FINANCIAL REVIEW

Profit

Profit before tax was up 1%, from £3,411 million to £3,456 million. The Group transferred its home mortgage business, National Westminster Home Loans Limited, to The Royal Bank of Scotland plc on 31 December 2005 and the results of this entity have been classified as ‘Discontinued’ in 2005. Profit from continuing operations increased by £192 million, 6%, reflecting organic income growth.

Total income

The Group achieved strong organic growth in income during 2006. Total income was up 8% or £676 million to £9,326 million. Total income from continuing operations was up £897 million, 11%. This growth was reflected across all divisions and was particularly strong in UK Corporate Banking, Retail, Wealth Management and Ulster Bank.

Net interest income was flat at £4,449 million. Net interest income from continuing operations rose by 5%, £200 million and represents 48% of total income (2005 – 50%).

Non-interest income increased 16% to £4,877 million. Non-interest income from continuing operations was up 17%, £697 million and represents 52% of total income (2005 – 50%). Within non-interest income, fees and commissions receivable increased by 6% to £3,928 million and fees and commissions payable were stable at £960 million. Income from trading activities increased by 80% to £1,458 million while other operating income decreased by 29% to £451 million.

Operating expenses

Operating expenses rose by 12% to £5,018 million. Operating expenses from continuing operations increased by 14% to support business expansion.

Cost: income ratio

The Group’s cost: income ratio was 53.8% compared with 52.4% for continuing operations in 2005.

Impairment losses

Impairment losses were £852 million compared with £756 million in 2005, an increase of 13%. Higher provisions in Retail Markets in respect of unsecured personal loans and credit cards and in Ulster Bank due to growth in lending were partially offset by lower impairment losses in Corporate Markets where credit conditions have remained benign.

Integration

Integration costs, which relate to the integration of First Active, were £67 million compared with £163 million in 2005.

Dividends

Dividends totalling £1,500 million (2005 - £350 million) were paid to the holding company during the year.

Balance sheet

Total assets were £290.7 billion at 31 December 2006, 12% higher than total assets of £260.6 billion at 31 December 2005. Lending to customers, excluding repurchase agreements and stock borrowing (“reverse repos”), increased by 12% or £18.1 billion to £162.9 billion. Customer deposits, excluding repurchase agreements and stock lending (“repos”), grew by 13% or £18.2 billion to £155.4 billion.

The directors are satisfied with the progress of the Group in 2006 and do not expect any significant change in the future.

OVERVIEW OF CONSOLIDATED BALANCE SHEET

Total assets of £290.7 billion at 31 December 2006 were up £30.1 billion, 12%, compared with 31 December 2005, reflecting business growth.

Loans and advances to banks increased by £5.6 billion, 10%, to £61.6 billion. Growth in bank placings, up £7.9 billion, 18%, to £50.8 billion, were partially offset by a reduction in reverse repurchase agreements and stock borrowing (“reverse repos”), down £2.3 billion, 18% to £10.8 billion.

Loans and advances to customers were up £22.5 billion, 14%, to £182.4 billion. Lending, excluding reverse repos, rose by £18.1 billion, 12% to £162.9 billion reflecting organic growth across all divisions. Reverse repos increased by 29%, £4.4 billion to £19.5 billion.

Debt securities increased by £3.5 billion, 12%, to £32.3 billion, principally due to increased trading book holdings in Corporate Markets.

Equity shares rose by £0.3 billion, 41%, to £1.2 billion, reflecting the increase in the fair value of available-for-sale securities.

Derivatives, assets and liabilities, decreased reflecting the effects of interest and exchange rates.

Prepayments, accrued income and other assets were down £0.9 billion, 29% to £2.2 billion.

Deposits by banks rose by £0.3 billion, 1% to £46.3 billion. Increased repurchase agreements and stock lending (“repos”), up £0.8 billion to £20.4 billion were offset by lower inter-bank deposits, down £0.5 billion, 2% at £25.9 billion.

Customer accounts were up £23.3 billion, 15% at £181.2 billion. Within this, repos increased £5.1 billion, 25% to £25.8 billion. Excluding repos, deposits rose by £18.2 billion, 13%, to £155.4 billion with good growth in all divisions.

Debt securities in issue increased by £3.5 billion, 33%, to £14.3 billion.

The increase in settlement balances and short positions, up £2.7 billion, 13%, to £24.3 billion, reflected growth in customer activity.

Accruals, deferred income and other liabilities increased £0.5 billion, 15% to £4.1 billion.

Subordinated liabilities were down £1.0 billion, 15% to £5.6 billion. The issue of £0.1 billion dated loan capital was offset by the redemption of £0.4 billion dated and £0.3 billion undated loan capital and £0.4 million principally relating to exchange rate movements.

Shareholders’ equity increased by £0.7 billion, 8% to £10.2 billion. The profit for the period of £2.6 billion was partly offset by the payment of ordinary dividend, £1.5 billion and £0.4 billion resulting principally from exchange rate movements.

5. Litigation

Proceedings, including a consolidated class action, have been brought in the United States against a large number of defendants, including the Group, following the collapse of Enron. The claims against the Group could be significant but are largely unquantified. The Group considers that it has substantial and credible legal and factual defences to these claims and it continues to defend them vigorously. A court ordered mediation commenced in September 2003 but no material progress has been made towards a resolution of the claims, although a number of other defendants have reached settlements in the principal class action. The Group is unable reliably to estimate the possible loss in relation to these matters or the effect that the possible loss might have on the Group’s consolidated net assets or its operating results or cashflows in any particular period. In addition, pursuant to requests received from the US Securities and Exchange Commission and the Department of Justice, the Group has provided copies of Enron-related materials to these authorities and has co-operated fully with them.

Members of the Group are engaged in other litigation in the United Kingdom and a number of overseas jurisdictions, including the United States, involving claims by and against them arising in the ordinary course of business. The Group has reviewed these other actual, threatened and known potential claims and proceedings and, after consulting with its legal advisers, is satisfied that the outcome of these other claims and proceedings will not have a material adverse effect on its consolidated net assets, operating results or cash flows in any particular period.
