asset investments
Under US
GAAP, investments in debt securities would be classified as either
trading, available-for-sale or held-to-maturity. Trading investments
would be stated at fair values and the unrealised gains and losses
would be included in income. Securities classified as available-for-sale
would be stated at fair values, with unrealised gains and losses,
net of deferred taxes, reported in shareholders equity.
Debt securities classified as held-to-maturity would be stated
at amortised cost. The following analyses do not include securities
with original maturities of less than three months.
