RBS Group • Annual Report and Accounts 2006
Financial statements
present value methodology taking into account the level of
arrears, security, past loss experience, credit scores and
defaults based on portfolio trends. The most significant factors
in establishing these provisions are the expected loss rates and
the related average life. These portfolios include credit card
receivables and other personal advances including mortgages.
The future credit quality of these portfolios is subject to
uncertainties that could cause actual credit losses to differ
materially from reported loan impairment provisions. These
uncertainties include the economic environment, notably interest
rates and their effect on customer spending, the unemployment
level, payment behaviour and bankruptcy trends.
Pensions
The Group operates a number of defined benefit pension
schemes as described in Note 3 on the accounts. The assets
of the schemes are measured at their fair value at the balance
sheet date. Scheme liabilities are measured using the
projected unit method, which takes account of projected
earnings increases, using actuarial assumptions that give the
best estimate of the future cash flows that will arise under the
scheme liabilities. These cash flows are discounted at the
interest rate applicable to high-quality corporate bonds of the
same currency and term as the liabilities. Any surplus or deficit
of scheme assets over liabilities is recognised in the balance
sheet as an asset (surplus) or liability (deficit). In determining the
value of scheme liabilities, assumptions are made as to price
inflation, dividend growth, pension increases, earnings growth
and employees. There is a range of assumptions that could be
adopted in valuing the schemes’ liabilities. Different assumptions
could significantly alter the amount of the deficit recognised in
the balance sheet and the pension cost charged to the income
statement. The assumptions adopted for the Group’s pension
schemes are set out in Note 3 on the accounts. The pension
deficit recognised in the balance sheet at 31 December 2006
was £1,992 million (2005 – £3,735 million).
Fair value
Financial instruments classified as held-for-trading or
designated as at fair value through profit or loss and financial
assets classified as available-for-sale are recognised in the
financial statements at fair value. All derivatives are measured at
fair value. In the balance sheet, financial assets carried at fair
value are included within Treasury and other eligible bills, Loans
and advances to banks, Loans and advances to customers,
Debt securities and Equity shares as appropriate. Financial
liabilities carried at fair value are included within the captions
Deposits by banks, Customer accounts, Debt securities in issue
and Subordinated liabilities. Derivative assets and Derivative
liabilities are shown separately on the face of the balance
sheets. Gains or losses arising from changes in fair value of
financial instruments classified as held-for-trading or designated
as at fair value through profit or loss are included in the income
statement. Unrealised gains and losses on available-for-sale
financial assets are recognised directly in equity unless an
impairment loss is recognised. The carrying value of a financial
asset or a financial liability carried at cost or amortised cost that
is the hedged item in a qualifying hedge relationship is
adjusted by the gain or loss attributable to the hedged risk.
Fair value is the amount for which an asset could be exchanged,
or a liability settled, between knowledgeable, willing parties in
an arm's length transaction. Fair values are determined by
reference to observable market prices where available and
reliable. Where representative market prices for an instrument
are not available or are unreliable because of poor liquidity, the
fair value is derived from prices for its components using
appropriate pricing or valuation models that are based on
independently sourced market parameters, including interest
rate yield curves, option volatilities and currency rates.
Financial assets carried at fair value include government, asset
backed and corporate debt securities, reverse repos, loans,
corporate equity shares and derivatives. Financial liabilities
carried at fair value include deposits, repos, short positions in
securities and debt securities issued. Fair value for a substantial
proportion of these instruments is based on observable market
prices or derived from observable market parameters. Where
observable prices are not available, fair value is based on
appropriate valuation techniques or management estimates.
The Group’s derivative products include swaps, forwards,
futures and options. Exchange traded instruments are valued
using quoted prices. The fair value of over-the-counter
instruments is derived from pricing models which take account
of contract terms, including maturity, as well as quoted market
parameters such as interest rates and volatilities. Most of the
Group’s pricing models do not entail material subjectivity
because the methodologies utilised do not incorporate
significant judgement and the parameters included in the
models can be calibrated to actively quoted market prices.
Values established from pricing models are adjusted for credit
risk, liquidity risk and future servicing costs.
A negligible proportion of the Group’s trading derivatives are
valued directly from quoted prices, the majority being valued
using appropriate valuation techniques. The fair value of
substantially all securities positions carried at fair value is
determined directly from quoted prices.
Details of financial instruments carried at fair value are given in
Note 35 on the accounts.
General insurance claims
The Group makes provision for the full cost of settling outstanding
claims arising from its general insurance business at the
balance sheet date, including claims estimated to have been
incurred but not yet reported at that date and claims handling
expenses. General insurance claims provisions amounted to
£5,247 million at 31 December 2006 (2005 – £4,913 million).
Provisions are determined by management based on
experience of claims settled and on statistical models which
require certain assumptions to be made regarding the
incidence, timing and amount of claims and any specific
factors such as adverse weather conditions. In order to calculate
the total provision required, the historical development of
claims is analysed using statistical methodology to extrapolate,
within acceptable probability parameters, the value of
outstanding claims at the balance sheet date. Also included in
the estimation of outstanding claims are other assumptions
such as the inflationary factor used for bodily injury claims
