GROUP PERFORMANCE SEGMENT REPORTING 3 GROUP PERFORMANCE Performance overview The Group's net profit for Second Half 2024 was $3,648 million, up 9% on the prior period. Excluding Notable Items, net profit increased 3% to $3,607 million. Pre-provision profit was $5,449 million, an increase of 5% on the prior period. Excluding Notable Items, pre-provision profit was little changed at $5,398 million driven by a 1% increase in operating income and a 3% increase in operating expenses. • Net interest income increased 5% to $9,626 million. Excluding Notable Items, net interest income increased 2% to $9,565 million reflecting disciplined management of net interest margins and balance sheet growth. This reflected a slight expansion of core net interest margin (NIM) and a 1% increase in average interest-earning assets. Growth in average interest-earning assets was driven by increases in owner occupied mortgages, and loans to business and institutional customers. Customer deposits increased 3% reflecting the improved strength of our customer franchise across all segments. • NIM was 1.97% and comprised: – Core NIM of 1.83% which expanded by 3 basis points with higher earnings on capital and hedged deposits partly offset by narrowing of deposit spreads as customers preferred higher yield savings and term deposits and tighter loan spreads due to lending competition, particularly in mortgages; – Treasury and Markets income of 13 basis points, down 1 basis point; and – Notable Items, related to accounting for hedges, added 6 basis points compared to detracting 5 basis points in the prior period. • Non-interest income of $1,372 million was 6% lower. Excluding Notable Items, non-interest income of $1,382 million was also down 6% mainly due to lower Markets income. • Operating expenses of $5,549 million increased 3% due to higher costs of third party technology vendors, higher wage and salary costs along with costs related to the UNITE program. Cost Reset actions provided a partial offset. Impairment charges were $175 million or 4 basis points of average loans, compared to 9 basis points of average loans in the prior half. The charge reflects lower Collectively Assessed Provisions (CAP), mainly from the reduction in overlays as the expected losses did not materialise or are now reflected in modelled outcomes. The effective tax rate of 30.8% was broadly in line with the Australian corporate tax rate of 30%.

Treasury net interest income excludes capital benefit. b. Comparatives have been revised to conform with current period presentation. c. Net of average mortgage offset balances. Net interest income increased 5% to $9,626 million. Key drivers included: • Higher core net interest income, up 3% to $8,940 million, due to both higher net interest margin and balance sheet growth; • Treasury and Markets income, down 8% to $625 million, due to stronger Treasury performance in the prior period from interest rate positioning; and • Notable Items contributed $61 million compared to reduction of $224 million in the prior period. Average interest-earning assets increased by 1% to $975.4 billion. Growth in average loans of 2% reflects 3% growth in business loans and 2% growth in housing loans. This more than offset the reduction in personal loans which included the runoff in the auto finance portfolio. Average liquid assets decreased by 2% while other interest-earning assets increased by 2% due to increased holdings of trading securities, mainly relating to holdings of reverse repurchase agreements to facilitate WIB client transactions.

8 WESTPAC GROUP 2024 SECOND HALF FINANCIAL PERFORMANCE REVIEW GROUP PERFORMANCE Review of earnings (Continued) Net interest margin The NIM increased by 8 basis points to 1.97%. NIM comprised: • Core NIM of 1.83%, up 3 basis points with key drivers described below; • Treasury and Markets contribution of 13 basis points, down 1 basis point primarily due to stronger Treasury performance in the prior period; and • Notable Items from unrealised fair value gains for accounting purposes related to economic hedges of term funding contributed 1 basis point, compared to negative 5 basis points in the prior period. The 3 basis points increase in Core NIM was driven by: • Capital and other: 2 basis points increase primarily from higher earnings on capital balances as a result of higher interest rates, and 1 basis point increase from a remediation provision release; • Liquid assets: 2 basis points increase from a reduction in liquid asset balances due to lower cash balances; • Loan interest spread: 1 basis point decrease from tighter spreads on mortgage lending in Australia due to competition for new and existing customers and narrower spreads on business lending. Benefits from fixed to variable mortgage switching in Australia and higher spreads on mortgage lending in New Zealand provided some offsetting benefits; • Wholesale funding: 1 basis point decrease as spreads on new term wholesale funding were higher than the spreads on maturing facilities, which included the Term Funding Facility; and • Deposit interest spread: minimal impact with a mix shift towards lower spread savings accounts offset by higher earnings on hedged deposits.

Fixed rate mortgage expiration of $28 billion in the Second Half, combined with customers continuing to prefer variable rates, resulted in fixed rate mortgages declining from 15% to 10% of the portfolio; • RAMS housing loans were down 10% to $29.8 billion as the portfolio is closed to new lending; • Contraction in Australian personal lending of 3% to $9.4 billion due to higher pay down and subdued new lending; • Growth in Australian business lending of 7% to $194.1 billion. Strong loan growth in WIB, primarily from deepening relationships with existing customers in the institutional property, industrial and infrastructure sectors. Additionally, Business segment loan growth was diversified with our target sectors of health, professional services and agriculture performing well; • Auto finance loans were down $1.0 billion to $2.1 billion due to loan runoff. The sale of this portfolio was announced in October 2024; • Growth in New Zealand lending of 1% to $102.5 billion in NZ$ terms with growth in owner occupied mortgages and business lending; and • Growth in other overseas loan balances of 26% to $7.7 billion.

Key movements included: • Lower Institutional fees of $11 million from decreased underwriting income which was partly offset by higher unused credit facility fees; • Lower Australian merchants income of $10 million; and • Higher New Zealand Institutional fees of $9 million mainly due to unused credit facility fees. Net wealth management income Net wealth management income increased by 2% to $223 million with higher funds under administration from equity market valuations and improved duration-managed cash margins. Trading income Trading income decreased by 6% to $341 million. Excluding Notable Items, Trading income decreased by 4% to $351 million. Losses on FX revaluations were partly offset by favourable impacts from hedges on commodity and foreign currency derivatives. Other income Other income was a $22 million loss in the Second Half 2024 compared to a gain of $40 million in the prior period. This is primarily attributable to losses on commodity and foreign currency derivatives.

The increase reflects higher costs of third party technology vendors and wages and salaries along with costs related to the UNITE program. Staff expenses increased by 1% to $2,968 million mainly driven by wage growth, the superannuation rate increase and seasonality of employee expenses. Average FTE was flat with project demand offsetting Cost Reset initiatives. Occupancy expenses decreased by 1% to $348 million due to the Group's reduced corporate and branch footprint, including the closure of 11 branches and establishment of 12 co-locations. Technology expenses increased by 9% to $1,441 million due to higher software application maintenance and license costs, higher third-party vendor costs and the UNITE program.

The lower impairment charge was driven by a 52% reduction in the CAP charge and an increase in write-backs and recoveries. The CAP charge of $128 million comprised write-offs of $275 million which were partly offset by a benefit from other changes in CAP of $147 million. The other changes in CAP were driven by: • A reduction in portfolio overlays of $81 million due to partial release of mortgage overlays; • Lower balances in the credit card and auto finance portfolios; • An increase in mortgage delinquencies from 1.00% to 1.05%; and • A less favourable outlook for commercial property prices and GDP along with a delay in the expected timing of interest rate declines. The IAP charge of $47 million comprised: • New IAPs of $210 million, mostly in the manufacturing sector and mortgage portfolio; • Recoveries of $100 million, mostly in the credit card and personal loan portfolios; and • Write-backs of $63 million, mostly in the Business & Wealth segment.

GROUP PERFORMANCE SEGMENT REPORTING 15 SEGMENT REPORTING For reporting purposes, Westpac identifies the impact of Notable Items on income and expenses and includes a subtotal titled “Pre-provision profit”. Pre-provision profit represents profit before impairment charges and income tax expenses. Segments' operating income and operating expenses were restated in First Half 2024 following the establishment of separate Consumer and Business & Wealth operating segments. In Second Half 2024 additional restatements have been made for: • Reclassification of some deposit products from interest bearing to non interest bearing. This included some mortgage offset accounts which had a minor impact on average interest earning assets and the Net Interest Margin; and • Reallocation of Enterprise functions operating expenses to the Consumer, Business & Wealth and WIB segments. These changes have been reflected in segment reporting so that the information presented aligns with information reported internally to key decision makers. Comparatives have been restated to align with the current period presentation. $m Consumer Business & Wealth Westpac Institutional Bank Westpac New Zealand (A$)a Group Businesses Group Half Year Sept 2024 Net interest income 3,861 2,722 1,150 1,217 615 9,565 Non-interest income 273 389 599 135 (14) 1,382 Notable Items - - - (2) 53 51 Net operating income 4,134 3,111 1,749 1,350 654 10,998 Operating expenses (2,422) (1,370) (756) (616) (385) (5,549) Total operating expenses (2,422) (1,370) (756) (616) (385) (5,549) Pre-provision profit 1,712 1,741 993 734 269 5,449 Impairment (charges)/benefits (104) (47) (19) (3) (2) (175) Profit before income tax (expense)/benefit 1,608 1,694 974 731 267 5,274 Income tax (expense)/benefit and NCIb (482) (513) (288) (203) (140) (1,626) Net profit/(loss) 1,126 1,181 686 528 127 3,648 Net profit includes impact of: Notable Items (post tax)b - - - (2) 43 41 Half Year March 2024 Net interest income 3,771 2,616 1,090 1,171 703 9,351 Non-interest income 255 409 666 122 13 1,465 Notable Items - - - (6) (220) (226) Net operating income 4,026 3,025 1,756 1,287 496 10,590 Operating expenses (2,365) (1,256) (709) (646) (419) (5,395) Total operating expenses (2,365) (1,256) (709) (646) (419) (5,395) Pre-provision profit 1,661 1,769 1,047 641 77 5,195 Impairment (charges)/benefits (144) (95) (101) (22) - (362) Profit before income tax (expense)/benefit 1,517 1,674 946 619 77 4,833 Income tax (expense)/benefit and NCIb (459) (499) (265) (174) (94) (1,491) Net profit/(loss) 1,058 1,175 681 445 (17) 3,342 Net profit includes impact of: Notable Items (post tax)b - - - (4) (160) (164) a.

GROUP PERFORMANCE SEGMENT REPORTING 17 Consumer (Continued) Net profit increased 6% to $1,126 million. Pre-provision profit rose 3% to $1,712 million. Operating income increased 3% as the balance sheet grew and margins stabilised while operating expenses rose 2% reflecting the seasonality of employee costs, higher wages, salary and supplier costs and higher investment spend which was partly offset by productivity initiatives. Net interest income up 2% • The net interest margin increased one basis point to 1.70%. Drivers included: – Competition to both retain and attract new mortgage customers was offset by the benefit of switching from low spread fixed rate mortgages to higher spread variable rate mortgages; – A mix shift towards higher interest rate, lower margin savings accounts which was more than offset by higher returns on hedged deposits and a higher deposit to loan ratio; and – Higher returns on hedged capital balances offset by higher funding costs. • Net loans rose by 2% to $510.3 billion. Total mortgage growth was below system, reflecting the decision to close the RAMS business. Excluding this impact, mortgages grew 3%, mostly in variable rate mortgages, representing 1.0x APRA housing system growth. The retention of most of the $28 billion of fixed rate loans switching to variable rates, coupled with almost all new flows on variable rates, saw variable rate mortgages increase from 85% to 91% of the portfolio; • Deposits increased by 4% to $334.5 billion, representing 1.1x APRA household deposits system growth. Growth was largely in saving accounts, which increased by $11.0 billion, as customer preference continued to shift towards higher yielding products. Mortgage offset balances rose by 6% to $63.3 billion, as more customers shifted from fixed rate to variable rate mortgages with an offset feature; • With deposit growth continuing to exceed loan growth, the deposit to loan ratio improved 159 basis points to 65.5%. Non-interest income up 7% • Non-interest income increased 7% to $273 million due to higher currency conversion and credit card fees. Expenses up 2% • Operating expenses increased 2%. The main drivers included: – The seasonality of employee costs; – Inflationary pressures on wages and salaries as well as additional resources to maintain service level requirements; – Higher technology costs due to additional demand and new capabilities; and – Benefits of a simpler operating model and a smaller property footprint which included opening an additional 12 co-located branches in the period. Impairment charge of $104 million • The impairment charge was 4 basis points of average loans, compared to 6 basis points in the prior period. The charge reflects higher mortgage and other consumer loans delinquencies, which was partly offset by reductions in the mortgage overlay; and • Stressed exposure to TCE deteriorated by 6 basis points to 1.10%. Mortgage 90+ day delinquencies increased 6 basis points to 1.12%, while other consumer loan 90+ day delinquencies increased 6 basis points to 1.23%. Both increases reflect the higher cost of living, although the rate of increase in arrears slowed throughout the half.

GROUP PERFORMANCE SEGMENT REPORTING 19 Business & Wealth (Continued) Net profit increased 1% to $1,181 million. Pre-provision profit declined 2% to $1,741 million with a 3% increase in operating income more than offset by a 9% rise in operating expenses. Operating expenses were higher reflecting higher salaries and wages and seasonality of employee costs, increased investment spend and an increase in litigation provisions while operating income benefited from strong lending growth and a higher net interest margin. Net interest income up 4% • The net interest margin rose 3 basis points reflecting provision releases and higher returns on hedged deposits and capital as previous interest rate rises continue to support the replicating portfolio. This was partially offset by higher wholesale funding costs, a mix shift from at call deposits to higher interest rate, lower margin term deposits and the continued runoff of the higher spread auto finance portfolio. Excluding the impact of auto finance, lending spreads were slightly down as margins were well managed, despite the competitive environment; • Net loans increased by 5% to $102.0 billion. Business lending growth of 6% was diversified with consistent growth across most industries and products. Our target industries of health, professional services and agriculture all performed well, with health growing strongly supported by the acquisition of Healthpoint. This was partly offset by the continued run down of the Auto finance portfolio to $2.1 billion. The sale of this portfolio was announced post balance date in October 2024; and • Deposits increased by 3% to $144.3 billion. Growth in term deposits of $2.4 billion and transaction accounts of $2.3 billion were partly offset by the decline in savings balances of $1.0 billion. Within the business segment, commercial and private wealth customer growth was more than offset by the reduction in balances across small and medium business customers from softer economic and trading conditions. Non-interest income down 5% • Non-interest income decreased 5% due to lower merchants income and trading activity. Expenses up 9% • Operating expenses were up 9%. Excluding the increase in litigation provisions, operating expenses increased 8% reflecting: – Higher salaries and wages and seasonality of employee costs; – Higher investment spend across the portfolio on the HealthPoint integration, UNITE and upgraded merchant terminals; and – Investment in business bankers to drive growth. Impairment charge of $47 million • The impairment charge of 9 basis points of average loans compared to 20 basis points in the prior period. The charge reflects higher new IAPs, which were partly offset by a small CAP benefit reflecting run off in the auto portfolio; and • Credit quality metrics deteriorated with stressed exposures to TCE up 4 basis points to 5.56%, mostly within the retail and wholesale trade sector. The proportion of impaired TCE increased 14 basis points to 0.68%.

Includes capital benefit and Bank Levy Net profit was up 1% to $686 million. Pre-provision profit decreased 5% to $993 million, reflecting flat operating income and a 7% increase in operating expenses. Flat operating income reflects balance sheet growth offset by lower sales and risk management income while the rise in operating expenses was driven by an increase in front line bankers to support growth and higher software amortisation costs. Net interest income up 6% • The net interest margin decreased 3 basis points reflecting an increase in trading securities in Markets related to reverse repurchase agreements. Excluding this, the net interest margin increased 5 basis points reflecting the benefit of higher interest rates on hedged capital and higher loan spreads. These impacts were partly offset by higher funding costs; • Average interest earning assets rose by 7% reflecting strong growth in lending and additional trading assets for Markets customers; • Net loans increased 8% to $100.6 billion driven by deepening relationships with existing customers, predominantly in the property, industrial and infrastructure sectors; and • Deposits increased 4% to $119.8 billion with an increase in term deposits and savings accounts partly offset by a decrease in transaction accounts. Term deposit growth reflects a strategy to deepen customer relationships. Non-interest income down 10% • Non-interest income decreased 10% to $599 million. Key drivers included: – Lower sales and risk management income from lower rates and FX trading; and – Lower fee income from the non-repeat of underwriting fees in the prior period. Expenses up 7% • Expenses increased 7% to $756 million reflecting: – An increase in front-line resourcing to support growth; and – Higher software amortisation costs from investments including payments. Impairment charge of $19 million • The impairment charge to average loans was 4 basis points, compared to a 22 basis point charge in the prior period. The charge reflects a small CAP charge largely from less favourable economics assumptions, which was partly offset by a small IAP benefit; and • Stressed exposures to TCE deteriorated 13 basis points to 0.76%, reflecting higher watchlist and substandard exposures in the services and property sectors. The proportion of impaired exposures to TCE remained flat at 0.05%. 1. DVA includes Funding Value Adjustment (FVA) and Credit Value Adjustment (CVA). Sales and risk management income includes both customer and non-customer income.

GROUP PERFORMANCE SEGMENT REPORTING 23 Westpac New Zealand (Continued) Net profit increased 21% to $578 million. Pre-provision profit increased 17% to $803 million, reflecting operating income growth of 7% and a decrease in operating expenses of 3%. Operating income benefited from a higher net interest margin while operating expenses fell as cost saving initiatives offset the impact of inflationary pressures. Net interest income up 6% • The net interest margin was up 12 basis points driven by improved lending spreads and the continued benefit from prior interest rate increases to transaction deposits and capital balances. This was partly offset by customers switching to higher yielding term deposits. • Net loans increased 1% to $102.1 billion, comprising business loan growth of 2% and home lending growth of 1%. Key drivers included: – Business lending growth was largely from corporate and institutional customers as larger businesses continued to have an appetite for credit. Subdued business confidence and softer economic activity impacted the appetite for credit across smaller businesses; and – Mortgages grew modestly due to a highly competitive environment. • Deposits increased 1% to $79.7 billion reflecting an increase in term deposits offsetting a decline in transaction and savings accounts. Consumer term deposits grew as customer preferences continued to shift towards higher yielding accounts, while business deposits remained flat. Non-interest income up 13% • Non-interest income increased 13% to $148 million driven by higher investment income and business fees. Expenses down 3% • Operating expenses decreased 3% to $674 million reflecting an increase in productivity initiatives and timing of investment spend. Expense decreases were partly offset by higher wages, vendor costs and amortisation. Impairment charge of $4 million • The impairment charge to average loans was 1 basis point, compared to a charge of 5 basis points in the prior period. The charge reflects higher IAPs mostly within the manufacturing sector, which was offset by small CAP benefits; and • Stressed exposures to TCE increased 18 basis points to 1.73% mostly due to deterioration in mortgage 90+ day delinquencies and higher impaired balances as consumers and businesses feel the stress of the challenging economic environment.

Average tangible ordinary equity Average ordinary equity less intangible assets (excluding capitalised software). Average total equity The average balance of shareholders’ equity, including non-controlling interests. Dividend payout ratio Current period ordinary dividend paid/declared on issued shares (net of Treasury shares) divided by the net profit attributable to owners of WBC (adjusted for RSP dividends). Earnings per ordinary share • Basic earnings per ordinary share is calculated by dividing the net profit attributable to owners of WBC by the weighted average number of ordinary shares on issue during the period, adjusted for treasury shares. • Diluted earnings per ordinary share is calculated by adjusting the basic earnings per ordinary share by assuming all dilutive potential ordinary shares are converted. Fully franked dividends per ordinary share (cents) Dividends paid out of retained profits which carry a credit for Australian company income tax paid by Westpac. Net tangible assets per share Net tangible assets (total equity less goodwill and other intangible assets less minority interests) divided by the number of ordinary shares on issue (less Treasury shares held). Pre-provision profit Net interest income plus non-interest income less operating expenses. Return on average ordinary equity (ROE) Net profit attributable to the owners of WBC adjusted for RSP dividends (annualised where applicable) divided by average ordinary equity. Return on average tangible ordinary equity (ROTE) Net profit attributable to the owners of WBC adjusted for RSP dividends (annualised where applicable) divided by average tangible ordinary equity. Weighted average ordinary shares Weighted average number of fully paid ordinary shares listed on the Australian Stock Exchange for the relevant period less Westpac shares held by Westpac (‘Treasury shares’). Productivity and efficiency Expense to income ratio Operating expenses divided by net operating income. Expense to income ratio (ex Notable Items) Operating expenses excluding Notable Items divided by net operating income excluding Notable Items. Full time equivalent employees (FTE) A calculation based on the number of hours worked by full and part-time employees as part of their normal duties. For example, the full time equivalent of one FTE is 76 hours paid work per fortnight. Revenue per FTE Total operating income divided by the average number of FTE for the period. Business Performance Average Where possible, daily balances are used to calculate the average balance for the period. Average interest bearing liabilities The average balance of liabilities owed by Westpac that incur an interest expense. Where possible, daily balances are used to calculate the average balance for the period. Average interest earning assets The average balance of assets held by Westpac that generate interest income. Where possible, daily balances are used to calculate the average balance for the period. Core NIM Calculated by dividing net interest income excluding Notable Items and Treasury & Markets (annualised where applicable) by average interest earning assets. Group NIM/Net interest margin Calculated by dividing net interest income (annualised where applicable) by average interest earning assets. Net profit Net profit attributable to owners of WBC. TSR Total shareholder return. Capital Adequacy Australian Prudential Regulation Authority (APRA) leverage ratio Tier 1 capital divided by ‘exposure measure’ and expressed as a percentage. ‘Exposure measure’ is the sum of on balance sheet exposures, derivative exposures, securities financing transaction (SFT) exposures and non-market related off balance sheet exposures. Common equity tier 1 (CET1) capital ratio Total common equity capital divided by risk weighted assets, as defined by APRA. Internationally comparable capital ratios Internationally comparable methodology references the ABA study on the comparability of APRA’s capital framework released on 10 March 2023. Risk weighted assets (RWA) Assets (both on and off-balance sheet) are risk weighted according to each asset’s inherent potential for default and what the likely losses would be in case of default. In the case of non-asset backed risks (i.e. market, IRRBB and operational risk), RWA is determined by multiplying the capital requirements for those risks by 12.5. Credit risk weighted assets (Credit RWA) Credit risk weighted assets represent risk weighted assets (on-balance sheet and off-balance sheet) that relate to credit exposures and therefore exclude market risk, operational risk, IRRBB and other assets. Tier 1 capital ratio Total Tier 1 capital divided by risk weighted assets, as defined by APRA. Total regulatory capital ratio Total regulatory capital divided by risk weighted assets, as defined by APRA.

28 WESTPAC GROUP 2024 SECOND HALF FINANCIAL PERFORMANCE REVIEW GLOSSARY OF ABBREVIATIONS AND DEFINED TERMS Funding and liquidity Deposit to loan ratio Customer deposits divided by net loans. High Quality Liquid Assets (HQLA) Assets which meet APRA’s criteria for inclusion as HQLA in the numerator of the LCR. Liquid assets HQLA and non LCR qualifying liquid assets, but excludes internally securitised assets that are eligible for a repurchase agreement with the RBA and the RBNZ. Liquidity Coverage Ratio (LCR) An APRA requirement to maintain an adequate level of unencumbered high quality liquid assets, to meet liquidity needs for a 30 calendar day period under an APRA-defined severe stress scenario. Absent a situation of financial stress, the value of the LCR must not be less than 100%. LCR is calculated as the percentage ratio of stock of HQLA, and qualifying RBNZ securities over the total net cash out-flows in a modelled 30 day defined stressed scenario. Net Stable Funding Ratio (NSFR) The NSFR is defined as the ratio of the amount of available stable funding (ASF) to the amount of required stable funding (RSF) defined by APRA. The amount of ASF is the portion of an ADI’s capital and liabilities expected to be a reliable source of funds over a one year time horizon. The amount of RSF is a function of the liquidity characteristics and residual maturities of an ADI’s assets and off-balance sheet activities. ADIs must maintain an NSFR of at least 100%. Term Funding Facility (TFF) A facility that was established by the RBA in March 2020 to provide 3 year term funding to Australian ADIs via repurchase transactions, subject to qualifying conditions, to help support lending to Australian businesses. The facility closed to new draw downs in June 2021. Wholesale funding Wholesale funding includes debt issues, loan capital, certificates of deposit, term funding from central banks and interbank placements. Credit quality Collectively assessed provisions (CAPs) Collectively assessed provisions for expected credit loss under AASB 9 represent the Expected Credit Loss (ECL) which is collectively assessed in pools of similar assets with similar risk characteristics. This incorporates forward-looking information and does not require an actual loss event to have occurred for an impairment provision to be recognised. Default Credit exposures that are non-performing. Gross impaired exposures provisions to gross impaired exposures Impairment provisions relating to impaired exposures include individually assessed provisions plus the proportion of the collectively assessed provisions that relate to impaired exposures. Impaired exposures Includes exposures that have deteriorated to the point where full collection of interest and principal is in doubt, based on an assessment of the customer’s outlook, cash flow, and the net realisation of value of assets to which recourse is held: • Facilities 90 days or more past due, and full recovery is in doubt: exposures where contractual payments are 90 or more days in arrears and the net realisable value of assets to which recourse is held may not be sufficient to allow full collection of interest and principal, including overdrafts or other revolving facilities that remain continuously outside approved limits by material amounts for 90 or more calendar days; • Non-accrual facilities: exposures with individually assessed impairment provisions held against them, excluding restructured loans; • Restructured facilities: exposures where the original contractual terms have been formally modified to provide for concessions of interest or principal for reasons related to the financial difficulties of the customer; • Other assets acquired through security enforcement (includes other real estate owned): includes the value of any other assets acquired as full or partial settlement of outstanding obligations through the enforcement of security arrangements; or • Any other facilities where the full collection of interest and principal is in doubt. Impairment charges/(benefit) to average loans Calculated as impairment charges (annualised where applicable) divided by average gross loans. Individually assessed provisions (IAPs) Provisions raised for losses on loans that are known to be impaired and are assessed on an individual basis. The estimated losses on these impaired loans is based on expected future cash flows discounted to their present value and, as this discount unwinds, interest will be recognised in the income statement. Non-performing not impaired exposures Includes those credit exposures that are in default, but where it is expected that the full value of principal and accrued interest can be collected, generally by reference to the value of security held. Performing exposures Credit exposures that are not non-performing. Stressed exposures Watchlist and substandard credit exposures plus non-performing exposures. Total committed exposure (TCE) Represents the sum of the committed portion of direct lending (including funds placement overall and deposits placed), contingent and pre-settlement risk plus the committed portion of secondary market trading and underwriting risk.

Internal charges and transfer pricing adjustments are included in the performance of each segment reflecting the management structure rather than the legal entity (these results cannot be compared to results for individual legal entities). Where management reporting structures or accounting classifications have changed, financial results for comparative periods have been restated and may differ from results previously reported. Overhead costs are allocated to revenue generating segments. Westpac’s internal transfer pricing frameworks facilitate risk transfer, profitability measurement, capital allocation and segment alignment, tailored to the jurisdictions in which Westpac operates. Transfer pricing allows Westpac to measure the relative contribution of products and segments to Westpac’s interest margin and other dimensions of performance. Key components of Westpac’s transfer pricing frameworks are funds transfer pricing for interest rate and liquidity risk and allocation of basis and contingent liquidity costs, including capital allocation.
