INTERNATIONAL FINANCIAL REPORTING STANDARDS

The annual accounts have, for the first time, been prepared in accordance with International Financial Reporting Standards ('IFRS') adopted by the International Accounting Standards Board ('IASB'), and interpretations issued by the International Financial Reporting Interpretations Committee of the IASB and endorsed by the European Union. The date of transition to IFRS for NatWest and the date of its opening IFRS balance sheet was 1 January 2004.

In preparing its results, NatWest has applied IFRS extant at 31 December 2005.

As a result of continued amendments to IAS 39 'Financial Instruments: Recognition and Measurement' during 2004 and into 2005 the Group was not in a position fully to implement this standard for statutory reporting from 1 January 2004. NatWest has therefore taken advantage of the option in IFRS 1 'First-time Adoption of International Financial Reporting Standards' to implement IAS 39, together with IAS 32 'Financial Instruments: Disclosure and Presentation' and IFRS 4 'Insurance Contracts', from 1 January 2005 without restating its 2004 profit and loss account and balance sheet. The results for 2005 and 2004 are therefore not directly comparable.

FINANCIAL HIGHLIGHTS

NatWest Home Loans Limited was transferred to The Royal Bank of Scotland plc on 31 December 2005 at neither a profit nor a loss to NatWest Group and its results are shown as discontinued.

Operating profit before tax from continuing operations increased by 9% from £3,000 million to £3,264 million.

Total income from continuing operations was £8,429 million compared with £7,745 million in the prior year, an increase of £684 million, 9%. Operating expenses from continuing operations increased by £298 million, 7% to £4,413 million.

Provisions for impairment in continuing operations at £752 million were £122 million higher.

Total assets were up £63.4 billion from £197.2 billion to £260.6 billion. Loans and advances to customers (excluding £26.9 billion relating to NatWest Home Loans which was sold on 31 December 2005) were up 53%, £55.2 billion at £159.9 billion and loans and advances to banks increased by £26.0 billion to £56.0 billion, reflecting the implementation of IAS 32 and IAS 39 on 1 January 2005 and business growth.

The directors are satisfied with the progress of the Group in 2005 and do not expect any significant change in the future.

NOTES

1.

Adoption of International Financial Reporting Standards ("IFRS")

NatWest prepared its 2004 consolidated financial statements in accordance with accounting standards issued by the UK Accounting Standards Board, the pronouncements of the Urgent Issues Task Force, relevant Statements of Recommended Accounting Practice and in compliance with the Companies Act 1985. NatWest will henceforth prepare its consolidated financial statements in accordance with International Financial Reporting Standards adopted by the International Accounting Standards Board ("IASB"), and interpretations issued by the International Financial Reporting Interpretations Committee of the IASB (together "IFRS"). The standards, adopted for the first time for the purpose of preparing consolidated financial statements for the year ending 31 December 2005, are those issued by the IASB and endorsed by the EU as at 31 December 2005. The EU has not endorsed IAS 39 as issued by the IASB. It has relaxed some of the hedging requirements. NatWest has not taken advantage of this relaxation. A reconciliation of equity as at 31 December 2004 and of profit for 2004 under previous GAAP to IFRS is included in this announcement.

2.	Basis of preparation
	The statutory accounts have been prepared in accordance with IFRS.

3.

Accounting policies

NatWest's provisional IFRS accounting policies and a description of the key differences between UK GAAP and IFRS accounting policies were included in NatWest's interim results announcement issued on 28 September 2005. Subsequently, NatWest has adopted the Amendment to IAS 39 'The Fair Value Option' issued by the IASB in June 2005 with effect from 1 January 2005. This amendment allows financial assets and financial liabilities to be designated as at fair value through profit or loss but only if it (a) eliminates or significantly reduces a measurement or recognition inconsistency, or (b) is applied to a group of financial assets, financial liabilities or both that is managed and its performance evaluated on a fair value basis, or (c) relates to a financial asset or financial liability with an embedded derivative; unless it is clear that accounting for the embedded derivative separately from the host is prohibited by IAS 39. Implementation of the amended fair value option did not have a material effect on shareholders' funds as at 1 January 2005.
