Interest income is recognised on available-for-sale debt securities using the effective interest rate, 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. Impairment losses are recognised if, and only if, there is objective evidence
of impairment as a result of one or more events that occurred after the initial recognition of the financial
asset (a ‘loss event’) and that loss event (or events) has an impact on the estimated future cash flows of the
financial asset that can be reliably estimated.
If the available-for-sale financial asset is impaired, the difference between the financial asset’s acquisition
cost (net of any principal repayments and amortisation) and the current fair value, less any previous
impairment loss recognised in the income statement, is removed from other comprehensive income and
recognised in the income statement.
Impairment losses for available-for-sale debt securities are recognised within ‘Loan impairment charges and
other credit risk provisions’ in the income statement and impairment losses for available-for-sale equity
securities are recognised within ‘Gains less losses from financial investments’ in the income statement. The
impairment methodologies for available-for-sale financial assets are set out in more detail below.
– Available-for-sale debt securities. When assessing available-for-sale debt securities for objective
evidence of impairment at the reporting date, HSBC considers all available evidence, including
observable data or information about events specifically relating to the securities which may result in a
shortfall in recovery of future cash flows. These events may include a significant financial difficulty of
the issuer, a breach of contract such as a default, bankruptcy or other financial reorganisation, or the
disappearance of an active market for the debt security because of financial difficulties relating to the
issuer.
These types of specific event and other factors such as information about the issuers’ liquidity, business
and financial risk exposures, levels of and trends in default for similar financial assets, national and
local economic trends and conditions, and the fair value of collateral and guarantees may be considered
individually, or in combination, to determine if there is objective evidence of impairment of a debt
security.
In addition, when assessing available-for-sale asset-backed securities (‘ABS’s) for objective evidence of
impairment, HSBC considers the performance of underlying collateral and the extent and depth of
market price declines. Changes in credit ratings are considered but a downgrade of a security’s credit
rating is not, of itself, evidence of impairment. The primary indicators of potential impairment are
considered to be adverse fair value movements and the disappearance of an active market for a security.
ABS impairment methodologies are described in more detail in ‘Securitisation exposures and other
structured products’ on page 128.
– Available-for-sale equity securities. Objective evidence of impairment for available-for sale equity
securities may include specific information about the issuer as detailed above, but may also include
information about significant changes in technology, markets, economics or the law that provides
evidence that the cost of the equity securities may not be recovered.
A significant or prolonged decline in the fair value of the asset below its cost is also objective evidence
of impairment. In assessing whether it is significant, the decline in fair value is evaluated against the
original cost of the asset at initial recognition. In assessing whether it is prolonged, the decline is
evaluated against the period in which the fair value of the asset has been below its original cost at initial
recognition.
Once an impairment loss has been recognised on an available-for-sale financial asset, the subsequent
accounting treatment for changes in the fair value of that asset differs depending on the nature of the
available-for-sale financial asset concerned:
– for an available-for-sale debt security, a subsequent decline in the fair value of the instrument is
recognised in the income statement when there is further objective evidence of impairment as a result
of further decreases in the estimated future cash flows of the financial asset. Where there is no further
