ or ‘Loans and advances to customers’ as
appropriate. The difference between the sale and repurchase price is treated as interest and recognised over the
life of the agreement.
Securities lending and borrowing transactions are generally secured, with collateral taking the form of securities
or cash advanced or received. The transfer of securities to counterparties under these agreements is not normally
reflected on the balance sheet. Cash collateral advanced or received is recorded as an asset or a liability
respectively.
Securities borrowed are not recognised on the balance sheet. If they are sold on to third parties, an obligation to
return the securities is recorded as a trading liability and measured at fair value, and any gains or losses are
included in ‘Net trading income’.
(k) Derivatives and hedge accounting
Derivatives are recognised initially, and are subsequently remeasured, at fair value. Fair values of exchange-
traded derivatives are obtained from quoted market prices. Fair values of over-the-counter derivatives are
obtained using valuation techniques, including discounted cash flow models and option pricing models.
Derivatives may be embedded in other financial instruments, for example, a convertible bond with an embedded
conversion option. Embedded derivatives are treated as separate derivatives when their economic characteristics
and risks are not clearly and closely related to those of the host contract; the terms of the embedded derivative
would meet the definition of a stand-alone derivative if they were contained in a separate contract; and the
combined contract is not held for trading or designated at fair value. These embedded derivatives are measured
at fair value with changes therein recognised in the income statement.
Derivatives are classified as assets when their fair value is positive, or as liabilities when their fair value is
negative. Derivative assets and liabilities arising from different transactions are only offset if the transactions are
