BASIS OF PREPARATION

Disclosure of basis of preparation of financial statements [Abstract]
BASIS OF PREPARATION	NOTE 1: BASIS OF PREPARATION The consolidated financial statements of Lloyds Banking Group plc and its subsidiary undertakings (the Group) have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (IASB). The financial information has been prepared under the historical cost convention, as modified by the revaluation of investment properties, financial assets measured at fair value through other comprehensive income, trading securities and certain other financial assets and liabilities at fair value through profit or loss and all derivative contracts. The directors consider that it is appropriate to continue to adopt the going concern basis in preparing the financial statements. In reaching this assessment, the directors have considered the impact of climate change upon the Group’s performance and projected funding and capital position. The directors have also taken into account the results from stress testing scenarios. Details of those IFRS pronouncements which will be relevant to the Group but which were not effective at 31 December 2022 and which have not been applied in preparing these financial statements are given in note 55. In April 2022, the IFRS Interpretations Committee was asked to consider whether an entity includes a demand deposit as a component of cash and cash equivalents in the statement of cash flows when the demand deposit is subject to contractual restrictions on use agreed with a third party. It concluded that such amounts should be included within cash and cash equivalents. Accordingly, the Group includes mandatory reserve deposits with central banks that are held in demand accounts within cash and cash equivalents disclosed in the cash flow statement. This change has increased the Group’s cash and cash equivalents at 1 January 2020 by £1,696 million (to £59,507 million) and decreased the adjustment for the change in operating assets in 2020 by £982 million (to a reduction of £17,668 million) resulting in an increase in the Group’s cash and cash equivalents at 31 December 2020 of £2,678 million (to £78,145 million); and decreased the adjustment for the change in operating assets in 2021 by £137 million (to a reduction of £10,365 million) and, as a result, the Group’s cash and cash equivalents at 31 December 2021 increased by £2,815 million (to £79,194 million). The change had no impact on profit after tax, total equity or the Group’s earnings per share. In 2021, the Group adopted the Interest Rate Benchmark Reform Phase 2 amendments issued by the IASB. These amendments require that changes to expected future cash flows that both arise as a direct result of IBOR Reform and are economically equivalent to the previous cash flows are accounted for as a change to the effective interest rate with no adjustment to the asset’s or liability’s carrying value; no immediate gain or loss is recognised. The requirements also provide relief from the requirements to discontinue hedge accounting as a result of amending hedge documentation if the changes are required solely as a result of IBOR Reform. The following change has been made to the presentation of the Group’s assets on the face of the balance sheet: • Reinsurance assets are shown separately from other assets There has been no change in the basis of accounting for any of the underlying transactions. Comparatives have been presented on a consistent basis.

ACCOUNTING POLICIES

ACCOUNTING POLICIES	12 Months Ended

Disclosure of significant accounting policies [Abstract]
ACCOUNTING POLICIES	NOTE 2: ACCOUNTING POLICIES The Group’s accounting policies are set out below. These accounting policies have been applied consistently. (A) Consolidation The assets, liabilities and results of Group undertakings (including structured entities) are included in the financial statements on the basis of accounts made up to the reporting date. Group undertakings include subsidiaries, associates and joint ventures. (1) Subsidiaries Subsidiaries are entities controlled by the Group. The Group controls an entity when it has power over the entity, is exposed to, or has rights to, variable returns from its involvement with the entity, and has the ability to affect those returns through the exercise of its power. This generally accompanies a shareholding of more than one half of the voting rights although in certain circumstances a holding of less than one half of the voting rights may still result in the ability of the Group to exercise control. The existence and effect of potential voting rights that are currently exercisable or convertible are considered when assessing whether the Group controls another entity. The Group reassesses whether or not it controls an entity if facts and circumstances indicate that there have been changes to any of the above elements. Subsidiaries are fully consolidated from the date on which control is transferred to the Group; they are de-consolidated from the date that control ceases. The Group consolidates collective investment vehicles if its beneficial ownership interests give it substantive rights to remove the external fund manager of the investment activities of the fund. Where a subsidiary of the Group is the fund manager of a collective investment vehicle, the Group considers a number of factors in determining whether it acts as principal, and therefore controls the collective investment vehicle, including: an assessment of the scope of the Group’s decision-making authority over the investment vehicle; the rights held by other parties including substantive removal rights without cause over the Group acting as fund manager; the remuneration to which the Group is entitled in its capacity as decision-maker; and the Group’s exposure to variable returns from the beneficial interest that it holds in the investment vehicle. Consolidation may be appropriate in circumstances where the Group has less than a majority beneficial interest. Where a collective investment vehicle is consolidated the interests of parties other than the Group are reported in other liabilities and the movement in those interests in interest expense. Structured entities are entities that are designed so that their activities are not governed by way of voting rights. In assessing whether the Group has power over such entities in which it has an interest, the Group considers factors such as the purpose and design of the entity; its practical ability to direct the relevant activities of the entity; the nature of the relationship with the entity; and the size of its exposure to the variability of returns of the entity. The treatment of transactions with non-controlling interests depends on whether, as a result of the transaction, the Group loses control of the subsidiary. Changes in the parent’s ownership interest in a subsidiary that do not result in a loss of control are accounted for as equity transactions; any difference between the amount by which the non-controlling interests are adjusted and the fair value of the consideration paid or received is recognised directly in equity and attributed to the owners of the parent entity. Where the Group loses control of the subsidiary, at the date when control is lost the amount of any non-controlling interest in that former subsidiary is derecognised and any investment retained in the former subsidiary is remeasured to its fair value; the gain or loss that is recognised in profit or loss on the partial disposal of the subsidiary includes the gain or loss on the remeasurement of the retained interest. Intercompany transactions, balances and unrealised gains and losses on transactions between Group companies are eliminated. The acquisition method of accounting is used to account for business combinations by the Group. The consideration for the acquisition of a subsidiary is the fair value of the assets transferred, the liabilities incurred and the equity interests issued by the Group. The consideration includes the fair value of any asset or liability resulting from a contingent consideration arrangement. Acquisition-related costs are expensed as incurred except those relating to the issuance of debt instruments (see (E)(4) below) or share capital (see (P) below). Identifiable assets acquired and liabilities assumed in a business combination are measured initially at their fair value at the acquisition date. (2) Joint ventures and associates Joint ventures are joint arrangements over which the Group has joint control with other parties and has rights to the net assets of the arrangements. Joint control is the contractually agreed sharing of control of an arrangement and only exists when decisions about the relevant activities require the unanimous consent of the parties sharing control. Associates are entities over which the Group has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the entity, but is not control or joint control of those policies, and is generally achieved through holding between 20 per cent and 50 per cent of the voting share capital of the entity. The Group utilises the venture capital exemption for investments where significant influence or joint control is present and the business unit operates as a venture capital business. These investments are designated on initial recognition at fair value through profit or loss. Otherwise, the Group’s investments in joint ventures and associates are accounted for using the equity method of accounting. (B) Goodwill Goodwill arises on business combinations and represents the excess of the cost of an acquisition over the fair value of the Group’s share of the identifiable assets, liabilities and contingent liabilities acquired. Where the fair value of the Group’s share of the identifiable assets, liabilities and contingent liabilities of the acquired entity is greater than the cost of acquisition, the excess is recognised immediately in the income statement. Goodwill is recognised as an asset at cost and is tested at least annually for impairment. For impairment testing, goodwill is allocated to the cash generating unit (CGU) or groups of CGUs that are expected to benefit from the business combination. The Group's CGUs are largely product based for its Retail and Insurance businesses and client based for its Commercial Banking business. An impairment loss is recognised if the carrying amount of a CGU is determined to be greater than its recoverable amount. The recoverable amount of a CGU is the higher of its fair value less costs to sell and its value in use. If an impairment is identified the carrying value of the goodwill is written down immediately through the income statement and this is not subsequently reversed. At the date of disposal of a subsidiary, the carrying value of attributable goodwill is included in the calculation of the profit or loss on disposal. (C) Other intangible assets Intangible assets which have been determined to have a finite useful life are amortised on a straight-line basis over their estimated useful life as follows: up to 7 years for capitalised software; 10 to 15 years for brands and other intangible assets. Intangible assets with finite useful lives are reviewed at each reporting date to assess whether there is any indication that they are impaired. If any such indication exists the recoverable amount of the asset is determined and in the event that the asset’s carrying amount is greater than its recoverable amount, it is written down immediately. Certain brands have been determined to have an indefinite useful life and are not amortised. Such intangible assets are assessed annually to determine whether the asset is impaired and to reconfirm that an indefinite useful life remains appropriate. In the event that an indefinite life is inappropriate, a finite life is determined and a further impairment review is performed on the asset. (D) Revenue recognition (1) Net interest income Interest income and expense are recognised in the income statement using the effective interest method for all interest-bearing financial instruments, except for those classified at fair value through profit or loss. The effective interest method is a method of calculating the amortised cost of a financial asset or liability and of allocating the interest income or interest expense over the expected life of the financial instrument. The effective interest rate is the rate that exactly discounts the estimated future cash payments or receipts over the expected life of the financial instrument to the gross carrying amount of the financial asset (before adjusting for expected credit losses) or to the amortised cost of the financial liability, including early redemption fees, other fees, and premiums and discounts that are an integral part of the overall return. In the case of financial assets that are purchased or originated credit-impaired, the effective interest rate is the rate that discounts the estimated future cash flows to the amortised cost of the instrument. Direct incremental transaction costs related to the acquisition, issue or disposal of a financial instrument are also taken into account. Interest income from non-credit impaired financial assets is recognised by applying the effective interest rate to the gross carrying amount of the asset; for credit impaired financial assets, the effective interest rate is applied to the net carrying amount after deducting the allowance for expected credit losses. Impairment policies are set out in (H) below. (2) Fee and commission income and expense Fees and commissions receivable which are not an integral part of the effective interest rate are recognised as income as the Group fulfils its performance obligations. The Group’s principal performance obligations arising from contracts with customers are in respect of value added current accounts, credit cards and debit cards. These fees are received, and the Group provides the service, monthly; the fees are recognised in income on this basis. The Group also receives certain fees in respect of its asset finance business where the performance obligations are typically fulfilled towards the end of the customer contract; these fees are recognised in income on this basis. Where it is unlikely that the loan commitments will be drawn, loan commitment fees are recognised in fee and commission income over the life of the facility, rather than as an adjustment to the effective interest rate for the lending expected to be drawn. Incremental costs incurred to generate fee and commission income are charged to fee and commission expense as they are incurred. (3) Other Dividend income is recognised when the right to receive payment is established. Revenue recognition policies specific to trading income are set out in (E)(3) below; those relating to life insurance and general insurance business are detailed below (see (M) below); and those relating to leases are set out in (J)(1) below. (E) Financial assets and liabilities On initial recognition, financial assets are classified as measured at amortised cost, fair value through other comprehensive income or fair value through profit or loss, depending on the Group’s business model for managing those financial assets and whether the resultant cash flows represent solely payments of principal and interest. The Group assesses its business models at a portfolio level based on its objectives for the relevant portfolio, how the performance of the portfolio is managed and reported, and the frequency of asset sales. Financial assets with embedded derivatives are considered in their entirety when considering their cash flow characteristics. The Group reclassifies financial assets only when its business model for managing those assets changes. A reclassification will only take place when the change is significant to the Group’s operations and will occur at a portfolio level and not for individual instruments; reclassifications are expected to be rare. Equity investments are measured at fair value through profit or loss unless the Group elects at initial recognition to account for the instruments at fair value through other comprehensive income. For these instruments, principally strategic investments, dividends are recognised in profit or loss but fair value gains and losses are not subsequently reclassified to profit or loss following derecognition of the investment. The Group initially recognises loans and advances, deposits, debt securities in issue and subordinated liabilities when the Group becomes a party to the contractual provisions of the instrument. Regular way purchases and sales of securities and other financial assets and trading liabilities are recognised on trade date, being the date that the Group is committed to purchase or sell an asset. Financial assets are derecognised when the contractual right to receive cash flows from those assets has expired or when the Group has transferred its contractual right to receive the cash flows from the assets and either: substantially all of the risks and rewards of ownership have been transferred; or the Group has neither retained nor transferred substantially all of the risks and rewards, but has transferred control. Financial liabilities are derecognised when the obligation is discharged, cancelled or expires. (1) Financial instruments measured at amortised cost Financial assets that are held to collect contractual cash flows where those cash flows represent solely payments of principal and interest are measured at amortised cost. A basic lending arrangement results in contractual cash flows that are solely payments of principal and interest on the principal amount outstanding. Where the contractual cash flows introduce exposure to risks or volatility unrelated to a basic lending arrangement such as changes in equity prices or commodity prices, the payments do not comprise solely principal and interest. Financial assets measured at amortised cost are predominantly loans and advances to customers and banks, reverse repurchase agreements and certain debt securities used by the Group to manage its liquidity. Loans and advances and reverse repurchase agreements are initially recognised when cash is advanced to the borrower at fair value inclusive of transaction costs. Interest income is accounted for using the effective interest method (see (D) above). Financial liabilities are measured at amortised cost, except for trading liabilities and other financial liabilities designated at fair value through profit or loss on initial recognition which are held at fair value. Where changes are made to the contractual cash flows of a financial asset or financial liability that are economically equivalent and arise as a direct consequence of interest rate benchmark reform, the Group updates the effective interest rate and does not recognise an immediate gain or loss. (2) Financial assets measured at fair value through other comprehensive income Financial assets that are held to collect contractual cash flows and for subsequent sale, where the assets’ cash flows represent solely payments of principal and interest, are recognised in the balance sheet at their fair value, inclusive of transaction costs. Interest calculated using the effective interest method and foreign exchange gains and losses on assets denominated in foreign currencies are recognised in the income statement. All other gains and losses arising from changes in fair value are recognised directly in other comprehensive income, until the financial asset is either sold or matures, at which time the cumulative gain or loss previously recognised in other comprehensive income is recognised in the income statement; other than in respect of equity shares, for which the cumulative revaluation amount is transferred directly to retained profits. The Group recognises a charge for expected credit losses in the income statement (see (H) below). As the asset is measured at fair value, the charge does not adjust the carrying value of the asset, and this is reflected in other comprehensive income. (3) Financial instruments measured at fair value through profit or loss Financial assets are classified at fair value through profit or loss where they do not meet the criteria to be measured at amortised cost or fair value through other comprehensive income or where they are designated at fair value through profit or loss to reduce an accounting mismatch. All derivatives are carried at fair value through profit or loss, other than those in effective cash flow and net investment hedging relationships. Derivatives are carried on the balance sheet as assets when their fair value is positive and as liabilities when their fair value is negative. Refer to note 49(3) (Financial instruments: Financial assets and liabilities carried at fair value) for details of valuation techniques and significant inputs to valuation models. Derivatives embedded in a financial asset are not considered separately; the financial asset is considered in its entirety when determining whether its cash flows are solely payments of principal and interest. Derivatives embedded in financial liabilities and insurance contracts (unless the embedded derivative is itself an insurance contract) are treated as separate derivatives when their economic characteristics and risks are not closely related to those of the host contract and the host contract is not carried at fair value through profit or loss. These embedded derivatives are measured at fair value with changes in fair value recognised in the income statement. In accordance with IFRS 4 Insurance Contracts , a policyholder’s option to surrender an insurance contract for a fixed amount is not treated as an embedded derivative. The assets backing the insurance and investment contracts issued by the Group do not meet the criteria to be measured at amortised cost or fair value through other comprehensive income as they are managed on a fair value basis and accordingly are measured at fair value through profit or loss. Similarly, trading securities, which are debt securities and equity shares acquired principally for the purpose of selling in the short term or which are part of a portfolio which is managed for short-term gains, do not meet these criteria and are also measured at fair value through profit or loss. Financial assets measured at fair value through profit or loss are recognised in the balance sheet at their fair value. Fair value gains and losses together with interest coupons and dividend income are recognised in the income statement within net trading income. Financial liabilities are measured at fair value through profit or loss where they are trading liabilities or where they are designated at fair value through profit or loss in order to reduce an accounting mismatch; where the liabilities are part of a group of liabilities (or assets and liabilities) which is managed, and its performance evaluated, on a fair value basis; or where the liabilities contain one or more embedded derivatives that significantly modify the cash flows arising under the contract and would otherwise need to be separately accounted for. Financial liabilities measured at fair value through profit or loss are recognised in the balance sheet at their fair value. Fair value gains and losses are recognised in the income statement within net trading income in the period in which they occur, except in the case of financial liabilities designated at fair value through profit or loss where gains and losses attributable to changes in own credit risk are recognised in other comprehensive income. The fair values of assets and liabilities traded in active markets are based on current bid and offer prices, respectively, which include the expected effects of potential changes to laws and regulations, risks associated with climate change and other factors. If the market is not active the Group establishes a fair value by using valuation techniques. The fair values of derivative financial instruments are adjusted where appropriate to reflect credit risk (via credit valuation adjustments (CVAs), debit valuation adjustments (DVAs) and funding valuation adjustments (FVAs)), market liquidity and other risks. (4) Borrowings Borrowings (which include deposits from banks, customer deposits, repurchase agreements, debt securities in issue and subordinated liabilities) are recognised initially at fair value, being their issue proceeds net of transaction costs incurred. These instruments are subsequently stated at amortised cost using the effective interest method. Preference shares and other instruments which carry a mandatory coupon or are redeemable on a specific date are classified as financial liabilities. The coupon on these instruments is recognised in the income statement as interest expense. Securities which carry a discretionary coupon and have no fixed maturity or redemption date are classified as other equity instruments. Interest payments on these securities are recognised as distributions from equity in the period in which they are paid. An exchange of financial liabilities on substantially different terms is accounted for as an extinguishment of the original financial liability and the recognition of a new financial liability. The difference between the carrying amount of a financial liability extinguished and the new financial liability is recognised in profit or loss together with any related costs or fees incurred. When a financial liability is exchanged for an equity instrument, the new equity instrument is recognised at fair value and any difference between the carrying value of the liability and the fair value of the new equity instrument is recognised in profit or loss. (5) Sale and repurchase agreements (including securities lending and borrowing) Securities sold subject to repurchase agreements (repos) continue to be recognised on the balance sheet where substantially all of the risks and rewards are retained. Funds received for repos carried at fair value are included within trading liabilities. Conversely, securities purchased under agreements to resell (reverse repos), where the Group does not acquire substantially all of the risks and rewards of ownership, are measured at amortised cost or at fair value. Those measured at fair value are recognised within trading securities. The difference between sale and repurchase price is treated as interest and accrued over the life of the agreements using the effective interest method. Securities borrowing and lending transactions are typically secured; collateral takes the form of securities or cash advanced or received. Securities lent to counterparties are retained on the balance sheet. Securities borrowed are not recognised on the balance sheet, unless these are sold to third parties, in which case the obligation to return them is recorded at fair value as a trading liability. Cash collateral given or received is treated as a loan and advance measured at amortised cost or customer deposit. (F) Hedge accounting As permitted by IFRS 9, the Group continues to apply the requirements of IAS 39 to its hedging relationships. Changes in the fair value of all derivative instruments, other than those in effective cash flow and net investment hedging relationships, are recognised immediately in the income statement. As noted in (2) and (3) below, the change in fair value of a derivative in an effective cash flow or net investment hedging relationship is allocated between the income statement and other comprehensive income. Hedge accounting allows one financial instrument, generally a derivative such as a swap, to be designated as a hedge of another financial instrument such as a loan or deposit or a portfolio of such instruments. At the inception of the hedge relationship, formal documentation is drawn up specifying the hedging strategy, the hedged item, the hedging instrument and the methodology that will be used to measure the effectiveness of the hedge relationship in offsetting changes in the fair value or cash flow of the hedged risk. The effectiveness of the hedging relationship is tested both at inception and throughout its life and if at any point it is concluded that it is no longer highly effective in achieving its documented objective, hedge accounting is discontinued. Note 17 provides details of the types of derivatives held by the Group and presents separately those designated in hedge relationships. Where there is uncertainty arising from interest rate benchmark reform, the Group assumes that the interest rate benchmark on which the hedged cash flows and/or the hedged risk are based, or the interest rate benchmark on which the cash flows of the hedging instrument are based, are not altered as a result of interest rate benchmark reform. The Group does not discontinue a hedging relationship during the period of uncertainty arising from the interest rate benchmark reform solely because the actual results of the hedge are not highly effective. Where the contractual terms of a financial asset, financial liability or derivative are amended, on an economically equivalent basis, as a direct consequence of interest rate benchmark reform, the uncertainty arising from the reform is no longer present. In these circumstances, the Group amends the hedge documentation to reflect the changes required by the reform; these changes to the documentation do not in and of themselves result in the discontinuation of hedge accounting or require the designation of a new hedge relationship. (1) Fair value hedges Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recorded in the income statement, together with the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk; this also applies if the hedged asset is classified as a financial asset at fair value through other comprehensive income. If the hedge no longer meets the criteria for hedge accounting, changes in the fair value of the hedged item attributable to the hedged risk are no longer recognised in the income statement. The cumulative adjustment that has been made to the carrying amount of the hedged item is amortised to the income statement using the effective interest method over the period to maturity. (2) Cash flow hedges The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognised in other comprehensive income in the cash flow hedging reserve. The gain or loss relating to the ineffective portion is recognised immediately in the income statement. Amounts accumulated in equity are reclassified to the income statement in the periods in which the hedged item affects profit or loss. When a hedging instrument expires or is sold, or when a hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss existing in equity at that time remains in equity and is recognised in the income statement when the forecast transaction is ultimately recognised in the income statement. When a forecast transaction is no longer expected to occur, the cumulative gain or loss that was reported in equity is immediately transferred to the income statement. (3) Net investment hedges Hedges of net investments in foreign operations are accounted for similarly to cash flow hedges. Any gain or loss on the hedging instrument relating to the effective portion of the hedge is recognised in other comprehensive income, the gain or loss relating to the ineffective portion is recognised immediately in the income statement. Gains and losses accumulated in equity are included in the income statement when the foreign operation is disposed of. The hedging instruments used in net investment hedges may include non-derivative liabilities as well as derivative financial instruments. (G) Offset Financial assets and liabilities are offset and the net amount reported in the balance sheet when there is a legally enforceable right of offset and there is an intention to settle on a net basis, or realise the asset and settle the liability simultaneously. Cash collateral on exchange traded derivative transactions is presented gross unless the collateral cash flows are always settled net with the derivative cash flows. In certain situations, even though master netting agreements exist, the lack of management intention to settle on a net basis results in the financial assets and liabilities being reported gross on the balance sheet. (H) Impairment of financial assets The impairment charge in the income statement reflects the change in expected credit losses, including those arising from fraud. Expected credit losses are recognised for loans and advances to customers and banks, other financial assets held at amortised cost, financial assets (other than equity investments) measured at fair value through other comprehensive income, and certain loan commitments and financial guarantee contracts. Expected credit losses are calculated as an unbiased and probability-weighted estimate using an appropriate probability of default, adjusted to take into account a range of possible future economic scenarios, and applying this to the estimated exposure of the Group at the point of default after taking into account the value of any collateral held, repayments, or other mitigants of loss and including the impact of discounting using the effective interest rate. At initial recognition, allowance (or provision in the case of some loan commitments and financial guarantees) is made for expected credit losses resulting from default events that are possible within the next 12 months (12-month expected credit losses). In the event of a significant increase in credit risk since origination, allowance (or provision) is made for expected credit losses resulting from all possible default events over the expected life of the financial instrument (lifetime expected credit losses). Financial assets where 12-month expected credit losses are recognised are considered to be Stage 1; financial assets which are considered to have experienced a significant increase in credit risk since initial recognition are in Stage 2; and financial assets which have defaulted or are otherwise considered to be credit-impaired are allocated to Stage 3. Some Stage 3 assets, mainly in Commercial Banking, are subject to individual rather than collective assessment. Such cases are subject to a risk-based impairment sanctioning process, and these are reviewed and updated at least quarterly, or more frequently if there is a significant change in the credit profile. The collective assessment of impairment aggregates financial instruments with similar risk characteristics, such as whether the facility is revolving in nature or secured and the type of security held against financial assets. An assessment of whether credit risk has increased significantly since initial recognition considers the change in the risk of default occurring over the remaining expected life of the financial instrument. In determining whether there has been a significant increase in credit risk, the Group uses quantitative tests based on relative and absolute probability of default (PD) movements linked to internal credit ratings together with qualitative indicators such as watchlists and other indicators of historical delinquency, credit weakness or financial difficulty. The use of internal credit ratings and qualitative indicators ensures alignment between the assessment of staging and the Group’s management of credit risk which utilises these internal metrics within distinct retail and commercial portfolio risk management practices. However, unless identified at an earlier stage, the credit risk of financial assets is deemed to have increased significantly when more than 30 days past due. The use of a payment holiday in and of itself has not been judged to indicate a significant increase in credit risk, with the underlying long-term credit risk deemed to be driven by economic conditions and captured through the use of forward-looking models. These portfolio-level models are capturing the anticipated volume of increased defaults and th

Disclosure of accounting judgements and estimates [Abstract]
CRITICAL ACCOUNTING JUDGEMENTS AND KEY SOURCES OF ESTIMATION UNCERTAINTY	NOTE 3: CRITICAL ACCOUNTING JUDGEMENTS AND KEY SOURCES OF ESTIMATION UNCERTAINTY The preparation of the Group’s financial statements in accordance with IFRS requires management to make judgements, estimates and assumptions in applying the accounting policies that affect the reported amounts of assets, liabilities, income and expenses. Due to the inherent uncertainty in making estimates, actual results reported in future periods may be based upon amounts which differ from those estimates. Estimates, judgements and assumptions are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. In preparing the financial statements, the Group has considered the impact of climate-related risks on its financial position and performance. While the effects of climate change represent a source of uncertainty, the Group does not consider there to be a material impact on its judgements and estimates from the physical, transition and other climate-related risks in the short term. The significant judgements, apart from those involving estimation, made by management in applying the Group’s accounting policies in these financial statements (critical judgements) and the key sources of estimation uncertainty that may have a significant risk of causing a material adjustment to the carrying amount of assets and liabilities within the next financial year (key sources of estimation uncertainty), which together are considered critical to the Group’s results and financial position, are as follows: Allowance for expected credit losses Critical judgements: Determining an appropriate definition of default against which a probability of default, exposure at default and loss given default parameter can be evaluated Establishing the criteria for a significant increase in credit risk (SICR) The use of management judgement alongside impairment modelling processes to adjust inputs, parameters and outputs to reflect risks not captured by models Key source of estimation uncertainty: Base case and multiple economic scenarios (MES) assumptions, including the rate of unemployment and the rate of change of house prices, required for creation of MES scenarios and forward-looking credit parameters The Group recognises an allowance for expected credit losses (ECLs) for loans and advances to customers and banks, other financial assets held at amortised cost, financial assets (other than equity investments) measured at fair value through other comprehensive income and certain loan commitment and financial guarantee contracts. At 31 December 2022, the Group’s expected credit loss allowance was £4,903 million (2021: £4,042 million), of which £4,580 million (2021: £3,842 million) was in respect of drawn balances . The calculation of the Group’s expected credit loss allowances and provisions against loan commitments and guarantees under IFRS 9 requires the Group to make a number of judgements, assumptions and estimates. Further information on the critical accounting judgements and key sources of estimation uncertainty (see above) and other significant judgements and estimates is set out in note 19. Valuation of assets and liabilities arising from insurance business Critical judgement: Future economic and operating conditions Key sources of estimation uncertainty: Future investment returns Future mortality rates Future expenses These judgements and estimates are subject to significant uncertainty. At 31 December 2022, the Group recognised a value of in-force business asset of £5,244 million (2021: £5,317 million) and an acquired value of in-force business asset of £175 million (2021: £197 million). The value of in-force business asset represents the estimated present value of future profits expected to arise from the portfolio of in-force life insurance and participating investment contracts. The valuation of this asset requires judgements to be made about future economic and operating conditions which are inherently uncertain and changes could significantly affect the value attributed to this asset. These judgements are used to determine appropriate assumptions for the asset’s valuation including the appropriate risk-free rate, retail price inflation and expense inflation. The methodology used to value this asset and the key assumptions that have been made in determining the carrying value of the value of in-force business asset at 31 December 2022 are set out in note 24. At 31 December 2022, the Group carried total liabilities arising from insurance contracts and participating investment contracts of £106,893 million (2021: £123,423 million). Elements of the valuations of liabilities arising from insurance contracts and participating investment contracts require management to estimate future investment returns, future mortality rates and future expenses. These estimates are subject to significant uncertainty. The methodology used to value these liabilities and the key assumptions that have been made in determining their carrying value are set out in note 31. The effect of changes to critical estimates used by management to determine the life insurance assets and liabilities is set out in note 32, which presents the impact of changes to the estimates made on the Group’s profit before tax and shareholders’ equity as management believes that this analysis best presents these sensitivities in a manner that helps the user of the financial statements to understand the judgements made by management and the level of estimation uncertainty. Defined benefit pension scheme obligations Critical judgement: Determination of an appropriate yield curve Key sources of estimation uncertainty: Discount rate applied to future cash flows Expected lifetime of the schemes’ members Expected rate of future inflationary increases The net asset recognised in the balance sheet at 31 December 2022 in respect of the Group’s defined benefit pension scheme obligations was £3,732 million comprising an asset of £3,823 million and a liability of £91 million (2021: a net asset of £4,404 million comprising an asset of £4,531 million and a liability of £127 million). The Group’s accounting policy for its defined benefit pension scheme obligations is set out in note 2(K). The accounting valuation of the Group’s defined benefit pension schemes’ liabilities requires management to make a number of assumptions. The key sources of estimation uncertainty are the discount rate applied to future cash flows, the expected lifetime of the schemes’ members and the expected rate of future inflationary increases. Income statement and balance sheet sensitivities to changes in the critical accounting estimates and other actuarial assumptions are provided in part (v) of note 35. Uncertain tax positions Critical judgement: Interpreting tax rules on the Group’s open tax matters The Group has an open matter in relation to a claim for group relief of losses incurred in its former Irish banking subsidiary, which ceased trading on 31 December 2010. In 2013, HMRC informed the Group that its interpretation of the UK rules means that the group relief is not available. In 2020, HMRC concluded their enquiry into the matter and issued a closure notice. The Group’s interpretation of the UK rules has not changed and hence it has appealed to the First Tier Tax Tribunal, with a hearing expected in 2023. If the final determination of the matter by the judicial process is that HMRC’s position is correct, management estimate that this would result in an increase in current tax liabilities of approximately £875 million (including interest) and a reduction in the Group’s deferred tax asset of approximately £295 million. The Group, having taken appropriate advice, does not consider that this is a case where additional tax will ultimately fall due. The Group makes other estimates in relation to tax which do not require significant judgements, see further discussion in note 36. Regulatory and legal provisions Critical judgements: Determining the scope of reviews required by regulators The impact of legal decisions that may be relevant to claims received Determining whether a reliable estimate is available for obligations arising from past events Key sources of estimation uncertainty: The number of future complaints The proportion of complaints that will be upheld The average cost of redress At 31 December 2022, the Group carried provisions of £803 million (2021: £1,156 million) against the cost of making redress payments to customers and the related administration costs in connection with historical regulatory breaches. Determining the amount of the provisions, which represent management’s best estimate of the cost of settling these issues, requires the exercise of significant judgement and estimation. It will often be necessary to form a view on matters which are inherently uncertain, such as the scope of reviews required by regulators, and to estimate the number of future complaints, the extent to which they will be upheld, the average cost of redress and the impact of decisions reached by legal and other review processes that may be relevant to claims received. Consequently the continued appropriateness of the underlying assumptions is reviewed on a regular basis against actual experience and other relevant evidence and adjustments made to the provisions where appropriate. Management has applied significant judgement in determining the provision required for HBOS Reading; further details are provided in note 37. Fair value of financial instruments Key source of estimation uncertainty: Interest rate spreads, earnings multiples and interest rate volatility At 31 December 2022, the carrying value of the Group’s financial instrument assets held at fair value was £228,516 million (2021: £256,959 million), and its financial instrument liabilities held at fair value was £84,772 million (2021: £86,223 million). The Group’s valuation control framework and a description of level 1, 2 and 3 financial assets and liabilities is set out in note 49(2). The valuation techniques for level 3 financial instruments involve management judgement and estimates, the extent of which depends on the complexity of the instrument and the availability of market observable information. In addition, in line with market practice, the Group applies credit, debit and funding valuation adjustments in determining the fair value of its uncollateralised derivative positions. A description of these adjustments is set out in note 49. A quantitative analysis of the sensitivities to market risk arising from the Group’s trading portfolios is set out in the tables marked audited on page 95 Capitalised software enhancements Critical judgement: Assessing future trading conditions that could affect the Group’s business operations Key source of estimation uncertainty: Estimated useful life of internally generated capitalised software At 31 December 2022, the carrying value of the Group’s capitalised software enhancements was £4,060 million (2021: £3,435 million). In determining the estimated useful life of capitalised software enhancements, management consider the product’s lifecycle and the Group’s technology strategy; assets are reviewed annually to assess whether there is any indication of impairment and to confirm that the remaining estimated useful life is still appropriate. For the year ended 31 December 2022, the amortisation charge was £833 million (2021: £892 million), and at 31 December 2022, the weighted-average remaining estimated useful life of the Group’s capitalised software enhancements was 4.5 years (2021: 4.7 years). If the Group reduced by one year the estimated useful life of those assets with a remaining estimated useful life of more than two years at 31 December 2022, the 2023 amortisation charge would be approximately £200 million higher. Consideration of climate change Financial statement preparation includes the consideration of the impact of climate change on the Group’s financial statements. There has been no material impact identified on the financial reporting judgement and estimates. In particular, the directors considered the impact of climate change in respect of the: • Going concern of the Group for a period of at least 12 months from the date of approval of the financial statements • Assessment of impairment of non-financial assets including goodwill • Carrying value and useful economic lives of property, plant and equipment • Fair value of financial assets and liabilities. These are generally based on market indicators which include the market’s assessment of climate risk • Economic scenarios used for measurement of expected credit losses and the behavioural lifetime of assets against the expected time horizons of when climate risks may materialise • Forecasting of the Group's future UK taxable profits, which impacts deferred tax recognition Whilst there is currently no material short-term impact of climate change expected, the Group acknowledges the long-term nature of climate risk and continues to monitor and assess climate risks highlighted in the risk management section on page 63 The following table demonstrates the effect of reasonably possible changes in key assumptions on profit before tax and equity disclosed in these financial statements assuming that the other assumptions remain unchanged. In practice this is unlikely to occur, and changes in some assumptions may be correlated. These amounts include movements in assets, liabilities and the value of the in-force business in respect of insurance contracts and participating investment contracts. The impact is shown in one direction but can be assumed to be reasonably symmetrical. 2022 2021 Change in variable Increase Increase Increase Increase Critical accounting estimates Annuitant mortality 1 5% reduction (188) (152) (301) (244) Future maintenance and investment expenses 2 10% reduction 309 250 355 288 Widening of credit default spreads 3 0.25% addition (284) (230) (433) (351) Increase in illiquidity premia 4 0.10% addition 114 92 190 154 Other accounting estimates Non-annuitant mortality and morbidity 5 5% reduction 22 18 13 11 Lapse rates 6 10% reduction 122 99 88 71 Risk-free rate 7 0.25% reduction 44 35 44 35 Guaranteed annuity option take up 8 5% addition (2) (2) (2) (2) Equity investment volatility 9 1% addition (2) (1) (2) (1) 1 This sensitivity shows the impact on the annuity and deferred annuity business of reducing mortality rates to 95 per cent of the expected rate. 2 This sensitivity shows the impact of reducing maintenance expenses and investment expenses to 90 per cent of the expected rate. 3 This sensitivity shows the impact of a 25 basis point increase in credit default spreads on corporate bonds and the corresponding reduction in market values. Swap curves, the risk-free rate and illiquidity premia are all assumed to be unchanged. 4 This sensitivity shows the impact of a 10 basis point increase in the allowance for illiquidity premia. It assumes the overall spreads on assets are unchanged and hence market values are unchanged. Swap curves and the non-annuity risk-free rate are both assumed to be unchanged. The increased illiquidity premium increases the annuity risk-free rate. 5 This sensitivity shows the impact of reducing mortality and morbidity rates on non-annuity business to 95 per cent of the expected rate. 6 This sensitivity shows the impact of reducing lapse and surrender rates to 90 per cent of the expected rate. 7 This sensitivity shows the impact on the value of in-force business, financial options and guarantee costs, statutory reserves and asset values of reducing the risk-free rate by 25 basis points. 8 This sensitivity shows the impact of a flat 5 per cent addition to the expected rate. 9 This sensitivity shows the impact of a flat 1 per cent addition to the expected rate.

Disclosure of entity's operating segments [Abstract]
SEGMENTAL ANALYSIS	NOTE 4: SEGMENTAL ANALYSIS Lloyds Banking Group provides a wide range of banking and financial services in the UK and in certain locations overseas. The Group Executive Committee (GEC) has been determined to be the chief operating decision-maker, as defined by IFRS 8 Operating Segments , for the Group. The Group’s operating segments reflect its organisational and management structures. The GEC reviews the Group’s internal reporting based around these segments in order to assess performance and allocate resources. They consider interest income and expense on a net basis and consequently the total interest income and expense for all reportable segments is presented net. The segments are differentiated by the type of products provided and by whether the customers are individuals or corporate entities. The segmental results and comparatives are presented on an underlying basis (pre-tax), the basis reviewed by the chief operating decision-maker. The underlying basis is derived from the recognition and measurement principles of IFRS with the effects of the following excluded in arriving at underlying profit before tax: • Restructuring costs relating to merger, acquisition and integration activities • Volatility and other items, which includes the effects of certain asset sales, the volatility relating to the Group’s hedging arrangements and that arising in the insurance businesses, the unwind of acquisition-related fair value adjustments and the amortisation of purchased intangible assets • Payment protection insurance remediation provisions, excluding litigation costs For the purposes of the underlying income statement, operating lease depreciation (net of gains on disposal of operating lease assets) is shown as an adjustment to total underlying income. During the year ended 31 December 2022, there were changes as a result of the Group restructure effective from 1 July 2022 and other methodology changes (comparatives have been restated accordingly): • Business Banking and Commercial Cards moved from Retail to Commercial Banking. Wealth moved from Insurance and Wealth to Retail. • Insurance and Wealth was renamed Insurance, Pensions and Investments. • The Group reviewed and updated its methodology for liquidity transfer pricing between segments. • The Group revised the treatment of restructuring costs and all such costs other than those relating to merger, acquisition and integration activities are now reported within operating costs in arriving at underlying profit. • Non lending-related fraud costs, previously included within underlying impairment, are now reported as part of operating costs (this has not impacted the statutory impairment charge). The Group's restructure created a revised organisational structure under its divisions. The Group completed a review and determined that it had three operating and reportable segments: Retail; Commercial Banking; and Insurance, Pensions and Investments: • Retail offers a broad range of financial services products to personal customers, including current accounts, savings, mortgages, credit cards, unsecured loans, motor finance and leasing solutions. • Commercial Banking serves small and medium businesses as well as corporate and institutional clients, providing lending, transactional banking, working capital management, debt financing and risk management services. • Insurance, Pensions and Investments offers insurance, investment and pension management products and services. Other comprises income and expenditure not attributed to the Group’s operating segments. These amounts include those arising from the Group’s equities business, residual net interest income after transfer pricing (including the central recovery of the Group’s distributions on other equity instruments) and certain gains from gilt sales. Inter-segment services are generally recharged at cost, although some attract a margin. In particular, a profit margin is charged on the internal commission arrangements between the branch network and other distribution channels and the insurance product manufacturing businesses within the Group. Inter-segment lending and deposits are generally entered into at market rates, except that non-interest bearing balances are priced at a rate that reflects the external yield that could be earned on such funds. For the majority of those derivative contracts entered into by business units for risk management purposes, the business unit recognises the net interest income or expense on an accrual accounting basis and transfers the remainder of the movement in the fair value of the derivative to the central function where the resulting accounting volatility is managed where possible through the establishment of hedge accounting relationships. Any change in fair value of the hedged instrument attributable to the hedged risk is also recorded within the central function. This allocation of the fair value of the derivative and change in fair value of the hedged instrument attributable to the hedged risk avoids accounting asymmetry in segmental results and leads to accounting volatility, which is managed centrally and reported within Other.

Fees and commissions relating to instruments that are held at fair value through profit or loss are included within net trading income shown in note 7. In determining the disaggregation of fees and commissions the Group has considered how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors, including those that are impacted by climate-related factors. It has determined that the above disaggregation by product type provides useful information that does not aggregate items that have substantially different characteristics and is not too detailed. At 31 December 2022, the Group held on its balance sheet £173 million (31 December 2021: £201 million) in respect of services provided to customers and £74 million (31 December 2021: £84 million) in respect of amounts received from customers for services to be provided after the balance sheet date. Current unsatisfied performance obligations amount to £149 million (31 December 2021: £157 million); the Group expects to receive substantially all of this revenue by 2024. Income recognised during the year included £8 million (2021: £16 million) in respect of amounts included in the contract liability balance at the start of the year and £1 million (2021: £2 million) in respect of amounts from performance obligations satisfied in previous years. The most significant performance obligations undertaken by the Group are in respect of current accounts, the provision of other banking services for commercial customers and credit and debit card services. In respect of current accounts, the Group receives fees for the provision of bank account and transaction services such as ATM services, fund transfers, overdraft facilities and other value-added offerings. For commercial customers, alongside its provision of current accounts, the Group provides other corporate banking services including factoring and commitments to provide loan financing. Loan commitment fees are included in fees and commissions where the loan is not expected to be drawn down by the customer. The Group receives interchange and merchant fees, together with fees for overseas use and cash advances, for provision of card services to cardholders and merchants.

Total non-audit services as defined by the FRC include all fees other than audit fees in respect of the statutory audit of Group entities. These fees totalled £12.8 million in 2022 (2021: £6.5 million; 2020: £5.1 million). The following types of services are included in the categories listed above: Audit fees: This category includes fees in respect of the audit of the Group’s annual financial statements (including work related to the adoption of new accounting standards) and other services in connection with regulatory filings. Other services supplied pursuant to legislation relate primarily to costs incurred in connection with client asset assurance and with the Sarbanes-Oxley Act requirements associated with the audit of the Group’s financial statements filed on its Form 20-F. Other audit-related fees: This category includes fees in respect of services for assurance and related services that are reasonably related to the performance of the audit or review of the financial statements, for example acting as reporting accountants in respect of debt prospectuses required by the Listing Rules. All other fees: This category includes other assurance services not related to the performance of the audit or review of the financial statements, for example, the review of controls operated by the Group on behalf of a third party. The auditors are not engaged to provide tax services. It is the Group’s policy to use the auditors only on assignments in cases where their knowledge of the Group means that it is neither efficient nor cost effective to employ another firm of accountants. The Group has procedures that are designed to ensure auditor independence, including prohibiting certain non-audit services. All audit and non-audit assignments must be pre-approved by the Audit Committee on an individual engagement basis; for certain types of non-audit engagements where the fee is ‘de minimis’ the Audit Committee has pre-approved all assignments subject to confirmation by management. On a quarterly basis, the Audit Committee receives and reviews a report detailing all pre-approved services and amounts paid to the auditors for such pre-approved services.

The Group’s impairment charge comprises the following items: Impact of transfers between stages The net impact on the impairment charge of transfers between stages. Other changes in credit quality Changes in loss allowance as a result of movements in risk parameters that reflect changes in customer quality, but which have not resulted in a transfer to a different stage. This also contains the impact on the impairment charge as a result of write-offs and recoveries, where the related loss allowances are reassessed to reflect ultimate realisable or recoverable value. Additions and repayments Expected loss allowances are recognised on origination of new loans or further drawdowns of existing facilities. Repayments relate to the reduction of loss allowances resulting from the repayments of outstanding balances that have been provided against. Methodology and model changes Increase or decrease in impairment charge as a result of adjustments to the models used for expected credit loss calculations; as changes to either the model inputs or the underlying assumptions, as well as the impact of changing the models used. Movements in the Group’s impairment allowances are shown in note 18.

This legislation, which is expected to be enacted in 2023, will seek to ensure that UK-headquartered multinational enterprises pay a minimum tax rate of 15 per cent on UK and overseas profits arising after 31 December 2023. As the UK rate of corporation tax in 2024 will be 25 per cent, and the Group’s business is primarily in the UK, the impact of these rules on the Group is not expected to be material.

For the calculation of diluted earnings per share the weighted-average number of ordinary shares in issue is adjusted to assume conversion of all dilutive potential ordinary shares that arise in respect of share options and awards granted to employees. The number of shares that could have been acquired at the annual average price of the Company’s shares based on the monetary value of the subscription rights attached to outstanding share options and awards is determined. This is deducted from the number of shares issuable under such options and awards to leave a residual bonus amount of shares which are added to the weighted-average number of ordinary shares in issue, but no adjustment is made to the profit attributable to equity shareholders. There were 63 million anti-dilutive share options and awards excluded from the calculation of diluted earnings per share (2021: 143 million; 2020: 647 million).

To reduce credit risk the Group uses a variety of credit enhancement techniques such as netting and collateralisation, where security is provided against the exposure; a large proportion of the Group’s derivatives are held through exchanges such as London Clearing House and are collateralised through those exchanges. Further details are provided in note 52 Credit risk. The Group holds derivatives as part of the following strategies: • Customer driven, where derivatives are held as part of the provision of risk management products to Group customers • To manage and hedge the Group’s interest rate and foreign exchange risk arising from normal banking business. The hedge accounting strategy adopted by the Group is to utilise a combination of fair value and cash flow hedge approaches as described in note 52 • Derivatives held in policyholder funds as permitted by the investment strategies of those funds The principal derivatives used by the Group are as follows: • Interest rate related contracts include interest rate swaps, forward rate agreements and options. An interest rate swap is an agreement between two parties to exchange fixed and floating interest payments, based upon interest rates defined in the contract, without the exchange of the underlying principal amounts. Forward rate agreements are contracts for the payment of the difference between a specified rate of interest and a reference rate, applied to a notional principal amount at a specific date in the future. An interest rate option gives the buyer, on payment of a premium, the right, but not the obligation, to fix the rate of interest on a future loan or deposit, for a specified period and commencing on a specified future date • Exchange rate related contracts include forward foreign exchange contracts, currency swaps and options. A forward foreign exchange contract is an agreement to buy or sell a specified amount of foreign currency on a specified future date at an agreed rate. Currency swaps generally involve the exchange of interest payment obligations denominated in different currencies; the exchange of principal can be notional or actual. A currency option gives the buyer, on payment of a premium, the right, but not the obligation, to sell specified amounts of currency at agreed rates of exchange on or before a specified future date • Credit derivatives, principally credit default swaps, are used by the Group as part of its trading activity and to manage its own exposure to credit risk. A credit default swap is a swap in which one counterparty receives a premium at pre-set intervals in consideration for guaranteeing to make a specific payment should a negative credit event take place • Equity derivatives are also used by the Group as part of its equity-based retail product activity to eliminate the Group’s exposure to fluctuations in various international stock exchange indices. Index-linked equity options are purchased which give the Group the right, but not the obligation, to buy or sell a specified amount of equities, or basket of equities, in the form of published indices on or before a specified future date Details of the Group’s hedging instruments are set out below: Maturity At 31 December 2022 Up to 1 month 1–3 months 3–12 months 1–5 years Over 5 years Total Fair value hedges Interest rate Cross currency swap Notional – – – – 35 35 Average fixed interest rate – – – – 1.28% Average EUR/GBP exchange rate – – – – 1.38 Interest rate swap Notional 1,904 12,765 37,488 64,307 36,198 152,662 Average fixed interest rate 1.51% 0.17% 0.72% 1.92% 1.94% Cash flow hedges Foreign exchange Currency swap Notional – – 509 1,004 29 1,542 Average EUR/GBP exchange rate – – 1.15 1.10 1.04 Average USD/GBP exchange rate – – 1.24 1.25 – Interest rate Interest rate swap Notional 4,741 6,472 26,175 161,391 50,924 249,703 Average fixed interest rate 3.01% 1.18% 2.36% 2.40% 1.60% Maturity At 31 December 2021 Up to 1 month 1–3 months 3–12 months 1–5 years Over 5 years Total Fair value hedges Interest rate Cross currency swap Notional – – – – 34 34 Average fixed interest rate – – – – 1.28% Average EUR/GBP exchange rate – – – – 1.38 Interest rate swap Notional 1,396 2,784 18,568 121,878 28,069 172,695 Average fixed interest rate 2.84% 1.31% 0.95% 0.68% 1.94% Cash flow hedges Foreign exchange Currency swap Notional 46 200 821 828 – 1,895 Average USD/GBP exchange rate 1.36 1.36 1.36 1.35 1.27 Interest rate Interest rate swap Notional 1,000 625 10,428 58,896 38,144 109,093 Average fixed interest rate 0.00% 0.23% 0.55% 0.81% 0.65% The carrying amounts of the Group’s hedging instruments are as follows: Carrying amount of the hedging instrument At 31 December 2022 Contract/ Assets Liabilities Changes in fair Fair value hedges Interest rate Currency swaps 35 1 – (2) Interest rate swaps 152,662 10 503 1,286 Cash flow hedges Foreign exchange Currency swaps 1,542 63 21 198 Interest rate Interest rate swaps 249,703 1 3 (6,990) Carrying amount of the hedging instrument At 31 December 2021 Contract/ Assets Liabilities Changes in fair Fair value hedges Interest rate Currency swaps 34 7 – (2) Interest rate swaps 172,695 46 308 946 Cash flow hedges Foreign exchange Currency swaps 1,895 27 18 (6) Interest rate Interest rate swaps 109,093 6 1 (2,642) All amounts are held within derivative financial instruments.

Transfers between stages are deemed to have taken place at the start of the reporting period, with all other movements shown in the stage in which the asset is held at 31 December, with the exception of those held within purchased or originated credit-impaired, which are not transferable. Additions and repayments comprise new loans originated and repayments of outstanding balances throughout the reporting period. Loans which are written off in the period are first transferred to Stage 3 before acquiring a full allowance and subsequent write-off.

Disclosure of allowance for expected credit losses [Abstract]
ALLOWANCE FOR EXPECTED CREDIT LOSSES	NOTE 19: ALLOWANCE FOR EXPECTED CREDIT LOSSES The calculation of the Group’s expected credit loss allowances and provisions against loan commitments and guarantees, which are set out in note 18, under IFRS 9 requires the Group to make a number of judgements, assumptions and estimates. The most significant are set out below: Definition of default The probability of default (PD) of an exposure, both over a 12-month period and over its lifetime, is a key input to the measurement of the ECL allowance. Default has occurred when there is evidence that the customer is experiencing significant financial difficulty which is likely to affect the ability to repay amounts due. The definition of default adopted by the Group is described in note 2(H) Impairment of financial assets. IFRS 9 contains a rebuttable presumption that default occurs no later than when a payment is 90 days past due which the Group now uses for all its products following changes to the definition of default for UK mortgages on 1 January 2022. In addition, other indicators of mortgage default were added including end-of-term payments on past due interest-only accounts and loans considered non-performing due to recent arrears or forbearance, aligning the definition of Stage 3 credit-impaired for IFRS 9 to the CRD IV prudential regulatory definition of default. This change in definition of default contributes to the £1.5 billion increase in Stage 3 UK mortgages during the period. Lifetime of an exposure A range of approaches, segmented by product type, has been adopted by the Group to estimate a product’s expected life. These include using the full contractual life and taking into account behavioural factors such as early repayments, extensions and refinancing. For non-revolving retail assets, the Group has assumed the expected life for each product to be the time taken for all significant losses to be observed. For revolving retail products, the Group has considered the losses beyond the contractual term over which the Group is exposed to credit risk. For commercial overdraft facilities, the average behavioural life has been used. Changes to the assumed expected lives of the Group’s assets could impact the ECL allowance recognised by the Group. The assessment of SICR and corresponding lifetime loss, and the PD, of a financial asset designated as Stage 2, or Stage 3, is dependent on its expected life. Significant increase in credit risk Performing assets are classified as either Stage 1 or Stage 2. An ECL allowance equivalent to 12 months’ expected losses is established against assets in Stage 1; assets classified as Stage 2 carry an ECL allowance equivalent to lifetime expected losses. Assets are transferred from Stage 1 to Stage 2 when there has been a significant increase in credit risk (SICR) since initial recognition. Credit-impaired assets are transferred to Stage 3 with a lifetime expected losses allowance. The Group uses both quantitative and qualitative indicators to determine whether there has been a SICR for an asset. For Retail, the following tables set out the retail master scale (RMS) grade triggers which result in a SICR for financial assets and the PD boundaries for each RMS grade. SICR triggers for key Retail portfolios Origination grade 1 2 3 4 5 6 7 Mortgages SICR grade 5 5 6 7 8 9 10 Credit cards, loans and overdrafts SICR grade 4 5 6 7 8 9 10 RMS grade 1 2 3 4 5 6 7 8 9 10 11 12 13 14 PD boundary % 1 0.10 0.40 0.80 1.20 2.50 4.50 7.50 10.00 14.00 20.00 30.00 45.00 99.99 100.00 1 Probability-weighted annualised lifetime probability of default. For Commercial a doubling of PD with a minimum increase in PD of 1 per cent and a resulting change in the underlying grade is treated as a SICR. The Group uses the internal credit risk classification and watchlist as qualitative indicators to identify a SICR. The Group does not use the low credit risk exemption in its staging assessments. The use of a payment holiday in and of itself has not been judged to indicate a significant increase in credit risk, nor forbearance, with the underlying long-term credit risk deemed to be driven by economic conditions and captured through the use of forward-looking models. These portfolio level models are capturing the anticipated volume of increased defaults and therefore an appropriate assessment of staging and expected credit loss. All financial assets are assumed to have suffered a SICR if they are more than 30 days past due; credit cards, loans and overdrafts financial assets are also assumed to have suffered a SICR if they are in arrears on three or more separate occasions in a rolling 12-month period. Financial assets are classified as credit-impaired if they are 90 days past due. A Stage 3 asset that is no longer credit-impaired is transferred back to Stage 2 as no cure period is applied to Stage 3. UK mortgages is an exception to this rule where a probation period is enforced for non-performing, forborne and defaulted exposures in accordance with prudential regulation. If an exposure that is classified as Stage 2 no longer meets the SICR criteria, which in some cases capture customer behaviour in previous periods, it is moved back to Stage 1. The setting of precise trigger points combined with risk indicators requires judgement. The use of different trigger points may have a material impact upon the size of the ECL allowance. The Group monitors the effectiveness of SICR criteria on an ongoing basis. Generation of multiple economic scenarios The estimate of expected credit losses is required to be based on an unbiased expectation of future economic scenarios. The approach used to generate the range of future economic scenarios depends on the methodology and judgements adopted. The Group’s approach is to start from a defined base case scenario, used for planning purposes, and to generate alternative economic scenarios around this base case. The base case scenario is a conditional forecast underpinned by a number of conditioning assumptions that reflect the Group’s best view of key future developments. If circumstances appear likely to materially deviate from the conditioning assumptions, then the base case scenario is updated. The base case scenario is central to a range of future economic scenarios generated by simulation of an economic model, for which the same conditioning assumptions apply as in the base case scenario. These scenarios are ranked by using estimated relationships with industry-wide historical loss data. With the base case already pre-defined, three other scenarios are identified as averages of constituent scenarios located around the 15th, 75th and 95th percentiles of the distribution. The full distribution is therefore summarised by a practical number of scenarios to run through ECL models representing an upside, the base case, and a downside scenario weighted at 30 per cent each, together with a severe downside scenario weighted at 10 per cent. The scenario weights represent the distribution of economic scenarios and not subjective views on likelihood. The inclusion of a severe downside scenario with a smaller weighting ensures that the non-linearity of losses in the tail of the distribution is adequately captured. Macroeconomic projections may employ reversionary techniques to adjust the paths of economic drivers towards long-run equilibria after a reasonable forecast horizon. The Group does not use such techniques to force the MES scenarios to revert to the base case planning view. Utilising such techniques would be expected to be immaterial for expected credit losses since loss sensitivity is highest over the initial five years of the projections. Most assets are expected to have matured, or reached the end of their behavioural life before the five-year horizon. A forum under the chairmanship of the Chief Economist meets at least quarterly to review and, if appropriate, recommend changes to the method by which economic scenarios are generated, for approval by the Chief Financial Officer and Chief Risk Officer. In June 2022, the Group judged it appropriate to include an adjusted severe downside scenario to incorporate a high CPI inflation and UK Bank Rate profiles and to adopt this adjusted severe downside scenario to calculate the Group's ECL. This is because the historic macroeconomic and loan loss data upon which the scenario model is calibrated imply an association of downside economic outcomes with easier monetary policy, and therefore low interest rates. The adjustment is considered to better reflect the risks around the Group’s base case view in an economic environment where supply shocks are the principal concern. The Group has continued to include a non-modelled severe downside scenario for Group ECL calculations for 31 December 2022 reporting. Base case and MES economic assumptions The Group’s base case economic scenario has been revised in light of the ongoing war in Ukraine, reversals in UK fiscal policy, and a continuing global shift towards a more restrictive monetary policy stance against a backdrop of elevated inflation pressures. The Group’s updated base case scenario has three conditioning assumptions: first, the war in Ukraine remains ‘local’, i.e. without overtly involving neighbouring countries, NATO or China; second, the UK labour market participation rate remains below pre-pandemic levels, impeding the economy’s supply capacity; and third, the Bank of England accommodates above-target inflation in the medium term, recognising the economic costs that might arise from a rapid return to the two per cent target. Based on these assumptions and incorporating the economic data published in the fourth quarter, the Group’s base case scenario is for a contraction in economic activity and a rise in the unemployment rate alongside declines in residential and commercial property prices, following increases in UK Bank Rate in response to persistent inflationary pressures. Risks around this base case economic view lie in both directions and are largely captured by the generation of alternative economic scenarios. The Group has accommodated the latest available information at the reporting date in defining its base case scenario and generating alternative economic scenarios. The scenarios include forecasts for key variables in the fourth quarter of 2022, for which actuals may have since emerged prior to publication. Scenarios by year The key UK economic assumptions made by the Group are shown in the following tables across a number of measures explained below. Annual assumptions Gross domestic product (GDP) and Consumer Price Index (CPI) inflation are presented as an annual change, house price growth and commercial real estate price growth are presented as the growth in the respective indices over each year. Unemployment rate and UK Bank Rate are averages over the year. Five-year average The five-year average reflects the average annual growth rate, or level, over the five-year period. It includes movements within the current reporting year, such that the position as of 31 December 2022 covers the five years 2022 to 2026. The inclusion of the reporting year within the five-year period reflects the need to predict variables which remain unpublished at the reporting date and recognises that credit models utilise both level and annual changes. The use of calendar years maintains a comparability between the annual assumptions presented. Five-year start to peak and trough The peak or trough for any metric may occur intra year and therefore not be identifiable from the annual assumptions, therefore they are also disclosed. For GDP, house price growth and commercial real estate price growth, the peak, or trough, reflects the highest, or lowest cumulative quarterly position reached relative to the start of the five-year period, which as of 31 December 2022 is 1 January 2022. Given these metrics may exhibit increases followed by greater falls, the start to trough movements quoted may be smaller than the equivalent ‘peak to trough’ movement (and vice versa for start to peak).

ECL sensitivity to economic assumptions The table below shows the Group’s ECL for the probability-weighted, upside, base case, downside and severe downside scenarios, with the severe downside scenario incorporating adjustments made to CPI inflation and UK Bank Rate paths. The stage allocation for an asset is based on the overall scenario probability-weighted PD and hence the staging of assets is constant across all the scenarios. In each economic scenario the ECL for individual assessments and post-model adjustments is typically held constant reflecting the basis on which they are evaluated. For 31 December 2022, however, post-model adjustments in Commercial Banking have been apportioned across the scenarios to better reflect the sensitivity of these adjustments to each scenario. Judgements applied through changes to model inputs are reflected in the scenario ECL sensitivities. The probability-weighted view shows the extent to which a higher ECL allowance has been recognised to take account of multiple economic scenarios relative to the base case; the uplift being £692 million compared to £223 million at 31 December 2021.

The table below shows the Group’s ECL for the upside, base case, downside and severe downside scenarios, with staging of assets based on each specific scenario probability of default. ECL applied through individual assessments and the majority of post-model adjustments are reported flat against each economic scenario, reflecting the basis on which they are evaluated. A probability-weighted scenario is not shown as this does not reflect the basis on which ECL is reported.

The impact of changes in the UK unemployment rate and House Price Index (HPI) have been assessed. Although such changes would not be observed in isolation, as economic indicators tend to be correlated in a coherent scenario, this gives insight into the sensitivity of the Group’s ECL to gradual changes in these two critical economic factors. The assessment has been made against the base case with the reported staging unchanged and is assessed through the direct impact on modelled ECL only, including management judgements applied through changes to model inputs. The change in univariate ECL sensitivity in the period is a result of the change in definition of default and associated model changes, and the deterioration in the base case on which the assessment has been performed. The table below shows the impact on the Group’s ECL resulting from a 1 percentage point (pp) increase or decrease in the UK unemployment rate. The increase or decrease is presented based on the adjustment phased evenly over the first ten quarters of the base case scenario. An immediate increase or decrease would drive a more material ECL impact as it would be fully reflected in both 12-month and lifetime PDs.

These assessments are carried out by the Business Support Unit based on detailed reviews and expected recovery strategies. While these assessments are based on the Group’s latest economic view, the use of Group-wide multiple economic scenarios and weightings is not considered appropriate for these cases due to their individual characteristics. In place of this, a range of case-specific outcomes are considered with any alternative better or worse outcomes that carry a 25 per cent likelihood taken into account in establishing a probability-weighted ECL. At 31 December 2022, individually assessed provisions for Commercial Banking were £1,008 million (2021: £905 million) which reflected a range of £908 million to £1,140 million (2021: £741 million to £1,024 million), based on the range of alternative outcomes considered. Application of judgement in adjustments to modelled ECL Impairment models fall within the Group’s model risk framework with model monitoring, periodic validation and back testing performed on model components (i.e. probability of default, exposure at default and loss given default). Limitations in the Group’s impairment models or data inputs may be identified through the ongoing assessment and validation of the output of the models. In these circumstances, management make appropriate adjustments to the Group’s allowance for impairment losses to ensure that the overall provision adequately reflects all material risks. These adjustments are determined by considering the particular attributes of exposures which have not been adequately captured by the impairment models and range from changes to model inputs and parameters, at account level, through to more qualitative post-model adjustments. Post-model adjustments are not typically calculated under each distinct economic scenario used to generate ECL, but on final modelled ECL. All adjustments are reviewed quarterly and are subject to internal review and challenge, including by the Audit Committee, to ensure that amounts are appropriately calculated and that there are specific release criteria identified. The coronavirus pandemic and the various support measures resulted in an economic environment which differed significantly from the historical economic conditions upon which the impairment models had been built. As a result there was a greater need for management judgements to be applied alongside the use of models at 31 December 2021. During 2022 the direct impact of the pandemic on both economic and credit performance has reduced, resulting in the release of all material judgements required specifically to capture COVID-19 risks. Conversely, the intensifying inflationary pressures alongside rising interest rates within the Group’s outlook have created further risks not deemed to be fully captured by ECL models. This has required judgements to be added to capture affordability risks from inflationary and rising interest rate pressures. At 31 December 2022 management judgement resulted in additional ECL allowances totalling £330 million (2021: £1,284 million). The table below analyses total ECL allowance by portfolio, separately identifying the amounts that have been modelled, those that have been individually assessed and those arising through the application of management judgement.

Judgements due to COVID-19 In 2021 the Group’s ECL allowance included amounts arising from the application of management judgement to address the impact of COVID-19. These adjustments principally comprised of: • UK mortgages: £52 million to allow for an increase in the time assumed between default and repossession as a result of the Group temporarily suspending the repossession of properties to support customers during the pandemic; • Credit Cards, Other Retail and Business Banking: £134 million in relation to adjustments made for government support and subdued levels of consumer spending which were judged to have contributed to the reduced flow of accounts into default and to improved average credit scores across portfolios; • Commercial Banking: £89 million in respect of adjustments to model inputs related to a reduction in the observed rate of UK corporate insolvencies. As anticipated, the rate of recoveries returned to pre-pandemic levels towards the end of 2021 and, with model outputs based on 12 months observed insolvency data, management believed the historically low levels of insolvencies seen during early 2021 did not reflect the underlying credit risk; • Commercial Banking: £80 million additional judgement in sectors which were considered to face an elevated risk due to COVID-driven restrictions, inflation and interest rate pressures; and • A £400 million adjustment in respect of the risk to the base case economic scenario conditioning assumptions The base case represents the Group’s most likely view, however management believed that in the context of the pandemic, the possibility that the conditioning assumptions were invalidated was firmly to the downside. In particular, the possibility that a future virus mutation had vaccine resistance leading to serious social and economic disruption. Such a possibility was outside of the Group’s methodology because it would invalidate one of the key assumptions behind the base case forecast. As such an adjustment was made to increase the Group's ECL allowances to reflect the increased downside risk and the potential for the severity of losses to stretch beyond the Group's severe scenario. As the adjustment was calculated centrally it was not allocated to specific portfolios. It was therefore allocated against Stage 1 assets given that the downside risks were largely considered to relate to non-defaulted exposures, the majority of which were in Stage 1. An indicative allocation to allow users to understand where the Group believed that the additional losses could arise was as follows: UK mortgages: c.£200 million, Credit cards and Other Retail: c. 100 million, Commercial Banking c.£100 million. Judgements due to inflationary risk UK mortgages: £49 million (2021: £52 million) These adjustments comprise: Inflationary and interest rate pressures: £49 million (2021: £52 million) There has been only modest evidence of credit deterioration in the UK mortgages portfolio through 2022 despite the high levels of inflation and the rising interest rate environment. Mortgage ECL models use bank base rate as a driver of predicted defaults and that has contributed to the elevated levels of ECL at 31

Disclosure of goodwill [Abstract]
GOODWILL	NOTE 23: GOODWILL 2022 £m 2021 £m At 1 January 2,320 2,320 Acquisition of businesses (see below) 335 – At 31 December 2,655 2,320 Cost 1 2,999 2,664 Accumulated impairment losses (344) (344) At 31 December 2,655 2,320 1 For acquisitions made prior to 1 January 2004, the date of transition to IFRS, cost is included net of amounts amortised up to 31 December 2003. On 31 January 2022, the Group completed the acquisition of 100 per cent of the share capital of Embark Group Limited (Embark), which together with its subsidiaries operates an investment and retirement platform business, enhancing the Group’s Wealth business capabilities, and has been consolidated into the Group’s results from that date. The total fair value of the purchase consideration was £377 million, settled in cash, and goodwill of £324 million has been recognised on the transaction. None of the goodwill recognised is deductible for tax purposes. Acquisition-related costs of £4 million have been included in operating expenses for the year ended 31 December 2022. The revenue included in the consolidated statement of comprehensive income since 31 January 2022 contributed by Embark was £81 million, with net loss after tax of £9 million over the same period. Had Embark been consolidated from 1 January 2022, the consolidated statement of comprehensive income would have included revenue of £87 million and a net loss after tax of £12 million. The goodwill relating to the acquisition of Embark has been allocated to the Group’s Life and pensions business as it is expected to benefit from the synergies of the acquisition. In addition, goodwill of £11 million arose on the Group’s acquisition of Cavendish Online during the year. The goodwill held in the Group’s balance sheet is tested at least annually for impairment. For the purposes of impairment testing the goodwill is allocated to the appropriate cash generating unit; of the total balance of £2,655 million (2021: £2,320 million), £2,171 million, or 82 per cent (2021: £1,836 million, 79 per cent), including the £324 million arising on the acquisition of Embark in the year, has been allocated to the Life and pensions cash generating unit; £302 million, or 11 per cent (2021: £302 million, 13 per cent) has been allocated to the Credit card cash generating unit in the Group’s Retail division; and £166 million, or 6 per cent (2021: £166 million, 7 per cent) to the Motor business cash generating unit. The recoverable amount of the goodwill relating to Scottish Widows is based on a value-in-use calculation. The calculation uses pre-tax projections of future cash flows based upon budgets and plans approved by management covering a four-year period, the related run-off of existing business in-force and a discount rate (pre-tax) of 11.2 per cent. The budgets and plans are based upon past experience adjusted to take into account anticipated changes in sales volumes, product mix and margins having regard to expected market conditions (which will reflect current and future risks, such as climate and expected economic activity conditions) and competitor activity. The discount rate is determined with reference to internal measures and available industry information. New business cash flows beyond the four-year period have been extrapolated using a reducing balance growth rate that falls from 3.5 per cent down to 2.0 percent after 20 years, which does not exceed the long-term average growth rate for the life assurance market. Management believes that any reasonably possible change in the key assumptions above would not cause the recoverable amount of the goodwill relating to Scottish Widows to fall below its balance sheet carrying value. The recoverable amount of the goodwill relating to the Motor business is based on a value-in-use calculation using post-tax cash flow projections based on financial budgets and plans approved by management covering a four-year period and a discount rate (post-tax) of 10 per cent, based on the Group’s cost of equity. The cash flows beyond the four-year period are extrapolated using a growth rate of 3.5 per cent which does not exceed the long-term average growth rates for the markets in which the Motor business participates. Management believes that any reasonably possible change in the key assumptions, including from the impacts of climate change or climate-related legislation, would not cause the recoverable amount of the goodwill relating to the Motor business to fall below the balance sheet carrying value. The recoverable amount of the goodwill relating to Credit cards has been based on a value-in-use calculation using post-tax cash flow projections based on financial budgets and plans approved by management covering a four-year period and a discount rate (post-tax) of 10 per cent, based on the Group’s cost of equity. The cash flows beyond the four-year period assume 3.5 per cent growth. Management believes that any reasonably possible change in the key assumptions above would not cause the recoverable amount of the goodwill relating to Credit cards to fall below the balance sheet carrying value.

Disclosure of value of in-force business [Abstract]
VALUE OF IN-FORCE BUSINESS	NOTE 24: VALUE OF IN-FORCE BUSINESS Key assumptions The impacts of reasonably possible changes in the key assumptions made in respect of the Group’s life insurance business, which include the impact on the value of in-force business, are disclosed in note 32. The principal features of the methodology and process used for determining key assumptions used in the calculation of the value of in-force business are set out below: Economic assumptions Each cash flow is valued using the discount rate consistent with that applied to such a cash flow in the capital markets. In practice, to achieve the same result, where the cash flows are either independent of or move linearly with market movements, a method has been applied known as the ‘certainty equivalent’ approach whereby it is assumed that all assets earn a risk-free rate and all cash flows are discounted at a risk-free rate. The certainty equivalent approach covers all investment assets relating to insurance and participating investment contracts, other than the annuity business (where an illiquidity premium is included, see below). A market-consistent approach has been adopted for the valuation of financial options and guarantees, using a stochastic option pricing technique calibrated to be consistent with the market price of relevant options at each valuation date. Further information on options and guarantees can be found in note 31. The liabilities in respect of the Group’s UK annuity business are matched by a portfolio of fixed interest securities, including a large proportion of corporate bonds and illiquid loan assets. The value of the in-force business asset for UK annuity business has been calculated after taking into account an estimate of the market premium for illiquidity in respect of corporate bond holdings and relevant illiquid loan assets. In determining the market premium for illiquidity, a range of inputs are considered which reflect actual asset allocation and relevant observable market data. The illiquidity premium is estimated to be 160 basis points at 31 December 2022 (31 December 2021: 88 basis points). The risk-free rate is derived from the relevant swap curve with a deduction for credit risk. The table below shows the resulting range of yields and other key assumptions at 31 December: 2022 % 2021 % Risk-free rate (value of in-force non-annuity business) 1 1.94 to 4.55 (0.16) to 3.60 Risk-free rate (value of in-force annuity business) 1 3.54 to 6.15 0.72 to 4.49 Risk-free rate (financial options and guarantees) 1 1.94 to 4.55 (0.16) to 3.60 Retail price inflation 3.70 3.28 Expense inflation 4.00 3.58 1 All risk-free rates are quoted as the range of rates implied by the relevant forward swap curve. Non-market risk An allowance for non-market risk is made through the choice of best estimate assumptions based upon experience, which generally will give the mean expected financial outcome for shareholders and hence no further allowance for non-market risk is required. However, in the case of operational risk, reinsurer default and the with-profit funds these can be asymmetric in the range of potential outcomes for which an explicit allowance is made. Non-economic assumptions Future mortality, morbidity, expenses, lapse and paid-up rate assumptions are reviewed each year and are based on an analysis of past experience and on management’s view of future experience. Further information on these assumptions is given in note 31 and the effect of changes in key assumptions is given in note 32. The value of in-force business asset in the consolidated balance sheet is comprised as follows: 2022 £m 2021 £m Acquired value of in-force non-participating investment contracts 175 197 Value of in-force insurance and participating investment contracts 5,244 5,317 Total value of in-force business 5,419 5,514 The movement in the acquired value of in-force non-participating investment contracts over the year is as follows: 2022 £m 2021 £m At 1 January 197 221 Amortisation (note 11) (22) (24) At 31 December 175 197 The acquired value of in-force non-participating investment contracts includes £106 million (2021: £119 million) in relation to OEIC business.

This will also contain changes in the other assets and liabilities of the relevant businesses, including the effects of changes in assumptions used to value the liabilities. The presentation of economic variance includes the impact of financial market conditions being different at the end of the year from those included in assumptions used to calculate new and existing business returns.

The carrying value at 31 December 2022 was £380 million (2021: £380 million). The Bank of Scotland name has been in existence for over 300 years and there are no indications that the brand should not have an indefinite useful life. The recoverable amount has been based on a value-in-use calculation. The calculation uses post-tax projections for a four-year period of the income generated by the Bank of Scotland cost generating unit, a discount rate of 10 per cent and a future growth rate of 3.5 per cent. Management believes that any reasonably possible change in the key assumptions would not cause the recoverable amount of the Bank of Scotland brand to fall below its balance sheet carrying value.

They are valued by external Chartered Surveyors using industry standard techniques based on guidance from the Royal Institute of Chartered Surveyors. The valuation methodology includes an assessment of general market conditions and sector level transactions and takes account of expectations of occupancy rates, rental income and growth. Property valuations undergo individual scrutiny using cash flow analysis to factor in the timing of rental reviews, capital expenditure, lease incentives, dilapidation and operating expenses; these reviews utilise both observable and unobservable inputs. Within the fair value hierarchy, all of the Group’s investment properties are categorised as level 3 (see note 49 for details of levels in the fair value hierarchy). The table below analyses movements in level 3 investment properties, which are carried at fair value. 2022 £m 2021 £m At 1 January 3,612 3,347 Acquisition of new properties 60 18 Additional expenditure on existing properties 50 68 Change in fair value (note 7) (511) 575 Disposals (679) (396) At 31 December 2,532 3,612 Rental income of £145 million (2021: £186 million) and direct operating expenses of £32 million (2021: £25 million) arising from investment properties that generate rental income have been recognised in the income statement.

The amount contractually payable on maturity of the debt securities held at fair value through profit or loss at 31 December 2022 was £11,195 million, which was £6,036 million higher than the balance sheet carrying value (2021: £10,558 million, which was £4,021 million higher than the balance sheet carrying value). At 31 December 2022 there was a cumulative £324 million decrease in the fair value of these liabilities attributable to changes in credit spread risk; this is determined by reference to the quoted credit spreads of Lloyds Bank plc, the issuing entity within the Group. Of the cumulative amount, a decrease of £519 million arose in 2022 and an increase of £86 million arose in 2021. For the fair value of collateral pledged in respect of repurchase agreements see note 52. In addition to the liabilities above, the Group’s non-participating investment contracts (see note 33) are held at fair value through profit or loss.

SECURITISATIONS AND COVERED BONDS	NOTE 30: SECURITISATIONS AND COVERED BONDS Securitisation programmes Loans and advances to customers include loans securitised under the Group’s securitisation programmes, the majority of which have been sold by subsidiary companies to bankruptcy remote structured entities. As the structured entities are funded by the issue of debt on terms whereby the majority of the risks and rewards of the portfolio are retained by the subsidiary, the structured entities are consolidated fully and all of these loans are retained on the Group’s balance sheet, with the related notes in issue included within debt securities in issue. Covered bond programmes Certain loans and advances to customers have been assigned to bankruptcy remote limited liability partnerships to provide security for issues of covered bonds by the Group. The Group retains all of the risks and rewards associated with these loans and the partnerships are consolidated fully with the loans retained on the Group’s balance sheet and the related covered bonds in issue included within debt securities in issue. The Group’s principal securitisation and covered bond programmes, together with the balances of the advances subject to these arrangements and the carrying value of the externally held notes in issue at 31 December, are listed below.

Cash deposits of £3,896 million (2021: £3,558 million) which support the debt securities issued by the structured entities, the term advances related to covered bonds and other legal obligations, are held by the Group. Additionally, the Group has certain contractual arrangements to provide liquidity facilities to some of these structured entities. At 31 December 2022 these obligations had not been triggered; the maximum exposure under these facilities was £25 million (2021: £52 million). The Group has two covered bond programmes, for which limited liability partnerships have been established to ring-fence asset pools and guarantee the covered bonds issued by the Group. At the reporting date the Group had over-collateralised these programmes as set out in the table above to meet the terms of the programmes, to secure the rating of the covered bonds and to provide operational flexibility. From time to time, the obligations of the Group to provide collateral may increase due to the formal requirements of the programmes. The Group may also voluntarily contribute collateral to support the ratings of the covered bonds. The Group recognises the full liabilities associated with its securitisation and covered bond programmes within debt securities in issue, although the obligations of the Group in respect of its securitisation issuances are limited to the cash flows generated from the underlying assets. The Group could be required to provide additional support to a number of the securitisation programmes to support the credit ratings of the debt securities issued, in the form of increased cash reserves and the holding of subordinated notes. Further, certain programmes contain contractual obligations that require the Group to repurchase assets should they become credit-impaired or as otherwise required by the transaction documents. The Group has not provided financial or other support by voluntarily offering to repurchase assets from any of its public securitisation programmes during 2022 (2021: none).

The primary purpose of the conventional and unitised business written in the with-profit funds is to provide a smoothed investment vehicle to policyholders, protecting them against short-term market fluctuations. Pay-outs may be subject to a guaranteed minimum pay-out if certain policy conditions are met. With-profit policyholders are entitled to at least 90 per cent of the distributed profits, with the shareholders receiving the balance. The policyholders are also usually insured against death and the policy may carry a guaranteed annuity option at retirement. (ii) Method of calculation of liabilities With-profit liabilities are stated at their realistic value, the main components of which are: • With-profit benefit reserve, the total asset shares for with-profit policies • Cost of options and guarantees (including guaranteed annuity options) • Deductions levied against asset shares • Planned enhancements to with-profit benefit reserve • Impact of the smoothing policy (iii) Assumptions Key assumptions used in the calculation of with-profit liabilities, which reflect the impacts of COVID-19 that has also increased the level of uncertainty (in particular in relation to persistency and mortality assumptions) and the processes for determining these, are: Investment returns and discount rates With-profit fund liabilities are valued on a market-consistent basis, achieved by the use of a valuation model which values liabilities on a basis calibrated to tradable market option contracts and other observable market data. The with-profit fund financial options and guarantees are valued using a stochastic simulation model where all assets are assumed to earn, on average, the risk-free yield and all cash flows are discounted using the risk-free yield. The risk-free yield is defined as the spot yield derived from the relevant swap curve, adjusted for credit risk. Further information on significant options and guarantees is given below. Guaranteed annuity option take-up rates Certain pension contracts contain guaranteed annuity options that allow the policyholder to take an annuity benefit on retirement at annuity rates that were guaranteed at the outset of the contract. For contracts that contain such options, key assumptions in determining the cost of options are economic conditions in which the option has value, mortality rates and take-up rates of other options. The financial impact is dependent on the value of corresponding investments, interest rates and longevity at the time of the claim. Investment volatility The calibration of the stochastic simulation model uses implied volatilities of derivatives where possible, or historical volatility where it is not possible to observe meaningful prices. Mortality The mortality assumptions for the main classes of business are set with regard to recent Group experience and general industry trends, all of which are adjusted for smoker status and age/gender specific factors. The mortality tables used in the valuation are summarised below: 2022 2021 Annuities 94% Bespoke tables 94% Bespoke tables Whole of life assurance Bespoke tables Bespoke tables Term assurance 88%–111% of TxxL08 tables 88%–111% of TxxL08 tables Pensions 64%–77% of TxxL08 tables 64%–77% of TxxL08 tables Savings 62%–74% of AxC00 tables 55%–80% of AxC00 tables Lapse rates (persistency) Lapse rates refer to the rate of policy termination or the rate at which policyholders stop paying regular premiums due under the contract. Historical persistency experience is analysed using statistical techniques. As experience can vary considerably between different product types and for contracts that have been in force for different periods, the data is broken down into broadly homogenous groups for the purposes of this analysis. The most recent experience is considered along with the results of previous analyses and management’s views on future experience, taking into consideration potential changes in future experience that may result from guarantees and options becoming more valuable under adverse market conditions, in order to determine a ‘best estimate’ view of what persistency will be. In determining this best estimate view a number of factors are considered, including the credibility of the results (which will be affected by the volume of data available), any exceptional events that have occurred during the period under consideration, any known or expected trends in underlying data and relevant published market data. (iv) Options and guarantees within the With-Profit Funds The most significant options and guarantees provided from within the With-Profit Funds are in respect of guaranteed minimum cash benefits on death, maturity, retirement or certain policy anniversaries, and guaranteed annuity options on retirement for certain pension policies. For those policies written in Scottish Widows pre-demutualisation containing potentially valuable options and guarantees, under the terms of the demutualisation scheme a separate memorandum account was set up, within the With-Profit Fund originally held in Scottish Widows plc and subsequently transferred into Scottish Widows Limited, called the Additional Account, which is available, inter alia, to meet any additional costs of providing guaranteed benefits in respect of those policies. The Additional Account had a value at 31 December 2022 of £1.9 billion (2021: £2.5 billion). The eventual cost of providing benefits on policies written both pre and post demutualisation is dependent upon a large number of variables, including future interest rates and equity values, demographic factors, such as mortality, and the proportion of policyholders who seek to exercise their options. The ultimate cost will therefore not be known for many years. As noted above, the liabilities of the With-Profit Funds are valued using a market-consistent stochastic simulation model which places a value on the options and guarantees capturing both their intrinsic value and time value. The most significant economic assumptions included in the model are risk-free yield and investment volatility. Non-profit fund liabilities (i) Business description The Group principally writes the following types of life insurance contracts within its non-profit funds. Shareholder profits on these types of business arise from management fees and other policy charges. Unit-linked business This includes unit-linked pensions and unit-linked bonds, the primary purpose of which is to provide an investment vehicle where the policyholder is also insured against death. Life insurance The policyholder is insured against death or permanent disability, usually for predetermined amounts. Such business includes whole of life and term assurance and long-term creditor policies. Annuities The policyholder is entitled to payments for the duration of their life and is therefore insured against surviving longer than expected. (ii) Method of calculation of liabilities The non-profit fund liabilities are determined on the basis of recognised actuarial methods and involve estimating future policy cash flows over the duration of the in-force book of policies, and discounting the cash flows back to the valuation date allowing for probabilities of occurrence. (iii) Assumptions Generally, assumptions used to value non-profit fund liabilities are prudent in nature and therefore contain a margin for adverse deviation. This margin for adverse deviation is based on management’s judgement and reflects management’s views on the inherent level of uncertainty. In calculating the value of non-profit fund liabilities, the impacts of COVID-19, which have increased the level of uncertainty, have been considered, in particular in relation to persistency and mortality. The key assumptions used in the measurement of non-profit fund liabilities are: Interest rates The rates of interest used are determined by reference to a number of factors including the redemption yields on fixed interest assets at the valuation date. Margins for risk are allowed for in the assumed interest rates, including reductions made to the available yields to allow for default risk based upon the credit rating of the securities allocated to the insurance liability. Mortality and morbidity The mortality assumptions for the main classes of business are as follows: 2022 2021 Annuities 94% Bespoke tables 94% Bespoke tables Whole of life assurance Bespoke tables Bespoke tables Term assurance 88%–111% of TxxL08 tables 88%–111% of TxxL08 tables Pensions 64%–77% of TxxL08 tables 64%–77% of TxxL08 tables Savings 62%–74% of AxC00 tables 55%–80% of AxC00 tables Lapse rates (persistency) Lapse rates are allowed for on some non-profit fund contracts. The process for setting these rates is as described for with-profit liabilities, however a prudent scenario is assumed by the inclusion of a margin for adverse deviation within the non-profit fund liabilities. Maintenance expenses Allowance is made for future policy costs explicitly. Expenses are determined by reference to an internal analysis of current and expected future costs plus a margin for adverse deviation. Explicit allowance is made for future expense inflation. Key changes in assumptions A detailed review of the Group’s demographic and expense assumptions in 2022 resulted in a net gain of £348 million (2021 : net gain of £43 million). The following were the key impacts on profit before tax: • Change in persistency assumptions (£229 million increase (2021: £15 million decrease)) • Change in the assumption in respect of current and future mortality and morbidity rates (£112 million increase (2021: £149 million increase)) • Change in expense assumptions (£9 million increase (2021: £94 million decrease)) These amounts include the impacts of movements in liabilities and value of the in-force business in respect of insurance contracts and participating investment contracts. (iv) Options and guarantees outside the With-Profit Funds A number of typical guarantees are provided outside the With-Profit Funds such as guaranteed payments on death (for example term assurance) or guaranteed income for life (for example annuities). Caps and floors on inflation-linked increases to benefits and premiums across the annuities and protection business form additional guarantees within the Group’s insurance business. Key assumptions affecting the time value of these guarantees are inflation, inflation volatility and interest rates. At 31 December 2022, additional reserves of £74 million were held to cover the time value of these guarantees. In addition, certain personal pension policyholders in Scottish Widows, for whom reinstatement to their occupational pension scheme was not an option, have been given a guarantee that their pension and other benefits will correspond in value to the benefits of the relevant occupational pension scheme. The key assumptions affecting the ultimate value of the guarantee are future salary growth, gilt yields at retirement, annuitant mortality at retirement, marital status at retirement and future investment returns. There is currently a provision, calculated on a deterministic basis, of £30 million (2021: £61 million) in respect of those guarantees. (2) Non-life insurance For non-life insurance contracts, the methodology and assumptions used in relation to determining the bases of the earned premium and claims provisioning levels are derived for each individual underwritten product. Assumptions represent the Group’s estimates of the most likely or expected outcome, with a margin added for uncertainty reserves. There has been no significant change in the assumptions and methodologies used for setting reserves. The movements in non-life insurance contract liabilities and reinsurance assets over the year have been as follows: 2022 £m 2021 £m Provisions for unearned premiums Gross provision at 1 January 312 330 Increase in the year 494 624 Release in the year (560) (642) Change in provision for unearned premiums charged (credited) to income statement (66) (18) Gross provision at 31 December 246 312 Reinsurers’ share (17) (16) Net provision at 31 December 229 296 These provisions represent the liability for short-term insurance contracts for which the Group’s obligations are not expired at the year end. 2022 £m 2021 £m Claims outstanding Gross claims outstanding at 1 January 288 265 Cash paid for claims settled in the year (342) (305) Increase in liabilities charged to the income statement 1 415 328 73 23 Gross claims outstanding at 31 December 361 288 Reinsurers’ share (2) – Net claims outstanding at 31 December 359 288 Notified claims 208 177 Incurred but not reported 151 111 Net claims outstanding at 31 December 359 288 1 Of which an increase of £402 million (2021: increase of £367 million) was in respect of current year claims and an increase of £13 million (2021: decrease of £39 million) was in respect of prior year claims. These claims liabilities are not discounted because they are typically settled within three years.

LIFE INSURANCE SENSITIVITY ANALYSIS	NOTE 32: LIFE INSURANCE SENSITIVITY ANALYSIS The following table demonstrates the effect of reasonably possible changes in key assumptions on profit before tax and equity disclosed in these financial statements assuming that the other assumptions remain unchanged. In practice this is unlikely to occur, and changes in some assumptions may be correlated. These amounts include movements in assets, liabilities and the value of the in-force business in respect of insurance contracts and participating investment contracts. The impact is shown in one direction but can be assumed to be reasonably symmetrical. 2022 2021 Change in variable Increase Increase Increase Increase Critical accounting estimates Annuitant mortality 1 5% reduction (188) (152) (301) (244) Future maintenance and investment expenses 2 10% reduction 309 250 355 288 Widening of credit default spreads 3 0.25% addition (284) (230) (433) (351) Increase in illiquidity premia 4 0.10% addition 114 92 190 154 Other accounting estimates Non-annuitant mortality and morbidity 5 5% reduction 22 18 13 11 Lapse rates 6 10% reduction 122 99 88 71 Risk-free rate 7 0.25% reduction 44 35 44 35 Guaranteed annuity option take up 8 5% addition (2) (2) (2) (2) Equity investment volatility 9 1% addition (2) (1) (2) (1) 1 This sensitivity shows the impact on the annuity and deferred annuity business of reducing mortality rates to 95 per cent of the expected rate. 2 This sensitivity shows the impact of reducing maintenance expenses and investment expenses to 90 per cent of the expected rate. 3 This sensitivity shows the impact of a 25 basis point increase in credit default spreads on corporate bonds and the corresponding reduction in market values. Swap curves, the risk-free rate and illiquidity premia are all assumed to be unchanged. 4 This sensitivity shows the impact of a 10 basis point increase in the allowance for illiquidity premia. It assumes the overall spreads on assets are unchanged and hence market values are unchanged. Swap curves and the non-annuity risk-free rate are both assumed to be unchanged. The increased illiquidity premium increases the annuity risk-free rate. 5 This sensitivity shows the impact of reducing mortality and morbidity rates on non-annuity business to 95 per cent of the expected rate. 6 This sensitivity shows the impact of reducing lapse and surrender rates to 90 per cent of the expected rate. 7 This sensitivity shows the impact on the value of in-force business, financial options and guarantee costs, statutory reserves and asset values of reducing the risk-free rate by 25 basis points. 8 This sensitivity shows the impact of a flat 5 per cent addition to the expected rate. 9 This sensitivity shows the impact of a flat 1 per cent addition to the expected rate. Assumptions have been flexed on the basis used to calculate the value of in-force business and the realistic and statutory reserving bases.

All significant schemes are based in the UK, with the three most significant being the main sections of the Lloyds Bank Pension Scheme No. 1, the Lloyds Bank Pension Scheme No. 2 and the HBOS Final Salary Pension Scheme. At 31 December 2022, these schemes represented 94 per cent of the Group’s total gross defined benefit pension assets (2021: 94 per cent). These schemes provide retirement benefits calculated as a proportion of final pensionable salary depending upon the length of pensionable service; the minimum retirement age under the rules of the schemes at 31 December 2022 is generally 55, although certain categories of member are deemed to have a protected right to retire at 50. The Group operates both funded and unfunded pension arrangements; the majority, including the three most significant schemes, are funded schemes in the UK. All of these UK funded schemes are operated as separate legal entities under trust law, are in compliance with the Pensions Act 2004 and are managed by a Trustee Board (the Trustee) whose role is to ensure that their scheme is administered in accordance with the scheme rules and relevant legislation, and to safeguard the assets in the best interests of all members and beneficiaries. The Trustee is solely responsible for setting investment policy and for agreeing funding requirements with the employer through the funding valuation process. The Board of Trustees must be composed of representatives of the scheme membership along with a combination of independent and employer appointed trustees to comply with legislation and scheme rules. A valuation to determine the funding status of each scheme is carried out at least every three years, whereby scheme assets are measured at market value and liabilities (technical provisions) are measured using prudent assumptions. If a deficit is identified a recovery plan is agreed between the employer and the scheme Trustee and sent to the Pensions Regulator for review. The Group has not provided for these deficit contributions as the future economic benefits arising from these contributions are expected to be available to the Group. The Group’s overseas defined benefit pension schemes are subject to local regulatory arrangements. The most recent triennial funding valuations of the Group’s three main defined benefit pension schemes showed an aggregate ongoing funding deficit of £7.3 billion as at 31 December 2019 (a funding level of 85.7 per cent). Under the agreed recovery plan, £0.8 billion plus a further 30 per cent of in-year capital distributions to ordinary shareholders, up to a limit on total deficit contributions of £2.0 billion per annum, is payable until the 2019 deficit has been removed. These schemes continue to have a funding deficit, but are in a significantly stronger financial position than at 31 December 2021, when the deficit was c.£4.0 billion. During 2022, deficit contributions of £2.2 billion were paid into these schemes and the Group expects to make a further fixed contribution of £0.8 billion in the first half of 2023, consistent with 2021 and 2022. The Group expects to have substantially agreed the triennial valuation with the Trustee by the end of the third quarter of 2023, along with a revised contribution schedule in respect of any remaining deficit. Trustee agreement will be conditional upon prior feedback from the Pensions Regulator. The Group also expects that future contributions will become increasingly contingent in nature, such that they are only paid into the schemes if required. The deficit contributions are in addition to the regular contributions to meet benefits accruing over the year, and to cover the expenses of running the schemes. The Group expects to pay contributions of at least £1.1 billion to its defined benefit schemes in 2023. During 2009, the Group made one-off contributions to the Lloyds Bank Pension Scheme No. 1 and Lloyds Bank Pension Scheme No. 2 in the form of interests in limited liability partnerships for each of the two schemes which hold assets to provide security for the Group’s obligations to the two schemes. At 31 December 2022, the limited liability partnerships held assets of £6.3 billion. The limited liability partnerships are consolidated fully in the Group’s balance sheet. The Group has also established three private limited companies which hold assets to provide security for the Group’s obligations to the HBOS Final Salary Pension Scheme, a section of the Lloyds Bank Pension Scheme No. 1 and the Lloyds Bank Offshore Pension Scheme. At 31 December 2022 these held assets of £4.5 billion in aggregate. The private limited companies are consolidated fully in the Group’s balance sheet. The terms of these arrangements require the Group to maintain assets in these vehicles to agreed minimum values in order to secure obligations owed to the relevant Group pension schemes. The Group has satisfied this requirement during 2022. The last funding valuations of other Group schemes were carried out on a number of different dates. In order to report the position under IAS 19 as at 31 December 2022, the most recent valuation results for all schemes have been updated by qualified independent actuaries. The funding valuations use a more prudent approach to setting the discount rate and more conservative longevity and inflation assumptions than the IAS 19 valuations. In a judgment in 2018, the High Court confirmed the requirement to equalise the Guaranteed Minimum Pension (GMP) benefits of men and women accruing between 1990 and 1997 from contracting out of the State Earnings Related Pension Scheme. The Group recognised a past service cost of £108 million in respect of equalisation in 2018 and, following agreement of the detailed implementation approach with the Trustee, a further £33 million was recognised in 2019. A further hearing was held during 2020 which confirmed the extent of the Trustee’s obligation to revisit past transfers out of the schemes. The amount of any additional liability as a result of this judgment is still being reviewed but is not considered likely to be material.

This policy is reviewed annually (or more frequently as required) and has been shared with the schemes’ investment managers for implementation. Climate change is one of the risks the schemes manage given its potential financial impact on valuation of assets. (iv) Assumptions The principal actuarial and financial assumptions used in valuations of the defined benefit pension schemes were as follows: 2022 % 2021 % Discount rate 4.93 1.94 Rate of inflation: Retail Price Index (RPI) 3.13 3.21 Consumer Price Index (CPI) 2.69 2.92 Rate of salary increases 0.00 0.00 Weighted-average rate of increase for pensions in payment 2.84 2.88 On 25 November 2020 the Chancellor of the Exchequer announced the outcome of a consultation into a reform of the calculation of RPI. It is now expected that from 2030 RPI will be aligned with CPIH (the Consumer Price Index including owner occupiers’ housing costs). To determine the RPI assumption a term-dependent inflation curve has been used adjusting for an assumed inflation risk premium. In the period to 2030 a gap of 100 basis points has been assumed between RPI and CPI; thereafter a 10 basis point gap has been assumed. Men Women 2022 Years 2021 Years 2022 Years 2021 Years Life expectancy for member aged 60, on the valuation date 26.7 27.1 28.8 29.1 Life expectancy for member aged 60, 15 years after the valuation date 27.8 28.1 30.0 30.3 The mortality assumptions used in the UK scheme valuations are based on standard tables published by the Institute and Faculty of Actuaries which were adjusted in line with the actual experience of the relevant schemes. The table shows that a member retiring at age 60 at 31 December 2022 is assumed to live for, on average, 26.7 years for a male and 28.8 years for a female. In practice there will be much variation between individual members but these assumptions are expected to be appropriate across all members. It is assumed that younger members will live longer in retirement than those retiring now. This reflects the expectation that mortality rates will continue to fall over time as medical science and standards of living improve. To illustrate the degree of improvement assumed, the table also shows the life expectancy for members aged 45 now, when they retire in 15 years time at age 60. The Group uses the CMI mortality projections model and in line with actuarial industry recommendations has placed no weight on 2020 and 2021 mortality experience. The persistence of excess deaths during 2022 has highlighted the potential longer term impacts of COVID-19 and the Group has applied a 4 per cent scaling factor to its base mortality tables at December 2022 to allow for this impact on member mortality. This led to a c.1 per cent reduction in the defined benefit obligation. (v) Amount, timing and uncertainty of future cash flows Risk exposure of the defined benefit schemes While the Group is not exposed to any unusual, entity-specific or scheme-specific risks in its defined benefit pension schemes, it is exposed to a number of significant risks, detailed below: Inflation rate risk: The majority of the plans’ benefit obligations are linked to inflation both in deferment and once in payment. Higher inflation will lead to higher liabilities although this will be materially offset by holdings of inflation-linked gilts and, in most cases, caps on the level of inflationary increases are in place to protect against extreme inflation. Interest rate risk: The defined benefit obligation is determined using a discount rate derived from yields on AA-rated corporate bonds. A decrease in corporate bond yields will increase plan liabilities although this will be materially offset by an increase in the value of bond holdings and through the use of derivatives. Longevity risk: The majority of the schemes’ obligations are to provide benefits for the life of the members so increases in life expectancy will result in an increase in the plans’ liabilities. Investment risk: Scheme assets are invested in a diversified portfolio of debt securities, equities and other return-seeking assets. If the assets underperform the discount rate used to calculate the defined benefit obligation, it will reduce the surplus or increase the deficit. Volatility in asset values and the discount rate will lead to volatility in the net pension asset on the Group’s balance sheet and in other comprehensive income. To a lesser extent this will also lead to volatility in the pension expense in the Group’s income statement. The ultimate cost of the defined benefit obligations to the Group will depend upon actual future events rather than the assumptions made. The assumptions made are unlikely to be borne out in practice and as such the cost may be higher or lower than expected. Sensitivity analysis The effect of reasonably possible changes in key assumptions on the value of scheme liabilities and the resulting pension charge in the Group’s income statement and on the net defined benefit pension scheme asset, for the Group’s three most significant schemes, is set out below. The sensitivities provided assume that all other assumptions and the value of the schemes’ assets remain unchanged, and are not intended to represent changes that are at the extremes of possibility. The calculations are approximate in nature and full detailed calculations could lead to a different result. It is unlikely that isolated changes to individual assumptions will be experienced in practice. Due to the correlation of assumptions, aggregating the effects of these isolated changes may not be a reasonable estimate of the actual effect of simultaneous changes in multiple assumptions. Effect of reasonably possible alternative assumptions Increase (decrease) in the income statement charge (Increase) decrease in the 2022 £m 2021 £m 2022 £m 2021 £m Inflation (including pension increases) 1 : Increase of 0.1 per cent 13 12 251 481 Decrease of 0.1 per cent (13) (12) (245) (475) Discount rate 2 : Increase of 0.1 per cent (25) (24) (379) (774) Decrease of 0.1 per cent 24 23 388 795 Expected life expectancy of members: Increase of one year 38 44 745 1,934 Decrease of one year (39) (42) (762) (1,852) 1 At 31 December 2022, the assumed rate of RPI inflation is 3.13 per cent and CPI inflation 2.69 per cent (2021: RPI 3.21 per cent and CPI 2.92 per cent). 2 At 31 December 2022, the assumed discount rate is 4.93 per cent (2021: 1.94 per cent). Sensitivity analysis method and assumptions The sensitivity analysis above reflects the impact on the liabilities of the Group’s three most significant schemes which account for over 90 per cent of the Group’s defined benefit obligations. While differences in the underlying liability profiles for the remainder of the Group’s pension arrangements mean that they may exhibit slightly different sensitivities to variations in these assumptions, the sensitivities provided above are indicative of the impact across the Group as a whole. The inflation assumption sensitivity applies to the assumed rate of increase in both the Consumer Price Index (CPI) and the Retail Price Index (RPI), and includes the impact on the rate of increases to pensions, both before and after retirement. These pension increases are linked to inflation (either CPI or RPI) subject to certain minimum and maximum limits. The sensitivity analysis (including the inflation sensitivity) does not include the impact of any change in the rate of salary increases as pensionable salaries have been frozen since 2 April 2014. The life expectancy assumption has been applied by allowing for an increase/decrease in life expectation from age 60 of one year, based upon the approximate weighted average age for each scheme. While this is an approximate approach and will not give the same result as a one year increase in life expectancy at every age, it provides an appropriate indication of the potential impact on the schemes from changes in life expectancy. There was no change in the methods and assumptions used in preparing the sensitivity analysis from the prior year. Asset-liability matching strategies The main schemes’ assets are invested in a diversified portfolio. Whilst c.50 per cent are held to generate the long-term returns required to support the funding position of the schemes, the remainder is invested in liability-driven investment (LDI) strategies which hedge the material risk exposures of the schemes. The investment strategy is not static and will evolve to reflect the structure of liabilities within the schemes. Specific strategies for each pension plan are independently determined by the responsible governance body for each scheme and in consultation with the employer. A significant goal of the strategies adopted by the schemes is to reduce volatility caused by changes in market expectations of interest rates and inflation. In the main schemes, this is achieved by investing scheme assets in bonds, primarily fixed interest gilts and index linked gilts, and by entering into interest rate and inflation swap arrangements. The assets in these LDI strategies represented 48 per cent of scheme assets at 31 December 2022. These investments are structured to take into account the profile of scheme liabilities and actively managed to reflect both changing market conditions and changes to the liability profile. At 31 December 2022 the asset-liability matching strategy mitigated around 119 per cent of the liability sensitivity to interest rate movements and around 123 per cent of the liability sensitivity to inflation movements. In addition, a small amount of interest rate sensitivity arises through holdings of corporate and other debt securities. The higher level of hedging provides greater protection to the funding position of the schemes. The schemes’ funding position remained robust and did not experience any material impact from the market volatility seen in the latter part of last year. Asset prices fell in line with the broader market and hedges fell in value as interest rates rose, and a similar impact was experienced on liability valuations which also fell in value given the portfolio was almost fully hedged. The Group’s schemes use LDI strategies to achieve this outcome and, as the hedging was maintained throughout the crisis, the strategy performed as expected. All collateral requirements in respect of the LDI strategies were met, with no support required from the Group beyond payment of scheduled contributions. On 28 January 2020, the main schemes entered into a £10 billion longevity insurance arrangement to hedge part of the schemes’ exposure to unexpected increases in life expectancy. This arrangement forms part of the schemes’ investment portfolio and will provide income to the schemes in the event that pensions are paid out for longer than expected. The transaction was structured as a pass-through with Scottish Widows as the insurer, and onwards reinsurance to Pacific Life Re Limited. On 28 January 2022, the Lloyds Bank Pension Scheme No. 1 entered into an additional £5.5 billion longevity insurance arrangement. The transaction is structured as a pass-through with Scottish Widows as the insurer, and onwards reinsurance to SCOR SE – UK Branch. At 31 December 2022 the value of scheme assets included £(100) million representing the value of the longevity swaps (after allowing for the impact on the IAS 19 liabilities of the revisions to the base mortality assumptions). In total the schemes have now hedged around 32 per cent of their longevity risk exposure. Maturity profile of defined benefit obligation The following table provides information on the weighted average duration of the defined benefit pension obligation and the distribution and timing of benefit payments: 2022 Years 2021 Years Duration of the defined benefit obligation 15 17 Maturity analysis of benefits expected to be paid: 2022 £m 2021 £m Within 12 months 1,409 1,352 Between 1 and 2 years 1,464 1,450 Between 2 and 5 years 4,678 4,651 Between 5 and 10 years 8,930 8,993 Between 10 and 15 years 9,296 9,668 Between 15 and 25 years 17,479 18,671 Between 25 and 35 years 12,720 13,846 Between 35 and 45 years 6,138 6,987 In more than 45 years 1,685 2,116 Maturity analysis method and assumptions The projected benefit payments are based on the assumptions underlying the assessment of the obligations, including allowance for expected future inflation. They are shown in their undiscounted form and therefore appear large relative to the discounted assessment of the defined benefit obligations recognised in the Group’s balance sheet. They are in respect of benefits that have been accrued prior to the respective year-end date only and make no allowance for any benefits that may have been accrued subsequently. Defined contribution schemes The Group operates a number of defined contribution pension schemes in the UK and overseas, principally Your Tomorrow and the defined contribution sections of the Lloyds Bank Pension Scheme No. 1. During the year ended 31 December 2022 the charge to the income statement in respect of defined contribution schemes was £330 million (2021: £302 million; 2020: £319 million), representing the contributions payable by the employer in accordance with each scheme’s rules. Other post-retirement benefit schemes The Group operates a number of schemes which provide post-retirement healthcare benefits to certain employees, retired employees and their dependants. The principal scheme relates to former Lloyds Bank staff and under this scheme the Group has undertaken to meet the cost of post-retirement healthcare for all eligible former employees (and their dependants) who retired prior to 1 January 1996. The Group has entered into an insurance contract to provide these benefits and a provision has been made for the estimated cost of future insurance premiums payable. For the principal post-retirement healthcare scheme, the latest actuarial valuation of the liability was carried out at 31 December 2022 by qualified independent actuaries. The principal assumptions used were as set out above, except that the rate of increase in healthcare premiums has been assumed at 6.74 per cent (2021: 6.82 per cent).

DEFERRED TAX	NOTE 36: DEFERRED TAX The Group’s deferred tax assets and liabilities are as follows: Statutory position 2022 £m 2021 £m Tax disclosure 2022 £m 2021 £m Deferred tax assets 5,228 3,118 Deferred tax assets 8,627 7,095 Deferred tax liabilities (216) (39) Deferred tax liabilities (3,615) (4,016) Asset at 31 December 5,012 3,079 Asset at 31 December 5,012 3,079 The statutory position reflects the deferred tax assets and liabilities as disclosed in the consolidated balance sheet and takes into account the ability of the Group to net assets and liabilities where there is a legally enforceable right of offset. The tax disclosure of deferred tax assets and liabilities ties to the amounts outlined in the tables below which splits the deferred tax assets and liabilities by type, before such netting. Movements in deferred tax assets and liabilities (before taking into consideration the offsetting of balances within the same taxing jurisdiction) can be summarised as follows: Deferred tax assets Tax Property, Provisions Share- Pension Derivatives Asset Other Total At 1 January 2021 4,064 668 254 29 56 159 29 268 5,527 Credit (charge) to the income statement 959 76 12 (8) 15 541 (29) (49) 1,517 Credit (charge) to other comprehensive income – – 36 – (2) – – – 34 Other credit to equity – – – 17 – – – – 17 At 31 December 2021 5,023 744 302 38 69 700 – 219 7,095 Credit (charge) to the income statement 39 (238) 113 (5) (22) (205) 8 62 (248) Credit (charge) to other comprehensive income – – (155) – – 1,928 – – 1,773 Acquisitions 4 – – – – – – – 4 Other credit to equity – – – 3 – – – – 3 At 31 December 2022 5,066 506 260 36 47 2,423 8 281 8,627 Deferred tax liabilities Capitalised Long-term Acquisition Pension Derivatives Asset revaluations 1 £m Other Total At 1 January 2021 (228) (843) (372) (392) (756) – (240) (2,831) (Charge) credit to the income statement (47) (319) 20 (93) (567) (27) (93) (1,126) (Charge) credit to other comprehensive income – – – (846) 814 (29) – (61) Exchange and other adjustments – – – – – – 2 2 At 31 December 2021 (275) (1,162) (352) (1,331) (509) (56) (331) (4,016) (Charge) credit to the income statement 118 107 21 29 (32) – (164) 79 Credit to other comprehensive income – – – 283 – 56 – 339 Acquisitions (5) – (1) – – – – (6) Exchange and other adjustments – – – – – – (11) (11) At 31 December 2022 (162) (1,055) (332) (1,019) (541) – (506) (3,615) 1 Financial assets at fair value through other comprehensive income. At 31 December 2022 the Group carried net deferred tax assets on its balance sheet of £5,228 million (2021: £3,118 million) principally relating to tax losses carried forward. Estimation of income taxes includes the assessment of recoverability of deferred tax assets. Deferred tax assets are only recognised to the extent that they are considered more likely than not to be recoverable based on existing tax laws and forecasts of future taxable profits against which the underlying tax deductions can be utilised. The Group has recognised a deferred tax asset of £5,066 million (2021: £5,023 million) in respect of trading losses carried forward. Substantially all of these losses have arisen in Bank of Scotland plc and Lloyds Bank plc, and they will be utilised as taxable profits arise in those legal entities in future periods. The Group’s expectations of future UK taxable profits require management judgement, and take into account the Group’s long-term financial and strategic plans and anticipated future tax-adjusting items. In making this assessment, account is taken of business plans, the Board-approved operating plan and the expected future economic outlook as set out in the strategic report, as well as the risks associated with future regulatory, climate-related and other change, in order to produce a base case forecast of future UK taxable profits. Under current law there is no expiry date for UK trading losses not yet utilised, and given the forecast of future profitability and the Group’s commitment to the UK market, in management’s judgement it is more likely than not that the value of the losses will be recovered by the Group while still operating as a going concern. Banking tax losses that arose before 1 April 2015 can only be used against 25 per cent of taxable profits arising after 1 April 2016, and they cannot be used to reduce the surcharge on banking profits. These restrictions in utilisation mean that the value of the deferred tax asset in respect of tax losses is only expected to be fully recovered by 2036 (2021: 2047) in the base case forecast. The rate of recovery of the Group’s tax loss asset is not a straight line, being affected by the relative profitability of the different legal entities in future periods, and the relative size of their tax losses carried forward. It is expected in the base case that 90 per cent of the value will be recovered by 2032, when Bank of Scotland plc will have utilised all of its available tax losses. It is possible that future tax law changes could materially affect the timing of recovery and the value of these losses ultimately realised by the Group. Deferred tax not recognised A deferred tax asset of £46 million (2021: £5 million) has been recognised in respect of the future tax benefit of certain expenses of the life assurance business. The increase is mainly due to investment market falls in 2022, which have increased the amount of unutilised expenses carried forward and expected to be offset against taxable investment returns in the medium term. The deferred tax asset not recognised in respect of the remaining expenses is £125 million (2021: £226 million), and these expenses can be carried forward indefinitely. The unrecognised deferred tax asset has decreased in 2022 mainly due to higher expected investment returns in the long term projections for the life insurance business driven by interest rate rises. This has reduced the net amount of unutilised expenses in the long term. Deferred tax assets of £156 million (2021: £167 million) have not been recognised in respect of £619 million of UK tax losses and other temporary differences which can only be used to offset future capital gains. UK capital losses can be carried forward indefinitely. No deferred tax has been recognised in respect of foreign trade losses where it is not more likely than not that we will be able to utilise them in future periods. Of the asset not recognised, £53 million (2021: £41 million) relates to losses that will expire if not used within 20 years, and £9 million (2021: £7 million) relates to losses with no expiry date. As a result of parent company exemptions on dividends from subsidiaries and on capital gains on disposal there are no significant taxable temporary differences associated with investments in subsidiaries, branches, associates and joint arrangements.

Disclosure of other provisions [abstract]
OTHER PROVISIONS	NOTE 37: OTHER PROVISIONS Provisions Regulatory Other Total At 1 January 2022 200 1,156 736 2,092 Exchange and other adjustments 1 17 27 45 Provisions applied – (625) (413) (1,038) Charge for the year 122 255 333 710 At 31 December 2022 323 803 683 1,809 Provisions for financial commitments and guarantees Provisions are recognised for expected credit losses on undrawn loan commitments and financial guarantees. See also note 18. Regulatory and legal provisions In the course of its business, the Group is engaged in discussions with the PRA, FCA and other UK and overseas regulators and other governmental authorities on a range of matters. The Group also receives complaints in connection with its past conduct and claims brought by or on behalf of current and former employees, customers, investors and other third parties and is subject to legal proceedings and other actions. Where significant, provisions are held against the costs expected to be incurred in relation to these matters and matters arising from related internal reviews. During the year ended 31 December 2022 the Group charged a further £255 million in respect of legal actions and other regulatory matters and the unutilised balance at 31 December 2022 was £803 million (31 December 2021: £1,156 million). The most significant items are as follows. HBOS Reading – review The Group continues to apply the recommendations from Sir Ross Cranston’s review, issued in December 2019, including a reassessment of direct and consequential losses by an independent panel (the Foskett Panel), an extension of debt relief and a wider definition of de facto directors. The Foskett Panel's full scope and methodology was published on 7 July 2020. The Foskett Panel’s stated objective is to consider cases via a non-legalistic and fair process and to make their decisions in a generous, fair and common sense manner, assessing claims against an expanded definition of the fraud and on a lower evidential basis. Following the emergence of the first outcomes of the Foskett Panel through 2021, the Group charged a further £790 million in the year ended 31 December 2021. This included operational costs in relation to Dame Linda Dobbs's review, which is considering whether the issues relating to HBOS Reading were investigated and appropriately reported by the Group during the period from January 2009 to January 2017, and other programme costs. A significant proportion of the charge related to the estimated future awards from the Foskett Panel. The Foskett Panel had shared outcomes on a limited subset of the total population which covers a wide range of businesses and different claim characteristics. The estimated awards provision recognised at 31 December 2021 was therefore materially dependent on the assumption that the limited number of awards to date were representative of the full population of cases. In June 2022, the Foskett Panel announced an alternative option, in the form of a fixed sum award which could be accepted as an alternative to participation in the full re-review process, to support earlier resolution of claims for those deemed by the Foskett Panel to be victims of the fraud. Around half the population have now had outcomes via this new process. Extrapolating the Group’s experience to date resulted in an increase to the provision of £50 million in the year (all in the fourth quarter). Notwithstanding the settled claims and the increase in coverage which builds confidence in the full estimated cost, uncertainties remain and the final outcome could be different from the current provision once the re-review is concluded by the Foskett Panel. There is no confirmed timeline for the completion of the Foskett Panel re-review process nor the review by Dame Linda Dobbs. The Group is committed to implementing Sir Ross's recommendations in full. Payment protection insurance The Group has incurred costs for PPI over a number of years totalling £21,960 million. The Group continues to challenge PPI litigation cases, with mainly legal fees and operational costs associated with litigation activity recognised within regulatory and legal provisions, including a charge in the fourth quarter. PPI litigation remains inherently uncertain, with a number of key court judgments due to be delivered in 2023. Customer claims in relation to insurance branch business in Germany The Group continues to receive claims from customers in Germany relating to policies issued by Clerical Medical Investment Group Limited (subsequently renamed Scottish Widows Limited), with smaller numbers of claims received from customers in Austria and Italy. The total provision made to 31 December 2022, was £709 million (31 December 2021: £695 million) with £11 million utilisation of the provision during the year, leaving an unutilised provision at 31 December 2022 of £88 million. The ultimate financial effect, which could be significantly different from the current provision, will be known only once all relevant claims have been resolved. Other Following the sale of TSB Banking Group plc, the Group raised a provision of £665 million in relation to various ongoing commitments in respect of the divestment. At 31 December 2022, a provision of £22 million remained unutilised; the Group expects the majority of the remaining provision to be utilised in the next twelve months and the provision to be fully utilised by 31 December 2024. The Group carries provisions of £112 million (2021: £114 million) in respect of dilapidations, rent reviews and other property-related matters. Provisions are also made for staff and other costs related to Group restructuring initiatives at the point at which the Group becomes committed to the expenditure; at 31 December 2022 provisions of £112 million (31 December 2021: £189 million) were held. The Group carries provisions of £86 million (2021: £94 million) for indemnities and other matters relating to legacy business disposals in prior years. Whilst there remains significant uncertainty as to the timing of the utilisation of the provisions, the Group expects the majority of the remaining provisions to have been utilised by 31 December 2026.

The claims of holders of preference shares and preferred securities are generally junior to those of the holders of undated subordinated liabilities, which in turn are junior to the claims of holders of the dated subordinated liabilities.

Lloyds Banking Group Long Term Share Plan The plan, introduced in 2021, replaced the Executive Group Ownership Share Plan and is intended to provide alignment to the Group’s aim of delivering sustainable returns to shareholders, supported by its values and behaviours. 2022 Number of shares 2021 Number of shares Outstanding at 1 January 77,883,068 – Granted 108,513,202 83,456,304 Vested – – Forfeited (14,448,527) (5,573,236) Dividend award – – Outstanding at 31 December 171,947,743 77,883,068 The weighted average fair value of awards granted in the year was £0.36 (2021: £0.36). Assumptions at 31 December 2022 The fair value calculations at 31 December 2022 for grants made in the year, using Black-Scholes models and Monte Carlo simulation, are based on the following assumptions: SAYE Executive Long Term Share Plan Weighted average risk-free interest rate 4.33% 3.20% 1.01% Weighted average expected life 3.3 years 1.2 years 3.6 years Weighted average expected volatility 28% 27% 33% Weighted average expected dividend yield 5.3% 5.3% 5.3% Weighted average share price £0.42 £0.47 £0.43 Weighted average exercise price £0.39 Nil Nil Expected volatility is a measure of the amount by which the Group’s shares are expected to fluctuate during the life of an option. The expected volatility is estimated based on the historical volatility of the closing daily share price over the most recent period that is commensurate with the expected life of the option. The historical volatility is compared to the implied volatility generated from market traded options in the Group’s shares to assess the reasonableness of the historical volatility and adjustments made where appropriate. Share Incentive Plans Free shares An award of shares may be made annually to employees up to a maximum of £3,600. The shares awarded are held in trust for a mandatory period of three three No award was made in 2022. On 25 March 2021, the Group made an award of 1,017 shares to all eligible employees. The number of shares awarded was 67,658,976, with an average fair value of £0.42 based on the market price at the date of award. Matching shares The Group undertakes to match shares purchased by employees up to the value of £45 per month; these matching shares are held in trust for a mandatory period of three years on the employee’s behalf, during which period the employee is entitled to any dividends paid on such shares. The award is subject to a non-market based condition: if an employee leaves within this three-year period for other than a ‘good’ reason, all of the matching shares are forfeited. Similarly, if the employees sell their purchased shares within three years, their matching shares are forfeited. The number of shares awarded relating to matching shares in 2022 was 43,378,504 (2021: 46,621,026), with an average fair value of £0.45 (2021: £0.44), based on market prices at the date of award. Fixed share awards Fixed share awards were introduced in 2014 in order to ensure that total fixed remuneration is commensurate with role and to provide a competitive reward package for certain Lloyds Banking Group employees, with an appropriate balance of fixed and variable remuneration, in line with regulatory requirements. The fixed share awards are delivered in Lloyds Banking Group plc shares, and were initially released over five The fixed share award is not subject to any performance conditions, performance adjustment or clawback. On an employee leaving the Group, there is no change to the timeline for which shares will become unrestricted.

In addition, the Group has provided £1,466 million (2021: £1,265 million) of financing to these companies on which it received £98 million (2021: £86 million) of interest income in the year.

CONTINGENT LIABILITIES, COMMITM

CONTINGENT LIABILITIES, COMMITMENTS, AND GUARANTEES	12 Months Ended

Disclosure of commitments and contingent liabilities [Abstract]
CONTINGENT LIABILITIES, COMMITMENTS AND GUARANTEES	NOTE 47: CONTINGENT LIABILITIES, COMMITMENTS AND GUARANTEES Interchange fees With respect to multi-lateral interchange fees (MIFs), the Group is not a party in the ongoing or threatened litigation which involves the card schemes Visa and Mastercard (as described below). However, the Group is a member/licensee of Visa and Mastercard and other card schemes. The litigation in question is as follows: • Litigation brought by or on behalf of retailers against both Visa and Mastercard in the English Courts, in which retailers are seeking damages on grounds that Visa and Mastercard’s MIFs breached competition law (this includes a judgment of the Supreme Court in June 2020 upholding the Court of Appeal’s finding in 2018 that certain historic interchange arrangements of Mastercard and Visa infringed competition law) • Litigation brought on behalf of UK consumers in the English Courts against Mastercard Any impact on the Group of the litigation against Visa and Mastercard remains uncertain at this time, such that it is not practicable for the Group to provide an estimate of any potential financial effect. Insofar as Visa is required to pay damages to retailers for interchange fees set prior to June 2016, contractual arrangements to allocate liability have been agreed between various UK banks (including the Group) and Visa Inc, as part of Visa Inc’s acquisition of Visa Europe in 2016. These arrangements cap the maximum amount of liability to which the Group may be subject and this cap is set at the cash consideration received by the Group for the sale of its stake in Visa Europe to Visa Inc in 2016. In 2016, the Group received Visa preference shares as part of the consideration for the sale of its shares in Visa Europe. A release assessment is carried out by Visa on certain anniversaries of the sale (in line with the Visa Europe sale documentation) and as a result, some Visa preference shares may be converted into Visa Inc Class A common stock. Any such release and any subsequent sale of Visa common stock does not impact the contingent liability. LIBOR and other trading rates Certain Group companies, together with other panel banks, have been named as defendants in ongoing private lawsuits, including purported class action suits, in the US in connection with their roles as panel banks contributing to the setting of US Dollar, Japanese Yen and Sterling London Interbank Offered Rate and the Australian BBSW reference rate. Certain Group companies are also named as defendants in (i) UK-based claims; and (ii) two Dutch class actions, raising LIBOR manipulation allegations. A number of claims against the Group in the UK relating to the alleged mis-sale of interest rate hedging products also include allegations of LIBOR manipulation. It is currently not possible to predict the scope and ultimate outcome on the Group of any private lawsuits or any related challenges to the interpretation or validity of any of the Group’s contractual arrangements, including their timing and scale. As such, it is not practicable to provide an estimate of any potential financial effect. Tax authorities The Group has an open matter in relation to a claim for group relief of losses incurred in its former Irish banking subsidiary, which ceased trading on 31 December 2010. In 2013, HMRC informed the Group that its interpretation of the UK rules means that the group relief is not available. In 2020, HMRC concluded their enquiry into the matter and issued a closure notice. The Group’s interpretation of the UK rules has not changed and hence it has appealed to the First Tier Tax Tribunal, with a hearing expected in 2023. If the final determination of the matter by the judicial process is that HMRC’s position is correct, management estimate that this would result in an increase in current tax liabilities of approximately £875 million (including interest) and a reduction in the Group’s deferred tax asset of approximately £295 million. The Group, having taken appropriate advice, does not consider that this is a case where additional tax will ultimately fall due. There are a number of other open matters on which the Group is in discussions with HMRC (including the tax treatment of certain costs arising from the divestment of TSB Banking Group plc), none of which is expected to have a material impact on the financial position of the Group. Motor commission review Following the FCA’s Motor Market review, the Group has received a number of complaints, some of which are with the Financial Ombudsman Service, in respect of commission arrangements. It is currently not possible to predict the ultimate outcome of the complaints, including the financial impact or the scope or nature of remediation requirements, if any, or any related challenges to the interpretation or validity of any of the Group’s historical motor commission arrangements. Other legal actions and regulatory matters In addition, in the course of its business the Group is subject to other complaints and threatened or actual legal proceedings (including class or group action claims) brought by or on behalf of current or former employees, customers, investors or other third parties, as well as legal and regulatory reviews, challenges, investigations and enforcement actions, which could relate to a number of issues, including financial, environmental or other regulatory matters, both in the UK and overseas. Where material, such matters are periodically reassessed, with the assistance of external professional advisers where appropriate, to determine the likelihood of the Group incurring a liability. In those instances where it is concluded that it is more likely than not that a payment will be made, a provision is established based on management’s best estimate of the amount required at the relevant balance sheet date. In some cases it will not be possible to form a view, for example because the facts are unclear or because further time is needed to assess properly the merits of the case, and no provisions are held in relation to such matters. In these circumstances, specific disclosure in relation to a contingent liability will be made where material. However, the Group does not currently expect the final outcome of any such case to have a material adverse effect on its financial position, operations or cash flows. Where there is a contingent liability related to an existing provision the relevant disclosures are included within note 37.

Capital commitments Excluding commitments in respect of investment property (note 26), capital expenditure contracted but not provided for at 31 December 2022 amounted to £1,663 million (2021: £1,034 million). Of this amount, £1,663 million (2021: £1,034 million) related to assets to be leased to customers under operating leases. The Group’s management is confident that future net revenues and funding will be sufficient to cover these commitments.

STRUCTURED ENTITIES

STRUCTURED ENTITIES	12 Months Ended

Disclosure of unconsolidated structured entities [line items]
STRUCTURED ENTITIES	NOTE 48: STRUCTURED ENTITIES The Group’s interests in structured entities are both consolidated and unconsolidated. Details of the Group’s interests in consolidated structured entities are set out in note 30 for securitisations and covered bond vehicles, note 35 for structured entities associated with the Group’s pension schemes, and below in part (A) and (B). Details of the Group’s interests in unconsolidated structured entities are included below in part (C). (A) Asset-backed conduits In addition to the structured entities discussed in note 30, which are used for securitisation and covered bond programmes, the Group sponsors an active asset-backed conduit, Cancara, which invests in client receivables and debt securities. The total consolidated exposure of Cancara at 31 December 2022 was £2,357 million (2021: £1,745 million), comprising £1,464 million of loans and advances (2021: £889 million), £850 million of debt securities (2021: £780 million) and £43 million of financial assets at fair value through profit or loss (2021: £76 million). All lending assets and debt securities held by the Group in Cancara are restricted in use, as they are held by the collateral agent for the benefit of the commercial paper investors and the liquidity providers only. The Group provides liquidity facilities to Cancara under terms that are usual and customary for standard lending activities in the normal course of the Group’s banking activities. During 2022 there have continued to be planned drawdowns on certain liquidity facilities for balance sheet management purposes, supporting the programme to provide funding alongside the proceeds of the asset-backed commercial paper issuance. The Group could be asked to provide support under the contractual terms of these arrangements including, for example, if Cancara experienced a shortfall in external funding, which may occur in the event of market disruption. The external assets in Cancara are consolidated in the Group’s financial statements. (B) Consolidated collective investment vehicles and limited partnerships The assets of the Insurance business held in consolidated collective investment vehicles, such as Open-Ended Investment Companies and limited partnerships, are not directly available for use by the Group. However, the Group’s investment in the majority of these collective investment vehicles is readily realisable. As at 31 December 2022, the total carrying value of these consolidated collective investment vehicle assets and liabilities held by the Group was £54,749 million (2021: £60,352 million). The Group has no contractual arrangements (such as liquidity facilities) that would require it to provide financial or other support to the consolidated collective investment vehicles; the Group has not previously provided such support and has no current intentions to provide such support. (C) Unconsolidated collective investment vehicles and limited partnerships The Group’s direct interests in unconsolidated structured entities comprise investments in collective investment vehicles, such as Open-Ended Investment Companies, and limited partnerships with a total carrying value of £68,913 million at 31 December 2022 (2021: £74,916 million), included within financial assets designated at fair value through profit and loss (see note 16). These investments include both those entities managed by third parties and those managed by the Group. At 31 December 2022, the total asset value of these unconsolidated structured entities, including the portion in which the Group has no interest, was £2,176 billion (2021: £2,597 billion). Given the nature of these investments, the Group’s maximum exposure to loss is equal to the carrying value of the investment. However, the Group’s investments in these entities are primarily held to match policyholder liabilities in the Insurance division and the majority of the risk from a change in the value of the Group’s investment is matched by a change in policyholder liabilities. The collective investment vehicles are primarily financed by investments from investors in the vehicles. During the year the Group has not provided any non-contractual financial or other support to these entities and has no current intention of providing any financial or other support. There were no transfers from/to these unconsolidated collective investment vehicles and limited partnerships. The Group considers itself the sponsor of a structured entity where it is primarily involved in the design and establishment of the structured entity and further where the Group transfers assets to the structured entity, markets products associated with the structured entity in its own name and/or provides guarantees regarding the structured entity’s performance. The Group sponsors a range of diverse investment funds and limited partnerships where it acts as the fund manager or equivalent decision-maker and markets the funds under one of the Group’s brands. The Group earns fees from managing the investments of these funds. The investment management fees that the Group earned from these entities, including those in which the Group held no ownership interest at 31 December 2022, are reported in note 6.

It is a measure as at a specific date and may be significantly different from the amount which will actually be paid or received on maturity or settlement date. Wherever possible, fair values have been calculated using unadjusted quoted market prices in active markets for identical instruments to those held by the Group. Where quoted market prices are not available, or are unreliable because of poor liquidity, fair values have been determined using valuation techniques which, to the extent possible, use market observable inputs, but in some cases use non-market observable inputs. Valuation techniques used include discounted cash flow analysis and pricing models and, where appropriate, comparison to instruments with characteristics similar to those of the instruments held by the Group. The Group measures valuation adjustments for its derivative exposures on the same basis as the derivatives are managed. The carrying amount of the following financial instruments is a reasonable approximation of fair value: cash and balances at central banks, items in the course of collection from banks, items in course of transmission to banks and notes in circulation. Liabilities arising from non-participating investment contracts are carried at fair value. Fair values have not been disclosed for discretionary participating investment contracts. There is currently no agreed definition of fair valuation for discretionary participation features applied under IFRS and therefore the range of possible fair values of these contracts cannot be measured reliably. Because a variety of estimation techniques are employed and significant estimates made, comparisons of fair values between financial institutions may not be meaningful. Readers of these financial statements are thus advised to use caution when using this data to evaluate the Group’s financial position. Fair value information is not provided for items that are not financial instruments or for other assets and liabilities which are not carried at fair value in the Group’s consolidated balance sheet. These items include intangible assets, such as brands and acquired credit card relationships; premises and equipment; and shareholders’ equity. These items are material and accordingly the Group believes that any fair value information presented would not represent the underlying value of the Group. Valuation control framework The key elements of the control framework for the valuation of financial instruments include model validation, product implementation review and independent price verification. These functions are carried out by appropriately skilled risk and finance teams, independent of the business area responsible for the products. Model validation covers both qualitative and quantitative elements relating to new models. In respect of new products, a product implementation review is conducted pre and post-trading. Pre-trade testing ensures that the new model is integrated into the Group’s systems and that the profit and loss and risk reporting are consistent throughout the trade lifecycle. Post-trade testing examines the explanatory power of the implemented model, actively monitoring model parameters and comparing in-house pricing to external sources. Independent price verification procedures cover financial instruments carried at fair value. The frequency of the review is matched to the availability of independent data, monthly being the minimum. Valuation differences in breach of established thresholds are escalated to senior management. The results from independent pricing and valuation reserves are reviewed monthly by senior management. Formal committees, consisting of senior risk, finance and business management, meet at least quarterly to discuss and approve valuations in more judgemental areas, in particular for unquoted equities, structured credit, over-the-counter options and the credit valuation adjustment (CVA), funding valuation adjustment (FVA) and other valuation adjustments. Valuation of financial assets and liabilities Assets and liabilities carried at fair value or for which fair values are disclosed have been classified into three levels according to the quality and reliability of information used to determine the fair values. Level 1 Level 1 fair value measurements are those derived from unadjusted quoted prices in active markets for identical assets or liabilities. Products classified as level 1 predominantly comprise listed equity shares, treasury bills and other government securities. Level 2 Level 2 valuations are those where quoted market prices are not available, for example where the instrument is traded in a market that is not considered to be active or valuation techniques are used to determine fair value and where these techniques use inputs that are based significantly on observable market data. Examples of such financial instruments include most over-the-counter derivatives, financial institution issued securities, certificates of deposit and certain asset-backed securities. Level 3 Level 3 portfolios are those where at least one input which could have a significant effect on the instrument’s valuation is not based on observable market data. Such instruments would include the Group’s venture capital and unlisted equity investments which are valued using various valuation techniques that require significant management judgement in determining appropriate assumptions, including earnings multiples and estimated future cash flows. Certain of the Group’s asset-backed securities, loans and advances recognised at fair value and derivatives are also classified as level 3. Transfers out of the level 3 portfolio arise when inputs that could have a significant impact on the instrument’s valuation become market observable after previously having been non-market observable. In the case of asset-backed securities this can arise if more than one consistent independent source of data becomes available. Conversely, transfers into the portfolio arise when consistent sources of data cease to be available. (3) Financial assets and liabilities carried at fair value (A) Financial assets, excluding derivatives Valuation hierarchy At 31 December 2022, the Group’s financial assets carried at fair value, excluding derivatives, totalled £203,763 million (2021: £234,908 million). The table below analyses these financial assets by balance sheet classification, asset type and valuation methodology (level 1, 2 or 3, as described on page F- 107 ). The fair value measurement approach is recurring in nature. There were no significant transfers between level 1 and 2 during the year.

The discount rates are derived from market observable interest rates, a risk margin that reflects loan credit ratings and an incremental illiquidity premium based on historical spreads at origination on similar loans. Debt securities Debt securities measured at fair value and classified as level 2 are valued by discounting expected cash flows using an observable credit spread applicable to the particular instrument. Where there is limited trading activity in debt securities, the Group uses valuation models, consensus pricing information from third-party pricing services and broker or lead manager quotes to determine an appropriate valuation. Debt securities are classified as level 3 if there is a significant valuation input that cannot be corroborated through market sources or where there are materially inconsistent values for an input. Asset classes classified as level 3 mainly comprise venture capital investments. Equity investments Unlisted equity and fund investments are valued using different techniques in accordance with the Group’s valuation policy and International Private Equity and Venture Capital Guidelines. Depending on the business sector and the circumstances of the investment, unlisted equity valuations are based on earnings multiples, net asset values or discounted cash flows. • A number of earnings multiples are used in valuing the portfolio including price earnings, earnings before interest and tax and earnings before interest, tax, depreciation and amortisation. The particular multiple selected is appropriate for the size and type of business being valued and is derived by reference to the current market-based multiple. Consideration is given to the risk attributes, growth prospects and financial gearing of comparable businesses when selecting the appropriate multiple • Discounted cash flow valuations use estimated future cash flows, usually based on management forecasts, with the application of appropriate exit yields or terminal multiples and discounted using rates appropriate to the specific investment, business sector or recent economic rates of return. Recent transactions involving the sale of similar businesses may sometimes be used as a frame of reference in deriving an appropriate multiple • For fund investments the most recent capital account value calculated by the fund manager is used as the basis for the valuation and adjusted, if necessary, to align valuation techniques with the Group’s valuation policy Unlisted equity investments and investments in property partnerships held in the life assurance funds are valued using third-party valuations. Management take account of any pertinent information, such as recent transactions and information received on particular investments, to adjust the third-party valuations where necessary. (B) Financial liabilities, excluding derivatives Valuation hierarchy At 31 December 2022, the Group’s financial liabilities carried at fair value, excluding derivatives, comprised its financial liabilities at fair value through profit or loss and totalled £17,755 million (2021: £23,123 million). The table below analyses these financial liabilities by balance sheet classification and valuation methodology (level 1, 2 or 3, as described on page F- 107 ). The fair value measurement approach is recurring in nature. There were no significant transfers between level 1 and 2 during the year. Level 1 Level 2 Level 3 Total At 31 December 2022 Financial liabilities at fair value through profit or loss Debt securities and other liabilities designated at fair value through profit or loss – 5,133 45 5,178 Trading liabilities: Liabilities in respect of securities sold under repurchase agreements – 11,037 – 11,037 Short positions in securities 1,505 35 – 1,540 1,505 11,072 – 12,577 Total financial liabilities carried at fair value, excluding derivatives 1,505 16,205 45 17,755 At 31 December 2021 Financial liabilities at fair value through profit or loss Debt securities in issue designated at fair value through profit or loss – 6,504 37 6,541 Trading liabilities: Liabilities in respect of securities sold under repurchase agreements – 14,962 – 14,962 Short positions in securities 1,569 51 – 1,620 1,569 15,013 – 16,582 Total financial liabilities carried at fair value, excluding derivatives 1,569 21,517 37 23,123 The Group’s non-participating investment contracts (see note 33) were all categorised as level 2. Movements in level 3 portfolio The table below analyses movements in the level 3 financial liabilities portfolio, excluding derivatives. 2022 £m 2021 £m At 1 January 37 45 Gains recognised in the income statement within other income (4) (5) Additions 33 4 Redemptions (3) (7) Transfers out of the level 3 portfolio (18) – At 31 December 45 37 Gains recognised in the income statement, within other income, relating to the change in fair value of those liabilities held at 31 December (4) (4) Valuation methodology for financial liabilities, excluding derivatives Liabilities held at fair value through profit or loss These principally comprise debt securities in issue which are classified as level 2 and their fair value is determined using techniques whose inputs are based on observable market data. The carrying amount of the securities is adjusted to reflect the effect of changes in own credit spreads and the resulting gain or loss is recognised in other comprehensive income. In the year ended 31 December 2022, the own credit adjustment arising from the fair valuation of £5,178 million (2021: £6,541 million) of the Group’s debt securities in issue designated at fair value through profit or loss resulted in a gain of £519 million (2021: loss of £86 million), before tax, recognised in other comprehensive income. Trading liabilities in respect of securities sold under repurchase agreements The fair value of these liabilities is determined using discounted cash flow techniques. The discount rates are derived from observable repurchase agreement rate curves specific to the type of security sold under the repurchase agreement. (C) Derivatives Valuation hierarchy All of the Group’s derivative assets and liabilities are carried at fair value. At 31 December 2022, such assets totalled £24,753 million (2021: £22,051 million) and liabilities totalled £24,042 million (2021: £18,060 million). The table below analyses these derivative balances by valuation methodology (level 1, 2 or 3, as described on page F- 107 ). The fair value measurement approach is recurring in nature. There were no significant transfers between level 1 and level 2 during the year. 2022 2021 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Derivative assets 78 24,122 553 24,753 44 21,114 893 22,051 Derivative liabilities (39) (23,395) (608) (24,042) (62) (17,054) (944) (18,060) Movements in level 3 portfolio The table below analyses movements in level 3 derivative assets and liabilities carried at fair value. 2022 2021 Derivative Derivative Derivative Derivative At 1 January 893 (944) 981 (1,374) Exchange and other adjustments 47 (37) (4) 4 Gains (losses) recognised in the income statement within other income 72 204 (182) 292 Purchases (additions) 48 (46) 214 (328) (Sales) redemptions (21) 38 (116) 462 Transfers out of the level 3 portfolio (486) 177 – – At 31 December 553 (608) 893 (944) Gains (losses) recognised in the income statement, within other income, relating to the change in fair value of those assets or liabilities held at 31 December 222 125 (219) 324 Valuation methodology for derivatives Where the Group’s derivative assets and liabilities are not traded on an exchange, they are valued using valuation techniques, including discounted cash flow and options pricing models, as appropriate. The types of derivatives classified as level 2 and the valuation techniques used include: • Interest rate swaps which are valued using discounted cash flow models; the most significant inputs into those models are interest rate yield curves which are developed from publicly quoted rates • Foreign exchange derivatives that do not contain options which are priced using rates available from publicly quoted sources • Credit derivatives which are valued using standard models with observable inputs, except for the items classified as level 3, which are valued using publicly available yield and credit default swap (CDS) curves • Less complex interest rate and foreign exchange option products which are valued using volatility surfaces developed from publicly available interest rate cap, interest rate swaption and other option volatilities; option volatility skew information is derived from a market standard consensus pricing service. For more complex option products, the Group calibrates its models using observable at-the-money data; where necessary, the Group adjusts for out-of-the-money positions using a market standard consensus pricing service Complex interest rate and foreign exchange products where inputs to the valuation are significant, material and unobservable are classified as level 3. Where credit protection, usually in the form of credit default swaps, has been purchased or written on asset-backed securities, the security is referred to as a negative basis asset-backed security and the resulting derivative assets or liabilities have been classified as either level 2 or level 3 according to the classification of the underlying asset-backed security. Certain unobservable inputs used to calculate CVA, FVA, and own credit adjustments, are not significant in determining the classification of the derivative and debt instruments. Consequently, these inputs do not form part of the level 3 sensitivities presented. Derivative valuation adjustments Derivative financial instruments which are carried in the balance sheet at fair value are adjusted where appropriate to reflect credit risk, market liquidity and other risks. (i) Uncollateralised derivative valuation adjustments The following table summarises the movement on this valuation adjustment account during 2021 and 2022: 2022 £m 2021 £m At 1 January 456 474 Income statement credit (75) (18) At 31 December 381 456 Represented by: 2022 £m 2021 £m Credit Valuation Adjustment 294 306 Debit Valuation Adjustment (55) (26) Funding Valuation Adjustment 142 176 381 456 Credit and Debit Valuation Adjustments (CVA and DVA) are applied to the Group’s over-the-counter derivative exposures with counterparties that are not subject to strong interbank collateral arrangements. These exposures largely relate to the provision of risk management solutions for corporate customers within the Commercial Banking division. A CVA is taken where the Group has a positive future uncollateralised exposure (asset). A DVA is taken where the Group has a negative future uncollateralised exposure (liability). These adjustments reflect interest rates and expectations of counterparty creditworthiness and the Group’s own credit spread respectively. The CVA is sensitive to: • The current size of the mark-to-market position on the uncollateralised asset • Expectations of future market volatility of the underlying asset • Expectations of counterparty creditworthiness Market Credit Default Swap (CDS) spreads are used to develop the probability of default for quoted counterparties. For unquoted counterparties, internal credit ratings and market sector CDS curves and recovery rates are used. The loss given default (LGD) is based on market recovery rates and internal credit assessments. The combination of a one-notch deterioration in the credit rating of derivative counterparties and a ten per cent increase in LGD increases the CVA by £73 million. Current market value is used to estimate the projected exposure for products not supported by the model, which are principally complex interest rate options that are traded in very low volumes. For these, the CVA is calculated on an add-on basis (although no such adjustment was required at 31 December 2022). The DVA is sensitive to: • The current size of the mark-to-market position on the uncollateralised liability • Expectations of future market volatility of the underlying liability • The Group’s own CDS spread A one per cent rise in the CDS spread would lead to an increase in the DVA of £109 million. The risk exposures that are used for the CVA and DVA calculations are strongly influenced by interest rates. Due to the nature of the Group’s business the CVA/DVA exposures tend to be on average the same way around such that the valuation adjustments fall when interest rates rise. A one per cent rise in interest rates would lead to a £51 million fall in the overall valuation adjustment to £188 million. The CVA model used by the Group does not assume any correlation between the level of interest rates and default rates. The Group has also recognised a Funding Valuation Adjustment to adjust for the net cost of funding uncollateralised derivative positions. This adjustment is calculated on the expected future exposure discounted at a suitable cost of funds. A ten basis points increase in the cost of funds will increase the funding valuation adjustment by £13 million. (ii) Market liquidity The Group includes mid to bid-offer valuation adjustments against the expected cost of closing out the net market risk in the Group’s trading positions within a time frame that is consistent with historical trading activity and spreads that the trading desks have accessed historically during the ordinary course of business in normal market conditions. At 31 December 2022, the Group’s derivative trading business held mid to bid-offer valuation adjustments of £61 million (2021: £63 million).

The earnings multiples used are derived from those of listed entities operating in the same sector with adjustments made for factors such as the size of the company and the quality of its earnings. The majority of the Group’s venture capital investments are valued using an estimate of the company’s maintainable earnings before interest, tax, depreciation and amortisation and in accordance with the International Private Equity and Venture Capital Valuation Guidelines. A higher earnings multiple will result in a higher fair value Reasonably possible alternative assumptions Valuation techniques applied to many of the Group’s level 3 instruments often involve the use of two or more inputs whose relationship is interdependent. The calculation of the effect of reasonably possible alternative assumptions included in the table above reflects such relationships. Debt securities Reasonably possible alternative assumptions have been determined in respect of the Group’s structured credit investments by flexing credit spreads. Derivatives Reasonably possible alternative assumptions have been determined in respect of swaptions in the Group’s derivative portfolios which are priced using industry standard option pricing models. Such models require interest rate volatilities which may be unobservable at longer maturities. To derive reasonably possible alternative valuations these volatilities have been flexed within a range of 17 per cent to 105 per cent (2021: 13 per cent to 168 per cent). Unlisted equity, venture capital investments and investments in property partnerships The valuation techniques used for unlisted equity and venture capital investments vary depending on

Disclosure of transferred financial assets that are not derecognised in their entirety [Abstract]
TRANSFERS OF FINANCIAL ASSETS	NOTE 50: TRANSFERS OF FINANCIAL ASSETS There were no significant transferred financial assets which were derecognised in their entirety, but with ongoing exposure. Details of transferred financial assets that continue to be recognised in full are as follows. The Group enters into repurchase and securities lending transactions in the normal course of business that do not result in derecognition of the financial assets as substantially all of the risks and rewards, including credit, interest rate, prepayment and other price risks are retained by the Group. In all cases, the transferee has the right to sell or repledge the assets concerned. As set out in note 30, included within financial assets measured at amortised cost are loans transferred under the Group’s securitisation and covered bond programmes. As the Group retains all or a majority of the risks and rewards associated with these loans, including credit, interest rate, prepayment and liquidity risk, they remain on the Group’s balance sheet. Assets transferred into the Group’s securitisation and covered bond programmes are not available to be used by the Group while the assets are within the programmes. However, the Group retains the right to remove loans from the covered bond programmes where they are in excess of the programme’s requirements. In addition, where the Group has retained some of the notes issued by securitisation and covered bond programmes, the Group has the ability to sell or pledge these retained notes. The table below sets out the carrying values of the transferred assets and the associated liabilities. For repurchase and securities lending transactions, the associated liabilities represent the Group’s obligation to repurchase the transferred assets. For securitisation programmes, the associated liabilities represent the external notes in issue (note 30). The liabilities shown in the table below have recourse to the transferred assets. 2022 2021 Carrying Carrying Carrying Carrying Repurchase and securities lending transactions Financial assets at fair value through profit or loss 6,370 1,483 4,345 2,030 Financial assets at fair value through other comprehensive income 8,803 6,990 8,085 6,244 Securitisation programmes Financial assets at amortised cost: Loans and advances to customers 1 29,384 2,806 31,406 3,705 1 The carrying value of associated liabilities excludes securitisation notes held by the Group of £22,343 million (31 December 2021: £24,010 million).

Disclosure of financial risk management [Abstract]
FINANCIAL RISK MANAGEMENT	NOTE 52: FINANCIAL RISK MANAGEMENT As a bancassurer, financial instruments are fundamental to the Group’s activities and, as a consequence, the risks associated with financial instruments represent a significant component of the risks faced by the Group. The primary risks affecting the Group through its use of financial instruments are: market risk, which includes interest rate risk and foreign exchange risk; credit risk; liquidity risk; capital risk; and insurance risk. The following disclosures provide quantitative and qualitative information about the Group’s exposure to these risks. Market risk (A) Interest rate risk Interest rate risk arises from the different repricing characteristics of the Group’s assets and liabilities. Liabilities are generally either insensitive to interest rate movements, for example interest free or very low interest customer deposits, or are sensitive to interest rate changes but bear rates which may be varied at the Group’s discretion and that for competitive reasons generally reflect changes in the UK Bank Rate, set by the Bank of England. The rates on the remaining liabilities are contractually fixed for their term to maturity. Many banking assets are sensitive to interest rate movements; there is a large volume of managed rate assets such as variable rate mortgages which may be considered as a natural offset to the interest rate risk arising from the managed rate liabilities. However, a significant proportion of the Group’s lending assets, for example many personal loans and mortgages, bear interest rates which are contractually fixed. Interest rate sensitivity analysis relating to the Group’s Banking activities is set out in the tables marked audited on page 93 The Group’s risk management policy is to optimise reward while managing its market risk exposures within the risk appetite defined by the Board. The largest residual risk exposure arises from balances that are deemed to be insensitive to changes in market rates (including current accounts, a portion of variable rate deposits and investable equity), and is managed through the Group’s structural hedge. The structural hedge consists of longer-term fixed rate assets or interest rate swaps and the amount and duration of the hedging activity is reviewed regularly by the Group Asset and Liability Committee. The Group establishes hedge accounting relationships for interest rate risk components using cash flow hedges and fair value hedges. The Group is exposed to cash flow interest rate risk on its variable rate loans and deposits together with its floating rate subordinated debt. The derivatives used to manage the structural hedge may be designated into cash flow hedges to manage income statement volatility. The economic items related to the structural hedge, for example current accounts, are not eligible hedged items under IAS 39 for inclusion into accounting hedge relationships. The Group is exposed to fair value interest rate risk on its fixed rate customer loans, its fixed rate customer deposits and the majority of its subordinated debt, and to cash flow interest rate risk on its variable rate loans and deposits together with its floating rate subordinated debt. The Group applies netting between similar risks before applying hedge accounting. Hedge ineffectiveness arises during the management of interest rate risk due to residual unhedged risk. Sources of ineffectiveness, which the Group may decide to not fully mitigate, can include basis differences, timing differences and notional amount differences. The effectiveness of accounting hedge relationships is assessed between the hedging derivatives and the documented hedged item, which can differ to the underlying economically hedged item. At 31 December 2022 the aggregate notional principal of interest rate and other swaps (predominantly interest rate) designated as fair value hedges was £152,662 million (2021: £172,695 million) with a net fair value liability of £493 million (2021: liability of £262 million) (note 17). The gains on the hedging instruments were £1,284 million (2021: gains of £944 million). The losses on the hedged items attributable to the hedged risk were £1,325 million (2021: losses of £767 million). The gains and losses relating to the fair value hedges are recorded in net trading income. The notional principal of the interest rate swaps designated as cash flow hedges at 31 December 2022 was £249,703 million (2021: £109,093 million) with a net fair value liability of £2 million (2021: asset of £5 million) (note 17). In 2022, ineffectiveness recognised in the income statement that arises from cash flow hedges was a loss of £10 million (2021: loss of £69 million). Interest rate benchmark reform The Group continues to manage the transition to alternative benchmark rates under its Group-wide IBOR transition programme. The Group has transitioned substantially all of its non-USD LIBOR products and continues to work with customers to transition a small number of remaining contracts that either have yet to transition or have defaulted to the relevant synthetic LIBOR benchmark in the interim. USD LIBOR transition is expected to complete by 30 June 2023. While the volume of outstanding transactions impacted by IBOR benchmark reforms continues to reduce, the Group does not expect material changes to its risk management approach. The material risks identified include the following: Conduct and litigation risk. The Group may be exposed to conduct and litigation charges as a direct result of inappropriate or negligent actions taken during IBOR transition resulting in detriment to the customer. The Group is working closely with its counterparties to avoid this outcome. Market risk. IBOR transition is expected to lead to changes in the Group’s market risk profile which will continue to be monitored and managed within the appropriate risk appetites. The key change is expected to be on the management of basis risk profile during the period when alternative benchmark rates are referenced in contracts up to the cessation of the in-scope IBOR index. Credit risk. Clients may wish to renegotiate the terms of existing transactions as a consequence of IBOR reform. This could lead to a change in the credit risk exposure of the client depending on the outcome of the negotiations. The Group will continue to monitor and manage changes within the appropriate risk appetites. Accounting risk. If IBOR transition is finalised in a manner that does not permit the application of the reliefs introduced in the IFRS Phase 2 amendments, the financial instrument may be required to be derecognised and a new instrument recognised. In addition, where instruments used in hedge accounting relationships are transitioned either at different times or to different benchmarks, this may result in additional volatility to the income statement either through hedge accounting ineffectiveness or failure of the hedge accounting relationships. Operational risk. Additional operational risks may arise due to the IBOR transition programme impacting all businesses and functions within the Group and leading to the implementation of changes to technology, operations, client communication and the valuation of in-scope financial instruments. The majority of the Group’s USD LIBOR exposures are expected to transition through industry-led transition programmes managed by the London Clearing House and Futures exchanges, or through the International Swaps and Derivatives Association (ISDA) protocol. Other contracts (primarily loans) maturing after June 2023 are being managed through the Group’s existing processes, either transitioning to an alternative benchmark rate or allowed to fallback under existing contract protocols or through US legislation. At 31 December 2022, the Group had the following significant exposures impacted by interest rate benchmark reform which had yet to transition to the replacement benchmark rate: At 31 December 2022 At 31 December 2021 GBP USD Other 1 £m Total GBP USD Other Total Non-derivative financial assets Financial assets at fair value through profit or loss 106 36 – 142 1,753 268 – 2,021 Loans and advances to banks – 67 – 67 – 4,106 – 4,106 Loans and advances to customers 762 1,077 43 1,882 3,542 5,975 – 9,517 Debt securities – – – – 126 – – 126 Financial assets at amortised cost 762 1,144 43 1,949 3,668 10,081 – 13,749 Financial assets at fair value through other comprehensive income – – – – 16 – – 16 868 1,180 43 2,091 5,437 10,349 – 15,786 Non-derivative financial liabilities Customer deposits – 84 – 84 – 74 – 74 Financial liabilities at fair value through profit or loss – 100 – 100 – 100 3 103 Debt securities in issue – 52 – 52 – 54 26 80 – 236 – 236 – 228 29 257 Derivative notional/contract amount Interest rate 840 193,228 1,223 195,291 12,734 286,921 – 299,655 Cross currency – 29,452 1,124 30,576 – 42,229 – 42,229 840 222,680 2,347 225,867 12,734 329,150 – 341,884 1 Balances within Other include Canadian Dollar Offered Rate for which a cessation announcement, effective after 28 June 2024, was published on 16 May 2022. As at 31 December 2022, the IBOR balances in the above table relate to contracts that have not transitioned to an alternative benchmark rate. In the case of Sterling LIBOR, these are contracts that have cash flows determined on a synthetic LIBOR basis. Of the £222,680 million of USD derivative notional balances as at 31 December 2022, £55,973 million relate to contracts with their final LIBOR fixing prior to LIBOR cessation and £129,442 million relate to exchange traded futures or contracts settled through the London Clearing House. Of the remaining £37,265 million, £36,872 million are fallback-eligible. In respect of the Group’s hedge accounting relationships, for the purposes of determining whether: • A forecast transaction is highly probable • Hedged future cash flows are expected to occur • A hedge is expected to be highly effective in achieving offsetting changes in fair value or cash flows attributable to the hedged risk • An accounting hedging relationship should be discontinued because of a failure of the retrospective effectiveness test the Group considers the interest rate benchmark, on which the hedged risk or the cash flows of the hedged item or hedging instrument are based is not altered by uncertainties resulting from interest rate benchmark reform. • The notional amount of the hedged items that the Group has designated into cash flow hedge relationships that is directly affected by the interest rate benchmark reform is £1,771 million (2021: £3,258 million). These are principally loans and advances to customers in Commercial Banking. • The interest rate benchmark reforms also affect assets and liabilities designated in fair value hedges. At 31 December 2022, these assets had a notional value of £1,864 million and liabilities had a notional value of £17,540 million. At 31 December 2021, such assets had a notional value of £3,370 million and liabilities had a notional value of £22,437 million. These fair value hedges principally relate to debt securities in issue. • At 31 December 2022, the notional amount of the hedging instruments in hedging relationships to which these amendments apply was £19,755 million, of which £17,926 million relates to fair value hedges and £1,829 million relates to cash flow hedges. At 31 December 2021, the notional amount of the hedging instruments in hedging relationships to which these amendments applied was £27,873 million, of which £24,615 million related to fair value hedges and £3,258 million related to cash flow hedges. (B) Foreign exchange risk The corporate and retail businesses incur foreign exchange risk in the course of providing services to their customers. All non-structural foreign exchange exposures in the non-trading book are managed centrally within allocated exposure limits. Trading book exposures in the authorised trading centres are allocated exposure limits. The limits are monitored daily by the local centres and reported to the market and liquidity risk function in London. Associated VaR and the closing, average, maximum and minimum are disclosed in the tables marked audited on page 95 Risk arises from the Group’s investments in its overseas operations. The Group’s structural foreign currency exposure is represented by the net asset value of the foreign currency equity and subordinated debt investments in its subsidiaries and branches. Gains or losses on structural foreign currency exposures are taken to reserves. The Group ceased all hedge accounting of the currency translation risk of the net investment in foreign operations in 2018. The Group’s main overseas operations are in the Americas and Europe. Details of the Group’s structural foreign currency exposures are as follows: 2022 2021 Foreign currency of Group operations Euro US Dollar Other Euro US Dollar Other Exposure 1,843 209 5 115 134 7 Credit risk The Group’s credit risk exposure arises in respect of the instruments below and predominantly in the United Kingdom. Credit risk appetite is set at Board level and is described and reported through a suite of metrics devised from a combination of accounting and credit portfolio performance measures, which include the use of various credit risk rating systems as inputs and assess credit risk at a counterparty level using three components: (i) the probability of default by the counterparty on its contractual obligations; (ii) the current exposures to the counterparty and their likely future development, from which the Group derives the exposure at default; and (iii) the likely loss ratio on the defaulted obligations, the loss given default. The Group uses a range of approaches to mitigate credit risk, including internal control policies, obtaining collateral, using master netting agreements and other credit risk transfers, such as asset sales and credit derivatives based transactions. (A) Maximum credit exposure The maximum credit risk exposure of the Group in the event of other parties failing to perform their obligations is detailed below. No account is taken of any collateral held and the maximum exposure to loss, which includes amounts held to cover unit-linked and With Profits Funds liabilities, is considered to be the balance sheet carrying amount or, for non-derivative off-balance sheet transactions and financial guarantees, their contractual nominal amounts. 2022 2021 Maximum Offset 1 £m Net Maximum Offset 1 £m Net Financial assets at fair value through profit or loss 2,3 : Loans and advances 24,872 – 24,872 29,538 – 29,538 Debt securities, treasury and other bills 38,109 – 38,109 47,237 – 47,237 Contracts held with reinsurers 10,906 – 10,906 12,371 – 12,371 73,887 – 73,887 89,146 – 89,146 Derivative financial instruments 24,753 (12,330) 12,423 22,051 (11,600) 10,451 Financial assets at amortised cost, net 4 : Loans and advances to banks, net 4 10,632 – 10,632 7,001 – 7,001 Loans and advances to customers, net 4 454,899 (2,171) 452,728 448,567 (1,506) 447,061 Reverse repurchase agreements, net 4 44,865 – 44,865 54,753 – 54,753 Debt securities, net 4 9,926 – 9,926 6,835 – 6,835 520,322 (2,171) 518,151 517,156 (1,506) 515,650 Financial assets at fair value through other comprehensive income 2 22,871 – 22,871 27,902 – 27,902 Reinsurance assets 616 – 616 759 – 759 Off-balance sheet items: Acceptances and endorsements 58 – 58 191 – 191 Other items serving as direct credit substitutes 781 – 781 510 – 510 Performance bonds, including letters of credit, and other transaction-related contingencies 2,147 – 2,147 2,043 – 2,043 Irrevocable commitments and guarantees 74,692 – 74,692 71,158 – 71,158 77,678 – 77,678 73,902 – 73,902 720,127 (14,501) 705,626 730,916 (13,106) 717,810 1 Offset items comprise deposit amounts available for offset and amounts available for offset under master netting arrangements that do not meet the criteria under IAS 32 to enable loans and advances and derivative assets respectively to be presented net of these balances in the financial statements. 2 Excluding equity shares. 3 Includes assets within the Group’s unit-linked funds for which credit risk is borne by the policyholders and assets within the Group’s With-Profits Funds for which credit risk is largely borne by the policyholders. Consequently, the Group has no significant exposure to credit risk for such assets which back related contract liabilities. 4 Amounts shown net of related impairment allowances. (B) Concentrations of exposure The Group’s management of concentration risk includes portfolio controls on certain industries, sectors and products to reflect risk appetite as well as individual, customer and bank limit risk tolerances. Credit policies and appetite statements are aligned to the Group’s risk appetite and restrict exposure to higher risk countries and potentially vulnerable sectors and asset classes. Exposures are monitored to prevent both an excessive concentration of risk and single name concentrations. The Group’s largest credit limits are regularly monitored by the Board Risk Committee and reported in accordance with regulatory requirements. As part of its credit risk policy, the Group considers sustainability risk (which incorporates Environmental (including climate), Social and Governance) in the assessment of Commercial Banking facilities. At 31 December 2022 the most significant concentrations of exposure were in mortgages (comprising 71 per cent of total loans and advances to customers) and to financial, business and other services (comprising 8 per cent of the total). 2022 £m 2021 £m Agriculture, forestry and fishing 7,447 7,729 Energy and water supply 2,552 1,978 Manufacturing 3,619 4,110 Construction 4,066 4,440 Transport, distribution and hotels 13,170 13,463 Postal and telecommunications 2,526 2,109 Property companies 21,499 23,923 Financial, business and other services 37,666 33,533 Personal: Mortgages 1 323,923 319,655 Other 26,154 24,604 Lease financing 766 982 Hire purchase 16,029 15,861 Total loans and advances to customers before allowance for impairment losses 459,417 452,387 Allowance for impairment losses (note 18) (4,518) (3,820) Total loans and advances to customers 454,899 448,567 1 Includes both UK and overseas mortgage balances. The Group’s operations are predominantly UK-based and as a result an analysis of credit risk exposures by geographical region is not provided. (C) Credit quality of assets Loans and advances The analysis of lending has been prepared based on the division in which the asset is held; with the business segment in which the exposure is recorded reflected in the ratings system applied. The internal credit ratings systems used by the Group differ between Retail and Commercial, reflecting the characteristics of these exposures and the way that they are managed internally; these credit ratings are set out below. All probabilities of default (PDs) include forward-looking information and are based on 12-month values, with the exception of credit-impaired.

Event After Reporting Period [Abstract]
EVENTS SINCE THE BALANCE SHEET DATE	NOTE 54: EVENTS SINCE THE BALANCE SHEET DATE Acquisition of Tusker On 21 February 2023, Lloyds Bank Asset Finance Limited, a wholly-owned subsidiary of the Group, acquired 100 per cent of the ordinary share capital of Hamsard 3352 Limited (“Tusker”), which together with its subsidiaries operates a vehicle management and leasing business. The acquisition will enable the Group to expand its salary sacrifice proposition within motor finance. Cash consideration was approximately £300 million 1 . As a result of the limited time available between the acquisition and the approval of these financial statements, the Group is still in the process of finalising the fair value of the individual assets and liabilities acquired including the associated identifiable intangible assets and goodwill. 1 Subject to customary adjustments. Share buyback The Board has announced its intention to implement an ordinary share buyback of up to £2.0 billion. This represents the return to shareholders of capital surplus to that required to provide capacity to grow the business, meet current and future regulatory requirements and cover uncertainties. The share buyback programme will commence as soon as is practicable and is expected to be completed, subject to continued authority from the PRA, by 31 December 2023.

Disclosure of expected impact of initial application of new standards or interpretations [Abstract]
FUTURE ACCOUNTING DEVELOPMENTS	NOTE 55: FUTURE ACCOUNTING DEVELOPMENTS The following pronouncements are not applicable for the year ending 31 December 2022 and have not been applied in preparing these financial statements. Save as disclosed below, the impact of these accounting changes is still being assessed by the Group and reliable estimates cannot be made at this stage. IFRS 17 Insurance Contracts IFRS 17 Insurance Contracts replaces IFRS 4 Insurance Contracts and is effective for annual periods beginning on or after 1 January 2023. The Group’s initial application date was 1 January 2023 and its transition date was 1 January 2022. On transition, the Group will use the full retrospective approach for business written since 1 January 2016 using Solvency II modelling tools developed when Solvency II was implemented, which are only available to support the calculation of IFRS 17 results from that date. The fair value approach will be used for business written prior to 1 January 2016 and valuations supporting Solvency II at the transition date will be used to support the fair value calculation for transition for that business. Comparative information As permitted by IFRS 17, the Group’s financial statements at and for the year ended 31 December 2023 will include restated comparatives for the year ended 31 December 2022 only. Comparative information for the year ended 31 December 2021 will be presented in accordance with IFRS 4. IFRS 17 recognition and measurement IFRS 17 requires insurance contracts, including reinsurance contracts, and investment contracts with discretionary participation features to be recognised on the balance sheet as the total of the fulfilment cash flows and the contractual service margin: • The fulfilment cash flows consist of the present value of future cash flows calculated using best estimate assumptions, together with an explicit risk adjustment for non-financial risk and are required to be remeasured at each reporting date • The contractual service margin (CSM) represents the unearned profit on the insurance contracts and investment contracts with discretionary participation features Changes to estimates of fulfilment cash flows which relate to future service are taken to the CSM, except where onerous contracts are identified or where the Group takes advantage of the risk mitigation options available under IFRS 17. The Group calculates the risk adjustment by applying margins to best estimate cashflows relating to non-financial risks (such as mortality or persistency). The risk adjustment will be released to the income statement as risk expires. For reinsurance contracts held, the CSM represents the net cost or net gain of purchasing reinsurance and the risk adjustment represents the amount of risk transferred from the underlying contracts held. Expected impact: comparison with IFRS 4 Under IFRS 4, the Group recognises a value in-force asset and the expected profit of an insurance contract at its inception. Under IFRS 17, the expected profit for providing insurance contract services will be recognised in the CSM and released to the income statement throughout the contract period over which the insurance contract services are provided. The risk adjustment is released commensurate with the expiry of non-financial risk associated with the valuation of best estimate cash flows. The value in-force asset recognised by the Group at 31 December 2021 will be derecognised on transition. IFRS 17 will impact the timing of profit recognition for the insurance contracts and investment contracts with discretionary participation features issued by the Group. However, it will not change the total profit recognised over the lifetime of these contracts as compared to IFRS 4, or the capital position or cash flows of the Group and its insurance companies. The change in the measurement basis of the Group’s liabilities, the derecognition of the VIF and the recognition, within the CSM, of a proportion of the previously recognised profits from insurance contracts will result in a reduction to the Group’s retained earnings on transition. Establishing cash flows within the boundary of an insurance contract IFRS 17 requires cash flows to be included within the boundary of an insurance contract if they arise from substantive rights and obligations that exist during the reporting period where the Group can compel a policyholder to pay premiums or where the Group has a substantive obligation to provide the policyholder with services. The Group has assessed the contract boundary for insurance contracts it sells and has established relevant fulfilment cash flows accordingly, and the assumption framework which applies to determining the best estimate of those cash flows on an on-going basis. In particular, this includes the assumptions around increments on pensions business which are expected within the contract boundary and the extent to which the contract boundary is substantially changed upon contact modification as a result of new product features being added. Level of aggregation of insurance contracts IFRS 17 requires identification of portfolios of insurance contracts that have similar risks and that are managed together. In determining the appropriate level of aggregation, the Group has considered the relative risks and how these are managed within the business, in addition to factors such as geography, sales channel and product taxation basis. CSM is measured on initial recognition for cohorts of insurance contracts within these portfolios that are issued not more than a year apart. These cohorts are further disaggregated into CSM groups according to a profitability assessment and other product characteristics. As a result, the Group has identified the following portfolios: individual annuities, bulk annuities, protection products and workplace and other pensions. Within these portfolios, the Group expects to have approximately 25 CSM groups during 2023, in addition to those established at transition to IFRS 17. Separating components of contracts IFRS 17 also requires certain components of insurance contracts to be separated, including investment components. Investment components reflect amounts due to policy holders, akin to deposits, so are not recognised in the income statement. Disaggregation of insurance finance income or expenses Insurance finance income or expenses comprise changes in the carrying amount of a group of insurance contracts arising from the effect of the time value of money and the effects of financial risk. IFRS 17 provides an accounting policy choice between: • including insurance finance income or expenses for the period in the income statement; or • disaggregating insurance finance income and expenses for the period to include in the income statement an amount determined by a systematic allocation, and the residual amount in other comprehensive income (OCI). The Group has elected to recognise total insurance finance income or expenses in profit or loss in the period in which they arise. This decision is based on IFRS 9 Financial Instruments . Under IFRS 9, the Group measures assets backing insurance contracts at fair value through profit or loss (FVTPL). Accounting for the Group’s principal insurance businesses Annuity and protection business: The general measurement model will be used for the Group’s annuity and protection business. The discount rates are locked in at the inception of the contract in determining the value of the CSM. The subsequent effects of changes in discount rates on the best estimate of the insurance contract liabilities will be recognised in the income statement in the period in which they arise, as an accounting policy choice. The Group will use discount rates based on the liquidity of the associated liabilities and, accordingly, will apply illiquidity premia to its annuity and whole of life businesses. For immediate annuity contracts, the CSM will be recognised in income over the life of the contracts based on the maximum claim payable for each period and for protection contracts, CSM will be recognised in the income statement commensurate with the sum assured. Unit-linked and with-profits business: There is an adaptation of the general measurement model for contracts with direct participation features, the variable fee approach, which results in changes in variable fees, including those arising from changes in economic assumptions, being taken to the CSM. The expected profit will be recognised within the CSM and released to the income statement over the coverage period. General insurance business: The Group has applied the option available under IFRS 17 to use the simplified approach (the premium allocation approach), mainly for short duration contracts. The insurance revenue recognised in the income statement in the period reflects the expected premium receipts allocated to the period, after adjusting for the time value of money and the effect of financial risk. The amortisation of insurance acquisition cash flows is taken to the income statement on the basis of the passage of time. Balance sheet impact at 1 January 2022 On restatement, the reduction in the Group’s total equity as of 1 January 2022 was approximately £1.9 billion, driven by the derecognition of the value in-force asset, the move to best estimate of contract liabilities, the creation of the new CSM liability and the establishment of the risk adjustment. The CSM of all insurance contracts issued and net of reinsurance contracts held at 1 January 2022 was approximately £1.9 billion and the risk adjustment, net of reinsurance, recognised at that date was approximately £1.5 billion. The Group expects that approximately £300 million of the CSM and risk adjustment, gross of reinsurance, held at 1 January 2022 will be released and recognised in the income statement during the year ended 31 December 2022. These amounts will be finalised during the first quarter of 2023 following the completion of further work being undertaken by the Group. Equity impact at 31 December 2022 During 2022, the Group has added a drawdown feature to its existing longstanding and workplace pension business. This is a contract modification that results in a substantially different contract boundary, and IFRS 17 requires that the contracts and associated CSM (approximately £0.4 billion) at the time of the modification are derecognised and the modified contracts together with a new CSM (approximately £1.7 billion) are recognised as if they were new contracts. The Group estimates these contract modifications will increase the CSM by approximately £1.3 billion and reduce its equity by approximately £1.3 billion (before the impact of IFRS 17 tax transitional adjustments) given the charge recognised in the income statement in 2022 on an IFRS 17 basis. The estimate has been prepared assuming these contract modifications occurred on the 1 January 2022. As these contract modifications occurred throughout 2022, the Group will undertake further work during the first quarter of 2023 to finalise the financial impact of the contract modifications using the actual dates these contract modifications occurred during 2022. Income statement impact Whilst IFRS 17 does not change the total profit recognised over the life of an insurance contract or investment contract with discretionary participation features, it does change both the phasing of profit recognition and the amounts recognised within individual income statement line items, including other income and operating expenses. Under IFRS 17, the Group is required to defer substantially all of the expected profit through the recognition of a CSM on the balance sheet (losses on groups of onerous contracts and recoveries of such losses, to the extent they are covered by reinsurance contracts held, are recognised in the income statement immediately); the CSM is subsequently released to the income statement over the coverage period of the product. The expected profit includes estimated future premiums and claims together with administration costs such as claims handling costs, costs incurred to provide contractual policyholder benefits and policy administration and maintenance costs. As a result, a reduction is expected in the amounts to be disclosed as other income, operating income and operating expenses under IFRS 17, in respect of the relevant IFRS 17 income statement line items that will be presented from 2023. The Group continues to refine and finalise the new accounting processes and models and has not, therefore, presented the impact of IFRS 17 for the year ended 31 December 2022 including impacts on financial metrics such as earnings per share. Further work will be undertaken during the first quarter of 2023 to finalise the impact of IFRS 17 on the Group’s income statement and earnings per share for the year ended 31 December 2022 and on its balance sheet at 31 December 2022. Minor amendments to other accounting standards The IASB has issued a number of minor amendments to IFRSs effective 1 January 2023 (including IAS 1 Presentation of Financial Statements and IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors ). These amendments are not expected to have a significant impact on the Group.

Disclosure of significant accounting policies [Abstract]
Consolidation	The assets, liabilities and results of Group undertakings (including structured entities) are included in the financial statements on the basis of accounts made up to the reporting date. Group undertakings include subsidiaries, associates and joint ventures. (1) Subsidiaries Subsidiaries are entities controlled by the Group. The Group controls an entity when it has power over the entity, is exposed to, or has rights to, variable returns from its involvement with the entity, and has the ability to affect those returns through the exercise of its power. This generally accompanies a shareholding of more than one half of the voting rights although in certain circumstances a holding of less than one half of the voting rights may still result in the ability of the Group to exercise control. The existence and effect of potential voting rights that are currently exercisable or convertible are considered when assessing whether the Group controls another entity. The Group reassesses whether or not it controls an entity if facts and circumstances indicate that there have been changes to any of the above elements. Subsidiaries are fully consolidated from the date on which control is transferred to the Group; they are de-consolidated from the date that control ceases. The Group consolidates collective investment vehicles if its beneficial ownership interests give it substantive rights to remove the external fund manager of the investment activities of the fund. Where a subsidiary of the Group is the fund manager of a collective investment vehicle, the Group considers a number of factors in determining whether it acts as principal, and therefore controls the collective investment vehicle, including: an assessment of the scope of the Group’s decision-making authority over the investment vehicle; the rights held by other parties including substantive removal rights without cause over the Group acting as fund manager; the remuneration to which the Group is entitled in its capacity as decision-maker; and the Group’s exposure to variable returns from the beneficial interest that it holds in the investment vehicle. Consolidation may be appropriate in circumstances where the Group has less than a majority beneficial interest. Where a collective investment vehicle is consolidated the interests of parties other than the Group are reported in other liabilities and the movement in those interests in interest expense. Structured entities are entities that are designed so that their activities are not governed by way of voting rights. In assessing whether the Group has power over such entities in which it has an interest, the Group considers factors such as the purpose and design of the entity; its practical ability to direct the relevant activities of the entity; the nature of the relationship with the entity; and the size of its exposure to the variability of returns of the entity. The treatment of transactions with non-controlling interests depends on whether, as a result of the transaction, the Group loses control of the subsidiary. Changes in the parent’s ownership interest in a subsidiary that do not result in a loss of control are accounted for as equity transactions; any difference between the amount by which the non-controlling interests are adjusted and the fair value of the consideration paid or received is recognised directly in equity and attributed to the owners of the parent entity. Where the Group loses control of the subsidiary, at the date when control is lost the amount of any non-controlling interest in that former subsidiary is derecognised and any investment retained in the former subsidiary is remeasured to its fair value; the gain or loss that is recognised in profit or loss on the partial disposal of the subsidiary includes the gain or loss on the remeasurement of the retained interest. Intercompany transactions, balances and unrealised gains and losses on transactions between Group companies are eliminated. The acquisition method of accounting is used to account for business combinations by the Group. The consideration for the acquisition of a subsidiary is the fair value of the assets transferred, the liabilities incurred and the equity interests issued by the Group. The consideration includes the fair value of any asset or liability resulting from a contingent consideration arrangement. Acquisition-related costs are expensed as incurred except those relating to the issuance of debt instruments (see (E)(4) below) or share capital (see (P) below). Identifiable assets acquired and liabilities assumed in a business combination are measured initially at their fair value at the acquisition date. (2) Joint ventures and associates Joint ventures are joint arrangements over which the Group has joint control with other parties and has rights to the net assets of the arrangements. Joint control is the contractually agreed sharing of control of an arrangement and only exists when decisions about the relevant activities require the unanimous consent of the parties sharing control. Associates are entities over which the Group has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the entity, but is not control or joint control of those policies, and is generally achieved through holding between 20 per cent and 50 per cent of the voting share capital of the entity. The Group utilises the venture capital exemption for investments where significant influence or joint control is present and the business unit operates as a venture capital business. These investments are designated on initial recognition at fair value through profit or loss. Otherwise, the Group’s investments in joint ventures and associates are accounted for using the equity method of accounting.
Goodwill	Goodwill arises on business combinations and represents the excess of the cost of an acquisition over the fair value of the Group’s share of the identifiable assets, liabilities and contingent liabilities acquired. Where the fair value of the Group’s share of the identifiable assets, liabilities and contingent liabilities of the acquired entity is greater than the cost of acquisition, the excess is recognised immediately in the income statement. Goodwill is recognised as an asset at cost and is tested at least annually for impairment. For impairment testing, goodwill is allocated to the cash generating unit (CGU) or groups of CGUs that are expected to benefit from the business combination. The Group's CGUs are largely product based for its Retail and Insurance businesses and client based for its Commercial Banking business. An impairment loss is recognised if the carrying amount of a CGU is determined to be greater than its recoverable amount. The recoverable amount of a CGU is the higher of its fair value less costs to sell and its value in use. If an impairment is identified the carrying value of the goodwill is written down immediately through the income statement and this is not subsequently reversed. At the date of disposal of a subsidiary, the carrying value of attributable goodwill is included in the calculation of the profit or loss on disposal.
Other intangible assets	Intangible assets which have been determined to have a finite useful life are amortised on a straight-line basis over their estimated useful life as follows: up to 7 years for capitalised software; 10 to 15 years for brands and other intangible assets. Intangible assets with finite useful lives are reviewed at each reporting date to assess whether there is any indication that they are impaired. If any such indication exists the recoverable amount of the asset is determined and in the event that the asset’s carrying amount is greater than its recoverable amount, it is written down immediately. Certain brands have been determined to have an indefinite useful life and are not amortised. Such intangible assets are assessed annually to determine whether the asset is impaired and to reconfirm that an indefinite useful life remains appropriate. In the event that an indefinite life is inappropriate, a finite life is determined and a further impairment review is performed on the asset.
Revenue recognition	(1) Net interest income Interest income and expense are recognised in the income statement using the effective interest method for all interest-bearing financial instruments, except for those classified at fair value through profit or loss. The effective interest method is a method of calculating the amortised cost of a financial asset or liability and of allocating the interest income or interest expense over the expected life of the financial instrument. The effective interest rate is the rate that exactly discounts the estimated future cash payments or receipts over the expected life of the financial instrument to the gross carrying amount of the financial asset (before adjusting for expected credit losses) or to the amortised cost of the financial liability, including early redemption fees, other fees, and premiums and discounts that are an integral part of the overall return. In the case of financial assets that are purchased or originated credit-impaired, the effective interest rate is the rate that discounts the estimated future cash flows to the amortised cost of the instrument. Direct incremental transaction costs related to the acquisition, issue or disposal of a financial instrument are also taken into account. Interest income from non-credit impaired financial assets is recognised by applying the effective interest rate to the gross carrying amount of the asset; for credit impaired financial assets, the effective interest rate is applied to the net carrying amount after deducting the allowance for expected credit losses. Impairment policies are set out in (H) below. (2) Fee and commission income and expense Fees and commissions receivable which are not an integral part of the effective interest rate are recognised as income as the Group fulfils its performance obligations. The Group’s principal performance obligations arising from contracts with customers are in respect of value added current accounts, credit cards and debit cards. These fees are received, and the Group provides the service, monthly; the fees are recognised in income on this basis. The Group also receives certain fees in respect of its asset finance business where the performance obligations are typically fulfilled towards the end of the customer contract; these fees are recognised in income on this basis. Where it is unlikely that the loan commitments will be drawn, loan commitment fees are recognised in fee and commission income over the life of the facility, rather than as an adjustment to the effective interest rate for the lending expected to be drawn. Incremental costs incurred to generate fee and commission income are charged to fee and commission expense as they are incurred. (3) Other Dividend income is recognised when the right to receive payment is established. Revenue recognition policies specific to trading income are set out in (E)(3) below; those relating to life insurance and general insurance business are detailed below (see (M) below); and those relating to leases are set out in (J)(1) below.
Financial assets and liabilities	On initial recognition, financial assets are classified as measured at amortised cost, fair value through other comprehensive income or fair value through profit or loss, depending on the Group’s business model for managing those financial assets and whether the resultant cash flows represent solely payments of principal and interest. The Group assesses its business models at a portfolio level based on its objectives for the relevant portfolio, how the performance of the portfolio is managed and reported, and the frequency of asset sales. Financial assets with embedded derivatives are considered in their entirety when considering their cash flow characteristics. The Group reclassifies financial assets only when its business model for managing those assets changes. A reclassification will only take place when the change is significant to the Group’s operations and will occur at a portfolio level and not for individual instruments; reclassifications are expected to be rare. Equity investments are measured at fair value through profit or loss unless the Group elects at initial recognition to account for the instruments at fair value through other comprehensive income. For these instruments, principally strategic investments, dividends are recognised in profit or loss but fair value gains and losses are not subsequently reclassified to profit or loss following derecognition of the investment. The Group initially recognises loans and advances, deposits, debt securities in issue and subordinated liabilities when the Group becomes a party to the contractual provisions of the instrument. Regular way purchases and sales of securities and other financial assets and trading liabilities are recognised on trade date, being the date that the Group is committed to purchase or sell an asset. Financial assets are derecognised when the contractual right to receive cash flows from those assets has expired or when the Group has transferred its contractual right to receive the cash flows from the assets and either: substantially all of the risks and rewards of ownership have been transferred; or the Group has neither retained nor transferred substantially all of the risks and rewards, but has transferred control. Financial liabilities are derecognised when the obligation is discharged, cancelled or expires. (1) Financial instruments measured at amortised cost Financial assets that are held to collect contractual cash flows where those cash flows represent solely payments of principal and interest are measured at amortised cost. A basic lending arrangement results in contractual cash flows that are solely payments of principal and interest on the principal amount outstanding. Where the contractual cash flows introduce exposure to risks or volatility unrelated to a basic lending arrangement such as changes in equity prices or commodity prices, the payments do not comprise solely principal and interest. Financial assets measured at amortised cost are predominantly loans and advances to customers and banks, reverse repurchase agreements and certain debt securities used by the Group to manage its liquidity. Loans and advances and reverse repurchase agreements are initially recognised when cash is advanced to the borrower at fair value inclusive of transaction costs. Interest income is accounted for using the effective interest method (see (D) above). Financial liabilities are measured at amortised cost, except for trading liabilities and other financial liabilities designated at fair value through profit or loss on initial recognition which are held at fair value. Where changes are made to the contractual cash flows of a financial asset or financial liability that are economically equivalent and arise as a direct consequence of interest rate benchmark reform, the Group updates the effective interest rate and does not recognise an immediate gain or loss. (2) Financial assets measured at fair value through other comprehensive income Financial assets that are held to collect contractual cash flows and for subsequent sale, where the assets’ cash flows represent solely payments of principal and interest, are recognised in the balance sheet at their fair value, inclusive of transaction costs. Interest calculated using the effective interest method and foreign exchange gains and losses on assets denominated in foreign currencies are recognised in the income statement. All other gains and losses arising from changes in fair value are recognised directly in other comprehensive income, until the financial asset is either sold or matures, at which time the cumulative gain or loss previously recognised in other comprehensive income is recognised in the income statement; other than in respect of equity shares, for which the cumulative revaluation amount is transferred directly to retained profits. The Group recognises a charge for expected credit losses in the income statement (see (H) below). As the asset is measured at fair value, the charge does not adjust the carrying value of the asset, and this is reflected in other comprehensive income. (3) Financial instruments measured at fair value through profit or loss Financial assets are classified at fair value through profit or loss where they do not meet the criteria to be measured at amortised cost or fair value through other comprehensive income or where they are designated at fair value through profit or loss to reduce an accounting mismatch. All derivatives are carried at fair value through profit or loss, other than those in effective cash flow and net investment hedging relationships. Derivatives are carried on the balance sheet as assets when their fair value is positive and as liabilities when their fair value is negative. Refer to note 49(3) (Financial instruments: Financial assets and liabilities carried at fair value) for details of valuation techniques and significant inputs to valuation models. Derivatives embedded in a financial asset are not considered separately; the financial asset is considered in its entirety when determining whether its cash flows are solely payments of principal and interest. Derivatives embedded in financial liabilities and insurance contracts (unless the embedded derivative is itself an insurance contract) are treated as separate derivatives when their economic characteristics and risks are not closely related to those of the host contract and the host contract is not carried at fair value through profit or loss. These embedded derivatives are measured at fair value with changes in fair value recognised in the income statement. In accordance with IFRS 4 Insurance Contracts , a policyholder’s option to surrender an insurance contract for a fixed amount is not treated as an embedded derivative. The assets backing the insurance and investment contracts issued by the Group do not meet the criteria to be measured at amortised cost or fair value through other comprehensive income as they are managed on a fair value basis and accordingly are measured at fair value through profit or loss. Similarly, trading securities, which are debt securities and equity shares acquired principally for the purpose of selling in the short term or which are part of a portfolio which is managed for short-term gains, do not meet these criteria and are also measured at fair value through profit or loss. Financial assets measured at fair value through profit or loss are recognised in the balance sheet at their fair value. Fair value gains and losses together with interest coupons and dividend income are recognised in the income statement within net trading income. Financial liabilities are measured at fair value through profit or loss where they are trading liabilities or where they are designated at fair value through profit or loss in order to reduce an accounting mismatch; where the liabilities are part of a group of liabilities (or assets and liabilities) which is managed, and its performance evaluated, on a fair value basis; or where the liabilities contain one or more embedded derivatives that significantly modify the cash flows arising under the contract and would otherwise need to be separately accounted for. Financial liabilities measured at fair value through profit or loss are recognised in the balance sheet at their fair value. Fair value gains and losses are recognised in the income statement within net trading income in the period in which they occur, except in the case of financial liabilities designated at fair value through profit or loss where gains and losses attributable to changes in own credit risk are recognised in other comprehensive income. The fair values of assets and liabilities traded in active markets are based on current bid and offer prices, respectively, which include the expected effects of potential changes to laws and regulations, risks associated with climate change and other factors. If the market is not active the Group establishes a fair value by using valuation techniques. The fair values of derivative financial instruments are adjusted where appropriate to reflect credit risk (via credit valuation adjustments (CVAs), debit valuation adjustments (DVAs) and funding valuation adjustments (FVAs)), market liquidity and other risks. (4) Borrowings Borrowings (which include deposits from banks, customer deposits, repurchase agreements, debt securities in issue and subordinated liabilities) are recognised initially at fair value, being their issue proceeds net of transaction costs incurred. These instruments are subsequently stated at amortised cost using the effective interest method. Preference shares and other instruments which carry a mandatory coupon or are redeemable on a specific date are classified as financial liabilities. The coupon on these instruments is recognised in the income statement as interest expense. Securities which carry a discretionary coupon and have no fixed maturity or redemption date are classified as other equity instruments. Interest payments on these securities are recognised as distributions from equity in the period in which they are paid. An exchange of financial liabilities on substantially different terms is accounted for as an extinguishment of the original financial liability and the recognition of a new financial liability. The difference between the carrying amount of a financial liability extinguished and the new financial liability is recognised in profit or loss together with any related costs or fees incurred. When a financial liability is exchanged for an equity instrument, the new equity instrument is recognised at fair value and any difference between the carrying value of the liability and the fair value of the new equity instrument is recognised in profit or loss. (5) Sale and repurchase agreements (including securities lending and borrowing) Securities sold subject to repurchase agreements (repos) continue to be recognised on the balance sheet where substantially all of the risks and rewards are retained. Funds received for repos carried at fair value are included within trading liabilities. Conversely, securities purchased under agreements to resell (reverse repos), where the Group does not acquire substantially all of the risks and rewards of ownership, are measured at amortised cost or at fair value. Those measured at fair value are recognised within trading securities. The difference between sale and repurchase price is treated as interest and accrued over the life of the agreements using the effective interest method. Securities borrowing and lending transactions are typically secured; collateral takes the form of securities or cash advanced or received. Securities lent to counterparties are retained on the balance sheet. Securities borrowed are not recognised on the balance sheet, unless these are sold to third parties, in which case the obligation to return them is recorded at fair value as a trading liability. Cash collateral given or received is treated as a loan and advance measured at amortised cost or customer deposit.
Hedge accounting	As permitted by IFRS 9, the Group continues to apply the requirements of IAS 39 to its hedging relationships. Changes in the fair value of all derivative instruments, other than those in effective cash flow and net investment hedging relationships, are recognised immediately in the income statement. As noted in (2) and (3) below, the change in fair value of a derivative in an effective cash flow or net investment hedging relationship is allocated between the income statement and other comprehensive income. Hedge accounting allows one financial instrument, generally a derivative such as a swap, to be designated as a hedge of another financial instrument such as a loan or deposit or a portfolio of such instruments. At the inception of the hedge relationship, formal documentation is drawn up specifying the hedging strategy, the hedged item, the hedging instrument and the methodology that will be used to measure the effectiveness of the hedge relationship in offsetting changes in the fair value or cash flow of the hedged risk. The effectiveness of the hedging relationship is tested both at inception and throughout its life and if at any point it is concluded that it is no longer highly effective in achieving its documented objective, hedge accounting is discontinued. Note 17 provides details of the types of derivatives held by the Group and presents separately those designated in hedge relationships. Where there is uncertainty arising from interest rate benchmark reform, the Group assumes that the interest rate benchmark on which the hedged cash flows and/or the hedged risk are based, or the interest rate benchmark on which the cash flows of the hedging instrument are based, are not altered as a result of interest rate benchmark reform. The Group does not discontinue a hedging relationship during the period of uncertainty arising from the interest rate benchmark reform solely because the actual results of the hedge are not highly effective. Where the contractual terms of a financial asset, financial liability or derivative are amended, on an economically equivalent basis, as a direct consequence of interest rate benchmark reform, the uncertainty arising from the reform is no longer present. In these circumstances, the Group amends the hedge documentation to reflect the changes required by the reform; these changes to the documentation do not in and of themselves result in the discontinuation of hedge accounting or require the designation of a new hedge relationship. (1) Fair value hedges Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recorded in the income statement, together with the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk; this also applies if the hedged asset is classified as a financial asset at fair value through other comprehensive income. If the hedge no longer meets the criteria for hedge accounting, changes in the fair value of the hedged item attributable to the hedged risk are no longer recognised in the income statement. The cumulative adjustment that has been made to the carrying amount of the hedged item is amortised to the income statement using the effective interest method over the period to maturity. (2) Cash flow hedges The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognised in other comprehensive income in the cash flow hedging reserve. The gain or loss relating to the ineffective portion is recognised immediately in the income statement. Amounts accumulated in equity are reclassified to the income statement in the periods in which the hedged item affects profit or loss. When a hedging instrument expires or is sold, or when a hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss existing in equity at that time remains in equity and is recognised in the income statement when the forecast transaction is ultimately recognised in the income statement. When a forecast transaction is no longer expected to occur, the cumulative gain or loss that was reported in equity is immediately transferred to the income statement. (3) Net investment hedges Hedges of net investments in foreign operations are accounted for similarly to cash flow hedges. Any gain or loss on the hedging instrument relating to the effective portion of the hedge is recognised in other comprehensive income, the gain or loss relating to the ineffective portion is recognised immediately in the income statement. Gains and losses accumulated in equity are included in the income statement when the foreign operation is disposed of. The hedging instruments used in net investment hedges may include non-derivative liabilities as well as derivative financial instruments.
Offset	Financial assets and liabilities are offset and the net amount reported in the balance sheet when there is a legally enforceable right of offset and there is an intention to settle on a net basis, or realise the asset and settle the liability simultaneously. Cash collateral on exchange traded derivative transactions is presented gross unless the collateral cash flows are always settled net with the derivative cash flows. In certain situations, even though master netting agreements exist, the lack of management intention to settle on a net basis results in the financial assets and liabilities being reported gross on the balance sheet.
Impairment of financial assets	The impairment charge in the income statement reflects the change in expected credit losses, including those arising from fraud. Expected credit losses are recognised for loans and advances to customers and banks, other financial assets held at amortised cost, financial assets (other than equity investments) measured at fair value through other comprehensive income, and certain loan commitments and financial guarantee contracts. Expected credit losses are calculated as an unbiased and probability-weighted estimate using an appropriate probability of default, adjusted to take into account a range of possible future economic scenarios, and applying this to the estimated exposure of the Group at the point of default after taking into account the value of any collateral held, repayments, or other mitigants of loss and including the impact of discounting using the effective interest rate. At initial recognition, allowance (or provision in the case of some loan commitments and financial guarantees) is made for expected credit losses resulting from default events that are possible within the next 12 months (12-month expected credit losses). In the event of a significant increase in credit risk since origination, allowance (or provision) is made for expected credit losses resulting from all possible default events over the expected life of the financial instrument (lifetime expected credit losses). Financial assets where 12-month expected credit losses are recognised are considered to be Stage 1; financial assets which are considered to have experienced a significant increase in credit risk since initial recognition are in Stage 2; and financial assets which have defaulted or are otherwise considered to be credit-impaired are allocated to Stage 3. Some Stage 3 assets, mainly in Commercial Banking, are subject to individual rather than collective assessment. Such cases are subject to a risk-based impairment sanctioning process, and these are reviewed and updated at least quarterly, or more frequently if there is a significant change in the credit profile. The collective assessment of impairment aggregates financial instruments with similar risk characteristics, such as whether the facility is revolving in nature or secured and the type of security held against financial assets. An assessment of whether credit risk has increased significantly since initial recognition considers the change in the risk of default occurring over the remaining expected life of the financial instrument. In determining whether there has been a significant increase in credit risk, the Group uses quantitative tests based on relative and absolute probability of default (PD) movements linked to internal credit ratings together with qualitative indicators such as watchlists and other indicators of historical delinquency, credit weakness or financial difficulty. The use of internal credit ratings and qualitative indicators ensures alignment between the assessment of staging and the Group’s management of credit risk which utilises these internal metrics within distinct retail and commercial portfolio risk management practices. However, unless identified at an earlier stage, the credit risk of financial assets is deemed to have increased significantly when more than 30 days past due. The use of a payment holiday in and of itself has not been judged to indicate a significant increase in credit risk, with the underlying long-term credit risk deemed to be driven by economic conditions and captured through the use of forward-looking models. These portfolio-level models are capturing the anticipated volume of increased defaults and therefore an appropriate assessment of staging and expected credit loss. Where the credit risk subsequently improves such that it no longer represents a significant increase in credit risk since initial recognition, the asset is transferred back to Stage 1. Assets are transferred to Stage 3 when they have defaulted or are otherwise considered to be credit-impaired. Default is considered to have occurred when there is evidence that the customer is experiencing financial difficulty which is likely to affect significantly the ability to repay the amount due. IFRS 9 contains a rebuttable presumption that default occurs no later than when a payment is 90 days past due which the Group now uses for all its products following changes to the definition of default for UK Mortgages on 1 January 2022. In addition, other indicators of mortgage default are added including end-of-term payments on past due interest-only accounts and loans considered non-performing due to recent arrears or forbearance. The use of payment holidays is not considered to be an automatic trigger of regulatory default and therefore does not automatically trigger Stage 3. Days past due will also not accumulate on any accounts that have taken a payment holiday including those already past due. In certain circumstances, the Group will renegotiate the original terms of a customer’s loan, either as part of an ongoing customer relationship or in response to adverse changes in the circumstances of the borrower. In the latter circumstances, the loan will remain classified as either Stage 2 or Stage 3 until the credit risk has improved such that it no longer represents a significant increase since origination (for a return to Stage 1), or the loan is no longer credit-impaired (for a return to Stage 2). On renegotiation the gross carrying amount of the loan is recalculated as the present value of the renegotiated or modified contractual cash flows, which are discounted at the original effective interest rate. Renegotiation may also lead to the loan and associated allowance being derecognised and a new loan being recognised initially at fair value. Purchased or originated credit-impaired financial assets (POCI) include financial assets that are purchased or originated at a deep discount that reflects incurred credit losses. At initial recognition, POCI assets do not carry an impairment allowance; instead, lifetime expected credit losses are incorporated into the calculation of the effective interest rate. All changes in lifetime expected credit losses subsequent to the assets’ initial recognition are recognised as an impairment charge. A loan or advance is normally written off, either partially or in full, against the related allowance when the proceeds from realising any available security have been received or there is no realistic prospect of recovery and the amount of the loss has been determined. Subsequent recoveries of amounts previously written off decrease the amount of impairment losses recorded in the income statement. For both secured and unsecured retail balances, the write-off takes place only once an extensive set of collections processes has been completed, or the status of the account reaches a point where policy dictates that continuing attempts to recover are no longer appropriate. For commercial lending, a write-off occurs if the loan facility with the customer is restructured, the asset is under administration and the only monies that can be received are the amounts estimated by the administrator, the underlying assets are disposed and a decision is made that no further settlement monies will be received, or external evidence (for example, third-party valuations) is available that there has been an irreversible decline in expected cash flows.
Property, plant and equipment	Property, plant and equipment (other than investment property) is included at cost less accumulated depreciation. The value of land (included in premises) is not depreciated. Depreciation on other assets is calculated using the straight-line method to allocate the difference between the cost and the residual value over their estimated useful lives, as follows: the shorter of 50 years and the remaining period of the lease for freehold/long and short leasehold premises; the shorter of 10 years and, if lease renewal is not likely, the remaining period of the lease for leasehold improvements; 10 to 20 years for fixtures and furnishings; and 2 to 8 years for other equipment and motor vehicles. The assets’ residual values and useful lives are reviewed and, if appropriate, revised at each balance sheet date. Assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. In assessing the recoverable amount of assets the Group considers the effects of potential or actual changes in legislation, customer behaviour, climate-related risks and other factors on the asset’s CGU. In the event that an asset’s CGU carrying amount is determined to be greater than its recoverable amount the asset is written down immediately. Investment property comprises freehold and long leasehold land and buildings that are held either to earn rental income or for capital accretion or both, primarily within the life insurance funds. In accordance with the guidance published by the Royal Institution of Chartered Surveyors, investment property is carried at fair value based on current prices for similar properties, adjusted for the specific characteristics of the property (such as location or condition). If this information is not available, the Group uses alternative valuation methods such as discounted cash flow projections or recent prices in less active markets. These valuations are reviewed at least annually by independent professionally qualified valuers. Investment property being redeveloped for continuing use as investment property, or for which the market has become less active, continues to be valued at fair value.
Leases	Under IFRS 16, a lessor is required to determine whether a lease is a finance or operating lease. A lessee is not required to make this determination. (1) As lessor Assets leased to customers are classified as finance leases if the lease agreements transfer substantially all of the risks and rewards of ownership to the lessee but not necessarily legal title. All other leases are classified as operating leases. When assets are subject to finance leases, the present value of the lease payments, together with any unguaranteed residual value, is recognised as a receivable, net of allowances for expected credit losses and residual value impairment, within loans and advances to banks and customers. The difference between the gross receivable and the present value of the receivable is recognised as unearned finance lease income. Finance lease income is recognised in interest income over the term of the lease using the net investment method (before tax) so as to give a constant rate of return on the net investment in the lease. Unguaranteed residual values are reviewed regularly to identify any impairment. Operating lease assets are included within other assets at cost and depreciated over their estimated useful lives. The depreciation charge is based on the asset’s residual value and the life of the lease. Operating lease rental income is recognised on a straight-line basis over the life of the lease. The Group evaluates non-lease arrangements such as outsourcing and similar contracts to determine if they contain a lease which is then accounted for separately. (2) As lessee Leases are recognised as a right-of-use asset and a corresponding liability at the date at which the leased asset is available for use by the Group. Assets and liabilities arising from a lease are initially measured on a present value basis. The lease payments are discounted using the interest rate implicit in the lease, if that rate can be determined, or the Group’s incremental borrowing rate appropriate for the right-of-use asset arising from the lease, and the liability recognised within other liabilities. Lease payments are allocated between the liability and finance cost. The finance cost is charged to profit or loss over the lease period so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. The right-of-use asset is depreciated over the shorter of the asset’s useful life and the lease term on a straight-line basis. Payments associated with short-term leases and leases of low-value assets are recognised on a straight-line basis as an expense in profit or loss. Short-term leases are leases with a lease term of twelve months or less. Low-value assets comprise IT equipment and small items of office furniture.
Employee benefits	Short-term employee benefits, such as salaries, paid absences, performance-based cash awards and social security costs, are recognised over the period in which the employees provide the related services. (1) Pension schemes The Group operates a number of post-retirement benefit schemes for its employees including both defined benefit and defined contribution pension plans. A defined benefit scheme is a pension plan that defines an amount of pension benefit that an employee will receive on retirement, dependent on one or more factors such as age, years of pensionable service and pensionable salary. A defined contribution plan is a pension plan into which the Group pays fixed contributions; there is no legal or constructive obligation to pay further contributions. (i) Defined benefit schemes Scheme assets are included at their fair value and scheme liabilities are measured on an actuarial basis using the projected unit credit method. The defined benefit scheme liabilities are discounted using rates equivalent to the market yields at the balance sheet date on high-quality corporate bonds that are denominated in the currency in which the benefits will be paid, and that have terms to maturity approximating to the terms of the related pension liability. The Group’s income statement charge includes the current service cost of providing pension benefits, past service costs, net interest expense (income), and plan administration costs that are not deducted from the return on plan assets. Past service costs, which represents the change in the present value of the defined benefit obligation resulting from a plan amendment or curtailment, are recognised when the plan amendment or curtailment occurs. Net interest expense (income) is calculated by applying the discount rate at the beginning of the period to the net defined benefit liability or asset. Remeasurements, comprising actuarial gains and losses, the return on plan assets (excluding amounts included in net interest expense (income) and net of the cost of managing the plan assets), and the effect of changes to the asset ceiling (if applicable) are reflected immediately in the balance sheet with a charge or credit recognised in other comprehensive income in the period in which they occur. Remeasurements recognised in other comprehensive income are reflected immediately in retained profits and will not subsequently be reclassified to profit or loss. The Group’s balance sheet includes the net surplus or deficit, being the difference between the fair value of scheme assets and the discounted value of scheme liabilities at the balance sheet date. Surpluses are only recognised to the extent that they are recoverable through reduced contributions in the future or through refunds from the schemes. In assessing whether a surplus is recoverable, the Group considers (i) its current right to obtain a refund or a reduction in future contributions and (ii) the rights of other parties existing at the balance sheet date. In determining the rights of third parties existing at the balance sheet date, the Group does not anticipate any future acts by other parties. (ii) Defined contribution schemes The costs of the Group’s defined contribution plans are charged to the income statement in the period in which they fall due. (2) Share-based compensation The Group operates a number of equity-settled, share-based compensation plans in respect of services received from certain of its employees. The value of the employee services received in exchange for equity instruments granted under these plans is recognised as an expense over the vesting period of the instruments, with a corresponding increase in equity. This expense is determined by reference to the fair value of the number of equity instruments that are expected to vest. The fair value of equity instruments granted is based on market prices, if available, at the date of grant. In the absence of market prices, the fair value of the instruments at the date of grant is estimated using an appropriate valuation technique, such as a Black-Scholes option pricing model or a Monte Carlo simulation. The determination of fair values excludes the impact of any non-market vesting conditions, which are included in the assumptions used to estimate the number of options that are expected to vest. At each balance sheet date, this estimate is reassessed and if necessary revised. Any revision of the original estimate is recognised in the income statement, together with a corresponding adjustment to equity. Cancellations by employees of contributions to the Group’s Save As You Earn plans are treated as non-vesting conditions and the Group recognises, in the year of cancellation, the amount of the expense that would have otherwise been recognised over the remainder of the vesting period. Modifications are assessed at the date of modification and any incremental charges are charged to the income statement.
Taxation	Tax expense comprises current and deferred tax. Current and deferred tax are charged or credited in the income statement except to the extent that the tax arises from a transaction or event which is recognised, in the same or a different period, outside the income statement (either in other comprehensive income, directly in equity, or through a business combination), in which case the tax appears in the same statement as the transaction that gave rise to it. The tax consequences of the Group’s dividend payments (including distributions on other equity instruments), if any, are charged or credited to the statement in which the profit distributed originally arose. Current tax is the amount of corporate income taxes expected to be payable or recoverable based on the profit for the period as adjusted for items that are not taxable or not deductible, and is calculated using tax rates and laws that were enacted or substantively enacted at the balance sheet date. Current tax includes amounts provided in respect of uncertain tax positions when management expects that, upon examination of the uncertainty by His Majesty’s Revenue and Customs (HMRC) or other relevant tax authority, it is more likely than not that an economic outflow will occur. Provisions reflect management’s best estimate of the ultimate liability based on their interpretation of tax law, precedent and guidance, informed by external tax advice as necessary. Changes in facts and circumstances underlying these provisions are reassessed at each balance sheet date, and the provisions are remeasured as required to reflect current information. For the Group’s long-term insurance businesses, the tax expense is analysed between tax that is payable in respect of policyholders’ returns and tax that is payable on the shareholders’ returns. This allocation is based on an assessment of the rates of tax which will be applied to the returns under the current UK tax rules. Deferred tax is recognised on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the balance sheet. Deferred tax is calculated using tax rates and laws that have been enacted or substantively enacted at the balance sheet date, and which are expected to apply when the related deferred tax asset is realised or the deferred tax liability is settled. Deferred tax liabilities are generally recognised for all taxable temporary differences but not recognised for taxable temporary differences arising on investments in subsidiaries where the reversal of the temporary difference can be controlled and it is probable that the difference will not reverse in the foreseeable future. Deferred tax liabilities are not recognised on temporary differences that arise from goodwill which is not deductible for tax purposes. Deferred tax assets are recognised to the extent it is probable that taxable profits will be available against which the deductible temporary differences can be utilised, and are reviewed at each balance sheet date and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered. Deferred tax assets and liabilities are not recognised in respect of temporary differences that arise on initial recognition of assets and liabilities acquired other than in a business combination. Deferred tax is not discounted.
Insurance	The Group undertakes both life insurance and general insurance business. Insurance and participating investment contracts are accounted for under IFRS 4 Insurance Contracts, which permits (with certain exceptions) the continuation of accounting practices for measuring insurance and participating investment contracts that applied prior to the adoption of IFRS. The Group, therefore, continues to account for these products using UK GAAP and UK established practice. Products sold by the life insurance business are classified into three categories: • Insurance contracts – these contracts transfer significant insurance risk and may also transfer financial risk. The Group defines significant insurance risk as the possibility of having to pay benefits on the occurrence of an insured event which are significantly more than the benefits payable if the insured event were not to occur. These contracts may or may not include discretionary participation features • Investment contracts containing a discretionary participation feature (participating investment contracts) – these contracts do not transfer significant insurance risk, but contain a contractual right which gives the holder the right to receive, in addition to the guaranteed benefits, further additional discretionary benefits or bonuses that are likely to be a significant proportion of the total contractual benefits and the amount and timing of which is at the discretion of the Group, within the constraints of the terms and conditions of the instrument and based upon the performance of specified assets • Non-participating investment contracts – these contracts do not transfer significant insurance risk or contain a discretionary participation feature For certain investment contracts, the contract can be partly invested in units which contain a discretionary participation feature (DPF) and partly in units without. Where switching levels for similar contracts are deemed to be significant, new investment contracts which contain an option to switch into investment contracts with DPF have been classified as participating investment contracts. Where the switching levels are not deemed to be significant, a new contract is split, with units containing a DPF being allocated as a participating investment contract and the units without a DPF as a non-participating investment contract. The general insurance business issues only insurance contracts. (1) Life insurance business (i) Accounting for insurance and participating investment contracts Premiums and claims Premiums received in respect of insurance and participating investment contracts are recognised as revenue when due except for unit-linked contracts on which premiums are recognised as revenue when received. Claims are recorded as an expense on the earlier of the maturity date or the date on which the claim is notified. Liabilities Changes in the value of liabilities are recognised in the income statement through insurance claims and changes in insurance and investment contract liabilities. • Insurance and participating investment contracts in the Group’s with-profit funds Liabilities of the Group’s with-profit funds, including guarantees and options embedded within products written by these funds, are stated at their realistic values in accordance with the Prudential Regulation Authority’s realistic capital regime, except that projected transfers out of the funds into other Group funds are recorded in the unallocated surplus (see below). Further details on valuation under the realistic capital regime are included in note 31 Liabilities arising from insurance contracts and participating investment contracts. • Insurance contracts which are not unit-linked or in the Group’s with-profit funds A liability for contractual benefits that are expected to be incurred in the future is recorded when the premiums are recognised. The liability is calculated by estimating the future cash flows over the duration of in-force policies and discounting them back to the valuation date allowing for probabilities of occurrence. The liability will vary with movements in interest rates and with the cost of life insurance and annuity benefits where future mortality is uncertain. Assumptions are made in respect of all material factors affecting future cash flows, including future interest rates, mortality and costs. Further details on valuation are included in note 31 Liabilities arising from insurance contracts and participating investment contracts. • Insurance and participating investment contracts which are unit-linked Liabilities for unit-linked insurance contracts and participating investment contracts are stated at the bid value of units plus an additional allowance where appropriate (such as for any excess of future expenses over charges). The liability is increased or reduced by the change in the unit prices and is reduced by policy administration fees, mortality and surrender charges and any withdrawals. Benefit claims in excess of the account balances incurred in the period are also charged through insurance claims and changes in insurance and investment contract liabilities. Revenue consists of fees deducted for mortality, policy administration and surrender charges. Unallocated surplus Any amounts in the with-profit funds not yet determined as being due to policyholders or shareholders are recognised as an unallocated surplus which is shown separately from liabilities arising from insurance contracts and participating investment contracts. (ii) Accounting for non-participating investment contracts The Group’s non-participating investment contracts are primarily unit-linked. These contracts are accounted for as financial liabilities whose value is contractually linked to the fair values of financial assets within the Group’s unitised investment funds. The value of the unit-linked financial liabilities is determined using current unit prices multiplied by the number of units attributed to the contract holders at the balance sheet date. Their value is never less than the amount payable on surrender, discounted for the required notice period where applicable. Investment returns (including movements in fair value and investment income) allocated to those contracts are recognised in the income statement through insurance claims and changes in insurance and investment contract liabilities. Deposits and withdrawals are not accounted for through the income statement but are accounted for directly in the balance sheet as adjustments to the non-participating investment contract liability. The Group receives investment management fees in the form of an initial adjustment or charge to the amount invested. These fees are in respect of services rendered in conjunction with the issue and management of investment contracts where the Group actively manages the consideration received from its customers to fund a return that is based on the investment profile that the customer selected on origination of the contract. These services comprise an indeterminate number of acts over the lives of the individual contracts and, therefore, the Group defers these fees and recognises them over the estimated lives of the contracts, in line with the provision of investment management services. Costs which are directly attributable and incremental to securing new non-participating investment contracts are deferred. This asset is subsequently amortised over the period of the provision of investment management services and its recoverability is reviewed in circumstances where its carrying amount may not be recoverable. If the asset is greater than its recoverable amount it is written down immediately through fee and commission expense in the income statement. All other costs are recognised as expenses when incurred. (iii) Value of in-force business The Group recognises as an asset the value of in-force business in respect of insurance contracts and participating investment contracts. The asset represents the present value of the shareholders’ interest in the profits expected to emerge from those contracts written at the balance sheet date. This is determined after making appropriate assumptions about future economic and operating conditions such as future mortality and persistency rates and includes allowances for both non-market risk and for the realistic value of financial options and guarantees. Each cash flow is valued using the discount rate consistent with that applied to such a cash flow in the capital markets. The asset in the consolidated balance sheet is presented gross of attributable tax and movements in the asset are reflected within other operating income in the income statement. The Group’s contractual rights to benefits from providing investment management services in relation to non-participating investment contracts acquired in business combinations and portfolio transfers are measured at fair value at the date of acquisition. The resulting asset is amortised over the estimated lives of the contracts. At each reporting date an assessment is made to determine if there is any indication of impairment. Where impairment exists, the carrying value of the asset is reduced to its recoverable amount and the impairment loss recognised in the income statement. (2) General insurance business The Group both underwrites and acts as intermediary in the sale of general insurance products. Underwriting premiums are included in insurance premium income, net of refunds, in the period in which insurance cover is provided to the customer; premiums received relating to future periods are deferred in the balance sheet within liabilities arising from insurance contracts and participating investment contracts on a basis that reflects the length of time for which contracts have been in-force and the projected incidence of risk over the term of the contract and only credited to the income statement when earned. Broking commission is recognised when the underwriter accepts the risk of providing insurance cover to the customer. Where appropriate, provision is made for the effect of future policy terminations based upon past experience. The underwriting business makes provision for the estimated cost of claims notified but not settled and claims incurred but not reported at the balance sheet date. The provision for the cost of claims notified but not settled is based upon a best estimate of the cost of settling the outstanding claims after taking into account all known facts. In those cases where there is insufficient information to determine the required provision, statistical techniques are used which take into account the cost of claims that have recently been settled and make assumptions about the future development of the outstanding cases. Similar statistical techniques are used to determine the provision for claims incurred but not reported at the balance sheet date. Claims liabilities are not discounted. (3) Liability adequacy test At each balance sheet date liability adequacy tests are performed to ensure the adequacy of insurance and participating investment contract liabilities net of related deferred cost assets and value of in-force business. In performing these tests, current best estimates of discounted future contractual cash flows and claims handling and policy administration expenses, as well as investment income from the assets backing such liabilities, are used. Any deficiency is immediately charged to the income statement, initially by writing off the relevant assets and subsequently by establishing a provision for losses arising from liability adequacy tests. (4) Reinsurance The presentation of contracts entered into by the Group with reinsurers under which the Group is compensated for amounts payable on one or more other contracts issued by the Group is dependent on whether the contract with the reinsurer transfers significant insurance risk to the reinsurer. Where the reinsurance contract transfers significant insurance risk, it is classified as an insurance contract and the asset is recognised separately on the balance sheet. Where the reinsurance contract does not transfer significant insurance risk to the reinsurer, the assets arising from contracts held with reinsurers are presented within financial assets at fair value through profit or loss. (i) Contracts with reinsurers that transfer significant insurance risk Amounts recoverable from or due to reinsurers are measured consistently with the amounts associated with the reinsured contracts and in accordance with the terms of each reinsurance contract and are regularly reviewed for impairment. Premiums payable for reinsurance contracts are recognised as an expense when due within insurance premium income. Changes in the reinsurance recoverable assets are recognised in the income statement through insurance claims and changes in insurance and investment contract liabilities. (ii) Contracts with reinsurers that do not transfer significant insurance risk Contracts that do not transfer significant insurance risk to the reinsurer are recognised within financial assets at fair value through profit or loss as they are within a portfolio of financial assets that is managed, and whose performance is evaluated, on a fair value basis. These contracts, while legally reinsurance contracts, do not meet the definition of a reinsurance contract under IFRS. Investment returns (including movements in fair value and investment income) allocated to these contracts are recognised in insurance claims and changes in insurance and investment contract liabilities.
Foreign currency translation	Items included in the financial statements of each of the Group’s entities are measured using the currency of the primary economic environment in which the entity operates (the functional currency). Foreign currency transactions are translated into the appropriate functional currency using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at year end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in the income statement, except when recognised in other comprehensive income as qualifying cash flow or net investment hedges. Non-monetary assets that are measured at fair value are translated using the exchange rate at the date that the fair value was determined. Translation differences on equities and similar non-monetary items held at fair value through profit and loss are recognised in profit or loss as part of the fair value gain or loss. Translation differences on non-monetary financial assets measured at fair value through other comprehensive income, such as equity shares, are included in the fair value reserve in equity unless the asset is a hedged item in a fair value hedge. The results and financial position of all Group entities that have a functional currency different from the presentation currency are translated into the presentation currency as follows: the assets and liabilities of foreign operations, including goodwill and fair value adjustments arising on the acquisition of a foreign entity, are translated into sterling at foreign exchange rates ruling at the balance sheet date; and the income and expenses of foreign operations are translated into sterling at average exchange rates unless these do not approximate to the foreign exchange rates ruling at the dates of the transactions, in which case income and expenses are translated at the dates of the transactions. Foreign exchange differences arising on the translation of a foreign operation are recognised in other comprehensive income and accumulated in a separate component of equity together with exchange differences arising from the translation of borrowings and other currency instruments designated as hedges of such investments (see (F)(3) above). On disposal or liquidation of a foreign operation, the cumulative amount of exchange differences relating to that foreign operation is reclassified from equity and included in determining the profit or loss arising on disposal or liquidation.
Provisions and contingent liabilities	Provisions are recognised in respect of present obligations arising from past events where it is probable that outflows of resources will be required to settle the obligations and they can be reliably estimated. Contingent liabilities are possible obligations whose existence depends on the outcome of uncertain future events or those present obligations where the outflows of resources are uncertain or cannot be measured reliably. Contingent liabilities are not recognised in the financial statements but are disclosed unless they are remote. Provision is made for expected credit losses in respect of irrevocable undrawn loan commitments and financial guarantee contracts (see (H) above).
Share capital	Incremental costs directly attributable to the issue of new shares or options or to the acquisition of a business are shown in equity as a deduction, net of tax, from the proceeds. Dividends paid on the Group’s ordinary shares are recognised as a reduction in equity in the period in which they are paid. Where the Company or any member of the Group purchases the Company’s share capital, the consideration paid is deducted from shareholders’ equity as treasury shares until they are cancelled; if these shares are subsequently sold or reissued, any consideration received is included in shareholders’ equity.
Cash and cash equivalents	For the purposes of the cash flow statement, cash and cash equivalents comprise cash and non-mandatory deposits held with central banks, mandatory deposits held with central banks in demand accounts and amounts due from banks with an original maturity of less than three months that are available to finance the Group’s day-to-day operations.
Segment analysis	Lloyds Banking Group provides a wide range of banking and financial services in the UK and in certain locations overseas. The Group Executive Committee (GEC) has been determined to be the chief operating decision-maker, as defined by IFRS 8 Operating Segments , for the Group. The Group’s operating segments reflect its organisational and management structures. The GEC reviews the Group’s internal reporting based around these segments in order to assess performance and allocate resources. They consider interest income and expense on a net basis and consequently the total interest income and expense for all reportable segments is presented net. The segments are differentiated by the type of products provided and by whether the customers are individuals or corporate entities. The segmental results and comparatives are presented on an underlying basis (pre-tax), the basis reviewed by the chief operating decision-maker. The underlying basis is derived from the recognition and measurement principles of IFRS with the effects of the following excluded in arriving at underlying profit before tax: • Restructuring costs relating to merger, acquisition and integration activities • Volatility and other items, which includes the effects of certain asset sales, the volatility relating to the Group’s hedging arrangements and that arising in the insurance businesses, the unwind of acquisition-related fair value adjustments and the amortisation of purchased intangible assets • Payment protection insurance remediation provisions, excluding litigation costs For the purposes of the underlying income statement, operating lease depreciation (net of gains on disposal of operating lease assets) is shown as an adjustment to total underlying income. During the year ended 31 December 2022, there were changes as a result of the Group restructure effective from 1 July 2022 and other methodology changes (comparatives have been restated accordingly): • Business Banking and Commercial Cards moved from Retail to Commercial Banking. Wealth moved from Insurance and Wealth to Retail. • Insurance and Wealth was renamed Insurance, Pensions and Investments. • The Group reviewed and updated its methodology for liquidity transfer pricing between segments. • The Group revised the treatment of restructuring costs and all such costs other than those relating to merger, acquisition and integration activities are now reported within operating costs in arriving at underlying profit. • Non lending-related fraud costs, previously included within underlying impairment, are now reported as part of operating costs (this has not impacted the statutory impairment charge). The Group's restructure created a revised organisational structure under its divisions. The Group completed a review and determined that it had three operating and reportable segments: Retail; Commercial Banking; and Insurance, Pensions and Investments: • Retail offers a broad range of financial services products to personal customers, including current accounts, savings, mortgages, credit cards, unsecured loans, motor finance and leasing solutions. • Commercial Banking serves small and medium businesses as well as corporate and institutional clients, providing lending, transactional banking, working capital management, debt financing and risk management services. • Insurance, Pensions and Investments offers insurance, investment and pension management products and services. Other comprises income and expenditure not attributed to the Group’s operating segments. These amounts include those arising from the Group’s equities business, residual net interest income after transfer pricing (including the central recovery of the Group’s distributions on other equity instruments) and certain gains from gilt sales. Inter-segment services are generally recharged at cost, although some attract a margin. In particular, a profit margin is charged on the internal commission arrangements between the branch network and other distribution channels and the insurance product manufacturing businesses within the Group. Inter-segment lending and deposits are generally entered into at market rates, except that non-interest bearing balances are priced at a rate that reflects the external yield that could be earned on such funds. For the majority of those derivative contracts entered into by business units for risk management purposes, the business unit recognises the net interest income or expense on an accrual accounting basis and transfers the remainder of the movement in the fair value of the derivative to the central function where the resulting accounting volatility is managed where possible through the establishment of hedge accounting relationships. Any change in fair value of the hedged instrument attributable to the hedged risk is also recorded within the central function. This allocation of the fair value of the derivative and change in fair value of the hedged instrument attributable to the hedged risk avoids accounting asymmetry in segmental results and leads to accounting volatility, which is managed centrally and reported within Other.

Disclosure of Detailed Information about ECL Sensitivity to Economic Assumptions	The table below shows the Group’s ECL for the probability-weighted, upside, base case, downside and severe downside scenarios, with the severe downside scenario incorporating adjustments made to CPI inflation and UK Bank Rate paths. The stage allocation for an asset is based on the overall scenario probability-weighted PD and hence the staging of assets is constant across all the scenarios. In each economic scenario the ECL for individual assessments and post-model adjustments is typically held constant reflecting the basis on which they are evaluated. For 31 December 2022, however, post-model adjustments in Commercial Banking have been apportioned across the scenarios to better reflect the sensitivity of these adjustments to each scenario. Judgements applied through changes to model inputs are reflected in the scenario ECL sensitivities. The probability-weighted view shows the extent to which a higher ECL allowance has been recognised to take account of multiple economic scenarios relative to the base case; the uplift being £692 million compared to £223 million at 31 December 2021.

The table below shows the Group’s ECL for the upside, base case, downside and severe downside scenarios, with staging of assets based on each specific scenario probability of default. ECL applied through individual assessments and the majority of post-model adjustments are reported flat against each economic scenario, reflecting the basis on which they are evaluated. A probability-weighted scenario is not shown as this does not reflect the basis on which ECL is reported. Comparing the probability-weighted ECL in the table above to the base case ECL with base case scenario specific staging, as shown in the table below, results in an uplift of £820 million compared to £230 million at 31 December 2021.

Schedule of Accounting Estimates and Judgements	NOTE 3: CRITICAL ACCOUNTING JUDGEMENTS AND KEY SOURCES OF ESTIMATION UNCERTAINTY The preparation of the Group’s financial statements in accordance with IFRS requires management to make judgements, estimates and assumptions in applying the accounting policies that affect the reported amounts of assets, liabilities, income and expenses. Due to the inherent uncertainty in making estimates, actual results reported in future periods may be based upon amounts which differ from those estimates. Estimates, judgements and assumptions are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. In preparing the financial statements, the Group has considered the impact of climate-related risks on its financial position and performance. While the effects of climate change represent a source of uncertainty, the Group does not consider there to be a material impact on its judgements and estimates from the physical, transition and other climate-related risks in the short term. The significant judgements, apart from those involving estimation, made by management in applying the Group’s accounting policies in these financial statements (critical judgements) and the key sources of estimation uncertainty that may have a significant risk of causing a material adjustment to the carrying amount of assets and liabilities within the next financial year (key sources of estimation uncertainty), which together are considered critical to the Group’s results and financial position, are as follows: Allowance for expected credit losses Critical judgements: Determining an appropriate definition of default against which a probability of default, exposure at default and loss given default parameter can be evaluated Establishing the criteria for a significant increase in credit risk (SICR) The use of management judgement alongside impairment modelling processes to adjust inputs, parameters and outputs to reflect risks not captured by models Key source of estimation uncertainty: Base case and multiple economic scenarios (MES) assumptions, including the rate of unemployment and the rate of change of house prices, required for creation of MES scenarios and forward-looking credit parameters The Group recognises an allowance for expected credit losses (ECLs) for loans and advances to customers and banks, other financial assets held at amortised cost, financial assets (other than equity investments) measured at fair value through other comprehensive income and certain loan commitment and financial guarantee contracts. At 31 December 2022, the Group’s expected credit loss allowance was £4,903 million (2021: £4,042 million), of which £4,580 million (2021: £3,842 million) was in respect of drawn balances . The calculation of the Group’s expected credit loss allowances and provisions against loan commitments and guarantees under IFRS 9 requires the Group to make a number of judgements, assumptions and estimates. Further information on the critical accounting judgements and key sources of estimation uncertainty (see above) and other significant judgements and estimates is set out in note 19. Valuation of assets and liabilities arising from insurance business Critical judgement: Future economic and operating conditions Key sources of estimation uncertainty: Future investment returns Future mortality rates Future expenses These judgements and estimates are subject to significant uncertainty. At 31 December 2022, the Group recognised a value of in-force business asset of £5,244 million (2021: £5,317 million) and an acquired value of in-force business asset of £175 million (2021: £197 million). The value of in-force business asset represents the estimated present value of future profits expected to arise from the portfolio of in-force life insurance and participating investment contracts. The valuation of this asset requires judgements to be made about future economic and operating conditions which are inherently uncertain and changes could significantly affect the value attributed to this asset. These judgements are used to determine appropriate assumptions for the asset’s valuation including the appropriate risk-free rate, retail price inflation and expense inflation. The methodology used to value this asset and the key assumptions that have been made in determining the carrying value of the value of in-force business asset at 31 December 2022 are set out in note 24. At 31 December 2022, the Group carried total liabilities arising from insurance contracts and participating investment contracts of £106,893 million (2021: £123,423 million). Elements of the valuations of liabilities arising from insurance contracts and participating investment contracts require management to estimate future investment returns, future mortality rates and future expenses. These estimates are subject to significant uncertainty. The methodology used to value these liabilities and the key assumptions that have been made in determining their carrying value are set out in note 31. The effect of changes to critical estimates used by management to determine the life insurance assets and liabilities is set out in note 32, which presents the impact of changes to the estimates made on the Group’s profit before tax and shareholders’ equity as management believes that this analysis best presents these sensitivities in a manner that helps the user of the financial statements to understand the judgements made by management and the level of estimation uncertainty. Defined benefit pension scheme obligations Critical judgement: Determination of an appropriate yield curve Key sources of estimation uncertainty: Discount rate applied to future cash flows Expected lifetime of the schemes’ members Expected rate of future inflationary increases The net asset recognised in the balance sheet at 31 December 2022 in respect of the Group’s defined benefit pension scheme obligations was £3,732 million comprising an asset of £3,823 million and a liability of £91 million (2021: a net asset of £4,404 million comprising an asset of £4,531 million and a liability of £127 million). The Group’s accounting policy for its defined benefit pension scheme obligations is set out in note 2(K). The accounting valuation of the Group’s defined benefit pension schemes’ liabilities requires management to make a number of assumptions. The key sources of estimation uncertainty are the discount rate applied to future cash flows, the expected lifetime of the schemes’ members and the expected rate of future inflationary increases. Income statement and balance sheet sensitivities to changes in the critical accounting estimates and other actuarial assumptions are provided in part (v) of note 35. Uncertain tax positions Critical judgement: Interpreting tax rules on the Group’s open tax matters The Group has an open matter in relation to a claim for group relief of losses incurred in its former Irish banking subsidiary, which ceased trading on 31 December 2010. In 2013, HMRC informed the Group that its interpretation of the UK rules means that the group relief is not available. In 2020, HMRC concluded their enquiry into the matter and issued a closure notice. The Group’s interpretation of the UK rules has not changed and hence it has appealed to the First Tier Tax Tribunal, with a hearing expected in 2023. If the final determination of the matter by the judicial process is that HMRC’s position is correct, management estimate that this would result in an increase in current tax liabilities of approximately £875 million (including interest) and a reduction in the Group’s deferred tax asset of approximately £295 million. The Group, having taken appropriate advice, does not consider that this is a case where additional tax will ultimately fall due. The Group makes other estimates in relation to tax which do not require significant judgements, see further discussion in note 36. Regulatory and legal provisions Critical judgements: Determining the scope of reviews required by regulators The impact of legal decisions that may be relevant to claims received Determining whether a reliable estimate is available for obligations arising from past events Key sources of estimation uncertainty: The number of future complaints The proportion of complaints that will be upheld The average cost of redress At 31 December 2022, the Group carried provisions of £803 million (2021: £1,156 million) against the cost of making redress payments to customers and the related administration costs in connection with historical regulatory breaches. Determining the amount of the provisions, which represent management’s best estimate of the cost of settling these issues, requires the exercise of significant judgement and estimation. It will often be necessary to form a view on matters which are inherently uncertain, such as the scope of reviews required by regulators, and to estimate the number of future complaints, the extent to which they will be upheld, the average cost of redress and the impact of decisions reached by legal and other review processes that may be relevant to claims received. Consequently the continued appropriateness of the underlying assumptions is reviewed on a regular basis against actual experience and other relevant evidence and adjustments made to the provisions where appropriate. Management has applied significant judgement in determining the provision required for HBOS Reading; further details are provided in note 37. Fair value of financial instruments Key source of estimation uncertainty: Interest rate spreads, earnings multiples and interest rate volatility At 31 December 2022, the carrying value of the Group’s financial instrument assets held at fair value was £228,516 million (2021: £256,959 million), and its financial instrument liabilities held at fair value was £84,772 million (2021: £86,223 million). The Group’s valuation control framework and a description of level 1, 2 and 3 financial assets and liabilities is set out in note 49(2). The valuation techniques for level 3 financial instruments involve management judgement and estimates, the extent of which depends on the complexity of the instrument and the availability of market observable information. In addition, in line with market practice, the Group applies credit, debit and funding valuation adjustments in determining the fair value of its uncollateralised derivative positions. A description of these adjustments is set out in note 49. A quantitative analysis of the sensitivities to market risk arising from the Group’s trading portfolios is set out in the tables marked audited on page 95 Capitalised software enhancements Critical judgement: Assessing future trading conditions that could affect the Group’s business operations Key source of estimation uncertainty: Estimated useful life of internally generated capitalised software At 31 December 2022, the carrying value of the Group’s capitalised software enhancements was £4,060 million (2021: £3,435 million). In determining the estimated useful life of capitalised software enhancements, management consider the product’s lifecycle and the Group’s technology strategy; assets are reviewed annually to assess whether there is any indication of impairment and to confirm that the remaining estimated useful life is still appropriate. For the year ended 31 December 2022, the amortisation charge was £833 million (2021: £892 million), and at 31 December 2022, the weighted-average remaining estimated useful life of the Group’s capitalised software enhancements was 4.5 years (2021: 4.7 years). If the Group reduced by one year the estimated useful life of those assets with a remaining estimated useful life of more than two years at 31 December 2022, the 2023 amortisation charge would be approximately £200 million higher. Consideration of climate change Financial statement preparation includes the consideration of the impact of climate change on the Group’s financial statements. There has been no material impact identified on the financial reporting judgement and estimates. In particular, the directors considered the impact of climate change in respect of the: • Going concern of the Group for a period of at least 12 months from the date of approval of the financial statements • Assessment of impairment of non-financial assets including goodwill • Carrying value and useful economic lives of property, plant and equipment • Fair value of financial assets and liabilities. These are generally based on market indicators which include the market’s assessment of climate risk • Economic scenarios used for measurement of expected credit losses and the behavioural lifetime of assets against the expected time horizons of when climate risks may materialise • Forecasting of the Group's future UK taxable profits, which impacts deferred tax recognition Whilst there is currently no material short-term impact of climate change expected, the Group acknowledges the long-term nature of climate risk and continues to monitor and assess climate risks highlighted in the risk management section on page 63 The following table demonstrates the effect of reasonably possible changes in key assumptions on profit before tax and equity disclosed in these financial statements assuming that the other assumptions remain unchanged. In practice this is unlikely to occur, and changes in some assumptions may be correlated. These amounts include movements in assets, liabilities and the value of the in-force business in respect of insurance contracts and participating investment contracts. The impact is shown in one direction but can be assumed to be reasonably symmetrical. 2022 2021 Change in variable Increase Increase Increase Increase Critical accounting estimates Annuitant mortality 1 5% reduction (188) (152) (301) (244) Future maintenance and investment expenses 2 10% reduction 309 250 355 288 Widening of credit default spreads 3 0.25% addition (284) (230) (433) (351) Increase in illiquidity premia 4 0.10% addition 114 92 190 154 Other accounting estimates Non-annuitant mortality and morbidity 5 5% reduction 22 18 13 11 Lapse rates 6 10% reduction 122 99 88 71 Risk-free rate 7 0.25% reduction 44 35 44 35 Guaranteed annuity option take up 8 5% addition (2) (2) (2) (2) Equity investment volatility 9 1% addition (2) (1) (2) (1) 1 This sensitivity shows the impact on the annuity and deferred annuity business of reducing mortality rates to 95 per cent of the expected rate. 2 This sensitivity shows the impact of reducing maintenance expenses and investment expenses to 90 per cent of the expected rate. 3 This sensitivity shows the impact of a 25 basis point increase in credit default spreads on corporate bonds and the corresponding reduction in market values. Swap curves, the risk-free rate and illiquidity premia are all assumed to be unchanged. 4 This sensitivity shows the impact of a 10 basis point increase in the allowance for illiquidity premia. It assumes the overall spreads on assets are unchanged and hence market values are unchanged. Swap curves and the non-annuity risk-free rate are both assumed to be unchanged. The increased illiquidity premium increases the annuity risk-free rate. 5 This sensitivity shows the impact of reducing mortality and morbidity rates on non-annuity business to 95 per cent of the expected rate. 6 This sensitivity shows the impact of reducing lapse and surrender rates to 90 per cent of the expected rate. 7 This sensitivity shows the impact on the value of in-force business, financial options and guarantee costs, statutory reserves and asset values of reducing the risk-free rate by 25 basis points. 8 This sensitivity shows the impact of a flat 5 per cent addition to the expected rate. 9 This sensitivity shows the impact of a flat 1 per cent addition to the expected rate.
