Disclosure of credit risk exposure [abstract]
Risk Management and Principal Risks	Credit risk management (audited) The risk of loss to the Barclays Bank Group from the failure of clients, customers or counterparties, including sovereigns, to fully honour their obligations to the Barclays Bank Group, including the whole and timely payment of principal, interest, collateral and other receivables. Overview The credit risk that the Barclays Bank Group faces arises from wholesale and retail loans and advances together with the counterparty credit risk arising from derivative contracts with clients ' trading activities, including: debt securities, settlement balances with market counterparties, FVOCI (fair value through other comprehensive income) assets and reverse repurchase loans. Credit risk management objectives are to: ▪ maintain a framework of controls to oversee credit risk ▪ identify, assess and measure credit risk clearly and accurately across the Barclays Bank Group and within each separate business, from the level of individual facilities up to the total portfolio ▪ control and plan credit risk taking in line with external stakeholder expectations, including risk return objectives, and avoiding undesirable concentrations ▪ monitor credit risk and adherence to agreed controls. Organisation, roles and responsibilities The first line of defence has primary responsibility for managing credit risk within the risk appetite and limits set by the Risk function, supported by a defined set of policies, standards and controls. In the Barclays Bank Group, business risk committees (attended by the first line) monitor and review the credit risk profile of each business unit where the most material issues are escalated to the Retail Credit Risk Management Committee, Wholesale Credit Risk Management Committee and the Barclays Group Risk Committee. Wholesale and retail portfolios are managed separately to reflect the differing nature of the assets; wholesale balances tend to be larger and are managed on an individual basis, while retail balances are greater in number but lesser in value and are, therefore, managed in aggregated segments. The responsibilities of the credit risk management teams in the businesses, the sanctioning team and other shared services include: sanctioning new credit agreements (principally wholesale); setting strategies for approval of transactions (principally retail); setting risk appetite; monitoring risk against limits and other parameters; setting recession readiness frameworks to protect portfolios in the event of economic stress, maintaining robust processes, data gathering, quality, storage and reporting methods for effective credit risk management; performing effective turnaround and workout scenarios for wholesale portfolios via dedicated restructuring and recoveries teams; maintaining robust collections and recovery processes/units for retail portfolios. The credit risk management teams in the Barclays Bank Group are accountable to the Barclays Bank PLC CRO, who reports to the Barclays Group CRO. For wholesale portfolios, credit risk managers are organised in sanctioning teams by geography, industry and/or product. In wholesale portfolios, credit risk approval is undertaken by experienced credit risk professionals operating within a clearly defined delegated authority framework, with only the most senior credit officers assigned the higher levels of delegated authority. The largest credit exposures, which are outside the Risk Sanctioning Unit or Risk Distribution Committee authority, require the support of the Barclays Bank PLC Senior Credit Officers. For exposures in excess of the Barclays Bank PLC Senior Credit Officers’ authority, approval by the Barclays Group Senior Credit Officer/Barclays PLC Board Risk Committee is also required. The Barclays Group Credit Risk Committee, attended by the Barclays Bank PLC Senior Credit Officers, provides a formal mechanism for the Barclays Group Senior Credit Officer to exercise the highest level of credit authority over the most material Barclays Group single name exposures. Credit risk mitigation The Barclays Bank Group employs a range of techniques and strategies to actively mitigate credit risks. These can broadly be divided into three types: ▪ netting and set-off ▪ collateral ▪ risk transfer. Netting and set-off Credit risk exposures can be reduced by applying netting and set-off. For derivative transactions, the Barclays Bank Group’s normal practice is to enter into standard master agreements with counterparties (e.g. ISDAs). These master agreements typically allow for netting of credit risk exposure to a counterparty resulting from derivative transactions against the obligations to the counterparty in the event of default, and so produce a lower net credit exposure. These agreements may also reduce settlement exposure (e.g. for foreign exchange transactions) by allowing payments on the same day in the same currency to be set-off against one another. Collateral The Barclays Bank Group has the ability to call on collateral in the event of default of the counterparty, comprising: ▪ home loans: a fixed charge over residential property in the form of houses, flats and other dwellings. ▪ wholesale lending: a fixed charge over commercial property and other physical assets, in various forms. ▪ other retail lending: includes charges over other physical assets; second lien charges over residential property and finance lease receivables. ▪ derivatives: the Barclays Bank Group also often seeks to enter into a margin agreement (e.g. Credit Support Annex) with counterparties with which the Barclays Bank Group has master netting agreements in place. These annexes to master agreements provide a mechanism for further reducing credit risk, whereby collateral (margin) is posted on a regular basis (typically daily) to collateralise the mark to market exposure of a derivative portfolio measured on a net basis. ▪ reverse repurchase agreements: collateral typically comprises highly liquid securities which have been legally transferred to the Barclays Bank Group subject to an agreement to return them for a fixed price. ▪ financial guarantees and similar off-balance sheet commitments: cash collateral may be held against these arrangements. Risk transfer A range of instruments including guarantees, credit insurance, credit derivatives and securitisation can be used to transfer credit risk from one counterparty to another. These mitigate credit risk in three main ways: ▪ if the risk is transferred to a counterparty which is more creditworthy than the original counterparty, then overall credit risk is reduced. ▪ where recourse to the first counterparty remains, both counterparties must default before a loss materialises. This is less likely than the default of either counterparty individually, so credit risk is reduced . ▪ first loss exposures across pools of credit risk can be hedged via synthetic securitisation structures, typically via CLN issuance. As these are fully funded upfront, they provide for a direct reduction in credit risk exposure on referenced pools. Market risk management (audited) The risk of loss arising from potential adverse changes in the value of the Barclays Bank Group’s assets and liabilities from fluctuation in market variables including, but not limited to, interest rates, foreign exchange, equity prices, commodity prices, credit spreads, implied volatilities and asset correlations. Overview Market risk arises primarily as a result of client facilitation in wholesale markets, involving market making activities, risk management solutions and execution of syndications. Upon execution of a trade with a client, the Barclays Bank Group will look to hedge against the risk of the trade moving in an adverse direction. Mismatches between client transactions and hedges result in market risk due to changes in asset prices, volatility or correlations. Organisation, roles and responsibilities Market risk in the businesses resides primarily in IB and Treasury. These businesses have the mandate to assume market risk. The front office and Treasury trading desks are responsible for managing market risk on a day-to-day basis, where they are required to understand and adhere to all limits applicable to their businesses. The Market Risk team supports the trading desks with the day-to-day limit management of market risk exposures through governance processes which are outlined in supporting market risk policies and standards. Market risk oversight and challenge is provided by business committees and Barclays Group committees, including the Market Risk Committee (MRC). The objectives of market risk management are to: ▪ identify, understand and control market risk by robust measurement, limit setting, reporting and oversight ▪ facilitate business growth within a controlled and transparent risk management framework ▪ control market risk in the businesses according to the allocated appetite. To meet the above objectives, a governance structure is in place to manage these risks consistent with the ERMF. The Barclays Bank PLC Board Risk Committee recommends market risk appetite to the Barclays Bank PLC Board for their approval, within the parameters set by the Barclays PLC Board. The Market Risk Committee (MRC) reviews and makes recommendations concerning the Barclays Group-wide market risk profile. This includes overseeing the operation of the Market Risk Framework and associated policies and standards, monitoring market and regulatory changes, and reviewing limit utilisation levels. The committee is chaired by the Market Risk Principal Risk Lead and attendees include the business heads of market risk and business aligned market risk managers. In addition to MRC, the Investment Bank Risk Committee (IBRC) is the main forum in which market risk exposures are discussed and reviewed with senior business heads. The Committee is chaired by the CRO of the Investment Bank and meets weekly, covering current market events, notable market risk exposures, and key risk topics. New business initiatives are generally socialised at IBRC before any changes to risk appetite or associated limits are considered in other governance committees. Management value at risk (VaR) VaR is an estimate of the potential loss arising from unfavourable market movements if the current positions were to be held unchanged for one business day. For internal market risk management purposes, a historical simulation methodology with a one-year equally weighted historical period, at the 95% confidence level is used for all trading books and some banking books. Limits are applied at the total level as well as by risk factor type, which are then cascaded down to particular trading desks and businesses by the market risk management function. See pages 117 to 118 for a review of management VaR. Treasury and capital risk management This comprises: Liquidity risk: The risk that the Barclays Bank Group is unable to meet its contractual or contingent obligations or that it does not have the appropriate amount, tenor and composition of funding and liquidity to support its assets. Capital risk: The risk that the Barclays Bank Group has an insufficient level or composition of capital to support its normal business activities and to meet its regulatory capital requirements under normal operating environments and stressed conditions (both actual and as defined for internal planning or regulatory testing purposes). This also includes the risk from the Barclays Bank Group’s pension plans. Interest rate risk in the banking book: The risk that the Barclays Bank Group is exposed to capital or income volatility because of a mismatch between the interest rate exposures of its (non-traded) assets and liabilities. This also includes credit spread risk in the banking book, the risk that the Barclays Bank Group is exposed to capital or income volatility because of changes in credit spreads on its (non- traded) assets and liabilities The Barclays Bank PLC Treasury function manages treasury and capital risk exposure on a day-to-day basis, with the Barclays Bank PLC Treasury Committee together with the Barclays Group Treasury Committee acting as the principal management bodies for the Barclays Bank Group. The Treasury and Capital Risk function is responsible for oversight and provides insight into key capital, liquidity, interest rate risk in the banking book (IRRBB) and pension risk management activities. The assessment and management of the Barclays Bank Group's capital and liquidity position and IRRBB and pension risk requires the use of judgement, assumptions and estimates. Please see the description of material existing and emerging risks beginning on page 47 of this Annual Report for further details on such judgements, assumptions and estimates, including the potential risks involved. Liquidity risk management (audited) Overview The efficient management of liquidity is essential to Barclays Bank PLC in order to retain the confidence of the financial markets and maintain the sustainability of the business. Treasury and Capital Risk have created a framework to manage all liquidity risk exposures under both normal and stressed conditions. The framework is designed to maintain liquidity resources that are sufficient in amount, quality and funding tenor profile to remain within the liquidity limits set by the Barclays Bank PLC Board. The Board sets liquidity limits on both internal and regulatory liquidity metrics. Organisation, roles and responsibilities Treasury has the primary responsibility for managing liquidity risk within the set risk appetite. Both Risk and Treasury contribute to the production of the Internal Liquidity Adequacy Assessment Process (ILAAP). The Treasury and Capital Risk function is responsible for the management and governance of the liquidity risk mandate, as defined by the Barclays Bank PLC Board. The framework established by Treasury and Capital Risk is designed to deliver the appropriate term and structure of funding, consistent with the risk appetite set by the Barclays Bank PLC Board. The control framework incorporates a range of ongoing business management tools to monitor and stress test Barclays Bank PLC's balance sheet and recovery plan, including limit setting. Limit setting and transfer pricing are tools that are designed to control the level of liquidity risk taken and drive the appropriate mix of funds. Adherence to limits reduces the likelihood that a liquidity stress event could lead to an inability to meet the Barclays Bank Group’s obligations as they fall due. The Barclays Bank PLC Board approves the Barclays Bank PLC funding plan, internal stress tests, regulatory stress tests, recovery plan and liquidity risk qualitative statement that supports risk appetite. Barclays Bank PLC’s Treasury Committee is responsible for monitoring and managing liquidity risk in line with Barclays Bank PLC’s funding management objectives, funding plan and risk appetite. The Barclays Group Treasury and Capital Risk Committee monitors and reviews the liquidity risk profile and control environment, providing second line oversight of the management of liquidity risk. The Barclays Bank PLC Board Risk Committee reviews the risk profile, liquidity risk qualitative statement, and Board-approved liquidity limits at least annually and the impact of stress scenarios on Barclays Bank PLC’s funding plan/ forecast in order to agree risk appetite in line with Barclays Bank PLC’s projected funding abilities. Capital risk management (audited) Overview Capital risk is managed through ongoing monitoring and management of the capital and leverage position, regular stress testing and a robust capital governance framework. The objectives of the framework are to maintain adequate capital for the Barclays Bank Group and its legal entities to withstand the impact of the risks that may arise under normal and stressed conditions, and maintain adequate capital to cover current and forecast business needs and associated risks to provide a viable and sustainable business offering. The Barclays Bank Group aims to prudently manage its overall leverage position (including risk of excessive leverage) by utilising plausible stress scenarios, reviewing and deploying management actions in response to deteriorating economic and commercial positions. In order to manage contingent leverage risk, the Barclays Bank Group considers the context from which the business consumption arises, the impact of client utilisation on leverage and the available actions to manage. Organisation, roles and responsibilities Treasury has the primary responsibility for managing and monitoring capital adequacy. The Barclays Bank Group Treasury and Capital Risk function provides oversight of capital risk. Production of the Barclays Bank PLC Internal Capital Adequacy Assessment Process (ICAAP) is the responsibility of Treasury. Capital risk management is underpinned by a control framework and policy. The capital management strategy, outlined in the relevant legal entity capital plans, is developed in alignment with the control framework and policy for capital risk, and is implemented consistently in order to deliver on the Barclays Bank Group’s objectives, which are aligned to those of the Barclays Group. The Barclays Bank PLC Board approves the Barclays Bank PLC capital plan, internal stress tests and results of regulatory stress tests and those of the relevant Barclays Bank Group entities. The Barclays PLC Board also approves the Barclays Group recovery plan which takes into account management actions identified at the Barclays Bank Group level. The Barclays Bank PLC Treasury Committee and the Barclays Group Treasury Committee are responsible for monitoring and managing capital risk in line with Barclays Bank Group’s capital management objectives, capital plan and risk frameworks. The Treasury and Capital Risk Committee (TCRC) monitors and reviews the capital risk profile and control environment, providing second line oversight of the management of capital risk. For the relevant Barclays Bank Group subsidiaries, local management assures compliance with an entity’s minimum regulatory capital requirements by reporting to local Asset and Liability Committees (or equivalents) with oversight by the Barclays Bank PLC Treasury Committee and the Barclays Group Treasury Committee, as required. In 2024 , Barclays complied with all regulatory minimum capital requirements. Contingent leverage risk is managed by; i) setting comprehensive leverage (and RWA) targets for each business as part of the Treasury capital management process, taking into account adherence to early warning indicators and maintain a healthy leverage ratio, and; ii) Monitoring execution of actions taken to course-correct as necessary. The Barclays Bank Group maintains a number of defined benefit pension schemes for past and current employees. The ability of schemes to meet pension payments is achieved with investments and contributions. Pension risk arises because the market value of pension fund assets might decline; investment returns might reduce; or the estimated value of pension liabilities might increase. The Barclays Bank Group monitors the pension risks arising from its defined benefit pension schemes and works with the relevant pension fund’s trustees to address shortfalls. In these circumstances the Barclays Bank Group could be required or might choose to make extra contributions to the pension fund. The Barclays Bank Group’s main defined benefit scheme was closed to new entrants in 2012. Interest rate risk in the banking book management (IRRBB) Overview Interest rate risk in the banking book is driven by counterparties deposit taking and lending activities, investments in the liquid asset portfolio and funding activities. As per the Barclays Bank Group’s policy to remain within the defined risk appetite, hedging strategies are executed to mitigate the various IRRBB risks that result from these activities. However, the Barclays Bank Group remains susceptible to interest rate risk and other non-traded market risks from the following key sources: ▪ Interest rate and repricing risk: the risk that net interest income could be adversely impacted by a change in interest rates, differences in the timing of interest rate changes between assets and liabilities, and other constraints on interest rate changes as per product terms and conditions. ▪ Counterparty behavioural risk: the risk that net interest income could be adversely impacted by the discretion that counterparties may have in respect of being able to vary from their contractual obligations with the Barclays Bank Group. This risk is often referred to by industry regulators as ‘embedded option risk’. ▪ Investment risks in the liquid asset portfolio: the risk that the fair value of assets held in the liquid asset portfolio and associated risk management portfolios could be adversely impacted by market volatility, creating volatility in capital directly. Organisation, roles and responsibilities The Barclays Bank PLC Treasury Committee and the Barclays Group Treasury Committee are responsible for monitoring and managing IRRBB risk in line with the Barclays Bank Group’s management objectives and risk frameworks. The BRC and Treasury and Capital Risk Committee monitors and reviews the IRRBB risk profile and control environment, providing second line oversight of the management of IRRBB. The BRC reviews the interest rate risk profile, including review of the risk appetite at least annually and the impact of stress scenarios on the interest rate risk of the Barclays Bank PLC’s banking books. In addition, the Barclays Bank Group’s IRRBB policy sets out the processes and key controls required to identify all IRRBB risks arising from banking book operations, to monitor the risk exposures via a set of metrics with a frequency in line with the risk management horizon, and to manage these risks within agreed risk appetite and limits.

Disclosure of objectives, policies and processes for managing capital [abstract]
Material accounting policies	Material accounting policies 1. Reporting entity Barclays Bank PLC is a public company limited by shares registered in England und er company number 1026167, having its registered office at 1 Churchill Place, London, E14 5HP . These financial statements are prepared for Barclays Bank PLC and its subsidiaries (the Barclays Bank Group) under Section 399 of the Companies Act 2006. The Barclays Bank Group is a major global financial services provider engaged in credit cards, wholesale banking, investment banking, wealth management and investment management services. In addition, separate financial statements have been presented for the holding company. 2. Compliance with International Financial Reporting Standards The consolidated financial statements of the Barclays Bank Group, and the separate financial statements of Barclays Bank PLC, have been prepared in accordance with UK-adopted international accounting standards. The consolidated financial statements of the Barclays Bank Group, and the separate financial statements of Barclays Bank PLC, have also been prepared in accordance with (1) International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB), including interpretations issued by the IFRS Interpretations Committee, as there are no applicable differences from IFRS as issued by the IASB for the periods presented; and (2) IFRS adopted pursuant to Regulation (EC) No. 1606/2002 as it applies in the European Union (“IFRS as adopted by the EU”). There are currently no differences between UK-adopted international accounting standards and IFRS as adopted by the EU and therefore no reconciliation of variances is provided. The principal accounting policies applied in the preparation of the consolidated and separate financial statements are set out below, and in the relevant notes to the financial statements. These policies have been consistently applied, with the exception of Classification of Liabilities as Current or Non-current (Amendments to IAS 1), which was effective from 1 January 2024 and applies retrospectively. 3. Basis of preparation The consolidated and separate financial statements have been prepared under the historical cost convention modified to include the fair valuation of investment property, and particular financial instruments, to the extent required or permitted under IFRS as set out in the relevant accounting policies. The financial statements are stated in millions of Pounds Sterling (£m), the functional currency of Barclays Bank PLC. The financial statements have been prepared on a going concern basis, in accordance with the Companies Act 2006 as applicable to companies using IFRS. The financial statements are prepared on a going concern basis as the Board is satisfied that the Barclays Bank Group and parent company have the resources to continue in business for a period of at least 12 months from approval of the financial statements. In making this assessment, the Board has considered a wide range of information relating to present and future conditions and has reviewed a working capital report (WCR). The WCR is used by the Board to assess the future performance of the Barclays Bank Group and whether it has the resources in place that are required to meet its ongoing regulatory requirements. The WCR assessment is based upon business plans which contain future forecasts of profitability taken from the Barclays Bank Group’s medium term plan as well as projections of regulatory capital requirements and business funding needs. The WCR also includes an assessment of the impact of internally generated stress testing scenarios on the liquidity and capital requirement forecasts. The stress tests used were based upon an assessment of reasonably possible downside economic scenarios that the Barclays Bank Group could experience. The WCR showed that the Barclays Bank Group had sufficient capital and liquidity in place to support its future business requirements and remained above its regulatory minimum requirements in the stress scenarios. Accordingly, the Board concluded that there was a reasonable expectation that the Barclays Bank Group has adequate resources to continue as a going concern for a period of at least 12 months from the date of approval of the financial statements. 4. Accounting policies The Barclays Bank Group prepares financial statements in accordance with IFRS. The Barclays Bank Group’s material accounting policies relating to specific financial statement items, together with a description of the accounting estimates and judgements that were critical to preparing those items, are set out under the relevant notes. Accounting policies that affect the financial statements as a whole are set out below. (i) Consolidation The consolidated financial statements combine the financial statements of Barclays Bank PLC and all its subsidiaries. Subsidiaries are entities over which Barclays Bank PLC has control. The Barclays Bank Group has control over another entity when the Barclays Bank Group has all of the following: 1) power over the relevant activities of the investee, for example through voting or other rights; 2) exposure to, or rights to, variable returns from its involvement with the investee; and 3) the ability to affect those returns through its power over the investee. As the consolidated financial statements include partnerships where the Barclays Bank Group member is a partner, advantage has been taken of the exemption under Regulation 7 of the Partnership (Accounts) Regulations 2008 with regard to preparing and filing of individual partnership financial statements. Details of the principal subsidiaries are given in Note 31. (ii) Foreign currency translation Transactions in foreign currencies are translated into Sterling at the rate ruling on the date of the transaction. Foreign currency monetary balances are translated into Sterling at the period end exchange rates. Exchange gains and losses on such balances are taken to the income statement. The Barclays Bank Group’s foreign operations (including subsidiaries, joint ventures, associates and branches) based mainly outside the UK may have different functional currencies. The functional currency of an operation is the currency of the main economy to which it is exposed. Prior to consolidation (or equity accounting) the assets and liabilities of non-Sterling operations are translated at the period end exchange rate and items of income, expense and other comprehensive income are translated into Sterling at the rate on the date of the transactions. Exchange differences arising on the translation of foreign operations are included in currency translation reserves within equity. These are transferred to the income statement when the Barclays Bank Group disposes of the entire interest in a foreign operation, when partial disposal results in the loss of control of an interest in a subsidiary, when an investment previously accounted for using the equity method is accounted for as a financial asset, or on the disposal of a foreign operation within a branch. (iii) Financial assets and liabilities Recognition The Barclays Bank Group recognises financial assets and liabilities when it becomes a party to the terms of the contract. Trade date or settlement date accounting is applied depending on the classification of the financial asset. Classification and measurement Financial assets are classified on the basis of two criteria: i) the business model within which financial assets are managed; and ii) their contractual cash flow characteristics (whether the cash flows represent ‘solely payments of principal and interest’ (SPPI)). The Barclays Bank Group assesses the business model criteria at a portfolio level. Information that is considered in determining the applicable business model includes (i) policies and objectives for the relevant portfolio, (ii) how the performance and risks of the portfolio are managed, evaluated and reported to management, and (iii) the frequency, volume and timing of sales in prior periods, sales expectation for future periods, and the reasons for such sales. The contractual cash flow characteristics of financial assets are assessed with reference to whether the cash flows represent SPPI. Terms that could change the contractual cash flows so that it would not meet the condition for SPPI are considered, including: (i) contingent and leverage features, (ii) non-recourse arrangements, (iii) features that could modify the time value of money, and (iv) Social, Environmental and Sustainability-linked features. Terms with de-minimis impact do not preclude cash flows from representing SPPI. The accounting policy for each type of financial asset or liability is included within the relevant note for the item. The Barclays Bank Group’s policies for determining the fair values of the assets and liabilities are set out in Note 16. Derecognition The Barclays Bank Group derecognises a financial asset, or a portion of a financial asset, from its balance sheet where (i) the contractual rights to cash flows from the asset have expired, or (ii) the contractual rights to the cash flows from the asset have been transferred (usually by sale) and with them either (a) substantially all the risks and rewards of the asset have been transferred, or (b) where neither substantially all the risks and rewards have been transferred or retained, where control over the asset has been lost. Financial liabilities are de-recognised when the liability has been settled, has expired or has been extinguished. An exchange of an existing financial liability for a new liability with the same lender on substantially different terms – generally a difference of 10% or more in the present value of the cash flows or a substantive qualitative amendment – is accounted for as an extinguishment of the original financial liability and the recognition of a new financial liability. It may not be obvious whether substantially all of the risks and rewards of a transferred asset, or portion of an asset, have been transferred. It is often necessary to perform a quantitative analysis that compares the Barclays Bank Group's exposure to variability in asset cash flows before the transfer with its retained exposure after the transfer. A cash flow analysis of this nature may require judgement. In particular, it is necessary to estimate the asset’s expected future cash flows as well as potential variability around this expectation. The method of estimating expected future cash flows depends on the nature of the asset, with market and market-implied data used to the greatest extent possible. The potential variability around this expectation is typically determined by stressing underlying parameters to create reasonable alternative upside and downside scenarios. Probabilities are then assigned to each scenario. Stressed parameters may include default rates, loss severity, or prepayment rates. Accounting for reverse repurchase and repurchase agreements including other similar lending and borrowing Reverse repurchase agreements (and stock borrowing or similar transactions) are a form of secured lending whereby the Barclays Bank Group provides a loan or cash collateral in exchange for the transfer of collateral, generally in the form of marketable securities subject to an agreement to transfer the securities back at a fixed price in the future. Repurchase agreements are where the Barclays Bank Group obtains such loans or cash collateral, in exchange for the transfer of collateral. The Barclays Bank Group purchases (a reverse repurchase agreement) or borrows securities subject to a commitment to resell or return them. The securities are not included in the balance sheet as the Barclays Bank Group does not acquire the risks and rewards of ownership. Consideration paid (or cash collateral provided) is accounted for as a loan asset at amortised cost, unless it is designated or mandatorily at fair value through profit and loss. The Barclays Bank Group may also sell (a repurchase agreement) or lend securities subject to a commitment to repurchase or redeem them. The securities are retained on the balance sheet as the Barclays Bank Group retains substantially all the risks and rewards of ownership. Consideration received (or cash collateral provided) is accounted for as a financial liability at amortised cost, unless it is designated at fair value through profit and loss. (iv) Issued debt and equity instruments Issued financial instruments or their components are classified as liabilities if the contractual arrangement results in the Barclays Bank Group having an obligation to either deliver cash or another financial asset, or a variable number of equity shares, to the holder of the instrument. If this is not the case, the instrument is generally an equity instrument and the proceeds included in equity, net of transaction costs. Dividends and other returns to equity holders are recognised when paid or declared by the members at the Annual General Meeting and treated as a deduction from equity. Where issued financial instruments contain both liability and equity components, these are accounted for separately. The fair value of the debt is estimated first and the balance of the proceeds is included within equity. (v) Cash flow statement Cash comprises cash on hand and balances at central banks. Cash equivalents comprise loans and advances to banks, cash collateral balances with central banks related to payment schemes and treasury and other eligible bills, all with original maturities of three months or less. Investments in debt securities at amortised cost are deemed to be investing activities for the purposes of the cash flow statement, except those instruments considered to be cash equivalents . 5. New and amended standards and interpretations The accounting policies adopted have been consistently applied, with the exception of the following: Classification of Liabilities as Current or Non-current (Amendments to IAS 1) In January 2020 the IASB issued amendments to IAS 1 to clarify the presentation of liabilities in the balance sheet, with an effective date that was subsequently deferred to 1 January 2024. The amendments clarify that a liability should be classified as non-current only if the entity has the right to defer settlement of the liability for at least 12 months after the reporting period, and that (i) the right to defer settlement must exist at the end of the reporting period and (ii) management’s intentions or expectations about whether it will exercise its right to defer settlement does not affect the classification. Further clarifications include how lending conditions affect classification and classification of liabilities the entity will or may settle by issuing its own equity instruments. In October 2022, the IASB also issued further amendments to IAS 1 to improve the information an entity provides when its right to defer settlement of a liability for at least 12 months is subject to compliance with covenants, and to respond to stakeholders’ concerns about the classification of such a liability as current or non-current. The impact to the Barclays Bank Group from these amendments is not considered to be material . Future accounting developments The following accounting standards have been issued by the IASB but are not yet effective: Amendment to IFRS 9 and IFRS 7 - Classification and Measurement of Financial Instruments In May 2024, the IASB issued targeted amendments to IFRS 9 to address feedback received from stakeholders following a post- implementation review. The amendments include: • additional guidance to clarify when certain financial assets may be compliant with SPPI requirements, including instruments with contingent features (e.g. ESG-linked financing), as well as contractually-linked instruments and non-recourse financing. • clarifying the derecognition requirements for financial assets and financial liabilities, including establishing a new accounting policy choice for derecognition of a financial liability when a payment is initiated by the reporting entity using an electronic payment system provided specified criteria is met. The amendments are effective from 1 January 2026, but are not yet endorsed for use in the UK. The Barclays Bank Group is currently assessing the impact of these amendments. IFRS 18 Presentation and Disclosure in Financial Statements In August 2024, the IASB issued a new IFRS Accounting Standard to replace IAS 1 Presentation of Financial Statements. The new standard creates detailed requirements for the classification and aggregation of income and expenses in the income statement, and disclosure requirements for management-defined performance measures. The new standard is effective from 1 January 2027, but has not yet been endorsed for use in the UK. The Barclays Bank Group is currently assessing the impact of these amendments. Amendments to IAS 21 - Lack of Exchangeability In August 2023, the IASB issued amendments to IAS 21 to define when a currency is exchangeable into another currency and, when it is not, to determine the exchange rate to use. The amendments are effective from 1 January 2025, however the impact to the Barclays Bank Group is not expected to be material . 6. Critical accounting estimates and judgements The preparation of financial statements in accordance with IFRS requires the use of estimates. It also requires management to exercise judgement in applying the accounting policies. The key areas involving a higher degree of judgement or complexity or areas where assumptions are significant to the consolidated and individual financial statements are highlighted under the relevant note. Judgements Estimates Further information Credit impairment charges Identification and application of management adjustments in response to circumstances outside the scope of the model. Estimates include modelling assumptions such as estimating forward-looking modelled parameters (PD, EAD & LGD), and a range of unbiased future economic scenarios and scenario weightings. on page 173 Tax Recognition of deferred tax assets and determination of provisions for uncertain tax positions. Measurement of deferred tax balances and the level of provisioning for uncertain tax positions include forward- looking assumptions and estimates. on page 177 Fair value of financial instruments Classification of financial instruments with significant unobservable inputs as Level 3. Valuation of Level 3 assets and liabilities are typically determined by referencing observable inputs, historical data, or employing other analytical techniques. on page 193 Pensions and post-retirement benefit obligations - Valuation of defined benefit scheme obligations includes assumptions on post-retirement mortality, discount rates and inflation. on page 226 Provisions including conduct and legal, competition and regulatory matters Determination as to whether a present obligation exists. Estimation uncertainty in the probability, timing, nature and quantum of outflows. on page 212 7. Other disclosures To improve transparency and ease of reference, by concentrating related information in one place, certain disclosures required under IFRS have been included within the Risk review section as follows: ▪ Credit risk on pages 66 to 67 and on pages 79 to 115 ▪ Market risk on page 67 and on pages 117 to 118 ▪ Treasury and capital risk – capital on page 68 to 69 and on page 126 ▪ Treasury and capital risk – liquidity on pages 68 to 69 and on pages 120 to 131 These disclosures are covered by the Audit opinion (included on pages 150 to 152 ) where referenced as audited.

Analysis of income and expense [abstract]
Net interest income	Net interest income Accounting for interest income and expenses Interest income on loans and advances at amortised cost, financial assets at fair value through other comprehensive income, interest expense on financial liabilities held at amortised cost are calculated using the effective interest method which allocates interest, and direct and incremental fees and costs, over the expected lives of the assets and liabilities. The effective interest method requires the Barclays Bank Group to estimate future cash flows, in some cases based on its experience of customers’ behaviour, considering all contractual terms of the financial instrument, as well as the expected lives of the assets and liabilities. The Barclays Bank Group incurs certain costs to originate credit card balances with the most significant being co-brand partner fees. To the extent these costs are attributed to customers that continuously carry an outstanding balance (revolvers) and incremental to the origination of credit card balances, they are capitalised and subsequently included within the calculation of the effective interest rate. They are amortised to interest income over the period of expected repayment of the originated balance. Costs attributed to customers that settle their outstanding balances each period (transactors) are deferred on the balance sheet as a cost of obtaining a contract and amortised to fee and commission expense over the life of the customer relationship (refer to Note 4). There are no other individual estimates involved in the calculation of effective interest rates that are material to the results or financial position. 2024 2023 2022 £m £m £m Cash and balances at central banks 9,567 8,384 2,097 Debt securities at amortised cost 1,737 1,819 1,035 Loans and advances at amortised cost 9,508 7,854 6,419 Fair value through other comprehensive income 2,335 3,808 1,493 Cash collateral 2,026 1,987 405 Other 1 607 409 330 Interest and similar income 25,780 24,261 11,779 Deposits at amortised cost (10,513) (8,741) (3,104) Debt securities in issue (2,847) (3,030) (1,473) Subordinated liabilities (2,990) (2,697) (966) Cash collateral (2,185) (2,206) (396) Other 2 (500) (934) (442) Interest and similar expense (19,035) (17,608) (6,381) Net interest income 6,745 6,653 5,398 Notes 1 Includes interest income from reverse repurchase agreements and other similar secured lending at amortised cost and negative interest on liabilities 2 Includes interest expense from repurchase agreement and other similar secured lending at amortised cost and negative expense on assets Interest and similar income presented above represents interest revenue calculated using the effective interest method.

Fee and commission income (expense) [abstract]
Net fee and commission income	Net fee and commission income Accounting for net fee and commission income The Barclays Bank Group recognises fee and commission income charged for services provided by the Barclays Bank Group as and when performance obligations are satisfied, for example, on completion of the underlying transaction. Incremental costs are reported within fee and commission expense if they are directly attributable to generating identifiable fee and commission income. Where the contractual arrangements also result in the Barclays Bank Group recognising financial instruments in scope of IFRS 9, such financial instruments are initially recognised at fair value in accordance with IFRS 9 before applying the provisions of IFRS 15. Fee and commission income is disaggregated below by fee types that reflect the nature of the services offered across the Barclays Bank Group and operating segments, in accordance with IFRS 15 . The below table includes a total for fees in scope of IFRS 15 .

These include interchange and merchant fee income generated from credit and bank card usage. Transaction and processing fees are recognised at the point in time the transaction occurs or service is performed. Interchange and merchant fees are recognised upon settlement of the card transaction payment. The Barclays Bank Group incurs certain card related costs including those related to cardholder reward programmes and payments to co- brand partners. Cardholder reward programme costs related to customers that settle their outstanding balance each period (transactors) are expensed when incurred and presented in fee and commission expense, while costs related to customers that continuously carry an outstanding balance (revolvers) are included in the effective interest rate of the receivable (refer to Note 3). Payments to partners for new cardholder account originations related to transactor accounts are deferred as costs to obtain a contract under IFRS 15 , while costs related to revolver accounts are included in the effective interest rate of the receivable (refer to Note 3). Those costs deferred under IFRS 15 are capitalised and amortised over the estimated life of the customer relationship. Payments to co-brand partners based on revenue sharing to the extent the revenue share relates to "revolvers" are included in the effective interest rate of the receivable and to the extent revenue share relates to “transactors” it must be presented in fee and commission expense. Payments based on profitability are presented in fee and commission expense. Advisory Advisory fees are generated from wealth management services and investment banking advisory services related to mergers, acquisitions and financial restructurings. Wealth management advisory fees are earned over the period the services are provided and are generally recognised quarterly when the market value of client assets is determined. Investment banking advisory fees are recognised at the point in time when the services related to the transaction have been completed under the terms of the engagement. Investment banking advisory costs are recognised as incurred in fee and commission expense if direct and incremental to the advisory services or are otherwise recognised in operating expenses. Brokerage and execution Brokerage and execution fees are earned for executing client transactions with various exchanges and over-the-counter markets and assisting clients in clearing transactions and facilitating foreign exchange transactions for spot/forward contracts. Brokerage and execution fees are recognised at the point in time the associated service has been completed which is generally the trade date of the transaction. Underwriting and syndication Underwriting and syndication fees are earned for the distribution of client equity or debt securities and the arrangement and administration of a loan syndication. This includes commitment fees to provide loan financing. Underwriting fees are generally recognised on trade date if there is no remaining contingency, such as the transaction being conditional on the closing of an acquisition or another transaction. Underwriting costs are deferred and recognised in fee and commission expense when the associated underwriting fees are recorded. Syndication fees are earned for arranging and administering a loan syndication; however, the associated fee may be subject to variability until the loan has been syndicated to other syndicate members or until other contingencies have been resolved and therefore the fee revenue is deferred until the uncertainty is resolved. Included in underwriting and syndication fees are loan commitment fees, when the draw down is not probable. Such commitment fees are recognised over time through to the contractual maturity of the commitment. Contract assets and contract liabilities The Barclays Bank Group had no material contract assets or contract liabilities as at 31 December 2024 ( 2023 : £nil ; 2022 : £nil ). Impairment of fee receivables and contract assets During 2024 , there have been no material impairments recognised in relation to fees receivable and contract assets ( 2023 : £nil ; 2022 : £nil ). Fees in relation to transactional business can be added to outstanding customer balances. These amounts may be subsequently impaired as part of the overall loans and advances balance. Remaining performance obligations The Barclays Bank Group applies the practical expedient of IFRS 15 and does not disclose information about remaining performance obligations that have original expected durations of one year or less or because the Barclays Bank Group has a right to consideration that corresponds directly with the value of the service provided to the client or customer. Costs incurred in obtaining or fulfilling a contract The Barclays Bank Group expects that incremental costs of obtaining a contract such as success fee and commission fees paid are recoverable and therefore capitalises such contract costs. Capitalised contract costs net of amortisation as at 31 December 2024 are £103m ( 2023 : £203m ; 2022 : £190m ). Capitalised contract costs are amortised over the customer relationship period depending on the transfer of services to which the asset pertains. In 2024 , the amount of amortisation was £58m ( 2023 : £52m ; 2022 : £45m ) and there was no impairment loss recognised in connection with the capitalised contract costs ( 2023 : £nil ; 2022 : £nil ).

Disclosure of impairment loss and reversal of impairment loss [abstract]
Credit impairment charges/(releases)	Credit impairment charges/(releases ) Accounting for the impairment of financial assets Impairment In accordance with IFRS 9 , the Barclays Bank Group is required to recognise expected credit losses (ECLs) based on unbiased forward- looking information for all financial assets at amortised cost, lease receivables, debt financial assets at fair value through other comprehensive income, loan commitments and financial guarantee contracts. Intercompany exposures in the individual financial statements, including loan commitments and financial guarantee contracts, are also in scope of IFRS 9 for ECL purposes. At the reporting date, an allowance (or provision for loan commitments and financial guarantees) is required for the 12 month (Stage 1 ) ECLs. If the credit risk has significantly increased since initial recognition (Stage 2), or if the financial instrument is credit impaired (Stage 3), an allowance (or provision) should be recognised for the lifetime ECLs. The measurement of ECL is calculated using three main components: (i) probability of default (PD) (ii) loss given default (LGD) and (iii) the exposure at default (EAD). The 12 month and lifetime ECLs are calculated by multiplying the respective PD, LGD and the EAD. The 12 month and lifetime PDs represent the PD occurring over the next 12 months and the remaining maturity of the instrument respectively. The EAD represents the expected balance at default, taking into account the repayment of principal and interest from the balance sheet date to the default event together with any expected drawdowns of committed facilities. The LGD represents expected losses on the EAD given the event of default, taking into account, among other attributes, the mitigating effect of collateral value at the time it is expected to be realised and the time value of money. Expected credit loss measurement is based on the ability of borrowers to make payments as they fall due. The Barclays Bank Group also considers sector specific risks and whether additional adjustments are required in the measurement of ECL. Credit risk may be impacted by climate considerations for certain sectors, such as oil and gas. Determining a significant increase in credit risk since initial recognition: The Barclays Bank Group assesses when a significant increase in credit risk has occurred based on quantitative and qualitative assessments. The credit risk of an exposure is considered to have significantly increased when: i) Quantitative test The annualised lifetime PD has increased by more than an agreed threshold relative to the equivalent at origination. PD deterioration thresholds are defined as percentage increases, and are set at an origination score band and segment level to ensure the test appropriately captures significant increases in credit risk at all risk levels. Generally, thresholds are inversely correlated to the origination PD, i.e. as the origination PD increases, the threshold value reduces. The assessment of the point at which a PD increase is deemed ‘significant’ is based upon analysis of the portfolio’s risk profile against a common set of principles and performance metrics (consistent across both retail and wholesale businesses), incorporating expert credit judgement where appropriate. Application of quantitative PD floors does not represent the use of the low credit risk exemption as exposures can separately move into stage 2 via the qualitative route described below. Wholesale assets apply a 100% increase in PD and 0.2% PD floor to determine a significant increase in credit risk. Retail assets apply bespoke relative increase and absolute PD thresholds based on product type and origination PD. Thresholds are subject to maximums defined by Barclays Bank Group policy and typically apply minimum relative thresholds of 50% - 100% and a maximum relative threshold of 400% For existing/historical exposures where origination point scores or data are no longer available or do not represent a comparable estimate of lifetime PD, a proxy origination score is defined, based upon: ▪ back-population of the approved lifetime PD score either to origination date or, where this is not feasible, as far back as possible (subject to a data start point no later than 1 January 2015); or ▪ use of available historical account performance data and other customer information, to derive a comparable ‘proxy’ estimation of origination PD. ii) Qualitative test This is relevant for accounts that meet the portfolio’s ‘high risk’ criteria and are subject to closer credit monitoring. High risk customers may not be in arrears but either through an event or an observed behaviour exhibit credit distress. The definition and assessment of high risk includes as wide a range of information as reasonably available, such as industry and Barclays Bank Group-wide customer level data, including but not limited to bureau scores and high consumer indebtedness index, wherever possible or relevant. Whilst the high risk populations applied for IFRS 9 impairment purposes are aligned with risk management processes, they are also regularly reviewed and validated to ensure that they capture any incremental segments where there is evidence of credit deterioration. iii) Backstop criteria This is relevant for accounts that are more than 30 calendar days past due. The 30 days past due criteria is a backstop rather than a primary driver of moving exposures into Stage 2 . The criteria for determining a significant increase in credit risk for assets with bullet repayments follows the same principle as all other assets, i.e. quantitative, qualitative and backstop tests are all applied. Exposures will move back to Stage 1 once they no longer meet the criteria for a significant increase in credit risk. This means that, at a minimum all payments must be up-to-date, the PD deterioration test is no longer met, the account is no longer classified as high risk, and the customer has evidenced an ability to maintain future payments. Exposures are only removed from Stage 3 and re-assigned to Stage 2 once the original default trigger event no longer applies. Exposures being removed from Stage 3 must no longer qualify as credit impaired, and: a) the obligor will also have demonstrated consistently good payment behaviour over a 12 -month period, by making all consecutive contractual payments due and, for forborne exposures, the relevant EBA defined probationary period has also been successfully completed; or b) (for non-forborne exposures) the performance conditions are defined and approved within an appropriately sanctioned restructure plan, including 12 months’ payment history have been met. Management overlays and other exceptions to model outputs are applied only if consistent with the objective of identifying significant increases in credit risk. Forward-looking information The measurement of ECL involves complexity and judgement, including estimation of PD, LGD, a range of unbiased future economic scenarios, estimation of expected lives (where contractual life is not appropriate), and estimation of EAD and assessing significant increases in credit risk. Credit losses are the expected cash shortfalls from what is contractually due over the expected life of the financial instrument, discounted at the original effective interest rate (EIR). ECLs are the unbiased probability-weighted credit losses determined by evaluating a range of possible outcomes and considering future economic conditions. Refer to the Measurement uncertainty and sensitivity analysis section on page 93 for further details. Definition of default, credit impaired assets, write-offs, and interest income recognition The definition of default for the purpose of determining ECLs, and for internal credit risk management purposes, has been aligned to the Regulatory Capital CRR Article 178 definition of default, to maintain a consistent approach with IFRS 9 and associated regulatory guidance. The Regulatory Capital CRR Article 178 definition of default considers indicators that the debtor is unlikely to pay, includes exposures in forbearance and is no later than when the exposure is more than 90 days past due. When exposures are identified as credit impaired at the time when they are purchased or originated, interest income is calculated on the carrying value net of the impairment allowance. An asset is considered credit impaired when one or more events occur that have a detrimental impact on the estimated future cash flows of the financial asset. This comprises assets defined as defaulted and other individually assessed exposures where imminent default or actual loss is identified. Uncollectible loans are written off against the related allowance for loan impairment on completion of the Barclays Bank Group’s internal processes and when all reasonably expected recoverable amounts have been collected. Subsequent recoveries of amounts previously written off are credited to the income statement. The timing and extent of write-offs may involve some element of subjective judgement. Nevertheless, a write-off will often be prompted by a specific event, such as the inception of insolvency proceedings or other formal recovery action, which makes it possible to establish that some or the entire advance is beyond realistic prospect of recovery. Accounting for purchased financial guarantee contracts The Barclays Bank Group may enter into a financial guarantee contract which requires the issuer of such contract to reimburse the Barclays Bank Group for a loss it incurs because a specified debtor fails to make payment when due in accordance with the terms of a debt instrument. For these separate financial guarantee contracts, the Barclays Bank Group recognises a reimbursement asset aligned with the recognition of the underlying ECLs, if it is considered virtually certain that a reimbursement would be received if the specified debtor fails to make payment when due in accordance with the terms of the debt instrument. Loan modifications and renegotiations that are not credit-impaired When modification of a loan agreement occurs as a result of commercial restructuring activity rather than due to the credit risk of the borrower, an assessment must be performed to determine whether the terms of the new agreement are substantially different from the terms of the existing agreement. This assessment considers both the change in cash flows arising from the modified terms as well as the change in overall instrument risk profile. In respect of payment holidays granted to borrowers which are not due to forbearance, if the revised cash flows on a present value basis (based on the original EIR) are not substantially different from the original cash flows, the loan is not considered to be substantially modified. Where terms are substantially different, the existing loan will be derecognised and a new loan will be recognised at fair value, with any difference in valuation recognised immediately within the income statement, subject to observability criteria. Where terms are not substantially different, the loan carrying value will be adjusted to reflect the present value of modified cash flows discounted at the original EIR, with any resulting gain or loss recognised immediately within the income statement as a modification gain or loss. Expected life Lifetime ECLs must be measured over the expected life. This is restricted to the maximum contractual life and takes into account expected prepayment, extension, call and similar options. The exceptions are certain revolver financial instruments, such as credit cards and bank overdrafts, that include both a drawn and an undrawn component where the entity’s contractual ability to demand repayment and cancel the undrawn commitment does not limit the entity’s exposure to credit losses to the contractual notice period. For revolving facilities, expected life is analytically derived to reflect the behavioural life of the asset, i.e. the full period over which the business expects to be exposed to credit risk. Behavioural life is typically based upon historical analysis of the average time to default, closure or withdrawal of facility. Where data is insufficient or analysis inconclusive, an additional ‘maturity factor’ may be incorporated to reflect the full estimated life of the exposures, based upon experienced judgement and/or peer analysis. Potential future modifications of contracts are not taken into account when determining the expected life or EAD until they occur. Discounting ECLs are discounted at the EIR at initial recognition or an approximation thereof and consistent with income recognition. For loan commitments the EIR is the rate that is expected to apply when the loan is drawn down and a financial asset is recognised. Issued financial guarantee contracts are discounted at the risk-free rate. Lease receivables are discounted at the rate implicit in the lease. For variable/ floating rate financial assets, the spot rate at the reporting date is used and projections of changes in the variable rate over the expected life are not made to estimate future interest cash flows or for discounting. Modelling techniques Currently, Internal Ratings-Based models are leveraged to calculate the point-in-time PD and LGD, which serve as key inputs to the IFRS 9 models. Thereafter, these inputs are extrapolated by the IFRS 9 models to create macroeconomic sensitive forecast of PDs, LGDs and in turn ECL. Forbearance A financial asset is subject to forbearance when it is modified due to the credit distress of the borrower. A modification made to the terms of an asset due to forbearance will typically be assessed as a non-substantial modification that does not result in derecognition of the original loan, except in circumstances where debt is exchanged for equity. Both performing and non-performing forbearance assets are classified as Stage 3 except where it is established that the concession granted has not resulted in diminished financial obligation and that no other regulatory definitions of default criteria have been triggered, in which case the asset is classified as Stage 2 . The minimum probationary period for non-performing forbearance is 12 months and for performing forbearance, 24 months . Hence, a minimum of 36 months is required for non-performing forbearance to move out of a forborne state. No financial instrument in forbearance can transfer back to Stage 1 until all of the Stage 2 thresholds are no longer met and can only move out of Stage 3 when no longer credit impaired. Critical accounting estimates and judgements IFRS 9 impairment involves several important areas of judgement, including estimating forward looking modelled parameters (PD, LGD and EAD), developing a range of unbiased future economic scenarios, estimating expected lives and assessing significant increases in credit risk, based on the Barclays Bank Group’s experience of managing credit risk. The determination of expected life is most material for Barclays Bank Group's credit card portfolios which is obtained via behavioural life analysis to materially capture the risk of these facilities. Within the retail and small businesses portfolios, which comprise large numbers of small homogenous assets with similar risk characteristics where credit scoring techniques are generally used, the impairment allowance is calculated using forward looking modelled parameters which are typically run at account level. There are many models in use, each tailored to a product, line of business or customer category. Judgement and knowledge is needed in selecting the statistical methods to use when the models are developed or revised. Management adjustments to impairment models, which contain an element of subjectivity, are applied in order to factor in certain conditions or changes in policy that are not fully incorporated into the impairment models, or to reflect additional facts and circumstances at the period end. Management adjustments are reviewed and incorporated into future model development where appropriate . For individually significant assets in Stage 3 , impairment allowances are calculated on an individual basis and all relevant considerations that have a bearing on the expected future cash flows across a range of economic scenarios are taken into account. These considerations can be particularly subjective and can include the business prospects for the customer, the realisable value of collateral, the Barclays Bank Group’s position relative to other claimants, the reliability of customer information and the likely cost and duration of the work-out process. The level of the impairment allowance is the difference between the value of the discounted expected future cash flows (discounted at the loan’s original effective interest rate), and its carrying amount. Furthermore, judgements change with time as new information becomes available or as work-out strategies evolve, resulting in frequent revisions to the impairment allowance as individual decisions are taken. Changes in these estimates would result in a change in the allowances and have a direct impact on the impairment charge. Temporary adjustments to calculated IFRS 9 impairment allowances may be applied in limited circumstances to account for situations where known or expected risk factors or information have not been considered in the ECL assessment or modelling process. For further information please see pages 91 to 92 in credit risk performance. Information about the potential impact of the physical and transition risks of climate change on borrowers is considered, taking into account reasonable and supportable information to make accounting judgements and estimates. Climate change is inherently of a long- term nature, with significant levels of uncertainty, and consequently requires judgement in determining the possible impact in the next financial year, if any. 2024 2023 2022 Impairment charges / (releases) Recoveries and reimburseme nts 1 Total 2 Impairment charges / (releases) Recoveries and reimbursem ents 1 Total Impairment charges / (releases) Recoveries and reimburseme nts 1 Total £m £m £m £m £m £m £m £m £m Loans and advances at amortised cost 3 1,687 (42) 1,645 1,656 (41) 1,615 1,118 (228) 890 Off-balance sheet loan commitments and financial guarantee contracts (34) — (34) (37) — (37) 7 — 7 Total 1,653 (42) 1,611 1,619 (41) 1,578 1,125 (228) 897 Cash collateral and settlement balances (3) — (3) 4 — 4 28 — 28 Financial instruments at fair value through other comprehensive income 1 — 1 (2) — (2) 8 — 8 Reverse Repo 8 — 8 — — — — — — Other financial asset measured at cost — — — (2) — (2) — — — Credit impairment charges /(releases) 1,659 (42) 1,617 1,619 (41) 1,578 1,161 (228) 933 Notes 1 Recoveries and reimbursements include £ 11 m (2023: £ 24 m , 2022: £ 195 m ) for reimbursements expected to be received under the arrangement where the Barclays Bank Group has entered into financial guarantee contracts which provide credit protection over certain assets with third parties and cash recoveries of previously written off amounts of £ 31 m (2023: £ 17 m , 2022: £ 33 m ). 2 Includes net impairment charge relating to portfolios classified as held for sale.

Major components of tax expense (income) [abstract]
Tax	Tax Accounting for income taxes The Barclays Bank Group applies IAS 12 Income Taxes in accounting for taxes on income. Income tax payable on taxable profits (current tax) is recognised as an expense in the periods in which the profits arise. Withholding taxes are also treated as income taxes. Income tax recoverable on tax allowable losses is recognised as a current tax asset only to the extent that it is regarded as recoverable by offsetting against taxable profits arising in the current or prior periods. Current tax is measured using tax rates and tax laws that have been enacted or substantively enacted at the balance sheet date. Deferred tax assets are recognised to the extent that it is probable that taxable profit will be available against which the deductible temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilised. Deferred tax liabilities are recognised for all taxable temporary differences except for the initial recognition of goodwill. Deferred tax is not recognised where the temporary difference arises from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss. Deferred tax is determined using tax rates and legislation enacted or substantively enacted by the balance sheet date which are expected to apply when the deferred tax asset is realised or the deferred tax liability is settled. Deferred tax assets and liabilities are only offset when there is both a legal right to set-off and an intention to settle on a net basis. The Barclays Bank Group has adopted the International Tax Reform - Pillar Two Model Rules amendments to IAS 12, which were issued on 23 May 2023 and approved by the UK Endorsement Board on 19 July 2023, and has applied the exception set out in paragraph 4A in respect of recognising and disclosing information about deferred tax assets and liabilities related to Pillar Two income taxes. The Barclays Bank Group considers an uncertain tax position to exist when it considers that ultimately, in the future, the amount of profit subject to tax may be greater than the amount initially reflected in the Barclays Bank Group’s tax returns. The Barclays Bank Group accounts for provisions in respect of uncertain tax positions in two different ways. A current tax provision is recognised when it is considered probable that the outcome of a review by a tax authority of an uncertain tax position will alter the amount of cash tax due to, or from, a tax authority in the future. From recognition, the current tax provision is then measured at the amount the Barclays Bank Group ultimately expects to pay the tax authority to resolve the position. The accrual of interest and penalty amounts in respect of uncertain income tax positions is recognised as an expense within profit before tax. Deferred tax provisions are adjustments made to the carrying value of deferred tax assets in respect of uncertain tax positions. A deferred tax provision is recognised when it is considered probable that the outcome of a review by a tax authority of an uncertain tax position will result in a reduction in the carrying value of the deferred tax asset. From recognition of a provision, measurement of the underlying deferred tax asset is adjusted to take into account the expected impact of resolving the uncertain tax position on the loss or temporary difference giving rise to the deferred tax asset. The approach taken to measurement takes account of whether the uncertain tax position is a discrete position that will be reviewed by the tax authority in isolation from any other position, or one of a number of issues which are expected to be reviewed together concurrently and resolved simultaneously with a tax authority. The Barclays Bank Group’s measurement of provisions is based upon its best estimate of the additional profit that will become subject to tax. For a discrete position, consideration is given only to the merits of that position. Where a number of issues are expected to be reviewed and resolved together, the Barclays Bank Group will take into account not only the merits of its position in respect of each particular issue but also the overall level of provision relative to the aggregate of the uncertain tax positions across all the issues that are expected to be resolved at the same time. In addition, in assessing provision levels, it is assumed that tax authorities will review uncertain tax positions and that all facts will be fully and transparently disclosed. Critical accounting estimates and judgements There are two key areas of judgement that impact the reported tax position. Firstly, the level of provisioning for uncertain tax positions; and secondly, the recognition and measurement of deferred tax assets. The Barclays Bank Group does not consider there to be a significant risk of a material adjustment to the carrying amount of current and deferred tax balances, including provisions for uncertain tax positions in the next financial year. The provisions for uncertain tax positions cover a diverse range of issues and reflect advice from external counsel where relevant. It should be noted that only a proportion of the total uncertain tax positions will be under audit at any point in time, and could therefore be subject to challenge by a tax authority over the next year. Deferred tax assets have been recognised based on business profit forecasts which included consideration for the current view of climate impacts. Details on the recognition of deferred tax assets are provided in this note. 2024 2023 2022 £m £m £m Current tax charge/(credit) Current year 680 605 623 Adjustments in respect of prior years 42 (96) (625) 722 509 (2) Deferred tax charge Current year 239 43 19 Adjustments in respect of prior years 38 110 468 277 153 487 Tax charge 999 662 485 The table below shows the reconciliation between the actual tax charge and the tax charge that would result from applying the standard UK corporation tax rate to the Barclays Bank Group’s profit before tax. 2024 2024 2023 2023 2022 2022 £m % £m % £m % Profit before tax from continuing operations 4,747 4,223 4,867 Tax charge based on the applicable UK corporation tax rate of 25% (2023: 23.5% , 2022: 19% ) 1,187 25.0% 992 23.5% 925 19.0% Impact of profits/losses earned in territories with different statutory rates to the UK (weighted average tax rate is 23% ( 2023 : 23.6% , 2022 : 22.3% )) (95) (2.0%) 3 0.1% 160 3.3% Recurring items: Non-creditable taxes including withholding taxes 95 2.0% 124 3.0% 117 2.4% Adjustments in respect of prior years 80 1.7% 14 0.3% (157) (3.2%) Changes in recognition of deferred tax and effect of unrecognised tax losses 69 1.5% (58) (1.4%) (146) (3.0%) Impact of UK bank levy being non-deductible 47 1.0% 35 0.8% 28 0.6% Non-deductible expenses 44 0.9% 47 1.1% 28 0.6% Banking surcharge 1 and other items (32) (0.7%) (74) (1.8%) (12) (0.3%) Non-taxable gains and income (74) (1.6%) (60) (1.4%) (129) (2.6%) Tax relief on holdings of inflation-linked government bonds (157) (3.3%) (194) (4.6%) (510) (10.5%) Tax relief on payments made under AT1 instruments (189) (4.0%) (174) (4.1%) (136) (2.8%) Non-recurring items: Remeasurement of UK deferred tax assets due to tax rate changes — — — — 183 3.8% Non-deductible provisions for investigations and litigation 2 0.0% — — 85 1.7% Non-deductible provisions for UK customer redress 22 0.5% 7 0.2% 49 1.0% Total tax charge 999 21.0% 662 15.7% 485 10.0% Note 1 Banking surcharge includes the impact of the 3% UK banking surcharge rate on profits/losses and tax adjustments relating to UK banking entities . Factors influencing the effective tax rate The effective tax rate of 21% is lower than the UK corporation tax rate of 25% primarily due to tax relief on payments made under AT1 instruments and tax relief on holdings of inflation-linked government bonds. These factors, which have each decreased the effective tax rate, are partially offset by non-creditable taxes including withholding taxes. Factors that may influence the effective tax rate in future periods The Barclays Bank Group’s future tax charge will be sensitive to the geographic mix of profits earned, the tax rates in force and changes to the tax rules in the jurisdictions that the Barclays Bank Group operates in. Tax law is, at times, complex, and it is the role of courts and tribunals to act as the final authority on the correct interpretation of tax law. In October 2023, a First-tier Tax Tribunal hearing took place between Barclays Bank PLC and HM Revenue & Customs (HMRC) in respect of the UK corporation tax treatment of an element of the finance costs associated with reserve capital instruments issued as part of the capital raising announced by Barclays in October 2008, which have since been redeemed. The judgment was handed down in March 2024 and was in HMRC’s favour. In January 2025, Barclays was granted permission from the Upper Tribunal to appeal against the judgment. A provision is carried that is expected to be sufficient to cover the tax cost (once tax attributes that are available to partially offset a potential tax liability in respect of this issue are taken into account) in the event that the appeal is unsuccessful and the existing judgment were to stand. The UK Government enacted legislation in 2023 to implement the OECD's global minimum tax rules (the Pillar Two rules) and a UK domestic minimum tax. The rules apply from 1 January 2024 and apply in respect of profits for every jurisdiction where the Barclays Bank Group operates. Additional taxes resulting from the implementation of Pillar Two of £ 14 m have arisen in respect of a limited number of jurisdictions in which the Barclays Bank Group operates, principally in the Isle of Man, Jersey, and Guernsey, by virtue of their low statutory tax rates. It is not expected that additional taxes will significantly increase the Barclays Bank Group’s tax charge in future periods. Additionally, the Barclays Bank Group may be subject to Qualifying Domestic Minimum Top-up Taxes (QDMTTs) under the Pillar Two rules implemented in its operating jurisdictions. The application of QDMTT rules should not affect the overall impact of any additional taxes resulting from the Pillar Two regime on the Barclays Bank Group’s tax charge, as any taxes paid under a local QDMTT would be expected to result in a reduction in any top-up tax being payable in the UK. The Barclays Bank Group will continue to review and assess the impact of further guidance released by the OECD and governments implementing this new tax regime.

Tax included directly in equity Tax included directly in equity comprises a £ 94 m credit ( 2023 : £13m credit ) relating to share-based payments and deductible costs on issuing other equity instruments. Deferred tax assets and liabilities The deferred tax amounts on the balance sheet were as follows: Barclays Bank Group 2024 2023 £m £m UK Tax Group 2,315 2,054 US Intermediate Holding Company Tax Group ("IHC Tax Group") 1,162 973 Barclays Bank PLC's US Branch Tax Group 270 386 Other (outside the UK and US tax groups) 386 475 Deferred tax asset 4,133 3,888 Deferred tax liability - UK Tax Group (2) (3) Net deferred tax 4,131 3,885 UK Tax Group deferred tax assets and liabilities The net deferred tax asset in the UK Tax Group of £ 2,315 m ( 2023 : £2,054m ) includes a deferred tax asset of £ 1,066 m ( 2023 : £1,241m ) relating to tax losses with the balance relating to temporary differences. There is no time limit on utilisation of UK tax losses and business profit forecasts indicate these losses will be fully recovered. US deferred tax assets in the IHC and the US Branch Tax Groups The deferred tax asset in the IHC Tax Group of £ 1,162 m ( 2023 : £973m ) includes £ 38 m ( 2023 : £35m ) relating to tax losses, with the balance relating to temporary differences. The deferred tax asset in Barclays Bank PLC’s US Branch Tax Group of £ 270 m ( 2023 : £386m ) relates entirely to temporary differences. In relation to the IHC Tax Group, these temporary differences include £ 365 m ( 2023 : £387m ) arising from New York State and City prior net operating loss conversion which can be carried forward and will expire in 2034. Business profit forecasts indicate that these amounts will be utilised prior to expiry. Other deferred tax assets (outside the UK and US tax groups) The deferred tax asset of £ 386 m ( 2023 : £475m ) in other entities within the Barclays Bank Group includes £ 111 m ( 2023 : £147m ) relating to tax losses. These deferred tax assets relate to a number of different territories and their recognition is based on profit forecasts or local country law which indicate that it is probable that those deferred tax assets will be fully recovered. Of the deferred tax asset of £ 386 m ( 2023 : £475m ), an amount of £ 4m ( 2023 : £20m ) relates to entities which have suffered a loss in either the current or prior year and for which the utilisation of the deferred tax is dependent on future taxable profits . This has been taken into account in reaching the above conclusion that these deferred tax assets will be fully recovered in the future. The table below shows movements on deferred tax assets and liabilities during the year. The amounts are different from those disclosed on the balance sheet and in the preceding table as they are presented before offsetting asset and liability balances where there is a legal right to set-off and an intention to settle on a net basis.

The amount of deferred tax asset expected to be recovered after more than 12 months for the Barclays Bank Group is £4,662m ( 2023 : £3,577m ). The amount of deferred tax liability expected to be settled after more than 12 months for the Barclays Bank Group is £1,021m ( 2023 : £1,145m ). These amounts are before offsetting asset and liability balances where there is a legal right to set-off and an intention to settle on a net basis. Unrecognised deferred tax Tax losses and temporary differences The Barclays Bank Group has deferred tax assets not recognised in respect of gross deductible temporary differences of £ 373 m ( 2023 : £527m ), unused tax credits of £ 359 m ( 2023 : £381m ), and gross tax losses of £ 21,021 m ( 2023 : £21,373m ). The tax losses include capital losses of £ 3,629 m ( 2023 : £3,657m ). Of these tax losses, £ 13 m ( 2023 : £79m ) expire within five years , £ 6 m ( 2023 : £13m ) expire within six to ten years , £ 11,789 m ( 2023 : £10,504m ) expire within eleven to twenty years and £ 9,213 m ( 2023 : £10,777m ) can be carried forward indefinitely. Deferred tax assets have not been recognised in respect of these items because it is not probable that future taxable profits and gains will be available against which they can be utilised. Barclays Bank Group investments in subsidiaries, branches and associates Deferred tax is not recognised in respect of the value of Barclays Bank Group's investments in subsidiaries, branches and associates where the Barclays Bank Group is able to control the timing of the reversal of the temporary differences and it is probable that such differences will not reverse in the foreseeable future. The aggregate amount of these temporary differences for which deferred tax liabilities have not been recognised was £873 m ( 2023 : £870m ).

Financial assets at fair value through profit or loss [abstract]
Financial assets at fair value through the income statement	Financial assets at fair value through the income statemen t Accounting for financial assets designated at fair value Financial assets, other than those held for trading, are classified in this category if they are so irrevocably designated at inception and the use of the designation removes or significantly reduces an accounting mismatch. Subsequent changes in fair value for these instruments are recognised in the income statement in net investment income, except if reporting it in trading income reduces an accounting mismatch. The details on how the fair value amounts are derived for financial assets at fair value are described in Note 16. Accounting for financial assets mandatorily at fair value Financial assets that are held for trading are recognised at fair value through profit or loss. In addition, financial assets are held at fair value through profit or loss if they do not contain contractual terms that give rise on specified dates to cash flows that are Solely Payments of Principal and Interest (SPPI), or if the financial asset is not held in a business model that is either (i) a business model to collect the contractual cash flows or (ii) a business model that is achieved by both collecting contractual cash flows and selling.

Disclosure of nature and extent of risks arising from financial instruments [abstract]
Derivative financial instruments	Derivative financial instruments Accounting for derivatives Derivative instruments are contracts whose value is derived from one or more underlying financial instruments or indices defined in the contract. They include swaps, forward-rate agreements, futures, options and combinations of these instruments and primarily affect the Barclays Bank Group’s net interest income, net trading income and derivative assets and liabilities. Notional amounts of the contracts are not recorded on the balance sheet. Derivatives are used to hedge interest rate, credit risk, inflation risk, exchange rate, commodity, equity exposures and exposures to certain indices such as house price indices and retail price indices related to non-trading positions. All derivative instruments are held at fair value through profit or loss, except for derivatives that are in a designated cash flow or net investment hedge accounting relationship. Derivatives are classified as assets when their fair value is positive or as liabilities when their fair value is negative. Hedge accounting The Barclays Bank Group applies the requirements of IAS 39 Financial Instruments: Recognition and Measurement for hedge accounting purposes. The Barclays Bank Group applies hedge accounting to represent the economic effects of its interest rate, currency and contractually linked inflation risk management strategies. Where derivatives are held for risk management purposes, and when transactions meet the required criteria for documentation and hedge effectiveness, the Barclays Bank Group applies fair value hedge accounting, cash flow hedge accounting, or hedging of a net investment in a foreign operation, as appropriate to the risks being hedged. Fair value hedge accounting Changes in fair value of derivatives that qualify and are designated as fair value hedges are recorded in the income statement, together with changes in the fair value of the hedged asset or liability that are attributable to the hedged risk. The fair value changes adjust the carrying value of the hedged asset or liability held at amortised cost. If hedge relationships no longer meet the criteria for hedge accounting, hedge accounting is discontinued. For fair value hedges of interest rate risk, the fair value adjustment to the hedged item is amortised to the income statement over the period to maturity of the previously designated hedge relationship using the effective interest method. If the hedged item is sold or repaid, the unamortised fair value adjustment is recognised immediately in the income statement. For items classified as fair value through other comprehensive income, the hedge accounting adjustment is included in other comprehensive income. Cash flow hedge accounting For qualifying cash flow hedges, the fair value gain or loss associated with the effective portion of the cash flow hedge is recognised initially in other comprehensive income, and then recycled to the income statement in the periods when the hedged item will affect profit or loss. Any ineffective portion of the gain or loss on the hedging instrument is recognised in the income statement immediately. 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 when the hedged item is ultimately recognised in the income statement. When a forecast transaction is no longer expected to occur, the cumulative gain or loss that was recognised in equity is immediately transferred to the income statement. Hedges of net investments The Barclays Bank Group’s net investments in foreign operations, including monetary items accounted for as part of the net investment, are hedged for foreign currency risks using both derivatives and foreign currency borrowings. Hedges of net investments are accounted for similarly to cash flow hedges; the effective portion of the gain or loss on the hedging instrument is being recognised directly in other comprehensive income and the ineffective portion being recognised immediately in the income statement. The cumulative gain or loss recognised in other comprehensive income is recognised in the income statement on the disposal or partial disposal of the foreign operation, or other reductions in the Barclays Bank Group’s investment in the operation.

At a consolidated level, currency risk also arises when the functional currency of subsidiaries are different from the parent ▪ Contractually linked inflation risk – arises from financial instruments within contractually specified inflation risk. The Barclays Bank Group does not hedge inflation risk that arises from other activities In order to hedge these risks, the Barclays Bank Group uses the following hedging instruments: ▪ Interest rate derivatives to swap interest rate exposure into either fixed or variable rates ▪ Currency derivatives to swap foreign currency exposures into the entity’s functional currency, and net investment exposure to local currency ▪ Inflation derivatives to swap inflation exposure into either fixed or variable interest rates In some cases, certain items which are economically hedged may be ineligible hedged items for the purposes of IAS 39 , such as core deposits and equity. In these instances, a proxy hedging solution can be utilised whereby portfolios of floating rate assets are designated as eligible hedged items in cash flow hedges. In some hedging relationships, the Barclays Bank Group designates risk components of hedged items as follows: ▪ Benchmark interest rate risk as a component of interest rate risk, such as the Risk Free Rate (RFR) component ▪ Inflation risk as a contractually specified component of a debt instrument ▪ Exchange rate risk for foreign currency financial assets or financial liabilities ▪ Components of cash flows of hedged items, for example certain interest payments for part of the life of an instrument Using the benchmark interest rate risk results in other risks, such as credit risk and liquidity risk, being excluded from the hedge accounting relationship. In respect of many of the Barclays Bank Group’s hedge accounting relationships, the hedged item and hedging instrument change frequently due to the dynamic nature of the risk management and hedge accounting strategy. The Barclays Bank Group applies hedge accounting to dynamic scenarios, predominantly in relation to interest rate risk, with a combination of hedged items in order for its financial statements to reflect as closely as possible the economic risk management undertaken. In some cases, if the hedge accounting objective changes, the relevant hedge accounting relationship is de-designated and is replaced with a different hedge accounting relationship. Changes in the GBP value of net investments due to foreign currency movements are captured in the currency translation reserve, resulting in a movement in CET 1 capital. The Barclays Bank Group mitigates this by matching the CET 1 capital movements to the revaluation of the foreign currency RWA exposures. Net investment hedges are designated where necessary to reduce the exposure to movement in a particular exchange rate to within limits mandated by Risk. As far as possible, existing external currency liabilities are designated as the hedging instruments. The hedging instruments share the same risk exposures as the hedged items. Hedge effectiveness is determined with reference to quantitative tests, predominantly regression testing, but to the extent hedging instruments are exposed to different risks than the hedged items, this could result in hedge ineffectiveness or hedge accounting failures. Sources of ineffectiveness include the following: ▪ Mismatches between the contractual terms of the hedged item and hedging instrument, including basis differences ▪ Changes in credit risk of the hedging instruments ▪ If a hedging relationship becomes over-hedged, for example in hedges of net investments if the net asset value designated at the start of the period falls below the amount of the hedging instrument ▪ Cash flow hedges using external swaps with non-zero fair values Hedged items in fair value hedges Barclays Bank Group Accumulated fair value adjustment included in carrying amount Carrying amount Total Of which: Accumulated fair value adjustment on items no longer in a hedge relationship Change in fair value used as a basis to determine ineffectiveness Hedge ineffectiveness recognised in the income statement 1 Hedged item statement of financial position classification and risk category £m £m £m £m £m 2024 Assets Loans and advances at amortised cost - Interest rate risk 711 (160) (1) (18) 4 - Inflation risk 318 219 102 (18) 7 Debt securities classified as amortised cost - Interest rate risk 7,673 (44) 8 50 66 - Inflation risk 8,348 (1,342) 2 (598) (29) Financial assets at fair value through other comprehensive income 2 - Interest rate risk 29,514 (1,162) (452) (132) 176 - Inflation risk 2,979 (96) (31) (59) (22) Total Assets 49,543 (2,585) (372) (775) 202 Liabilities Debt securities in issue - Interest rate risk (1,417) 8 (24) (18) 2 Subordinated liabilities - Interest rate risk (37,531) 2,257 1,182 398 (8) Deposits at amortised cost from banks and customers - Interest rate risk (8,596) (12) (1) (4) (2) Repurchase agreements and other similar secured borrowing at amortised cost - Interest rate risk — — — — — Total Liabilities (47,544) 2,253 1,157 376 (8) Total Hedged Items 1,999 (332) 785 (399) 194 Hedged items in fair value hedges Barclays Bank Group Accumulated fair value adjustment included in carrying amount Carrying amount Total Of which: Accumulated fair value adjustment on items no longer in a hedge relationship Change in fair value used as a basis to determine ineffectiveness Hedge ineffectiveness recognised in the income statement 1 Hedged item statement of financial position classification and risk category £m £m £m £m £m 2023 Assets Loans and advances at amortised cost - Interest rate risk 830 (154) (5) 34 (1) - Inflation risk 450 246 — 3 (5) Debt securities classified as amortised cost - Interest rate risk 2,394 (24) (21) 48 24 - Inflation risk 6,484 (755) 3 33 (19) Financial assets at fair value through other comprehensive income 2 - Interest rate risk 33,021 (1,173) (658) 964 158 - Inflation risk 2,052 (51) (62) 5 3 Total Assets 45,231 (1,911) (743) 1,087 160 Liabilities Debt securities in issue - Interest rate risk (3,935) (28) (52) (95) (1) Subordinated liabilities - Interest rate risk (29,306) 1,904 579 (593) 24 Deposits at amortised cost from banks and customers - Interest rate risk (10,766) (18) (2) (31) (2) Repurchase agreements and other similar secured borrowing at amortised cost - Interest rate risk (426) 14 14 (4) 0 Total Liabilities (44,433) 1,872 539 (723) 21 Total Hedged Items 798 (39) (204) 364 181 Notes 1 Hedge ineffectiveness is recognised in net interest income. 2 For items classified as fair value through other comprehensive income, the hedge accounting adjustment is not included in the carrying amount, but rather adjusts other comprehensive income.

Financial assets at fair value through other comprehensive income [abstract]
Financial assets at fair value through other comprehensive income	Financial assets at fair value through other comprehensive income Accounting for financial assets at fair value through other comprehensive income (FVOCI) Financial assets that are debt instruments held in a business model that is achieved by both collecting contractual cash flows and selling and that contain contractual terms that give rise on specified dates to cash flows that are SPPI are measured at FVOCI. They are subsequently re-measured at fair value and changes therein (except for those relating to impairment, interest income and foreign currency exchange gains and losses) are recognised in other comprehensive income until the assets are sold. Interest (calculated using the effective interest method) is recognised in the income statement in net interest income (Note 3). Upon disposal, the cumulative gain or loss recognised in other comprehensive income is included in net investment income (Note 6). In determining whether the business model is achieved by both collecting contractual cash flows and selling financial assets, it is determined that both collecting contractual cash flows and selling financial assets are integral to achieving the objective of the business model. The Barclays Bank Group will consider past sales and expectations about future sales to establish if the business model is achieved. For equity securities that are not held for trading, the Barclays Bank Group may make an irrevocable election on initial recognition to present subsequent changes in the fair value of the instrument in other comprehensive income (except for dividend income which is recognised in profit or loss).

Designated financial liabilities at fair value through profit or loss [abstract]
Financial liabilities designated at fair value	Financial liabilities designated at fair value Accounting for liabilities designated at fair value through profit and loss In accordance with IFRS 9, financial liabilities may be designated at fair value, with gains and losses taken to the income statement within net trading income (Note 5) and net investment income (Note 6). Movements in own credit are reported through other comprehensive income, unless the effects of changes in the liability's credit risk would create or enlarge an accounting mismatch in profit and loss. In these scenarios, all gains and losses on that liability (including the effects of changes in the credit risk of the liability) are presented in profit and loss. On derecognition of the financial liability no amounts relating to own credit risk are recycled to the income statement. The Barclays Bank Group has the ability to make the fair value designation when holding the instruments at fair value reduces an accounting mismatch (caused by an offsetting liability or asset being held at fair value), or is managed by the Barclays Bank Group on the basis of its fair value, or includes terms that have substantive derivative characteristics (Note 13). The details on how the fair value amounts are arrived at for financial liabilities designated at fair value are described in Note 16.

Disclosure of detailed information about financial instruments [abstract]
Fair value of financial instruments	Fair value of financial instruments Accounting for financial assets and liabilities – fair value Financial instruments that are held for trading are recognised at fair value through profit or loss. In addition, financial assets are held at fair value through profit or loss if they do not contain contractual terms that give rise on specified dates to cash flows that are SPPI, or if the financial asset is not held in a business model that is either (i) a business model to collect the contractual cash flows or (ii) a business model that is achieved by both collecting contractual cash flows and selling. Subsequent changes in fair value for these instruments are recognised in the income statement in net investment income, except if reporting it in trading income reduces an accounting mismatch. Wherever possible, fair value is determined by reference to a quoted market price for that instrument. For many of the Barclays Bank Group’s financial assets and liabilities, especially derivatives, quoted prices are not available and valuation models are used to estimate fair value. The models calculate the expected cash flows under the terms of each specific contract and then discount these values back to a present value. These models use as their basis independently sourced market inputs including, for example, interest rate yield curves, equities and commodities prices, option volatilities and currency rates. For financial liabilities measured at fair value, the carrying amount reflects the effect on fair value of changes in own credit spreads derived from observable market data such as in primary issuance and redemption activity for structured notes. On initial recognition, it is presumed that the transaction price is the fair value unless there is observable information available in an active market to the contrary. For valuations that have made use of unobservable inputs, the difference between the model valuation and the initial transaction price (Day One profit) is recognised in profit or loss either: on a straight-line basis over the term of the transaction; or over the period until all inputs will become observable where appropriate; or released in full when previously unobservable inputs become observable. Various factors influence the availability of observable inputs, and these may vary from product to product and change over time. Factors include the depth of activity in the relevant market, the type of product, whether the product is new and not widely traded in the marketplace, the maturity of market modelling and the nature of the transaction (bespoke or generic). To the extent that valuation is based on models or inputs that are not observable in the market, the determination of fair value can be more subjective, dependent on the significance of the unobservable input to the overall valuation. Unobservable inputs are determined based on the best information available, for example by reference to similar assets, similar maturities, or other analytical techniques. The sensitivity of valuations used in the financial statements to possible changes in significant unobservable inputs is shown on page 201 . Critical accounting estimates and judgements The valuation of financial instruments often involves a significant degree of judgement and complexity, in particular where valuation models make use of unobservable inputs (‘Level 3’ assets and liabilities). This note provides information on these instruments, including the related unrealised gains and losses recognised in the period, a description of significant valuation techniques and unobservable inputs, and a sensitivity analysis. Climate related risks are assumed to be included in the fair values of assets and liabilities traded in active markets. Within less active markets, for counterparties and instruments identified as being more susceptible to climate change risk, an impact assessment was performed by increasing their probability of default. The change in the valuation of the assets and liabilities from this assessment was not sufficiently material to necessitate any amendment to the reported 2024 year-end valuations. Valuation Assets and liabilities are classified according to a hierarchy that reflects the observability of significant market inputs. The three levels of the fair value hierarchy are defined below with judgement applied in determining the boundary between Level 2 and 3 classifications. Quoted market prices – Level 1 Assets and liabilities are classified as Level 1 if their value is observable in an active market. Such instruments are valued by reference to unadjusted quoted prices for identical assets or liabilities in active markets where the quoted price is readily available, and the price represents actual and regularly occurring market transactions. An active market is one in which transactions occur with sufficient volume and frequency to provide pricing information on an ongoing basis. Valuation technique using observable inputs – Level 2 Assets and liabilities classified as Level 2 have been valued using models whose inputs are observable either directly or indirectly. Valuations based on observable inputs include assets and liabilities such as swaps and forwards which are valued using market standard pricing techniques, and options that are commonly traded in markets where all the inputs to the market standard pricing models are observable. For certain instruments that derive a fair value using unobservable inputs that are not considered significant, then the asset or liability may be classified as Level 2. Valuation technique using significant unobservable inputs – Level 3 Assets and liabilities are classified as Level 3 if their valuation incorporates significant inputs that are not based on observable market data (unobservable inputs). A valuation input is considered observable if it can be directly observed from transactions in an active market, or if there is compelling external evidence demonstrating an executable exit price. Unobservable input levels are generally determined via reference to observable inputs, historical observations or using other analytical techniques. The following table shows assets and liabilities that are held at fair value disaggregated by valuation technique (fair value hierarchy) and balance sheet classification: Assets and liabilities held at fair value 2024 2023 Valuation technique using Valuation technique using Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Barclays Bank Group £m £m £m £m £m £m £m £m Trading portfolio assets 77,581 78,548 10,115 166,244 94,615 73,442 6,509 174,566 Financial assets at fair value through the income statement 3,463 182,391 5,991 191,845 5,747 193,121 5,368 204,236 Derivative financial assets 101 290,182 2,073 292,356 107 252,464 3,540 256,111 Financial assets at fair value through other comprehensive income 19,021 28,315 3,674 51,010 21,079 29,568 776 51,423 Investment property — — 9 9 — — 2 2 Total Assets 100,166 579,436 21,862 701,464 121,548 548,595 16,195 686,338 Trading portfolio liabilities (27,033) (28,754) (395) (56,182) (28,380) (29,013) (368) (57,761) Financial liabilities designated at fair value (181) (276,355) (3,241) (279,777) (117) (297,244) (1,212) (298,573) Derivative financial liabilities (86) (276,064) (3,181) (279,331) (81) (245,146) (4,653) (249,880) Total Liabilities (27,300) (581,173) (6,817) (615,290) (28,578) (571,403) (6,233) (606,214) The following table shows Barclays Bank Group’s Level 3 assets and liabilities that are held at fair value disaggregated by product type: As at 31 December 2024 Loans Corporate debt Asset backed securities Government debt Private equity investments Issued debt Reverse repurchase and repurchase agreements Interest rate derivatives Equity derivatives Other products 1 Total £m £m £m £m £m £m £m £m £m £m £m Trading portfolio assets 6,146 1,590 991 1,018 — — — — — 370 10,115 Financial assets at fair value through the income statement 3,991 913 139 35 219 — 539 — — 155 5,991 Derivative financial assets — — — — — — — 1,193 477 403 2,073 Financial assets at fair value through other comprehensive income 2,858 47 757 12 — — — — — — 3,674 Investment property — — — — — — — — — 9 9 Total assets 12,995 2,550 1,887 1,065 219 — 539 1,193 477 937 21,862 Trading portfolio liabilities — (374) (6) — — — — — — (15) (395) Financial liabilities designated at fair value — — — — — (1,842) (1,379) — — (20) (3,241) Derivative financial liabilities — — — — — — — (1,013) (1,219) (949) (3,181) Total Liabilities — (374) (6) — — (1,842) (1,379) (1,013) (1,219) (984) (6,817) As at 31 December 2023 Loans Corporate debt Asset backed securities Government debt Private equity investments Issued debt Reverse repurchase and repurchase agreements Interest rate derivatives Equity derivatives Other products 1 Total £m £m £m £m £m £m £m £m £m £m £m Trading portfolio assets 4,469 679 318 669 — — — — — 374 6,509 Financial assets at fair value through the income statement 3,984 889 85 — 145 — 209 — — 56 5,368 Derivative financial assets — — — — — — — 2,211 977 352 3,540 Financial assets at fair value through other comprehensive income 533 — 200 42 — — — — — 1 776 Investment property — — — — — — — — — 2 2 Total assets 8,986 1,568 603 711 145 — 209 2,211 977 785 16,195 Trading portfolio liabilities — (359) — — — — — — — (9) (368) Financial liabilities designated at fair value — — — — — (629) (517) — — (66) (1,212) Derivative financial liabilities — — — — — — — (1,701) (2,041) (911) (4,653) Total Liabilities — (359) — — — (629) (517) (1,701) (2,041) (986) (6,233) Note 1 Other products include funds and fund-linked products, equity cash products, investment property, foreign exchange derivatives and credit derivatives. Valuation techniques and sensitivity analysis Sensitivity analysis is performed on products with significant unobservable inputs (Level 3) to generate a range of reasonably possible alternative valuations. The sensitivity methodologies applied take account of nature of the valuation techniques used, as well as availability and reliability of observable proxy and historical data and impact of using alternative models. Sensitivities are dynamically calculated on a monthly basis. The calculation is based on range or spread data of a reliable reference source or a scenario based on relevant market analysis alongside the impact of using alternative models. Sensitivities are calculated without reflecting the impact of any diversification in the portfolio. The valuation techniques used, observability and sensitivity analysis for material products within Level 3, are described below. Interest rate derivatives Description: Derivatives linked to interest rates or inflation indices. The category includes futures, interest rate and inflation swaps, swaptions, caps, floors, inflation options, balance guaranteed swaps and other exotic interest rate derivatives. Valuation: Interest rate and inflation derivatives are generally valued using curves of forward rates constructed from market data to project and discount the expected future cash flows of trades. Instruments with optionality are valued using volatilities implied from market inputs and use industry standard or bespoke models depending on the product type. Observability: In general, inputs are considered observable up to liquid maturities which are determined separately for each input and underlying. Unobservable inputs are generally set by referencing liquid market instruments and applying extrapolation techniques or inferred via another reasonable method. Equity derivatives Description: Exchange traded or OTC derivatives linked to equity indices and single names. The category includes vanilla and exotic equity products. Valuation: Equity derivatives are valued using industry standard models. Valuation inputs include stock prices, dividends, volatilities, interest rates, equity repurchase curves and, for multi-asset products, correlations. Observability: In general, valuation inputs are observable up to liquid maturities which are determined separately for each input and underlying. Unobservable inputs are set by referencing liquid market instruments and applying extrapolation techniques or inferred via another reasonable method. Corporate debt Description: Primarily corporate bonds. Valuation: Corporate bonds are valued using observable market prices sourced from broker quotes, inter-dealer prices or other reliable pricing sources. Observability: Prices for actively traded bonds are considered observable. Unobservable bond prices are generally determined by reference to bond yields or CDS spreads for actively traded instruments issued by or referencing the same (or a similar) issuer. Reverse repurchase and repurchase agreements Description: Includes securities purchased under resale agreements, securities sold under repurchase agreements, and other similar secured lending agreements. The agreements are primarily short-term in nature. Valuation: Repurchase and reverse repurchase agreements are generally valued by discounting the expected future cash flows using industry standard models that incorporate market interest rates and repurchase rates, based on the specific details of the transaction. Observability: Inputs are deemed observable up to liquid maturities or for consensus pricing with low pricing-range and are determined based on the specific features of the transaction. Unobservable inputs are generally set by referencing liquid market instruments and applying extrapolation techniques or inferred via another reasonable method. Loans Description: A drawn lending facility issued to corporate clients and customers. Valuation: Loans are valued either using a price based approach or through models that discount expected future cash flows based on interest rates and loan spreads. Observability: Within this loan population, the price or loan spread may be unobservable. Private equity investments Description: Includes investments in equity holdings in operating companies not quoted on a public exchange. Valuation: Private equity investments are valued in accordance with the ‘International Private Equity and Venture Capital Valuation Guidelines’ which require the use of a number of individual pricing benchmarks such as the prices of recent transactions in the same or similar entities, discounted cash flow analysis and comparison with the earnings or revenue multiples of listed companies. While the valuation of unquoted equity instruments is subjective by nature, the relevant methodologies are commonly applied by other market participants and have been consistently applied over time. Observability: Inputs are considered observable if there is active trading in a liquid market of products with significant sensitivity to the inputs. Unobservable inputs include earnings or revenue estimates, multiples of comparative companies, marketability discounts and discount rates. Asset backed securities Description: Securities that are linked to the cash flows of a pool of referenced assets via securitisation. The category includes residential mortgage backed securities, commercial mortgage backed securities, CDOs, collateralised loan obligations (CLOs) and other asset backed securities. Valuation: Where available, valuations are based on observable market prices sourced from broker quotes and inter-dealer prices and external vendor provides who provide pricing. Otherwise, valuations are determined using industry standard discounted cash flow analysis that calculates the fair value based on valuation inputs such as constant default rate, conditional prepayment rate, loss given default and yield. These inputs are determined by reference to a number of sources including proxying to observed transactions, market indices or market research, and by assessing underlying collateral performance. Proxying to observed transactions, indices or research requires an assessment and comparison of the relevant securities’ underlying attributes including collateral, tranche, vintage, underlying asset composition (historical losses, borrower characteristics and loan attributes such as loan to value ratio and geographic concentration) and credit ratings (original and current). Observability: Where an asset backed product does not have an observable market price and the valuation is determined using a discounted cash flow analysis, the instrument is considered unobservable. Government debt Description: Government bonds, supra sovereign bonds and agency bonds. Valuation: Liquid bonds that are actively traded through an exchange or clearing house are marked to the levels observed in these markets. Other actively traded bonds are valued using observable market prices sourced from broker quotes, inter-dealer prices or other reliable pricing sources. Observability: Prices for actively traded bonds are considered observable. Unobservable bonds prices are generally determined by reference to bond yields for actively traded bonds from the same (or a similar) issuer. Issued debt Description: Debt notes issued by Barclays. Valuation: Issued debt is valued using discounted cash flow techniques models incorporating various inputs observed for each instrument. Observability: Barclays issued notes are generally observable. Structured notes are debt instruments containing embedded derivatives. Where either an input to the embedded derivative or the debt instrument is deemed unobservable and significant to the overall valuation of the note, the structured note is classified as Level 3. Other products Description: Other products include funds and fund-linked products, equity cash products, investment property, credit derivatives and foreign exchange derivatives. Assets and liabilities reclassified between Level 1 and Level 2 During the year ended 31 December 2024 , there were no material transfers between Level 1 to Level 2 (year ended 31 December 2023 : there were no material transfers between Level 1 and Level 2). Level 3 movement analysis The following table summarises the movements in the Level 3 balances during the year. Transfers have been reflected as if they had taken place at the beginning of the year. Asset and liability transfers between Level 2 and Level 3 are primarily due to 1) an increase or decrease in observable market activity related to an input or 2) a change in the significance of the unobservable input, with assets and liabilities classified as Level 3 if an unobservable input is deemed significant.

Points are a percentage of par; for example, 100 points equals 100% of par. A basis point equals 1/100 th of 1% ; for example, 150 basis points equals 1.5% . 3 Certain derivative instruments are classified as Level 3 due to a significant unobservable credit spread input into the calculation of the Credit Valuation Adjustment for the instruments. The range of significant unobservable credit spreads is between 14 bps- 1,972 bps ( 2023 : 29 bps- 1,672 bps). 4 Non-material level 3 balances for these unobservable inputs. T he following section describes the significant unobservable inputs identified in the table above, and the sensitivity of fair value measurement of the instruments categorised as Level 3 assets or liabilities to increases in significant unobservable inputs. Where sensitivities are described, the inverse relationship will also generally apply. Where reliable interrelationships can be identified between significant unobservable inputs used in fair value measurement, a description of those interrelationships is included below. Forwards A price or rate that is applicable to a financial transaction that will take place in the future. In general, a significant increase in a forward in isolation will result in a fair value increase for the contracted receiver of the underlying (currency, bond, commodity, etc.), but the sensitivity is dependent on the specific terms of the instrument. Credit spread Credit spreads typically represent the difference in yield between an instrument and a benchmark security or reference rate. Credit spreads reflect the additional yield that a market participant demands for taking on exposure to the credit risk of an instrument and form part of the yield used in a discounted cash flow calculation. In general, a significant increase in credit spread in isolation will result in a fair value decrease for a cash asset. For a derivative instrument, a significant increase in credit spread in isolation can result in a fair value increase or decrease depending on the specific terms of the instrument. Volatility Volatility is a measure of the variability or uncertainty in return for a given derivative underlying. It is an estimate of how much a particular underlying instrument input or index will change in value over time. In general, volatilities are implied from observed option prices. For unobservable options the implied volatility may reflect additional assumptions about the nature of the underlying risk, and the strike/ maturity profile of a specific contract. In general, a significant increase in volatility in isolation will result in a fair value increase for the holder of a simple option, but the sensitivity is dependent on the specific terms of the instrument. There may be interrelationships between unobservable volatilities and other unobservable inputs (e.g. when equity prices fall, implied equity volatilities generally rise) but these are generally specific to individual markets and may vary over time. Correlation Correlation is a measure of the relationship between the movements of two variables. Correlation can be a significant input into valuation of derivative contracts with more than one underlying instrument. Credit correlation generally refers to the correlation between default processes for the separate names that make up the reference pool of a collateralised debt obligation (CDO) structure. A significant increase in correlation in isolation can result in a fair value increase or decrease depending on the specific terms of the instrument. Comparable price Comparable instrument prices are used in valuation by calculating an implied yield (or spread over a liquid benchmark) from the price of a comparable observable instrument, then adjusting that yield (or spread) to account for relevant differences such as maturity or credit quality. Alternatively, a price-to-price basis can be assumed between the comparable and unobservable instruments in order to establish a value. Loans includes a portfolio of loans extended to clients within the Barclays Bank Group’s leveraged finance business. Leveraged finance loans are originated where Barclays Bank Group provides financing commitments to clients to facilitate strategic transactions such as leverage buyouts and acquisitions. The sensitivity of the portfolio to unobservable inputs is judgmental reflecting their illiquid nature and the significance of unobservable price inputs to the valuation. In general, a significant increase in comparable price in isolation will result in an increase in the price of the unobservable instrument. For derivatives, a change in the comparable price in isolation can result in a fair value increase or decrease depending on the specific terms of the instrument. Loan spread Loan spreads typically represent the difference in yield between an instrument and a benchmark security or reference rate. Loan spreads typically reflect credit quality, the level of comparable assets such as gilts and other factors, and form part of the yield used in a discounted cash flow calculation. In general, a significant increase in loan spreads in isolation will result in a fair value decrease for a loan.

Unfavourable changes shown in the table above are partly provided for through the capital and prudential valuation adjustment framework. Fair value adjustments Key balance sheet valuation adjustments are quantified below: 2024 2023 Barclays Bank Group £m £m Exit price adjustments derived from market bid-offer spreads (529) (558) Uncollateralised derivative funding 19 (4) Derivative credit valuation adjustments (184) (209) Derivative debit valuation adjustments 108 144 Exit price adjustments derived from market bid-offer spreads Barclays Bank Group uses mid-market pricing where it is a market maker and has the ability to transact at, or better than, mid-price (which is the case for certain equity, bond and vanilla derivative markets). For other financial assets and liabilities, bid-offer adjustments are recorded to reflect the exit level for the expected close out strategy. The methodology for determining the bid-offer adjustment for a derivative portfolio involves calculating the net risk exposure by offsetting long and short positions by strike and term in accordance with the risk management and hedging strategy. Bid-offer levels are generally derived from market quotes such as broker data. Less liquid instruments may not have a directly observable bid-offer level. In such instances, an exit price adjustment may be derived from an observable bid-offer level for a comparable liquid instrument, or determined by calibrating to derivative prices, or by scenario or historical analysis. Exit price adjustments derived from market bid-offer spreads have decreased by £29m from £ (558) m to £(529)m . Discounting approaches for derivative instruments Collateralised In line with market practice, the methodology for discounting collateralised derivatives takes into account the nature and currency of the collateral that can be posted within the relevant credit support annex (CSA). The CSA aware discounting approach recognises the ‘cheapest to deliver’ option that reflects the ability of the party posting collateral to change the currency of the collateral. Uncollate

Offsetting financial assets and financial liabilities	Offsetting financial assets and financial liabilities The Barclays Bank Group reports financial assets and financial liabilities on a net basis on the balance sheet only if there is a legally enforceable right to set-off the recognised amounts and there is intention to settle on a net basis, or to realise the asset and settle the liability simultaneously. The following table shows the impact of netting arrangements on: ▪ All financial assets and liabilities that are reported net on the balance sheet. ▪ All derivative financial instruments and reverse repurchase and repurchase agreements and other similar secured lending and borrowing agreements that are subject to enforceable master netting arrangements or similar agreements, but do not qualify for balance sheet netting. The ‘Net amounts’ presented in the table below are not intended to represent the Barclays Bank Group’s actual exposure to credit risk, as a variety of credit mitigation strategies are employed in addition to netting and collateral arrangements.

Amounts offset for derivative financial assets additionally includes cash collateral netted of £5,126m ( 2023 : £7,527m ). Amounts offset for derivative financial liabilities additionally includes cash collateral netted of £6,293m ( 2023 : £9,067m ). Settlement assets and liabilities have been offset amounting to £25,133m ( 2023 : £29,297m ). 2. Financial collateral of £41,586m ( 2023 : £39,927m ) was received in respect of derivative assets, including £28,953m ( 2023 : £29,944m ) of cash collateral and £12,633m ( 2023 : £9,983m ) of non-cash collateral. Financial collateral of £27,660m ( 2023 : £27,930m ) was placed in respect of derivative liabilities, including £23,109m ( 2023 : £24,212m ) of cash collateral and £4,551m ( 2023 : £3,718m ) of non-cash collateral. The collateral amounts are limited to net balance sheet exposure so as to not include over-collateralisation. 3. This column includes contractual rights of set-off that are subject to uncertainty under the laws of the relevant jurisdiction. 4. The balance sheet total is the sum of ‘Net amounts reported on the balance sheet’ that are subject to enforceable netting arrangements and ‘Amounts not subject to enforceable netting arrangements’. 5. Reverse repurchase agreements and other similar secured lending of £145,184m ( 2023 : £150,234m ) is split by fair value £141,791m ( 2023 : £149,131m ) and amortised cost £3,393m ( 2023 : £1,103m ). Repurchase agreements and other similar secured borrowing of £185,421m ( 2023 : £215,460m ) is split by fair value £156,024m ( 2023 : £186,906m ) and amortised cost £29,397m ( 2023 : £28,554m ). D erivative assets and liabilities The ‘Financial instruments’ column identifies financial assets and liabilities that are subject to set off under netting agreements, such as the ISDA Master Agreement or derivative exchange or clearing counterparty agreements, whereby all outstanding transactions with the same counterparty can be offset and close-out netting applied across all outstanding transactions covered by the agreements if an event of default or other predetermined events occur. Financial collateral refers to cash and non-cash collateral obtained, typically daily or weekly, to cover the net exposure between counterparties by enabling the collateral to be realised in an event of default or if other predetermined events occur. Reverse repurchase and repurchase agreements and other similar secured lending and borrowing The ‘Financial instruments’ column identifies financial assets and liabilities that are subject to set off under netting agreements, such as Global Master Repurchase Agreements and Global Master Securities Lending Agreements, whereby all outstanding transactions with the same counterparty can be offset and close-out netting applied across all outstanding transactions covered by the agreements if an event of default or other predetermined events occur. Financial collateral typically comprises highly liquid securities which are legally transferred and can be liquidated in the event of counterparty default. These offsetting collateral arrangements and other credit risk mitigation strategies used by the Barclays Bank Group are further explained in the Credit risk management section on page 66 .

Disclosure of detailed information about property, plant and equipment [abstract]
Property, plant and equipment	Property, plant and equipment Accounting for property, plant and equipment Property, plant and equipment is stated at cost, which includes direct and incremental acquisition costs less accumulated depreciation and provisions for impairment, if required. Subsequent costs are capitalised if these result in enhancement of the asset. Depreciation is provided on the depreciable amount of items of property, plant and equipment on a straight-line basis over their estimated useful economic lives. Depreciation rates, methods and the residual values underlying the calculation of depreciation of items of property, plant and equipment are kept under review to take account of any change in circumstances including consideration on future Climate and Sustainability investments. The Barclays Bank Group and Barclays Bank PLC use the following annual rates in calculating depreciation: Annual rates in calculating depreciation Depreciation rate Freehold land Not depreciated Freehold buildings 2% - 3.3% Leasehold property Over the remaining life of the lease Costs of adaptation of freehold and leasehold property 6% - 10% Equipment installed in freehold and leasehold property 6% - 10% Computers and similar equipment 17% - 33% Fixtures and fittings and other equipment 9% - 20% Costs of adaptation and installed equipment are depreciated over the shorter of the life of the lease or the depreciation rates noted in the table above. Investment property The Barclays Bank Group and Barclays Bank PLC initially recognises investment property at cost, and subsequently at fair value at each balance sheet date, reflecting market conditions at the reporting date. Gains and losses on remeasurement are included in the income statement.

Refer to Note 19 for further details. 2 Disposals pertain to fully depreciated assets which are not in use. 3 Exch ange an d other movements in Right of use (ROU) asset balances include modification related to a lease extension by ~ 91 years. Property rentals of £8m ( 2023 : £8 m) have been included in other income within the Barclays Bank Group. The fair value of investment property is determined by reference to current market prices for similar properties, adjusted as necessary for condition and location, or by reference to recent transactions updated to reflect current economic conditions. Discounted cash flow techniques may be employed to calculate fair value where there have been no recent transactions, using current external market inputs such as market rents and interest rates. Valuations are carried out by management with the support of appropriately qualified independent valuers.

Leases

Leases	12 Months Ended

Lease liabilities [abstract]
Leases	Leases Accounting for leases When the Barclays Bank Group or Barclays Bank PLC are the lessee, they are required to recognise both: ▪ a lease liability, measured at the present value of remaining cash flows on the lease ▪ a r ight of use (ROU) asset, measured at the amount of the initial measurement of the lease liability, plus any lease payments made prior to commencement date, initial direct costs, and estimated costs of restoring the underlying asset to the condition required by the lease, less any lease incentives received. Subsequently the lease liability will increase for the accrual of interest, resulting in a constant rate of return throughout the life of the lease, and reduce when payments are made. The right of use asset will amortise to the income statement over the life of the lease. On the balance sheet, the ROU assets are included within property, plant and equipment and the lease liabilities are included within other liabilities . The Barclays Bank Group and Barclays Bank PLC apply the recognition exemption in IFRS 16 for leases with a term not exceeding 12 months. For these leases the lease payments are recognised as an expense on a straight line basis over the lease term unless another systematic basis is more appropriate. When the Barclays Bank Group or Barclays Bank PLC are the lessor, the lease must be classified as either a finance lease or an operating lease. A finance lease is a lease which confers substantially all the risks and rewards of the leased assets on the lessee. An operating lease is a lease where substantially all of the risks and rewards of the leased asset remain with the lessor. As lessors The Barclays Bank Group and Barclays Bank PLC do not have any material operating and finance leases as lessors. As lessees The Barclays Bank Group and Barclays Bank PLC lease various offices, branches and other premises under non-cancellable lease arrangements to meet their operational business requirements. In some instances, the Barclays Bank Group or Barclays Bank PLC will sublease property to third parties when it is no longer needed to meet business requirements. Currently, the Barclays Bank Group and Barclays Bank PLC do not have any material subleasing arrangements. ROU asset balances relate to property leases only. Refer to Note 18 for the carrying amount of ROU assets. The Barclays Bank Group and Barclays Bank PLC have not recognised any expenses related to short term leases during the current and previous year.

Undiscounted lease liabilities maturity analysis Barclays Bank Group 2024 2023 £m £m Not more than one year 70 62 One to two years 66 55 Two to three years 61 49 Three to four years 46 43 Four to five years 40 28 Five to ten years 130 72 Greater than ten years 3,550 16 Total undiscounted lease liabilities as at 31 December 3,963 325 During the year, Barclays had a lease modification for property "New York, 745 7th Avenue" wherein there is an extension of lease term by ~ 91 years , resulting in increase in the above stated undiscounted lease liabilities. In addition to the cash flows identified above, the Barclays Bank Group and Barclays Bank PLC are exposed to: • Variable lease payments: This variability will typically arise from either inflation index instruments or market-based pricing adjustments. Currently, Barclays Bank Group has 38 leases ( 2023 : 49 leases) out of the total 103 leases ( 2023 : 94 leases) which have variable lease payment terms based on market based pricing adjustments. Of the gross cash flows identified above, £3,855m ( 2023 : £229m ) is attributable to leases with some degree of variabili ty predominantly lin ked to market based pricing adjustments. Extension and termination options: The table above represents the Barclays Bank Group’s and the Barclays Bank PLC’s best estimate of future cash outflows for leases, including assumptions regarding the exercising of contractual extension and termination options. The above gross cash flows have been reduced by £9m ( 2023 : £429m ) and £9m ( 2023 : £9m ) respectively for leases where the Barclays Bank Group and the Barclays Bank PLC are highly expected to exercise an early termination option. The above gross cash flows have been increased by £3,638m , of which £1,859m ( 2023 : £ nil ) and £14m ( 2023 : £ nil ) respectively for leases where the Barclays Bank Group and the Barclays Bank PLC are highly expected to exercise an extension option. The Barclays Bank Group and Barclays Bank PLC do not have any restrictions or covenants imposed by the lessor on its property leases which restrict its businesses.

Goodwill and intangible assets

Intangible assets and goodwill [abstract]
Goodwill and intangible assets	Goodwill and intangible assets Accounting for goodwill and intangible assets Goodwill Goodwill arising on the acquisition of subsidiaries represents the excess of the fair value of the purchase consideration over the fair value of the Barclays Bank Group’s share of the assets acquired and the liabilities and contingent liabilities assumed on the date of the acquisition. Goodwill is reviewed annually for impairment, or more frequently when there are indications that impairment may have occurred. The test involves comparing the carrying value of the cash generating unit (CGU) including goodwill with the present value of the pre-tax cash flows, discounted at a rate of interest that reflects the inherent risks, of the CGU to which the goodwill relates, or the CGUs fair value if this is higher. Intangible assets Intangible assets are initially recognised when they are separable or arise from contractual or other legal rights, the cost can be measured reliably and, in the case of intangible assets not acquired in a business combination, where it is probable that future economic benefits attributable to the assets will flow from their use. For internally generated intangible assets, only costs incurred during the development phase are capitalised. Expenditure in the research phase is expensed when it is incurred. Intangible assets are stated at cost (which is, in the case of assets acquired in a business combination, the acquisition date fair value) less accumulated amortisation and provisions for impairment, if any, and are amortised over their useful lives in a manner that reflects the pattern to which they contribute to future cash flows, generally using the amortisation periods set out below: Annual rates in calculating amortisation Amortisation period Goodwill Not amortised Internally generated software 1 12 months to 6 years Other software 12 months to 6 years Customer lists 12 months to 25 years Licences and other 12 months to 25 years Note 1 Exceptions to the above period relate to useful lives of certain core banking platforms that are assessed individually and, if appropriate, amortised over longer periods ranging from 10 years to 15 years . Intangible assets are reviewed for impairment when there are indications that impairment may have occurred. Intangible assets not yet available for use are reviewed annually for impairment.

In 2 024, Goodwill has increased in the year by £ 263 m d ue to the acquisition of Luxury Card's US. Exchange and other movements for the year ended 31 December 2024 includes the reclassification of a co-branded cards portfolio to assets held for sale of £338m and accumulated amortisation of £326m from intangibles to assets held for sale. In 2023, the Barclays Bank Group reclassified assets with a total net book value of £ 412 m recognised on balance sheet relating to sign-on bonus payments made to co-brand credit card partners from Intangible Assets (Licences and other) to Other Assets. This change in classification has been made to more appropriately reflect the nature of the assets. The German Consumer Finance business moved to assets held for sale during 2023 which resulted in an impairment of Intangible assets of £ 32 m. Goodwill Goodwill is allocated to business operations according to business segments as follows: Barclays Bank Group 2024 2023 1 £m £m Barclays Private Bank and Wealth Management 95 95 Barclays US Consumer Bank 444 172 Total net book value of goodwill 539 267 2024 impairment review The 2024 impairment review was performed during Q4 2024 , with the approach and results of this analysis set out below. Determining the carrying value of CGUs The carrying value for each CGU is the sum of the tangible equity, goodwill and intangible asset balances associated with that CGU. The Barclays Bank Group manages the assets and liabilities of its CGUs with reference to the tangible equity of the respective businesses. That tangible equity is derived from the level of risk weighted assets (RWAs) and capital required to be deployed in the CGU and therefore reflects its relative risk, as well as the level of capital that management considers a market participant would be required to hold and retain to support business growth. Goodwill is initially allocated to CGUs or groups of CGUs that are expected to benefit from the synergies of the acquisition that generated it. Goodwill is only reallocated if there is a change in its use or when reporting structures are altered in a way that changes the composition of one or more cash-generating units to which goodwill has been allocated. As a result of the changes in business operating segments announced in the 20 February 2024 Barclays PLC Investor Update the goodwill previously allocated to the Consumer, Cards & Payments CGU has been reallocated to the US Consumer Bank CGU with the 2023 comparatives re-presented. Cash flows The five -year cash flows used in the calculation of value in use are based on the formally agreed medium-term plans approved by the Board. These are prepared using macroeconomic assumptions which management considers reasonable and supportable, and reflect business agreed initiatives for the forecast period. Discount rates IAS 36 requires that the discount rate used in a value in use calculation reflects the pre-tax rate an investor would require if they were to choose an investment that would generate similar cash flows to those that the entity expects to generate from the asset. In determining the discount rate, management identified the cost of equity associated with market participants that closely resemble the Barclays Bank Group's CGUs. The cost of equity has been used as the discount rate in the impairment assessment and applied to the post tax cash flows of the CGU. This post-tax method incorporates the impact of changing tax rates on the cash flows and is expected to produce the same VIU result as a pre-tax method adjusted for varying tax rates. Using the resultant VIU the equivalent pre-tax discount rates have been calculated. The cost of equity rate used for all CGUs in this year’s calculation has been increased to reflect the relative volatility of Barclays PLC ’s stock price versus the average of our peers. The range of equivalent pre-tax discount rates applicable across the CGUs range from 14.5% to 18.5% ( 2023 : 14.7% to 17.2% ). Terminal growth rate The terminal growth rate is used to estimate the effect of projecting cash flows to the end of an asset’s useful economic life. It is management’s judgement that the cash flows associated with the CGUs will grow in line with the major economies in which the Barclays Bank Group operates. The UK inflation rate is used as an approximation for the future growth rates. The terminal growth rate used is 2.0% ( 2023 : 2.0% ). Outcome of goodwill and intangibles review Based on management’s plans an d assumptions the value in use exceeds the carrying value of the CGUs and no goodwill impairment has been indicated by the 2024 impairment review. The CGUs ha ve been aligned to the changes in business operating segments announced in the 20 February 2024 Barclays PLC Investor Update and the 2023 comparatives re-presented .

Interest rate assumptions impact planned cash flows from both customer income and structural hedge contributions and therefore cash flow expectations are highly sensitive to movements in the yield curve. The cash flows also contain assumptions with regard to the prudential and financial conduct regulatory environment which may be subject to change. A sensitivity analysis has been provided to illustrate the impact of a 10% reduction in cash flows. Discount rate: The discount rate should reflect the market risk-free rate adjusted for the inherent risks of the business it is applied to. Management has identified discount rates for comparable businesses and consider these to be a reasonable estimate of a suitable market rate for the profile of the business unit being tested. The risk that these discount rates may not be appropriate is quantified below by showing the impact of a 100bps increase in the discount rate. Terminal growth rate: The terminal growth rate is used to estimate the cash flows into perpetuity based on the expected longevity of the CGU’s businesses. The terminal growth rate is sensitive to uncertainties in the macroeconomic environment. The risk that using inflation data may not be appropriate for its determination is quantified below and shows the impact of a 100 bps decrea se in the terminal growth rate is shown. Allocated capital rate: Tangible equity is allocated based on the level of risk weighted assets (RWAs) and capital required to be deployed in the CGU which is dependent on the relative risk of businesses. The capital ratio used in determining the level of tangible equity allocated to the CGU and its capital cash flows could move over time as a result of a change to the prudential regulatory environment or the risk profile of the business. The impact of a 50bps increase in capital ratio is quantified below. The sensitivity of the value in use to key judgements in the calculations for certain CGUs holding goodwill balances is set out below: Reduction in headroom Change required to reduce headroom to zero Cash generating unit Carrying value Value in use Value in use exceeding carrying value Discount rate Terminal growth rate 100bps increase in the discount rate 100bps decrease in terminal growth rate 50bps increase to allocated capital rate 10% reduction in forecasted cash flows Discount rate Terminal growth rate Allocated Capital rate Cash flows £m £m £m % % £m £m £m £m % % % % Barclays US Consumer Bank 3,636 3,989 353 14.5 2.0 (516) (393) (234) (638) 0.7 (0.9) 0.8 (5.5) Other intangible assets Determining the estimated useful lives of intangible assets (such as those arising from contractual relationships) requires an analysis of circumstances. The assessment of whether an asset is exhibiting indicators of impairment as well as the calculation of impairment, which requires the estimate of future cash flows and fair values less costs to sell, also requires the preparation of cash flow forecasts and fair values for assets that may not be regularly bought and sold.

Provisions [abstract]
Provisions	Provisions Accounting for provisions Provisions are recognised for present obligations arising as consequences of past events where it is more likely than not that a transfer of economic benefit will be necessary to settle the obligation, which can be reliably estimated . Critical accounting estimates and judgements The financial reporting of provisions involves a significant degree of judgement and is complex. Identifying whether a present obligation exists and estimating the probability, timing, nature and quantum of the outflows that may arise from past events requires judgements to be made based on the specific facts and circumstances relating to individual events and often requires specialist professional advice. When matters are at an early stage, accounting judgements and estimates can be difficult because of the high degree of uncertainty involved. Management continues to monitor matters as they develop to re-evaluate on an ongoing basis whether provisions should be recognised, however there can remain a wide range of possible outcomes and uncertainties, particularly in relation to legal, competition and regulatory matters, and as a result it is often not practicable to make meaningful estimates even when matters are at a more advanced stage. The amount that is recognised as a provision can also be very sensitive to the assumptions made in calculating it. This gives rise to a large range of potential outcomes which require judgement in determining an appropriate provision level. See Note 24 for more detail of legal, competition and regulatory matters.

Further analysis of the movement in the expected credit loss provision is disclosed within the 'Movement in gross exposures and impairment allowance including provisions for loan commitments and financial guarantees' table on page 83 to 92 . Provisions expected to be recovered or settled within no more than 12 months after 31 December 2024 for Barclays Bank Group were £663m ( 2023 : £717m ) and for Barclays Bank PLC were £421m ( 2023 : £458m ). Redundancy and restructuring These provisions comprise the estimated cost of restructuring, including redundancy costs where an obligation exists. For example, when the Barclays Bank Group has a detailed formal plan for restructuring a business and has raised valid expectations in those affected by the restructuring by announcing its main features or starting to implement the plan. Customer redress Customer redress provisions comprise the estimated cost of making redress payments to customers, clients and counterparties for losses or damages associated with inappropriate judgement in the execution of the Barclays Bank Group’s business activities. Legal, competition and regulatory matters The Barclays Bank Group is engaged in various legal proceedings, both in the UK and a number of other overseas jurisdictions, including the US. For further information in relation to legal proceedings and discussion of the associated uncertainties, please refer to Note 24. Sundry provisions This category includes provisions that do not fit into any of the other categories, such as fraud losses and dilapidation provisions. Undrawn contractually committed facilities and guarantees Impairment allowance under IFRS 9 considers both the drawn and the undrawn counterparty exposure. For retail portfolios, the total impairment allowance is allocated to the drawn exposure to the extent that the allowance does not exceed the exposure as ECL is not reported separately. Any excess is reported on the liability side of the balance sheet as a provision. For wholesale portfolios the impairment allowance on the undrawn exposure is reported on the liability side of the balance sheet as a provision.

Disclosure of contingent liabilities [abstract]
Contingent liabilities and commitments	Contingent liabilities and commitments Accounting for contingent liabilities Contingent liabilities are possible obligations whose existence will be confirmed only by uncertain future events and present obligations where the transfer of economic resources is uncertain or cannot be reliably measured. Contingent liabilities are not recognised on the balance sheet but are disclosed unless the likelihood of an outflow of economic resources is remote. The following table summarises the nominal principal amount of contingent liabilities and commitments which are not recorded on-balance sheet: Barclays Bank Group 2024 2023 £m £m Guarantees and letters of credit pledged as collateral security 16,814 17,578 Performance guarantees, acceptances and endorsements 9,751 9,251 Total contingent liabilities and financial guarantees 26,565 26,829 Of which: Financial guarantees and letters of credit carried at fair value 988 1,266 Documentary credits and other short-term trade related transactions 1,433 2,352 Standby facilities, credit lines and other commitments 352,344 335,583 Total commitments 1 353,777 337,935 Of which: Loan commitments carried at fair value 15,350 15,203 Expected credit losses held against contingent liabilities and commitments equal £420m ( 2023 : £473m ) for Barclays Bank Group.

Legal proceedings provision [abstract]
Legal, competition and regulatory matters	Legal, competition and regulatory matters The Barclays Bank Group faces legal, competition and regulatory challenges, many of which are beyond our control. The extent of the impact of these matters cannot always be predicted but may materially impact our operations, financial results, condition and prospects. Matters arising from a set of similar circumstances can give rise to either a contingent liability or a provision, or both, depending on the relevant facts and circumstances. The recognition of provisions in relation to such matters involves critical accounting estimates and judgements in accordance with the relevant accounting policies applicable to Note 22, Provisions. We have not disclosed an estimate of the potential financial impact or effect on the Barclays Bank Group of contingent liabilities where it is not currently practicable to do so. Various matters detailed in this note seek damages of an unspecified amount. While certain matters specify the damages claimed, such claimed amounts do not necessarily reflect the Barclays Bank Group’s potential financial exposure in respect of those matters. Investigations into certain advisory services agreements and other proceedings FCA proceedings In 2008, Barclays Bank PLC and Qatar Holdings LLC ent ered in to two advisor y service agreements (the Agreements). The Financial Conduct Authority (FCA) conducted an investigation into whether the Agreements may have related to Barclays PLC’s capital raisings in June and November 2008 (the Capital Raisings) and therefore should have been disclosed in the announcements or public documents relating to the Capital Raisings. In 2013, the FCA issued warning notices (the Warning Notices) finding that Barclays PLC and Barclays Bank PLC acted recklessly and in breach of certain disclosure-related listing rules, and that Barclays PLC was also in breach of Listing Principle 3. The financial penalty provided in the Warning Notices was £ 50 m. Barclays PLC and Barclays Bank PLC contested the findings. In 2022, the FCA’s Regulatory Decisions Committee (RDC) issued decision notices finding that Barclays PLC and Barclays Bank PLC breached certain disclosure-related listing rules. The RDC also found that in relation to the disclosures made in the Capital Raising of November 2008, Barclays PLC and Barclays Bank PLC acted recklessly, and that Barclays PLC breached Listing Principle 3. The RDC upheld the combined penalty of £ 50 m on Barclays PLC and Barclays Bank PLC, the same penalty as in the Warning Notices. Barclays PLC and Barclays Bank PLC referred the RDC’s findings to the Upper Tribunal for reconsideration. In November 2024, Barclays PLC and Barclays Bank PLC withdrew the reference to the Upper Tribunal and agreed a settlement with the FCA for a combined penalty of £ 40 m wit hout accepting the FCA’s findings. This matter is now concluded. Other proceedings In 2023, Barclays Bank PLC received requests for arbitration fr om two Je rsey special purpose vehicles connected to PCP International Finance Limited asserting claims in relation to the October 2008 capital raising. Barclays Bank PLC is defending these claims. Civil actions related to LIBOR and other benchmarks Various individuals and corporates in a range of jurisdictions have threatened or brought civil actions against the Barclays Bank Group and other banks in relation to the alleged manipulation of LIBOR and/or other benchmarks. US civil actions related to LIBOR Multiple civil actions have been filed in the US against the Barclays Bank Group and other banks alleging manipulation of USD LIBOR, Sterling LIBOR and the LIBOR benchmark that was administered by the Intercontinental Exchange Inc. and certain of its affiliates (ICE LIBOR). With respect to USD LIB OR, two actions alleging that Barclays Bank PLC, Barclays Capital Inc. (BCI) and other financial institutions individually and collectively violated provisions of the US Sherman Antitrust Act (Antitrust Act), the US Commodity Exchange Act (CEA), the US Racketeer Influenced and Corrupt Organizations Act (RICO), the US Securities Exchange Act of 1934 and various state laws by manipulating USD LIBOR rates remain pending in the Southern District of New York (SDNY). Both seek unspecified damages. Barclays Bank PLC has moved for summary judgment in these actions, and briefing on that motion was completed in January 2025. Barclays Bank PLC has settled two other actions as serting substantially similar claims in 2023 and 2024. The financial impact of these settlements is not material to the Barclays Bank Group’s operating results, cash flows or financial position. With respect to Sterling LIBOR, consolidated class actions filed in the SDNY against Barclays Bank PLC, BCI and other Sterling LIBOR panel banks alleging, among other things, manipulation of the Sterling LIBOR rate in violation of the Antitrust Act, CEA and RICO, were dismissed in 2018. Oral argument on the plaintiffs’ appeal of that dismissal was heard by the US Court of Appeals for the Second Circuit (Second Circuit) in April 2024. With respect to ICE LIBOR, in August 2020, a group of individual plaintiffs in the US District Court for the Northern District of California on behalf of individual borrowers and consumers of loans and credit cards with variable interest rates linked to USD ICE LIBOR brought an action against Barclays Bank PLC and other financial institutions alleging Antitrust Act violations. The defendants’ motion to dismiss the case was granted in 2022. The US Court of Appeals for the Ninth Circuit affirmed the dismissal in December 2024. Non-US benchmarks civil actions There rem ains one claim , issued in 2017, against Barclays Bank PLC and other banks in the UK in connection with alleged manipulation of LIBOR. Proceedings have also been brought in a number of other jurisdictions in Europe and Israel relating to alleged manipulation of LIBOR and EURIBOR. Foreign exchange civil actions Various individuals and corporates in a range of jurisdictions have threatened or brought civil actions against the Barclays Bank Group and other banks in relation to alleged manipulation of foreign exchange markets. US retail basis civil action In 2015, a putative class action was filed against several international banks, including Barclays PLC and BCI, on behalf of a proposed class of individuals who exchanged currencies on a retail basis at bank branches (Retail Basis Claims). The SDNY has ruled that the Retail Basis Claims are not covered by the settlement agreement in the consolidated FX action. The court subsequently dismissed all Retail Basis Claims against the Barclays Bank Group and all other defendants. The plaintiffs filed an amended complaint. The defendants’ motion for summary judgment was granted in 2023, dismissing the plaintiffs’ remaining claims. The plaintiffs appealed the decision and the dismissal was upheld by the appellate court in May 2024. The plaintiffs’ motion for reconsideration was denied. The plaintiffs did not seek US Supreme Court review and the matter is now concluded. Non-US FX civil actions Legal proceedings have been brought or are threatened against Barclays PLC, Barclays Bank PLC, BCI and Barclays Execution Services Limited (BX) in connection with alleged manipulation of foreign exchange in the UK, a number of other jurisdictions in Europe, Israel, Brazil and Australia. The above-mentioned proceedings include two purporte d class actions filed against Barclays PLC, Barclays Bank PLC, BX, BCI and other financial institutions in the UK Competition Appeal Tribunal (CAT) in 2019. The second class action has now been discontinued. The CAT refused to certify the remaining claim in 2022 and, in 2023, the Court of Appeal overturned the CAT’s decision and found that the claim should be certified on an opt-out basis. Barclays and the other financial institutions involved have obtained permission to appeal this decision to the UK Supreme Court. Metals-related civil actions A US civil complaint alleging manipulation of the price of silver in violation of the CEA, the Antitrust Act and state antitrust and consumer protection laws was brought by a proposed class of plaintiffs against a number of banks, including Barclays Bank PLC, BCI and BX, and transferred to the SDNY. The complaint was dismissed against these Barclays entities and certain other defendants in 2018, and against the remaining defendants in 2023. The plaintiffs have appealed the dismissal of the complaint against all defendants. Civil actions have also been filed in Canadian courts against Barclays PLC, Barclays Bank PLC, Barclays Capital Canada Inc. and BCI on behalf of proposed classes of plaintiffs alleging manipulation of gold and silver prices. US residential mortgage related civil action There rema ins one US Residential Mortgage-Backed Securities (RMBS) related civil action arising from unresolved repurchase requests submitted by Trustees for certain RMBS, alleging breaches of various loan-level representations and warranties (R&Ws) made by Barclays Bank PLC and/or a subsidiary acquired in 2007. Barclays’ motion to dismiss the action was denied in 2023. The parties appealed the decision and, in January 2025, the appellate court reversed the lower court’s decision and dismissed the action. The plaintiff has the right to request review by the New York State Court of Appeals. Government and agency securities civil actions Treasury auction securities civil actions Consolidated putative class action complaints filed in US federal court against Barclays Bank PLC, BCI and other financial institutions under the Antitrust Act and state common law allege that the defendants (i) conspired to manipulate the US Treasury securities market and/or (ii) conspired to prevent the creation of certain platforms by boycotting or threatening to boycott such trading platforms. The court dismissed the consolidated action in 2021. The plaintiffs filed an amended complaint. The defendants’ motion to dismiss the amended complaint was granted in 2022. The plaintiffs appealed this decision, and in February 2024 the appellate court affirmed the dismissal. The plaintiffs did not seek US Supreme Court review, thereby concluding the matter. In addition, certain plaintiffs have filed a related, direct action against BCI and certain other financial institutions, alleging that defendants conspired to fix and manipulate the US Treasury securities market in violation of the Antitrust Act, the CEA and state common law. This action remains stayed. Supranational, Sovereign and Agency bonds civil actions Civil antitrust actions have been filed in the Federal Court of Canada in Toronto against Barclays Bank PLC, BCI, BX, Barclays Capital Securities Limited and Barclays Capital Canada Inc. and other financial institutions alleging that the defendants conspired to fix prices and restrain competition in the market for US dollar-denominated Supranational, Sovereign and Agency bonds. The parties have reached a settlement, which has received final court approval and has been paid. The financial impact of the settlement is not material to the Barclays Bank Group’s operating results, cash flows or financial position. Variable Rate Demand Obligations civil actions Civil actions have been filed against Barclays Bank PLC and BCI and other financial institutions alleging the defendants conspired or colluded to artificially inflate interest rates set for Variable Rate Demand Obligations (VRDOs). VRDOs are municipal bonds with interest rates that reset on a periodic basis, most commonly weekly. An action in state court has been filed by private plaintiffs on behalf of the state of California and the matter is in discov ery. Three putative class action complaints have been consolidated in the SDNY. In the consolidated SDNY class action, certain of the plaintiffs’ claims were dismissed in 2020 and 2022 and the plaintiffs’ motion for class certification was granted in 2023, which means the case may proceed as a class action. The defendants are appealing this decision. Odd-lot corporate bonds antitrust class action In 2020, BCI, together with other financial institutions, were named as defendants in a putative class action in the US. The complaint alleges a conspiracy to boycott developing electronic trading platforms for odd-lots and price fixing. The plaintiffs demand unspecified money damages. The defendants’ motion to dismiss was granted in 2021, which the plaintiffs appealed. In July 2024, the Second Circuit vacated the judgment and remanded the case to the SDNY, where the plaintiffs filed a second amended complaint in September 2024. The defendants have filed a motion to dismiss. Credit Default Swap civil action A putative antitrust class action is pending in New Mexico federal court against Barclays Bank PLC, BCI and various other financial institutions. The plaintiffs, the New Mexico State Investment Council and certain New Mexico pension funds, allege that the defendants conspired to manipulate the benchmark price used to value Credit Default Swap (CDS) contracts at settlement (i.e, the CDS final auction price). The plaintiffs allege violations of US antitrust laws and the CEA, and unjust enrichment under state law. The defendants’ motion to dismiss was denied in 2023. In January 2024, the SDNY ruled that settlement in an earlier CDS antitrust litigation bars these plaintiffs from asserting claims based on conduct occurring before 30 June 2014. The plaintiffs have appealed to the Second Circuit. Interest rate swap and credit default swap US civil actions Barclays PLC, Barclays Bank PLC and BCI, together with other financial institutions that act as market makers for interest rate swaps (IRS), are named as defendants in several antitrust actions, inclu ding one putative clas s action and individual actions brought by certain swap execution facilities, which are consolidated in the SDNY. The complaints allege the defendants conspired to prevent the development of exchanges for IRS and demand unspecified money damages. The parties have reached a settlement of the class action, which received preliminary court approval and has been paid. The financial impact of the settlement is not material to the Barclays Bank Group’s operating results, cash flows or financial position. The individual claims will proceed separately in the SDNY. In 2017, Tera Group Inc. (Tera) filed a separate civil antitrust action in the SDNY claiming that certain conduct alleged in the IRS cases also caused Tera to suffer harm with respect to the Credit Default Swaps market. In 2019, the court dismissed Tera’s claims for unjust enrichment and tortious interference but denied motions to dismiss the antitrust claims. Tera filed an amended complaint in 2020. Barclays’ motion to dismiss all claims was granted in 2023. Tera initially appealed this decision, but in September 2024, Tera declined to pursue its appeal against Barclays. In October 2024, the Second Circuit affirmed the dismissal against the remaining defendants, including Barclays, and the matter is now concluded. BDC Finance L.L.C. In 2008, BDC Finance L.L.C. (BDC) filed a complaint in the Supreme Court of the State of Ne w York, demanding damages of $ 298 m, alleging that Barclays Bank PLC had breached a contract in connection with a portfolio of total return swaps governed by an ISDA Master Agreement (the Master Agreement). Following a trial, the court ruled in 2018 that Barclays Bank PLC was not a defaulting party, which was affirmed on appeal. In 2021, the trial court entered judgment in favour of Barclays Bank PLC for $ 3.3 m and as yet to be determined legal fees and costs. In 2022, the appellate court reversed the trial court’s summary judgment decision in favour of Barclays Bank PLC and remanded the case to the lower court for further proceedings. The parties filed cross-motions on the scope of trial. In January 2024, the court ruled in Barclays’ favour. In December 2024, the appellate court reversed the trial court’s judgment. Civil actions in respect of the US Anti-Terrorism Act Eight civil actions, on behalf of more than 4000 plaintiffs, were filed in US federal courts in the US District Court in the Eastern District of New York (EDNY) and SDNY against Barclays Bank PLC and a number of other banks. The complaints generally allege that Barclays Bank PLC and those banks engaged in a conspiracy to facilitate US dollar-denominated transactions for the Iranian government and various Iranian banks, which in turn funded acts of terrorism that injured or killed the plaintiffs or the plaintiffs’ family members. The plaintiffs seek to recover damages for pain, suffering and mental anguish under the provisions of the US Anti-Terrorism Act, which allow for the trebling of any proven damages. The court granted the defendants’ motions to dismiss three out of the six actions in the EDNY. The plaintiffs appealed in one action and the dismissal was affirmed, and judgment was entered, in 2023. The plaintiffs’ motion to vacate the judgment is fully briefed. The other two dismissed actions in the EDNY were consolidated into one action. The plaintiffs in that action, and in one other action in the EDNY, filed amended complaints in 2023. The two other actions in the EDNY are currently stayed. Out of the two actions in the SDNY, the court granted the defendants’ motion to dismiss the first action. That action is stayed, and the second SDNY action is stayed pending an y appeal on the dismissal of the first. Shareholder derivative action In 2020, a purported Barclays shareholder filed a putative derivative action in New York state court against BCI and a number of current and former members of the Board of Directors of Barclays PLC and senior executives or employees of the Barclays Bank Group. The shareholder plaintiff filed the claim on behalf of nominal defendant Barclays PLC, alleging that the individual defendants harmed the company through breaches of their duties, including under the Companies Act 2006. The plaintiff seeks damages on behalf of Barclays PLC for the losses that Barclays PLC allegedly suffered as a result of these alleged breaches. An amended complaint was filed in 2021, which BCI and certain other defendants moved to dismiss. The motion to dismiss was granted in 2022. The plaintiff appealed the decision, and the dismissal was unanimously affirmed in 2023 by the First Judicial Department in New York. The plaintiff has appealed the First Judicial Department’s decision to the New York Court of Appeals. Derivative transactions civil action In 2021, Vestia, a Dutch housing association, brought a claim against Barclays Bank PLC in the UK High Court in relation to a series of derivative transactions entered into with Barclays Bank PLC between 2008 and 2011, seeking damages of £ 329 m. In May 2024, Barclays Bank PLC reached a settlement whereby Barclays paid € 43.5 m with no acknowledgement of liability. This matter is no w closed. Skilled person review in relation to historic timeshare loans and associated matters Clydesdale Financial Services Limited (CFS), which trades as Barclays Partner Finance and houses Barclays’ point-of-sale finance business, was required by the FCA to undertake a skilled person review in 2020 following concerns about historic affordability assessments for certain loans to customers in connection with timeshare purchases. The skilled person review was concluded in 2021. CFS complied fully with the skilled person review requirements, including carrying out certain remediation measures. CFS was not required to conduct a full back book review. Instead, CFS reviewed limited historic lending to ascertain whether its practices caused customer harm and is remediating any examples of harm. This work was substantially completed during 2023, utilising provisions booked to account for any remediations. The remaining provisions are expected to be utilised during early 2025 . This matter is otherwise concluded. Motor finance commission arrangements In January 2024, the FCA appointe d a skilled person to undertake a review of the historical use of discretionary commission arrangements and sales in the motor finance market across several firms. Barclays is co-operating fully with the FCA’s skilled person review, the outcome of which is unknown. This review follows two final decisions by the UK Financial Ombudsman Service (FOS), including one upholding a complaint against CFS in relation to commission arrangements and disclosure in the sale of motor finance products, and a number of complaints and court claims, including some against CFS. In April 2024, CFS filed a judicial review challenge in the High Court against the FOS’s decision in relation to commission arrangements and disclosure in the sale of motor finance products. In December 2024, the High Court ruled against CFS. CFS has obtained permission to appeal. Separately, in October 2024, the English Court of Appeal issued judgment against the lenders in three motor finance commissions cases. CFS is not a party to this litigation. The Supreme Court has agreed to hear an appeal of these cases, which will tak e place in April 2025. In light of this decision and onward appeal, the FCA has extended its pause on complaints to include all motor finance commissions, not just discretionary commission arrangements. CFS ceased operating in the motor finance market in late 2019. In 2020, CFS was transferred from Barclays Bank PLC to Barclays Principal Investments Ltd (BPIL), another subsidiary of Barclays PLC. Barclays Bank PLC has provided an intragroup indemnity to BPIL in respect of historic litigation and conduct matters relating to CFS. Over-issuance of securities in the US In 2022, executive management became aware that Barclays Bank PLC had issued securities materially in excess of the set amount under its US shelf registration statements. In 2022, a purported class action claim was filed in the US District Court in Manhattan seeking to hold Barclays PLC, Barclays Bank PLC and former and current executives responsible for declines in the price of Barclays PLC’s American depositary receipts, which the plaintiffs claim occurred as a result of alleged misstatements and omissions in its public disclosures. The defendants’ motion to dismiss the case was granted in part and denied in part in February 2024. The parties have reached a settlement in respect of such lawsuit, which has received preliminary court approval and has been paid. The financial impact of this settlement is not material to the Group’s operating results, cash flows or financial position. In addition, holders of a series of ETNs have brought a purported class action in federal court in New York against Barclays PLC, Barclays Bank PLC, and former and current executives and board members in the US alleging, among other things, that Barclays’ failure to disclose that these ETNs were unregistered securities misled investors and that, as a result, Barclays is liable for the holders’ alleged losses following the suspension of further sales and issuances of such series of ETNs. The plaintiffs were granted leave to amend and filed a new complaint in March 2024. Barclays has filed a motion to dismiss. In March 2024, a putative class action was filed in federal court in New York against Barclays PLC, Barclays Bank PLC and former and current executives. The plaintiff purports to bring claims on behalf of a class of short sellers, alleging that their short positions suffered substantial losses when Barclays suspended new issuances and sales of VXX ETNs as a result of the over-issuance of securities. Barclays has filed a motion to dismiss. HM Revenue & Customs (HMRC) assessments concerning UK Value Added Tax In 2018, HMRC issued notices that have the effect of either removing certain Barclays overseas subsidiaries that have operations in the UK from Barclays’ UK VAT group or preventing them from joining it. Supplies between members of a UK VAT group are generally free from VAT. The notices had both retrospective and prospective effect. Barclays appealed HMRC’s decisions to the First-Tier Tribunal (Tax Chamber) in relation to both the retrospective VAT assessments and the on-going VAT payments made since 2018. £ 181 m of VAT (inclusive of interest) was assessed retrospectively by HMRC covering the periods 2014 to 2018, of which approximately £ 128 m is expected to be attributed to Barclays Bank UK PLC and £ 53 m to Barclays Bank PLC. This retrospectively assessed VAT was paid in 2018 and an asset, adjusted to reflect expected eventual recovery, is recognised. Since 2018 Barclays has paid, and recognised as an expense, VAT on intra- group supplies from the relevant subsidiaries to the members of the VAT group. In respect of the ongoing VAT payments, the court upheld HMRC’s denial of the VAT grouping in August 2024. Barclays has appealed t his decision to the Upper Tribunal. FCA investigation conc erning financial crime systems and controls and compliance with the Money Laundering Regulations 2007 The FCA is conducting a civil enforcement investigation into Barclays Bank UK PLC’s and Barclays Bank PLC’s compliance with the Money Laundering Regulations 2007 and the FCA’s Principles of Business and Rules relating to anti-money laundering and financial crime systems and controls. The FCA's investigation focuses primarily on the historical oversight and management of certain customers with heightened risk. Barclays has been cooperating with the investigation. UK bank levy In November 2024, HMRC updated its published guidance on the treatment of beneficiary accounts for the purposes of the exclusion of protected deposits from the UK bank levy charge. HMRC’s interpretation of the UK bank levy legislation differs from Barclays’ interpretation of the legislation, which has been applied in Barclays’ UK bank levy returns and which Barclays continues to consider is correct. In December 2024, HMRC wrote to notify Barclays of its intention to challenge this treatment. Engagement with HMRC is at an early stage and assessments have not yet been issued. General The Barclays Bank Group is engaged in various other legal, competition and regulatory matters in the UK, the US and a number of other overseas jurisdictions. It is subject to legal proceedings brought by and against the Barclays Bank Group which arise in the ordinary course of business from time to time, including (but not limited to) disputes in relation to contracts, securities, guarantees, debt collection, consumer credit, fraud, trusts, client assets, competition, data management and protection, intellectual property, money laundering, financial crime, employment, environmental and other statutory and common law issues. The Barclays Bank Group is also subject to enquiries and examinations, requests for information, audits, investigations and legal and other proceedings by regulators, governmental and other public bodies in connection with (but not limited to) consumer protection measures, measures to combat money laundering and financial crime, compliance with legislation and regulation, wholesale trading activity and other areas of banking and business activities in which the Barclays Bank Group is or has been engaged. The Barclays Bank Group is cooperating with the relevant authorities and keeping all relevant agencies briefed as appropriate in relation to these matters and others described in this note on an ongoing basis. At the present time, the Barclays Bank Group does not expect the ultimate resolution of any of these other matters to have a material adverse effect on its financial position. However, in light of the uncertainties involved in such matters and the matters specifically described in this note, there can be no assurance that the outcome of a particular matter or matters (including formerly active matters or those matters arising after the date of this note) will not be material to Barclays Bank PLC’s results, operations or cash flows for a particular period, depending on, among other things, the amount of the loss resulting from the matter(s) and the amount of profit otherwise reported for the reporting period.

Subordinated liabilities [abstract]
Subordinated liabilities	Subordinated liabilities Accounting for subordinated liabilities Subordinated liabilities are measured at amortised cost using the effective interest method under IFRS 9 , unless they are irrevocably designated at fair value through profit or loss at initial recognition because such designation eliminates or significantly reduces an accounting mismatch.

Dated subordinated liabilities Dated subordinated liabilities are issued by Barclays Bank PLC and its subsidiaries for the development and expansion of their businesses and to strengthen their respective capital bases. The principal terms of the dated subordinated liabilities are described below: Currency and maturity In addition to the individual dated subordinated liabilities listed in the Barclays Bank Group table, the £29,754m ( 2023 : £24,880m ) of intra- group loans is made up of various fixed, fixed to floating rate, floating and zero coupon loans from Barclays PLC with notional amounts denominated in USD 28,275m , EUR 7,230m , GBP 502m , JPY 159,700m , AUD 1,390m , NOK 220m , CAD 450m and CHF 260m , with maturities ranging from 2025 to 2052 . Certain intra-group loans have a call date one year prior to their maturity . Subordination All dated subordinated liabilities, both externally issued and issued intra-group to Barclays PLC, rank behind the claims against Barclays Bank PLC of depositors and other unsecured unsubordinated creditors but before the claims of the undated subordinated liabilities and the holders of Barclays Bank PLC equity. The Barclays Bank PLC intra-group loans from Barclays PLC rank pari passu amongst themselves but ahead of the Barclays Bank PLC notes issued intra-group to Barclays PLC and the Barclays Bank PLC externally issued subordinated liabilities. The external dated subordinated liabilities issued by subsidiaries are similarly subordinated as the external subordinated liabilities issued by Barclays Bank PLC. Interest Interest on floating rate notes and loans is set by reference to market rates at the time of issuance and fixed periodically in advance, based on the related market rates. Interest on fixed rate notes and loans is set by reference to market rates at the time of issuance and fixed until maturity. Interest on fixed rate callable notes and loans is set by reference to market rates at the time of issuance and fixed until the call date or maturity as applicable. After the call date (where relevant), in the event that the notes or loans are not redeemed, the interest rate will be reset to either a fixed or floating rate until maturity based on market rates. No interest is paid on zero coupon notes. Repayment Those subordinated liabilities with a call date are repayable at the option of Barclays Bank PLC on such call date in accordance with the conditions governing the respective debt obligations, some in whole or in part, and some only in whole, or otherwise on maturity. The remaining dated subordinated liabilities outstanding at 31 December 2024 are redeemable only on maturity, subject, in particular cases, to provisions allowing an early redemption in the event of certain changes in tax law or to certain changes in legislation or regulations. Any repayments prior to maturity may require, in the case of Barclays Bank PLC, the prior consent of the PRA or BoE or, in the case of the overseas issues, the consent of the local regulator for that jurisdiction and of the PRA in certain circumstances. There are no committed facilities in existence at the balance sheet date which permit the refinancing of debt beyond the date of maturity.

Preference shares The issued preference share capital of Barclays Bank PLC, as at 31 December 2024 , comprised 31,856 Euro Preference Shares of €100 each ( 2023 : 31,856 ) and 58,133 US Dollar Preference Shares of $100 each ( 2023 : 58,133 ). Ordinary share capital and preference share capital constitutes 100% ( 2023 : 100% ) of total share capital issued. Euro Preference Shares 140,000 Euro non-cumulative callable preference shares of €100 each (the Euro Preference Shares) were issued on 15 March 2005 for a consideration of €1,383.3m ( £966.7m ), of which the nominal value was €14m and the balance was share premium. The Euro Preference Shares entitled the holders thereof to receive Euro non-cumulative cash dividends out of distributable profits of Barclays Bank PLC, annually at a fixed rate of 4.75% per annum on the amount of €10,000 per preference share until 15 March 2020, and since 15 March 2020 quarterly at a rate reset quarterly equal to 0.71% per annum above the Euro interbank offered rate for three-month Euro deposits. The board of directors of Barclays Bank PLC may resolve, in its absolute discretion, not to pay in full, or at all, the dividend on the Euro Preference Shares in respect of a particular dividend period. The Euro Preference Shares are redeemable at the option of Barclays Bank PLC, in whole but not in part only, on each dividend payment date at €10,000 per share plus any dividends accrued for the then current dividend period to the date fixed for redemption. US Dollar Preference Shares 100,000 US Dollar non-cumulative callable preference shares of $100 each (the US Dollar Preference Shares), represented by 100,000 American Depositary Shares, Series 1 , were issued on 8 June 2005 for a consideration of $995.4m ( £548.1m ), of which the nominal value was $10m and the balance was share premium. The US Dollar Preference Shares entitle the holders thereof to receive US Dollar non- cumulative cash dividends out of distributable profits of Barclays Bank PLC, semi-annually at a fixed rate of 6.278% per annum on the amount of $10,000 per preference share until 15 December 2034, and thereafter quarterly at a rate reset quarterly equal to 1.55% per annum above the London interbank offered rate for three-month US Dollar deposits. The board of directors of Barclays Bank PLC may resolve, for any reason and in its absolute discretion, not to declare or pay in full or in part any dividends on the US Dollar Preference Shares in respect of a particular dividend period. The US Dollar Preference Shares are redeemable at the option of Barclays Bank PLC, in whole but not in part only, on 15 December 2034, and on each dividend payment date thereafter at $10,000 per share plus any dividends accrued for the then current dividend period to the date fixed for redemption. No redemption or purchase of any Euro Preference Shares and US Dollar Preference Shares (together, the Preference Shares) may be made by Barclays Bank PLC without the prior consent of the PRA and any such redemption will be subject to the Companies Act 2006 and the Articles of Barclays Bank PLC. On a winding-up of Barclays Bank PLC or other return of capital (other than a redemption or purchase of shares of Barclays Bank PLC, or a reduction of share capital), a holder of Preference Shares will rank in the application of assets of Barclays Bank PLC available to shareholders: (1) junior to the holder of any shares of Barclays Bank PLC in issue ranking in priority to the Preference Shares; (2) equally in all respects with holders of other preference shares and any other shares of Barclays Bank PLC in issue ranking pari passu with the Preference Shares; and (3) in priority to the holders of ordinary shares and any other shares of Barclays Bank PLC in issue ranking junior to the Preference Shares. Subject to such ranking, in such event, holders of the Preference Shares will be entitled to receive out of assets of Barclays Bank PLC available for distributions to shareholders, liquidating distributions in the amount of €10,000 per Euro Preference Share and $10,000 per US Dollar Preference Share, plus, in each case, an amount equal to the accrued dividend for the then current dividend period to the date of the commencement of the winding-up or other such return of capital. If a dividend is not paid in full on any preference shares on any dividend payment date, then a dividend restriction shall apply. This dividend restriction will mean that neither Barclays Bank PLC nor Barclays PLC may (a) declare or pay a dividend (other than payment by Barclays PLC of a final dividend declared by its shareholders prior to the relevant dividend payment date, or a dividend paid by Barclays Bank PLC to Barclays PLC) on any of their respective ordinary shares, other preference shares or other share capital or (b) redeem, purchase, reduce or otherwise acquire any of their respective share capital, other than shares of Barclays Bank PLC held by Barclays PLC or a wholly owned subsidiary, until the earlier of: (1) the date on which Barclays Bank PLC next declares and pays in full a preference share dividend; and (2) the date on or by which all the preference shares are redeemed in full or purchased by Barclays Bank PLC. Holders of the Preference Shares are not entitled to receive notice of, or to attend, or vote at, any general meeting of Barclays Bank PLC. Barclays Bank PLC is not permitted to create a class of shares ranking as regards participation in the profits or assets of Barclays Bank PLC in priority to the preference shares, save with the sanction of a special resolution of a separate general meeting of the holders of the Preference Shares (requiring a majority of not less than three-fourths of the holders of the Preference Shares voting at the separate general meeting) or with the consent in writing of the holders of three-fourths of the Preference Shares. Except as described above, the holders of the Preference Shares have no right to participate in the surplus assets of Barclays Bank PLC. Other equity instrume nts Other equity instruments issued by Barclays Bank PLC of £14,311m ( 2023 : £15,472m ) include AT1 securities issued to Barclays PLC and borrowings of $6bn from a wholly-owned, indirect subsidiary of Barclays Bank PLC. As a result, the other equity instruments balance recorded by Barclays Bank Group is £9,604m ( 2023 : £10,765m ). The borrowings of $6bn from a wholly-owned, indirect subsidiary of Barclays Bank PLC have been recorded as equity since, under their terms, interest payments are non cumulative and discretionary whilst repayment of principal is perpetually deferrable by Barclays Bank PLC. Should Barclays Bank PLC make a discretionary dividend payment on its ordinary shares in the six months preceding the date of an interest payment, it will be obliged to make that interest payment. In 2024 , interest paid on these borrowings was £433m ( 2023 : £439m ). Barclays PLC uses funds from its own market issuance of AT1 securities to purchase AT1 securities from the Barclays Bank Group. The AT1 securities are perpetual securities with no fixed maturity and are structured to qualify as AT1 instruments under prevailing capital rules applicable as at the relevant issue date. In 2024 , there were two issuances of AT1 instruments, in the form of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities, for £970m ( 2023 : three issuances for £2,499m ) which includes issuance costs of £10m ( 2023 : £26m ) .

Classes of employee benefits expense [abstract]
Staff costs	Staff costs Accounting for staff costs Deferred cash and share awards are made to employees to incentivise performance over the period employees provide services. To receive an award, an individual must have provided service over the vesting period and been employed on the scheduled vesting date or be considered an eligible leaver. The expense for deferred cash and share awards is recognised over the period employees’ services contribute to the awards. The Barclays Bank Group considers it appropriate to recognise the expense over the vesting period including the financial year prior to the grant date . The accounting policies for share-based payments and pensions and other post-retirement benefits are included in Note 29 and Note 30 respectively. 2024 2023 2022 £m £m £m Performance costs 1,436 1,308 1,398 Salaries 2,766 2,921 2,637 Social security costs 381 374 352 Post-retirement benefits 1 329 298 188 Other compensation costs 237 221 205 Total compensation costs 2 5,149 5,122 4,780 Other resourcing costs Outsourcing 198 206 259 Redundancy and restructuring 137 176 45 Temporary staff costs 16 22 25 Other 56 65 83 Total other resourcing costs 407 469 412 Total staff costs 5,556 5,591 5,192 Notes 1 Post-retirement benefits charge includes £ 178 m ( 2023 : £180m ; 2022 : £140m ) in respect of defined contribution schemes and £ 151 m ( 2023 : £118m ; 2022 : £48m ) in respect of defined benefit schemes. 2 £324 m ( 2023 : £259m ; 2022 : £197m ) of compensation cost was capitalised as internally generated software.

Share-based payments

Disclosure of terms and conditions of share-based payment arrangement [abstract]
Share-based payments	Share-based payments Accounting for share-based payments Employee incentives include awards in the form of shares and share options, as well as offering employees the opportunity to purchase shares on favourable terms. The cost of the employee services received in respect of the shares or share options granted is recognised in the income statement over the period that employees provide services. The overall cost of the award is calculated using the number of shares and options expected to vest and the fair value of the shares or options at the date of grant. The number of shares and options expected to vest takes into account the likelihood that performance and service conditions included in the terms of the awards will be met. For other share-based payment schemes such as Sharesave and Sharepurchase, there are non-vesting conditions which must be met. Failure to meet the non-vesting condition is treated as a cancellation, resulting in an acceleration of recognition of the cost of the employee services. The fair value of shares is the market price ruling on the grant date, in some cases adjusted to reflect restrictions on transferability. The fair value of options granted is determined using the Black-Scholes model to estimate the numbers of shares likely to vest. The model takes into account the exercise price of the option, the current share price, the risk-free interest rate, the expected volatility of the share price over the life of the option and other relevant factors. Market conditions that must be met in order for the award to vest are also reflected in the fair value of the award, as are any other non-vesting conditions – such as continuing to make payments into a share-based savings scheme. The charge for the year arising from share based payment schemes was as follows: Charge for the year 2024 2023 2022 £m £m £m Share Value Plan and Deferred Share Value Plan 287 254 270 Others 133 144 153 Total equity settled 420 398 423 Cash settled 9 3 3 Total share based payments 429 401 426 The terms of the main current plans are as follows: Share Value Plan (SVP) SVP awards have been granted to participants in the form of a conditional right to receive Barclays PLC shares or provisional allocations of Barclays PLC shares which vest or are considered for release over a period of three, four, five or seven years. Participants do not pay to receive an award or to receive a release of shares. For awards granted before December 2017, the grantor may also make a dividend equivalent payment to participants on release of a SVP award. SVP awards are also made to eligible employees for recruitment purposes. All awards are subject to potential forfeiture in certain leaver scenarios. Deferred Share Value Plan (DSVP) The terms of the DSVP are materially the same as the terms of the SVP as described above, save that Executive Directors are not eligible to participate in the DSVP and the DSVP operates over market purchase shares only. Other schemes In addition to the SVP and DSVP, the Barclays PLC Group operates a number of other schemes settled in Barclays PLC Shares including Sharesave (both UK and Ireland), Sharepurchase (both UK and Overseas), and the Barclays PLC Group Long Term Incentive Plan. A delivery of upfront shares to ‘Material Risk Takers’ can be made as a Share Incentive Award (Holding Period) under the SVP. Share option and award plans The weighted average fair value per award granted, weighted average share price at the date of exercise/release of shares during the year, weighted average contractual remaining life, and number of options and awards outstanding (including those exercisable) at the balance sheet date were as follows: 2024 2023 Weighted average fair value per award granted in year Weighted average share price at exercise/ release during year Weighted average remaining contractual life Number of options/ awards outstanding Weighted average fair value per award granted in year Weighted average share price at exercise/ release during year Weighted average remaining contractual life Number of options/ awards outstanding £ £ in years (000s) £ £ in years (000s) SVP and DSVP 1,2 1.52 1.74 1 441,713 1.49 1.68 1 435,820 Others 1,3 0.81 - 2.1 1.72 - 2.13 0 - 2 43,901 0.31 - 1.69 1.42 - 1.69 0 - 2 51,363 SVP and DSVP are nil cost awards on which the performance conditions are substantially completed at the date of grant. Consequently, the fair value of these awards is based on the market value at that date. Sharesave has a contractual life of 3 years and 5 years, the expected volatility is 30.31% for 3 years and 27.49% for 5 years. The risk free interest rates used for valuations are 4.09% and 3.97% for 3 years and 5 years respectively. The pure dividend yield rates used for valuations are 2.91% and 3.00% for 3 years and 5 years respectively. The repo rates used for valuations are (0.54)% and (0.61)% for 3 years and 5 years respectively. The inputs into the model such as risk free interest rate, expected volatility, pure dividend yield rates and repo rates are derived from market data.

The weighted average exercise price relates to Sharesave. 4 Awards of employees transferred between the Barclays Bank Group and the rest of the Barclays PLC Group. Awards and options granted to employees and former employees of the Barclays Bank Group under the Barclays PLC Group share plans may be satisfied using new issue shares, treasury shares and market purchase shares of Barclays PLC. Awards granted to employees and former employees of the Barclays Bank Group under DSVP may only be satisfied using market purchase shares of Barclays PLC. There were no significant modifications to the share based payments arrangements in 2024 and 2023 . As at 31 December 2024 , the total liability arising from cash-settled share based payments transactions was £10m ( 2023 : £4m ).

Pensions and post-retirement be

Disclosure of defined benefit plans [abstract]
Pensions and post-retirement benefits	Pensions and post-retirement benefits Accounting for pensions and post-retirement benefits The Barclays Bank Group operates a number of pension schemes and post-employment benefit schemes. Defined contribution schemes – the Barclays Bank Group recognises contributions due in respect of the accounting period in the income statement. Any contributions unpaid at the balance sheet date are included as a liability. Defined benefit schemes – the Barclays Bank Group recognises its obligations to members of each scheme at the period end, less the fair value of the scheme assets after applying the asset ceiling test. Each scheme’s obligations are calculated using the projected unit credit method. Scheme assets are stated at fair value as at the period end. Changes in pension scheme liabilities or assets (remeasurements) that do not arise from regular pension cost, net interest on net defined benefit liabilities or assets, past service costs, settlements or contributions to the scheme are recognised in other comprehensive income. Remeasurements comprise experience adjustments (differences between previous actuarial assumptions and what has actually occurred), the effects of changes in actuarial assumptions, return on scheme assets (excluding amounts included in the interest on the assets) and any changes in the effect of the asset ceiling restriction (excluding amounts included in the interest on the restriction). Post-employment benefit schemes – the cost of providing healthcare benefits to retired employees is accrued as a liability in the financial statements over the period that the employees provide services to the Barclays Bank Group, using a methodology similar to that for defined benefit pension schemes. Pension schemes UK Retirement Fund (UKRF) The UKRF is the Barclays Bank Group’s main scheme, representing 96% ( 2023 : 96% ) of the Barclays Bank Group’s total retirement benefit obligations. Barclays Bank PLC is the principal employer of the UKRF. The UKRF was closed to new entrants on 1 October 2012, and comprises 10 sections, the two most significant of which are: ▪ Afterwork, which comprises a contributory cash balance defined benefit element, and a voluntary defined contribution element. The cash balance element is accrued each year and revalued until Normal Retirement Age in line with the increase in Retail Price Index (RPI) (up to a maximum of 5% p.a.). The main risks that the Barclays Bank Group runs in relation to Afterwork are limited although additional contributions are required if pre-retirement investment returns are not sufficient to provide for the benefits. ▪ The 1964 Pension Scheme. Most UK employees recruited before July 1997 built up benefits in this non-contributory defined benefit scheme in respect of service up to 31 March 2010. Pensions were calculated by reference to service and pensionable salary. From 1 April 2010, members became eligible to accrue future service benefits in either Afterwork or the Pension Investment Plan, a historic defined contribution section which is now closed to future contributions. The risks that the Barclays Bank Group runs in relation to the 1964 section are typical of final salary pension schemes, principally that investment returns fall short of expectations, that inflation exceeds expectations, and that retirees live longer than expected. Barclays Pension Savings Plan (BPSP) The BPSP is a defined contribution scheme providing benefits for all new UK hires from 1 October 2012. BPSP is not subject to the same investment return, inflation or life expectancy risks for the Barclays Bank Group that defined benefit schemes are. Members’ benefits reflect contributions paid and the level of investment returns achieved. Other Apart from the UKRF and the BPSP, the Barclays Bank Group operates a number of smaller pension and long-term employee benefits and post-retirement healthcare plans globally, the largest of which are the US defined benefit and defined contribution schemes. Many of the schemes are funded, with assets backing the obligations held in separate legal vehicles such as trusts. Others are operated on an unfunded basis. The benefits provided, the approach to funding, and the legal basis of the schemes, reflect local environments. Governance The UKRF operates under trust law and is managed and administered on behalf of the members in accordance with the terms of the Trust Deed and Rules and all relevant legislation. The Corporate Trustee is Barclays Pension Funds Trustees Limited, a private limited company and a wholly owned subsidiary of Barclays Bank PLC. The Trustee is the legal owner of the assets of the UKRF which are held separately from the assets of the Barclays Bank Group. The Trustee Board comprises six Management Directors selected by Barclays Bank PLC, of whom three are independent Directors with no relationship with the Barclays Bank Group (and who are not members of the UKRF), plus three Member Nominated Directors selected from eligible active, deferred or pensioner members who apply for the role. The BPSP is a Group Personal Pension arrangement which operates as a collection of personal pension plans. Each personal pension plan is a direct contract between the employee and the BPSP provider (Legal & General Assurance Society Limited), and is regulated by the FCA. Similar principles of pension governance apply to the Barclays Bank Group’s other pension schemes, depending on local legislation. Amounts recognised The following tables include amounts recognised in the income statement and an analysis of benefit obligations and scheme assets for all Barclays Bank Group defined benefit schemes. The net position is reconciled to the assets and liabilities recognised on the balance sheet. The tables include funded and unfunded post-retirement benefits. The income statement charge with respect to defined contribution schemes is disclosed as part of footnotes to Note 28 Staff costs. Income statement (credit)/charge 2024 2023 2022 £m £m £m Current service cost 150 119 28 Net finance (income)/cost (157) (222) (122) Past service cost — — 20 Other movements 1 (1) — Total (6) (104) (74) Barclays Bank PLC is the principal employer of the UKRF and hence Scheme Assets and Defined Benefit Obligations relating to the UKRF are recognised within the Barclays Bank Group. Barclays Bank UK PLC and Barclays Execution Services Limited are participating employers in the UKRF and their share of the UKRF service cost is borne by them. Of the £168m current service cost in the table below, £5m relates to Barclays Bank UK PLC and £13m relates to Barclays Execution Services Limited. While the entire current service cost obligation is accounted for in the Barclays Bank Group, the income statement charge is accounted for across all the participating employers.

Barclays has considered the potential implications for the UKRF of the ruling and appeal in Virgin Media v NTL Pension Trustees II Ltd. Activity to date has not identified any relevant amendments to the UKRF (of the nature of that found to have been void in the Virgin Media case) that were not subject to actuarial confirmation. No material additional benefit obligation is expected. As at 31 December 2024 , the UKRF’s scheme assets were in surplus versus IAS 19 obligations by £3,199m ( 2023 : £3,616m ). During 2024, the decrease in the UKRF surplus was driven by changes in market conditions. Defined benefit obligation reduced due to increases in underlying corporate bond yields, however assets reduced by a higher amount. The UKRF’s hedging strategy is more aligned to the funding basis than the accounting basis. The weighted average duration of the benefit payments reflected in the defined benefit obligation for the UKRF is 11 years ( 2023 : 12 years ). The UKRF expected benefits promised to date are projected to be paid out for in excess of 50 years , although 32% of the benefits are expected to be paid in the next 10 years ; 33% in years 11 to 20 and 21% in years 21 to 30 . The remainder of the benefits are expected to be paid beyond 30 years . Of the £1,189m ( 2023 : £1,075m ) UKRF benefits paid out, £165m ( 2023 : £122m ) related to transfers out of the fund. Where a scheme’s assets exceed its obligation, an asset is recognised to the extent that it does not exceed the present value of future contribution holidays or refunds of contributions (the asset ceiling). In the case of the UKRF the asset ceiling is not applied as, in certain specified circumstances such as wind-up, the Barclays Bank Group expects to be able to recover any surplus. Similarly, a liability in respect of future minimum funding requirements is not recognised. The Trustee does not have a substantive right to augment benefits, nor do they have the right to wind-up the plan except in the dissolution of Barclays Bank PLC or termination of contributions by Barclays Bank PLC. The application of the asset ceiling to other plans and recognition of additional liabilities in respect of future minimum funding requirements are considered on an individual plan basis. Critical accounting estimates and judgements Actuarial valuation of the scheme's obligation is dependent upon a series of assumptions. Below is a summary of the main financial and demographic assumptions adopted for the UKRF. Key UKRF financial assumptions 2024 2023 % p.a. % p.a. Discount rate 5.44 4.49 Inflation rate (RPI) 3.32 3.17 The UKRF discount rate assumption for 2024 was based on a standard WTW RATE Link model. The RPI inflation assumption for 2024 was set by reference to the Bank of England’s implied inflation curve. The inflation assumption incorporates a deduction of 20 basis points as an allowance for an inflation risk premium. The methodology used to derive the discount rate and inflation assumptions is consistent with that used at the prior year end. The UKRF’s post-retirement mortality assumptions are based on best estimates derived from an analysis in 2022 of the UKRF’s own post- retirement mortality experience and taking account of recent evidence from published mortality surveys. An allowance has been made for future mortality improvements based on the 2023 core projection model published by the Continuous Mortality Investigation Bureau subject to a long-term trend of 1.25% per annum in future improvements ( 2023 : 1.25% per annum). The table below shows how the assumed life expectancy, for members of the UKRF, has changed since last year: Assumed life expectancy 1 2024 2023 Life expectancy at 60 for current pensioners (years) – Males 26.5 26.5 – Females 29.4 29.3 Life expectancy at 60 for future pensioners currently aged 40 (years) – Males 28.0 28.0 – Females 30.8 30.7 Note: 1 The life expectancies disclosed are in respect of a population of the membership that represent s c 60% of the Defined Benefit Obligation of UKRF (excluding the Afterwork section which has no post-retirement mortality risk) with the remaining members having life expectancy at age 60 of between 26.3 years and 29.4 years . Approximately, 70% of the longevity risk for current pensioners has been reinsured and the transactions will provide income to the UKRF if pensions are paid out for longer than expected. The contracts form part of the UKRF’s investment portfolio. Sensitivity analysis on actuarial assumptions The sensitivity analysis has been calculated by valuing the UKRF liabilities using the amended assumptions shown in the table below and keeping the remaining assumptions the same as disclosed in the table above, except in the case of the inflation sensitivity where other assumptions that depend on assumed inflation have also been amended correspondingly. The difference between the recalculated liability figure and that stated in the balance sheet reconciliation table above is the figure shown. The selection of these movements to illustrate the sensitivity of the defined benefit obligation to key assumptions should not be interpreted as the Barclays Bank Group expressing any specific view of the probability of such movements happening. Change in key assumptions 2024 2023 (Decrease)/Increase in UKRF defined benefit obligation (Decrease)/Increase in UKRF defined benefit obligation £bn £bn Discount rate 0.5% p.a. increase (1.0) (1.2) 0.25% p.a. increase (0.5) (0.6) 0.25% p.a. decrease 0.5 0.6 0.5% p.a. decrease 1.1 1.3 Assumed RPI 0.5% p.a. increase 0.7 0.8 0.25% p.a. increase 0.3 0.4 0.25% p.a. decrease (0.4) (0.4) 0.5% p.a. decrease (0.7) (0.8) Life expectancy at 60 one year increase 0.5 0.6 one year decrease (0.5) (0.6) Assets A long-term investment strategy has been set for the UKRF, with its asset allocation comprising a mixture of gilts, bonds, property and other appropriate assets. This recognises that different asset classes are likely to produce different long-term returns and some asset classes may be more volatile than others. The long-term investment strategy ensures, among other aims, that investments are adequately diversified. The value of the assets of the schemes and their percentage in relation to total scheme assets were as follows: Analysis of scheme assets Barclays Bank Group Total Of which relates to UKRF Quoted Unquoted 1 Value % of total fair value of scheme assets Quoted Unquoted 1 Value % of total fair value of scheme assets £m £m £m % £m £m £m % As at 31 December 2024 Equities 121 — 121 0.5 — — — — Private equities — 2,134 2,134 9.4 — 2,134 2,134 9.7 Bonds - fixed government 1,546 — 1,546 6.8 1,306 — 1,306 6.0 Bonds - index-linked government 8,234 — 8,234 36.4 8,214 — 8,214 37.5 Bonds - corporate and other 5,604 717 6,321 27.9 5,395 717 6,112 27.9 Property 19 1,238 1,257 5.6 — 1,238 1,238 5.6 Infrastructure — 1,388 1,388 6.1 — 1,388 1,388 6.3 Hedge funds 9 1,390 1,399 6.2 — 1,390 1,390 6.3 Derivatives (7) (1,799) (1,806) (8.0) (7) (1,799) (1,806) (8.2) Longevity reinsurance contracts — (117) (117) (0.5) — (117) (117) (0.5) Cash and liquid assets 2 (454) 2,529 2,075 9.2 (464) 2,529 2,065 9.4 Mixed investment funds 8 — 8 — — — — — Other 7 56 63 0.4 — 4 4 — Fair value of scheme assets 15,087 7,536 22,623 100.0 14,444 7,484 21,928 100.0 As at 31 December 2023 Equities 116 — 116 0.5 — — — — Private equities — 2,259 2,259 9.1 — 2,259 2,259 9.3 Bonds - fixed government 1,544 — 1,544 6.2 1,289 — 1,289 5.3 Bonds - index-linked government 9,400 — 9,400 37.7 9,383 — 9,383 38.8 Bonds - corporate and other 6,014 1,237 7,251 29.1 5,818 1,237 7,055 29.1 Property 17 1,197 1,214 4.9 — 1,197 1,197 4.9 Infrastructure 814 720 1,534 6.2 814 720 1,534 6.3 Hedge funds 11 1,309 1,320 5.3 — 1,309 1,309 5.4 Derivatives 25 (1,584) (1,559) (6.3) 25 (1,584) (1,559) (6.4) Longevity reinsurance contracts — (131) (131) (0.5) — (131) (131) (0.5) Cash and liquid assets 2 (1,134) 3,036 1,902 7.6 (1,143) 3,036 1,893 7.8 Mixed Investment funds 12 — 12 — — — — — Other 5 47 52 0.2 — 5 5 — Fair value of scheme assets 16,824 8,090 24,914 100.0 16,186 8,048 24,234 100.0 Notes 1. Valuation of unquoted assets is provided by the underlying managers or qualified independent valuers. The valuation for some of the unquoted assets, in particular private equities, is based on valuations as at 30 September 2024 adjusted by cash flows, these being the latest available valuations as at the point of publication. All valuations are determined in accordance with relevant industry guidance. Barclays Bank Group does not believe these valuations will differ materially from the fair value, in the context of the overall UKRF asset size. 2. Cash and liquid assets for the UKRF consists of £404m ( 2023 : £354m ) cash, £80m ( 2023 : £91m ) receivables/payables, £2,529m ( 2023 : £3,036m ) pooled cash funds and £(948)m ( 2023 : £(1,588)m ) repurchase agreements. Included within the fair value of UKRF scheme assets was nil ( 2023 : nil ) relating to shares in Barclays PLC and nil ( 2023 : nil ) relating to bonds issued by Barclays PLC or Barclays Bank PLC. The UKRF also invests in pooled investment vehicles which may hold shares or debt issued by Barclays PLC. At 31 December 2024 , 38% of the UKRF assets were invested in liability-driven investment strategies; primarily UK gilts as well as interest rate and inflation swaps. These swaps are used to better match the assets to its liabilities. The swaps are used to reduce the scheme’s inflation and duration risks against its liabilities. The UKRF employs derivative instruments, where appropriate, to match assets more closely to liabilities, or to achieve a desired exposure or return. The value of assets shown reflects the assets held by the UKRF, with any derivative holdings reflected on a fair value basis. The UKRF uses repurchase agreements and reverse repurchase agreements to achieve the Trustee’s liability hedging objective. Investment managers are allowed to undertake repo transactions on the UKRF’s existing gilt holdings to raise cash with which to buy additional gilts for efficient portfolio management; and reverse repo transactions to receive gilts and be paid a fee for providing cash. The UKRF has a comprehensive and robust liquidity framework in place. The aim of the liquidity framework is to ensure that pension payments and other liquidity outflows are paid in due course, sufficient liquidity and collateral is maintained to achieve strategic allocation targets and that all liquidity outflows/collateral needs are covered without forced sale or strategic asset allocation changes. The UKRF holds two longevity reinsurance contracts covering 70% of the current pensioner liabilities. The contracts provide income to the UKRF if pensions are paid out for longer than expected. At 31 December 2024 , the combined value of the contracts was £(117)m ( 2023 : £(131)m ). The negative value reflects the estimated impact of changes in the reinsurance market, demographic assumptions and risk premia since the contracts were entered into by the UKRF. For information on the UKRF Trustee’s approach to Responsible Investment and Climate Risk, in the context of managing the UKRF, please refer to the UKRF Trustee website at https://epa.towerswatson.com/accounts/barclays/public/barclays-bank-responsible-investment- policy/. Triennial valuation The UKRF annual funding update as at 30 September 2024 showed a funding surplus of £1.75b n compared to £2.02b n as at 30 September 2023 . The main reasons for the decrease were the impact of investment returns relative to liabilities and benefit accrual exceeding contributions received. The main differences between the funding and accounting assumptions are a different approach to setting the discount rate and a more conservative life expectancy assumption for funding. As part of the 2022 triennial valuation, the Trustee and Barclays Bank PLC agreed an annual adequacy test on a basis more prudent than the IAS 19 or funding bases. Should the UKRF be sufficiently funded on this basis, the regular employer contributions to the UKRF to fund future Afterwork accrual will not be required in the following calendar year. The test will be reviewed at the 2025 triennial valuation. The test was passed in September, so no regular employer contributions are required for 2025 . The next funding valuation of the UKRF is due to be completed in 2026 with an effective date of 30 September 2025 . Other support measures agreed which remain in place Collateral – Barclays Bank PLC has entered into an agreement with the UKRF Trustee to provide collateral to cover at least 100% of any funding deficit with an overall cap of £9b n, to provide security if the UKRF is in a funding deficit. The collateral pool is currently zero reflecting the surplus funding position. The arrangement provides the UKRF Trustee with dedicated access to the pool of assets in the event of Barclays Bank PLC not paying any required deficit reduction contribution to the UKRF or in the event of Barclays Bank PLC’s insolvency. Participation – As permitted under the Financial Services and Markets Act 2000 (Banking Reform) (Pensions) Regulations 2015, currently Barclays Bank UK PLC is a participating employer in the UKRF and will remain so during a transitional phase as set out in a deed of participation. Barclays Bank PLC, a fellow subsidiary of Barclays PLC, is the principal employer of the UKRF. In the event of Barclays Bank PLC’s insolvency during this period, provision has been made to require Barclays Bank UK PLC to become the principal employer of the UKRF. Barclays Bank PLC’s Section 75 debt would be triggered by the insolvency (the debt would be calculated after allowing for the payment to the UKRF of any collateral above). To meet the requirements of the Financial Services and Markets Act 2000 (Banking Reform) (Pensions) Regulations 2015 it is Barclays' intention to sectionalise the UKRF in July 2025, creating two separate sections – the Barclays Bank Section and the Barclays UK Section (with Barclays Bank UK PLC participating in the Barclays UK Section only). This will not change the financial position of the UKRF from a consolidated Barclays PLC Group perspective, and members’ benefits will be unchanged as a result of the actions Barclays is taking to meet its regulatory obligations. Defined benefit contributions paid to the UKRF were £22m ( 2023 : £39m ). There were nil ( 2023 : nil ) Section 75 contributions included within the Barclays Bank Group’s contributions paid as no participating employers left the UKRF in 2024 . The Barclays Bank Group’s expected contribution to the UKRF in respect of defined benefits in 2025 is £4m . In addition, the expected contribution to UK defined contribution schemes in 2025 is £3m to the UKRF an d £67m to the BPSP.

Disclosure of subsidiaries [abstract]
Principal subsidiaries	Principal subsidiaries The significant judgements used in applying this policy are set out below. Accounting for investment in subsidiaries In the individual financial statements of Barclays Bank PLC, investments in subsidiaries are stated at cost less impairment. Investments in subsidiaries, the majority of which are engaged in banking related activities, are recorded on the balance sheet at historical cost less any impairment. At 31 December 2024 the historical cost of investments in subsidiaries was £23,009m ( 2023 : £22,185m ), and impairment allowances recognised against these investments totalled £2,262m ( 2023 : £3,080m ). The increase in the balance sheet value of £1,642m in the year was driven by an increase in the cost of investments in subsidiaries totalling £824m resulting from capital injections and AT1 issuances an d a decrease in impairment of £818m driven by the reversal of £1b n impairment in Barclays Bank Irelan d PLC. During the year, Barclays Bank PLC injected €50 m (2023: €150 m) of additional capital into its subsidiary Barclay s Bank Ireland PLC by way of a subscription for ordinary shares. The capital injection in 2023 was fully impaired during the year ending 31 December 2023. As at the 31 December 2024, the cost of investment in Barclays Bank Ireland PLC is £3,521m being historical cost of £5,140m and accumlated impairment of £1,619m . In May 2023, Barclays Bank PLC acquired the entire issued share capital of Barclays Asset Management Limited and Barclays Investment Solutions Limited, part of the Wealth & Investment Management business, along with certain other assets and liabilities, business guarantees and bu siness contracts (together with the transfer of associated employees of Barclays Bank UK PLC) from Barclays Bank UK PLC. Consideration of £3 was paid by Barclays Bank PLC, which represented the fair value of the transferring businesses. Barclays Bank Group recognised the difference between the carrying value of the net assets acquired and the cash consideration paid directly in equity as a £124 m merger reserve within Other reserves. At the end of each reporting period an impairment review is undertaken in respect of investments in the ordinary shares of subsidiaries. Impairment is indicated where the investment exceeds the recoverable amount. The recoverable amount is calculated as a value in use (VIU) which is derived from the present value of future cash flows expected to be received from the investment. The VIU calculations use forecast profits based on financial budgets approved by management, covering a five-year period as an approximation of future cash flows discounted using a discount rate appropriate to the subsidiary being tested. A terminal growth rate is then applied to the cash flows thereafter, which is based upon expectations of future inflation rates. The 2024 review resulted in the reversal of £1b n of impairment for Barclays Bank Ireland PLC due to an improved performance expectation , the impairment ha d originally been identified as part of the 2022 review. The 2023 review did not result in any change in the 2022 impairment position. Principal subsidiaries of the Barclays Bank Group are set out below. This includes those subsidiaries that are most significant in the context of the Barclays Bank Group’s business, results or financial position. Company Name Principal place of business or incorporation Nature of business Percentage of voting rights held Non-controlling interests - proportion of ownership interests Non-controlling interests - proportion of voting interests % % % Barclays Bank Delaware United States Credit card issuer 100 — — Barclays Bank Ireland PLC Ireland Banking 100 — — Barclays Capital Inc.

Ownership interests are in some cases different to voting interests due to the existence of non-voting equity interests, such as preference shares. Significant judgements and assumptions used to determine the scope of the consolidation Determining whether the Barclays Bank Group has control of an entity is generally straightforward based on ownership of the majority of the voting capital. However, in certain instances, this determination will involve significant judgement, particularly in the case of structured entities where voting rights are often not the determining factor in decisions over the relevant activities. This judgement will involve assessing the purpose and design of the entity. It will also often be necessary to consider whether the Barclays Bank Group, or another involved party with power over the relevant activities, is acting as a principal in its own right or as an agent on behalf of others. There is also often considerable judgement involved in the ongoing assessment of control over structured entities. In this regard, where market conditions have deteriorated such that the other investors’ exposures to the structure’s variable returns have been substantively eliminated, the Barclays Bank Group may conclude that the managers of the structured entity are acting as its agent and therefore will consolidate the structured entity. An interest in equity voting rights exceeding 50% would typically indicate that the Barclays Bank Group has control of an entity. Until 25th October 2024 Palomino Limited was excluded from consolidation despite the Group holding 100% of the voting rights as it was managed by an external counter-party and the Group was not exposed to its variable returns. Following the termination of the management agreement, as from 26th October 2024 the entity is now fully consolidated . Company name Country of registration or incorporation Percentage of voting rights held (%) Equity shareholders' funds (£m) Retained profit for the year (£m) Palomino Limited Cayman Islands 100 — — Interests relating to the entity are included in Note 32 for the year ended 31st December 2023. Significant restrictions As is typical for a group of its size and international scope, there are restrictions on the ability of the Barclays Bank Group to obtain distributions of capital, access the assets or repay the liabilities of certain members of the Barclays Bank Group due to the statutory, regulatory and contractual requirements of its subsidiaries and due to the protective rights of non-controlling interests. These are considered below. Regulatory requirements The Barclays Bank Group’s principal subsidiary companies have assets and liabilities before intercompany eliminations of £515bn ( 2023 : £524bn ) and £490bn ( 2023 : £500bn ) respectively. Certain classes of these assets and liabilities are subject to prudential regulation and regulatory capital requirements in the countries in which the subsidiaries are regulated. These prudential and regulatory capital requirements require entities to maintain minimum capital levels which cannot be returned to the parent company, Barclays Bank PLC, on a going concern basis. In order to meet capital requirements, subsidiaries may issue certain equity accounted and debt accounted financial instruments such as Tier 1 and Tier 2 capital instruments and other forms of subordinated liabilities. Refer to Note 25 and Note 26 for particulars of these instruments. These instruments may be subject to cancellation clauses or preference share restrictions that would limit the ability of the entity to repatriate the capital on a timely basis. Liquidity requirements Regulated subsidiaries of the Barclays Bank Group are required to meet PRA or local regulatory requirements pertaining to liquidity. These regulated subsidiaries include Barclays Capital Securities Limited (which is regulated for liquidity matters on a combined basis with Barclays Bank PLC under a Domestic Liquidity Sub-Group (DoLSub) arrangement), Barclays Bank Ireland PLC, Barclays Capital Inc. and Barclays Bank Delaware Inc. See page 120 for further details of liquidity requirements. Statutory requirements The Barclays Bank Group’s subsidiaries are subject to statutory requirements not to make distributions of capital and unrealised profits and generally to maintain solvency. These requirements restrict the ability of subsidiaries to make remittances of dividends to Barclays Bank PLC, the parent, except in the event of a legal capital reduction or liquidation. In most cases the regulatory restrictions referred to above exceed the statutory restrictions. Asset encumbrance The Barclays Bank Group uses its financial assets to raise finance in the form of securitisations and through the liquidity schemes of central banks, as well as to provide security to the UK Retirement Fund. Once encumbered, the assets are not available for transfer around the Barclays Bank Group. The assets typically affected are disclosed in Note 35. Other restrictions The Barclays Bank Group is required to maintain cash balances with central banks and other regulatory authorities and these amounted to £2,317m ( 2023 : £ 2,973m ) .

Disclosure of information about consolidated structured entities [abstract]
Structured entities	Structured entities A structured entity is an entity in which voting or similar rights are not the dominant factor in deciding who controls the entity. An example is when voting rights may relate to administrative tasks only, with the relevant activities of the entity being directed by means of contractual arrangements. Structured entities are generally created to achieve a narrow and well-defined objective with restrictions around their ongoing activities. Depending on the Barclays Bank Group’s power over the activities of the entity and its exposure to and ability to influence its own returns, it may consolidate the entity. In other cases, it may sponsor or have exposure to such an entity but not consolidate it. Consolidated structured entities The Barclays Bank Group has contractual arrangements which may require it to provide financial support to the following types of consolidated structured entities: ▪ Securitisation vehicles: The Barclays Bank Group uses securitisation as a source of financing and a means of risk transfer. Where entities are controlled by the Barclays Bank Group, they are consolidated. Refer to Note 34 for further detail. ▪ Commercial paper (CP) conduits: These entities issue CP and use the proceeds to lend to clients as part of the Barclays Bank Group's multi-seller conduit programme. The Barclays Bank Group has provided £23.9bn ( 2023 : £22.4bn ) in contractual liquidity facilities to the CP conduits that the Barclays Bank Group consolidates. These amounts represent the maximum the conduits can lend externally. The amounts of CP conduit lending (drawn and undrawn) to unconsolidated structured entities can be seen in 'Other interests in unconsolidated structured entities' under multi-seller conduit programme in the 'Nature of interest' table. ▪ Tender Option Bond (TOB) trusts: During 2024 , the Barclays Bank Group provided undrawn liquidity facilities of £4.0bn ( 2023 : £3.7bn ) to consolidated TOB trusts. These trusts invest in fixed income instruments issued by state, local or other municipalities in the United States, funded by long-term senior floating-rate notes and junior residual securities. Unconsolidated structured entities T he term ‘unconsolidated structured entities’ refers to structured entities not controlled by the Barclays Bank Group, and are established either by Barclays Bank Group or a third party. An interest in a structured entity is any form of contractual or non-contractual involvement which creates variability in returns arising from the performance of the entity for the Barclays Bank Group. Such interests include holdings of debt or equity securities, derivatives that transfer financial risks from the entity to the Barclays Bank Group, lending, loan commitments, financial guarantees and investment management agreements. Barclays Bank Group enters into transactions with unconsolidated structured entities in the normal course of business to facilitate customer transactions, to provide risk management services and for specific investment opportunities. This is predominantly within the Barclays Investment Bank business. Structured entities may take the form of funds, trusts, securitisation vehicles, and private investment companies. The largest transactions for Barclays Bank Group include loans and derivatives with hedge fund structures and special purpose entities, multi-seller conduit lending, holding notes issued by securitisation vehicles and facilitating customer requirements through funds. The nature and extent of the Barclays Bank Group’s interests in structured entities is summarised below: Summary of interests in unconsolidated structured entities Secured financing Short-term traded interests Traded derivatives Other interests Total £m £m £m £m £m As at 31 December 2024 Assets Trading portfolio assets — 23,941 — — 23,941 Financial assets at fair value through the income statement 87,546 — — 1,268 88,814 Derivative financial instruments — — 6,540 — 6,540 Financial assets at fair value through other comprehensive income — — — 4,852 4,852 Loans and advances at amortised cost — — — 46,554 46,554 Debt securities at amortised cost — — — 15,438 15,438 Reverse repurchase agreements and other similar secured lending 3,145 — — — 3,145 Other assets — — — — — Total assets 90,691 23,941 6,540 68,112 189,284 Liabilities Derivative financial instruments — — 6,978 — 6,978 As at 31 December 2023 Assets Trading portfolio assets — 15,482 — — 15,482 Financial assets at fair value through the income statement 74,551 — — 1,099 75,650 Derivative financial instruments — — 5,685 — 5,685 Financial assets at fair value through other comprehensive income — — — 838 838 Loans and advances at amortised cost — — — 34,162 34,162 Debt securities at amortised cost — — — 9,217 9,217 Reverse repurchase agreements and other similar secured lending 896 — — — 896 Other assets — — — 130 130 Total assets 75,447 15,482 5,685 45,446 142,060 Liabilities Derivative financial instruments — — 6,173 — 6,173 Secured financing arrangements, short-term traded interests and traded derivatives are typically managed under Market risk management policies described in the Market risk management section which includes an indication of the change of risk measures compared to last year. For this reason, the total assets of these entities are not considered meaningful for the purposes of understanding the related risks and so have not been presented. Other interests include conduits and lending where the interest is driven by normal customer demand. As at 31 December 2024 , Barclays Bank Group entered into transactions with approximately 5,000 ( 2023 : 6,000 ) structured entities. Secured financing The Barclays Bank Group routinely enters into reverse repurchase contracts, margin lending, stock borrowing and similar arrangements on normal commercial terms where the counterparty to the arrangement is a structured entity. Due to the nature of these arrangements, especially the transfer of collateral and ongoing margining, the Barclays Bank Group is able to manage its variable exposure to the performance of the structured entity counterparty. The counterparties included in secured financing mainly include hedge fund limited structures, investment companies and special purpose entities. Short-term traded interests As part of its market making activities, the Barclays Bank Group buys and sells interests in structured vehicles, which are predominantly debt securities issued by asset securitisation vehicles. Such interests are typically held individually or as part of a larger portfolio for no more than 90 days . In such cases, the Barclays Bank Group typically has no other involvement with the structured entity other than the securities it holds as part of trading activities and its maximum exposure to loss is restricted to the carrying value of the asset. Traded derivatives The Barclays Bank Group enters into a variety of derivative contracts with structured entities which reference market risk variables such as interest rates, equities, foreign exchange rates and credit indices among other things. The main derivative types that are considered interests in structured entities include equity options, index-based and entity specific credit default swaps, and total return swaps. Interest rate swaps and foreign exchange derivatives that are not complex and which expose the Barclays Bank Group to insignificant credit risk by being senior in the payment waterfall of a securitisation and derivatives that are determined to introduce risk or variability to a structured entity are not considered to be an interest in an entity and have been excluded from the disclosures. A description of the types of derivatives and the risk management practices are detailed in Note 13. The risk of loss may be mitigated through ongoing margining requirements as well as a right to cash flows from the structured entity which are senior in the payment waterfall. Such margining requirements are consistent with market practice for many derivative arrangements and in line with the Barclays Bank Group’s normal credit policies. Derivative transactions require the counterparty to provide cash or other collateral under margining agreements to mitigate counterparty credit risk. The Barclays Bank Group is mainly exposed to settlement risk on these derivatives which is mitigated through daily margining. Total notional contract amounts were £712,793m ( 2023 : £335,552m ). Except for credit default swaps where the maximum exposure to loss is the swap notional amount, it is not possible to estimate the maximum exposure to loss in respect of derivative positions as the fair value of derivatives is subject to changes in market rates of interest, exchange rates and credit indices which by their nature are uncertain. In addition, the Barclays Bank Group’s losses would be subject to mitigating action under its traded market risk and credit risk policies that require the counterparty to provide collateral in cash or other assets in most cases. Other interests in unconsolidated structured entities The Barclays Bank Group’s interests in structured entities not held for the purposes of short-term trading activities are set out below, summarised by the nature of the interest and limited to significant categories, based on maximum exposure to loss.

Refer to Note 31 Principal subsidiaries for more details on consolidation. Maximum exposure to loss Unless specified otherwise below, the Barclays Bank Group’s maximum exposure to loss is the total of its on-balance sheet positions and its off-balance sheet arrangements, being loan commitments and financial guarantees. Exposure to loss is mitigated through collateral, financial guarantees, the availability of netting and credit protection held. Multi-seller conduit programme The Barclays Bank Group's multi-seller conduit programme engages in providing financing to various clients and holds whole or partial interests in pools of receivables or similar obligations. These instruments are protected from loss through over-collateralisation, seller guarantees, or other credit enhancements provided to the conduit entity. The Barclays Bank Group’s off-balance sheet exposure included in the table above represents liquidity facilities that are provided to the conduit for the benefit of the holders of the commercial paper issued by the conduit and will only be drawn where the conduit is unable to access the commercial paper market. If these liquidity facilities are drawn, the Barclays Bank Group is protected from loss through over-collateralisation, seller guarantees, or other credit enhancements provided to the conduit. Lending The portfolio includes lending provided by the Barclays Bank Group to unconsolidated structured entities in the normal course of its lending business to earn income in the form of interest and lending fees and includes loans to structured entities that are generally collateralised by property, equipment or other assets. All loans are subject to the Barclays Bank Group’s credit sanctioning process. Collateral arrangements are specific to the circumstances of each loan with additional guarantees and collateral sought from the sponsor of the structured entity for certain arrangements. During the year, the Barclays Bank Group incurred immaterial impairment against such facilities. Other This includes fair value loans with structured entities where the market risk is materially hedged with corresponding derivative contracts, interests in debt securities issued by securitisation vehicles and drawn and undrawn loan facilities to these entities. In addition, 'Other' includes investment funds with interests restricted to management fees based on the performance of the fund and trusts held on behalf of beneficiaries with interests restricted to unpaid fees. Assets transferred to sponsored unconsolidated structured entities The Barclays Bank Group is considered to sponsor another entity if; it had a key role in establishing that entity, it transferred assets to the entity, the Barclays name appears in the name of the entity or it provides guarantees on the entity’s performance. As at 31 December 2024 , assets transferred to sponsored unconsolidated structured entities were £890m ( 2023 : £1,420m ).

Disclosure of transferred financial assets that are not derecognised in their entirety [abstract]
Securitisations	Securitisations Accounting for securitisations The Barclays Bank Group uses securitisations as a source of finance and a means of risk transfer. Such transactions generally result in the transfer of contractual cash flows from portfolios of financial assets to holders of issued debt securities. Securitisations may, depending on the individual arrangement, result in continued recognition of the securitised assets and the recognition of the debt securities issued in the transaction; lead to partial continued recognition of the assets to the extent of the Barclays Bank Group’s continuing involvement in those assets or lead to derecognition of the assets and the separate recognition, as assets or liabilities, of any rights and obligations created or retained in the transfer. Full derecognition only occurs when the Barclays Bank Group transfers both its contractual right to receive cash flows from the financial assets, or retains the contractual rights to receive the cash flows, but assumes a contractual obligation to pay the cash flows to another party without material delay or reinvestment, and also transfers substantially all the risks and rewards of ownership, including credit risk, prepayment risk and interest rate risk. In the course of its normal banking activities, the Barclays Bank Group makes transfers of financial assets, either where legal rights to the cash flows from the asset are passed to the counterparty or beneficially, where the Barclays Bank Group retains the rights to the cash flows but assumes a responsibility to transfer them to the counterparty. Depending on the nature of the transaction, this may result in derecognition of the assets in their entirety, partial derecognition or no derecognition of the assets subject to the transfer. A summary of the main transactions, and the assets and liabilities and the financial risks arising from these transactions, is set out below: Transfers of financial assets that do not result in derecognition Securitisations The Barclays Bank Group is party to securitisation transactions involving its credit card balances, personal and mortgage loans. In these transactions, the assets, interests in the assets, or beneficial interests in the cash flows arising from the assets, are transferred to a special purpose entity, which then issues interest bearing debt securities to third party investors. Securitisations may, depending on the individual arrangement, result in continued recognition of the securitised assets and the recognition of the debt securities issued in the transaction. Partial continued recognition of the assets to the extent of the Barclays Bank Group’s continuing involvement in those assets can also occur or derecognition of the assets and the separate recognition, as assets or liabilities, of any rights and obligations created or retained in the transfer. The following table shows the carrying amount of securitised assets that have not resulted in full derecognition, together with the associated liabilities, for each category of asset on the balance sheet: 2024 2023 Assets Liabilities Assets Liabilities Carrying amount Fair value Carrying amount Fair value Carrying amount Fair value Carrying amount Fair value £m £m £m £m £m £m £m £m Barclays Bank Group Loans and advances at amortised cost Credit cards, unsecured loans and other retail lending 6,575 7,158 (1,575) (1,579) 6,317 6,863 (2,336) (2,303) Financial assets at FVTPL Mortgage Loans 576 576 — — 452 452 — — Assets included in disposal groups classified as held for sale Personal Loans 846 826 — — — — — — Total 7,997 8,560 (1,575) (1,579) 6,769 7,315 (2,336) (2,303) Balances included within loans and advances at amortised cost represent securitisations where substantially all the risks and rewards of the assets have been retained by Barclays Bank Group and balances included within Financial assets at FVTPL and Assets included in disposal groups classified as held for sale represent securitisations where the risks and rewards are neither substantially transferred nor retained. The relationship between the transferred assets and the associated liabilities is that holders of notes may only look to cash flows from the securitised assets for payments of principal and interest due to them under the terms of their notes, although the contractual terms of their notes may be different to the maturity and interest of the transferred assets. If the Barclays Bank Group transfers a financial asset but does not transfer or retain substantially all the risk and rewards of the asset and retains control over it, the transferred assets are recognised to the extent of Barclays Bank Group's continuing involvement. Total Financial assets of £11,951m ( 2023 : £3,353m ) were originally tran sferred in this manner and the carrying value of the assets representing continued involvement is included in the table above. For transfers of assets in relation to repurchase agreements, see Note 35. Continuing involvement in financial assets that have been derecognised In some cases, the Barclays Bank Group may have transferred a financial asset in its entirety but may have continuing involvement in it. This arises in asset securitisations where loans and asset backed securities were derecognised as a result of the Barclays Bank Group’s involvement with asset backed securities, residential mortgage backed securities and commercial mortgage backed securities. Continuing involvement largely arises from providing financing into these structures in the form of retained notes, which do not bear first losses. The table below shows the potential financial implications of such continuing involvement: Continuing involvement 1 Gain from continuing involvement Carrying amount Fair value Maximum exposure to loss 2 For the year ended Cumulative to 31 December Type of transfer £m £m £m £m £m 2024 Asset backed securities 53 53 130 1 1 Residential mortgage backed securities 3,439 3,437 3,439 155 231 Commercial mortgage backed securities 377 334 377 3 21 Total 3,869 3,824 3,946 159 253 2023 Asset backed securities 2 2 2 — 3 Residential mortgage backed securities 1,158 1,156 1,158 57 75 Commercial mortgage backed securities 392 341 392 3 19 Total 1,552 1,499 1,552 60 97 Notes 1 Assets which represent the Barclays Bank Group’s continuing involvement in derecognised assets are recorded in Loans and advances at amortised cost and Debt securities at FVTPL. 2 Maximum exposure to loss includes notional value of undrawn loan commitment, if any.

Assets Pledged, Collateral Received And Assets Transferred [Abstract]
Assets pledged, collateral received and assets transferred	Assets pledged, collateral received and assets transferred Assets are pledged or transferred as collateral to secure liabilities under repurchase agreements, securitisations and stock lending agreements or as security deposits relating to derivatives. Assets transferred are non-cash assets transferred to a third party that do not qualify for derecognition from the Barclays Bank Group’s balance sheet, for example because the Barclays Bank Group retains substantially all the exposure to those assets under an agreement to repurchase them in the future for a fixed price. Where non-cash assets are pledged or transferred as collateral for cash received, the asset continues to be recognised in full, and a related liability is also recognised on the balance sheet. Where non-cash assets are pledged or transferred as collateral in an exchange for non-cash assets, the transferred asset continues to be recognised in full, and there is no associated liability as the non-cash collateral received is not recognised on the balance sheet. The Barclays Bank Group is unable to use, sell or pledge the transferred assets for the duration of the transaction and remains exposed to interest rate risk and credit risk on these pledged assets. Unless stated, the counterparty's recourse is not limited to the transferred assets. Collateralised transactions, such as securities lending and borrowing, repurchase and derivative transactions are conducted in accordance with standard terms which are customary in the market. The following table summarises the nature and carrying amount of the assets pledged as security: Barclays Bank Group 2024 2023 £m £m Cash collateral 72,415 70,007 Loans and advances at amortised cost 41,205 46,902 Trading portfolio assets 107,249 117,696 Financial assets at fair value through the income statement 5,729 9,847 Financial assets at fair value through other comprehensive income 20,420 24,118 Assets pledged 247,018 268,570 The following table summarises the transferred financial assets and the associated liabilities.

Non-current assets or disposal groups classified as held for sale or as held for distribution to owners [abstract]
Assets and liabilities included in disposal group classified as held for sale	Assets and liabilities included in disposal group classified as held for sale Accounting for non-current assets held for sale and associated liabilities The Barclays Bank Group applies IFRS 5 Non-current Assets Held for Sale and Discontinued Operations. Non-current assets (or disposal groups) are classified as held for sale when their carrying amount is to be recovered principally through a sale transaction rather than continuing use. In order to be classified as held for sale, the asset must be available for immediate sale in its present condition subject only to terms that are usual and customary, and the sale must be highly probable. Non-current assets (or disposal groups) held for sale are measured at the lower of carrying amount and fair value less cost to sell. Assets and liabilities classified as held for sale are presented separately in the consolidated balance sheet. Management judgement is required in determining whether the IFRS 5 held for sale classification criteria are met, in particular whether the sale is highly probable and expected to qualify for recognition as a completed sale within 12 months of classification. This assessment requires consideration of how committed management is to the sales plan, the likelihood of obtaining regulatory or other external approvals which is often required for sales of banking operations and how committed the buyer is to complete the sales transaction within the agreed timelines. Barclays Bank Ireland PLC agreed the sale of its German consumer finance business (comprising credit cards, unsecured personal loans and deposits), currently within Head Office. Barclays has recorded a £9 m loss for the disposal group within Head Office for FY24. After the balance sheet date, Barclays announced it had completed the sale as part of our ambition to simplify Barclays and support our focus our key businesses. Barclays has decided not to bid to become the sole issuer for a co-branded card portfolio in USCB, leading to its transfer in H1 2026. This portfolio held within USCB is expected to be sold at a premium. The extension to the 1 year sale period is aligned to the signed contractual arrangements in place to allow the transition of the portfolio in a controlled and effective manner. The perimeter of the disposal group has been accounted for in line with the requirements of IFRS5 as at 31 December 2024. A detailed analysis of the disposal group is presented below. The 2024 disposal group includes the German Consumer Finance Business within Head Office and the US Cards portfolio within USCB. The 2023 Disposal Group includes the German Consumer Finance Business: As at 31 December 2024 2023 £m £m Assets included in disposal groups classified as held for sale Loans and advances to customers 9,544 3,855 Intangible assets 25 15 Property, plant and equipment 24 24 Other assets 260 22 Total assets classified as held for sale 9,854 3,916 Liabilities included in disposal groups classified as held for sale Deposits from customers 3,647 3,077 Other liabilities 77 83 Provisions 2 4 Total liabilities classified as held for sale 3,726 3,164 Net assets classified as held for sale 6,128 752

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	As detailed below, Barclays' Chief Security Office and Chief Information Security Office operate controls aimed at mitigating cybersecurity- related risks and understanding internal and external threats. Barclays deploys controls designed to protect its sensitive information and the data that has been entrusted to us by customers and clients, in line with our Standards, taking into account findings from internal and external reviews of our controls. Barclays seeks to protect the security of data we share with third parties, including by conducting remote and on-site inspections with certain suppliers to review their controls against contractual obligations and industry standards. A Third Party Service Provider Framework is in place which sets out control requirements for business units to manage the operational, reputational, conduct and legal risks to Barclays through its supply chain. In operating under a hybrid working model, we have continued to educate colleagues on cybersecurity risks in order to help minimise risks related to remote working, such as data exploitation or leakage. Barclays works with industry bodies and cybersecurity vendors to learn from risk events in other organisations. Our teams use such intelligence to simulate plausible cybersecurity and data compromise scenarios that allow us to exercise, review and improve our response and recovery plans in preparation for evolving threats. Operational resilience Customers and clients have increased expectations for us to be ‘Always On’. The interconnectivity of the financial sector means the stability and resilience of our systems, workforce and the continued provision of third party services, all have a direct impact on the quality of our service. Resilience and security is a focus for the Board. Barclays continues to strengthen its resilience posture and is focused on its ability to recover from a range of ‘severe but plausible’ scenarios which could cause detriment to its customers and clients and the broader financial market. To enable this, we define Groupwide business services and their interdependencies across the Group, including technology, third party services and our workforce. Recovery plans and business response plans have been developed for a range of different disruption events, such as cyber or data integrity disruptions, or technology failures. These recovery plans are reviewed and validated through regular testing which supports our aim to reduce the volume and impact of operational incidents year on year. We also conduct regular assurance on third parties to assess their capability. Operational resilience is delivered through an established and robust Operational Resilience Framework underpinned by a Policy, Standards, methodologies and procedures. These are integrated with Barclays’ Enterprise Risk Management Framework (ERMF) and set the tone from the top. The Standards are embedded within the Barclays Controls Framework and provide a consistent approach across the firm. The Operational Recovery Planning Policy and Standards drive the identification of the business services that are most important to Barclays, its customers, clients and the markets in which Barclays operates. The Standards also define requirements for setting recovery targets, mapping of dependencies, planning and testing. Resilience and security is the responsibility of everyone within the Group. All permanent employees are required to complete annual mandatory training on these topics. Engaging external security consultants to conduct penetration tests, attack simulations and other reviews to independently benchmark Barclays’ cybersecurity capabilities is an important part of our cybersecurity programme that allows us to identify and remediate cybersecurity weaknesses. In 2024, Barclays’ Group CISO and Group Chief Information Officer briefed the Board Risk Committee on plans to address the findings of penetration testing and cybersecurity assessments and remediate identified weaknesses. Barclays also partners with third party security providers on certain activities such as cyber recovery, software vulnerability scanning, penetration testing, distributed denial of service (DDoS) attack prevention, phishing simulations, third party risk management, incident response, intelligence, fraud prevention, and industry benchmarking. An important part of Barclays’ cybersecurity environment is its Joint Operations Centres (JOCs), which operate 24x7x365 from three globally strategic locations, linking Barclays’ security professionals and incident response managers with control functions and business unit representatives. The JOCs deliver security responsiveness by uniting core security functions and providing a central information and coordination point for security incident management and escalation, based on defined severity levels. During live incidents, the Barclays Crisis Management Team monitors the response by Incident Management Teams, Resilience Leads, and others, and has discretion to invoke one or more Barclays Crisis Leadership Teams (CLTs). CLTs are business-led teams at entity, business unit, and regional levels that provide strategic leadership in a crisis, maintain incident management oversight, and coordinate key decision making. To manage security risk from Barclays’ third party suppliers, many of which perform critical services for Barclays businesses and handle sensitive Barclays data, we have a set of contractual Information and Cyber Security Supplier Control Obligations that are based on requirements in our internal Standards. Using our dedicated Third Party Security Management team’s capabilities, as well as third party tooling, we conduct assurance over our third and fourth parties against those obligations. Activity is structured on a risk-based approach that prioritises suppliers that underpin our most important business services. Identified issues are managed formally, but we also engage proactively with third party suppliers to help them strengthen their security and resilience posture. To recognise the risk presented by third party suppliers, which are increasingly targeted by threat actors, we regularly alert third party suppliers where we anticipate that they may be more vulnerable and should take preventative action. Notwithstanding such third party risk management efforts, Barclays does not have direct control over the cybersecurity of the systems of its third and fourth parties, limiting the Group’s ability to effectively protect and defend against certain threats. Certifications Barclays holds three ISO27001 certifications (i.e. the international standard on how to manage information security), Cyber Essentials / Cyber Essentials Plus Certification, and a UK certification for Digital Banking. Training Barclays requires colleagues to complete mandatory information security training at least annually. Topics covered include incident reporting procedures, protecting sensitive data, device security, data leakage prevention, social engineering awareness, and password management. Consequences of noncompletion may include disciplinary action and impact to compensation. Barclays performs a number of key activities related to identifying, investigating, responding to and containing phishing, including an operational process that provides education and awareness through phishing simulation exercises, and management interventions for employees who demonstrate susceptibility to phishing lures. To report suspected phishing to Barclays' JOCs for further investigation, colleagues have a reporting tool integrated into their email account and receive feedback on whether the reported email was suspect or genuine. Barclays uses metrics to continually refine its phishing education and training.

They support Barclays' ability to operate in a protected and secure environment, and actively promote a culture of security as everyone's responsibility. The Group Chief Security Officer and Group Chief Information Security Officer (CISO) head Barclays' Chief Security Office and Chief Information Security Office, respectively. The Group Chief Security Office is responsible for physical security, threat intelligence, crisis management, and investigations and liaising with law enforcement, among other areas. Barclays' Group Chief Security Officer combines 10 years of law enforcement experience with over 20 years of experience in senior leadership roles managing security at global financial institutions, and is supported by a leadership team with expertise in threat intelligence, investigations, security transformation, and crisis management, as well as other teams of subject matter experts and analysts. In 2024, Barclays’ Group CISO was elevated to report directly to the Group Chief Information Officer (a member of the Group Executive Committee), to leverage the strategic and operational benefits of aligning cybersecurity and technology. The Group Chief Information Officer reports to the Chief Operating Officer, and also sits on the Group Executive Committe e. Barclays’ Group CISO is responsible for assessing and managing Barclays’ material risks from cybersecurity threats. The Group CISO is responsible for areas that, among others, include cybersecurity operations; internal penetration testing; third party security management; cryptography; vulnerability management; governance, risk, and compliance; cyber threat intelligence; and identity access management . The Group CISO has more than 20 years of experience managing cybersecurity for global financial institutions, including responsibility for cybersecurity fusion centres, cyber intelligence, security engineering and architecture, security operations, and network services. The Group CISO is supported by a team of CISOs for individual business units and jurisdictions. Chief Information Security Office leaders manage Barclays’ cybersecurity activities and are accountable for the day-to-day monitoring of residual risk, identification of gaps, oversight of remedial actions and implementation of strategy. The Group CISO and supporting leadership team collectively have advanced degrees and senior level experience managing cybersecurity risks in a variety of sectors, including those that represent critical national infrastructure, such as telecommunications and financial institutions. They are supported by teams of subject matter experts and analysts in a variety of specialisations, such as penetration testing, cyber-forensic investigations, security engineering, and vulnerability management. Supporting the delivery of Barclays’ cyber and information security strategy are multiple management committees, forums, and councils, including Cyber Control Councils for each of the eleven Standards supporting the Group Information and Cybersecurity Policy. These Cyber Control Standards Councils feed into the Cybersecurity Horizontal Controls Forum, the Group Controls Committee, the Group Risk Committee, and ultimately the Board Risk Committee. In addition, the Group COO holds standalone business reviews that include management updates on the status of cybersecurity across the Group, and a standalone COO Controls Forum that also escalates to the Group Controls Committee. Barclays’ Operational Risk and Internal Audit functions provide independent views of cyber risk management from second and third line of defence perspectives. Barclays assesses its cybersecurity activities against the industry-recognised National Institute of Standards and Technology (NIST) Cybersecurity Framework. Under Barclays' Enterprise Risk Management Framework, there is an Information and Cyber Security Policy supported by eleven Standards which define the minimum requirements for cybersecurity matters across the Barclays Group. The Policy leverages key risk indicators defined in the Standards to integrate cybersecurity risk management into the Group’s Enterprise Risk Management Framework. The Standards cover the following topics: Cryptography, Network Security, Security Configuration, Data Loss Prevention, Vulnerability Management, Data Security, Incident Response & Threat Intelligence, Threat Management, Governance, Identity & Access Management, and Application Security. The Group CISO approves and is accountable for the Information and Cyber Security Policy and associated Standards. As part of our programme, we periodically assess our performance against these Standards and identify areas for improvement and remediation. The Board Risk Committee, within its oversight of Operational Risk as a Principal Risk, is responsible for overseeing risks arising from cybersecurity threats. In 2024, the Group Chief Security Officer and Group CISO provided updates to the Board Risk Committee about cybersecurity risks facing the Group. Such updates addressed topics that included the cybersecurity threat environment and ransomware attack preparedness, measurement of Barclays' risk and control posture, cybersecurity incident trends and Barclays' response, plans to improve Barclays' ability to recover from a material cyberattack scenario, Barclays’ vulnerability management, privileged access to Barclays' systems, regulatory developments, and risks and opportunities related to emerging technology and artificial intelligence.

Disclosure of objectives, policies and processes for managing capital [abstract]
Compliance with International Financial Reporting Standards	Compliance with International Financial Reporting Standards The consolidated financial statements of the Barclays Bank Group, and the separate financial statements of Barclays Bank PLC, have been prepared in accordance with UK-adopted international accounting standards. The consolidated financial statements of the Barclays Bank Group, and the separate financial statements of Barclays Bank PLC, have also been prepared in accordance with (1) International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB), including interpretations issued by the IFRS Interpretations Committee, as there are no applicable differences from IFRS as issued by the IASB for the periods presented; and (2) IFRS adopted pursuant to Regulation (EC) No. 1606/2002 as it applies in the European Union (“IFRS as adopted by the EU”). There are currently no differences between UK-adopted international accounting standards and IFRS as adopted by the EU and therefore no reconciliation of variances is provided. The principal accounting policies applied in the preparation of the consolidated and separate financial statements are set out below, and in the relevant notes to the financial statements. These policies have been consistently applied, with the exception of Classification of Liabilities as Current or Non-current (Amendments to IAS 1), which was effective from 1 January 2024 and applies retrospectively.
Basis of preparation	Basis of preparation The consolidated and separate financial statements have been prepared under the historical cost convention modified to include the fair valuation of investment property, and particular financial instruments, to the extent required or permitted under IFRS as set out in the relevant accounting policies. The financial statements are stated in millions of Pounds Sterling (£m), the functional currency of Barclays Bank PLC. The financial statements have been prepared on a going concern basis, in accordance with the Companies Act 2006 as applicable to companies using IFRS. The financial statements are prepared on a going concern basis as the Board is satisfied that the Barclays Bank Group and parent company have the resources to continue in business for a period of at least 12 months from approval of the financial statements. In making this assessment, the Board has considered a wide range of information relating to present and future conditions and has reviewed a working capital report (WCR). The WCR is used by the Board to assess the future performance of the Barclays Bank Group and whether it has the resources in place that are required to meet its ongoing regulatory requirements. The WCR assessment is based upon business plans which contain future forecasts of profitability taken from the Barclays Bank Group’s medium term plan as well as projections of regulatory capital requirements and business funding needs. The WCR also includes an assessment of the impact of internally generated stress testing scenarios on the liquidity and capital requirement forecasts. The stress tests used were based upon an assessment of reasonably possible downside economic scenarios that the Barclays Bank Group could experience. The WCR showed that the Barclays Bank Group had sufficient capital and liquidity in place to support its future business requirements and remained above its regulatory minimum requirements in the stress scenarios. Accordingly, the Board concluded that there was a reasonable expectation that the Barclays Bank Group has adequate resources to continue as a going concern for a period of at least 12 months from the date of approval of the financial statements.
Consolidation	Consolidation The consolidated financial statements combine the financial statements of Barclays Bank PLC and all its subsidiaries. Subsidiaries are entities over which Barclays Bank PLC has control. The Barclays Bank Group has control over another entity when the Barclays Bank Group has all of the following: 1) power over the relevant activities of the investee, for example through voting or other rights; 2) exposure to, or rights to, variable returns from its involvement with the investee; and 3) the ability to affect those returns through its power over the investee. As the consolidated financial statements include partnerships where the Barclays Bank Group member is a partner, advantage has been taken of the exemption under Regulation 7 of the Partnership (Accounts) Regulations 2008 with regard to preparing and filing of individual partnership financial statements. Details of the principal subsidiaries are given in Note 31.
Foreign currency translation	Foreign currency translation Transactions in foreign currencies are translated into Sterling at the rate ruling on the date of the transaction. Foreign currency monetary balances are translated into Sterling at the period end exchange rates. Exchange gains and losses on such balances are taken to the income statement. The Barclays Bank Group’s foreign operations (including subsidiaries, joint ventures, associates and branches) based mainly outside the UK may have different functional currencies. The functional currency of an operation is the currency of the main economy to which it is exposed. Prior to consolidation (or equity accounting) the assets and liabilities of non-Sterling operations are translated at the period end exchange rate and items of income, expense and other comprehensive income are translated into Sterling at the rate on the date of the transactions. Exchange differences arising on the translation of foreign operations are included in currency translation reserves within equity. These are transferred to the income statement when the Barclays Bank Group disposes of the entire interest in a foreign operation, when partial disposal results in the loss of control of an interest in a subsidiary, when an investment previously accounted for using the equity method is accounted for as a financial asset, or on the disposal of a foreign operation within a branch.
Financial assets and liabilities	Financial assets and liabilities Recognition The Barclays Bank Group recognises financial assets and liabilities when it becomes a party to the terms of the contract. Trade date or settlement date accounting is applied depending on the classification of the financial asset. Classification and measurement Financial assets are classified on the basis of two criteria: i) the business model within which financial assets are managed; and ii) their contractual cash flow characteristics (whether the cash flows represent ‘solely payments of principal and interest’ (SPPI)). The Barclays Bank Group assesses the business model criteria at a portfolio level. Information that is considered in determining the applicable business model includes (i) policies and objectives for the relevant portfolio, (ii) how the performance and risks of the portfolio are managed, evaluated and reported to management, and (iii) the frequency, volume and timing of sales in prior periods, sales expectation for future periods, and the reasons for such sales. The contractual cash flow characteristics of financial assets are assessed with reference to whether the cash flows represent SPPI. Terms that could change the contractual cash flows so that it would not meet the condition for SPPI are considered, including: (i) contingent and leverage features, (ii) non-recourse arrangements, (iii) features that could modify the time value of money, and (iv) Social, Environmental and Sustainability-linked features. Terms with de-minimis impact do not preclude cash flows from representing SPPI. The accounting policy for each type of financial asset or liability is included within the relevant note for the item. The Barclays Bank Group’s policies for determining the fair values of the assets and liabilities are set out in Note 16. Derecognition The Barclays Bank Group derecognises a financial asset, or a portion of a financial asset, from its balance sheet where (i) the contractual rights to cash flows from the asset have expired, or (ii) the contractual rights to the cash flows from the asset have been transferred (usually by sale) and with them either (a) substantially all the risks and rewards of the asset have been transferred, or (b) where neither substantially all the risks and rewards have been transferred or retained, where control over the asset has been lost. Financial liabilities are de-recognised when the liability has been settled, has expired or has been extinguished. An exchange of an existing financial liability for a new liability with the same lender on substantially different terms – generally a difference of 10% or more in the present value of the cash flows or a substantive qualitative amendment – is accounted for as an extinguishment of the original financial liability and the recognition of a new financial liability. It may not be obvious whether substantially all of the risks and rewards of a transferred asset, or portion of an asset, have been transferred. It is often necessary to perform a quantitative analysis that compares the Barclays Bank Group's exposure to variability in asset cash flows before the transfer with its retained exposure after the transfer. A cash flow analysis of this nature may require judgement. In particular, it is necessary to estimate the asset’s expected future cash flows as well as potential variability around this expectation. The method of estimating expected future cash flows depends on the nature of the asset, with market and market-implied data used to the greatest extent possible. The potential variability around this expectation is typically determined by stressing underlying parameters to create reasonable alternative upside and downside scenarios. Probabilities are then assigned to each scenario. Stressed parameters may include default rates, loss severity, or prepayment rates.
Accounting for reverse repurchase and repurchase agreements including other similar lending and borrowing	Accounting for reverse repurchase and repurchase agreements including other similar lending and borrowing Reverse repurchase agreements (and stock borrowing or similar transactions) are a form of secured lending whereby the Barclays Bank Group provides a loan or cash collateral in exchange for the transfer of collateral, generally in the form of marketable securities subject to an agreement to transfer the securities back at a fixed price in the future. Repurchase agreements are where the Barclays Bank Group obtains such loans or cash collateral, in exchange for the transfer of collateral. The Barclays Bank Group purchases (a reverse repurchase agreement) or borrows securities subject to a commitment to resell or return them. The securities are not included in the balance sheet as the Barclays Bank Group does not acquire the risks and rewards of ownership. Consideration paid (or cash collateral provided) is accounted for as a loan asset at amortised cost, unless it is designated or mandatorily at fair value through profit and loss. The Barclays Bank Group may also sell (a repurchase agreement) or lend securities subject to a commitment to repurchase or redeem them. The securities are retained on the balance sheet as the Barclays Bank Group retains substantially all the risks and rewards of ownership. Consideration received (or cash collateral provided) is accounted for as a financial liability at amortised cost, unless it is designated at fair value through profit and loss.
Issued debt and equity instruments	Issued debt and equity instruments Issued financial instruments or their components are classified as liabilities if the contractual arrangement results in the Barclays Bank Group having an obligation to either deliver cash or another financial asset, or a variable number of equity shares, to the holder of the instrument. If this is not the case, the instrument is generally an equity instrument and the proceeds included in equity, net of transaction costs. Dividends and other returns to equity holders are recognised when paid or declared by the members at the Annual General Meeting and treated as a deduction from equity. Where issued financial instruments contain both liability and equity components, these are accounted for separately. The fair value of the debt is estimated first and the balance of the proceeds is included within equity.
Cash flow statement	Cash flow statement Cash comprises cash on hand and balances at central banks. Cash equivalents comprise loans and advances to banks, cash collateral balances with central banks related to payment schemes and treasury and other eligible bills, all with original maturities of three months or less. Investments in debt securities at amortised cost are deemed to be investing activities for the purposes of the cash flow statement, except those instruments considered to be cash equivalents .
New and amended standards and interpretations	New and amended standards and interpretations The accounting policies adopted have been consistently applied, with the exception of the following: Classification of Liabilities as Current or Non-current (Amendments to IAS 1) In January 2020 the IASB issued amendments to IAS 1 to clarify the presentation of liabilities in the balance sheet, with an effective date that was subsequently deferred to 1 January 2024. The amendments clarify that a liability should be classified as non-current only if the entity has the right to defer settlement of the liability for at least 12 months after the reporting period, and that (i) the right to defer settlement must exist at the end of the reporting period and (ii) management’s intentions or expectations about whether it will exercise its right to defer settlement does not affect the classification. Further clarifications include how lending conditions affect classification and classification of liabilities the entity will or may settle by issuing its own equity instruments. In October 2022, the IASB also issued further amendments to IAS 1 to improve the information an entity provides when its right to defer settlement of a liability for at least 12 months is subject to compliance with covenants, and to respond to stakeholders’ concerns about the classification of such a liability as current or non-current. The impact to the Barclays Bank Group from these amendments is not considered to be material . Future accounting developments The following accounting standards have been issued by the IASB but are not yet effective: Amendment to IFRS 9 and IFRS 7 - Classification and Measurement of Financial Instruments In May 2024, the IASB issued targeted amendments to IFRS 9 to address feedback received from stakeholders following a post- implementation review. The amendments include: • additional guidance to clarify when certain financial assets may be compliant with SPPI requirements, including instruments with contingent features (e.g. ESG-linked financing), as well as contractually-linked instruments and non-recourse financing. • clarifying the derecognition requirements for financial assets and financial liabilities, including establishing a new accounting policy choice for derecognition of a financial liability when a payment is initiated by the reporting entity using an electronic payment system provided specified criteria is met. The amendments are effective from 1 January 2026, but are not yet endorsed for use in the UK. The Barclays Bank Group is currently assessing the impact of these amendments. IFRS 18 Presentation and Disclosure in Financial Statements In August 2024, the IASB issued a new IFRS Accounting Standard to replace IAS 1 Presentation of Financial Statements. The new standard creates detailed requirements for the classification and aggregation of income and expenses in the income statement, and disclosure requirements for management-defined performance measures. The new standard is effective from 1 January 2027, but has not yet been endorsed for use in the UK. The Barclays Bank Group is currently assessing the impact of these amendments. Amendments to IAS 21 - Lack of Exchangeability In August 2023, the IASB issued amendments to IAS 21 to define when a currency is exchangeable into another currency and, when it is not, to determine the exchange rate to use. The amendments are effective from 1 January 2025, however the impact to the Barclays Bank Group is not expected to be material . 6.
Critical accounting estimates and judgements	Critical accounting estimates and judgements The preparation of financial statements in accordance with IFRS requires the use of estimates. It also requires management to exercise judgement in applying the accounting policies. The key areas involving a higher degree of judgement or complexity or areas where assumptions are significant to the consolidated and individual financial statements are highlighted under the relevant note. Judgements Estimates Further information Credit impairment charges Identification and application of management adjustments in response to circumstances outside the scope of the model. Estimates include modelling assumptions such as estimating forward-looking modelled parameters (PD, EAD & LGD), and a range of unbiased future economic scenarios and scenario weightings. on page 173 Tax Recognition of deferred tax assets and determination of provisions for uncertain tax positions. Measurement of deferred tax balances and the level of provisioning for uncertain tax positions include forward- looking assumptions and estimates. on page 177 Fair value of financial instruments Classification of financial instruments with significant unobservable inputs as Level 3. Valuation of Level 3 assets and liabilities are typically determined by referencing observable inputs, historical data, or employing other analytical techniques. on page 193 Pensions and post-retirement benefit obligations - Valuation of defined benefit scheme obligations includes assumptions on post-retirement mortality, discount rates and inflation. on page 226 Provisions including conduct and legal, competition and regulatory matters Determination as to whether a present obligation exists. Estimation uncertainty in the probability, timing, nature and quantum of outflows. on page 212 7.
Accounting for interest income and expenses	Accounting for interest income and expenses Interest income on loans and advances at amortised cost, financial assets at fair value through other comprehensive income, interest expense on financial liabilities held at amortised cost are calculated using the effective interest method which allocates interest, and direct and incremental fees and costs, over the expected lives of the assets and liabilities. The effective interest method requires the Barclays Bank Group to estimate future cash flows, in some cases based on its experience of customers’ behaviour, considering all contractual terms of the financial instrument, as well as the expected lives of the assets and liabilities. The Barclays Bank Group incurs certain costs to originate credit card balances with the most significant being co-brand partner fees. To the extent these costs are attributed to customers that continuously carry an outstanding balance (revolvers) and incremental to the origination of credit card balances, they are capitalised and subsequently included within the calculation of the effective interest rate. They are amortised to interest income over the period of expected repayment of the originated balance. Costs attributed to customers that settle their outstanding balances each period (transactors) are deferred on the balance sheet as a cost of obtaining a contract and amortised to fee and commission expense over the life of the customer relationship (refer to Note 4). There are no other individual estimates involved in the calculation of effective interest rates that are material to the results or financial position.
Accounting for net fee and commission income	Accounting for net fee and commission income The Barclays Bank Group recognises fee and commission income charged for services provided by the Barclays Bank Group as and when performance obligations are satisfied, for example, on completion of the underlying transaction. Incremental costs are reported within fee and commission expense if they are directly attributable to generating identifiable fee and commission income. Where the contractual arrangements also result in the Barclays Bank Group recognising financial instruments in scope of IFRS 9, such financial instruments are initially recognised at fair value in accordance with IFRS 9 before applying the provisions of IFRS 15.
Accounting for net trading income	Accounting for net trading income Trading positions are held at fair value, and the resulting gains and losses are included in net trading income, together with interest and dividends arising from long and short positions and funding costs relating to trading activities. Incremental costs are reported within net trading income if they are directly attributable to generating identifiable trading income. Income arises from both the sale and purchase of trading positions, margins which are achieved through market making and customer business and from changes in fair value caused by movements in interest and exchange rates, equity prices and other market variables. Gains or losses on non-trading financial instruments designated or mandatorily at fair value with changes in fair value recognised in the income statement are included in net trading income.
Accounting for net investment income/(expense)	Accounting for net investment income/(expense) Dividends are recognised when the right to receive the dividend has been established. Incremental costs are reported within net investment income if they are directly attributable to generating identifiable investment income. Other accounting policies relating to net investment income are set out in Note 12 and Note 14.
Accounting for the impairment of financial assets	Accounting for the impairment of financial assets Impairment In accordance with IFRS 9 , the Barclays Bank Group is required to recognise expected credit losses (ECLs) based on unbiased forward- looking information for all financial assets at amortised cost, lease receivables, debt financial assets at fair value through other comprehensive income, loan commitments and financial guarantee contracts. Intercompany exposures in the individual financial statements, including loan commitments and financial guarantee contracts, are also in scope of IFRS 9 for ECL purposes. At the reporting date, an allowance (or provision for loan commitments and financial guarantees) is required for the 12 month (Stage 1 ) ECLs. If the credit risk has significantly increased since initial recognition (Stage 2), or if the financial instrument is credit impaired (Stage 3), an allowance (or provision) should be recognised for the lifetime ECLs. The measurement of ECL is calculated using three main components: (i) probability of default (PD) (ii) loss given default (LGD) and (iii) the exposure at default (EAD). The 12 month and lifetime ECLs are calculated by multiplying the respective PD, LGD and the EAD. The 12 month and lifetime PDs represent the PD occurring over the next 12 months and the remaining maturity of the instrument respectively. The EAD represents the expected balance at default, taking into account the repayment of principal and interest from the balance sheet date to the default event together with any expected drawdowns of committed facilities. The LGD represents expected losses on the EAD given the event of default, taking into account, among other attributes, the mitigating effect of collateral value at the time it is expected to be realised and the time value of money. Expected credit loss measurement is based on the ability of borrowers to make payments as they fall due. The Barclays Bank Group also considers sector specific risks and whether additional adjustments are required in the measurement of ECL. Credit risk may be impacted by climate considerations for certain sectors, such as oil and gas. Determining a significant increase in credit risk since initial recognition: The Barclays Bank Group assesses when a significant increase in credit risk has occurred based on quantitative and qualitative assessments. The credit risk of an exposure is considered to have significantly increased when: i) Quantitative test The annualised lifetime PD has increased by more than an agreed threshold relative to the equivalent at origination. PD deterioration thresholds are defined as percentage increases, and are set at an origination score band and segment level to ensure the test appropriately captures significant increases in credit risk at all risk levels. Generally, thresholds are inversely correlated to the origination PD, i.e. as the origination PD increases, the threshold value reduces. The assessment of the point at which a PD increase is deemed ‘significant’ is based upon analysis of the portfolio’s risk profile against a common set of principles and performance metrics (consistent across both retail and wholesale businesses), incorporating expert credit judgement where appropriate. Application of quantitative PD floors does not represent the use of the low credit risk exemption as exposures can separately move into stage 2 via the qualitative route described below. Wholesale assets apply a 100% increase in PD and 0.2% PD floor to determine a significant increase in credit risk. Retail assets apply bespoke relative increase and absolute PD thresholds based on product type and origination PD. Thresholds are subject to maximums defined by Barclays Bank Group policy and typically apply minimum relative thresholds of 50% - 100% and a maximum relative threshold of 400% For existing/historical exposures where origination point scores or data are no longer available or do not represent a comparable estimate of lifetime PD, a proxy origination score is defined, based upon: ▪ back-population of the approved lifetime PD score either to origination date or, where this is not feasible, as far back as possible (subject to a data start point no later than 1 January 2015); or ▪ use of available historical account performance data and other customer information, to derive a comparable ‘proxy’ estimation of origination PD. ii) Qualitative test This is relevant for accounts that meet the portfolio’s ‘high risk’ criteria and are subject to closer credit monitoring. High risk customers may not be in arrears but either through an event or an observed behaviour exhibit credit distress. The definition and assessment of high risk includes as wide a range of information as reasonably available, such as industry and Barclays Bank Group-wide customer level data, including but not limited to bureau scores and high consumer indebtedness index, wherever possible or relevant. Whilst the high risk populations applied for IFRS 9 impairment purposes are aligned with risk management processes, they are also regularly reviewed and validated to ensure that they capture any incremental segments where there is evidence of credit deterioration. iii) Backstop criteria This is relevant for accounts that are more than 30 calendar days past due. The 30 days past due criteria is a backstop rather than a primary driver of moving exposures into Stage 2 . The criteria for determining a significant increase in credit risk for assets with bullet repayments follows the same principle as all other assets, i.e. quantitative, qualitative and backstop tests are all applied. Exposures will move back to Stage 1 once they no longer meet the criteria for a significant increase in credit risk. This means that, at a minimum all payments must be up-to-date, the PD deterioration test is no longer met, the account is no longer classified as high risk, and the customer has evidenced an ability to maintain future payments. Exposures are only removed from Stage 3 and re-assigned to Stage 2 once the original default trigger event no longer applies. Exposures being removed from Stage 3 must no longer qualify as credit impaired, and: a) the obligor will also have demonstrated consistently good payment behaviour over a 12 -month period, by making all consecutive contractual payments due and, for forborne exposures, the relevant EBA defined probationary period has also been successfully completed; or b) (for non-forborne exposures) the performance conditions are defined and approved within an appropriately sanctioned restructure plan, including 12 months’ payment history have been met. Management overlays and other exceptions to model outputs are applied only if consistent with the objective of identifying significant increases in credit risk. Forward-looking information The measurement of ECL involves complexity and judgement, including estimation of PD, LGD, a range of unbiased future economic scenarios, estimation of expected lives (where contractual life is not appropriate), and estimation of EAD and assessing significant increases in credit risk. Credit losses are the expected cash shortfalls from what is contractually due over the expected life of the financial instrument, discounted at the original effective interest rate (EIR). ECLs are the unbiased probability-weighted credit losses determined by evaluating a range of possible outcomes and considering future economic conditions. Refer to the Measurement uncertainty and sensitivity analysis section on page 93 for further details. Definition of default, credit impaired assets, write-offs, and interest income recognition The definition of default for the purpose of determining ECLs, and for internal credit risk management purposes, has been aligned to the Regulatory Capital CRR Article 178 definition of default, to maintain a consistent approach with IFRS 9 and associated regulatory guidance. The Regulatory Capital CRR Article 178 definition of default considers indicators that the debtor is unlikely to pay, includes exposures in forbearance and is no later than when the exposure is more than 90 days past due. When exposures are identified as credit impaired at the time when they are purchased or originated, interest income is calculated on the carrying value net of the impairment allowance. An asset is considered credit impaired when one or more events occur that have a detrimental impact on the estimated future cash flows of the financial asset. This comprises assets defined as defaulted and other individually assessed exposures where imminent default or actual loss is identified. Uncollectible loans are written off against the related allowance for loan impairment on completion of the Barclays Bank Group’s internal processes and when all reasonably expected recoverable amounts have been collected. Subsequent recoveries of amounts previously written off are credited to the income statement. The timing and extent of write-offs may involve some element of subjective judgement. Nevertheless, a write-off will often be prompted by a specific event, such as the inception of insolvency proceedings or other formal recovery action, which makes it possible to establish that some or the entire advance is beyond realistic prospect of recovery. Accounting for purchased financial guarantee contracts The Barclays Bank Group may enter into a financial guarantee contract which requires the issuer of such contract to reimburse the Barclays Bank Group for a loss it incurs because a specified debtor fails to make payment when due in accordance with the terms of a debt instrument. For these separate financial guarantee contracts, the Barclays Bank Group recognises a reimbursement asset aligned with the recognition of the underlying ECLs, if it is considered virtually certain that a reimbursement would be received if the specified debtor fails to make payment when due in accordance with the terms of the debt instrument. Loan modifications and renegotiations that are not credit-impaired When modification of a loan agreement occurs as a result of commercial restructuring activity rather than due to the credit risk of the borrower, an assessment must be performed to determine whether the terms of the new agreement are substantially different from the terms of the existing agreement. This assessment considers both the change in cash flows arising from the modified terms as well as the change in overall instrument risk profile. In respect of payment holidays granted to borrowers which are not due to forbearance, if the revised cash flows on a present value basis (based on the original EIR) are not substantially different from the original cash flows, the loan is not considered to be substantially modified. Where terms are substantially different, the existing loan will be derecognised and a new loan will be recognised at fair value, with any difference in valuation recognised immediately within the income statement, subject to observability criteria. Where terms are not substantially different, the loan carrying value will be adjusted to reflect the present value of modified cash flows discounted at the original EIR, with any resulting gain or loss recognised immediately within the income statement as a modification gain or loss. Expected life Lifetime ECLs must be measured over the expected life. This is restricted to the maximum contractual life and takes into account expected prepayment, extension, call and similar options. The exceptions are certain revolver financial instruments, such as credit cards and bank overdrafts, that include both a drawn and an undrawn component where the entity’s contractual ability to demand repayment and cancel the undrawn commitment does not limit the entity’s exposure to credit losses to the contractual notice period. For revolving facilities, expected life is analytically derived to reflect the behavioural life of the asset, i.e. the full period over which the business expects to be exposed to credit risk. Behavioural life is typically based upon historical analysis of the average time to default, closure or withdrawal of facility. Where data is insufficient or analysis inconclusive, an additional ‘maturity factor’ may be incorporated to reflect the full estimated life of the exposures, based upon experienced judgement and/or peer analysis. Potential future modifications of contracts are not taken into account when determining the expected life or EAD until they occur. Discounting ECLs are discounted at the EIR at initial recognition or an approximation thereof and consistent with income recognition. For loan commitments the EIR is the rate that is expected to apply when the loan is drawn down and a financial asset is recognised. Issued financial guarantee contracts are discounted at the risk-free rate. Lease receivables are discounted at the rate implicit in the lease. For variable/ floating rate financial assets, the spot rate at the reporting date is used and projections of changes in the variable rate over the expected life are not made to estimate future interest cash flows or for discounting. Modelling techniques Currently, Internal Ratings-Based models are leveraged to calculate the point-in-time PD and LGD, which serve as key inputs to the IFRS 9 models. Thereafter, these inputs are extrapolated by the IFRS 9 models to create macroeconomic sensitive forecast of PDs, LGDs and in turn ECL. Forbearance A financial asset is subject to forbearance when it is modified due to the credit distress of the borrower. A modification made to the terms of an asset due to forbearance will typically be assessed as a non-substantial modification that does not result in derecognition of the original loan, except in circumstances where debt is exchanged for equity. Both performing and non-performing forbearance assets are classified as Stage 3 except where it is established that the concession granted has not resulted in diminished financial obligation and that no other regulatory definitions of default criteria have been triggered, in which case the asset is classified as Stage 2 . The minimum probationary period for non-performing forbearance is 12 months and for performing forbearance, 24 months . Hence, a minimum of 36 months is required for non-performing forbearance to move out of a forborne state. No financial instrument in forbearance can transfer back to Stage 1 until all of the Stage 2 thresholds are no longer met and can only move out of Stage 3 when no longer credit impaired. Critical accounting estimates and judgements IFRS 9 impairment involves several important areas of judgement, including estimating forward looking modelled parameters (PD, LGD and EAD), developing a range of unbiased future economic scenarios, estimating expected lives and assessing significant increases in credit risk, based on the Barclays Bank Group’s experience of managing credit risk. The determination of expected life is most material for Barclays Bank Group's credit card portfolios which is obtained via behavioural life analysis to materially capture the risk of these facilities. Within the retail and small businesses portfolios, which comprise large numbers of small homogenous assets with similar risk characteristics where credit scoring techniques are generally used, the impairment allowance is calculated using forward looking modelled parameters which are typically run at account level. There are many models in use, each tailored to a product, line of business or customer category. Judgement and knowledge is needed in selecting the statistical methods to use when the models are developed or revised. Management adjustments to impairment models, which contain an element of subjectivity, are applied in order to factor in certain conditions or changes in policy that are not fully incorporated into the impairment models, or to reflect additional facts and circumstances at the period end. Management adjustments are reviewed and incorporated into future model development where appropriate . For individually significant assets in Stage 3 , impairment allowances are calculated on an individual basis and all relevant considerations that have a bearing on the expected future cash flows across a range of economic scenarios are taken into account. These considerations can be particularly subjective and can include the business prospects for the customer, the realisable value of collateral, the Barclays Bank Group’s position relative to other claimants, the reliability of customer information and the likely cost and duration of the work-out process. The level of the impairment allowance is the difference between the value of the discounted expected future cash flows (discounted at the loan’s original effective interest rate), and its carrying amount. Furthermore, judgements change with time as new information becomes available or as work-out strategies evolve, resulting in frequent revisions to the impairment allowance as individual decisions are taken. Changes in these estimates would result in a change in the allowances and have a direct impact on the impairment charge. Temporary adjustments to calculated IFRS 9 impairment allowances may be applied in limited circumstances to account for situations where known or expected risk factors or information have not been considered in the ECL assessment or modelling process. For further information please see pages 91 to 92 in credit risk performance. Information about the potential impact of the physical and transition risks of climate change on borrowers is considered, taking into account reasonable and supportable information to make accounting judgements and estimates. Climate change is inherently of a long- term nature, with significant levels of uncertainty, and consequently requires judgement in determining the possible impact in the next financial year, if any.
Accounting for purchased financial guarantee contracts	The Barclays Bank Group may enter into a financial guarantee contract which requires the issuer of such contract to reimburse the Barclays Bank Group for a loss it incurs because a specified debtor fails to make payment when due in accordance with the terms of a debt instrument. For these separate financial guarantee contracts, the Barclays Bank Group recognises a reimbursement asset aligned with the recognition of the underlying ECLs, if it is considered virtually certain that a reimbursement would be received if the specified debtor fails to make payment when due in accordance with the terms of the debt instrument.
Accounting for income taxes	Accounting for income taxes The Barclays Bank Group applies IAS 12 Income Taxes in accounting for taxes on income. Income tax payable on taxable profits (current tax) is recognised as an expense in the periods in which the profits arise. Withholding taxes are also treated as income taxes. Income tax recoverable on tax allowable losses is recognised as a current tax asset only to the extent that it is regarded as recoverable by offsetting against taxable profits arising in the current or prior periods. Current tax is measured using tax rates and tax laws that have been enacted or substantively enacted at the balance sheet date. Deferred tax assets are recognised to the extent that it is probable that taxable profit will be available against which the deductible temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilised. Deferred tax liabilities are recognised for all taxable temporary differences except for the initial recognition of goodwill. Deferred tax is not recognised where the temporary difference arises from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss. Deferred tax is determined using tax rates and legislation enacted or substantively enacted by the balance sheet date which are expected to apply when the deferred tax asset is realised or the deferred tax liability is settled. Deferred tax assets and liabilities are only offset when there is both a legal right to set-off and an intention to settle on a net basis. The Barclays Bank Group has adopted the International Tax Reform - Pillar Two Model Rules amendments to IAS 12, which were issued on 23 May 2023 and approved by the UK Endorsement Board on 19 July 2023, and has applied the exception set out in paragraph 4A in respect of recognising and disclosing information about deferred tax assets and liabilities related to Pillar Two income taxes. The Barclays Bank Group considers an uncertain tax position to exist when it considers that ultimately, in the future, the amount of profit subject to tax may be greater than the amount initially reflected in the Barclays Bank Group’s tax returns. The Barclays Bank Group accounts for provisions in respect of uncertain tax positions in two different ways. A current tax provision is recognised when it is considered probable that the outcome of a review by a tax authority of an uncertain tax position will alter the amount of cash tax due to, or from, a tax authority in the future. From recognition, the current tax provision is then measured at the amount the Barclays Bank Group ultimately expects to pay the tax authority to resolve the position. The accrual of interest and penalty amounts in respect of uncertain income tax positions is recognised as an expense within profit before tax. Deferred tax provisions are adjustments made to the carrying value of deferred tax assets in respect of uncertain tax positions. A deferred tax provision is recognised when it is considered probable that the outcome of a review by a tax authority of an uncertain tax position will result in a reduction in the carrying value of the deferred tax asset. From recognition of a provision, measurement of the underlying deferred tax asset is adjusted to take into account the expected impact of resolving the uncertain tax position on the loss or temporary difference giving rise to the deferred tax asset. The approach taken to measurement takes account of whether the uncertain tax position is a discrete position that will be reviewed by the tax authority in isolation from any other position, or one of a number of issues which are expected to be reviewed together concurrently and resolved simultaneously with a tax authority. The Barclays Bank Group’s measurement of provisions is based upon its best estimate of the additional profit that will become subject to tax. For a discrete position, consideration is given only to the merits of that position. Where a number of issues are expected to be reviewed and resolved together, the Barclays Bank Group will take into account not only the merits of its position in respect of each particular issue but also the overall level of provision relative to the aggregate of the uncertain tax positions across all the issues that are expected to be resolved at the same time. In addition, in assessing provision levels, it is assumed that tax authorities will review uncertain tax positions and that all facts will be fully and transparently disclosed. Critical accounting estimates and judgements There are two key areas of judgement that impact the reported tax position. Firstly, the level of provisioning for uncertain tax positions; and secondly, the recognition and measurement of deferred tax assets. The Barclays Bank Group does not consider there to be a significant risk of a material adjustment to the carrying amount of current and deferred tax balances, including provisions for uncertain tax positions in the next financial year. The provisions for uncertain tax positions cover a diverse range of issues and reflect advice from external counsel where relevant. It should be noted that only a proportion of the total uncertain tax positions will be under audit at any point in time, and could therefore be subject to challenge by a tax authority over the next year. Deferred tax assets have been recognised based on business profit forecasts which included consideration for the current view of climate impacts. Details on the recognition of deferred tax assets are provided in this note.
Accounting for trading portfolio assets and liabilities	Accounting for trading portfolio assets and liabilities All assets and liabilities held for trading purposes are held at fair value with gains and losses in the changes in fair value taken to the income statement in net trading income (Note 5).
Accounting for financial instruments at fair value	Accounting for financial assets designated at fair value Financial assets, other than those held for trading, are classified in this category if they are so irrevocably designated at inception and the use of the designation removes or significantly reduces an accounting mismatch. Subsequent changes in fair value for these instruments are recognised in the income statement in net investment income, except if reporting it in trading income reduces an accounting mismatch. The details on how the fair value amounts are derived for financial assets at fair value are described in Note 16. Accounting for financial assets mandatorily at fair value Financial assets that are held for trading are recognised at fair value through profit or loss. In addition, financial assets are held at fair value through profit or loss if they do not contain contractual terms that give rise on specified dates to cash flows that are Solely Payments of Principal and Interest (SPPI), or if the financial asset is not held in a business model that is either (i) a business model to collect the contractual cash flows or (ii) a business model that is achieved by both collecting contractual cash flows and selling.
Accounting for derivatives	Accounting for derivatives Derivative instruments are contracts whose value is derived from one or more underlying financial instruments or indices defined in the contract. They include swaps, forward-rate agreements, futures, options and combinations of these instruments and primarily affect the Barclays Bank Group’s net interest income, net trading income and derivative assets and liabilities. Notional amounts of the contracts are not recorded on the balance sheet. Derivatives are used to hedge interest rate, credit risk, inflation risk, exchange rate, commodity, equity exposures and exposures to certain indices such as house price indices and retail price indices related to non-trading positions. All derivative instruments are held at fair value through profit or loss, except for derivatives that are in a designated cash flow or net investment hedge accounting relationship. Derivatives are classified as assets when their fair value is positive or as liabilities when their fair value is negative.
Accounting for hedging	Hedge accounting The Barclays Bank Group applies the requirements of IAS 39 Financial Instruments: Recognition and Measurement for hedge accounting purposes. The Barclays Bank Group applies hedge accounting to represent the economic effects of its interest rate, currency and contractually linked inflation risk management strategies. Where derivatives are held for risk management purposes, and when transactions meet the required criteria for documentation and hedge effectiveness, the Barclays Bank Group applies fair value hedge accounting, cash flow hedge accounting, or hedging of a net investment in a foreign operation, as appropriate to the risks being hedged. Fair value hedge accounting Changes in fair value of derivatives that qualify and are designated as fair value hedges are recorded in the income statement, together with changes in the fair value of the hedged asset or liability that are attributable to the hedged risk. The fair value changes adjust the carrying value of the hedged asset or liability held at amortised cost. If hedge relationships no longer meet the criteria for hedge accounting, hedge accounting is discontinued. For fair value hedges of interest rate risk, the fair value adjustment to the hedged item is amortised to the income statement over the period to maturity of the previously designated hedge relationship using the effective interest method. If the hedged item is sold or repaid, the unamortised fair value adjustment is recognised immediately in the income statement. For items classified as fair value through other comprehensive income, the hedge accounting adjustment is included in other comprehensive income. Cash flow hedge accounting For qualifying cash flow hedges, the fair value gain or loss associated with the effective portion of the cash flow hedge is recognised initially in other comprehensive income, and then recycled to the income statement in the periods when the hedged item will affect profit or loss. Any ineffective portion of the gain or loss on the hedging instrument is recognised in the income statement immediately. 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 when the hedged item is ultimately recognised in the income statement. When a forecast transaction is no longer expected to occur, the cumulative gain or loss that was recognised in equity is immediately transferred to the income statement. Hedges of net investments The Barclays Bank Group’s net investments in foreign operations, including monetary items accounted for as part of the net investment, are hedged for foreign currency risks using both derivatives and foreign currency borrowings. Hedges of net investments are accounted for similarly to cash flow hedges; the effective portion of the gain or loss on the hedging instrument is being recognised directly in other comprehensive income and the ineffective portion being recognised immediately in the income statement. The cumulative gain or loss recognised in other comprehensive income is recognised in the income statement on the disposal or partial disposal of the foreign operation, or other reductions in the Barclays Bank Group’s investment in the operation.
Accounting for financial assets at fair value through other comprehensive income	Accounting for financial assets at fair value through other comprehensive income (FVOCI) Financial assets that are debt instruments held in a business model that is achieved by both collecting contractual cash flows and selling and that contain contractual terms that give rise on specified dates to cash flows that are SPPI are measured at FVOCI. They are subsequently re-measured at fair value and changes therein (except for those relating to impairment, interest income and foreign currency exchange gains and losses) are recognised in other comprehensive income until the assets are sold. Interest (calculated using the effective interest method) is recognised in the income statement in net interest income (Note 3). Upon disposal, the cumulative gain or loss recognised in other comprehensive income is included in net investment income (Note 6). In determining whether the business model is achieved by both collecting contractual cash flows and selling financial assets, it is determined that both collecting contractual cash flows and selling financial assets are integral to achieving the objective of the business model. The Barclays Bank Group will consider past sales and expectations about future sales to establish if the business model is achieved. For equity securities that are not held for trading, the Barclays Bank Group may make an irrevocable election on initial recognition to present subsequent changes in the fair value of the instrument in other comprehensive income (except for dividend income which is recognised in profit or loss).
Accounting for financial liabilities at fair value through profit and loss	Accounting for liabilities designated at fair value through profit and loss In accordance with IFRS 9, financial liabilities may be designated at fair value, with gains and losses taken to the income statement within net trading income (Note 5) and net investment income (Note 6). Movements in own credit are reported through other comprehensive income, unless the effects of changes in the liability's credit risk would create or enlarge an accounting mismatch in profit and loss. In these scenarios, all gains and losses on that liability (including the effects of changes in the credit risk of the liability) are presented in profit and loss. On derecognition of the financial liability no amounts relating to own credit risk are recycled to the income statement. The Barclays Bank Group has the ability to make the fair value designation when holding the instruments at fair value reduces an accounting mismatch (caused by an offsetting liability or asset being held at fair value), or is managed by the Barclays Bank Group on the basis of its fair value, or includes terms that have substantive derivative characteristics (Note 13). The details on how the fair value amounts are arrived at for financial liabilities designated at fair value are described in Note 16.
Accounting for financial assets and liabilities - fair values	Accounting for financial assets and liabilities – fair value Financial instruments that are held for trading are recognised at fair value through profit or loss. In addition, financial assets are held at fair value through profit or loss if they do not contain contractual terms that give rise on specified dates to cash flows that are SPPI, or if the financial asset is not held in a business model that is either (i) a business model to collect the contractual cash flows or (ii) a business model that is achieved by both collecting contractual cash flows and selling. Subsequent changes in fair value for these instruments are recognised in the income statement in net investment income, except if reporting it in trading income reduces an accounting mismatch. Wherever possible, fair value is determined by reference to a quoted market price for that instrument. For many of the Barclays Bank Group’s financial assets and liabilities, especially derivatives, quoted prices are not available and valuation models are used to estimate fair value. The models calculate the expected cash flows under the terms of each specific contract and then discount these values back to a present value. These models use as their basis independently sourced market inputs including, for example, interest rate yield curves, equities and commodities prices, option volatilities and currency rates. For financial liabilities measured at fair value, the carrying amount reflects the effect on fair value of changes in own credit spreads derived from observable market data such as in primary issuance and redemption activity for structured notes. On initial recognition, it is presumed that the transaction price is the fair value unless there is observable information available in an active market to the contrary. For valuations that have made use of unobservable inputs, the difference between the model valuation and the initial transaction price (Day One profit) is recognised in profit or loss either: on a straight-line basis over the term of the transaction; or over the period until all inputs will become observable where appropriate; or released in full when previously unobservable inputs become observable. Various factors influence the availability of observable inputs, and these may vary from product to product and change over time. Factors include the depth of activity in the relevant market, the type of product, whether the product is new and not widely traded in the marketplace, the maturity of market modelling and the nature of the transaction (bespoke or generic). To the extent that valuation is based on models or inputs that are not observable in the market, the determination of fair value can be more subjective, dependent on the significance of the unobservable input to the overall valuation. Unobservable inputs are determined based on the best information available, for example by reference to similar assets, similar maturities, or other analytical techniques. The sensitivity of valuations used in the financial statements to possible changes in significant unobservable inputs is shown on page 201 . Critical accounting estimates and judgements The valuation of financial instruments often involves a significant degree of judgement and complexity, in particular where valuation models make use of unobservable inputs (‘Level 3’ assets and liabilities). This note provides information on these instruments, including the related unrealised gains and losses recognised in the period, a description of significant valuation techniques and unobservable inputs, and a sensitivity analysis. Climate related risks are assumed to be included in the fair values of assets and liabilities traded in active markets. Within less active markets, for counterparties and instruments identified as being more susceptible to climate change risk, an impact assessment was performed by increasing their probability of default. The change in the valuation of the assets and liabilities from this assessment was not sufficiently material to necessitate any amendment to the reported 2024 year-end valuations.
Accounting for offsetting financial assets and financial liabilities	The Barclays Bank Group reports financial assets and financial liabilities on a net basis on the balance sheet only if there is a legally enforceable right to set-off the recognised amounts and there is intention to settle on a net basis, or to realise the asset and settle the liability simultaneously. The following table shows the impact of netting arrangements on: ▪ All financial assets and liabilities that are reported net on the balance sheet. ▪ All derivative financial instruments and reverse repurchase and repurchase agreements and other similar secured lending and borrowing agreements that are subject to enforceable master netting arrangements or similar agreements, but do not qualify for balance sheet netting. The ‘Net amounts’ presented in the table below are not intended to represent the Barclays Bank Group’s actual exposure to credit risk, as a variety of credit mitigation strategies are employed in addition to netting and collateral arrangements.
Accounting for property, plant and equipment	Accounting for property, plant and equipment Property, plant and equipment is stated at cost, which includes direct and incremental acquisition costs less accumulated depreciation and provisions for impairment, if required. Subsequent costs are capitalised if these result in enhancement of the asset. Depreciation is provided on the depreciable amount of items of property, plant and equipment on a straight-line basis over their estimated useful economic lives. Depreciation rates, methods and the residual values underlying the calculation of depreciation of items of property, plant and equipment are kept under review to take account of any change in circumstances including consideration on future Climate and Sustainability investments. The Barclays Bank Group and Barclays Bank PLC use the following annual rates in calculating depreciation: Annual rates in calculating depreciation Depreciation rate Freehold land Not depreciated Freehold buildings 2% - 3.3% Leasehold property Over the remaining life of the lease Costs of adaptation of freehold and leasehold property 6% - 10% Equipment installed in freehold and leasehold property 6% - 10% Computers and similar equipment 17% - 33% Fixtures and fittings and other equipment 9% - 20% Costs of adaptation and installed equipment are depreciated over the shorter of the life of the lease or the depreciation rates noted in the table above. Investment property The Barclays Bank Group and Barclays Bank PLC initially recognises investment property at cost, and subsequently at fair value at each balance sheet date, reflecting market conditions at the reporting date. Gains and losses on remeasurement are included in the income statement.
Accounting for leases	Accounting for leases When the Barclays Bank Group or Barclays Bank PLC are the lessee, they are required to recognise both: ▪ a lease liability, measured at the present value of remaining cash flows on the lease ▪ a r ight of use (ROU) asset, measured at the amount of the initial measurement of the lease liability, plus any lease payments made prior to commencement date, initial direct costs, and estimated costs of restoring the underlying asset to the condition required by the lease, less any lease incentives received. Subsequently the lease liability will increase for the accrual of interest, resulting in a constant rate of return throughout the life of the lease, and reduce when payments are made. The right of use asset will amortise to the income statement over the life of the lease. On the balance sheet, the ROU assets are included within property, plant and equipment and the lease liabilities are included within other liabilities . The Barclays Bank Group and Barclays Bank PLC apply the recognition exemption in IFRS 16 for leases with a term not exceeding 12 months. For these leases the lease payments are recognised as an expense on a straight line basis over the lease term unless another systematic basis is more appropriate. When the Barclays Bank Group or Barclays Bank PLC are the lessor, the lease must be classified as either a finance lease or an operating lease. A finance lease is a lease which confers substantially all the risks and rewards of the leased assets on the lessee. An operating lease is a lease where substantially all of the risks and rewards of the leased asset remain with the lessor.
Accounting for goodwill and intangible assets	Accounting for goodwill and intangible assets Goodwill Goodwill arising on the acquisition of subsidiaries represents the excess of the fair value of the purchase consideration over the fair value of the Barclays Bank Group’s share of the assets acquired and the liabilities and contingent liabilities assumed on the date of the acquisition. Goodwill is reviewed annually for impairment, or more frequently when there are indications that impairment may have occurred. The test involves comparing the carrying value of the cash generating unit (CGU) including goodwill with the present value of the pre-tax cash flows, discounted at a rate of interest that reflects the inherent risks, of the CGU to which the goodwill relates, or the CGUs fair value if this is higher. Intangible assets Intangible assets are initially recognised when they are separable or arise from contractual or other legal rights, the cost can be measured reliably and, in the case of intangible assets not acquired in a business combination, where it is probable that future economic benefits attributable to the assets will flow from their use. For internally generated intangible assets, only costs incurred during the development phase are capitalised. Expenditure in the research phase is expensed when it is incurred. Intangible assets are stated at cost (which is, in the case of assets acquired in a business combination, the acquisition date fair value) less accumulated amortisation and provisions for impairment, if any, and are amortised over their useful lives in a manner that reflects the pattern to which they contribute to future cash flows, generally using the amortisation periods set out below: Annual rates in calculating amortisation Amortisation period Goodwill Not amortised Internally generated software 1 12 months to 6 years Other software 12 months to 6 years Customer lists 12 months to 25 years Licences and other 12 months to 25 years Note 1 Exceptions to the above period relate to useful lives of certain core banking platforms that are assessed individually and, if appropriate, amortised over longer periods ranging from 10 years to 15 years . Intangible assets are reviewed for impairment when there are indications that impairment may have occurred. Intangible assets not yet available for use are reviewed annually for impairment.
Accounting for provisions	Accounting for provisions Provisions are recognised for present obligations arising as consequences of past events where it is more likely than not that a transfer of economic benefit will be necessary to settle the obligation, which can be reliably estimated . Critical accounting estimates and judgements The financial reporting of provisions involves a significant degree of judgement and is complex. Identifying whether a present obligation exists and estimating the probability, timing, nature and quantum of the outflows that may arise from past events requires judgements to be made based on the specific facts and circumstances relating to individual events and often requires specialist professional advice. When matters are at an early stage, accounting judgements and estimates can be difficult because of the high degree of uncertainty involved. Management continues to monitor matters as they develop to re-evaluate on an ongoing basis whether provisions should be recognised, however there can remain a wide range of possible outcomes and uncertainties, particularly in relation to legal, competition and regulatory matters, and as a result it is often not practicable to make meaningful estimates even when matters are at a more advanced stage. The amount that is recognised as a provision can also be very sensitive to the assumptions made in calculating it. This gives rise to a large range of potential outcomes which require judgement in determining an appropriate provision level. See Note 24 for more detail of legal, competition and regulatory matters.
Accounting for contingent liabilities	Accounting for contingent liabilities Contingent liabilities are possible obligations whose existence will be confirmed only by uncertain future events and present obligations where the transfer of economic resources is uncertain or cannot be reliably measured. Contingent liabilities are not recognised on the balance sheet but are disclosed unless the likelihood of an outflow of economic resources is remote.
Accounting for subordinated liabilities	Accounting for subordinated liabilities Subordinated liabilities are measured at amortised cost using the effective interest method under IFRS 9 , unless they are irrevocably designated at fair value through profit or loss at initial recognition because such designation eliminates or significantly reduces an accounting mismatch. Refer to Note 15 for details about accounting for liabilities designated at fair value through profit or loss.
Accounting for staff costs, pensions and post-retirement benefits	Accounting for staff costs Deferred cash and share awards are made to employees to incentivise performance over the period employees provide services. To receive an award, an individual must have provided service over the vesting period and been employed on the scheduled vesting date or be considered an eligible leaver. The expense for deferred cash and share awards is recognised over the period employees’ services contribute to the awards. The Barclays Bank Group considers it appropriate to recognise the expense over the vesting period including the financial year prior to the grant date . The accounting policies for share-based payments and pensions and other post-retirement benefits are included in Note 29 and Note 30 respectively. Accounting for pensions and post-retirement benefits The Barclays Bank Group operates a number of pension schemes and post-employment benefit schemes. Defined contribution schemes – the Barclays Bank Group recognises contributions due in respect of the accounting period in the income statement. Any contributions unpaid at the balance sheet date are included as a liability. Defined benefit schemes – the Barclays Bank Group recognises its obligations to members of each scheme at the period end, less the fair value of the scheme assets after applying the asset ceiling test. Each scheme’s obligations are calculated using the projected unit credit method. Scheme assets are stated at fair value as at the period end. Changes in pension scheme liabilities or assets (remeasurements) that do not arise from regular pension cost, net interest on net defined benefit liabilities or assets, past service costs, settlements or contributions to the scheme are recognised in other comprehensive income. Remeasurements comprise experience adjustments (differences between previous actuarial assumptions and what has actually occurred), the effects of changes in actuarial assumptions, return on scheme assets (excluding amounts included in the interest on the assets) and any changes in the effect of the asset ceiling restriction (excluding amounts included in the interest on the restriction). Post-employment benefit schemes – the cost of providing healthcare benefits to retired employees is accrued as a liability in the financial statements over the period that the employees provide services to the Barclays Bank Group, using a methodology similar to that for defined benefit pension schemes.
Accounting for share-based payments	Accounting for share-based payments Employee incentives include awards in the form of shares and share options, as well as offering employees the opportunity to purchase shares on favourable terms. The cost of the employee services received in respect of the shares or share options granted is recognised in the income statement over the period that employees provide services. The overall cost of the award is calculated using the number of shares and options expected to vest and the fair value of the shares or options at the date of grant. The number of shares and options expected to vest takes into account the likelihood that performance and service conditions included in the terms of the awards will be met. For other share-based payment schemes such as Sharesave and Sharepurchase, there are non-vesting conditions which must be met. Failure to meet the non-vesting condition is treated as a cancellation, resulting in an acceleration of recognition of the cost of the employee services. The fair value of shares is the market price ruling on the grant date, in some cases adjusted to reflect restrictions on transferability. The fair value of options granted is determined using the Black-Scholes model to estimate the numbers of shares likely to vest. The model takes into account the exercise price of the option, the current share price, the risk-free interest rate, the expected volatility of the share price over the life of the option and other relevant factors. Market conditions that must be met in order for the award to vest are also reflected in the fair value of the award, as are any other non-vesting conditions – such as continuing to make payments into a share-based savings scheme.
Accounting for investment in subsidiaries	Accounting for investment in subsidiaries In the individual financial statements of Barclays Bank PLC, investments in subsidiaries are stated at cost less impairment.
Accounting for securitisations	Accounting for securitisations The Barclays Bank Group uses securitisations as a source of finance and a means of risk transfer. Such transactions generally result in the transfer of contractual cash flows from portfolios of financial assets to holders of issued debt securities. Securitisations may, depending on the individual arrangement, result in continued recognition of the securitised assets and the recognition of the debt securities issued in the transaction; lead to partial continued recognition of the assets to the extent of the Barclays Bank Group’s continuing involvement in those assets or lead to derecognition of the assets and the separate recognition, as assets or liabilities, of any rights and obligations created or retained in the transfer. Full derecognition only occurs when the Barclays Bank Group transfers both its contractual right to receive cash flows from the financial assets, or retains the contractual rights to receive the cash flows, but assumes a contractual obligation to pay the cash flows to another party without material delay or reinvestment, and also transfers substantially all the risks and rewards of ownership, including credit risk, prepayment risk and interest rate risk.
Accounting for assets pledged, collateral received and assets transferred	Assets are pledged or transferred as collateral to secure liabilities under repurchase agreements, securitisations and stock lending agreements or as security deposits relating to derivatives. Assets transferred are non-cash assets transferred to a third party that do not qualify for derecognition from the Barclays Bank Group’s balance sheet, for example because the Barclays Bank Group retains substantially all the exposure to those assets under an agreement to repurchase them in the future for a fixed price. Where non-cash assets are pledged or transferred as collateral for cash received, the asset continues to be recognised in full, and a related liability is also recognised on the balance sheet. Where non-cash assets are pledged or transferred as collateral in an exchange for non-cash assets, the transferred asset continues to be recognised in full, and there is no associated liability as the non-cash collateral received is not recognised on the balance sheet. The Barclays Bank Group is unable to use, sell or pledge the transferred assets for the duration of the transaction and remains exposed to interest rate risk and credit risk on these pledged assets. Unless stated, the counterparty's recourse is not limited to the transferred assets. Collateralised transactions, such as securities lending and borrowing, repurchase and derivative transactions are conducted in accordance with standard terms which are customary in the market.
Accounting for non-current assets held for sale and associated liabilities	Accounting for non-current assets held for sale and associated liabilities The Barclays Bank Group applies IFRS 5 Non-current Assets Held for Sale and Discontinued Operations. Non-current assets (or disposal groups) are classified as held for sale when their carrying amount is to be recovered principally through a sale transaction rather than continuing use. In order to be classified as held for sale, the asset must be available for immediate sale in its present condition subject only to terms that are usual and customary, and the sale must be highly probable. Non-current assets (or disposal groups) held for sale are measured at the lower of carrying amount and fair value less cost to sell. Assets and liabilities classified as held for sale are presented separately in the consolidated balance sheet. Management judgement is required in determining whether the IFRS 5 held for sale classification criteria are met, in particular whether the sale is highly probable and expected to qualify for recognition as a completed sale within 12 months of classification. This assessment requires consideration of how committed management is to the sales plan, the likelihood of obtaining regulatory or other external approvals which is often required for sales of banking operations and how committed the buyer is to complete the sales transaction within the agreed timelines.

Disclosure of analysis of credit risk profile by internal PD band for loans and advances at amortised cost, contingent liabilities and loan commitments	The below tables represent credit risk profiles by PD grade for loans and advances at amortised cost, contingent liabilities and loan commitments. Stage 1 higher risk assets, presented gross of associated collateral held, are of weaker credit quality but have not significantly deteriorated since origination. IFRS 9 Stage 1 and Stage 2 classification is not dependent solely on the absolute probability of default but on elements that determine a Significant Increase in Credit Risk, including relative movement in probability of default since initial recognition. There is therefore no direct relationship between credit quality and IFRS 9 stage classification.

Historical correlations between losses are taken into account in making these assessments. The high and low VaR figures reported for each category did not necessarily occur on the same day as the high and low VaR reported as a whole. Consequently, a diversification effect balance for the high and low VaR figures would not be meaningful and is therefore omitted from the above table.
Disclosure of contractual maturity of financial assets and liabilities	The table below provides detail on the contractual maturity of all financial instruments and other assets and liabilities. Derivatives (other than those designated in a hedging relationship) and trading portfolio assets and liabilities are included in the ‘not more than one month’ column at their fair value. Liquidity risk on these items is not managed on the basis of contractual maturity since these items are not held for settlement according to such maturity and will frequently be settled before contractual maturity at fair value. Derivatives designated in a hedging relationship are included according to their contractual maturity.
