Review Report

INDEPENDENT REVIEW REPORT TO SANTANDER UK PLC

We have been engaged by Santander UK plc (the 'Company') to review the condensed set of financial statements in the half-yearly financial report for the six months ended 30 June 2013 comprising the Condensed Consolidated Income Statement, the Condensed Consolidated Statement of Comprehensive Income, the Condensed Consolidated Balance Sheet, the Condensed Consolidated Statement of Changes in Equity, the Condensed Consolidated Cash Flow Statement, the related Notes 1 to 30, the information on pages 36 to 95 of the Risk Management Report in the Business Review except for those items marked as unreviewed, together the Condensed Consolidated Interim Financial Statements. We have read the other information contained in the half-yearly financial report and considered whether it contains any apparent misstatements or material inconsistencies with the information in the condensed set of financial statements.

This report is made solely to the Company in accordance with International Standard on Review Engagements (UK and Ireland) 2410 "Review of Interim Financial Information Performed by the Independent Auditor of the Entity" issued by the Auditing Practices Board. Our work has been undertaken so that we might state to the Company those matters we are required to state to it in an independent review report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the Company, for our review work, for this report, or for the conclusions we have formed.

Directors' responsibilities

The half-yearly financial report is the responsibility of, and has been approved by, the directors. The directors are responsible for preparing the half-yearly financial report in accordance with the Disclosure and Transparency Rules of the United Kingdom's Financial Conduct Authority.

As disclosed in Note 1, the annual financial statements of the Company are prepared in accordance with IFRSs as adopted by the European Union. The condensed set of financial statements included in this half-yearly financial report has been prepared in accordance with International Accounting Standard 34, "Interim Financial Reporting," as adopted by the European Union.

Our responsibility

Our responsibility is to express to the Company a conclusion on the condensed set of financial statements in the half-yearly financial report based on our review.

Scope of Review

We conducted our review in accordance with International Standard on Review Engagements (UK and Ireland) 2410 "Review of Interim Financial Information Performed by the Independent Auditor of the Entity" issued by the Auditing Practices Board for use in the United Kingdom. A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with International Standards on Auditing (UK and Ireland) and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the condensed set of financial statements in the half-yearly financial report for the six months ended 30 June 2013 is not prepared, in all material respects, in accordance with International Accounting Standard 34 as adopted by the European Union and the Disclosure and Transparency Rules of the United Kingdom's Financial Conduct Authority.

These Condensed Consolidated Interim Financial Statements are prepared for Santander UK plc (the 'Company') and the Santander UK plc group (the 'Santander UK group') under the Companies Act 2006. The principal activity of the Santander UK group is the provision of an extensive range of personal financial services, and a wide range of banking and financial services to business and public sector customers.

Santander UK plc is a public limited company, incorporated in England and Wales, having a registered office in England and is the holding company of the Santander UK group as well as undertaking banking and financial services transactions as an operating company.

These Condensed Consolidated Interim Financial Statements are not a form of statutory accounts. The information for the year ended 31 December 2012 does not constitute statutory accounts as defined in section 434 of the Companies Act 2006. A copy of the statutory accounts for that financial year has been delivered to the Registrar of Companies. The auditor's report on those accounts was unqualified, did not draw attention to any matters by way of emphasis and did not contain a statement under section 498(2) or (3) of the Companies Act 2006.

The Condensed Consolidated Interim Financial Statements have been prepared in accordance with International Accounting Standard ('IAS') 34 'Interim Financial Reporting', as issued by the International Accounting Standards Board ('IASB'), including interpretations issued by the IFRS Interpretations Committee ('IFRIC') of the IASB (together 'IFRS'). The Santander UK group has also complied with its legal obligation to comply with International Financial Reporting Standards as adopted by the European Union as there are no applicable differences between the two frameworks for the periods presented. Accordingly, certain information and disclosures normally required to be included in the notes to the annual financial statements have been omitted or condensed. The Condensed Consolidated Interim Financial Statements should be read in conjunction with the Consolidated Financial Statementsof the Santander UK plc group for the year ended 31 December 2012 which were prepared in accordance with International Financial Reporting Standards ('IFRS') as issued by the IASB in addition to being consistent with IFRS as adopted for use in the European Union.

The same accounting policies, presentation and methods of computation are followed in these Condensed Consolidated Interim Financial Statements as were applied in the presentation of the Santander UK plc group's 2012 Annual Report except as described below:

Recent accounting developments

In 2013, the Santander UK group adopted the following amendments to standards which became effective for financial years beginning on 1 January 2013.

Future accounting developments

The Santander UK group has not yet adopted the following significant new or revised standards and interpretations, and amendments thereto, which have been issued but which are not yet effective for the Santander UK group:

The Condensed Consolidated Interim Financial Statements reflect all adjustments that, in the opinion of management of the Santander UK group, are necessary for a fair presentation of the results of operations for the interim period. All such adjustments to the financial information are of a normal, recurring nature. Because the results from common banking activities are so closely related and responsive to changes in market conditions, the results for any interim period are not necessarily indicative of the results that can be expected for the year.

The Directors have assessed the ability of the Santander UK group to continue as a going concern, in the light of uncertain current and anticipated economic conditions, including analysing the financial resources available to it and stress testing performance forecasts through various scenarios. The Directors confirm they are satisfied that the Santander UK group has adequate resources to continue in business for the foreseeable future. For this reason, they continue to adopt the 'going concern' basis of accounting for preparing financial statements.

CONSOLIDATION

a) Subsidiaries

The Condensed Consolidated Interim Financial Statements incorporate the financial statements of Santander UK plc and entities (including structured entities) controlled by the Company and its subsidiaries. Control is achieved where the Company has (i) power over the investee; (ii) is exposed, or has rights, to variable returns from its involvement with the investee; and (iii) has the ability to use its power to affect its returns. The Company reassesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control listed above.

Consolidation of a subsidiary begins when the Company obtains control over the subsidiary and ceases when the Company loses control of the subsidiary. Specifically, the results of a subsidiary acquired or disposed of during the year are included in the consolidated statement of profit or loss and other comprehensive income from the date the Company gains control until the date when the Company ceases to control the subsidiary. Inter-company transactions, balances and unrealised gains on transactions between Santander UK group companies are eliminated; unrealised losses are also eliminated unless the cost cannot be recovered.

The acquisition method of accounting is used to account for the acquisition of subsidiaries. The cost of an acquisition is measured at the fair value of the assets given up, shares issued or liabilities undertaken at the date of acquisition. Acquisition related costs are expensed as incurred. The excess of the cost of acquisition, as well as the fair value of any interest previously held, over the fair value of the Santander UK group's share of the identifiable net assets of the acquired subsidiary, associate or business at the date of acquisition is recorded as goodwill. When the Group loses control of a subsidiary, the profit or loss on disposal is calculated as the difference between (i) the aggregate of the fair value of the consideration received and the fair value of any retained interest and (ii) the previous carrying amount of the assets (including goodwill), less liabilities of the subsidiary and any non-controlling interests. Amounts previously recognised in other comprehensive income in relation to the subsidiary are accounted for (i.e. reclassified to profit or loss or transferred directly to retained earnings) in the same manner as would be required if the relevant assets or liabilities are disposed of. The fair value of any investment retained in the former subsidiary at the date when control is lost is regarded as the fair value on initial recognition for subsequent accounting under IAS 39 "Financial Instruments: Recognition and Measurement" or, when applicable, the costs on initial recognition of an investment in an associate or jointly controlled entity.

Transactions between entities under common control, i.e. fellow subsidiaries of Banco Santander, S.A. (the "ultimate parent") are outside the scope of IFRS 3 - "Business Combinations", and there is no other guidance for such situations under IFRS. The Santander UK group elects to account for transactions between entities under common control for cash consideration in a manner consistent with the approach under IFRS 3R, except for the continued disclosure of those IBNO provisions for a portfolio that cannot easily be allocated to individual loans, unless the transaction represents a reorganisation of entities within the Santander UK group, in which case the transaction is accounted for at its historical cost. Business combinations between entities under common control transacted for non-cash consideration are accounted for by the Santander UK group in a manner consistent with group reconstruction relief under UK GAAP (merger accounting).

b) Associates and joint ventures

Associates are entities over which the Santander UK group has significant influence and that is neither a subsidiary nor an interest in a joint venture. Significant influence is the power to participate in the financial and operating policy decisions of the investee but is not control or joint control over those policies. Unrealised gains on transactions between the Santander UK group and its associates are eliminated to the extent of the Santander UK group's interest in the associates; unrealised losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. The Santander UK group's investment in associates includes goodwill on acquisition.

Joint ventures are joint arrangements whereby the parties that have joint control of the arrangement have rights to the net assets of the joint arrangement. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require unanimous consent of the parties sharing control.

The Santander UK group's investments in associates and joint ventures are accounted for by the equity method of accounting and are initially recorded at cost and adjusted each year to reflect the Santander UK group's share of the post-acquisition results of the joint venture or associate. The share of any losses is restricted to a level that reflects an obligation to fund such losses. The Santander UK group does not hold significant investments in associates or joint ventures.

HEDGE ACCOUNTING

Santander UK plc group applies hedge accounting to represent, to the maximum possible extent permitted under accounting standards, the economic effects of its risk management strategies. Derivatives are used to hedge interest rate, exchange rate and exposures to certain indices such as retail price indices.

At the time a financial instrument is designated as a hedge (i.e., at the inception of the hedge), the Santander UK group formally documents the relationship between the hedging instrument(s) and hedged item(s), its risk management objective and strategy for undertaking the hedge. The documentation includes the identification of each hedging instrument and respective hedged item, the nature of the risk being hedged (including the benchmark interest rate being hedged in a hedge of interest rate risk) and how the hedging instrument's effectiveness in offsetting the exposure to changes in the hedged item's fair value attributable to the hedged risk is to be assessed. Accordingly, the Santander UK group formally assesses, both at the inception of the hedge and on an ongoing basis, whether the hedging derivatives have been and will be highly effective in offsetting changes in the fair value attributable to the hedged risk during the period that the hedge is designated. A hedge is normally regarded as highly effective if, at inception and throughout its life, the Santander UK group can expect, and actual results indicate, that changes in the fair value or cash flow of the hedged items are effectively offset by changes in the fair value or cash flow of the hedging instrument. If at any point it is concluded that it is no longer highly effective in achieving its documented objective, hedge accounting is discontinued.

Where derivatives are held for risk management purposes, and when transactions meet the required criteria for documentation and hedge effectiveness, the derivatives may be designated as either: (i) hedges of the change in fair value of recognised assets or liabilities or firm commitments ('fair value hedges'); (ii) hedges of the variability in highly probable future cash flows attributable to a recognised asset or liability, or a forecast transaction ('cash flow hedges'); or (iii) a hedge of a net investment in a foreign operation ('net investment hedges'). The Santander UK group applies fair value hedge accounting and cash flow hedge accounting but not hedging of a net investment in a foreign operation.

a) Fair value hedge accounting

Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recorded in the income statement, together with the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk. Where the hedged item is measured at amortised cost, the fair value changes adjust the carrying amount of the hedged asset or liability. Changes in the fair value of portfolio hedged items are presented separately in the statement of financial position and recognised in the statement of comprehensive income as gains or losses on financial assets and liabilities held for trading. If the hedge no longer meets the criteria for hedge accounting, changes in the fair value of the hedged item attributable to the hedged risk are no longer recognised in the income statement. For fair value hedges of interest rate risk, the cumulative adjustment that has been made to the carrying amount of the hedged item is amortised to the income statement using the effective interest method over the period to maturity. For portfolio hedged items, the cumulative adjustment is amortised to the income statement using the straight line method over the period to maturity.

b) Cash flow hedge accounting

The effective portion of changes in the fair value of qualifying cash flow hedges is recognised in other comprehensive income in the cash flow hedging reserve. The gain or loss relating to the ineffective portion is recognised immediately in the income statement. Amounts accumulated in equity are reclassified to the income statement in the periods in which the hedged item affects profit or loss. When a hedging instrument expires or is sold, or when a hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss existing in equity at that time remains in equity and is recognised in the income statement when the forecast transaction is ultimately recognised in the income statement. When a forecast transaction is no longer expected to occur, the cumulative gain or loss that was reported in equity is immediately transferred to the income statement.

CRITICAL ACCOUNTING POLICIES AND AREAS OF SIGNIFICANT MANAGEMENT JUDGEMENT

The preparation of the Santander UK group's Condensed Consolidated Interim Financial Statements requires management to make estimates and judgements that affect the reported amount of assets and liabilities at the date of the Condensed Consolidated Interim Financial Statements and the reported amount of income and expenses during the reporting period. Management evaluates its estimates and judgements on an ongoing basis. Management bases its estimates and judgements on historical experience and on various other factors that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

The following accounting estimates and judgements are considered important to the portrayal of the Santander UK group's financial results and financial condition because: (i) they are highly susceptible to change from period to period as assumptions are made to calculate the estimates, and (ii) any significant difference between the Santander UK group's estimated amounts and actual amounts could have a material impact on the Santander UK group's future financial results and financial condition.

In calculating each estimate, a range of outcomes was calculated based principally on management's conclusions regarding the input assumptions relative to historic experience. The actual estimates were based on what management concluded to be the most probable assumptions within the range of reasonably possible assumptions.

a) Impairment loss allowances for loans and advances

The Santander UK group estimates impairment losses for loans and advances to customers, loans and receivables securities, and loans and advances to banks as described in the accounting policy "Impairment of financial assets" on page 219 of the 2012 Annual Report. The Santander UK group's assumptions about estimated losses are based on past performance, past customer behaviour, the credit quality of recent underwritten business and general economic conditions, which are not necessarily an indication of future losses.

The net impairment loss (i.e. after recoveries) for loans and advances to customers in the Retail Banking segment recognised in the first half of 2013 was £184m (six months ended 30 June 2012: £221m), in the Corporate Banking segment was £51m (six months ended 30 June 2012: £56m) and in the Corporate Centre segment was £nil (six months ended 30 June 2012: £73m). In calculating the Retail Banking and Corporate Banking impairment loss allowances, a range of outcomes was calculated, either for each individual loan or by portfolio, based on management's conclusions regarding the estimated number of accounts that will be written off or repossessed (the 'loss propensity'), the estimated proportion of such cases that will result in a loss (the 'loss factor') and the average loss incurred (the 'loss per case') relative to historic experience.

Had management used different assumptions, a larger or smaller impairment loss allowance would have resulted that could have had a material impact on the Santander UK group's reported profit before tax. Specifically, if management's conclusions as to the loss propensity, the loss factor and the estimated loss per case were different, but within the range of what management deemed to be reasonably possible, the impairment loss for loans and advances in the Retail Banking segment could have decreased in the first half of 2013 from an actual impairment loss of £184m (six months ended 30 June 2012: £221m) by up to £31m (six months ended 30 June 2012: £51m), with a potential corresponding increase in the Santander UK group's profit before tax in the first half of 2013 of up to 7% (six months ended 30 June 2012: 7%), or increased by up to £18m (six months ended 30 June 2012: £28m), with a potential corresponding decrease in the Santander UK group's profit before tax in the first half of 2013 of up to 5% (six months ended 30 June 2012: 4%).

Similarly, the impairment loss for loans and advances in the Corporate Banking segment could have decreased in 2013 from an actual impairment loss of £51m (six months ended 30 June 2012: £56m) by up to £44m (six months ended 30 June 2012: £9m), with a potential corresponding increase in the Santander UK group's profit before tax in the first half of 2013 of up to 8% (six months ended 30 June 2012: 1%), or increased by up to £23m (six months ended 30 June 2012: £8m), with a potential corresponding decrease in the Santander UK group's profit before tax in the first half of 2013 of up to 4% (six months ended 30 June 2012: 1%).

Similarly, the impairment loss for loans and advances in the Corporate Centre segment could have decreased in the first half of 2013 from an actual impairment loss of £nil (six months ended 30 June 2012: £73m) by up to £50m (six months ended 30 June 2012: £12m), with a potential corresponding increase in the Santander UK group's profit before tax in the first half of 2013 of up to 9% (six months ended 30 June 2012: 2%), or increased by up to £25m (six months ended 30 June 2012: £11m), with a potential corresponding decrease in the Santander UK group's profit before tax in the first half of 2013 of up to 5% (six months ended 30 June 2012: 2%).

b) Valuation of financial instruments

The Santander UK group trades in a wide variety of financial instruments in the major financial markets. When estimating the value of its financial instruments, including derivatives where quoted market prices are not available, management therefore considers a range of interest rates, volatility, exchange rates, counterparty credit ratings, valuation adjustments and other similar inputs, all of which vary across maturity bands. These are chosen to best reflect the particular characteristics of each transaction.

Had management used different assumptions, a larger or smaller change in the valuation of financial instruments including derivatives where quoted market prices are not available would have resulted that could have had a material impact on the Santander UK group's reported profit before tax.

Detailed disclosures on financial instruments, including sensitivities, can be found in Note 46 of the 2012 Annual Report. Further information about sensitivities to market risk (including Value-at-Risk ('VaR')) arising from financial instrument trading activities can be found in the Risk Management Report on page 66.

c) Goodwill impairment

A goodwill impairment loss of £nil was recognised in the first half of 2013 (six months ended 30 June 2012: £nil). The carrying amount of goodwill was £1,834m at 30 June 2013 (2012: £1,834m). The Santander UK group evaluates whether the carrying value of goodwill is impaired and performs impairment testing annually or more frequently if there are impairment indicators present. Details of the Santander UK group's approach to identifying and quantifying impairment of goodwill are set out in Note 14. Assumptions about the measurement of the estimated recoverable amount of goodwill are based on management's estimates of future cash flows and growth rates of the cash-generating units. The Santander UK group's assumptions about estimated future cash flows and growth rates are based on management's view of future business prospects at the time of the assessment and are subject to a high degree of uncertainty.

Had management used different assumptions, a larger or smaller goodwill impairment loss would have resulted that could have had a material impact on the Santander UK group's reported profit before tax. Detailed disclosures on the assumptions used, including sensitivities, can be found in Note 14.

d) Provision for conduct remediation

Detailed disclosures on the provision for conduct remediation can be found in Note 21. The provision represents management's best estimate of the anticipated costs of related customer contact and/or redress, including administration expenses. However, with respect to payment protection insurance ('PPI'), there are still a number of uncertainties as to the eventual costs from any such contact and/or redress given the inherent difficulties in assessing the impact of detailed implementation of the FSA Policy Statement of 10 August 2010 for all PPI complaints, uncertainties around the ultimate emergence period for complaints, the availability of supporting evidence and the activities of claims management companies, all of which will significantly affect complaints volumes, uphold rates and redress costs. Similar uncertainty arises with respect to other products for which provision has been required in the first half of 2013.

The provision requires significant judgement by management in determining appropriate assumptions, which include the level of complaints, of those, the number that will be upheld, as well as redress costs for each of the different populations of customers identified by the Santander UK group in its analyses used to determine the best estimate of the anticipated costs of redress.

Had management used different assumptions, a larger or smaller provision release would have resulted that could have had a material impact on the Santander UK group's reported profit before tax. Specifically, if the level of PPI complaints had been one percentage point higher/(lower) than estimated for all policies written then the provision at 30 June 2013 would have increased/(decreased) by approximately £32m (2012: £32m). There are a large number of inter-dependent assumptions under-pinning the provision; this sensitivity assumes that all assumptions, other than the level of complaints, remain constant. Other factors are more observable as the provision is based on current levels with respect to uphold rates and redress costs. With respect to products for which provision was required in 2013, while similar uncertainties arise, it is too early to provide a meaningful range.

The Santander UK group will re-evaluate the assumptions underlying its analysis at each reporting date as more information becomes available. As noted above, there is inherent uncertainty in making estimates; actual results in future periods may differ from the amount provided.

e) Pensions

The Santander UK group operates a number of defined benefit pension schemes as described in Note 22 and estimates their fair values as described in the accounting policy "Pensions and other post retirement benefits" on page 213 of the 2012 Annual Report.

The defined benefit service cost recognised in the six months ended 30 June 2013 was £20m (six months ended 30 June 2012: £15m). The defined benefit pension schemes which were in a net asset position had a surplus of £203m (2012: surplus of £254m) and the defined benefit pension schemes which were in a net liability position had a deficit of £460m (2012: deficit of £305m).

Accounting for defined benefit pension schemes requires management to make assumptions, principally about mortality, but also about price inflation, discount rates, pension increases, and earnings growth. Management's assumptions are based on past experience and current economic trends, which are not necessarily an indication of future experience.

Detailed disclosures on the current year service cost and deficit, including sensitivities, can be found in Note 22.

2. SEGMENTS

The principal activity of the Santander UK group is financial services. TheSantander UK group's business is managed and reported on the basis of the following segments:

In the first half of 2013, the Company completed deals to sell its co-brand credit cards business, and the business was managed and reported as part of Corporate Centre, rather than Retail Banking as in 2012. The segmental analysis for the prior period has been adjusted to reflect the fact that reportable segments have changed.

The Santander UK group's segments are strategic business units that offer different products and services. They are managed separately because each business requires different technology and marketing strategies. The Santander UK grouphas four segments:

The Company's board of directors (the 'Board') is the chief operating decision maker for the Santander UK group. The segment information below is presented on the basis used by the Board to evaluate performance and allocate resources. The Board reviews discrete financial information for each segment of the business, including measures of operating results, assets and liabilities. The segment information reviewed by the Board is prepared on a statutory basis of accounting.

Transactions between the business segments are on normal commercial terms and conditions. The accounting policies of the segments are the same as those described in the summary of significant accounting policies. Internal charges and internal UK transfer pricing adjustments have been reflected in the performance of each business. Revenue sharing agreements are used to allocate external customer revenues to a business segment on a reasonable basis. Funds are ordinarily reallocated between segments, resulting in funding cost transfers disclosed in total trading income. Interest charged for these funds is based on the Santander UK group's cost of wholesale funding.

Interest income and interest expense have not been reported separately. The majority of the revenues from the segments presented below are interest income in nature and the Board relies primarily on net interest income to both assess the performance of the segment and to make decisions regarding allocation of segmental resources.

(1) Includes customer assets, net of impairment loss allowances.

(2) Full-time equivalents

(1) Adjusted to reflect the presentation of discontinued operations, as set out in Note 6 to the Condensed Consolidated Interim Financial Statements.

(2) Includes customer assets, net of impairment loss allowances.

(3) Full-time equivalents.

3. NET TRADING AND OTHER INCOME

"Net trading and funding of other items by the trading book" includes fair value gains/(losses) of £137m (six months ended 30 June 2012: £(57)m) on embedded derivatives bifurcated from certain equity index-linked deposits. The embedded derivatives are economically hedged internally with the equity derivatives trading desk. These internal transactions are managed as part of the overall positions of the equity derivatives trading desk, the results of which are also included in this line item, and amounted to £136m (six months ended 30 June 2012: £(58)m). As a result, the net fair value movements recognised on the equity index-linked deposits and the related economic hedges were £1m (six months ended 30 June 2012: £1m).

4. IMPAIRMENT LOSSES AND PROVISIONS

5. TAXATION CHARGE

Interim period corporation tax is accrued based on the estimated average annual effective corporation tax rate for the year of 23% (2012: 23.5%). The standard rate of UK corporation tax was 23.25% (2012: 24.5%). The standard rate of UK corporation tax was reduced from 24% to 23% with effect from 1 April 2013. Taxation for other jurisdictions is calculated at the rates prevailing in the relevant jurisdictions.

The Finance Act 2012, which provided for a reduction in the main rate of UK corporation tax to 23% effective from 1 April 2013 was enacted on 17 July 2012. The UK Government has also indicated that it intends to enact a further reduction in the main tax rate down to 21% on1 April 2014 and then to 20% on 1 April 2015. These changes in the rate were substantively enacted on 2 July 2013 after the balance sheet date and, therefore, are not included in these Condensed Consolidated Interim Financial Statements. The estimated financial statement impact of these changes is insignificant.

The tax expense differs from the theoretical amount that would arise using the UK statutory rate as follows:

Further information about deferred tax is presented in Note 16.

6. DISCONTINUED OPERATIONS

In the first half of 2013, the Company completed deals to sell its co-brand credit cards business for a cash consideration of £660m. The net assets disposed of consisted of loans to customers of £672m, at 31 December 2012 assets of £1.2bn were classified as held for sale, during 2013 these have been removed from Loans and Advances to Customers and presented within Other Assets within the Corporate Centre segment. The results, and loss on sale, of the discontinued operations were as follows:

7. DIVIDENDS

Dividends of £450m (2012: £425m) were paid on Santander UK plc's ordinary shares in issue during the period. The annual dividend of £21m on the Step-Up Callable Perpetual Reserve Capital Instruments was paid on 14 February 2013, the annual dividend of £17m on the £300m Step-up Callable Perpetual Preferred Securities, was paid on 22 March 2013, and the annual dividend of £19m on the £300m fixed/floating rate non-cumulative callable preference shares was paid on 24 May 2013.

An interim dividend of £215m was declared on 25 June 2013 on the Company's ordinary shares in issue.

8. TRADING ASSETS

(1) Comprises short-term loans of £1m (2012: £2m) and cash collateral of £2,193m (2012: £2,741m).

(2) Comprises short-term loans.

9. DERIVATIVE FINANCIAL INSTRUMENTS

Derivatives are financial instruments whose value is derived from the price of one or more underlying items such as equities, equity indices, interest rates, foreign exchange rates, property indices, commodities and credit spreads. Derivatives enable users to manage exposure to credit or market risks. The Santander UK group sells derivatives to its customers and uses derivatives to manage its own exposure to credit and market risks. Details of the Santander UK group's uses of derivatives are set out in Note 15 of the 2012 Annual Report.

Included in the above balances are amounts owed to the Santander UK group by Banco Santander, S.A. and other subsidiaries of Banco Santander, S.A. outside the Santander UK group of £1,726m (2012: £2,028m) and £148m (2012: £169m) respectively and amounts owed by the Santander UK group to Banco Santander, S.A. and other subsidiaries of Banco Santander, S.A. outside the Santander UK group of £1,600m (2012: £1,916m) and £181m (2012: £117m). The net exposures after collateral to the ultimate parent undertaking and fellow subsidiaries at 30 June 2013 amounted to £84m (2012: £138m) and £7m (2012: £7m), respectively.

Net gains or losses arising from fair value and cash flow hedges included in net trading and other income

The Santander UK group hedges its exposures to various risks, including interest rate risk and foreign currency risk, in connection with certain mortgage assets, covered bond issuances, and subordinated and senior debt securities in issue. The gains/(losses) arising on these assets and liabilities are presented in the table above on a combined basis.

In addition, in the ordinary course of business, the Santander UK group entered into long-term interest rate contracts as economic hedges with five investment vehicles whose underlying assets comprise debt securities, bank loans and energy and infrastructure financings. Although the vehicles themselves are not externally rated, the counterparty exposure ranks super-senior to the most senior notes issued by the vehicles and these notes are rated AAA or AA. The total mark-to-market exposure at 30 June 2013 was £42m (2012: £50m). These long-term interest rate hedging contracts are included within "derivatives held for trading - interest rate contracts" shown above.

Hedged cash flows

The following tables show when the Santander UK group's hedged cash flows are expected to occur and when they will affect income for designated cash flow hedges.

There were no hedging instruments designated as cash flow hedges during the year ended 31 December 2012.

There were no transactions for which cash flow hedge accounting had to be ceased during the six months ended 30 June 2013 as a result of the highly probable cash flows no longer being expected to occur.

Gains and losses transferred from the cash flow hedging reserve in the current period to net interest income was a £14m gain (year ended 31 December 2012: £nil) and net trading and other income was a £356m gain (year ended 31 December 2012: £nil).

10. FINANCIAL ASSETS DESIGNATED AT FAIR VALUE

Financial assets are designated at fair value through profit or loss where this results in more relevant information because it significantly reduces a measurement inconsistency that would otherwise arise from measuring the assets or liabilities or recognising gains or losses on them on a different basis, or where the assets are managed and their performance evaluated on a fair value basis, or where a contract contains one or more embedded derivatives which would otherwise require bifurcation and separate recognition as derivatives.

Included in the above balances are amounts owed to the Santander UK group by Banco Santander, S.A. and other subsidiaries of Banco Santander, S.A. outside the Santander UK group of £nil (2012: £nil) and £56m (2012: £47m) respectively.

The maximum exposure to credit risk on loans and advances designated as held at fair value through profit or loss at the balance sheet date was £2,272m (2012: £3,248m). The maximum exposure was mitigated by a charge over the residential properties in respect of lending to housing associations amounting to £2,426m (2012: £3,377m) for the Santander UK group.

The net gain during the period attributable to changes in credit risk for loans and advances designated at fair value was £7m (six months ended 30 June 2012: net loss of £19m). The cumulative net loss attributable to changes in credit risk for loans and advances designated at fair value at 30 June 2013 was £349m (2012: cumulative net loss of £356m).

13. AVAILABLE-FOR-SALE SECURITIES

14. INTANGIBLE ASSETS

a) Goodwill

Impairment of goodwill

During the period, no impairment of goodwill was recognised (six months ended 30 June 2012: £nil). Impairment testing in respect of goodwill allocated to each cash-generating unit is performed annually or more frequently if there are impairment indicators present. For the purpose of impairment testing, the cash-generating units are based on customer groups within the relevant business divisions.

Based on the conditions at the balance sheet date, management determined that a reasonably possible change in any of the key assumptions described above would not cause an impairment to be recognised in respect of goodwill arising on theSantander UK group's business combinations.

The following cash-generating units include in their carrying values goodwill that comprises the goodwill reported by the Santander UK group. The cash-generating units do not carry on their balance sheets any other intangible assets with indefinite useful lives.
