4 APS 330 Disclosure APS 330 Disclosure Australian Prudential Regulation Authority ( APRA ) has prudential oversight of the operations of all locally incorporated ADIs in Australia. Under Prudential Standard APS 330 Capital Adequacy: Public Disclosure of Prudential Information ( APS 330 ), ADIs that are Australian owned and have been approved by APRA to use the advanced approaches for the measurement of risk are required to disclose a range of both quantitative and qualitative prudential information annually, semiannually and quarterly. Certification and Disclosure The National Australia Bank Group s Chief Executive Officer attests to the reliability of the Group s APS 330 disclosures in the annual declaration provided to APRA under APS 310. Disclosure controls and procedures have been designed and implemented to effectively manage prudential reporting risk. The Group operates in multiple regulatory jurisdictions. The following table sets out the methodologies applied across the Group as at 31 March. Great Western Bank is reported under Standardised Other for the purposes of calculating the consolidated banking group position. This half year update of the Group s capital adequacy and risk disclosures has been prepared in accordance with APS 330. This report provides half year information on the quantitative tables required by APS 330 including: - Scope of Application - Capital Structure - Capital Adequacy Risk Weighted Assets and Capital Ratios - Credit Risk General Disclosures - Credit Risk Standardised Portfolio - Credit Risk IRB Portfolio - Credit Risk Mitigation - Securitisation - Traded Market Risk Standardised & IMA - Operational Risk - Equity Risk - Non-Traded Market Risk More detailed qualitative and quantitative disclosure of the Group s risk and capital disclosures for the year ended 30 September 2008 are available on the National Australia Bank Group s website ( The Group Disclosure and External Communications Policy (available on the National Australia Bank Group s website requires processes and practices to ensure the integrity and timeliness of prudential disclosures. 3

5 Scope of Application Scope of Application Scope of Disclosure As required under APS 330, this disclosure applies to the Level 2 consolidated Group, being the National Australia Bank Limited ( the Company ) and the entities it controls subject to certain exceptions set out in this part ( the Group ). The controlled entities in the Group include controlled banking entities (Bank of New Zealand, Clydesdale Bank PLC and Great Western Bank), and other financial entities (e.g. finance companies and leasing companies). Under guidelines issued by APRA, life insurance and funds management entities activities are excluded from the calculation of Basel II risk weighted assets and the related controlled entities are deconsolidated from the National Australia Bank Group for the purposes of calculating capital adequacy. Capital adequacy deductions are applied to the investments in, and profits of, these activities. In addition, securitisation special purpose vehicles ( SPVs ) to which assets have been transferred in accordance with APRA s requirements as set out in Prudential Standard APS 120: Securitisation ( APS 120 ) have been deconsolidated from the National Australia Bank Group for the purposes of this disclosure. For regulatory purposes credit risk is removed from the sold assets, and there is no requirement to hold capital against them. Differences arising in consolidation between Regulatory and Accounting approaches The primary difference in consolidation between the regulatory approach and the accounting approach as defined by the Australian equivalents to the International Financial Reporting Standards ( AIFRS ) is the area of investments in life insurance, funds management and securitisation. Under AIFRS, all entities, including special purpose vehicles, where the National Australia Bank Group has the power to govern the financial and operating policies so as to obtain benefit from their activities, are consolidated. This includes life insurance funds management and special purpose vehicles used to house assets securitised. A list of material controlled entities included in the consolidated National Australia Bank Group for accounting purposes can be found in the National Australia Bank Group s 30 September 2008 financial report. Restrictions on the transfer of funds or regulatory capital within the National Australia Bank Group The transfer of regulatory capital and funding within the National Australia Bank Group is subject to restrictions imposed by National Australia Bank Group or local regulatory requirements as reflected in internal policies. Scope of Application [APS 330 Table 1] Capital deficiencies in nonconsolidated subsidiaries Aggregate amount of under capitalisation in non-consolidated subsidiaries of the ADI group Clydesdale Bank PLC As at 31 Mar Sep 08 $m $m 0 0 Clydesdale Bank PLC has made use of the provisions laid down in BIPRU 2.1 (Solo Consolidation Waiver). This enables some intra group exposures and investments of Clydesdale Bank PLC in its subsidiaries to be eliminated and the free reserves of such subsidiaries to be aggregated, when calculating capital resource requirements of Clydesdale Bank PLC. BNZ Bank of New Zealand ( BNZ ) is a wholly owned subsidiary of National Australia Bank Limited and operates as a regionally autonomous, full-service bank in New Zealand. The BNZ Board is responsible for corporate governance and derives its authority from the Constitution of Bank of New Zealand and applicable New Zealand legislation. BNZ is subject to the capital adequacy requirements applicable in New Zealand, and achieved advanced Basel II status from the Reserve Bank of New Zealand ( RBNZ ) in The capital ratios for BNZ presented in this report have been derived under the RBNZ s Capital Adequacy Framework (Internal Models Approach). Full Basel II based disclosures are published separately under the General Disclosure Statement regime applicable to banks incorporated in New Zealand. Further, for funding transfers within the National Australia Bank Group, APS 222: Associations with Related Entities establishes limits on the level of exposure (for example debt and equity) that the Company may have to a related entity. National Australia Bank Group policy requires compliance with these limits and that the Company takes account of risks associated with dealings with other members of the National Australia Bank Group. 4

6 Capital Structure Capital Capital Adequacy [APS 330 Tables 3b f] The following table provides the Basel II risk weighted assets for the Group. Calculations are in accordance with APRA defined methodology. As at 31 Mar Sep 08 RWA RWA $m $m Credit Risk Corporate (including SME) (2) 156, ,395 Sovereign - - Bank 6,584 11,482 Residential mortgage 44,449 44,977 Qualifying revolving retail 4,610 4,537 Other retail 2,991 2,966 Other 6,585 6,965 Total (3) 221, ,322 Specialised lending (SL) exposures subject to slotting criteria (4) 21,598 14,675 Standardised approach Australian and foreign governments Bank 1, Residential mortgage 20,376 18,073 Corporate 37,921 40,008 Other 10,323 9,573 Total standardised approach 70,038 68,494 Other Securitisation 7,860 5,983 Equity Total credit risk 321, ,131 Market risk 5,121 5,088 Operational risk 24,336 23,649 Interest rate risk in the banking book 1,300 4,643 Total risk weighted assets (5) 352, ,511 Risk Weighted Assets ( RWA ) which are calculated in accordance with APRA's requirements under Basel II, are required to incorporate a scaling factor of 1.06 to assets that are not subject to specific risk weights. (2) The Group s Corporate portfolio includes all corporate credit exposures and exposures that could potentially fit a Retail SME portfolio, and as such contains a range from large corporates at the investment grade level to smaller retail SME customers. The Group has a large middle market corporate portfolio in its Australian portfolio. (3) For : Bank includes ADIs, overseas banks and non-commercial public sector entities. Residential mortgage includes exposures that are partly or fully secured by residential properties. Qualifying revolving retail exposures are revolving, unsecured and unconditionally cancellable (both contractually and in practice), for individuals and not explicitly for business purposes. Other includes non-lending asset exposures which are not covered in the above categories. Non-lending assets are specifically excluded from credit risk exposures shown on page 8 to 25 of this report. (4) Specialised Lending includes the four sub-classes: project finance, object finance, commodities finance and income producing real estate ( IPRE ). The majority of the increase in the Specialised Lending portfolio since 30 September 2008 is due to the reclassification of a number of counterparties from IRB Corporate (including SME) to Specialised Lending as part of an on-going portfolio review. (5) As at 31 March the Group held $4.0bn of government guaranteed Financial Institution Debt. The application of lower risk weights on these holdings resulted in a reduction of RWA by $1.2bn and an effective increase in Tier 1 capital ratio of 0.03% and Total capital ratio of 0.04%. This debt is assessed in accordance with normal credit approval processes. 5

The Level 2 group represents the consolidation of Group and all its subsidiary entities, other than non-consolidated subsidiaries as outlined under Table 1 Scope of Application. (2) Level 1 Tier 1 and total capital ratios for 30 September 2008 have been amended to reflect regulatory requirements for related party exposures to securitisation vehicles. Exposure to own asset securitisation vehicles at Level 1 was being captured when it should have been excluded as per the prudential guidelines. 6

The regulatory approach to calculating capital is different to the accounting approach as defined under AIFRS. 7

9 Credit Risk Credit Risk General Disclosure Summary Exposures by Measurement Approach [APS 330 Table 4i] This table provides the amount of gross credit risk exposure subject to the Standardised and Advanced es. The Group has no credit risk exposures subject to Foundation es. Gross credit risk exposure refers to the potential exposure as a result of a counterparty default prior to the application of credit risk mitigation. It is defined to be the outstanding amount on drawn commitments plus a credit conversion factor on undrawn commitments on a given facility. For derivatives, the exposure is defined as the mark-to-market value plus a potential value of future movements. Exposures exclude non-lending assets, equities and securitisation. Total exposure (EaD) Risk weighted assets As at 31 Mar 09 Regulatory expected loss Write-offs for the 6 months ended (2) Impaired facilities (3) Specific provisions (4) Exposure Type $m $m $m $m $m $m Corporate (including SME) 223, ,070 2, , Sovereign Bank 68,384 6, Residential mortgage 201,362 44, Qualifying revolving retail 11,596 4, Other retail 3,012 2, Other Total 508, ,704 3, ,915 1,073 Specialised lending (SL) 26,605 21, Standardised approach Australian and foreign governments 21, Banks 15,293 1, Residential Mortgage 33,259 20, Corporate 39,846 37, Other 10,304 10, Total standardised approach 120,510 70, Total exposures 655, ,340 4, ,924 1,277 General reserve for credit losses (5) 2,870 Total provisions for doubtful debts, excluding 4,147 assets at fair value General reserve for credit losses 2,870 Provision held on assets at fair value (6) 675 Collective provision 3,545 Regulatory expected loss is a calculation of the estimated loss that may be experienced by the Group by the over the next 12 months. (2) Write-offs represent credit loss expenses recognised in the Consolidated Income Statement during the reporting period in accordance with accounting rules. (3) Impaired facilities consist of retail loans (excluding credit card loans and portfolio managed facilities) which are contractually past due 90 days with security insufficient to cover principal and arrears of interest revenue; non-retail loans which are contractually past due and there is sufficient doubt about the ultimate collectability of principal and interest; and impaired off-balance sheet credit exposures where current circumstances indicate that losses may be incurred. Unsecured portfolio managed facilities when they become 180 days past due, and loans where some concerns exist as to the ongoing ability of the borrowers to comply with the present loan repayment terms, are classified as impaired assets. (4) Specific provisions for prudential purposes include all provisions for impairment assessed by an ADI on an individual basis in accordance with AIFRS. (5) The general reserve for credit losses for the purposes of this disclosure is calculated as the pre-tax collective provisions (excluding credit risk adjustments for fair value assets and trading derivatives). The collective provision being as disclosed in the National Australia Bank Group's Half Year Results. This will allow more relevant comparison to existing external disclosures. (6) The provisions held on assets at fair value at March. This excludes $39m of specific credit risk adjustments for assets at fair value and includes a management overlay of $160 million that has been taken in respect of conduit related assets and derivative transactions to reflect the uncertainty created by the rapid deteriorating economic conditions and the impact of any consequent default. 8

The Group s UK banking operations saw an increase in the commercial and residential property sectors, although the level of residential mortgages past due facilities 90 days remains less than half the UK industry average. Impaired facilities Impaired facilities increased by $1,775 million from September 2008 with the rise in the Group s Australia banking operations occurring mainly in business lending, with a broad variety of industries affected as a result of the economic downturn. In the Group s UK banking operations, gross impaired facilities have increased although relative to its local peer banks the Group continues to perform well. Residential mortgage impairments for the Group s UK banking operations continue to remain low. Increases in impaired facility levels in the Group s NZ banking operations have been mainly confined to business lending within the property and agriculture sectors. Residential mortgage impairments have also increased, however off a low base. The deterioration in credit conditions has affected nabcapital with a small number of high profile impairments being experienced in a broad variety of industries located in Australia and the UK. Charges for specific provisions Charges for specific provisions for the half year to March was $1,198 million (excluding Asset Backed Securities 'ABS' CDOs), relating to a small number of corporate impairments and smaller provisions spread across the corporate and residential mortgage asset classes. Write-Offs Increases in net write offs were experienced in the Group s Australian and UK banking operations, with a small number of large write offs in corporate asset classes. The write-off rate for other retail facilities has increased slightly, while residential mortgage write-offs remain negligible. 17
