Disclosure of credit risk exposure [abstract]
Other disclosures - Risk Management and Principal Risks	Credit risk management (audited) The risk of loss to the Group from the failure of clients, customers or counterparties, including sovereigns, to fully honour their obligations to the Group, including the whole and timely payment of principal, interest, collateral and other receivables. Overview The credit risk that the 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, fair value through other comprehensive income (FVOCI) 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 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 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 entities, 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 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; 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; and review and validation of credit risk measurement models. The credit risk management teams in each legal entity are accountable to the relevant Legal Entity CRO, who reports to the 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 a legal entity Senior Credit Officer. For exposures in excess of the legal entity Senior Credit Officer’s authority, approval by Group Senior Credit Officer/Board Risk Committee is also required. The Group Credit Risk Committee, attended by legal entity Senior Credit Officers, provides a formal mechanism for the Group Senior Credit Officer to exercise the highest level of credit authority over the most material Group single name exposures. Credit risk mitigation The 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 Group’s normal practice is, on a legal entity basis, 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 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 motor vehicles and other physical assets; second lien charges over residential property; and finance lease receivables • derivatives: the Group also often seeks to enter into a margin agreement (e.g. Credit Support Annex) with counterparties with which the 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 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 two 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. + Detailed policies are in place to appropriately recognise and record credit risk mitigation. For more information, refer to pages 118 to 120 of the Barclays PLC Pillar 3 Report 2022 (unaudited). Governance and oversight of ECLs under IFRS 9 The Group’s organisational structure and internal governance processes oversee the estimation of ECL across several areas, including: i) setting requirements in policy, including key assumptions and the application of key judgements; ii) the design and execution of models; and iii) review of ECL results. i) Impairment policy requirements are set and reviewed regularly, at a minimum annually, to maintain adherence to accounting standards. Key judgements inherent in policy, including the estimated life of revolving credit facilities and the quantitative criteria for assessing the significant increase in credit risk (SICR), are separately supported by analytical study. In particular, the quantitative thresholds used for assessing SICR are subject to a number of internal validation criteria, particularly in retail portfolios where thresholds decrease as the origination Probability of Default (PD) of each facility increases. Key policy requirements are also typically aligned to the Group’s credit risk management strategy and practices, for example, wholesale customers that are risk managed on an individual basis are assessed for ECL on an individual basis upon entering Stage 3; furthermore, key internal risk management indicators of high risk are used to set SICR policy, for example, retail customers identified as high risk account management are automatically deemed to have met the SICR criteria. ii) ECL is estimated in line with internal policy requirements using models which are validated by a qualified independent party to the model development area, the Independent Validation Unit (IVU), before first use and on a regular basis, at a minimum every three years. Each model is designated an owner who is responsible for: • model maintenance: monitoring of model performance including backtesting by comparing predicted ECL versus flow into stage 3 and coverage ratios; proposing material changes for independent IVU approval; and recalibrating model parameters on more timely data • proposing post-model adjustments (PMA) to address model weaknesses or to account for situations where known or expected risk factors and information have not been considered in the modelling process. All PMAs relating to model deficiencies, regardless of value are approved by IVU for a set time period. PMAs representing Expert Judgement are validated by Risk, as the second line of defence and approved for a set time period. The most material PMAs are also approved by the CRO. Models must also assess ECL across a range of future economic conditions. These economic scenarios are generated via an independent model and ultimately set by the Senior Scenario Review Committee. Economic scenarios are regenerated at a minimum twice annually but more frequently if deemed appropriate, and also to align with the Group’s medium term planning exercise. Each model used in the estimation of ECL, including key inputs, are governed by a series of internal controls, which include the validation of completeness and accuracy of data in golden source systems, documented data transformations and documented lineage of data transfers between systems. i) The Group Impairment Committee, formed of members from both Finance and Risk and attended by both the Group Finance Director and the Group CRO, is responsible for overseeing impairment policy and practice across the Group and will approve impairment results. Reported results and key messages are communicated to the BAC, which has an oversight role and provides challenge of key assumptions, including the basis of the scenarios adopted. Impairment results are then factored into management decision making, including but not limited to, business planning, risk appetite setting and Market risk management (audited) The risk of loss arising from potential adverse changes in the value of the 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 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 Barclays International 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 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 BRC recommends market risk appetite to the Board for their approval. The Market Risk Principal Risk Lead (PR Lead) is responsible for the Market Risk Control Framework and, under delegated authority from the Group CRO, agrees with the business CROs a limit framework within the context of the approved market risk appetite. The Market Risk Committee (MRC) reviews and makes recommendations concerning the 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 PR Lead and attendees include the business heads of market risk and business aligned market risk managers. In addition to MRC, the Corporate and Investment Bank Risk Committee (‘CIBRC’) 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 Barclays International and meets weekly, covering current market events, notable market risk exposures, and key risk topics. New business initiatives are generally socialised at CIBRC before any changes to risk appetite or associated limits are considered in other governance committees. The head of each business is accountable for all market risks associated with its activities, while the head of the market risk team covering each business is responsible for implementing the risk control framework for market risk. For more information on market risk management, refer to the Barclays PLC Pillar 3 Report 2022 (unaudited). 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 the market risk performance section for a review of management VaR. Treasury and capital risk management This comprises: Liquidity risk: The risk that the 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 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 Group’s pension plans. Interest rate risk in the banking book: The risk that the Group is exposed to capital or income volatility because of a mismatch between the interest rate exposures of its (non-traded) assets and liabilities. The Treasury function manages treasury and capital risk exposure on a day-to-day basis with the Group Treasury Committee acting as the principal management body. 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. Liquidity risk management (audited) Overview The efficient management of liquidity is essential to the Group 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 risk appetite as expressed by the Barclays PLC Board. The liquidity risk appetite is monitored against 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 Board. The framework established by Treasury and Capital Risk is designed to deliver the appropriate term and structure of funding, consistent with the liquidity risk appetite set by the Board. The framework incorporates a range of ongoing business management tools to monitor, limit and stress test the Group’s balance sheet, contingent liabilities and the recovery plan. Limit setting and transfer pricing are tools 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 Group’s obligations as they fall due. The Board approves the Group funding plan, internal stress tests, regulatory stress test results, recovery plan and liquidity risk appetite. The Group Treasury Committee is responsible for monitoring and managing liquidity risk in line with the Group’s funding management objectives, funding plan and risk appetite. The 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 BRC reviews the risk profile, and reviews liquidity risk appetite at least annually and the impact of stress scenarios on the Group funding plan/forecast in order to agree the Group’s projected funding abilities. Capital risk management (audited) Overview Capital risk is managed through ongoing monitoring and management of the capital position, regular stress testing and a robust capital governance framework. The objectives of the framework are to maintain adequate capital for the Group and 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. Organisation, roles and responsibilities Treasury has the primary responsibility for managing and monitoring capital adequacy. The Treasury and Capital Risk function provides oversight of capital risk. Production of the Barclays 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 Group and 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 Group’s objectives. The Board approves the Group capital plan, internal stress tests and results of regulatory stress tests, and the Group recovery plan. The Group Treasury Committee is responsible for monitoring and managing capital risk in line with the Group’s capital management objectives, capital plan and risk frameworks. The Treasury and Capital Risk Committee monitors and reviews the capital risk profile and control environment, providing second line oversight of the management of capital risk. The BRC reviews the risk profile, and reviews risk appetite at least annually and the impact of stress scenarios on the Group capital plan/forecast in order to agree the Group’s projected capital adequacy. Local management assures compliance with an entity’s minimum regulatory capital requirements by reporting to local Asset and Liability Committees (ALCOs) with oversight by the Group Treasury Committee, as required. In 2022, Barclays complied with all regulatory minimum capital requirements. Pension risk The 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 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 Group could be required or might choose to make extra contributions to the pension fund. The Group’s main defined benefit scheme was closed to new entrants in 2012.

Also included are stage allocation of off-balance sheet loan commitments and financial guarantee contracts by gross exposure, impairment allowance and coverage as at 31 December 2022. Impairment allowance under IFRS 9 considers both the drawn and the undrawn counterparty exposure. For retail portfolios, the total impairment allowance is allocated to gross loans and advances to the extent allowance does not exceed the drawn exposure and any excess is reported on the liabilities side of the balance sheet as a provision. For wholesale portfolios, impairment allowance on undrawn exposure is reported on the liability side of the balance sheet as a provision.

Disclosure of objectives, policies and processes for managing capital [abstract]
Significant accounting policies	Significant accounting policies 1. Reporting entity Barclays PLC is a public company limited by shares registered in England under company number 48839, having its registered office at 1 Churchill Place, London, E14 5HP. These financial statements are prepared for Barclays PLC and its subsidiaries (the Group) under Section 399 of the Companies Act 2006. The Group is a major global financial services provider engaged in retail banking, 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 Group, and the separate financial statements of Barclays PLC, have been prepared in accordance with UK-adopted international accounting standards. The consolidated financial statements of the Group, and the separate financial statements of Barclays PLC, have also been prepared in accordance with 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. 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. 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. These financial statements are stated in millions of Pounds Sterling (£m), the functional currency of Barclays PLC. The financial statements have been prepared for Barclays PLC and its subsidiaries (the Group) under Section 399 of 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 Group and the 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 includes a review of a working capital report (WCR). The WCR is used by the Board to assess the future performance of the Group and that it has the resources in place that are required to meet its ongoing regulatory requirements. The assessment is based upon business plans which contain future projections of profitability taken from the 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 Group could experience. The WCR showed that the 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 Directors concluded that there was a reasonable expectation that the Group and parent company 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 Group prepares financial statements in accordance with IFRS. The Group’s significant 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 Group applies IFRS 10 Consolidated financial statements. The consolidated financial statements combine the financial statements of Barclays PLC and all its subsidiaries. Subsidiaries are entities over which Barclays PLC has control. The Group has control over another entity when the 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. The assessment of control is based on the consideration of all facts and circumstances. The Group reassesses whether it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control. Intra-group transactions and balances are eliminated on consolidation. Consistent accounting policies are used throughout the Group for the purposes of the consolidation. Changes in ownership interests in subsidiaries are accounted for as equity transactions if they occur after control has already been obtained and they do not result in loss of control. As the consolidated financial statements include partnerships where the 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 34. (ii) Foreign currency translation The Group applies IAS 21 The Effects of Changes in Foreign Exchange Rates. 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. Non-monetary foreign currency balances in relation to items measured in terms of historical cost are carried at historical transaction date exchange rates. Non-monetary foreign currency balances in relation to items measured at fair value are translated using the exchange rate at the date when the fair value was measured. The 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 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 The Group applies IFRS 9 Financial Instruments to the recognition, classification and measurement, and derecognition of financial assets and financial liabilities and the impairment of financial assets. The Group applies the requirements of IAS 39 Financial Instruments: Recognition and Measurement for hedge accounting purposes. Recognition The 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 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. In assessing whether contractual cash flows are SPPI compliant, interest is defined as consideration primarily for the time value of money and the credit risk of the principal outstanding. The time value of money is defined as the element of interest that provides consideration only for the passage of time and not consideration for other risks or costs associated with holding the financial asset. 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 and (iii) features that could modify the time value of money. Financial assets are measured at amortised cost if they are held within a business model whose objective is to hold financial assets in order to collect contractual cash flows, and their contractual cash flows represent SPPI. Financial assets are measured at fair value through other comprehensive income if they are held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets, and their contractual cash flows represent SPPI. Other financial assets are measured at fair value through profit and loss. There is an option to make an irrevocable election on initial recognition for non-traded equity investments to be measured at fair value through other comprehensive income, in which case dividends are recognised in profit or loss, but gains or losses are not reclassified to profit or loss upon derecognition, and the impairment requirements of IFRS 9 do not apply. The accounting policy for each type of financial asset or liability is included within the relevant note for the item. The Group’s policies for determining the fair values of the assets and liabilities are set out in Note 17. Derecognition The 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 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 reward have been transferred or retained, where control over the asset has been lost. Financial liabilities are derecognised 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. Transactions in which the Group transfers assets and liabilities, portions of them, or financial risks associated with them can be complex and it may not be obvious whether substantially all of the risks and rewards have been transferred. It is often necessary to perform a quantitative analysis. Such an analysis compares the 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 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 Group obtains such loans or cash collateral, in exchange for the transfer of collateral. The 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 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 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 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 The Group applies IAS 32, Financial Instruments: Presentation, to determine whether funding is either a financial liability (debt) or equity. Issued financial instruments or their components are classified as liabilities if the contractual arrangement results in the 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) Changes in the basis for determining contractual cash flows resulting from interest rate benchmark reform A change in the basis of determining the contractual cash flows of a financial instrument that is required by interest rate benchmark reform is accounted for by updating the effective interest rate, without the recognition of an immediate gain or loss. This practical expedient is only applied where (1) the change to the contractual cash flows is necessary as a direct consequence of the reform and (2) the new basis for determining the contractual cash flows is economically equivalent to the previous basis. For changes made in addition to those required by the interest rate benchmark reform, the practical expedient is applied first, after which the normal IFRS 9 requirements for modifications of financial instruments is applied. Refer to Note 14 for further details regarding hedge accounting policies in respect of interest rate benchmark reform. Refer to Note 41 for further disclosure related to interest rate benchmark reform. (vi) 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. Repurchase and reverse repurchase agreements are not considered to be part of cash equivalents. Investments in debt securities at amortised cost, presented within loans and advances on the balance sheet, are deemed to be investing activities for the purposes of the cash flow statement, except those instruments considered to be cash equivalents. Debt securities issued and redeemed are considered to be operating activities, except qualifying eligible liabilities that satisfy regulatory requirements for MREL instruments (or have previously satisfied these requirements since 2019 when they came into effect), which are considered to be financing activities. 5. New and amended standards and interpretations The accounting policies adopted have been consistently applied. Future accounting developments The following accounting standards have been issued by the IASB but are not yet effective: IFRS 17 – Insurance contracts In May 2017, the IASB issued IFRS 17 Insurance Contracts, a comprehensive new accounting standard for insurance contracts covering recognition and measurement, presentation and disclosure. IFRS 17 will replace IFRS 4 Insurance Contracts that was issued in 2005. In June 2020, the IASB published amendments to IFRS 17, to include scope exclusion for certain credit card contracts and similar contracts that provide insurance coverage, the optional scope exclusion for loan contracts that transfer significant insurance risk, and the clarification that only financial guarantees issued are in scope of IFRS 9. IFRS 17 applies to all types of insurance contracts (i.e. life, non-life, direct insurance and reinsurance), regardless of the type of entities that issue them, as well as to certain guarantees and financial instruments with discretionary participation features. A few scope exceptions will apply. IFRS 17 is effective for accounting periods beginning on or after 1 January 2023. The Group does not expect the impact of IFRS 17 to be material. 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 of 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 twelve 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. Disclosure of Accounting Policies - Amendments to IAS 1 and IFRS Practice Statement 2 In February 2021 the IASB issued amendments to IAS 1 that require entities to disclose their material accounting policies rather than their significant accounting policies. The amendments to IFRS Practice Statement 2 provide guidance on the concept of materiality and its application to accounting policy information. Under the amendments, accounting policy information is material if, when considered together with other information included in an entity’s financial statements, it can reasonably be expected to influence decisions that the primary users of general purpose financial statements make on the basis of those financial statements. The amendments are effective for annual periods beginning on or after 1 January 2023, and will be applied from that date. Definition of Accounting Estimate - Amendments to IAS 8 In February 2021 the IASB issued amendments to IAS 8 that replace the definition of a change in accounting estimates with a definition of accounting estimates. Under the new definition, accounting estimates are clarified as monetary amounts in financial statements that are subject to measurement uncertainty. Where an entity's accounting policy requires an item to be measured at monetary amounts that cannot be observed directly, it should develop an accounting estimate to achieve this objective. The amendments are effective for annual periods beginning on or after 1 January 2023, and will be applied from that date. 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. Critical accounting estimates and judgements are disclosed in: ▪ Credit impairment charges on page 342 ▪ Tax on page 346 ▪ Fair value of financial instruments on page 362 ▪ Goodwill and intangible assets on page 379 ▪ Pensions and post-retirement benefit obligations on page 400 ▪ Provisions including conduct and legal, competition and regulatory matters on page 383 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 211 213 222 262 ▪ Market risk on pages 213 263 264 ▪ Treasury and Capital risk – liquidity on pages 214 266 275 ▪ Treasury and Capital risk – capital on pages 214 276 283 These disclosures are covered by the Audit opinion (included on pages 320 322

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 and financial assets at fair value through other comprehensive income, and 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 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 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. 2022 2021 2020 £m £m £m Cash and balances at central banks 2,916 184 275 Loans and advances at amortised cost 13,376 9,540 10,180 Fair value through other comprehensive income 1,963 550 776 Negative interest on liabilities 208 248 68 Other 633 718 593 Interest and similar income 19,096 11,240 11,892 Deposits at amortised cost (3,573) (561) (1,030) Debt securities in issue (3,240) (1,340) (1,360) Subordinated liabilities (530) (507) (670) Negative interest on assets (208) (374) (344) Other (973) (385) (366) Interest and similar expense (8,524) (3,167) (3,770) Net interest income 10,572 8,073 8,122 Interest and similar income presented above represents interest revenue calculated using the effective interest method. Costs to originate credit card balances of £786m (2021: £652m; 2020: £698m) have been amortised to interest and similar income during the year. Interest and similar income includes £59m (2021: £37m; 2020: £40m) accrued on impaired loans. Other interest expense includes £56m (2021: £64m; 2020:£70m) relating to IFRS 16 lease interest expenses.

Fee and commission income (expense) [abstract]
Net fee and commission income	Net fee and commission income Accounting for net fee and commission income The Group applies IFRS 15 Revenue from Contracts with Customers. IFRS 15 establishes a five-step model governing revenue recognition. The five-step model requires the Group to (i) identify the contract with the customer, (ii) identify each of the performance obligations included in the contract, (iii) determine the amount of consideration in the contract, (iv) allocate the consideration to each of the identified performance obligations and (v) recognise revenue as each performance obligation is satisfied. The Group recognises fee and commission income charged for services provided by the Group as and when performance obligations are satisfied, for example, on completion of the underlying transaction. Where the contractual arrangements also result in the 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 Group and operating segments, in accordance with IFRS 15. The below table includes a total for fees in scope of IFRS 15. Refer to Note 2 for more detailed information about operating segments. 2022 Barclays UK Barclays International Head Office Total £m £m £m £m Fee type Transactional 1,084 3,256 — 4,340 Advisory 161 964 — 1,125 Brokerage and execution 256 1,521 — 1,777 Underwriting and syndication — 2,037 — 2,037 Other 59 153 3 215 Total revenue from contracts with customers 1,560 7,931 3 9,494 Other non-contract fee income — 143 — 143 Fee and commission income 1,560 8,074 3 9,637 Fee and commission expense (319) (2,713) (6) (3,038) Net fee and commission income 1,241 5,361 (3) 6,599 2021 Barclays UK Barclays International Head Office Total £m £m £m £m Fee type Transactional 871 2,572 — 3,443 Advisory 172 1,096 1 1,269 Brokerage and execution 228 1,135 — 1,363 Underwriting and syndication — 3,425 — 3,425 Other 74 182 3 259 Total revenue from contracts with customers 1,345 8,410 4 9,759 Other non-contract fee income — 121 — 121 Fee and commission income 1,345 8,531 4 9,880 Fee and commission expense (218) (1,983) (5) (2,206) Net fee and commission income 1,127 6,548 (1) 7,674 2020 Barclays UK Barclays International Head Office Total £m £m £m £m Fee type Transactional 810 2,353 — 3,163 Advisory 159 693 2 854 Brokerage and execution 212 1,173 — 1,385 Underwriting and syndication — 2,867 — 2,867 Other 71 173 9 253 Total revenue from contracts with customers 1,252 7,259 11 8,522 Other non-contract fee income — 119 — 119 Fee and commission income 1,252 7,378 11 8,641 Fee and commission expense (308) (1,754) (8) (2,070) Net fee and commission income 944 5,624 3 6,571 Fee types Transactional Transactional fees are service charges on deposit accounts, cash management services fees and transactional processing fees. 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 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 the underwriting and syndication fees are loan commitment fees, when the drawdown is not probable, which are not presented as part of the carrying value of the loan in accordance with IFRS 9. Such commitment fees are recognised over time through to the contractual maturity of the commitment. Contract assets and contract liabilities The Group had no material contract assets or contract liabilities as at 31 December 2022 (2021: £nil; 2020: £nil). Impairment of fee receivables and contract assets During 2022, there have been no material impairments recognised in relation to fees receivable and contract assets (2021: £nil; 2020: £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 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 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 Group expects that incremental costs of obtaining a contract such as success fee and commission fees paid are recoverable and therefore capitalise such contract costs. Capitalised contract costs net of amortisation as at 31 December 2022 are £198m (2021: £154m; 2020: £141m). Capitalised contract costs are amortised over the customer relationship period depending on the transfer of services to which the asset pertains. In 2022, the amount of amortisation was £47m (2021: £36m; 2020: £36m) and there was no impairment loss recognised in connection with the capitalised contract costs (2021: £nil; 2020: £nil).

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 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 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 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 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 reassigned 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. The Group uses a five-scenario model to calculate ECL. An external consensus forecast is assembled from key sources, including HM Treasury (short and medium-term forecasts) and Bloomberg (based on median of economic forecasts), which forms the Baseline scenario. In addition, two adverse scenarios (Downside 1 and Downside 2) and two favourable scenarios (Upside 1 and Upside 2) are derived, with associated probability weightings. The adverse scenarios are calibrated to a broadly similar severity to the Group's internal stress tests and stress scenarios provided by regulators whilst also considering IFRS 9 specific sensitivities and non-linearity. The favourable scenarios are designed to reflect plausible upside risks to the Baseline scenario which are broadly consistent with the economic narrative approved by the Senior Scenario Review Committee. All scenarios are regenerated at a minimum semi-annually. The scenarios include key economic variables (including GDP, unemployment, House Price Index (HPI) and base rates in both the UK and US markets) and expanded variables using statistical models based on historical correlations. The upside and downside shocks are designed to evolve over a five-year stress horizon, with all five scenarios converging to a steady state after approximately seven years. The methodology for estimating probability weights for each of the scenarios involves a comparison of the distribution of key historical UK and US macroeconomic variables against the forecast paths of the five scenarios. The methodology works such that the baseline (reflecting current consensus outlook) has the highest weight and the weights of adverse and favourable scenarios depend on the deviation from the baseline; the further from the baseline, the smaller the weight. A single set of five scenarios is used across all portfolios and all five weights are normalised to equate to 100%. The same scenarios used in the estimation of expected credit losses are also used to inform Barclays' internal planning. The impacts across the portfolios are different because of the sensitivities of each of the portfolios to specific macroeconomic variables, for example, mortgages are highly sensitive to house prices, and credit cards and unsecured consumer loans are highly sensitive to unemployment. 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. Uncollectable loans are written off against the related allowance for loan impairment on completion of the 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 Group may enter into a financial guarantee contract which requires the issuer of such contract to reimburse the 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 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. Note 1 sets out details for changes in the basis of determining the contractual cash flows of a financial instrument that are required by interest rate benchmark reform. 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 revolving 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 The regulatory Basel Committee of Banking Supervisors (BCBS) ECL calculations are leveraged for IFRS 9 modelling but adjusted for key differences which include: ▪ BCBS requires 12 month through the economic cycle losses whereas IFRS 9 requires 12 months or lifetime point in time losses based on conditions at the reporting date and multiple forecasts of the future economic conditions over the expected lives; ▪ IFRS 9 models do not include certain conservative BCBS model floors and downturn assessments and require discounting to the reporting date at the original EIR rather than using the cost of capital to the date of default; ▪ Management adjustments are made to modelled output to account for situations where known or expected risk factors and information have not been considered in the modelling process, for example forecast economic scenarios for uncertain political events; and ▪ ECL is measured at the individual financial instrument level, however a collective approach where financial instruments with similar risk characteristics are grouped together, with apportionment to individual financial instruments, is used where effects can only be seen at a collective level, for example for forward-looking information. For the IFRS 9 impairment assessment, the Group’s risk models are used to determine the PD, LGD and EAD. For Stage 2 and 3, the Group applies lifetime PDs but uses 12 month PDs for Stage 1. The ECL drivers of PD, EAD and LGD are modelled at an account level which considers vintage, among other credit factors. Also, the assessment of significant increase in credit risk is based on the initial lifetime PD curve, which accounts for the different credit risk underwritten over time. 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 definition 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 Group’s experience of managing credit risk. The determination of expected life is most material for Barclays' 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. The impairment charge reflected in the income statement for retail portfolios is £976m (2021: £289m release; 2020: £3,116m charge) of the total impairment charge on loans and advances and off-balance sheet loan commitments and financial guarantee contracts. 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 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. The impairment charge reflected in the financial statements in relation to wholesale portfolios is £207m (2021: £346m release; 2020: £1,569m charge) of the total impairment charge on loans and advances and off-balance sheet loan commitments and financial guarantee contracts. Further information on impairment allowances, impairment charges, management adjustments to models for impairment, measurement uncertainty, sensitivity analysis and related credit information is set out within the Credit risk performance section. Temporary adjustments to calculated IFRS9 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 page 237 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. 2022 2021 2020 Impairment Charges/(Releases) Recoveries and reimburse-ments a Total Impairment Charges/(Releases) Recoveries and reimburse-ments Total Impairment Charges/(Releases) Recoveries and reimburse-ments Total £m £m £m £m £m £m £m £m £m Loans and advances at amortised cost 1,428 (263) 1,165 (361) 240 (121) 4,308 (399) 3,909 Off-balance sheet loan 18 — 18 (514) — (514) 776 — 776 Total 1,446 (263) 1,183 (875) 240 (635) 5,084 (399) 4,685 Cash collateral and settlement balances 28 — 28 (4) — (4) 2 — 2 Financial instruments at fair value through other comprehensive income 9 9 (8) — (8) 2 — 2 Other financial assets measured at cost — — — (6) — (6) 149 — 149 Credit impairment charges/(releases) 1,483 (263) 1,220 (893) 240 (653) 5,237 (399) 4,838 Note a Recoveries and reimbursements includes a net increase in amounts recoverable from financial guarantee contracts held with third parties of £199m (2021: £(306)m) and cash recoveries of previously written off amounts of £64m (2021: £66m).

Major components of tax expense (income) [abstract]
Tax	Tax Accounting for income taxes The 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 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 Group’s tax returns. The 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 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 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 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 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. Details on the recognition of deferred tax assets are provided in this note. 2022 2021 2020 £m £m £m Current tax charge/(credit) Current year 1,045 1,417 1,255 Adjustments in respect of prior years (444) 317 31 601 1,734 1,286 Deferred tax charge/(credit) Current year 235 (352) (830) Adjustments in respect of prior years 203 (244) 148 438 (596) (682) Tax charge 1,039 1,138 604 In 2022 the adjustments in respect of prior years are principally a result of various steps taken in the US and UK tax groups that have affected the timing of the tax deductibility of expenditure related to fixed assets. Across the Barclays Bank PLC’s US Branch Tax Group and US Intermediate Holding Company Tax Group ('IHC Tax Group'), elections have been made in 2022 to advance tax deductions in relation to fixed assets that would otherwise have arisen in later periods. Those elections resulted in a current tax credit in respect of prior years of £556m and a deferred tax charge in respect of prior years of a similar amount. In the UK Tax Group various tax claims and elections will have the effect of deferring the timing of deductions related to plant and machinery and this has resulted in a current tax charge in respect of prior years of £167m and a deferred tax credit in respect of prior years of 213m. 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 Group’s profit before tax. 2021 2021 2020 2020 £m % £m % £m % Profit before tax 7,012 8,194 3,065 Tax charge based on the standard UK corporation tax rate of 19% (2021: 19%; 2020: 19% ) 1,332 19.0 % 1,557 19.0 % 582 19.0 % Impact of profits/losses earned in territories with different statutory rates to the UK (weighted average tax rate is 21.4% (2021: 22.4%; 2020: 25.1% )) 167 2.4 % 277 3.4 % 188 6.1 % Recurring items: Non-creditable taxes including withholding taxes 126 1.8 % 134 1.6 % 109 3.5 % Banking surcharge a and other items 101 1.4 % 83 1.0 % 6 0.2 % Non-deductible expenses 51 0.7 % 80 1.0 % 48 1.6 % Impact of UK bank levy being non-deductible 33 0.5 % 32 0.4 % 57 1.9 % Impact of Barclays Bank PLC's overseas branches being taxed both locally and in the UK 17 0.2 % 25 0.3 % 25 0.8 % Tax adjustments in respect of share-based payments 13 0.2 % (5) (0.1 %) 26 0.8 % Non-taxable gains and income (135) (1.9 %) (198) (2.4 %) (185) (6.0 %) Changes in recognition of deferred tax and effect of unrecognised tax losses (146) (2.1 %) (140) (1.7 %) (123) (4.0 %) Tax relief on payments made under AT1 instruments (172) (2.4 %) (149) (1.8 %) (165) (5.4 %) Adjustments in respect of prior years (241) (3.4 %) 73 0.9 % 179 5.8 % Tax relief on holdings of inflation-linked government bonds (556) (7.9 %) (169) (2.1 %) (23) (0.8 %) Non-recurring items: Remeasurement of UK deferred tax assets due to tax rate changes 346 4.9 % (462) (5.6 %) (118) (3.8 %) Non-deductible provisions for investigations and litigation 93 1.3 % — — 5 0.2 % Non-deductible provisions for UK customer redress 10 0.1 % — — (7) (0.2 %) Total tax charge 1,039 14.8 % 1,138 13.9 % 604 19.7 % Note a Banking surcharge includes the impact of the 8% UK banking surcharge rate on profits/losses and tax adjustments relating to UK banking entities. Factors driving the effective tax rate The effective tax rate of 14.8% is lower than the UK corporation tax rate of 19% primarily due to tax relief on holdings of inflation-linked government bonds, beneficial prior year adjustments, tax relief on payments made under AT1 instruments and the utilisation of unrecognised tax losses in the period. These factors, which have each decreased the effective tax rate, are partially offset by adjustments for the remeasurement of UK deferred tax assets as a result of the enactment during 2022 of a reduction in the banking surcharge rate to 3% from 1 April 2023 and profits earned outside the UK being taxed at local statutory tax rates that are higher than the UK tax rate. The 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 Group operates in. In its Autumn Statement held in November 2022, the UK Government confirmed that, as currently enacted, the banking surcharge rate will be reduced from 8% to 3% from 1 April 2023. UK deferred tax assets as at 31 December 2022 are measured at this rate, having been remeasured when the 3% rate was substantively enacted in 2022. The statutory tax rate applicable to banks' UK profits will therefore be 28% (comprising a rate of 25% for corporation tax and of 3% for banking surcharge) from 1 April 2023. The OECD and G20 Inclusive Framework on Base Erosion and Profit Shifting announced plans to introduce a global minimum tax rate of 15% and the OECD issued model rules in 2021. During 2022 further OECD guidance has been released and draft legislation to implement the global minimum tax regime has been published by the UK Government. The UK Government has stated that it intends to enact legislation in 2023 to apply for accounting periods beginning on or after 31 December 2023. The Group has reviewed the published OECD model rules and further guidance along with the draft UK legislation and has been assessing the expected impact ahead of the implementation of the new regime. The Group will review further guidance as well as new legislation expected to be released by governments implementing this new tax regime and continue to assess the potential impact. In the USA, the Inflation Reduction Act was enacted in August 2022. The Act does not include changes to the US corporate income tax rate or to US international tax provisions included in the previously proposed Build Back Better Act but does introduce a corporate alternative minimum tax on adjusted financial statements income, effective from 1 January 2023. Further regulations and guidance are expected to be published in 2023, however the Group’s preliminary view is that the alternative minimum tax is not expected to materially increase the Group’s effective tax rate. The Group will review future guidance when it is published and continue to monitor other legislative developments and assess the potential impact. Tax in the consolidated statement of comprehensive income The tax relating to each component of other comprehensive income can be found in the consolidated statement of comprehensive income . The total amount recognised in relation to the remeasurement of UK deferred tax through other comprehensive income was a £28m charge (2021: £111m). Tax included directly in equity Tax included directly in equity comprises a £1m credit (2021: £58m) 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: 2022 2021 £m £m UK Tax Group 4,925 2,183 IHC Tax Group 1,094 1,004 Barclays Bank PLC's US Branch Tax Group 482 1,002 Other (outside the UK and US tax groups) 490 430 Deferred tax asset 6,991 4,619 Deferred tax liability (16) (37) Net deferred tax 6,975 4,582 US deferred tax assets in the IHC and US Branch Tax Groups The deferred tax asset in the IHC Tax Group of £1,094m (2021: £1,004m) includes £21m (2021: £1m) 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 £482m (2021: £1,002m) relates entirely to temporary differences. In relation to the IHC Tax Group, these temporary differences include £434m (2021: £301m) 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 these amounts will be fully recovered before expiry. UK Tax Group deferred tax asset The deferred tax asset in the UK Tax Group of £4,925m (2021: £2,183m) includes £1,535m (2021: £1,098m) 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 that these losses will be fully recovered. Other deferred tax assets (outside the UK and US tax groups) The deferred tax asset of £490m (2021: £430m) in other entities within the Group includes £90m (2021: £121m) 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 £490m (2021: £430m), an amount of £33m (2021: £9m) 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 assets expected to be recovered after more than 12 months is £8,155m (2021: £5,886m). The amount of deferred tax liability expected to be settled after more than 12 months is £1,864m (2021: £1,778m). 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 Deferred tax assets have not been recognised in respect of gross deductible temporary differences of £111m (2021: £110m), unused tax credits of £323m (2021: £283m), and gross tax losses of £22,537m (2021: £22,835m). The tax losses include capital losses of £3,935m (2021: £3,981m). Of these tax losses, £149m (2021: £63m) expire within five years, £401m (2021: £370m) expire within six to ten years, £10,393m (2021: £10,529m) expire within 11 to 20 years and £11,594m (2021: £11,873m) 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. Group investments in subsidiaries, branches and associates Deferred tax is not recognised in respect of the value of the Group's investments in subsidiaries, branches and associates where the 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 £852m (2021: £858m).

When calculating the diluted earnings per share, the weighted average number of shares in issue is adjusted for the effects of all expected dilutive potential ordinary shares held in respect of Barclays PLC, totalling 534m (2021: 435m) shares. The total number of share options outstanding, under schemes considered to be potentially dilutive, was 789m (2021: 688m). These options have strike prices ranging from £0.84 to £1.66. Of the total number of employee share options and share awards at 31 December 2022, 27m (2021: 5m) were anti-dilutive. The 652m decrease (2021: 315m decrease) in the basic weighted average number of shares is primarily due to the impact of the share buy-back programmes completed in the year.

Dividends on ordinary shares	Dividends on ordinary shares The Directors have approved a total dividend in respect of 2022 of 7.25p per ordinary share of 25p each. The full year dividend for 2022 of 5.00p per ordinary share will be paid on 31 March 2023 to shareholders on the Share Register on 24 February 2023. On 31 December 2022, there were 15,871m ordinary shares in issue. The financial statements for the year ended 31 December 2022 do not reflect this dividend, which will be accounted for in shareholders’ equity as an appropriation of retained profits in the year ending 31 December 2023. The Directors have confirmed their intention to initiate a share buyback of up to £500m after the balance sheet date. The proposed share buyback is expected to commence in the first quarter of 2023. The financial statements for the year ended 31 December 2022 do not reflect the impact of the proposed share buyback, which will be accounted for as and when shares are repurchased by the Company. The 2022 financial statements include the 2022 interim dividend of £364m (2021: £339m); a full year dividend declared in relation to 2021 of £664m (2020: £173m) and two share buyback programmes totalling £1,500m (2021: £1,200m). Dividends and share buybacks are funded out of distributable reserves.

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 statement 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 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 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 17.

Derivative financial instrument

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 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. This includes terms included in a contract or financial liability (the host), which, had it been a standalone contract, would have met the definition of a derivative. If these are separated from the host, i.e. when the economic characteristics of the embedded derivative are not closely related with those of the host contract and the combined instrument is not measured at fair value through profit or loss, then they are accounted for in the same way as derivatives. For financial assets, the requirements are whether the financial assets contain contractual terms that give rise on specified dates to cash flows that are SPPI, and consequently the requirements for accounting for embedded derivatives are not applicable to financial assets. Hedge accounting The Group applies the requirements of IAS 39 Financial Instruments: Recognition and Measurement for hedge accounting purposes. The 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 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. The Group applies the ‘Amendments to IFRS 9, IAS 39 and IFRS 7 Interest Rate Benchmark Reform’ issued in September 2019 (the Phase 1 amendments). The amendments provide temporary relief from applying specific hedge accounting requirements to hedging relationships directly affected by IBOR (‘Interbank Offered Rates’) reform. The reliefs have the effect that IBOR reform should not generally cause hedge accounting to terminate. However, any hedge ineffectiveness continues to be recorded in the income statement. Furthermore, the amendments set out triggers for when the reliefs will end, which include the uncertainty arising from interest rate benchmark reform no longer being present. In summary, the reliefs provided by the Phase 1 amendments are: ▪ When considering the ‘highly probable’ requirement, the Group has assumed that the IBOR interest rates upon which our hedged items are based do not change as a result of IBOR Reform. ▪ In assessing whether the hedge is expected to be highly effective on a forward-looking basis the Group has assumed that the IBOR interest rates upon which the cash flows of the hedged items and the interest rate swaps that hedge them are based are not altered by IBOR reform. ▪ The Group will not discontinue hedge accounting during the period of IBOR-related uncertainty solely because the retrospective effectiveness falls outside the required 80–125% range. ▪ The Group has not recycled the cash flow hedge reserve relating to the period after the reforms are expected to take effect. ▪ The Group has assessed whether the hedged IBOR risk component is a separately identifiable risk only when it first designates a hedged item in a fair value hedge and not on an ongoing basis. The Group also applies the ‘Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16 Interest Rate Benchmark Reform – Phase 2’ issued in August 2020. The Phase 2 amendments provide relief when changes are made to hedge relationships as a result of the interest rate benchmark reform. In summary, the reliefs provided by the Phase 2 amendments are: ▪ Under a temporary exception, the Group has considered that changes to the hedge designation and hedge documentation due to the interest rate benchmark reform would not constitute the discontinuation of the hedge relationship nor the designation of a new hedging relationship. ▪ In respect of the retrospective hedge effectiveness assessment, the Group may elect, on a hedge-by-hedge basis, to reset the cumulative fair value changes to zero when the exception to the retrospective assessment ends (Phase 1 relief). Any hedge ineffectiveness will continue to be measured and recognised in full in profit or loss. ▪ The Group has deemed the amounts accumulated in the cash flow hedge reserve to be based on the alternative benchmark rate (on which the hedge future cash flows are determined) when there is a change in basis for determining the contractual cash flows. ▪ For hedges of groups of items (such as those forming part of a macro cash flow hedging strategy), the amendments provide relief for items within a designated group of items that are amended for changes directly required by the reform. ▪ In respect of whether a risk component of a hedged item is separately identifiable, the amendments provide temporary relief to entities to meet this requirement when an alternative risk free rate (RFR) financial instrument is designated as a risk component. These amendments allow the Group upon designation of the hedge to assume that the separately identifiable requirement is met if the Group reasonably expects the RFR risk will become separately identifiable within the next 24 months. The Group applies this relief to each RFR on a rate-by-rate basis and starts when the Group first designates the RFR as a non-contractually specified risk component. 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 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 Group’s investment in the operation.

Interest rate risk also includes exposure to inflation risk for certain types of investments. ▪ Currency risk – arises due to assets or liabilities being denominated in different currencies than the functional currency of the relevant entity. 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 Group does not hedge inflation risk that arises from other activities. In order to hedge these risks, the Group uses the following hedging instruments: ▪ Interest rate derivatives to swap interest rate exposures 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 Group designates risk components of hedged items as follows: ▪ Benchmark interest rate risk as a component of interest rate risk, such as the LIBOR or Risk Free Rate (RFR) component. ▪ Inflation risk as a contractually specified component of a debt instrument. ▪ Spot 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. Following market-wide interest rate benchmark reform, sensitivity to risk-free rates is considered to be the predominant interest rate risk and therefore the hedged items (which often reference risk-free or similar 'overnight' rates) change in fair value on a proportionate basis with reference to this risk. In respect of many of the 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 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 CET1 capital. The Group mitigates this by matching the CET1 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. ▪ The effects of the reforms to IBOR because these might take effect at a different time and have a different impact on hedged items and hedging instruments. The Group's risk exposure continues, in part, to be affected by interest rate benchmark reform. In most cases, hedged items and hedging instruments are expected to transition to relevant risk-free rates at the end of their current cash flow period. USD LIBOR, Canadian Dollar Offerred Rate (CDOR) and Singapore Swap Offered Rate (SOR) linked hedge accounting relationships are still exposed to uncertainty regarding the precise timing and effects of benchmark reform. USD LIBOR and SOR benchmarks will cease to be published after 30 June 2023, CDOR - after 28 June 2024, but certain hedged items and hedging instruments continue to contractually reference these benchmarks beyond the cessation date.

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 remeasured 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 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 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). Gains or losses on the derecognition of these equity securities are not transferred to profit or loss. These assets are also not subject to the impairment requirements and therefore no amounts are recycled to the income statement. Where the Group has not made the irrevocable election to present subsequent changes in the fair value of the instrument in other comprehensive income, equity securities are measured at fair value through profit or loss. 2022 2021 £m £m Debt securities and other eligible bills 64,832 60,798 Equity securities a 8 902 Loans and advances 222 53 Financial assets at fair value through other comprehensive income 65,062 61,753 Note

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 P&L. 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 P&L. On derecognition of the financial liability no amount relating to own credit risk is recycled to the income statement. The 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 Group on the basis of its fair value, or includes terms that have substantive derivative characteristics (Note 14).

Fair value of financial instrum

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 values 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. All financial instruments are initially recognised at fair value on the date of initial recognition (including transaction costs, other than financial instruments held at fair value through profit or loss) and depending on the subsequent classification of the financial asset or liability, may continue to be held at fair value either through profit or loss or other comprehensive income. The fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Wherever possible, fair value is determined by reference to a quoted market price for that instrument. For many of the 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. The best evidence of an instrument’s fair value on initial recognition is typically the transaction price. However, if fair value can be evidenced by comparison with other observable current market transactions in the same instrument, or is based on a valuation technique whose inputs include only data from observable markets, then the instrument should be recognised at the fair value derived from such observable market data. 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 model 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 371 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. Valuation IFRS 13 Fair value measurement requires an entity to classify its assets and liabilities 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 classification. 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. 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 the Group’s 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 2022 2021 Valuation technique using Valuation technique using Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total As at 31 December £m £m £m £m £m £m £m £m Trading portfolio assets 62,478 64,855 6,480 133,813 80,926 63,828 2,281 147,035 Financial assets at fair value through the income statement 5,720 198,723 9,125 213,568 5,093 177,167 9,712 191,972 Derivative financial assets 10,054 287,152 5,174 302,380 6,150 252,412 4,010 262,572 Financial assets at fair value through other comprehensive income 20,704 44,347 11 65,062 22,009 39,706 38 61,753 Investment property — — 5 5 — — 7 7 Total assets 98,956 595,077 20,795 714,828 114,178 533,113 16,048 663,339 Trading portfolio liabilities (44,128) (28,740) (56) (72,924) (27,529) (26,613) (27) (54,169) Financial liabilities designated at fair value (133) (270,454) (1,050) (271,637) (174) (250,376) (410) (250,960) Derivative financial liabilities (10,823) (272,434) (6,363) (289,620) (6,571) (244,253) (6,059) (256,883) Total liabilities (55,084) (571,628) (7,469) (634,181) (34,274) (521,242) (6,496) (562,012) The following table shows the Group’s Level 3 assets and liabilities that are held at fair value disaggregated by product type: Level 3 assets and liabilities held at fair value by product type 2022 2021 Assets Liabilities Assets Liabilities £m £m £m £m Interest rate derivatives 2,362 (2,858) 1,091 (1,351) Foreign exchange derivatives 1,513 (1,474) 376 (374) Credit derivatives 290 (603) 323 (709) Equity derivatives 1,009 (1,428) 2,220 (3,625) Corporate debt 1,677 (49) 1,205 (21) Reverse repurchase and repurchase agreements 37 (434) 13 (172) Non-asset backed loans 9,949 — 6,405 — Private equity investments 1,291 (8) 1,095 (6) Other a 2,667 (615) 3,320 (238) Total 20,795 (7,469) 16,048 (6,496) Note a Other includes commercial real estate loans, asset backed loans, funds and fund-linked products, issued debt, Government and Government sponsored debt, asset backed securities, equity cash products and investment property. 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 the nature of the valuation techniques used, as well as the availability and reliability of observable proxy and historical data and the 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. Foreign exchange derivatives Description: Derivatives linked to the foreign exchange (FX) market. The category includes FX forward contracts, FX swaps and FX options. The majority are traded as over the counter (OTC) derivatives. Valuation: FX derivatives are valued using industry standard and bespoke models depending on the product type. Valuation inputs include FX rates, interest rates, FX volatilities, interest rate volatilities, FX interest rate correlations and others as appropriate. Observability: FX correlations, forwards and volatilities are generally 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. Credit derivatives Description: Derivatives linked to the credit spread of a referenced entity, index or basket of referenced entities or a pool of referenced assets (e.g. a securitised product). The category includes single name and index credit default swaps (CDS) and total return swaps (TRS). Valuation: CDS are valued on industry standard models using curves of credit spreads as the principal input. Credit spreads are observed directly from broker data, third party vendors or priced to proxies. Observability : CDS contracts referencing entities that are actively traded are generally considered observable. Other valuation inputs are considered observable if products with significant sensitivity to the inputs are actively traded in a liquid market. Unobservable valuation inputs are generally determined with reference to recent transactions or inferred from observable trades of the same issuer or similar entities. 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 bonds 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. Non-asset backed loans Description: Largely made up of fixed rate loans. Valuation: Fixed rate loans are valued using models that discount expected future cash flows based on interest rates and loan spreads. Observability: Within this loan population, the loan spread is generally unobservable. Unobservable loan spreads are determined by incorporating funding costs, the level of comparable assets such as gilts, issuer credit quality and other factors. 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. Other Description: Other includes commercial real estate loans, asset backed loans, funds and fund-linked products, issued debt, government sponsored debt, asset backed securities, equity cash products and investment property. Assets and liabilities reclassified between Level 1 and Level 2 During the period, there were no material transfers between Level 1 and Level 2 (2021: 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 period. The table shows gains and losses and includes amounts for all financial assets and liabilities that are held at fair value transferred to and from Level 3 during the period. 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 i) an increase or decrease in observable market activity related to an input or ii) 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 1/100th of 1%; for example, 150 basis points equals 1.5%. c 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 17-2159bps (2021: 32-1,848bps). The 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 movement 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 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. Non-asset backed loans includes a portfolio of loans extended to clients within the Group’s leveraged finance business. Leveraged finance loans are originated where Barclays provide 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. Non-asset backed loans contains a portfolio primarily consisting of long-dated fixed rate loans extended to counterparties in the UK Education, Social Housing and Local Authority sectors (ESHLA). The loans are categorised as Level 3 in the fair value hierarchy due to their illiquid nature and the significance of unobservable loan spreads to the valuation. Valuation uncertainty arises from the long-dated nature of the portfolio, the lack of secondary market in the loans and the lack of observable loan spreads. The majority of ESHLA loans are to borrowers in heavily regulated sectors that are considered extremely low credit risk, and have a history of near zero defaults since inception. While the overall loan spread range is from 50bps to 589bps (2021: 31bps to 1,552bps), the vast majority of spreads are concentrated towards the bottom end of this range, with 88% of the loan notional being valued with spreads less than 200bps consistently for both years. In general, a significant increase in loan spreads in isolation will result in a fair value decrease for a loan. EBITDA multiple EBITDA multiple is the ratio of the valuation of the investment to the earnings before interest, taxes, depreciation and amortisation. In general, a significant increase in the multiple will result in a fair value increase for an investment. Earnings multiple Earnings or Revenue multiple is the ratio of the valuation of the investment to the earnings or revenue. In general, a significant increase in the multiple will result in a fair value increase for an investment.

Offsetting financial assets and financial liabilities [Abstract]
Offsetting financial assets and financial liabilities	Offsetting financial assets and financial liabilities In accordance with IAS 32 Financial Instruments: Presentation, t he 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 are not intended to represent the Group’s actual exposure to credit risk, as a variety of credit mitigation strategies are employed in addition to netting and collateral arrangements.

Settlements assets and liabilities have been offset amounting to £24,250m (2021: £22,837m). b Financial collateral of £45,981m (2021: £40,485m) was received in respect of derivative assets, including £34,547m (2021: £34,598m) of cash collateral and £11,434m (2021: £5,887m) of non-cash collateral. Financial collateral of £26,639m (2021: £34,321m) was placed in respect of derivative liabilities, including £25,222m (2021: £32,031m) of cash collateral and £1,417m (2021: £2,290m) of non-cash collateral. The collateral amounts are limited to net balance sheet exposure so as to not include overcollateralisation. c This column includes contractual rights of set-off that are subject to uncertainty under the laws of the relevant jurisdiction. d 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’. e Reverse repurchase agreements and other similar secured lending of £165,457m (2021: £148,241m) is split by fair value £164,681m (2021: £145,014m) and amortised cost £776m (2021: £3,227m). Repurchase agreements and other similar secured borrowing of £199,798m (2021: £196,412m) is split by fair value £172,746m (2021: £168,060m) and amortised cost £27,052m (2021: £28,352m). Derivative 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. Repurchase and reverse 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 and collateral arrangements and other credit risk mitigation strategies used by the Group are further explained in the Credit risk management section.

Loans and advances and deposits at amortised cost
Loans and advances and deposits at amortised cost	Loans and advances and deposits at amortised cost Accounting for loans and advances and deposits held at amortised cost Loans and advances to customers and banks, customer accounts, debt securities and most financial liabilities, are held at amortised cost. That is, the initial fair value (which is normally the amount advanced or borrowed) is adjusted for repayments and the amortisation of coupon, fees and expenses to represent the effective interest rate of the asset or liability. Balances deferred on-balance sheet as effective interest rate adjustments are amortised to interest income over the life of the financial instrument to which they relate. Financial assets that are held in a business model to collect the contractual cash flows and that contain contractual terms that give rise on specified dates to cash flows that are SPPI, are measured at amortised cost. The carrying value of these financial assets at initial recognition includes any directly attributable transaction costs. Refer to Note 1 for details on ‘solely payments of principal and interest’. In determining whether the business model is a ‘hold to collect’ model, the objective of the business model must be to hold the financial asset to collect contractual cash flows rather than holding the financial asset for trading or short-term profit taking purposes. While the objective of the business model must be to hold the financial asset to collect contractual cash flows this does not mean the Group is required to hold the financial assets until maturity. When determining if the business model objective is to collect contractual cash flows the Group will consider past sales and expectations about future sales.

Disclosure of detailed information about property, plant and equipment [abstract]
Property, plant and equipment	Property, plant and equipment Accounting for property, plant and equipment The Group applies IAS 16 Property Plant and Equipment and IAS 40 Investment Properties. 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. The Group uses the following annual rates in calculating depreciation: Annual rates in calculating depreciation Depreciation rate Freehold land Not depreciated Freehold buildings and long-leasehold property (more than 50 years to run) 2-3.3% Leasehold property over the remaining life of the lease (less than 50 years to run) 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.

Leases [Abstract]
Leases	Leases Accounting for leases IFRS 16 applies to all leases with the exception of licences of intellectual property, rights held by licensing agreements within the scope of IAS 38 Intangible Assets, service concession arrangements, leases of biological assets within the scope of IAS 41 Agriculture and leases of minerals, oil, natural gas and similar non-regenerative resources . IFRS 16 includes an accounting policy choice for a lessee to elect not to apply IFRS 16 to remaining assets within the scope of IAS 38 Intangible Assets which the Group has decided to apply. When the Group is the lessee, it is required to recognise both: ▪ A lease liability, measured at the present value of remaining cash flows on the lease, and ▪ A right 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. The lease liability is remeasured when there is a change in one of the following: ▪ Future lease payments arising from a change in an index or rate; ▪ The Group’s estimate of the amount expected to be payable under a residual value guarantee; or ▪ The Group’s assessment of whether it will exercise a purchase, extension or termination option. When the lease liability is remeasured, a corresponding adjustment is made to the carrying amount of the ROU asset, or is recorded in the income statement if the carrying amount of the ROU asset has been reduced to nil. On the balance sheet, the ROU assets are included within property, plant and equipment and the lease liabilities are included within other liabilities. The Group applies 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 Group is 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. When the lease is deemed a finance lease, the leased asset is not held on the balance sheet; instead a finance lease receivable is recognised representing the minimum lease payments receivable under the terms of the lease, discounted at the rate of interest implicit in the lease. When the lease is deemed an operating lease, the lease income is recognised on a straight-line basis over the period of the lease unless another systematic basis is more appropriate. The Group holds the leased assets on balance sheet within property, plant and equipment. As a Lessor Finance lease receivables are included within loans and advances at amortised cost. The following table sets out a maturity analysis of lease receivables, showing the lease payments to be received after the reporting date. 2022 2021 Gross investment in finance lease receivables Future finance income Present value of minimum lease payments Unguaranteed residual values Gross investment in finance lease receivables Future finance income Present value of minimum lease payments Unguaranteed residual values £m £m £m £m £m £m £m £m Not more than one year 14 (1) 13 — 29 (3) 26 — One to two years 9 (1) 8 — 19 (2) 17 — Two to three years 2 — 2 — 6 — 6 — Three to four years 1 — 1 — 2 — 2 — Four to five years 1 — 1 — 1 — 1 — Over five years 1 — 1 — 1 — 1 — Total 28 (2) 26 — 58 (5) 53 — Barclays Asset Finance provided leasing and other asset finance facilities across a broad range of asset types to business and individual customers.There is no impairment allowance for finance lease receivables in current and previous year. The Group does not have any material operating leases as a lessor. Finance lease income Finance lease income is included within interest income. The following table shows amounts recognised in the income statement during the year. 2022 2021 £m £m Finance income from net investment in lease 2 21 Profit on sales — 1 As a Lessee The Group leases various offices, branches and other premises under non-cancellable lease arrangements to meet its operational business requirements. In some instances, Barclays will sublease property to third parties when it is no longer needed to meet business requirements. Currently, Barclays does not have any material subleasing arrangements. ROU asset balances relate to property leases only. Refer to Note 20 for the carrying amount of ROU assets. The total expenses recognised during the year for short term leases were £1m (2021: £3m). The portfolio of short term leases to which Barclays is exposed at the end of the year is not dissimilar to the expenses recognised in the year.

Currently, Barclays has 401 (2021: 609) leases out of the total 896 (2021: 1,111) leases which have variable lease payment terms based on market-based pricing adjustments. Of the gross cash flows identified above, £1,087m (2021: £1,196m) is attributable to leases with some degree of variability predominately linked to market-based pricing adjustments. ▪ Extension and termination options: The table above represents Barclays' 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 £516m (2021: £434m) for leases where Barclays is highly expected to exercise an early termination option. However, there is no significant impact where Barclays is expected to exercise an extension option. In 2022, the Group recorded a one-off gain of £88m from sale and leaseback (2021: £33m). The Group does not have any restrictions or covenants imposed by the lessor on its property leases which restrict its businesses.

Intangible assets and goodwill [abstract]
Goodwill and intangible assets	Goodwill and intangible assets Accounting for goodwill and intangible assets Goodwill The carrying value of goodwill is determined in accordance with IFRS 3 Business Combinations and IAS 36 Impairment of Assets . Goodwill arising on the acquisition of subsidiaries represents the excess of the fair value of the purchase consideration over the fair value of the 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 a 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 CGU's fair value if this is higher. Intangible assets Intangible assets other than goodwill are accounted for in accordance with IAS 38 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 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 a 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 a Exceptions to the above rate relate to useful lives of certain core banking platforms that are assessed individually and, if appropriate, amortised over longer periods ranging from 10 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.

Goodwill is allocated to CGUs for the purpose of impairment testing. The review of goodwill for impairment involves calculating a value in use (VIU) valuation which is compared to the carrying value of a CGU associated with the goodwill to determine whether any impairment has occurred. This includes the identification of independent CGUs across the organisation and the allocation of goodwill to those CGUs. The calculation of a value in use contains a high degree of uncertainty in estimating the future cash flows and the rates used to discount them. Key judgements include determining the carrying value of the CGU, the cash flows and discount rates used in the calculation. ▪ The cash flow forecasts used by management involve judgement and are based upon a view of the future prospects of the business and market conditions at the point in time the assessment is prepared. The estimation of cash flows is sensitive to the periods for which detailed forecasts are available and to assumptions regarding long-term sustainable cash flows . ▪ The discount rates applied to the future cash flows also involve judgement as they can have a significant impact on the valuation. The discount rates used are compared to market participants to ensure that they are appropriate and based on an estimated cost of equity for each CGU. ▪ The choice of a terminal growth rate used to determine the present value of the future cash flows of the CGUs is also a judgement that can impact the outcome of the assessment. The terminal growth rate and discount rates used may vary due to external market rates and economic conditions that are beyond management’s control, including the potential effect of climate change . Further details of some of the key judgements are set out below. 2022 impairment review The 2022 impairment review was performed during Q4 2022. In comparison to the prior year, there is an expectation of an increasing interest rate environment which would impact favourably on the Barclays UK CGUs. A detailed assessment has been performed, 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 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 consider a market participant would be required to hold and retain to support business growth. The goodwill held across the Group has been allocated to the CGU where it originated, based upon historical records. The intangible asset balances are allocated to the CGUs based upon their expected usage of these assets. Cash flows The five-year cash flows used in the calculation are based on the formally agreed medium-term plans approved by the Board. These are prepared using macroeconomic assumptions which management consider reasonable and supportable, and reflect business agreed initiatives for the forecast period. The macroeconomic assumptions underpinning the medium term plan were determined in August 2022 and management has considered whether there are subsequent significant changes in those assumptions which would adversely impact the results of the impairment review. As required by IAS 36, all estimates of future cash flows exclude cash inflows or outflows that are expected to arise from restructuring initiatives where a constructive obligation to carry out the plan does not yet exist. In line with prior year treatment, the Education, Social Housing and Local Authority (ESHLA) portfolio has been excluded from the Business Banking CGU cash flows. This is a legacy loan portfolio which was previously within the Non-Core bank and was not part of the business to which the goodwill relates. As such, the cash flows relating to this portfolio have been excluded from the Business Banking VIU calculation. 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 have in previous years identified the cost of equity associated with market participants that closely resemble the Group's CGUs and adjusted them for tax to arrive at the pre-tax equivalent rate. This method assumed a static rate of tax that was applicable to the pre-tax cash flows of the CGU. The cost of equity without adjusting for the tax rate has been used as the discount rate in the 2022 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 the pre-tax method adjusted for varying tax rates. Using the resultant VIU the equivalent pre-tax discount rate has been calculated. The range of equivalent pre-tax discount rates applicable across the CGUs range from 14.1% to 16.5% (2021: 12.5% to 15.1%). 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 Group operates. Inflation rates are used as an approximation of future growth rates and form the basis of the terminal growth rates applied. The terminal growth rate used is 2.0% (2021: 2.0%). Outcome of goodwill and intangibles review The Personal Banking and Business Banking CGUs carry the majority of the Group’s goodwill balance, predominantly as a consequence of the Woolwich acquisition. The goodwill within Personal Banking was £2,752m (2021: £2,752m), of which £2,501m (2021: £2,501m) was attributable to Woolwich, and within Business Banking was £629m (2021: £629m), fully attributable to Woolwich. The recoverable amount for both Personal Banking and Business Banking have increased in comparison to the 2021 impairment review, reflective of improvements in the interest rate and macroeconomic outlook. The largest portion of the Group’s intangible assets sit within the Cards and Payments CGU, part of Barclays International with an allocation of £1,531m (2021: £1,351m). Based on management’s plans and assumptions the value in use exceeds the carrying value of the CGUs and no impairment has been indicated. The outcome of the impairment review for Personal Banking, Business Banking and Cards and Payments are set out below: Cash generating unit Tangible equity Goodwill Intangibles Carrying value Value in use Value in use exceeding carrying value Value in use exceeding carrying value 2021 £m £m £m £m £m £m £m Personal Banking 5,091 2,752 928 8,771 13,438 4,667 1,489 Business Banking 1,549 629 216 2,394 9,017 6,623 3,623 Cards and Payments 3,780 229 1,531 5,540 7,138 1,598 1,025 Total 10,420 3,610 2,675 16,705 29,593 12,888 6,137 Sensitivity of key judgements The CGUs are sensitive to possible adverse changes in the key assumptions that support the recoverable amount: Cash flows: The medium-term plans used to determine the cash flows used in the VIU calculation rely on macroeconomic forecasts, including interest rates, GDP and unemployment, and forecast levels of market and client activity. 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. Given the current level of economic uncertainty, a 10% reduction in cash flows has been provided to show the sensitivity of the outcome to a change in these key assumptions. 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 have 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 and shows the impact of a 100 bps change 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 CGUs' 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 100 bps change in the terminal growth rate. 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. 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 is set out below: Cash generating unit Carrying value Value in use Value in use exceeding carrying value Discount rate Terminal growth rate Reduction in headroom Change required to reduce headroom to zero 100 bps increase in the discount rate 100 bps decrease in terminal growth rate 50 bps 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 % % % % Personal Banking 8,771 13,438 4,667 16.5 2.0 (944) (596) (279) (1,493) 6.9 (14.8) 8.4 (31.3) Cards and Payments 5,540 7,138 1,598 15.9 2.0 (724) (515) (287) (1,005) 2.5 (3.7) 2.8 (15.9) Total 14,311 20,576 6,265

Provisions

Provisions [abstract]
Provisions	Provisions Accounting for provisions The Group applies IAS 37 Provisions, Contingent Liabilities and Contingent Assets in accounting for non-financial liabilities. 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. Provision is made for the anticipated cost of restructuring, including redundancy costs, when an obligation exists; for example, when the 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. 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 complexity of such matters often requires the input of specialist professional advice in making assessments to produce estimates. Customer redress and legal, competition and regulatory matters are areas where a higher degree of professional judgement is required. 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 26 for more detail of legal, competition and regulatory matters.

Provisions expected to be recovered or settled within no more than 12 months after 31 December 2022 were £1,348m (2021: £1,754m). Onerous contracts Onerous contract provisions comprise an estimate of unavoidable costs involved with fulfilling the terms and conditions of contracts net of any expected benefits to be received. Redundancy and restructuring These provisions comprise the estimated cost of restructuring, including redundancy costs where an obligation exists. Additions made during the year relate to formal restructuring plans and have either been utilised, or reversed where total costs are now expected to be lower than the original provision amount. 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. For further information, refer to the Credit risk section for loan commitments and financial guarantees on page 230 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 Group’s business activities. Legal, competition and regulatory matters The 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, refer to Note 26. Sundry provisions This category includes provisions that do not fit into any of the other categories, such as fraud losses and dilapidation provisions.

Legal, competition and regulatory matters [Abstract]
Legal, competition and regulatory matters	Legal, competition and regulatory matters The 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 judgments in accordance with the relevant accounting policies applicable to Note 24, Provisions. We have not disclosed an estimate of the potential financial impact or effect on the 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 Group’s potential financial exposure in respect of those matters. Matters are ordered under headings corresponding to the financial statements in which they are disclosed. 1. Barclays PLC and Barclays Bank PLC Investigations into certain advisory services agreements FCA proceedings In 2008, Barclays Bank PLC and Qatar Holdings LLC entered into two advisory 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 £50m. Barclays PLC and Barclays Bank PLC contested the findings. In September 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 £50m on Barclays PLC and Barclays Bank PLC, the same penalty as in the Warning Notices. Barclays PLC and Barclays Bank PLC have referred the RDC’s findings to the Upper Tribunal for reconsideration. Investigations into LIBOR and other benchmarks and related civil actions Regulators and law enforcement agencies, including certain competition authorities, from a number of governments have conducted investigations relating to Barclays Bank PLC’s involvement in allegedly manipulating certain financial benchmarks, such as LIBOR. Various individuals and corporates in a range of jurisdictions have threatened or brought civil actions against the Group and other banks in relation to the alleged manipulation of LIBOR and/or other benchmarks. USD LIBOR civil actions The majority of the USD LIBOR cases, which have been filed in various US jurisdictions, have been consolidated for pre-trial purposes in the US District Court in the Southern District of New York (SDNY). The complaints are substantially similar and allege, among other things, that Barclays PLC, 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. Putative class actions and individual actions seek unspecified damages with the exception of one lawsuit, in which the plaintiffs are seeking no less than $100m in actual damages and additional punitive damages against all defendants, including Barclays Bank PLC. Some of the lawsuits also seek trebling of damages under the Antitrust Act and RICO. Barclays Bank PLC has previously settled certain claims. In 2022, Barclays Bank PLC also settled one further matter. The financial impact of the settlement is not material to the Group’s operating results, cash flows or financial position. Sterling LIBOR civil actions In 2016, two putative class actions filed in the SDNY against Barclays Bank PLC, BCI and other Sterling LIBOR panel banks alleging, among other things, that the defendants manipulated the Sterling LIBOR rate in violation of the Antitrust Act, CEA and RICO, were consolidated. The defendants’ motion to dismiss the claims was granted in 2018. The plaintiffs have appealed the dismissal. Japanese Yen LIBOR civil actions In 2012, a putative class action was filed in the SDNY against Barclays Bank PLC and other Japanese Yen LIBOR panel banks by a lead plaintiff involved in exchange-traded derivatives and members of the Japanese Bankers Association’s Euroyen Tokyo Interbank Offered Rate (Euroyen TIBOR) panel. The complaint alleges, among other things, manipulation of the Euroyen TIBOR and Yen LIBOR rates and breaches of the CEA and the Antitrust Act. In 2014, the court dismissed the plaintiff’s antitrust claims, and in 2020, the court dismissed the plaintiff’s remaining CEA claims. In 2015, a second putative class action, making similar allegations to the above class action, was filed in the SDNY against Barclays PLC, Barclays Bank PLC and BCI. Barclays and the plaintiffs have reached a settlement of $17.75m for both actions. A final court approval hearing has been scheduled for March 2023. SIBOR/SOR civil action In 2016, a putative class action was filed in the SDNY against Barclays PLC, Barclays Bank PLC, BCI and other defendants, alleging manipulation of the Singapore Interbank Offered Rate (SIBOR) and Singapore Swap Offer Rate (SOR). The plaintiffs and remaining defendants (which includes Barclays Bank PLC) reached a joint settlement to resolve this matter for $91m, which received final court approval in November 2022. This matter is now concluded. The financial impact of Barclays’ share of the joint settlement is not material to the Group’s operating results, cash flows or financial position. ICE LIBOR civil actions In 2019, several putative class actions were filed in the SDNY against a panel of banks, including Barclays PLC, Barclays Bank PLC, BCI, other financial institution defendants and Intercontinental Exchange Inc. and certain of its affiliates (ICE), asserting antitrust claims that the defendants manipulated USD LIBOR through the defendants’ submissions to ICE. These actions have been consolidated. The defendants’ motion to dismiss was granted in 2020 and the plaintiffs appealed. In February 2022, the dismissal was affirmed on appeal. The plaintiffs did not seek US Supreme Court review. This matter is now concluded. In August 2020, an ICE LIBOR-related action was filed by 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. The plaintiffs’ motion seeking, among other things, preliminary and permanent injunctions to enjoin the defendants from continuing to set LIBOR or enforce any financial instrument that relies in whole or in part on USD LIBOR was denied. The defendants’ motion to dismiss the case was granted in September 2022. The plaintiffs have filed an amended complaint, which the defendants have moved to dismiss. Non-US benchmarks civil actions There remains 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, Argentina and Israel relating to alleged manipulation of LIBOR and EURIBOR. Additional proceedings in other jurisdictions may be brought in the future. 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 have moved to dismiss the case. Foreign Exchange investigations and related civil actions The Group has been the subject of investigations in various jurisdictions in relation to certain sales and trading practices in the Foreign Exchange market. Settlements were reached in various jurisdictions in connection with these investigations, including the EU and US. The financial impact of any remaining ongoing investigations is not expected to be material to the Group’s operating results, cash flows or financial position. Various individuals and corporates in a range of jurisdictions have threatened or brought civil actions against the Group and other banks in relation to alleged manipulation of Foreign Exchange markets. US FX opt out civil action In 2018, Barclays Bank PLC and BCI settled a consolidated action filed in the SDNY, alleging manipulation of Foreign Exchange markets (Consolidated FX Action), for a total amount of $384m. Also in 2018, a group of plaintiffs, who opted out of the Consolidated FX Action, filed a complaint in the SDNY against Barclays PLC, Barclays Bank PLC, BCI and other defendants. Some of the plaintiffs’ claims were dismissed in 2020. Barclays PLC, Barclays Bank PLC, and BCI have reached a settlement in principle of all claims against them in the matter. The financial impact of this settlement is not material to the Group’s operating results, cash flows or financial position. 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 Group and all other defendants. The plaintiffs have filed an amended complaint. 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. Additional proceedings may be brought in the future. The above-mentioned proceedings include two purported 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 CAT refused to certify these claims in the first quarter of 2022 although the claimants have obtained permission to appeal and judicially review the CAT’s decisions. Also in 2019, a separate claim was filed in the UK in the High Court of Justice (High Court), and subsequently transferred to the CAT, by various banks and asset management firms against Barclays Bank PLC and other financial institutions alleging breaches of European and UK competition laws related to FX trading. This claim has been settled as part of the settlement in principle referred to under the US FX opt out civil action above. Metals-related civil actions A number of US civil complaints, each on behalf of a proposed class of plaintiffs, have been consolidated and transferred to the SDNY. The complaints allege that Barclays Bank PLC and other members of The London Gold Market Fixing Ltd. manipulated the prices of gold and gold derivative contracts in violation of the Antitrust Act and other federal laws. The parties reached a joint settlement to resolve this matter for $50m. The settlement received final court approval in August 2022. This matter is now concluded. The financial impact of Barclays’ share of the joint settlement is not material to the Group’s operating results, cash flows or financial position. A separate US civil complaint by a proposed class of plaintiffs against a number of banks, including Barclays Bank PLC, BCI and BX, alleging manipulation of the price of silver in violation of the CEA, the Antitrust Act and state antitrust and consumer protection laws, has been dismissed as against the Barclays entities. The plaintiffs have the option to seek the court’s permission to appeal. 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 actions There are two pending US Residential Mortgage-Backed Securities (RMBS) related civil actions 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. In one action, the Barclays defendants’ motion for summary judgment was granted in June 2022 and the plaintiffs’ R&W breach claim was dismissed. The plaintiffs are appealing the decision. The other repurchase action is pending. Barclays Bank PLC reached settlements to resolve two other repurchase actions, which have received final court approval. Payment of the settlement amounts was completed in July 2022. These matters are now concluded. The financial impact of the settlements is not material to the Group’s operating results, cash flows or financial position. In 2020, a civil litigation claim was filed in the New Mexico First Judicial District Court by the State of New Mexico against six banks, including BCI, on behalf of two New Mexico state pension funds and the New Mexico State Investment Council relating to legacy RMBS purchases. As to BCI, the complaint alleges that the funds purchased approximately $22m in RMBS underwritten by BCI. The parties have reached a joint settlement to resolve this matter for $32.5m. The settlement was paid in April 2022. The financial impact of BCI’s share of the joint settlement is not material to the Group’s operating results, cash flows or financial position. 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 March 2021. The plaintiffs filed an amended complaint. The defendants’ motion to dismiss the amended complaint was granted in March 2022. The plaintiffs are appealing this decision. 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. Supranational, Sovereign and Agency bonds civil actions Civil antitrust actions have been filed in the SDNY and Federal Court of Canada in Toronto against Barclays Bank PLC, BCI, BX, Barclays Capital Securities Limited and, with respect to the civil action filed in Canada only, 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. In one of the actions filed in the SDNY, the court granted the defendants’ motion to dismiss the plaintiffs’ complaint. The dismissal was affirmed on appeal; however, the district court subsequently informed the parties of a potential conflict. The matter was assigned to a new district court judge and the plaintiffs moved to vacate the dismissal order, which was denied. The plaintiffs’ time to appeal has expired and this matter is now concluded. The plaintiffs have voluntarily dismissed the other SDNY action. In the Federal Court of Canada action, the parties have reached a settlement in principle, which will require court approval. The financial impact of the settlement is not expected to be material to the 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. Two actions in state court have been filed by private plaintiffs on behalf of the states of Illinois and California. 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 November 2020 and June 2022. In the California action, the plaintiffs’ claims were dismissed in June 2021. The plaintiffs have appealed the dismissal. In the Illinois action, trial has been scheduled for August 2023. Odd-lot corporate bonds antitrust class action In 2020, BCI, together with other financial institutions, were named as defendants in a putative class action. 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 and the plaintiffs have appealed the dismissal. 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 class actions which were consolidated in the SDNY in 2016. The complaints allege the defendants conspired to prevent the development of exchanges for IRS and demand unspecified money damages. In 2018, trueEX LLC filed an antitrust class action in the SDNY against a number of financial institutions including Barclays PLC, Barclays Bank PLC and BCI based on similar allegations with respect to trueEX LLC’s development of an IRS platform. In 2017, Tera Group Inc. filed a separate civil antitrust action in the SDNY claiming that certain conduct alleged in the IRS cases also caused the plaintiff to suffer harm with respect to the Credit Default Swaps market. In 2018 and 2019, respectively, the court dismissed certain claims in both cases for unjust enrichment and tortious interference but denied motions to dismiss the federal and state antitrust claims, which remain pending. BDC Finance L.L.C. In 2008, BDC Finance L.L.C. (BDC) filed a complaint in the Supreme Court of the State of New York (NY Supreme Court), demanding damages of $298m, 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 April 2021, the trial court entered judgement in favour of Barclays Bank PLC for $3.3m and as yet to be determined legal fees and costs. BDC appealed. In January 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 have filed cross-motions on the scope of trial. The trial has been adjourned pending a decision on the motions and any subsequent appeal. In 2011, BDC’s investment advisor, BDCM Fund Adviser, LLC and its parent company, Black Diamond Capital Holdings, LLC, also sued Barclays Bank PLC and BCI in Connecticut State Court for unspecified damages allegedly resulting from Barclays Bank PLC’s conduct relating to the Master Agreement, asserting claims for violation of the Connecticut Unfair Trade Practices Act and tortious interference with business and prospective business relations. This case is currently stayed. Civil actions in respect of the US Anti-Terrorism Act There are a number of civil actions, on behalf of more than 4,000 plaintiffs, 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 in January 2023. The remaining EDNY actions are 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 any appeal on the dismissal of the first. Shareholder derivative action In November 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 Group. The shareholder 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 April 2021, which BCI and certain other defendants moved to dismiss. The motion to dismiss was granted in April 2022. The plaintiff is appealing the decision. Derivative transactions civil action In 2021, Vestia, a Dutch housing association, brought a claim against Barclays Bank PLC in the UK in the High Court in relation to a series of derivative transactions entered into with Barclays Bank PLC between 2008 and 2011, seeking damages of £329m. Barclays Bank PLC is defending the claim and has made a counterclaim. Timeshare loans, skilled person review, and associated matters In August 2020, the FCA granted an application by Clydesdale Financial Services Limited (CFS), which trades as Barclays Partner Finance and houses Barclays’ point-of-sale finance business, for a validation order with respect to certain loans to customers brokered between April 2014 and April 2016 by Azure Services Limited (ASL), a timeshare operator, which did not, at the point of sale, hold the necessary broker licence. As a condition to the validation order, the FCA required CFS to undertake a skilled person review of the assessment of affordability processes for the loans brokered by ASL (ASL Loans) as well as CFS’ policies and procedures for assessing affordability and oversight of brokers more generally, and dictated a remediation methodology in the event that ASL Loans did not pass the affordability test. The skilled person made a number of observations, some of which were adverse, about both current and historic affordability practices as well as current oversight practices. CFS is not required to conduct a full back book review but, following a review of certain cohorts of loans to determine historic affordability and/or broker oversight practices that may have caused customer harm, where harm is identified, CFS’ intention is to remediate. To date, CFS has identified a number of areas for remediation, but the scoping exercise is ongoing and remediation will only begin once the scoping exercise is complete. As at 31 December 2022, CFS booked a provision in respect of the expected remediation for these matters of £10.4m. Separately, and notwithstanding this, CFS decided in March 2022 to extend the proactive remediation of ASL Loans beyond those brokered between April 2014 and April 2016 to include the full portfolio of ASL Loans brokered between 2006 and 2018. In the first quarter of 2022, an additional customer remediation provision was recognised in relation to the remediation of the ASL Loans originated outside the April 2014 to April 2016 period. As at 31 December 2022, the provision recognised in relation to this matter by CFS is £183m. Remediation of the full portfolio of ASL Loans started in October 2022 and is expected to be completed in 2023. In addition, CFS completed a review of all other legacy timeshare retailers during 2022. No concerns were identified in relation to the majority of those retailers, but where concerns were identified, CFS’ intention is to remediate. As at 31 December 2022, the provision recognised in relation to this matter by CFS is £96m. Over-issuance of Securities in the US Barclays Bank PLC maintains a US shelf registration statement with the US Securities and Exchange Commission (SEC) in order to issue securities to US investors. In May 2017, Barclays Bank PLC lost its status as a “well-known seasoned issuer” (or WKSI) as a result of an SEC settlement order involving BCI. Due to its loss of WKSI status, Barclays Bank PLC was required to register a specified amount of securities to be issued under certain US shelf registration statements filed with the SEC. In March 2022, executive management became aware that Barclays Bank PLC had issued securities materially in excess of the set amount under its 2019 US shelf registration statement and subsequently became aware that securities had also been issued in excess of the set amount under the predecessor US shelf registration statement. The securities that were over-issued included structured notes and exchange traded notes (ETNs). Securities issued in excess of the amount registered were considered to be “unregistered securities” for the purposes of US securities laws, with certain purchasers of those securities having a right to recover, upon the tender of such security to Barclays Bank PLC, the consideration paid for such security with interest, less the amount of any income received, or to recover damages from Barclays Bank PLC if the purchaser sold the security at a loss (the Rescission Price). Barclays Bank PLC commenced its rescission offer on 1 August 2022, by which Barclays Bank PLC offered to repurchase the relevant affected securities for the Rescission Price (the Rescission Offer). The Rescission Offer expired on 12 September 2022. In September 2022, the SEC announced the resolution of its investigation of Barclays PLC and Barclays Bank PLC relating to the over-issuance of securities by Barclays Bank PLC under certain of its US shelf registration statements. Pursuant to the terms of the resolution, Barclays PLC and Barclays Bank PLC paid in the fourth quarter of 2022 a combined penalty of $200m (£165m 1 ), without admitting or denying the SEC’s findings. The SEC found that the independent Rescission Offer made by Barclays Bank PLC to holders of the relevant over-issued securities satisfied its requirements for disgorgement and related prejudgment interest. The Group is engaged with, and responding to inquiries and requests for information from, various other regulators who may seek to impose fines, penalties and/or other sanctions as a result of this matter. Furthermore, Barclays Bank PLC and/or its affiliates may incur costs and liabilities in relation to private civil claims which have been filed and may face other potential private civil claims, class actions or other enforcement actions in relation to this matter. By way of example, in September 2022, a purported class action claim was filed in the US District Court in Manhattan seeking to hold Barclays PLC and former and current executives responsible for declines in the prices of its American depositary receipts, which the plaintiffs claim occurred as a result of alleged misstatements and omissions in its public disclosures; and in February 2023, a claim was brought in a New York federal court by holders of a series of ETNs alleging 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. Following completion of the rescission offer on 12 September 2022, Barclays utilised a provision of £1,008m in settlement of valid structured note claims and paid a monetary penalty of $200m (£165m 1 ) to the SEC. A contingent liability exists in relation to civil claims or any further enforcement actions taken against Barclays Bank PLC and/or its affiliates, but Barclays Bank PLC is unable to assess the likelihood of liabilities that may arise out of such claims or actions. Any liabilities, claims or actions in connection with the over-issuance of securities under Barclays Bank PLC’s US shelf registration statements could have an adverse effect on the Group’s business, financial condition, results of operations and reputation as a frequent issuer in the securities markets. Note 1 Exchange rate USD/GBP 1.22 as at 30 June 2022. Investigation into the use of unapproved communications platforms In September 2022, the SEC and the Commodity Futures Trading Commission (CFTC) announced settlements with a number of financial institutions, including Barclays Bank PLC and BCI, of financial industry-wide investigations regarding compliance with record-keeping obligations in connection with business-related communications sent over unapproved electronic messaging platforms. The SEC and the CFTC found that Barclays Bank PLC and BCI failed to comply with their respective record-keeping rules, where such communications were sent or received by employees over electronic messaging platforms that had not been approved by the bank for business use by employees. As part of the settlement, in the third quarter of 2022, Barclays Bank PLC and BCI paid a combined $125m civil monetary penalty to the SEC and a $75m civil monetary penalty to the CFTC. There are also non-financial components to the settlements, including the retention of an independent compliance consultant and certain ongoing undertakings. This matter is now concluded. 2. Barclays PLC, Barclays Bank PLC and Barclays Bank UK PLC HM Revenue & Customs (HMRC) assessments concerning UK Value Added Tax In 2018, HMRC issued notices that have the effect of removing certain overseas subsidiaries that have operations in the UK from Barclays’ UK VAT group, in which group supplies between members are generally free from VAT. The notices have retrospective effect and correspond to assessments of £181m (inclusive of interest), of which Barclays would expect to attribute an amount of approximately £128m to Barclays Bank UK PLC and £53m to Barclays Bank PLC. HMRC’s decision has been appealed to the First Tier Tribunal (Tax Chamber). Local authority civil actions concerning LIBOR Following settlement by Barclays Bank PLC of various governmental investigations concerning certain benchmark interest rate submissions referred to above in ‘Investigations into LIBOR and other benchmarks and related civil actions’, in the UK, certain local authorities brought claims in 2018 against Barclays Bank PLC and Barclays Bank UK PLC asserting that they entered into loans between 2006 and 2008 in reliance on misrepresentations made by Barclays Bank PLC in respect of its conduct in relation to LIBOR. Barclays Bank PLC and Barclays Bank UK PLC were successful in their applications to strike

The Junior Undated Floating Rate Notes are floating rate notes where rates are fixed periodically in advance based on the related market rate. The Junior Undated Floating Rate Notes are repayable at the option of Barclays Bank PLC, in whole, on any interest payment date.

All dated subordinated liabilities externally issued by Barclays Bank 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 its equity. The dated subordinated liabilities externally issued by other subsidiaries are similarly subordinated as the external subordinated liabilities issued by Barclays Bank PLC. Interest Interest on the Floating Rate Notes is fixed periodically in advance, based on the related market rates. Interest on Fixed Rate Notes is set by reference to market rates at the time of issuance and fixed until maturity.

After the respective call dates, in the event that they are not redeemed, the interest rates will be reset and fixed until maturity based on a market rate. Interest on the 5.088% Fixed-to-Floating Rate Subordinated Callable Notes is fixed until the call date. After the call date, in the event that they are not redeemed, the interest rate will reset periodically in advance based on market rates. Repayment Those subordinated liabilities with a call date are repayable at the option of the issuer 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. The remaining dated subordinated liabilities outstanding at 31 December 2022 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 require, in the case of Barclays PLC and Barclays Bank PLC, the prior consent of the PRA, or in the case of the overseas issues, the approval 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.

Barclays Bank PLC and protective rights of non-controlling interests Barclays PLC holds 100% of the voting rights of Barclays Bank PLC. As at 31 December 2022, Barclays Bank PLC has in issue preference shares and Upper Tier 2 instruments. These are non-controlling interests to the Group. A fixed coupon rate is attached to all Upper Tier 2 instruments until the initial call date, with the exception of the 9% Bonds, which are fixed for the life of the issue and the Series 1 and Series 2 Undated Notes, which are floating rate at rates fixed periodically in advance based on market rates. After the initial call date, in the event they are not redeemed, coupon payments in relation to the 6.125% Undated Notes are fixed periodically in advance for five-year periods based on market rates. Coupon payments for all other Upper Tier 2 instruments are at rates fixed periodically in advance based on market rates. The payment of preference share dividends and Upper Tier 2 coupons are typically at the discretion of Barclays Bank PLC, except for coupon payments that become compulsory where Barclays PLC has declared or paid a dividend on ordinary shares, or in certain cases, any class of preference shares, in the preceding six-month period. Coupons not paid become payable in each case if such a dividend is subsequently paid or in certain other circumstances. No dividend or coupon payments may be made unless Barclays Bank PLC satisfies a specified solvency test. Under the terms of these instruments, Barclays PLC may not pay dividends on ordinary shares until a dividend or coupon is next paid on these instruments or the instruments are redeemed or purchased by Barclays Bank PLC. There are no restrictions on Barclays Bank PLC’s ability to remit capital to the Parent as a result of these issued instruments. Preference share redemptions are typically at the discretion of Barclays Bank PLC. Upper Tier 2 instruments are repayable, at the option of Barclays Bank PLC generally in whole at the initial call date and on any subsequent coupon payment date or, in the case of the 6.125% Undated Notes on any fifth anniversary after the initial call date. In addition, each issue of Upper Tier 2 instruments is repayable, at the option of Barclays Bank PLC, in whole for certain tax reasons, either at any time, or on an interest payment date. There are no events of default except non-payment of principal or mandatory interest.

Classes of employee benefits expense [abstract]
Staff costs	Staff costs Accounting for staff costs The Group applies IAS 19 Employee benefits in its accounting for most of the components of staff costs. Short-term employee benefits – salaries, accrued performance costs and social security are recognised over the period in which the employees provide the services to which the payments relate. Performance costs – recognised to the extent that the Group has a present obligation to its employees that can be measured reliably and are recognised over the period of service that employees are required to work to qualify for the payments. Deferred cash and share awards are made to employees to incentivise performance over the period employees provide services. To receive payment under an award, employees must provide service over the vesting period. The period over which the expense for deferred cash and share awards is recognised is based upon the period employees consider their services contribute to the awards. For past awards, the Group considers that it is appropriate to recognise the awards over the period from the date of grant to the date that the awards vest. In relation to awards granted from 2017, the Group, taking into account the changing employee understanding surrounding those awards, considered it appropriate for expense to be recognised 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 32 and Note 33 respectively. 2022 2021 2020 £m £m £m Incentive awards granted: Current year bonus 1,241 1,278 1,090 Deferred bonus 549 667 490 Total incentive awards granted 1,790 1,945 1,580 Reconciliation of incentive awards granted to income statement charge: Less: deferred bonuses granted but not charged in current year (388) (457) (335) Add: current year charges for deferred bonuses from previous years 399 280 293 Other differences between incentive awards granted and income statement charge 35 (23) (34) Income statement charge for performance costs 1,836 1,745 1,504 Other income statement charges: Salaries 4,732 4,290 4,322 Social security costs 714 619 613 Post-retirement benefits a 563 539 519 Other compensation costs 504 431 479 Total compensation costs b 8,349 7,624 7,437 Other resourcing costs: Outsourcing 607 357 342 Redundancy and restructuring (7) 296 102 Temporary staff costs 113 109 102 Other 190 125 114 Total other resourcing costs 903 887 660 Total staff costs 9,252 8,511 8,097 Notes a Post-retirement benefits charge includes £313m (2021: £289m; 2020: £279m) in respect of defined contribution schemes and £250m (2021: £250m; 2020: £240m) in respect of defined benefit schemes. b £604m (2021: £484m; 2020: £451m) of Group compensation was capitalised as internally generated software and excluded from the Staff cost disclosed above .

Disclosure of terms and conditions of share-based payment arrangement [abstract]
Share-based payments	Share-based payments Accounting for share-based payments The Group applies IFRS 2 Share-based Payments in accounting for employee remuneration in the form of shares. 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. 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 2022 2021 2020 £m £m £m Deferred Share Value Plan and Share Value Plan 295 256 245 Others 214 216 184 Total equity settled 509 472 429 Cash settled 4 5 2 Total share-based payments 513 477 431 The terms of the main current plans are as follows: Share Value Plan (SVP) The SVP was introduced in Barclays PLC Group in March 2010. 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 DSVP was introduced in February 2017. 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: 2022 2021 Weighted average fair value per award granted in year Weighted average share price at exercise/release during year Weighted Number of Weighted average fair value per award granted in year Weighted average share price at exercise/release during year Weighted Number of £ £ in years (000s) £ £ in years (000s) DSVP and SVP a,b 1.43 1.61 1 501,454 1.62 1.76 1 413,859 Others a 0.38-1.64 1.59-1.66 0-3 316,534 0.64-1.8 1.75-1.92 0-3 335,976 Notes a Options/award granted over Barclays PLC shares. b Weighted average exercise price is not applicable for SVP and DSVP awards as these are not share option schemes. 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 31.10% for 3 years and 30.56% for 5 years. The risk free interest rates used for valuations are 4.28% and 4.05% for 3 years and 5 years respectively. The pure dividend yield rates used for valuations are 4.01% and 3.93% for 3 years and 5 years respectively. The repo rates used for valuations are (0.47)% and (0.63)% 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 the market data. Movements in options and awards The movement in the number of options and awards for the major schemes and the weighted average exercise price of options was: DSVP and SVP a,b Others a,c Number (000s) Number (000s) Weighted average ex. price (£) 2022 2021 2022 2021 2022 2021 Outstanding at beginning of year/acquisition date 413,859 416,941 335,976 356,033 0.95 0.96 Granted in the year 291,876 187,667 146,203 120,385 1.33 1.43 Exercised/released in the year (178,634) (160,460) (133,682) (107,688) 1.15 1.38 Less: forfeited in the year (25,647) (30,289) (28,789) (24,489) 1.01 0.95 Less: expired in the year — — (3,174) (8,265) 1.23 1.67 Outstanding at end of year 501,454 413,859 316,534 335,976 0.97 0.95 Of which exercisable: — — 34,247 28,609 1.19 1.23 Notes a Options/award granted over Barclays PLC shares. b Weighted average exercise price is not applicable for SVP and DSVP awards as these are not share option schemes. c The number of awards within Others at the end of the year principally relates to Sharesave (number of awards exercisable at end of year was 13,954,749). The weighted average exercise price relates to Sharesave. Awards and options granted under the Group’s share plans may be satisfied using new issue shares, treasury shares and market purchase shares. Awards granted under the DSVP may be satisfied using market purchase shares only. There were no significant modifications to the share-based payments arrangements in 2022 and 2021. As at 31 December 2022, the total liability arising from cash-settled share-based payments transactions was £5m (2021: £5m). Holdings of Barclays PLC shares and hedges Various employee benefit trusts established by the Group hold shares in Barclays PLC to meet obligations under the Barclays share-based payment schemes. The total number of Barclays shares held in these employee benefit trusts at 31 December 2022 was 14m (2021: 12.9m). Dividend rights have been waived on all these shares. The total market value of the shares held in trust based on the year end share price of £1.59 (2021: £1.87) was £22m (2021: £24m). For accounting of treasury shares, see Note 29. The Group has entered into physically settled forward contracts to hedge the settlement of certain share-based payment schemes. The fixed forward price to be paid under these contracts is £469m and has been recorded in retained earnings.

Disclosure of defined benefit plans [abstract]
Pension and post-retirement benefits	Pensions and post-retirement benefits Accounting for pensions and post-retirement benefits The Group operates a number of pension schemes and post-employment benefit schemes. Defined contribution schemes – the 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 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 Group, using a methodology similar to that for defined benefit pension schemes. Pension schemes UK Retirement Fund (UKRF) The UKRF is the Group’s main scheme, representing 96% (2021: 97%) of the 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 Barclays 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 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 Barclays 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 Barclays 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, Barclays 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 Group. The Trustee Board comprises six Management Directors selected by Barclays, of whom three are independent Directors with no relationship with Barclays (and who are not members of the UKRF), plus three Member Nominated Directors selected from eligible active members of the UKRF, deferred and 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 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 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 31 Staff costs.

As at 31 December 2022, the UKRF’s scheme assets were in surplus versus IAS 19 obligations by £4,690m (2021: £3,819m). The increase in the UKRF surplus during the year was driven by £294m of deficit reduction contributions and the unwind of the Senior Notes (see later in note), partially offset by higher than expected inflation experienced during the year. The UKRF assets and benefit obligation have reduced by c£10bn and c£11bn respectively over the year, primarily due to higher gilt and bond yields. This is as expected from the investment strategy which aims to invest in assets that move in value in line with changes in liability values. The weighted average duration of the benefit payments reflected in the defined benefit obligation for the UKRF is 13 years (2021: 16 years) . The decrease in duration is primarily due to the increase in discount rate, driven by higher corporate bond yields. The UKRF expected benefits are projected to be paid out for in excess of 50 years, although 30% of the total benefits are expected to be paid in the next 10 years; 30% in years 11 to 20 and 25% in years 21 to 30. The remainder of the benefits are expected to be paid beyond 30 years. Of the £1,299m (2021: £1,268m) UKRF benefits paid out, £390m (2021: £419m) 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 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 the Group or termination of contributions by the Group. 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. 2022 2021 Key UKRF financial assumptions % p.a. % p.a. Discount rate 4.80 1.84 Inflation rate (RPI) 3.21 3.56 The UKRF discount rate assumption for 2022 was based on a standard WTW RATE Link model. The RPI inflation assumption for 2022 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 an updated best estimate assumption 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 2021 core projection model published by the Continuous Mortality Investigation Bureau subject to a long-term trend of 1.25% per annum in future improvements (2021: 1.5% per annum). An additional allowance has been made within the mortality assumptions to reflect the uncertain impact of COVID-19 in the long term. The table below shows how the assumed life expectancy at 60, for members of the UKRF, has varied over the past three years: Assumed life expectancy 2022 2021 2020 Life expectancy at 60 for current pensioners (years) – Males 26.8 27.3 27.2 – Females 29.5 29.6 29.4 Life expectancy at 60 for future pensioners currently aged 40 (years) – Males 28.3 29.1 29.0 – Females 31.0 31.4 31.2 The UKRF entered into a longevity reinsurance contract in 2022 covering £7bn of the pensioner liabilities. This is in addition to a £5bn transaction executed in 2020. In total, over three-quarters of the longevity risk for current pensioners has been reinsured, and the transactions will provide income to the UKRF in the event that pensions are paid out for longer than expected. The contracts form part of the UKRF’s investment portfolio. At 31 December 2022, the contracts are valued at £(123)m (2021: nil). The negative value placed on the longevity reinsurance contracts at 31 December 2022 reflects the estimated impact of changes in the reinsurance market, demographic assumptions and risk premia since the 2020 transaction was entered into by the UKRF. The 2022 transaction is valued at nil as it is assessed to have been transacted recently at fair value. 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 Barclays expressing any specific view of the probability of such movements happening.

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.

Valuations of complex instruments are based on UKRF custodian valuations. The valuation for some of the unquoted assets, in particular Private equities, is based on valuations as at 30 September 2022 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. b Cash and liquid assets for the UKRF consists of £521m (2021: £488m) Cash, £80m (2021: £93m) Receivables/payables, £3,286m (2021:£2,275m) Pooled cash funds and £(2,390)m (2021: £(2,459)m) Repurchase agreements. c The asset allocation for 2021 has been re-presented to reflect the re-interpretation of the asset classifications as well as a reclassification of £1.2bn between unquoted/quoted bonds, in a manner that management believes better represents the underlying nature of the assets. Included within the fair value of UKRF scheme assets was nil (2021: nil) relating to shares in Barclays PLC and nil (2021: nil) relating to bonds issued by Barclays PLC. The UKRF also invests in pooled investment vehicles which may hold shares or debt issued by Barclays PLC. There has been no significant change in the UKRF investment strategy over the year, however, given the movement in the gilt and bond yields over the year, the relative weights of assets classes have changed. No additional support from the Group was required in response to the market volatility experienced over the year. The UKRF assets as at 31 December 2021 do not include the Senior Notes referred to in the section below on Triennial Valuation, as these were non-transferable instruments and not recognised under IAS 19. The Senior Notes were redeemed in December 2022, and the redemption proceeds are now included in Cash and Liquid Assets as at 31 December 2022. Approximately 34% of the UKRF assets are 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. 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 latest triennial actuarial valuation of the UKRF showed a funding surplus of £2.0bn at 30 September 2022 (2021 update: £0.6bn surplus). The improvement was mainly due to £294m of deficit reduction contributions, changes to views on life expectancy and inflationary returns on assets relative to liabilities being better than expected. The main differences between the funding and accounting assumptions are a different approach to setting the discount rate and a more conservative longevity assumption for funding. As the UKRF has a funding surplus, the 2023 deficit reduction contribution (£286m), agreed as part of the 2019 triennial actuarial valuation, is no longer required, and a new recovery plan was not required. 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 next funding valuation of the UKRF is due to be completed in 2026 with an effective date of 30 September 2025. Subscription for Fixed rate notes During 2019 and 2020 the UKRF subscribed for non-transferable listed senior fixed rate notes for £1,250m, backed by UK gilts (the Senior Notes). These investments were partially financed by £1,000m deficit reduction contributions. The Senior Notes were issued by two entities consolidated in the Barclays Bank Group under IFRS 10: Heron Issuer Limited (Heron) for £500m and Heron Issuer Number 2 Limited (Heron 2) for £750m. The Senior Notes entitled the UKRF to semi-annual coupon payments for five years, and full repayment in cash in three tranches: £250m in 2023, £750m in 2024 and £250m at final maturity in 2025. Heron and Heron 2 acquired a total of £1,500m of gilts from Barclays Bank PLC for cash to support payments on the Senior Notes. Barclays Bank PLC subscribed for the junior notes issued by Heron and Heron 2 for £250m. The regulatory capital impact, which otherwise would have occurred in 2019 and 2020 from the regular deficit reduction contributions, would have been deferred until 2023, 2024 and 2025 upon maturity of the Senior Notes. As part of the planned early unwind of these transactions disclosed in Barclays PLC’s Q1 2022 Results Announcement, Barclays Bank PLC purchased the Senior Notes at fair value from the UKRF for cash in December 2022. The UKRF’s investment in the Senior Notes did not qualify as a plan asset under IAS 19; so the purchase of the Senior Notes for cash increased IAS 19 plan assets by £1,250m and thereby accelerated the regulatory capital impact of the deficit reduction contributions to 2022 from 2023, 2024 and 2025. Barclays Bank PLC subsequently reacquired the gilts held by Heron and Heron 2 in exchange for the redemption of all the fixed rate notes. The gilts were disposed of by Barclays Bank PLC prior to year end. 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 £9bn, to provide security for the UKRF funding deficit as it increases or decreases over time. 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 a 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 2016, Barclays Bank UK PLC is a participating employer in the UKRF and will remain so during a transitional phase until September 2025 as set out in a deed of participation. Barclays Bank UK PLC will make contributions for the future service of its employees who are currently Afterwork members and, 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 the collateral above). Defined benefit contributions paid with respect to the UKRF were as follows: Contributions paid £m 2022 1,785 2021 955 2020 748 There were nil (2021: nil) Section 75 contributions included within the Group’s contributions paid as no participating employers left the UKRF in 2022. The Group’s expected contribution to the UKRF in respect of defined benefits in 2023 is £38m (2022: £546m). In addition, the expected contributions to UK defined contribution schemes in 2023 is £32m (2022: £33m) to the UKRF and £243m (2022: £221m) to the BPSP.

Principal subsidiaries

Disclosure of subsidiaries [abstract]
Principal subsidiaries	Principal subsidiaries The Group applies IFRS 10 Consolidated Financial Statements. The consolidated financial statements combine the financial statements of the Group and all its subsidiaries. Subsidiaries are entities over which the Group has control. Under IFRS 10, this is when the Group is exposed or has rights to variable returns from its involvement in the entity and has the ability to affect those returns through its power over the entity. The Group reassesses whether it controls an entity if facts and circumstances indicate that there have been changes to its power, its rights to variable returns or its ability to use its power to affect the amount of its returns. Intra-group transactions and balances are eliminated on consolidation and consistent accounting policies are used throughout the Group for the purposes of the consolidation. Changes in ownership interests in subsidiaries are accounted for as equity transactions if they occur after control has been obtained and they do not result in loss of control. The significant judgements used in applying this policy are set out below. Accounting for investment in subsidiaries In the individual financial statements of Barclays PLC, investments in subsidiaries are stated at cost less impairment. Principal subsidiaries for the Group are set out below. This includes those subsidiaries that are most significant in the context of the Group’s business, results or financial position. Principal place of business or incorporation Percentage of voting rights held Non-controlling interests - proportion of ownership interests Non-controlling interests - proportion of voting interests Company name Nature of business % % % Barclays Bank PLC United Kingdom Banking, holding company 100 2 — Barclays Bank UK PLC United Kingdom Banking, holding company 100 — — Barclays Bank Ireland PLC Ireland Banking 100 — — Barclays Execution Services Limited United Kingdom Service company 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. Refer to Note 30 for more information. Determining whether the 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 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 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 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 Group has control of an entity. However, the entity set out below is excluded from consolidation because the Group does not have exposure to its variable returns. Percentage of voting rights held Equity shareholders' funds Retained profit for the year Company name Country of registration or incorporation % £m £m Palomino Limited Cayman Islands 100 — — This entity is managed by an external counterparty and consequently is not controlled by the Group. Interests relating to this entity are included in Note 35. Significant restrictions As is typical for a group of its size and international scope, there are restrictions on the ability of Barclays PLC to obtain distributions of capital, access the assets or repay the liabilities of members of its 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 Barclays’ principal subsidiary companies have assets and liabilities before intercompany eliminations of £1,962bn (2021: £1,833bn) and £1,869bn (2021: £1,737bn) respectively. Certain of these assets and liabilities are subject to prudential regulation and regulatory capital requirements in the countries in which they are regulated. These require entities to maintain minimum capital levels which cannot be returned to the parent company, Barclays PLC, on a going concern basis. In order to meet capital requirements, subsidiaries may issue certain equity-accounted and debt-accounted financial instruments and non-equity instruments such as Tier 1 and Tier 2 capital instruments and other forms of subordinated liabilities. Refer to Note 27 and Note 28 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 Group are required to meet applicable PRA or local regulatory requirements pertaining to liquidity. Some of the regulated subsidiaries include Barclays Bank PLC and Barclays Capital Securities Limited (which are regulated on a combined basis under a Domestic Liquidity Sub-Group (DoLSub) arrangement), Barclays Bank UK PLC, Barclays Bank Ireland PLC, Barclays Capital Inc. and Barclays Bank Delaware. Refer to the Liquidity risk section for further details of liquidity requirements, including those of the Group’s significant subsidiaries. Statutory requirements The 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 PLC, the ultimate 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 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 Group. The assets typically affected are disclosed in Note 38. Other restrictions The Group is required to maintain balances with central banks and other regulatory authorities, and these amounted to £3,457m (2021: £4,750m).

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. 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 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 Group has contractual arrangements which may require it to provide financial support to the following types of consolidated structured entities: • Securitisation vehicles: The Group uses securitisation as a source of financing and a means of risk transfer. Where entities are controlled by the Group, they are consolidated. Refer to Note 37 for further detail. ▪ Commercial Paper (CP) conduits: These entities issue CP and use the proceeds to lend to clients as part of the Group's multi-seller conduit programme. The Group has provided £20.8bn (2021: £17.2bn) in contractual liquidity facilities to the CP conduits that the 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. ▪ Employee benefit trusts: The Group provides capital contributions to employee benefit trusts to enable them to meet obligations to employees in relation to share-based remuneration arrangements. ▪ Tender Option Bond (TOB) trusts: During 2022, the Group provided undrawn liquidity facilities of £3.8bn (2021: £3.3bn) 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 The term ‘unconsolidated structured entities’ refers to structured entities not controlled by Barclays, and are established either by Barclays 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 Group. Such interests include holdings of debt or equity securities, derivatives that transfer financial risks from the entity to the Group, lending, loan commitments, financial guarantees and investment management agreements. The 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 CIB business. Structured entities may take the form of funds, trusts, securitisation vehicles, and private investment companies. The largest transactions for Barclays 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 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 2022 Assets Trading portfolio assets — 8,632 — — 8,632 Financial assets at fair value through the income statement 75,166 — — 2,459 77,625 Derivative financial instruments — — 4,555 — 4,555 Financial assets at fair value through other comprehensive income — — — 423 423 Loans and advances at amortised cost — — — 44,292 44,292 Reverse repurchase agreements and other similar secured lending 117 — — — 117 Other assets — — — 69 69 Total assets 75,283 8,632 4,555 47,243 135,713 Liabilities — Derivative financial instruments — — 8,460 — 8,460 As at 31 December 2021 Assets Trading portfolio assets — 7,170 — — 7,170 Financial assets at fair value through the income statement 61,816 — — 3,490 65,306 Derivative financial instruments — — 5,160 — 5,160 Financial assets at fair value through other comprehensive income — — — 91 91 Loans and advances at amortised cost — — — 28,227 28,227 Reverse repurchase agreements and other similar secured lending 104 — — — 104 Other assets — — — 17 17 Total assets 61,920 7,170 5,160 31,825 106,075 Liabilities Derivative financial instruments — — 9,543 — 9,543 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 2022, there were 6,267 (2021: 5,891) structured entities that Barclays entered into transactions with. Secured financing The 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 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 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 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 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 which 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 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 14. 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 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 Group is mainly exposed to settlement risk on these derivatives which is mitigated through daily margining. Total notional contract amounts were £244,780m (2021: £217,055m). 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 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 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.

Maximum exposure to loss Unless specified otherwise below, the 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 Barclays' 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 entities. The 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 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 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 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 period the Group incurred an impairment of £32m (2021: £28m) 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 performance of the fund and trusts held on behalf of beneficiaries with interests restricted to unpaid fees. Assets transferred to sponsored unconsolidated structured entities Barclays 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 2022, assets transferred to sponsored unconsolidated structured entities were £1,665m (2021: £1,662m).

Investments in associates and joint ventures	Investments in associates and joint ventures Accounting for associates and joint ventures The Group applies IAS 28 Investments in Associates and IFRS 11 Joint Arrangements. Associates are entities in which the Group has significant influence, but not control, over the operating and financial policies. Generally the Group holds more than 20% but less than 50% of their voting shares. Joint ventures are arrangements where the Group has joint control and rights to the net assets of the entity. The Group’s investments in associates and joint ventures are initially recorded at cost and increased (or decreased) each year by the Group’s share of the post acquisition profit/(loss). The Group ceases to recognise its share of the losses of equity accounted associates when its share of the net assets and amounts due from the entity have been written off in full, unless it has a contractual or constructive obligation to make good its share of the losses. In some cases, investments in these entities may be held at fair value through profit or loss, for example, those held by private equity businesses. The equity accounted associates include the Group's investment in the Business Growth Fund £669m (2021: £699m) which has increased due to a fair value gain in its investments by £(21)m (2021: £220m). 2022 2021 Associates Joint ventures Total Associates Joint ventures Total £m £m £m £m £m £m Equity accounted 695 227 922 722 277 999 Held at fair value through profit or loss — 435 435 — 444 444 Total 695 662 1,357 722 721 1,443 Summarised financial information for the Group’s equity accounted associates and joint ventures is set out below.

Securitisations

Disclosure of transferred financial assets that are not derecognised in their entirety [abstract]
Securitisations	Securitisations Accounting for securitisations The 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 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 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 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 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 Group was party to securitisation transactions involving its credit card balances and other personal lending. 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 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: 2022 2021 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 Loans and advances at amortised cost Credit cards, unsecured and other retail lending 5,324 5,761 (1,537) (1,460) 1,262 1,382 (1,225) (1,219) Mortgage Loans 496 439 (20) (20) 0 0 0 0 Financial assets at FVTPL Mortgage Loans 330 330 0 0 41 41 0 0 Total 6,150 6,530 (1,557) (1,480) 1,303 1,423 (1,225) (1,219) Balances included within loans and advances at amortised cost represent securitisations where substantially all the risks and rewards of the asset have been retained by the Group and balances included within Financial assets at FVTPL 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 Barclays 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 is recognised to the extent of Barclays’ continuing involvement. In 2022, financial assets of £828m (2021: £249m) were transferred in this manner and the carrying value of the asset representing continued involvement is included in the table above. For transfers of assets in relation to repurchase agreements, refer to Note 38. Continuing involvement in financial assets that have been derecognised In some cases, the 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 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 a Gain from continuing involvement Carrying amount Fair value Maximum exposure to loss For the year ended Cumulative to 31 December Type of transfer £m £m £m £m £m 2022 Asset backed securities 8 8 8 1 3 Residential mortgage backed securities 913 907 913 18 22 Commercial mortgage backed securities 412 357 412 5 16 Total 1,333 1,272 1,333 24 41 2021 Asset backed securities 25 25 25 1 2 Residential mortgage backed securities 574 574 574 3 4 Commercial mortgage backed securities 311 307 311 5 11 Total 910 906 910 9 17 Note a Assets which represent the Group’s continuing involvement in derecognised assets are recorded in Loans and advances at amortised cost and Debt securities at FVTPL.

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 Group balance sheet, for example because Barclays retains substantially all the exposure to those assets under an agreement to repurchase them in the future for a fixed price. Assets pledged or transferred as collateral include all assets categorised as encumbered in the disclosure on pages 180 to 182 of the Barclays PLC Pillar 3 Report 2022 (unaudited), other than those held in commercial paper conduits. In these transactions, the Group will be required to step in to provide financing itself under a liquidity facility if the vehicle cannot access the commercial paper market. 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 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. The following table summarises the nature and carrying amount of the assets pledged as security against these liabilities: 2022 2021 £m £m Cash collateral and settlements 78,996 66,138 Loans and advances at amortised cost 64,772 65,216 Trading portfolio assets 63,969 71,518 Financial assets at fair value through the income statement 8,220 5,595 Financial assets at fair value through other comprehensive income 18,210 13,748 Assets pledged 234,167 222,215 The following table summarises the transferred financial assets and the associated liabilities. The transferred assets represent the gross carrying value of the assets pledged and the associated liabilities represent the IFRS balance sheet value of the related liability recorded on the balance sheet: Transferred assets Associated liabilities £m £m At 31 December 2022 Derivatives 79,474 (79,474) Repurchase agreements 74,291 (46,617) Securities lending arrangements 67,554 — Other 12,848 (11,055) 234,167 (137,146) At 31 December 2021 Derivatives 66,744 (66,744) Repurchase agreements 71,820 (49,543) Securities lending arrangements 69,316 — Other 14,335 (12,121) 222,215 (128,408) For repurchase agreements the difference between transferred assets and the associated liabilities is predominantly due to IFRS netting. Included within Other are agreements where a counterparty's recourse is limited to the transferred assets.

As a result, the UK’s Financial Conduct Authority (FCA) and other global regulators instructed market participants to prepare for the cessation of most LIBOR rates after the end of 2021, and to adopt “Risk-Free Rates” (RFRs). Pursuant to FCA announcements during 2021, panel bank submissions for all GBP, JPY, EUR and CHF LIBOR tenors ceased after 31 December 2021. For USD, certain actively used tenors will continue to be provided until end June 2023 in their current form, however in line with the US banking regulators’ joint statement, Barclays ceased issuing or entering into new contracts that use USD LIBOR as a reference rate from 31 December 2021, other than in relation to those allowable use cases set out under the FCA's prohibition notice (ref 21A). These include, amongst others, market making in support of client activity; or transactions that reduce or hedge Barclays' or any client of Barclays' USD LIBOR exposure on contracts entered into before 1 January 2022. The Group’s exposure to rates subject to benchmark interest rate reform has been predominantly to GBP, USD, JPY and CHF LIBOR and Euro Overnight Index Average (EONIA) in addition to GBP LIBOR ICE Swap Rate, JPY LIBOR Tokyo Swap Rate and USD LIBOR ICE Swap Rate, with the vast majority concentrated in derivatives within the Investment Bank. Some additional exposure exists on floating rate loans and advances, repurchase and securities lending agreements and debt securities held and issued within the Corporate and Investment Bank. Following transition activity in late 2021 and early 2022, almost all GBP LIBOR, GBP LIBOR ICE Swap Rate, JPY LIBOR and JPY LIBOR Tokyo Swap Rate and CHF LIBOR and EONIA positions (“2021 scope”) have transitioned onto RFRs and while there are a number of benchmarks yet to cease, the Group’s risk exposure is now mainly to USD LIBOR and the USD LIBOR ICE Swap Rate. There are key differences between IBORs and RFRs. IBORs are ‘term rates’, which means that they are published for a borrowing period (for example three months) and they are ‘forward-looking’, because they are published at the beginning of a borrowing period, based upon an estimated inter-bank borrowing cost for the period. RFRs are based upon overnight rates from actual transactions and are therefore published after the end of the overnight borrowing period. Furthermore, IBORs include term and credit risk premiums. Therefore, to transition existing contracts and agreements to RFRs, adjustments for term and credit differences may need to be applied to RFR-linked rates. The methodologies for these adjustments have been determined through in-depth consultations by industry working groups, on behalf of the respective global regulators and related market participants. How the Group is managing the transition to alternative benchmark rates Barclays has established a Group-wide LIBOR Transition Programme. The Transition Programme spans all business lines and has cross-functional governance which includes Legal, Compliance, Conduct Risk, Risk and Finance. The Transition Programme aims to drive strategic execution and identify, manage and resolve key risks and issues as they arise. Barclays continues to provide quarterly updates on progress and exposures to the PRA/FCA and other regulators as required. The Transition Programme follows a risk-based approach, using recognised ‘change delivery’ control standards. Accountable Executives are in place within key working groups and workstreams, with overall Board oversight delegated to the Board Risk Committee. Approaches to USD LIBOR and USD LIBOR ICE Swap Rate exposure transition vary by product and nature of counterparty. The Group has engaged with counterparties to transition or include robust fallback provisions where not already agreed in contracts with maturities after June 2023, when USD LIBOR and the USD LIBOR ICE Swap Rate will either cease to be published or cease to be published, in its current form. Any fallback provision will provide the relevant replacement rate, in the case of the ISDA 2020 IBOR Fallbacks Protocol this is the RFR plus a credit adjustment spread. For bilateral derivative exposure, adherence to the relevant ISDA Fallback Protocols have provided Barclays with an efficient mechanism to amend outstanding trades to incorporate fallbacks. Beyond the ISDA 2020 IBOR Fallbacks Protocol and the ISDA 2021 Fallbacks Protocol, another option has been to bilaterally amend terms with counterparties. Derivative contracts facing central clearing counterparties (CCP) will follow a market-wide, standardised approach to reform through a series of CCP-led conversions, similar to those used for GBP, JPY and CHF LIBOR and EONIA. GBP and JPY LIBOR ceased to be published in their original form from the end of 2021 and synthetic versions of GBP and JPY LIBOR have been made available for a limited period of time. This was to help mitigate the risk of widespread disruption to legacy LIBOR contracts which had not transitioned by end 2021, when the GBP and JPY panel bank submissions ended. The FCA has reiterated that any synthetic LIBOR tenors are only a bridge to give time to transition to appropriate alternative RFRs and not a permanent solution. Barclays continues to monitor, assess and limit the reliance on synthetic LIBOR. On 29th September 2022 the FCA announced that the 1- and 6- month synthetic GBP LIBOR tenors would cease immediately after 31st March 2023 and confirmed that the synthetic JPY LIBOR tenors would cease permanently at end 2022. On 23rd November 2022 the FCA announced that the 3-month synthetic GBP LIBOR tenor will cease at end March 2024 and that the overnight and 12-month USD LIBOR tenors will cease at end June 2023. The FCA also proposed that the 1-, 3- and 6-month USD LIBOR tenors should be published under a synthetic methodology for a temporary period until end September 2024. A final decision from the FCA is expected by early in the second quarter of 2023. US Federal legislation (the Adjustable Interest Rate (LIBOR) Act) has been enacted which provides a solution for contracts governed under US law which reference USD LIBOR but do not have adequate fallbacks. The effect of this legislation on in scope agreements will be to deem all references to USD LIBOR to the replacement Secured Overnight Financing Rate (SOFR) with the additional benefit of statutory contract continuity and safe harbour protection. This contrasts with the legislation implemented in the UK which provides for statutory contract continuity with safe harbour protection only for the administrator and could expose market participants to additional litigation risk. Progress made during 2022 During 2022, Barclays delivered technology and business process changes required to ensure operational readiness in preparation for transitions to RFRs for those benchmark rates ceasing June 2023, this included new RFR product capabilities and alternatives to LIBOR across loans, bonds, repurchase and securities lending transactions and derivatives. Barclays continued to monitor and address its unremediated exposure to 2021 scope; noting that this exposure, excluding secondary traded loans and bonds, was reduced to £2bn gross notional as at 31 December 2022, which accounts for less than 0.2% of baseline exposure for 2021 scope. Of this, £1.2bn relates to undrawn lending facilities with £1.1bn of this made up of syndicated loans where transition is led by a third-party agent. The remaining £0.8bn is predominantly made up of bilateral derivatives without appropriate fallbacks. Work is ongoing with clients and agents, as appropriate, to address the outstanding unremediated exposures. Barclays is now focused on transition of legacy positions related to USD LIBOR and USD LIBOR ICE Swap Rate (and other in-scope IBORs) and remains on track to meet the associated industry deadlines. In the first half of 2022, Barclays successfully transitioned all uncommitted lending exposures. Risks to which the Group is exposed as a result of the transition Global regulators and central banks in the UK, US, EU and APAC have been driving international efforts to reform key benchmark interest rates and indices, such as LIBOR, which are used to determine the amounts payable under a wide range of transactions and make them more reliable and robust. These benchmark reforms have resulted in significant changes to the methodology and operation of certain benchmarks and indices, the adoption of RFRs, the discontinuation of certain reference rates (including LIBOR), and the introduction of implementing legislation and regulations. Notwithstanding these developments, given the unpredictable consequences of benchmark reform, any of these developments could have an adverse impact on market participants, including the Group, in respect of any financial instruments linked to, or referencing, any of these benchmark interest rates. Uncertainty associated with such potential changes include: • the availability and/or suitability of alternative RFRs, • the participation of customers and third-party market participants in the transition process • challenges with respect to required documentation changes; and • impact of legislation to deal with ‘certain legacy’ contracts that cannot convert into RFRs or add RFR fallbacks before cessation of the benchmark they reference. This uncertainty may adversely affect a broad range of transactions (including any securities, loans, repurchase and securities lending transactions and derivatives which use LIBOR or any other affected benchmark to determine the amount of interest payable that are included in the Group’s financial assets and liabilities) that use these reference rates and indices, and present a number of risks for the Group, including, but not limited to: ▪ Conduct risk: in undertaking actions to transition away from using certain reference rates (such as LIBOR) to new alternative RFRs, the Group faces conduct risks. These may lead to customer complaints, regulatory sanctions or reputational impact if the Group is considered to be (among other things): (i) undertaking market activities that are manipulative or create a false or misleading impression, (ii) misusing sensitive information or not identifying or appropriately managing or mitigating conflicts of interest, (iii) providing customers with inadequate advice, misleading information, unsuitable products or unacceptable service, (iv) not taking a consistent approach to remediation for customers in similar circumstances, (v) unduly delaying the communication and migration activities in relation to client exposure, leaving them insufficient time to prepare, or (vi) colluding or inappropriately sharing information with competitors. ▪ Litigation risk: members of the Group may face legal proceedings, regulatory investigations and/or other actions or proceedings regarding (among other things): (i) the conduct risks identified above, (ii) the interpretation and enforceability of provisions in LIBOR-based contracts, and (iii) the Group’s preparation and readiness for the replacement of LIBOR with alternative RFRs. ▪ Financial risk: the valuation of certain of the Group’s financial assets and liabilities may change. Moreover, transitioning to alternative RFRs may impact the ability of members of the Group to calculate and model amounts receivable by them on certain financial assets and determine the amounts payable on certain financial liabilities (such as debt securities issued by them) because certain alternative RFRs (such as SONIA and the SOFR) are look-back rates whereas term rates (such as LIBOR) allow borrowers to calculate at the start of any interest period exactly how much is payable at the end of such interest period. This may have a material adverse effect on the Group’s cash flows. ▪ Pricing risk: changes to existing reference rates and indices, discontinuation of any reference rate or indices and transition to alternative RFRs may impact the pricing mechanisms used by the Group on certain transactions. ▪ Operational risk: changes to existing reference rates and indices, discontinuation of any reference rate or index and transition to alternative RFRs may require changes to the Group’s IT systems, trade reporting infrastructure, operational processes, and controls. In addition, if any reference rate or index (such as LIBOR) is no longer available to calculate amounts payable, the Group may incur additional expenses in amending documentation for new and existing transactions and/or effecting the transition from the original reference rate or index to a new reference rate or index. ▪ Accounting risk: an inability to apply hedge accounting in accordance with IAS 39 could lead to increased volatility in the Group’s financial results and performance. Any of these factors may have a material adverse effect on the Group’s business, results of operations, financial condition, prospects, and reputation. While a number of the above risks in relation to transition of legacy 2021 scope onto RFRs have been substantially mitigated, they remain relevant in relation to USD LIBOR transitions. The Group does not expect material changes to its risk management approach and strategy as a result of interest rate benchmark reform. The following tables summarise USD LIBOR and USD LIBOR ICE Swap Rate non-derivatives exposures due to mature post 30 June 2023, when USD LIBOR and the USD LIBOR ICE Swap Rate will either cease to be published or cease to be published, in its current form: USD LIBOR 2022 2021 As at 31 December £m £m Non-derivative financial assets Loans and advances at amortised cost 8,659 15,812 Reverse repurchase agreements and other similar secured lending — 186 Financial assets at fair value through the income statement 4,282 8,538 Financial assets at fair value through other comprehensive income — — Non-derivative financial assets 12,941 24,536 Non-derivative financial liabilities Debt securities in issue (9,062) (6,137) Subordinated liabilities (1,132) (1,088) Financial liabilities designated at fair value (1,740) (212) Non-derivative financial liabilities (11,934) (7,437) Equity Other equity instruments (1,786) (3,374) Standby facilities, credit lines and other commitments a 68,118 42,767 Note a For year ended 2021, multi currency loan facilities are reported in the currency which needs to be remediated first, which were mainly non-USD. As the non-USD rates transitioned, this has resulted in a corresponding increase in USD LIBOR exposure for year ended 2022 as USD LIBOR exposure is yet to transition. Balances reported at amortised cost are disclosed at their gross carrying value and do not include any expected credit losses that may be held against them. The following tables summarise USD LIBOR and USD LIBOR ICE Swap Rate derivative exposures due to mature post 30 June 2023: USD LIBOR 2022 2021 £m £m Derivative notional contract amount OTC interest rate derivatives 2,594,268 2,283,236 OTC interest rate derivatives - cleared by central counterparty 2,137,245 2,228,399 Exchange traded interest rate derivatives 337,535 466,339 OTC foreign exchange derivatives 84 461,680 OTC equity and stock index derivatives 1,261 9,949 Derivative notional contract amount 5,070,393 5,449,603 Derivatives are reported using the notional contract amount As at 31 December 2022 the Group also had £9bn (2021: £9bn) of Barclays issued debt retained by the group, impacted by the interest rate benchmark reform, in USD LIBOR. Fallback clauses The USD LIBOR and USD LIBOR ICE Swap Rate as at 31 December 2022 exposure has been broken up into those with robust fallbacks and those without. Fallbacks here are defined as any mechanism involving a ‘switch’ or ‘hardwire’ or a contractual agreement to automatically transition to an agreed rate. One of the most commonly used market solutions to incorporate fallback provisions into certain legacy non-cleared derivative agreements are the ISDA Fallbacks Protocols, namely the ISDA 2020 IBOR Fallbacks Protocol and the ISDA 2021 Fallbacks Protocol published in October 2020. Market participants who have adhered to the relevant ISDA Fallbacks Protocol agree, between adhering parties, that their legacy non-cleared contracts will be amended to include the relevant fallback provisions. The following table presents a breakdown of USD LIBOR and USD LIBOR ICE Swap Rate non-derivative exposures with robust fallbacks in place and those without as at 31 December 2022: USD LIBOR With robust fallback clause Without robust fallback clause As at 31 December 2022 £m £m Non-derivative financial assets Loans and advances at amortised cost 7,770 889 Financial assets at fair value through the income statement 4,282 — Non-derivative financial assets 12,052 889 Non-derivative financial liabilities Debt securities in issue (9,062) — Subordinated liabilities (1,132) — Financial liabilities designated at fair value (1,740) — Non-derivative financial liabilities (11,934) — Equity Other equity instruments (1,786) — Standby facilities, credit lines and other commitments 64,632 3,486 The following table presents a breakdown of USD LIBOR and USD LIBOR ICE Swap Rate derivative exposures with robust fallbacks in place and those without as at 31 December 2022: USD LIBOR With robust fallback clause Without robust fallback clause As at 31 December 2022 £m £m Derivative notional contract amount OTC interest rate derivatives 2,538,218 56,050 OTC interest rate derivatives - cleared by central counterparty 2,137,245 — Exchange traded interest rate derivatives 337,535 — OTC foreign exchange derivatives 84 — OTC equity and stock index derivatives 770 491 Derivative notional contract amount 5,013,852 56,541 The majority of USD LIBOR and USD LIBOR ICE Swap Rate exposures are already covered by fallbacks as a result of the 2020 ISDA IBOR Fallbacks Protocol and the June 2022 Benchmark Module of the ISDA 2021 Fallbacks Protocol which relevant Barclays entities have adhered to.

Condensed Financial Information Disclosure [Abstract]
Barclays PLC (the Parent company)	Barclays PLC (the Parent company) Total income Dividends received from subsidiaries Dividends received from subsidiaries of £2,797m (2021: £1,356m, 2020: £763m) relates to dividends received from Barclays Execution Services Limited £1,080m, Barclays Bank UK PLC £1,010m, Barclays Principal Investments Limited £507m and Barclays Bank PLC £200m. The dividends received in 2020 from its banking subsidiaries were paid up to Barclays PLC prior to the announcement made by the PRA on 31 March 2020 that capital be preserved for use in serving Barclays customers and clients through the extraordinary challenges presented by the COVID-19 pandemic. As part of a response to this announcement, Barclays PLC took steps to provide additional capital to its banking subsidiaries. Other expenses Other expenses of £654m (2021: £659m income, 2020: £1,192m income) includes fair value and foreign exchange losses of £1,673m (2021: £250m, 2020: £248m) on positions with subsidiaries partially offset by £905m (2021: £804m, 2020: £857m) of income received from gross coupon payments on Barclays Bank PLC and Barclays Bank UK PLC-issued AT1 securities. Total assets and liabilities Investment in subsidiaries The investment in subsidiaries of £64,544m (2021: £62,528m) predominantly relates to investments in the ordinary shares of Barclays Bank PLC of £36,340m (2021: £35,590m) and their AT1 securities of £10,760m (2021: £9,493m), as well as investments in the ordinary shares of Barclays Bank UK PLC of £14,245m (2021: 14,245m) and their AT1 securities of £2,570m (2021: £2,570m). The increase of £2,016m during the year was driven by a capital injection of £750m and an increase in the AT1 holdings and associated fair value which totalled £998m. Impairment in subsidiaries At the end of each reporting period an impairment review is undertaken in respect of investment in the ordinary shares of subsidiaries. Where impairment may be indicated a test of the carrying value against the recoverable value is performed; impairment being 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 attributable profit based on financial budgets approved by management, covering a five year period as an approximation of future cash flows discounted using a pre-tax discount rate appropriate to the subsidiary being tested. A terminal growth rate has then been applied to the cash flows thereafter which is based upon expectations of future inflation rates. The 2022 review identified the value in use calculated was higher than the carrying value for all subsidiaries. Due to the improved market conditions and interest rate environment for the Group’s UK banking business in December 2021 compared to December 2020, the review further identified that the accumulated impairment for the investment in Barclays Bank UK PLC of £2,573m no longer existed. The VIU of Barclays Bank UK PLC was found to be significantly higher than both the carrying amount of the investment and the gross cost of the investment and hence all accumulated impairment was reversed in December 2021. For Barclays Bank UK PLC, a discount rate of 14.5% was applied to the cash flow forecast in December 2021 (2020: 13.8%). In determining the discount rate, management identified a cost of equity associated with market participants that closely resemble the subsidiary and adjusted for tax to arrive at the pre-tax equivalent rate. A terminal growth rate of 2.0% was used to calculate a terminal value for the investment based on inflation rates to approximate future long term growth in December 2021 (2020:2.0%). Loans and advances in subsidiaries During the year loans and advances to subsidiaries increased by £1,556m to £23,628m (2021: £22,072m). The increase was largely driven by £4,487m new intra-group loans to Barclays PLC subsidiaries and foreign exchange impact of £1,663m due to the depreciation of GBP largely against USD. This was partially offset by the maturity of intra-group loans to Barclays PLC subsidiaries of £4,765m. Subordinated liabilities and debt securities in issue During the year, Barclays PLC issued £1,000m of Fixed Rate Resetting Subordinated Callable Notes, which are included within the subordinated liabilities balance of £11,230m (2021: £9,301m). Debt securities in issue of £24,086m (2021: £25,658m) have reduced during the year primarily due to net maturities of £2,969m senior issuances partially offset by foreign exchange impact of £1,404m due to the depreciation of GBP largely against USD. Management of internal investments Barclays PLC retains the discretion to manage the nature of its internal investments in subsidiaries according to their regulatory and business needs. Barclays PLC may invest capital and funding into Barclays Bank PLC, Barclays Bank UK PLC and other Group subsidiaries such as Barclays Execution Services Limited and the US Intermediate Holding Company (IHC). Financial assets and liabilities designated at fair value Financial liabilities designated at fair value of £22,971m (2021: £16,319m) primarily included new issuances during the year of USD 7,250m, EUR 2,250m Fixed Rate Resetting Senior Callable Notes and USD 400m Zero Coupon Callable Notes. The proceeds raised through these transactions were used to invest in subsidiaries of Barclays PLC and are included within the financial assets designated at fair value through the income statement balance of £28,930m (2021: £25,091m). The effect of changes in the liabilities’ fair value, including those due to credit risk, is expected to offset the changes in the fair value of the related financial asset in the income statement The difference between the financial liabilities’ carrying amount and the contractual amount on maturity is £2,100m (2021: £271m). Derivative financial instruments During the year derivative financial liabilities increased by £863m to £906m (2021: £43m). The increase in the year is primarily driven by the rising rate environment. Total equity Called up share capital and share premium Called up share capital and share premium of Barclays PLC is £4,373m (2021: £4,536m). The decrease in the year is primarily due to 931m shares repurchased with a total nominal value of £233m. This decrease was offset by shares issued under employee share schemes. Other equity instruments Other equity instruments of £13,250m (2021: £12,241m) comprises AT1 securities issued by Barclays PLC. 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. During the year there were three issuances with principal amounts totalling £1,250m, $2,000m, SGD450m and redemptions with principal amounts totalling £1,000m and $1,500m.

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 Group, and the separate financial statements of Barclays PLC, have been prepared in accordance with UK-adopted international accounting standards. The consolidated financial statements of the Group, and the separate financial statements of Barclays PLC, have also been prepared in accordance with 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. 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.
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. These financial statements are stated in millions of Pounds Sterling (£m), the functional currency of Barclays PLC. The financial statements have been prepared for Barclays PLC and its subsidiaries (the Group) under Section 399 of 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 Group and the 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 includes a review of a working capital report (WCR). The WCR is used by the Board to assess the future performance of the Group and that it has the resources in place that are required to meet its ongoing regulatory requirements. The assessment is based upon business plans which contain future projections of profitability taken from the 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 Group could experience. The WCR showed that the 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 Directors concluded that there was a reasonable expectation that the Group and parent company 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 Group applies IFRS 10 Consolidated financial statements. The consolidated financial statements combine the financial statements of Barclays PLC and all its subsidiaries. Subsidiaries are entities over which Barclays PLC has control. The Group has control over another entity when the 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. The assessment of control is based on the consideration of all facts and circumstances. The Group reassesses whether it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control. Intra-group transactions and balances are eliminated on consolidation. Consistent accounting policies are used throughout the Group for the purposes of the consolidation. Changes in ownership interests in subsidiaries are accounted for as equity transactions if they occur after control has already been obtained and they do not result in loss of control. As the consolidated financial statements include partnerships where the 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 34.
Foreign currency translation	Foreign currency translation The Group applies IAS 21 The Effects of Changes in Foreign Exchange Rates. 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. Non-monetary foreign currency balances in relation to items measured in terms of historical cost are carried at historical transaction date exchange rates. Non-monetary foreign currency balances in relation to items measured at fair value are translated using the exchange rate at the date when the fair value was measured. The 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 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 The Group applies IFRS 9 Financial Instruments to the recognition, classification and measurement, and derecognition of financial assets and financial liabilities and the impairment of financial assets. The Group applies the requirements of IAS 39 Financial Instruments: Recognition and Measurement for hedge accounting purposes. Recognition The 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 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. In assessing whether contractual cash flows are SPPI compliant, interest is defined as consideration primarily for the time value of money and the credit risk of the principal outstanding. The time value of money is defined as the element of interest that provides consideration only for the passage of time and not consideration for other risks or costs associated with holding the financial asset. 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 and (iii) features that could modify the time value of money. Financial assets are measured at amortised cost if they are held within a business model whose objective is to hold financial assets in order to collect contractual cash flows, and their contractual cash flows represent SPPI. Financial assets are measured at fair value through other comprehensive income if they are held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets, and their contractual cash flows represent SPPI. Other financial assets are measured at fair value through profit and loss. There is an option to make an irrevocable election on initial recognition for non-traded equity investments to be measured at fair value through other comprehensive income, in which case dividends are recognised in profit or loss, but gains or losses are not reclassified to profit or loss upon derecognition, and the impairment requirements of IFRS 9 do not apply. The accounting policy for each type of financial asset or liability is included within the relevant note for the item. The Group’s policies for determining the fair values of the assets and liabilities are set out in Note 17. Derecognition The 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 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 reward have been transferred or retained, where control over the asset has been lost. Financial liabilities are derecognised 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. Transactions in which the Group transfers assets and liabilities, portions of them, or financial risks associated with them can be complex and it may not be obvious whether substantially all of the risks and rewards have been transferred. It is often necessary to perform a quantitative analysis. Such an analysis compares the 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 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 Group obtains such loans or cash collateral, in exchange for the transfer of collateral. The 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 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 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 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 The Group applies IAS 32, Financial Instruments: Presentation, to determine whether funding is either a financial liability (debt) or equity. Issued financial instruments or their components are classified as liabilities if the contractual arrangement results in the 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.
Changes in the basis for determining contractual cash flows resulting from interest rate benchmark reform	Changes in the basis for determining contractual cash flows resulting from interest rate benchmark reform A change in the basis of determining the contractual cash flows of a financial instrument that is required by interest rate benchmark reform is accounted for by updating the effective interest rate, without the recognition of an immediate gain or loss. This practical expedient is only applied where (1) the change to the contractual cash flows is necessary as a direct consequence of the reform and (2) the new basis for determining the contractual cash flows is economically equivalent to the previous basis. For changes made in addition to those required by the interest rate benchmark reform, the practical expedient is applied first, after which the normal IFRS 9 requirements for modifications of financial instruments is applied. Refer to Note 14 for further details regarding hedge accounting policies in respect of interest rate benchmark reform. Refer to Note 41 for further disclosure related to interest rate benchmark reform.
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. Repurchase and reverse repurchase agreements are not considered to be part of cash equivalents. Investments in debt securities at amortised cost, presented within loans and advances on the balance sheet, are deemed to be investing activities for the purposes of the cash flow statement, except those instruments considered to be cash equivalents. Debt securities issued and redeemed are considered to be operating activities, except qualifying eligible liabilities that satisfy regulatory requirements for MREL instruments (or have previously satisfied these requirements since 2019 when they came into effect), which are considered to be financing activities.
New and amended standards and interpretations	New and amended standards and interpretations The accounting policies adopted have been consistently applied. Future accounting developments The following accounting standards have been issued by the IASB but are not yet effective: IFRS 17 – Insurance contracts In May 2017, the IASB issued IFRS 17 Insurance Contracts, a comprehensive new accounting standard for insurance contracts covering recognition and measurement, presentation and disclosure. IFRS 17 will replace IFRS 4 Insurance Contracts that was issued in 2005. In June 2020, the IASB published amendments to IFRS 17, to include scope exclusion for certain credit card contracts and similar contracts that provide insurance coverage, the optional scope exclusion for loan contracts that transfer significant insurance risk, and the clarification that only financial guarantees issued are in scope of IFRS 9. IFRS 17 applies to all types of insurance contracts (i.e. life, non-life, direct insurance and reinsurance), regardless of the type of entities that issue them, as well as to certain guarantees and financial instruments with discretionary participation features. A few scope exceptions will apply. IFRS 17 is effective for accounting periods beginning on or after 1 January 2023. The Group does not expect the impact of IFRS 17 to be material. 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 of 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 twelve 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. Disclosure of Accounting Policies - Amendments to IAS 1 and IFRS Practice Statement 2 In February 2021 the IASB issued amendments to IAS 1 that require entities to disclose their material accounting policies rather than their significant accounting policies. The amendments to IFRS Practice Statement 2 provide guidance on the concept of materiality and its application to accounting policy information. Under the amendments, accounting policy information is material if, when considered together with other information included in an entity’s financial statements, it can reasonably be expected to influence decisions that the primary users of general purpose financial statements make on the basis of those financial statements. The amendments are effective for annual periods beginning on or after 1 January 2023, and will be applied from that date. Definition of Accounting Estimate - Amendments to IAS 8 In February 2021 the IASB issued amendments to IAS 8 that replace the definition of a change in accounting estimates with a definition of accounting estimates. Under the new definition, accounting estimates are clarified as monetary amounts in financial statements that are subject to measurement uncertainty. Where an entity's accounting policy requires an item to be measured at monetary amounts that cannot be observed directly, it should develop an accounting estimate to achieve this objective. The amendments are effective for annual periods beginning on or after 1 January 2023, and will be applied from that date.
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. Critical accounting estimates and judgements are disclosed in: ▪ Credit impairment charges on page 342 ▪ Tax on page 346 ▪ Fair value of financial instruments on page 362 ▪ Goodwill and intangible assets on page 379 ▪ Pensions and post-retirement benefit obligations on page 400 ▪ Provisions including conduct and legal, competition and regulatory matters on page 383
Presentation of segmental reporting	Presentation of segmental reporting The Group’s segmental reporting is in accordance with IFRS 8 Operating Segments . Operating segments are reported in a manner consistent with the internal reporting provided to the Executive Committee, which is responsible for allocating resources and assessing performance of the operating segments, and has been identified as the chief operating decision maker. All transactions between business segments are conducted on an arm’s-length basis, with intra-segment revenue and costs being eliminated in Head Office. Income and expenses directly associated with each segment are included in determining business segment performance.
Accounting for interest income and expense	Accounting for interest income and expenses Interest income on loans and advances at amortised cost and financial assets at fair value through other comprehensive income, and 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 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 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 Group applies IFRS 15 Revenue from Contracts with Customers. IFRS 15 establishes a five-step model governing revenue recognition. The five-step model requires the Group to (i) identify the contract with the customer, (ii) identify each of the performance obligations included in the contract, (iii) determine the amount of consideration in the contract, (iv) allocate the consideration to each of the identified performance obligations and (v) recognise revenue as each performance obligation is satisfied.
Accounting for net trading income	Accounting for net trading income In accordance with IFRS 9, 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. 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 where the business model is to manage assets and liabilities on a fair value basis which includes use of derivatives or where an instrument is designated at fair value to eliminate an accounting mismatch and the related instrument's gain and losses are reported in net trading income.
Accounting for net investment income	Accounting for net investment income/(expense) Dividends are recognised when the right to receive the dividend has been established. Other accounting policies relating to net investment income are set out in Note 13 and Note 15.
Accounting for the impairment of financial assets	Accounting for the impairment of financial assets Impairment In accordance with IFRS 9, the 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. 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 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 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 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 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 reassigned 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. The Group uses a five-scenario model to calculate ECL. An external consensus forecast is assembled from key sources, including HM Treasury (short and medium-term forecasts) and Bloomberg (based on median of economic forecasts), which forms the Baseline scenario. In addition, two adverse scenarios (Downside 1 and Downside 2) and two favourable scenarios (Upside 1 and Upside 2) are derived, with associated probability weightings. The adverse scenarios are calibrated to a broadly similar severity to the Group's internal stress tests and stress scenarios provided by regulators whilst also considering IFRS 9 specific sensitivities and non-linearity. The favourable scenarios are designed to reflect plausible upside risks to the Baseline scenario which are broadly consistent with the economic narrative approved by the Senior Scenario Review Committee. All scenarios are regenerated at a minimum semi-annually. The scenarios include key economic variables (including GDP, unemployment, House Price Index (HPI) and base rates in both the UK and US markets) and expanded variables using statistical models based on historical correlations. The upside and downside shocks are designed to evolve over a five-year stress horizon, with all five scenarios converging to a steady state after approximately seven years. The methodology for estimating probability weights for each of the scenarios involves a comparison of the distribution of key historical UK and US macroeconomic variables against the forecast paths of the five scenarios. The methodology works such that the baseline (reflecting current consensus outlook) has the highest weight and the weights of adverse and favourable scenarios depend on the deviation from the baseline; the further from the baseline, the smaller the weight. A single set of five scenarios is used across all portfolios and all five weights are normalised to equate to 100%. The same scenarios used in the estimation of expected credit losses are also used to inform Barclays' internal planning. The impacts across the portfolios are different because of the sensitivities of each of the portfolios to specific macroeconomic variables, for example, mortgages are highly sensitive to house prices, and credit cards and unsecured consumer loans are highly sensitive to unemployment. 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. Uncollectable loans are written off against the related allowance for loan impairment on completion of the 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 Group may enter into a financial guarantee contract which requires the issuer of such contract to reimburse the 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 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. Note 1 sets out details for changes in the basis of determining the contractual cash flows of a financial instrument that are required by interest rate benchmark reform. 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 revolving 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 The regulatory Basel Committee of Banking Supervisors (BCBS) ECL calculations are leveraged for IFRS 9 modelling but adjusted for key differences which include: ▪ BCBS requires 12 month through the economic cycle losses whereas IFRS 9 requires 12 months or lifetime point in time losses based on conditions at the reporting date and multiple forecasts of the future economic conditions over the expected lives; ▪ IFRS 9 models do not include certain conservative BCBS model floors and downturn assessments and require discounting to the reporting date at the original EIR rather than using the cost of capital to the date of default; ▪ Management adjustments are made to modelled output to account for situations where known or expected risk factors and information have not been considered in the modelling process, for example forecast economic scenarios for uncertain political events; and ▪ ECL is measured at the individual financial instrument level, however a collective approach where financial instruments with similar risk characteristics are grouped together, with apportionment to individual financial instruments, is used where effects can only be seen at a collective level, for example for forward-looking information. For the IFRS 9 impairment assessment, the Group’s risk models are used to determine the PD, LGD and EAD. For Stage 2 and 3, the Group applies lifetime PDs but uses 12 month PDs for Stage 1. The ECL drivers of PD, EAD and LGD are modelled at an account level which considers vintage, among other credit factors. Also, the assessment of significant increase in credit risk is based on the initial lifetime PD curve, which accounts for the different credit risk underwritten over time. 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 definition 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 Group’s experience of managing credit risk. The determination of expected life is most material for Barclays' 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. The impairment charge reflected in the income statement for retail portfolios is £976m (2021: £289m release; 2020: £3,116m charge) of the total impairment charge on loans and advances and off-balance sheet loan commitments and financial guarantee contracts. 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 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. The impairment charge reflected in the financial statements in relation to wholesale portfolios is £207m (2021: £346m release; 2020: £1,569m charge) of the total impairment charge on loans and advances and off-balance sheet loan commitments and financial guarantee contracts. Further information on impairment allowances, impairment charges, management adjustments to models for impairment, measurement uncertainty, sensitivity analysis and related credit information is set out within the Credit risk performance section. Temporary adjustments to calculated IFRS9 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.

Accounting for purchased financial guarantee contracts	The Group may enter into a financial guarantee contract which requires the issuer of such contract to reimburse the 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 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 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 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 Group’s tax returns. The 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 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 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 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 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. 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 In accordance with IFRS 9, 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 insruments at fair value through profit and loss	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 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 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 17.
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 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. This includes terms included in a contract or financial liability (the host), which, had it been a standalone contract, would have met the definition of a derivative. If these are separated from the host, i.e. when the economic characteristics of the embedded derivative are not closely related with those of the host contract and the combined instrument is not measured at fair value through profit or loss, then they are accounted for in the same way as derivatives. For financial assets, the requirements are whether the financial assets contain contractual terms that give rise on specified dates to cash flows that are SPPI, and consequently the requirements for accounting for embedded derivatives are not applicable to financial assets.
Hedge accounting	Hedge accounting The Group applies the requirements of IAS 39 Financial Instruments: Recognition and Measurement for hedge accounting purposes. The 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 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. The Group applies the ‘Amendments to IFRS 9, IAS 39 and IFRS 7 Interest Rate Benchmark Reform’ issued in September 2019 (the Phase 1 amendments). The amendments provide temporary relief from applying specific hedge accounting requirements to hedging relationships directly affected by IBOR (‘Interbank Offered Rates’) reform. The reliefs have the effect that IBOR reform should not generally cause hedge accounting to terminate. However, any hedge ineffectiveness continues to be recorded in the income statement. Furthermore, the amendments set out triggers for when the reliefs will end, which include the uncertainty arising from interest rate benchmark reform no longer being present. In summary, the reliefs provided by the Phase 1 amendments are: ▪ When considering the ‘highly probable’ requirement, the Group has assumed that the IBOR interest rates upon which our hedged items are based do not change as a result of IBOR Reform. ▪ In assessing whether the hedge is expected to be highly effective on a forward-looking basis the Group has assumed that the IBOR interest rates upon which the cash flows of the hedged items and the interest rate swaps that hedge them are based are not altered by IBOR reform. ▪ The Group will not discontinue hedge accounting during the period of IBOR-related uncertainty solely because the retrospective effectiveness falls outside the required 80–125% range. ▪ The Group has not recycled the cash flow hedge reserve relating to the period after the reforms are expected to take effect. ▪ The Group has assessed whether the hedged IBOR risk component is a separately identifiable risk only when it first designates a hedged item in a fair value hedge and not on an ongoing basis. The Group also applies the ‘Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16 Interest Rate Benchmark Reform – Phase 2’ issued in August 2020. The Phase 2 amendments provide relief when changes are made to hedge relationships as a result of the interest rate benchmark reform. In summary, the reliefs provided by the Phase 2 amendments are: ▪ Under a temporary exception, the Group has considered that changes to the hedge designation and hedge documentation due to the interest rate benchmark reform would not constitute the discontinuation of the hedge relationship nor the designation of a new hedging relationship. ▪ In respect of the retrospective hedge effectiveness assessment, the Group may elect, on a hedge-by-hedge basis, to reset the cumulative fair value changes to zero when the exception to the retrospective assessment ends (Phase 1 relief). Any hedge ineffectiveness will continue to be measured and recognised in full in profit or loss. ▪ The Group has deemed the amounts accumulated in the cash flow hedge reserve to be based on the alternative benchmark rate (on which the hedge future cash flows are determined) when there is a change in basis for determining the contractual cash flows. ▪ For hedges of groups of items (such as those forming part of a macro cash flow hedging strategy), the amendments provide relief for items within a designated group of items that are amended for changes directly required by the reform. ▪ In respect of whether a risk component of a hedged item is separately identifiable, the amendments provide temporary relief to entities to meet this requirement when an alternative risk free rate (RFR) financial instrument is designated as a risk component. These amendments allow the Group upon designation of the hedge to assume that the separately identifiable requirement is met if the Group reasonably expects the RFR risk will become separately identifiable within the next 24 months. The Group applies this relief to each RFR on a rate-by-rate basis and starts when the Group first designates the RFR as a non-contractually specified risk component. 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 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 Group’s investment in the operation.
Accounting for financial assets	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 remeasured 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 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 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). Gains or losses on the derecognition of these equity securities are not transferred to profit or loss. These assets are also not subject to the impairment requirements and therefore no amounts are recycled to the income statement. Where the Group has not made the irrevocable election to present subsequent changes in the fair value of the instrument in other comprehensive income, equity securities are measured at fair value through profit or loss.
Accounting for financial liabilities	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 P&L. 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 P&L. On derecognition of the financial liability no amount relating to own credit risk is recycled to the income statement. The 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 Group on the basis of its fair value, or includes terms that have substantive derivative characteristics (Note 14). The details on how the fair value amounts are arrived at for financial liabilities designated at fair value are described in Note 17.
Accounting for financial assets and liabilities - fair values	Accounting for financial assets and liabilities – fair values 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. All financial instruments are initially recognised at fair value on the date of initial recognition (including transaction costs, other than financial instruments held at fair value through profit or loss) and depending on the subsequent classification of the financial asset or liability, may continue to be held at fair value either through profit or loss or other comprehensive income. The fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Wherever possible, fair value is determined by reference to a quoted market price for that instrument. For many of the 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. The best evidence of an instrument’s fair value on initial recognition is typically the transaction price. However, if fair value can be evidenced by comparison with other observable current market transactions in the same instrument, or is based on a valuation technique whose inputs include only data from observable markets, then the instrument should be recognised at the fair value derived from such observable market data. 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 model 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 371 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.
IAS 32 Financial Instruments	In accordance with IAS 32 Financial Instruments: Presentation, t he 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 are not intended to represent the 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 loans and advances and deposits held at amortised cost	Accounting for loans and advances and deposits held at amortised cost Loans and advances to customers and banks, customer accounts, debt securities and most financial liabilities, are held at amortised cost. That is, the initial fair value (which is normally the amount advanced or borrowed) is adjusted for repayments and the amortisation of coupon, fees and expenses to represent the effective interest rate of the asset or liability. Balances deferred on-balance sheet as effective interest rate adjustments are amortised to interest income over the life of the financial instrument to which they relate. Financial assets that are held in a business model to collect the contractual cash flows and that contain contractual terms that give rise on specified dates to cash flows that are SPPI, are measured at amortised cost. The carrying value of these financial assets at initial recognition includes any directly attributable transaction costs. Refer to Note 1 for details on ‘solely payments of principal and interest’. In determining whether the business model is a ‘hold to collect’ model, the objective of the business model must be to hold the financial asset to collect contractual cash flows rather than holding the financial asset for trading or short-term profit taking purposes. While the objective of the business model must be to hold the financial asset to collect contractual cash flows this does not mean the Group is required to hold the financial assets until maturity. When determining if the business model objective is to collect contractual cash flows the Group will consider past sales and expectations about future sales.
Accounting for property, plant and equipment	Accounting for property, plant and equipment The Group applies IAS 16 Property Plant and Equipment and IAS 40 Investment Properties. 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. The Group uses the following annual rates in calculating depreciation: Annual rates in calculating depreciation Depreciation rate Freehold land Not depreciated Freehold buildings and long-leasehold property (more than 50 years to run) 2-3.3% Leasehold property over the remaining life of the lease (less than 50 years to run) 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 Group 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 under IFRS 16 effective from 1 January 2019	Accounting for leases IFRS 16 applies to all leases with the exception of licences of intellectual property, rights held by licensing agreements within the scope of IAS 38 Intangible Assets, service concession arrangements, leases of biological assets within the scope of IAS 41 Agriculture and leases of minerals, oil, natural gas and similar non-regenerative resources . IFRS 16 includes an accounting policy choice for a lessee to elect not to apply IFRS 16 to remaining assets within the scope of IAS 38 Intangible Assets which the Group has decided to apply. When the Group is the lessee, it is required to recognise both: ▪ A lease liability, measured at the present value of remaining cash flows on the lease, and ▪ A right 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. The lease liability is remeasured when there is a change in one of the following: ▪ Future lease payments arising from a change in an index or rate; ▪ The Group’s estimate of the amount expected to be payable under a residual value guarantee; or ▪ The Group’s assessment of whether it will exercise a purchase, extension or termination option. When the lease liability is remeasured, a corresponding adjustment is made to the carrying amount of the ROU asset, or is recorded in the income statement if the carrying amount of the ROU asset has been reduced to nil. On the balance sheet, the ROU assets are included within property, plant and equipment and the lease liabilities are included within other liabilities. The Group applies 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 Group is 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. When the lease is deemed a finance lease, the leased asset is not held on the balance sheet; instead a finance lease receivable is recognised representing the minimum lease payments receivable under the terms of the lease, discounted at the rate of interest implicit in the lease.
Accounting for goodwill and intangible assets	Accounting for goodwill and intangible assets Goodwill The carrying value of goodwill is determined in accordance with IFRS 3 Business Combinations and IAS 36 Impairment of Assets . Goodwill arising on the acquisition of subsidiaries represents the excess of the fair value of the purchase consideration over the fair value of the 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 a 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 CGU's fair value if this is higher. Intangible assets Intangible assets other than goodwill are accounted for in accordance with IAS 38 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 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 a 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 a Exceptions to the above rate relate to useful lives of certain core banking platforms that are assessed individually and, if appropriate, amortised over longer periods ranging from 10 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 The Group applies IAS 37 Provisions, Contingent Liabilities and Contingent Assets in accounting for non-financial liabilities. 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. Provision is made for the anticipated cost of restructuring, including redundancy costs, when an obligation exists; for example, when the 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. 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 complexity of such matters often requires the input of specialist professional advice in making assessments to produce estimates. Customer redress and legal, competition and regulatory matters are areas where a higher degree of professional judgement is required. 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 26 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.
Accounting for staff costs, pensions and post-retirement benefits	Accounting for staff costs The Group applies IAS 19 Employee benefits in its accounting for most of the components of staff costs. Short-term employee benefits – salaries, accrued performance costs and social security are recognised over the period in which the employees provide the services to which the payments relate. Performance costs – recognised to the extent that the Group has a present obligation to its employees that can be measured reliably and are recognised over the period of service that employees are required to work to qualify for the payments. Deferred cash and share awards are made to employees to incentivise performance over the period employees provide services. To receive payment under an award, employees must provide service over the vesting period. The period over which the expense for deferred cash and share awards is recognised is based upon the period employees consider their services contribute to the awards. For past awards, the Group considers that it is appropriate to recognise the awards over the period from the date of grant to the date that the awards vest. In relation to awards granted from 2017, the Group, taking into account the changing employee understanding surrounding those awards, considered it appropriate for expense to be recognised 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 32 and Note 33 respectively. Accounting for pensions and post-retirement benefits The Group operates a number of pension schemes and post-employment benefit schemes. Defined contribution schemes – the 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 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 Group, using a methodology similar to that for defined benefit pension schemes.
Accounting for share-based payments	Accounting for share-based payments The Group applies IFRS 2 Share-based Payments in accounting for employee remuneration in the form of shares. 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. 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.
Accounting for investment in subsidiaries	Accounting for investment in subsidiaries In the individual financial statements of Barclays PLC, investments in subsidiaries are stated at cost less impairment.
Accounting for associates and joint ventures	Accounting for associates and joint ventures The Group applies IAS 28 Investments in Associates and IFRS 11 Joint Arrangements. Associates are entities in which the Group has significant influence, but not control, over the operating and financial policies. Generally the Group holds more than 20% but less than 50% of their voting shares. Joint ventures are arrangements where the Group has joint control and rights to the net assets of the entity.
Accounting for securitisations	Accounting for securitisations The 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 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 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 Group balance sheet, for example because Barclays retains substantially all the exposure to those assets under an agreement to repurchase them in the future for a fixed price. Assets pledged or transferred as collateral include all assets categorised as encumbered in the disclosure on pages 180 to 182 of the Barclays PLC Pillar 3 Report 2022 (unaudited), other than those held in commercial paper conduits. In these transactions, the Group will be required to step in to provide financing itself under a liquidity facility if the vehicle cannot access the commercial paper market. 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 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.

Loans and advances at amortised cost by stage and product (audited)	The table below presents a stage allocation and business segment analysis of loans and advances at amortised cost by gross exposure, impairment allowance, impairment charge and coverage ratio as at 31 December 2022. Also included are stage allocation of off-balance sheet loan commitments and financial guarantee contracts by gross exposure, impairment allowance and coverage as at 31 December 2022. Impairment allowance under IFRS 9 considers both the drawn and the undrawn counterparty exposure. For retail portfolios, the total impairment allowance is allocated to gross loans and advances to the extent allowance does not exceed the drawn exposure and any excess is reported on the liabilities side of the balance sheet as a provision. For wholesale portfolios, impairment allowance on undrawn exposure is reported on the liability side of the balance sheet as a provision.

Credit risk profile by internal PD band for loans and advances at amortised cost, contingent liabilities and loan commitments (audited)	Credit exposures by internal PD grade The below tables represent credit risk profile 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 (see Note 8), 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.
Contractual maturity of financial assets and liabilities (audited)	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 ‘on demand’ column at their fair value. Liquidity risk on these items is not managed on the basis of contractual maturity since they 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.

This is in addition to a £5bn transaction executed in 2020. In total, over three-quarters of the longevity risk for current pensioners has been reinsured, and the transactions will provide income to the UKRF in the event that pensions are paid out for longer than expected. The contracts form part of the UKRF’s investment portfolio. At 31 December 2022, the contracts are valued at £(123)m (2021: nil). The negative value placed on the longevity reinsurance contracts at 31 December 2022 reflects the estimated impact of changes in the reinsurance market, demographic assumptions and risk premia since the 2020 transaction was entered into by the UKRF. The 2022 transaction is valued at nil as it is assessed to have been transacted recently at fair value. 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 Barclays expressing any specific view of the probability of such movements happening.
