Special Note Regarding Forward-Looking Statements

Certain statements under the captions “Highlights”, “Banking Analysis”, “Funds Management Analysis”, “Insurance Analysis”, “Shareholder Investment Returns” and elsewhere in this Profit Announcement constitute ‘forward-looking statements’ within the meaning of the U.S. Private Securities Litigation Reform Act of 1995. Such forward-looking statements, including economic forecasts, assumptions, business and financial projections, involve known and unknown risks, uncertainties and other factors. These factors may cause the actual results, performance or achievements of the Group to be materially different from any future results, performance or achievements expressed or implied by such forward looking statements. Such factors include demographic changes, changes in competitive conditions in Australia, New Zealand, Asia, the United States or the United Kingdom, changes in the regulatory structure of the banking, life insurance and funds management industries in Australia, New Zealand, the United Kingdom or Asia, changes in political, social, credit and economic conditions in Australia or New Zealand, legislative proposals for reform of the banking, life insurance and funds management industries in Australia, and various other factors beyond the Group’s control that may also affect the performance of the Group. Given these risks, uncertainties and other factors, investors are cautioned not to place undue reliance on such forward looking statements.

Financial Information Definitions

In addition to discussing the Australian equivalent to International Financial Reporting Standards (“AIFRS”) in this profit announcement, certain “non-GAAP financial measures” of the financial performance and results of the Group (as defined in SEC Regulation G) are included. These non-GAAP financial measures are not calculated in accordance with either AIFRS or US GAAP and are described below. This profit announcement contains reconciliations of these non-GAAP financial measures to our financial results prepared in accordance with AIFRS.

In this profit announcement, the Group presents its profit from ordinary activities after tax on a “statutory basis”, which is calculated in accordance with AIFRS. The Group also presents its results on a “cash basis”. “Cash basis” is defined by management as net profit after tax and minority interests, before treasury share valuation adjustments, defined benefit superannuation plan expense and one-off AIFRS hedging mismatch (refer to Note 2 to the Financial Statements, page 36). Management believes “cash basis” is a meaningful measure of the Group’s performance and provides the basis for the determination of the Bank’s dividends.

The Group presents certain results after adjusting for the impact of the sale of the Hong Kong Insurance Business – in relation to the profit on sale of that business, and the ongoing result of the insurance operations after excluding the financial results of the Hong Kong Insurance Business. Management believes presentation of results after these adjustments provides a more meaningful measure of the Group’s ongoing performance since the Hong Kong Insurance Business is no longer part of the Group’s business operations.

The Group also presents its earnings per share on a statutory basis and on a cash basis. Earnings per share on a statutory basis are affected by the impact of changes in the treasury share valuation adjustments, defined benefit superannuation plan expense, and the one-off AIFRS hedging mismatch. “Earnings per share (“cash basis”) is defined by management as net profit after tax and minority interests, before treasury share valuation adjustments, and defined benefit superannuation plan expense, and the one-off AIFRS hedging mismatch, divided by the weighted average of the Bank’s ordinary shares outstanding over the relevant period. This measure shows the “cash basis” net profit after tax, as described above, per share.

The Group presents its dividend payout ratio on a statutory and cash basis. The dividend payout ratio is calculated by dividing the dividends paid on ordinary shares by the net profit after tax (“statutory basis”), net of dividends on other equity instruments. The dividend payout ratio (“cash basis”) is calculated by dividing the dividends paid on ordinary shares by the net profit after tax (“cash basis”), net of dividends on other equity instruments. Similarly, the Group presents “Dividend cover – statutory”, which is net profit attributable to members of the Bank after dividends on other equity instruments divided by dividends on ordinary shares for the financial year, and “Dividend cover – cash”, which is net profit attributable to members of the Bank (“cash basis”) after dividends on other equity instruments divided by dividends on ordinary shares for the financial year. These ratios are provided on both a statutory and cash basis since net profit after tax, the primary component of these ratios, is also presented on a statutory and cash basis, for the reasons described above.

The Group presents an Adjusted Common Equity ratio (the “ACE ratio”). The ACE ratio is one measure considered by Standard & Poor’s in evaluating the Bank’s credit rating and is calculated in accordance with Standard & Poor’s methodology. The ACE ratio has been provided in response to an increased focus by equity analysts on this measure and to permit comparability by investors with other financial institutions. For the Group’s calculation of the ACE ratio refer to Appendix 8: Capital Adequacy.

Critical Accounting Policies and Estimates

Critical Accounting Policies and Estimates

The accounting policies followed in this Financial Report are the same as those applied in the Bank’s Annual Report on Form 20-F for the fiscal year ended 30 June 2006, refer to Note 1 for a summary of the Group’s significant accounting policies. Certain of these policies are considered to be more important in the determination of the Group’s financial position, since they require management to make difficult, complex or subjective judgements, some of which may relate to matters that are inherently uncertain. These decisions are reviewed by a Committee of the Board.

These policies include judgements as to levels of provisions for impairment for loan balances, actuarial assumptions in determining life insurance policy liabilities and pensions, and determining whether certain entities should be consolidated. An explanation of these policies and the related judgements and estimates involved is set out below.

Provisions for Impairment

Provisions for impairment are raised where there is objective evidence of impairment and at an amount adequate to cover assessed credit-related losses.

Credit losses arise primarily from loans but also from other credit instruments such as bank acceptances, contingent liabilities, financial instruments and investments and assets acquired through security enforcement.

Individually Assessed Provisions

Individually assessed provisions are raised where there is objective evidence of impairment and full recovery of principal is considered doubtful.

Individually assessed provisions are made against individual facilities in the credit risk rated managed segment where exposure aggregates to $250,000 or more, and a loss of $10,000 or more is expected. The provisions are established based primarily on estimates of the realisable (fair) value of collateral taken and are measured as the difference between the asset’s carrying amount and the present value of the expected future cash flows (excluding future credit losses that have not been incurred), discounted at the financial asset’s original effective interest rate. Short term balances are not discounted.

Individually assessed provisions (in bulk) are also made against statistically managed segments to cover facilities which are not well secured and past due 180 days or more, against the credit risk rated segment for exposures aggregating to less than $250,000 and 90 days or more past due, and against credit risks identified in specific segments in the credit risk rated portfolio. These provisions are derived primarily by reference to historical ratios of write-offs to balances in default.

Individually assessed provisions are provided for from the collective provision.

Collective Provision

All other loans and advances that do not have an individually assessed provision are assessed collectively for impairment.

The collective provision is maintained to reduce the carrying amount of portfolios of similar loans and advances to their estimated recoverable amounts at the Balance Sheet date.

The evaluation process is subject to a series of estimates and judgements.

In the credit risk rated segment, the risk rating system, including the frequency of default and loss given default rates, loss history, and the size, structure and diversity of individual credits are considered. Current developments in portfolios (industry, geographic and term) are reviewed.

In the retail statistically managed segment the history of defaults and losses, and the size, structure and diversity of portfolios are considered.

In addition, management considers overall indicators of portfolio performance, quality and economic conditions.

Changes in these estimates could have a direct impact on the level of provision determined.

The amount required to bring the collective provision to the level assessed is taken to the Income Statement as set out in Note 6 to the Financial Statements.

Life Insurance Policyholder Liabilities

Life insurance policyholder liabilities are accounted for under AASB 1038: Life Insurance Business. A significant area of judgement is in the determination of policyholder liabilities, which involve actuarial assumptions.

The areas of judgement where key actuarial assumptions are made in the determination of policyholder liabilities are:

• Business assumptions including:

• Amount, timing and duration of claims/policy payments;

• Policy lapse rates; and

• Acquisition and long term maintenance expense levels;

• Long term economic assumptions for discount and interest rates, inflation rates and market earnings rates; and

• Selection of methodology, either projection or accumulation method. The selection of the method is generally governed by the product type.

The determination of assumptions relies on making judgements on variances from long-term assumptions. Where experience differs from long term assumptions:

• Recent results may be a statistical aberration; or

• There may be a commencement of a new paradigm requiring a change in long term assumptions.

The Group’s actuaries arrive at conclusions regarding the statistical analysis using their experience and judgement.

Additional information on the accounting policies and the key actuarial assumptions can be found in the Bank’s Annual Report on Form 20-F for the fiscal year ended 30 June 2006.

Consolidation of Special Purpose Entities

The Group assesses whether a special purpose entity should be consolidated based on the risks and rewards of each entity and whether the majority of such risks and rewards pass to the Group. Such assessments are predominately required in the context of the Group’s securitisation program and structured transactions.

Critical Accounting Policies and Estimates

Pensions

The Group sponsors a range of superannuation plans for its employees world wide. The Group’s US GAAP disclosures of these plans are set out in Note 16 of the Bank’s Annual Report on Form 20-F for the fiscal year ended 30 June 2006. The Group expects the financing of these defined benefit plans will not materially affect its 2006/2007 cashflows.

The critical economic assumptions adopted to determine the defined benefit superannuation expense are the return on asset and discount rate assumptions.

The return on asset assumption is determined as the weighted average of the long term expected returns of each asset class, where the weightings are the benchmark asset allocations of the assets backing the defined benefit risks. The return on assets assumption for 2006/2007 is 8.25% pa (after tax).

A one percent increase in the return on assets assumption for the Officers’ Superannuation Fund (“OSF”) would decrease the Group’s 2006/2007 pension expense by $44 million (pre-tax) whilst a one percent decrease in the return on assets assumption would increase the 2006/2007 pension expense by $44 million (pre tax).

To align the reporting of the Group’s pension obligations under SFAS 87 “Employers’ Accounting for Pensions” with the requirements of AIFRS, effective from 30 June 2004, the discount rate assumption is based on the yield on 10 year Australian government securities. The discount rate assumptions will vary in line with market movements in the yield on 10 year Australian government securities. The discount rate assumption at 30 June 2006 was 5.8% pa. Under US GAAP, the fund liabilities are next determined at 30 June 2007.

A one percent increase in the discount rate assumption for the OSF would affect the Group’s AIFRS staff superannuation disclosures as follows:

• Decrease the 30 June 2006 fund liabilities by $400 million (pre tax);

• Increase the 2006/2007 pension expense by $8 million (pre tax);

• Correspondingly, a one percent decrease in the discount rate assumption for the OSF would affect the Group’s AIFRS staff superannuation disclosures as follows;

• Increase the 30 June 2006 fund liabilities by $501 million (pre tax); and

• Decrease the 2006/2007 pension expense by $6 million (pre tax).

International Financial Reporting Standards

On 1 July 2005 the Bank commenced application of the Australian equivalent of International Financial Reporting Standards (“AIFRS”). This was in line with the conversion deadline set out by the Financial Reporting Council of Australia.

Descriptions of the key AIFRS issues are set out in Note 1 (nn) of the Bank’s Annual Report on Form 20-F for the fiscal year ended 30 June 2006.

Critical Accounting Policies and Estimates

Significant US GAAP adjustments

For US GAAP reporting purposes a number of adjustments are required (see Note 18 to the Financial Statements) to reconcile AIFRS reported net profit, Shareholders’ Equity and total assets to US GAAP reported information. The more significant of these are;

• Derivatives – The Group does not seek to apply the hedge accounting rules applicable under US GAAP to all of the transactions for which hedge accounting has been applied under AIFRS. Therefore, many of the derivative hedges under AIFRS do not comply with the specific hedge criteria of US GAAP. In any given period this may result in a significant difference between reported profit under AIFRS and Net Income under US GAAP. The difference for the half year 31 December 2006 was an increase in Net Income of $1,053 million, and the difference for the half year ended 31 December 2005 was a decrease in Net Income of $983 million;

• Deconsolidation of Qualifying Special Purpose Entities (“QSPE”) - under AIFRS, entities are consolidated or deconsolidated based on whether majority voting rights are held, or exposure to rates and benefits. Under US GAAP the consolidation or deconsolidation of entities is subject to assessment under a different framework, which for securitisation of assets depends on an entity’s status as a “QSPE”. Certain entities consolidated under AIFRS have been deconsolidated under US GAAP, due to their status as QSPEs. The difference for the half year ended 31 December 2006 was a decrease in assets of $10,742 million (2005:$9,547 million).

• Life insurance – The methodology used for calculating life insurance and deferred acquisition costs is different under US GAAP compared to AIFRS (results in a $6 million increase in Net Income for the half year ended 31 December 2006, $2 million increase in Net Income for the half year ended 31 December 2005);

• Pensions – Under AIFRS the Group recognises movements in actuarial gains and losses directly in retained earnings, whereas under US GAAP the Group selected the “corridor” approach for their recognition in profit (results in a nil impact to Net Income for the half year ended 31 December 2006 and $1 million decrease in Net Income for the half year ended 31 December 2005).

Performance Highlights

	Half Year Ended

	$M		$M		$M
Net Profit after Income Tax		2,191		1,929		1,999

The Group’s net profit after tax (“statutory basis”) for the half year ended 31 December 2006 was $2,191 million, representing an increase of 14% on the prior half, and 10% on the prior comparative period.

The net profit after tax (“cash basis”) increased 14% on the prior half to $2,271 million, and 19% on the prior comparative period (excluding the profit on the sale of the Hong Kong Insurance Business of $145 million).

The Group’s Return on Equity has improved by 120 basis points on the prior half to 21.0% and by 10 basis points on the prior comparative period.

This was a strong result for the Group and reflects the Group’s focus on profitable product segments. The result was underpinned by:

• Strong growth in banking income, following growth in average interest earning assets of 9% to $307 billion since June 2006 and of 15% since December 2005, offset by net interest margin contraction of seven basis points since June 2006 and 17 basis points since December 2005;

• Growth in Funds under Administration of 11% to $168 billion on the prior half and 22% on the prior comparative period, supported by the continuing trends of both strong flows into the FirstChoice platform and strength in investment markets;

• Growth in planned profit margins and shareholder investment returns in the Insurance Business compared to both the prior half and prior comparative periods, as discussed on pages 24-27;

• Strong credit quality across all lending portfolios; and

• Operating expense growth of 4% on the prior half and 6% on the prior comparative period. Importantly, productivity improvements have enabled increased investment in the businesses including a significant investment in customer service staff.

The Group’s net profit after tax (“statutory basis”) for the half year was $2,191 million. The statutory result includes the impact of the following three non-cash items, which arose due to the requirements of Australian equivalents to International Financial Reporting Standards (“AIFRS”):

• Defined benefit superannuation plan income/(expense) which relates to the recognition of surplus superannuation fund assets ($4 million income);

• Treasury shares valuation adjustment which reflects the appreciation of the Bank’s own shares held in the life insurance statutory funds ($38 million expense); and

• One off AIFRS mismatch, a one off non-cash expense of $46 million which arose as a result of the expiry of a hedging transaction. The offsetting gain was recognised as an adjustment to opening retained earnings on the adoption of AIFRS on 1 July 2005. No economic loss has been incurred by the Group. Refer to Note 2 Income from Ordinary Activities, page 36 for more information.

Dividends

The interim dividend for the year is $1.07 per share, an increase of 13 cents or 14% on the prior comparative period, representing a dividend payout ratio (“statutory basis”) for the half year of 63.8%, and a dividend payout ratio (“cash basis”) for the half year of 61.5%.

The dividend payment is fully franked and will be paid on 5 April 2007 to owners of ordinary shares at the close of business on 23 February 2007 (“record date”). Ordinary shares will be quoted ex–dividend on 19 February 2007.

The Group issued $300 million of shares to satisfy shareholder participation in the Dividend Reinvestment Plan (“DRP”) in respect of the final dividend for 2005/06.

Outlook

The discussion below includes forward-looking statements. See “Special Note Regarding Forward-Looking Statements”.

The Australian economy has maintained a good level of growth during the first half of the 2007 fiscal year. Looking forward, growth is likely to remain below the levels experienced in recent years due to capacity constraints and the impact of the drought on the economy. Business credit growth remains solid and consumer spending has been resilient in a rising interest rate environment.

The Australian financial services industry continues to be highly competitive.

The Group has maintained good earnings and strong credit quality over the first six months of the 2007 financial year. Given the positive economic outlook and the diversity of the income streams, the Group believes it remains on track to deliver cash EPS growth which meets or exceeds the average of its peers.

Financial Performance and Business Review

Performance Highlights

The half year net profit after tax (“statutory basis”) of $1,825 million for the Banking business increased 12% on the prior half and 16% on the prior comparative period.

The performance during the half year was driven by:

• Continued strong volume growth in home loans, driven by the continued high demand for housing finance, up 7% since June 2006 to $166 billion, and up 10% since December 2005;

• Improvement in business lending volumes, up 11% since June 2006 to $84 billion, and up 18% since December 2005 driven by the general business credit growth in the Australian market;

• Australian deposit volume growth of 7%, since June 2006 to $161 billion, and 11% since December 2005 driven by the current interest rate environment;

• Net interest margin decreased seven basis points over the half year and 17 basis points over the full year largely due to changes in asset and funding mix together with the impact of competition on the home loan and credit card portfolios;

• Investment in front line staff and salary increases, offset by productivity increases, resulting in an operating expenses increase of 2% on the prior half and 4% on the prior comparative period;

• Credit quality remaining strong.

More comprehensive disclosure of business highlights by key product category is contained on pages 15-20.

Net Interest Income

Net interest income increased by 7% on the prior half to $3,485 million and 7% on the prior comparative period. The growth was driven by a strong increase in average interest earning assets of 9% offsetting a seven basis point reduction in net interest margin for the prior half and a 17 basis points reduction for the prior comparative period.

Average Interest Earning Assets

Average interest earning assets increased by $24 billion on the prior half to $307 billion, reflecting an almost $20 billion increase in average lending interest earning assets and an over $4 billion increase in average non-lending interest earning assets. Average interest earning assets increased by $40 billion on the prior comparative period. The increases in both periods were primarily driven by home lending and term lending growth.

Home lending growth continued to be the largest contributor to the increase in average interest earning assets driven by the continued high demand for housing finance. Average home loan balances have increased by 7% since 30 June 2006 and 11% since December 2005.

Personal Lending average balances have increased by 7% since June 2006 and 10% since December 2005. This result has been driven by strong growth in margin loans. Credit card growth has been subdued largely due to the decision not to match the zero rate balance transfers offered by certain competitors.

Average balances for Business, Corporate and Institutional lending have increased 11% since June 2006 and 18% since December 2005 reflecting growth in structured finance and general business lending.

Net Interest Margin

Net interest margin of 2.22% decreased seven basis points on the prior half (decreased 17 basis points on the prior comparative period), comprising a three basis point decline due to growth in liquid assets and a four basis point contraction in core lending and deposits. At a summary level, the margin contraction is attributable to the Group’s strategy of pursuing profitable growth in a competitive environment. The strategy has driven changes in business mix by focusing on quality lending growth while foregoing growth in products with low long-term value creation.

Excluding the volatility associated with AIFRS (one basis point contraction on the prior comparative period only), the net interest margin contraction was due to:

Pricing: Changes driven by margin contraction within home loan lending (two and half basis points for the prior period, and five and a half basis points on the prior comparative period); business lending (four basis points on the prior comparative period); and credit cards (one and a half basis points on both periods).

Cash Rate: Deposit margin improvement for both the half year and prior comparative period has contributed a net increase of three basis points. This is partly offset by margin contraction due to the timing lag that arises on passing cash rate increases on to variable rate home loans (half basis point); the impact on credit card balances not bearing interest (half basis point); and the tightening of spreads due to the 90-day bill rate rising in anticipation of cash rate increases during the period (one basis point).

Funding mix: Average lending asset growth of 8% in the prior half (12% on prior comparative period) continued to outpace average retail deposit growth of 4% in the prior half (9% on prior comparative period). This resulted in a greater reliance on wholesale funding which has grown from 45% in both December 2005 and June 2006 to 46% in December 2006. This ongoing structural change in funding mix has resulted in a two basis point margin contraction over both the prior half and prior comparative period.

Lending Mix: Higher margin business lending has grown faster than lower margin home lending, resulting in a one basis point increase in margin over both the prior half and prior comparative period.

Liquid Assets: Average non lending assets have increased by over $4 billion on the prior half and $6 billion on the prior comparative period resulting in margin reduction of three basis points for the half and five basis points on the prior comparative period.

Additional information, including the average balance sheet, is set out on pages 73 to 74.

Other Banking Income

Factors impacting other banking income were:

• Commissions: increased by 5% on both the prior half and the prior comparative period to $859 million, principally driven by increased home lending package fee income and continued strong brokerage commissions within CommSec;

• Lending fees: increased by 1% on the prior half to $417 million and by 7% on the prior comparative period. The result was driven by growth in institutional lending offset by seasonal factors in other fee categories. Increases in establishment fees received due to lending volume growth no longer flow through other banking income; the benefit is instead received within net interest income over the life of the product under AIFRS;

• Trading income was up 17% on the prior half and 25% on the prior comparative period to $306 million due to favourable market conditions and an increase in trading assets; and

• Other income increased $21 million on the prior half and $122 million on the prior comparative period. The current half year includes $79 million due to the sale of the Bank’s share in Greater Energy Alliance Corporation Pty Limited (“Loy Yang”). The prior half year included $32 million received from the sale of equity in the Mastercard IPO.

Banking Analysis

Operating expenses

Operating expenses within the Banking business increased by 2% on the prior half to $2,354 million and by 4% on the prior comparative period. Operating expenses were impacted by:

• Average salary increases of 4% during the past twelve months reflecting labour market tightness and increases in other inflation-related expense;

• Investment in front line staff, in both periods, supporting the banking operations with 577 new Australian retail customer service staff recruited since October 2005 together with the reintroduction of business bankers in the branches;

• Continued investment in projects supporting the strategic priorities of the Bank, in both periods, (including customer service and business banking initiatives); partly offset by

• IT efficiency savings and favourable timing differences in advertising and other spend, which occurred during the prior period.

Banking Expense to Income Ratio

Banking expense to income ratio improved from 47.4% for the half year ended June 2006 (and from 48.1% for the half year ended December 2005) to 45.6% in the current half representing a productivity improvement of 4% over the prior half and 5% over the prior comparative period. The improvement reflects strong income growth and good expense control, including IT efficiency savings.

Loan Impairment Expense

The total charge for loan impairments for the half year was $195 million, which represents 17 basis points of Risk Weighted Assets on an annualised basis. This expense is $15 million lower than the prior half reflecting continued improvement in the quality of the unsecured lending portfolio. When compared against the prior comparative period, this expense is $7 million higher due to increased write-offs in the unsecured lending portfolio.

Gross impaired assets were $338 million as at 31 December 2006, compared with $326 million at 30 June 2006 and $396 million at December 2005.

The Bank remains well provisioned, with total provisions for impairment as a percentage of gross impaired assets of 364%, as at 31 December 2006.

Taxation Expense

The corporate tax charge for the half year was $734 million, an effective tax rate of 28.1%. This compares to tax of $691 million (29.5% effective tax rate) for the prior half and $648 million (28.8% effective tax rate) for the prior comparative period.

Provisions for Impairment Losses

Total provisions for impairment losses at 31 December 2006 were $1,230 million. The current level reflects:

• The credit quality of the home lending and business lending portfolios; and

• Improvement in the credit quality of the unsecured retail lending portfolio due to tightening of credit policies since 2004.

Banking Analysis

Australian Retail

The Australian Retail product segment continued to perform strongly over the half year ended 31 December 2006, with profit after tax increasing by 8% on both the prior half and on the prior comparative period. The result was underpinned by revenue growth of 4% on both the prior half and on the prior comparative period, in a competitive business environment, expense management and continuing sound credit quality.

Business Review

Over the half year, good progress was made on a number of initiatives designed to improve the customer experience, to enable the Group to achieve its vision to be Australia’s finest financial services organisation through excelling in customer service. Highlights in the half year included:

• The recruitment of a further 127 customer service staff, taking the number of new front line customer service positions established since October 2005 to 577;

• A fresh approach to the recruitment, induction and training of new customer service staff, with greater emphasis placed on the service and sales skills of our people;

• The continued reinvigoration of front line service and sales effort through global best practice techniques and processes;

• The opening of new branches in selected growth areas, with new technology and design features delivering a better experience for customers;

• The opening of 65 of the busiest branches for Saturday trading;

• The ongoing revitalisation of the product range; and

• The continued utilisation of the Group’s state-of-the-art customer management system, CommSee, to improve sales productivity and customer service.

As a result of these and other actions, there have been some encouraging improvements in a range of customer service and people engagement measures, including;

• Customer satisfaction levels have improved from 75.1% to 80.0% since June 2006 (Source: AC Nielsen, Financial Institution Customer Monitor (Q3) September 2006 survey); and

• Improving trends in key measures of staff engagement, including absenteeism and time lost through injury.

Home Loans

Home loan revenue increased by 4% on the prior half. Net interest income grew by 3% on the prior half, with strong average balance growth of 4% partially offset by lower margins. Similarly home loan revenue increased by 3% on the prior comparative period. Net interest income grew by 2% with strong average balance growth of 11% partially offset by lower margins. Margin compression in the period was largely due to mix changes relating to a higher proportion of lower margin package and fixed rate lending. Fixed rate margins were compressed by yield curve changes in the periods leading up to the August and November cash rate rises. Fee revenue growth was solid, underpinned by good fee income from bundled products.

Some market share has been ceded over the period, largely to smaller players generating a greater proportion of their business through the broker distribution channel. There has been some dampening in consumer demand following rises in official interest rates, particularly in the first home buyer and investor housing segments.

Consumer Finance (Personal Loans and Credit Cards)

Total income in the Consumer Finance portfolio was 3% lower on the prior half and flat on the prior comparative period, with the prior half including $32 million received from the sale of equity in the MasterCard IPO. Excluding this, income growth was 2% on the prior half. Credit card income has come under pressure in an increasingly price-driven market, characterised by zero/low rate balance transfer offers and strong growth in the low rate card segment. The Bank’s low-rate credit card (“Yellow”) continues to meet strong customer demand, with over 174,000 accounts opened since launch in March 2006.

Retail Deposits

Retail deposits include all Australian retail customer transaction and savings accounts and other demand deposits. Deposit revenue increased 6% on both the prior half and prior comparative period, driven by a combination of strong volume growth and improved margins in a rising interest rate environment.

Deposit balances grew by 6% on the prior half to $97 billion, and 8% over the prior comparative period. Increased inflows were recorded in a range of products, including Transaction Accounts, NetBank Saver and Term Deposits. NetBank Saver balances now stand at over $6 billion, accounting for 7% of total portfolio balances.

Operating expenses

Expenses increased by 2% to $1,206 million on the prior half and are flat compared to the prior comparative period. Expense growth in this period reflects staff related pay increases from 1 July 2006 and the introduction of additional front line customer service staff. Offsetting this has been the continuing realisation of productivity and other expense savings.

Loan Impairment

Total Loan Impairment Expense for retail products for the half year was $164 million, a reduction on the prior half of $34 million and an increase of $8 million on the prior comparative period. Lower collective provisioning levels reflect an improvement in unsecured consumer portfolio arrears. Overall credit quality in the consumer portfolios remains sound. Home loan and credit card loss rates are stable and whilst home loan arrears rates have risen in line the market, this is off a very low base. In personal loans, policy tightening and the introduction of new scorecards has resulted in an improvement in loan credit quality.

Banking Analysis

Business, Corporate and Institutional

The Business, Corporate and Institutional product segment delivered net profit after tax of $762 million, an increase of 24% on the prior half and an increase of 29% on the prior comparative period. Included in the current half is a $55 million after tax profit on the sale of the Bank’s share in Greater Energy Alliance Corporation Pty Limited (“Loy Yang”). Excluding this amount, profit increased 15% on the prior half and 20% on the prior comparative period.

Business Review

The Business, Corporate and Institutional product segment performed well with the performance highlights including:

• A five year expansion and change program has been launched as the “Business Banking Growth Strategy”. Execution of the program is progressing to plan including alignment of the internal business segments with our customer needs. The recruitment of business bankers into branches throughout the country has commenced. The first new Business Banking Centre was opened in Western Australia in December 2006 and plans are on track for continuing expansion of the distribution footprint to establish a presence in key growth areas. A comprehensive training and development program is being rolled out to all of the front line staff and new recruits with approximately 50% of front line staff having completed the first stage of the program.

• Institutional Banking achieved above market growth rates in both periods.

• CommSec is Australia’s largest stockbroker with more than one million clients as well as the most active broker by number of transactions on the ASX, recently averaging more than 35,000 transactions per day (October 2006). The CommSec website is the number one site for stocks and shares in Australia, receiving more than 400 million hits per month and transferring more than 11 terabytes of data. The Group was the only major bank to participate, as a member of the syndicate, in the T3 offering and have been experiencing favourable growth in Equity Capital Markets and margin lending.

• The rollout of CommBiz, an internet-based banking channel for business customers, is gathering pace. Feedback from the early adopter customers has been very positive with strong endorsement of the service efficiency, functionality and intuitive user interface. The first external customer commenced using CommBiz in October and the solution was launched in December. Around 400 business customers are now using CommBiz and over $1 billion of payments have been processed.

• The Financial Markets and Treasury functions have been brought together to obtain better leverage across the financial markets operations and provide a platform for future growth opportunities.

Outcomes by key product category are summarised below.

Corporate Banking

Corporate Banking includes commercial and corporate transaction services and merchant acquiring.

This line of business achieved income growth of 11% on the prior half and 6% on the prior comparative period reflecting deposit balance growth largely driven by the introduction of the Business Online Saver product; seasonal merchant income increases; and the benefit of the recent interest rate rises.

Financial Markets

Financial Markets includes financial markets and wholesale operations, treasury, equities broking (including CommSec) and structured products, capital markets services (including IPOs and placements) and margin lending.

Financial markets income has increased 8% on the prior half and 10% on the prior comparative period following continued favourability in trading conditions and increased customer flows. Growth in investment markets has also resulted in increased CommSec trading volumes and margin lending balances have increased 14% on the prior half.

Lending and Finance

Lending and Finance includes asset finance, structured finance and general business lending.

Lending and Finance income has increased by 15% on the prior half and 29% on the prior comparative period. Income volatility has been impacted by the timing of asset sales including the $79 million pre-tax profit on sale of the Bank’s share in Greater Energy Alliance Corporation Pty Limited (“Loy Yang”) during the half.

Lending and Finance assets have increased $9 billion or 9% on the prior half and $16 billion or 17% on the prior comparative period. The increase has been driven by continued growth in the Australian and New Zealand syndicated loan market and in structured finance transactions.

Operating Expenses

Operating expenses of $833 million increased by 3% on the prior half and by 4% on the prior comparative period. This was due to general salary increases and higher employee numbers, mainly to support the expansion of the Business Banking activities.

Market Share

Business lending market share to non-financial corporations, as measured by APRA, has increased by 40 basis points since 30 June 2006 and is flat since 31 December 2005. However, the broader RBA business lending market share measure has declined by 20 basis points to 12.9% over this period and by 50 basis points since 31 December 2005.

Asset Finance market share has decreased by 60 basis points to 13.9% since June 2006 and by 120 basis points since December 2005. The decline reflects the maturity of this business segment, which has been characterised by aggressive price competition coupled with competitor expansion.

Business deposit market share of non-financial corporations, as measured by APRA, has increased by 10 basis points since 30 June 2006.

Equities Trading market share has remained constant over the calendar year at 4.3%.

Banking Analysis

Asia Pacific

Asia Pacific Banking incorporates the Group’s retail, business/commercial and rural banking operations in New Zealand, Indonesia, China and Fiji.

Net profit after tax for the Asia Pacific businesses increased 9% to $202 million compared to the prior half and by 10% on the prior comparative period. ASB Bank in New Zealand represents the majority of the business.

ASB Bank

ASB Bank net profit after tax for the half year was $195 million, an increase of 8% on the prior half year and 6% on the prior comparative period. The major drivers of growth were:

• Continued high demand for housing finance leading to a 6.8% increase in average home loan balances since June 2006 (14% on the prior comparative period), driven by the high demand for housing finance. This enabled the business to maintain market share of home loans at 23.1% for the half year (23.2% for the prior comparative period);

• Retail deposit balances of $20.4 billion were 8% higher than at 30 June 2006 (17% higher than the prior comparative period). FastSaver and the new BusinessSaver accounts continue to grow strongly collectively representing 72% of total retail deposit growth for the half year (62% on the prior comparative period) driven by the current interest rate environment;

• Reduction in net interest margin of seven basis points, against both periods, arising from increased mix of high interest rate deposits and competitive pressure on asset prices;

• Expansion of the ASB service capability across New Zealand with three new branches opened in the half year; and

• Improvement in loan arrears versus both periods, primarily within the Home and Personal Lending sectors.

Other Asia Pacific Business

The highlights in this region during the half were:

• The Group made an offer to acquire 83% of a regional bank, Arta Niaga Kencana (ANK), in the Surabaya region of Indonesia. ANK has 20 branches to add to the existing 21 branches which PT Bank Commonwealth operates in Jakarta. The acquisition is subject to regulatory and shareholder approvals. This is not expected to have a material financial impact on this region’s results;

• The two investments in China City Commercial Banks, Hangzhou and Jinan, continue to perform well. Profit momentum has been maintained in Hangzhou and the dividend payout ratio for Jinan has now increased to 6% of paid up capital;

• Capability transfer programs for Jinan City Commercial Bank are well advanced and such programs have also commenced in Hangzhou City Commercial Bank;

• Purchase of an additional 14 million shares for $5.8 million in Hangzhou City Commercial Bank to maintain the Group’s shareholding at 19.9% following an issue of shares to the Asian Development Bank; and

• Fiji lending balances grew by 6.7% to $377 million during the half year ended 31 December 2006. A tightening of the liquidity situation in Fiji, due to current political developments there, pushed up cost of funds and negatively impacted margins during the period.

Market Share

Housing lending market share in New Zealand remained flat against the prior half at 23.1%, and was down nine basis points against the prior comparative period, despite intense competition in this market.

Retail deposit market share in New Zealand was 20.7%, up from 20.3% at 30 June 2006, and 19.9% at 31 December 2005.

Funds Management Analysis

Financial Performance and Business Review

Performance Highlights

Net profit after tax (“statutory basis”) of $197 million increased by 19% on the prior half and 36% on the prior comparative period reflecting continued strong revenue growth.

Half year net profit after tax (“cash basis”) increased 6% on the prior half and 25% on the prior comparative period.

Business Review

Industry conditions have remained positive with strong investment markets and retail flows driving growth.

Funds under administration (FUA) increased by 11% on the prior half to $168 billion and 22% on the prior comparative period. The growth in Funds under Administration has primarily been driven by strong investment performance (refer to table on page 22).

Net funds inflows in the half year ended 31 December 2006 were $2.1 billion (compared to $8.1 billion in the prior half and $2.7 billion in the prior comparative period). The prior half net inflows of $8.1 billion were boosted by $4.3 billion of inflows related to a one-off FUA acquisition.

The key drivers of net funds flows, excluding the $4.3 billion of inflows related to a one off FUA acquisition, were:

• Continued flows into the FirstChoice platform in both periods;

• Institutional and international flows generated by the Global Asset Management business in both periods;

• Some outflows from Income and Mortgage Funds to high yielding banking products following recent interest rate rises in both periods; and

• Reduction in Property net out flows following the transfer of management rights in the Commonwealth Property Fund ($0.9 billion) and the sale of the Colonial Agricultural Fund ($0.3 billion) in the prior period.

FirstChoice flows remained strong in the market with $3 billion in net flows for the half year ended 31 December 2006. With over $31 billion in Funds under Administration FirstChoice has experienced a growth rate of 48%, in FUA, in the last 12 months. A recently published survey from ASSIRT showed that 57% of advisors in the market used FirstChoice as one of their platforms.

Market Share

In the latest Plan for Life market share statistics, the Group ranked 1^st in retail net flows for the year to September 2006. The Group remains 1^st in total retail market share at 15.3%.

Other key developments within the business include:

• CFS Global Asset Management is the joint lead partner in a consortium acquiring AWG plc; an infrastructure company with enterprise value in excess of £5 billion. The principal business is Anglian Water, the UK’s largest water and wastewater company by service area. The company was delisted from the London Stock Exchange on 21 December 2006. The consortium has reached the 92% acceptance threshold and has moved to compulsory acquisition of the remaining shares. Refer to Note 11 for additional information;

• New Products launched by CFS Global Asset Management during the period include the Long Short Energy Fund, Asian Property Securities Fund and the India Sub-continent Fund;

• Continued progress with initiatives designed to improve cross-selling of Wealth Management products to retail customers, and the focus now shifting to realisation of benefits;

• Successful implementation of the new Financial Wisdom Dealer Group Offering, which comprised third party financial advisers, in October to enhance practice quality and adviser segment service levels.

Investment Performance

Investment performance has been solid with 72% of funds outperforming benchmark for the half year to 31 December 2006. On a one year basis, 66% of funds have outperformed benchmark; and 61% of funds have outperformed on a three year basis. Relevant benchmarks are determined by the Group using industry guidelines on a fund by fund basis and the determination is dependant on fund objectives, asset class and investment strategies.

Operating Income

Operating income increased by 8% to $898 million on the prior half, up 25% on the prior comparative period. Underpinning this result was an increase in average funds under administration of 7% on the prior half and 21% on the prior comparative period.

Margins remained steady over the half, with performance fees and growth in higher margin asset classes offsetting the impact of outflows in higher margin legacy business.

Operating Expenses

Total operating expenses of $567 million were up by 7% on the prior half and 24% on the prior comparative period.

The primary drivers of expense growth include:

Volume related expenses of $144 million, up 15% on the prior half and 45% on the prior comparative period:

• Commission expenses increasing in line with funds under administration; and

• Increased performance-based commissions to property trusts.

Other significant drivers of expense growth include:

• Increased spend on strategic projects including the Wealth Management cross-selling initiatives;

• Increase in performance-based remuneration to retain and attract high quality talent within the asset management business;

• Expenses relating to the full impact of businesses acquired (being the Gandel joint venture property management interests) during the previous financial year; and

• Offset by reduced compliance spend in this half on the unit pricing initiative which is tracking well.

Taxation

The effective corporate tax rate for the half year was 29.9% compared with 28.2% for the prior half which included the benefit of recouped international tax losses, and 28.7% in the prior comparative period.

Financial Performance and Business Review

Performance Highlights

Net profit after tax (“statutory and cash basis”) of $169 million for the Insurance business increased 28% on the prior half and decreased 40% on the prior comparative period, which included $145 million profit on sale of the Hong Kong Insurance Business. These growth rates were affected by the positive experience variations of $29 million which occurred in the prior half, and by the inclusion of the operating results of the Hong Kong Insurance Business for part of the prior comparative period. Management believes that a better measure of Insurance business performance is planned profit margins, which increased by 22% on the prior half and 36% on the prior comparative period.

The result for both periods was driven by:

• Inforce premium growth in Australia and New Zealand;

• Growth in planned margins; and

• Increase in investment spend in the business.

Statutory profit after tax increased by 28% on the prior half, a strong result driven by high shareholder investment returns.

The Bank remains the largest life insurer in Australia based on total risk market share (Source: Plan for Life), and New Zealand based on inforce premium market share growth (Source: ISI statistics).

Business Review

Australia

Half year ended 31 December 2006 net profit after tax (“statutory and cash basis”) increased 26% to $115m reflecting growth in shareholder returns. The result for the half increased 26% on the prior comparative period.

Key performance drivers were:

• Life and General Insurance premium growth, with inforce premiums increasing by 15% (16% on the prior comparative period), reflecting strong sales volumes;

• Increase in planned life margins of 9% on the prior half and 42% on the prior comparative period;

• Good claims experience, particularly in the Group Risk portfolio for both periods; and

• Very strong shareholder investment returns in both periods.

Other highlights for the Australian Insurance business include:

• Increased market share for Australian risk premiums to 13.7% of the total insurance risk market and maintaining its number 1 position as at September 2006;

• The introduction of 73 Branch Insurance Representatives as part of the cross-selling initiative positively impacting on General Insurance sales;

• Ongoing simplification and rationalisation of systems and processes;

• Launch of online quoting tool for planners aimed at reducing the time and complexity of insurance and annuity quotes to improve conversion rates; and

• Continued good claims management.

New Zealand

The life insurance operations in New Zealand operate predominantly under the Sovereign brand.

New Zealand’s net profit after tax (“statutory and cash basis”) was $50 million for the half year ended 31 December 2006, an increase of $4 million over the prior half and $2 million over the prior comparative period. The main drivers of this result were:

• Market leading growth in new business sales with Sovereign capturing 33.8% of New Business sales market share for the December 2006 quarter compared to 32.7% for the half year ended 30 June 2006 and 32.6% for the half year ended 31 December 2005; and

• A continuation of positive investment returns offset by higher claims incidence in disability and term life.

The market share of inforce premiums at 31 December 2006 was 31.5%, an increase of 12 basis points over 30 June 2006, and 59 basis points over 31 December 2005.

Operating Income

Total operating income increased 7% on the prior half to $382 million and is down 1% on the prior comparative period. The prior comparative period is impacted by the inclusion of the operating results of the Hong Kong Insurance Business until its sale in October 2005 ($42 million). Excluding this, total operating income increased 11% on the prior comparative period.

Life Insurance income increased 5% on the prior half in line with average inforce growth (down 2% on the prior comparative period, which includes the Hong Kong operating results). The quality of the result improved with a higher component of planned margins.

General Insurance income increased 26% on the prior half and 10% on the prior comparative half. The result was supported by an increase in sales and no significant weather events. The prior half included weaker claims experience associated with Cyclone Larry.

Operating Expenses

Total operating expenses of $228 million increased by 12% on the prior half (down 10% on the prior comparative period) with investment spend aimed at future revenue growth driving this increase.

The prior comparative period is impacted by the inclusion of the operating results of the Hong Kong Insurance Business until its sale in October 2005 ($33 million). Excluding this, total operating expenses increased by 4% on the prior comparative period.

Increases in operating expenses for both periods include:

• Increased spend on strategic projects including the Wealth Management cross-selling initiatives;

• Introduction of Branch Insurance Representatives into selected Bank branches;

• Product development across life and general insurance lines;

• Investment on system migration to further reduce the number of insurance systems used in order to reduce ongoing costs; and

• Development costs in preparation for the launch of compulsory savings in New Zealand under the KiwiSaver program.

Corporate Taxation

The effective corporate tax rate for the half year was 28.1% compared with 27.9% in the prior half and 26.8% in the prior comparative period.

Excluding the $145 million profit on sale of the Bank’s Hong Kong life insurance business, shareholder investment returns increased by 149% on the prior comparative period.

Review and Results of Operations

Commonwealth Bank recorded a statutory net profit after tax of $2,191 million for the half year ended 31 December 2006, compared with $1,999 million for the prior comparative period, an increase of 10%. Excluding the $145 million profit on sale of the Hong Kong Insurance Business that was recognised in the prior comparative period, the profit growth was 18%. The increase was principally due to strong growth in banking income resulting from lending asset growth, as well as continued strong performance within the Funds Management and Insurance Businesses.

The net profit from Banking of $1,825 million (December 2005: $1,570 million), reflects continued growth in home loans and business lending together with strong credit quality.

The net profit from Funds Management of $197 million (December 2005: $145 million) reflects growth in revenues from a 21% increase in average funds under administration on the prior comparative period. Insurance reported a net profit of $169 million (December 2005: $284 million). Excluding the profit on sale of the Hong Kong Insurance Business from the prior comparative period, this represents profit growth of 22%.

In accordance with the ASX Principles of Good Corporate Governance and Best Practice Recommendations, the Chief Executive Officer and the Chief Financial Officer, have provided the Board with a written statement that the accompanying Financial Report represents a true and fair view, in all material respects, of the Bank’s financial position as at 31 December 2006 and performance for the half year ended 31 December 2006, in accordance with relevant accounting standards.

Signed in accordance with a resolution of the Directors.

Note 1 Accounting Policies

General Information

The Financial Statements of the Commonwealth Bank of Australia (the ‘Bank’) and the Bank and its subsidiaries (the ‘Group’) for the half year ended 31 December 2006, were approved and authorised for issue by the Board of Directors on 14 February 2007.

The Bank is incorporated and domiciled in Australia. It is a company limited by shares that are publicly traded on the Australian Stock Exchange. The address of its registered office is Level 7, 48 Martin Place, Sydney NSW 1155, Australia.

The Group is one of Australia’s leading providers of integrated financial services including retail, business and institutional banking, superannuation, life insurance, general insurance, funds management, broking services and finance company activities. The principal activities of the Commonwealth Bank Group during the financial period were:

(i) Banking

The Group provides retail banking services including housing loans, credit cards, personal loans, savings and cheque accounts, and demand and term deposits. The Group also offers commercial products including business loans, equipment and trade finance, and rural and agribusiness products. The Group also has full service banking operations in New Zealand, Fiji and Indonesia. The Group has wholesale banking operations in London, New York, Hong Kong, Singapore, Indonesia, regions of China, Tokyo and Malta.

(ii) Funds Management

The Group’s funds management business comprises wholesale and retail investment, superannuation and retirement funds. Investments are across all major asset classes including Australian and international shares, property, fixed interest and cash. The Group also has funds management businesses in New Zealand, the United Kingdom and Asia.

(iii) Insurance

The Group provides term insurance, disability insurance, annuities, master trusts, investment products and household general insurance. Life insurance operations are also conducted in New Zealand, where the Group has the leading market share, and in Asia and the Pacific.

There have been no significant changes in the nature of the principal activities of the Group during the half year.

(a) Bases of accounting

This general purpose financial report for the interim half year reporting period ended 31 December 2006 has been prepared in accordance with the requirements of the Corporations Act 2001 and AASB 134 Interim Financial Reporting.

This half year financial report complies with current Australian Accounting Standards which consist of Australian equivalents to International Financial Reporting Standards (AIFRS).

This half year financial report does not include all notes of the type normally included within the Annual Financial Report and therefore, cannot be expected to provide as full an understanding of the financial position and financial performance of the Group as that given by the Annual Financial Report.

As a result, this report should be read in conjunction with the 30 June 2006 Annual Financial Report of the Group included in the Bank’s Annual Report on Form 20-F for the fiscal year ended 30 June 2006 and any public announcements made in the period by the Group in accordance with the continuous disclosure requirements of the Corporations Act 2001 and the ASX Listing Rules.

For the purpose of this half year Financial Report, the half year has been treated as a discrete reporting period.

(b) Basis of preparation

The accounting policies followed in this half year Financial Report are the same as those applied in the Bank’s Annual Report on Form 20-F for the fiscal year ended 30 June 2006.

(1)

The December 2006 half includes an accounting loss of $66 million ($46 million after tax) due to the unwind of a structured financing transaction at the request of the counterparty. The transaction had been fully economically hedged at inception in 2003, and on transition to AIFRS on 1 July 2005 the hedge profit was recognised in retained profits. Interest expense offsetting the hedge was being amortised over the life of the transaction. The unwind of the transaction brings forward the recognition of this expense to the current period. There is no overall economic loss incurred by the Group. The Group is not aware of any other contracts of a similar nature.

(2)

The December 2005 half includes profit on sale of the Hong Kong Insurance Business of $145 million.

(1) Changes to the market conditions of the Equity Reward Plan were approved by the Group’s Remuneration Committee in November 2006. This modification has changed the definition of the comparator group against which the Bank’s Total Shareholder Return is compared. In relation to the 2002 and 2003 plans, this modification has resulted in additional vesting of $36 million in the half year to 31 December 2006.

New Zealand Subsidiaries

Assessments have been received from the IRD in respect of one structured finance investment in relation to the year ended 30 June 2001. Notices of proposed adjustment have been received for other similar investments for other years.

The Bank is confident that the tax treatment it has adopted for these investments is correct, and any assessments received will be disputed.

(1) While the Group is required to maintain a Prudential General Reserve for Credit Losses (“GRCL”) to cover credit losses estimated over the life of portfolio facilities, from 1 July 2006 the Australian prudential regulator, APRA, no longer requires banks to maintain a minimum provisioning benchmark of 0.5% (after tax) of risk weighted assets. The Group’s GRCL within shareholders’ equity, which is over and above APRA requirements, has been retained as part of the Prudential General Reserve for Credit Losses for prudential reporting purposes (refer to Capital Adequacy, Appendix 8, pages 79-81).

Provisioning Policy

Provisions for impairment are maintained at an amount adequate to cover incurred credit losses.

The Group first assesses whether objective evidence of impairment exists individually for financial assets that are individually significant and individually or collectively for financial assets that are not individually significant. If there is objective evidence of impairment, the amount of the loss is measured as the difference between the asset’s carrying amount and the present value of the expected future cash flows discounted at the financial asset’s original effective interest rate. Short term balances are not discounted.

For prudential reporting purposes the collective provision ($1,040 million), other credit provisions ($19 million), fair value credit adjustments ($31 million) and General Reserve for Credit Losses (pre-tax equivalent $500 million), a total of $1,590 million, equates to 0.68% of risk weighted assets.

Notes to the Financial Statements

Note 11 Assets Held for Sale

During the half year ended 31 December 2006 the Group purchased through Colonial First State a 32% stake in AWG plc. The stake was acquired through the purchase of preference shares and eurobonds that have been classified as Assets Held for Sale ($1.3 billion), as the Group intends to dispose of its holding into Australian and European based infrastructure funds within the next 12 months.

Until sold, the holding will be measured at the lower of carrying amount and fair value less costs to sell. Interest revenue on the eurobonds will be accrued, while dividend revenue on the preference shares will be recognised when declared.

Note 12 Events after the end of the Financial Period

Dividends

The Directors have declared a fully franked dividend of 107 cents per share — amounting to $1,380 million for the half year ended 31 December 2006. On 13 February 2007 the appointment of Mr Harrison Young as a Director of the Bank was announced. Mr Young’s appointment was effective immediately.

The Directors are not aware of any other matter or circumstance that has occurred since the end of the half year that has significantly affected or may significantly affect the operations of the Bank, the results of those operations, or the state of affairs of the Bank in subsequent financial years.

Note 13 Contingent Liabilities

There have been no material changes in contingent liabilities since those disclosed in the Financial Statements for the year ended 30 June 2006. Refer to Note 42 in the Bank’s Annual Report on Form 20-F for the fiscal year ended 30 June 2006.

56   Commonwealth Bank of Australia Profit Announcement (U.S. version — with U.S. GAAP reconciliation)

Notes to the Financial Statements

Note 18 Differences between Australian and United States Accounting Principles (continued)

(a) Income Tax

Policyholder Liabilities

From 1 July 2000, the basis for taxation of income on most life insurance products changed from ‘Income minus Expenditure’ to ‘Profit’ (which includes movements in policyholder liabilities). As tax deductible policyholder liabilities under Australian tax legislation are lower than US GAAP policyholder liabilities, a deferred tax asset to recognise this timing difference is created. The adjustment to US GAAP for the half year ended 31 December 2006 is $51 million (2005: $49 million).

Available-for-sale Investments

Income from tax exempt securities does not exceed $500,000.

Foreign Currency Translation Reserve (FCTR)

For US GAAP purposes, the tax effect of the pre 1 July 2004 FCTR is recognised as a deferred tax asset. For half year ended 31 December 2006, this represented a $26 million increase to Shareholders’ Equity (2005: $26 million).

(b) Employee Share Based Compensation

The AIFRS accounting for the Group’s employee share plans is detailed in Note 33 of the Bank’s Annual Report on Form 20-F for the fiscal year ended 30 June 2006. The AIFRS accounting for share based compensation expense is generally consistent with US GAAP.

The only area of significant difference between AIFRS and US GAAP relates to the Balance Sheet treatment of Treasury Shares held within an Employee Share Trust that holds shares in the Bank on behalf of employees. This Trust is consolidated for AIFRS, but is deconsolidated for US GAAP due to its classification as an Employee Share Option Plan (“ESOP”). This results in the reinstatement of the cost of the shares to ordinary share capital for US GAAP for the half year ended 31 December 2006 of $47 million (2005: $134 million). This results in the recognition of a prepaid share-based compensation asset.

(c) Provisions

Under AIFRS, provisions for redundancies are recognised when a reliable estimate can be made of a present obligation which exists as the result of a past event.

The criteria for recognition of provisions for redundancies are currently more strict under US GAAP than AIFRS. SFAS 146 Accounting for Costs Associated with Exit or Disposal Activities only allows recognition of a provision for redundancies where the redundancies are made within the minimum legal notification period, from the balance date, on a pro-rata basis over the future service period of terminating employees.

During the half year ended 31 December 2006, $ nil was reversed from expense (2005: $11 Million) and $37 million was reduced from provisions for US GAAP purposes (2005: $85 million).

The accounting policy adopted by the Group for restructuring provisions is detailed in Note 1 (aa) of the Bank’s Annual Report on Form 20-F for the fiscal year ended 30 June 2006.

(d) Life Insurance Controlled Entities

Under AIFRS, assets and liabilities of life insurance controlled entities are classified as assets at fair value through Income Statement and are measured at fair value.

For US GAAP, predominantly all debt and equity security assets of life insurance controlled entities have been categorised as Trading Assets and brought to account through Net Income at market values.

(e) Assets at Fair Value through Income Statement

Under IFRS — specifically AASB 139 (effective 1 July 2005) — an option exists to classify certain non-trading assets as “assets at fair value through Income Statement” and measure these assets accordingly. This is known as the “fair value option”. No such option currently exists under US GAAP. As such, these assets have been reclassified as ‘Available for sale investments’, ‘Loans, advances and other receivables’ and ‘Other Assets’ for US GAAP purposes.

For unquoted equity securities classified as ‘Available for sale investments’ under AIFRS the difference between the carrying value and market value has been reversed, and the assets have been reclassified to other assets, for US GAAP purposes. For the half year ended 31 December 2006 the adjustment decreased Other Comprehensive Income and Shareholders’ Equity by $31 million (2005: $40 million).

Under AIFRS the unrealised gains and losses on available-for-sale investments are classified as part of Shareholders’ Equity. Under US GAAP these amounts are disclosed within Other Comprehensive Income.

For assets classified as Loans, advances and other receivables, unrealised losses of $8 million were reversed from the Income Statement (2005: $1 million).

Liabilities at Fair Value through Income Statement.

Under IFRS — specifically AASB 139 (effective 1 July 2005) — an option exists to classify certain non-trading assets as “liabilities at fair value through Income Statement” and measure these liabilities accordingly. This is known as the “fair value option”. No such option currently exists under US GAAP. As such, these liabilities have been reclassified as ‘Deposits and Other public borrowings’, ‘Payables due to Other financial institutions’ and ‘Debt Issues’ and ‘Bills Payables and Other Liabilities’ for US GAAP purposes.

For the half year ended 31 December 2006, the reversal of the mark to market movement on these liabilities resulted in an increase to Shareholders’ Equity of $2 million (2005: decrease of $11 million).

(f) Details of Pension Expense and Reconciliation of Funded Status of Pension Plans

The Group sponsors a range of superannuation (pension) plans for its employees world-wide.

The Group’s accounting policy for superannuation expense, under AIFRS reporting, is set out in Note 1 of the Financial Statements of the Bank’s Annual Report on Form 20-F for the fiscal year ended 30 June 2006. The disclosure of the Bank’s major superannuation plans are set out in Note 44 to the financial statements in the Bank’s Annual Report on Form 20-F for the fiscal year ended 30 June 2006. All amounts are expressed in Australian Dollars.

Under AIFRS, the surpluses and/or deficits that arise within individual defined benefit superannuation plans must be recognised in the Balance Sheet. There is a choice of three options for the recognition of actuarial gains and losses related to defined benefit superannuation plans within Profit or Retained Earnings. The options include direct recognition in Profit of all of the actuarial gain or loss, direct recognition in Retained Earnings of all of the actuarial gain or loss, or the ‘corridor’ approach which progressively recognises a certain portion of the gain or loss within Profit over the expected average remaining working lives of employees within the plan. The Bank has selected direct recognition in Retained Earnings as the method of accounting for the defined benefit superannuation plans.

For US GAAP purposes, the Bank adopted the disclosure requirements of SFAS 87 “Employers’ Accounting for Pensions” for the major defined benefit fund, the Officers’ Superannuation Fund (OSF), commencing 1 July 1994. For the Financial Year ending 30 June 1999, the Bank revised its disclosures in accordance with SFAS 132 “Employers’ Disclosures about Pensions and Other Postretirement Benefits”.

In adopting SFAS 87 “Employers’ Accounting for Pensions”, the Bank applied the ‘corridor’ approach of recognising actuarial gains or losses. Direct recognition of actuarial gains or losses in Retained Earnings is not permitted under SFAS 87, and therefore reconciliation adjustments are required.

The Group adopted SFAS 87 later than the effective date specified in the accounting standard. To introduce the information required under SFAS 87 as from the effective date was not feasible. Accordingly an allocation of the pension obligation/asset has been taken directly to equity based on the number of years elapsed between the effective date and the date of adoption by the Group. The adoption date for the purposes of the US GAAP reconciliation is 1 July 1994 and the remaining amortisation period at the adoption date was ten years.

The following table displays a reconciliation of pension expense and recognised surplus under AIFRS and US GAAP at 31 December 2006 and 31 December 2005 for the Group’s major superannuation (pension) plans.

Notes to the Financial Statements

Note 18 Differences between Australian and United States Accounting Principles (continued)

The accumulated benefit obligations for all defined benefit superannuation (pension) plans as at 30 June 2006 was $3,667 million (30 June 2005: $3,658 million).

As at 30 June 2006, the projected benefit obligations and accumulated benefit obligations of the CBA(UK)SBS exceeded the fair value of plan assets. Comparative information are as follows:

	2006		2005
	$M		$M
Projected benefit obligation		430		408
Accumulated benefit obligation		426		404
Fair value of plan assets		366		326

The assumptions used to calculate the above and the details of the Bank’s funding policy and contributions in respect of its major superannuation (pension) plans are set out in Note 44 of the Bank’s Annual Report on Form 20-F for the fiscal year ended 30 June 2006.

The expected future benefit payments of the Bank’s major superannuation (pension) plans are as follows:

Financial Year Ending	$M
30 June 2007 232
30 June 2008		232
30 June 2009		233
30 June 2010		240
30 June 2011		239
30 June 2012 to 30 June 2016		1,201

The above expected benefit payments are calculated by the respective fund actuaries using assumptions of future total service, the rate of exits from the fund and future salary growth. Actual benefit payments will depend on actual service period, actual rate of exits from the fund and actual salary growth.

The Group provides insurance cover to OSF in respect of its death, total and permanent disablement and temporary disablement benefits. As at 30 June 2006, the amounts of cover were $5,274 million of lump sum death and total and permanent disablement benefits (2005: $5,036 million) and $52 million per annum of temporary disablement benefits (2005: $61 million per annum).

(g) Intangible Assets

Colonial Limited was acquired on 13 June 2000 (refer to Notes 21 and 51(w) of the Bank’s Annual Report on Form 20-F for the fiscal year ended 30 June 2006 for further details). Differences exist between the method of calculation of the cost of acquisition under previous AGAAP and US GAAP. Refer to Note 18(t) for further details. Under AIFRS goodwill on acquisition was determined as the difference between the cost of acquisition and the fair value of net assets acquired. This results in permanent adjustments within Shareholders’ Equity related to various elements of the Colonial acquisition.

US GAAP identifiable intangible assets acquired include Value of Business Acquired ($1,509 million), and the Colonial State Bank Core Deposits ($149 million). The Core Deposits are being amortised on a straight line basis over 8 years (annual amortisation expense of $19 million).

Under US GAAP goodwill on acquisition is determined as the difference between the cost of acquisition and the fair value of net tangible and intangible assets acquired. Goodwill amortisation ceased, under AIFRS from 1 July 2004. Goodwill amortisation for US GAAP ceased from 1 July 2002. Under both US GAAP and AIFRS, the carrying value of goodwill is subject to review for impairment each period end. US GAAP goodwill also includes a $332 million amount relating to the recognition of life insurance synergy benefits.

The Group’s carrying amount of goodwill under US GAAP at 31 December 2006 is disclosed for each reportable segment as follows:

	31/12/06		31/12/05
Segment	$M		$M
Banking		4,182		4,190
Funds Management		977		998

Note 18 Differences between Australian and United States Accounting Principles (continued)

(h) Value of Business Acquired (‘VOBA’)

Under AIFRS for non-life insurance holding companies, the difference between the purchase price on acquisition and the net assets plus identifiable intangible assets acquired represents goodwill. No separately identified intangible asset is recognised for the Value of Business Acquired (‘VOBA’).

For US GAAP, prior to the assignment of the excess of purchase price over net assets acquired to goodwill, the identifiable intangible asset VOBA is recognised. VOBA represents the estimated fair value of the acquired life insurance business in force and represents the portion of acquisition cost that was allocated to the value of future cash flows from insurance contracts existing at the date of acquisition. Such value is the present value of the actuarially determined projected net cash flows from the acquired insurance contracts.

VOBA is amortised over the lives of the acquired business in force in a manner consistent with amortisation of deferred policy costs for life insurance contracts and in a manner expected for funds management contracts (see Note 18 (m)). An analysis of the Colonial VOBA asset (net of tax) is presented below:

	31/12/06			31/12/05
	$M			$M
Opening balance, 1 July		614			777
Imputed interest		84			124
Amortisation		(119	)		(166	)
Disposal of Hong Kong Insurance Business		—			(81	)
Movement in deferred tax liability on value of business acquired		5			1
Closing Net Balance, 31 December		584			655

The net movement in VOBA excluding the impact of the sale of the Hong Kong Insurance Business for the half year end 31 December 2006 is $35 million (2005: $42 million). For all Australian life insurance business the imputed rates of interest are related to the underlying investment earnings rate and range from 2.2% to 8.6% dependent upon the nature of the business. Given that imputed interest rates are dependent upon actual investment performance they are expected to be volatile. The imputed interest rates for all other business range from 6.1% to 8.4%.

The amortisation rate for the investment-linked life business also depends upon actual investment performance and is therefore also expected to be volatile. The VOBA balance is estimated to be run-off at a rate ranging from 2.8% to 15.0% per year.

Recoverability Test

Under US GAAP the amount of VOBA written-off in the period was determined by comparing the carrying value of VOBA at 31 December 2006 after allowing for imputed interest and amortisation, to an end of period recoverable amount valuation.

(i) Property and Other Non-Current Asset Revaluations

Each year a review is performed to assess the recoverable amount of non current assets. The ‘recoverable amount test’ is in accordance with the AIFRS standard which requires future cash flows associated with non-current assets to be discounted at a rate which reflects the risk involved. Under AIFRS, and the requirements of SFAS 144: Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of, the determination of the fair value of non-current assets and the recognition of losses from impairments, requirements, are essentially the same.

AIFRS allows non-current assets including property, plant and equipment to be revalued upwards to their recoverable amount with the gain recognised in an asset revaluation reserve. Impairments to asset values, where there is an amount in the revaluation reserve relating to the relevant assets, are taken to reduce the revaluation reserve. Impairments to asset values are otherwise recognised in Net Income. Any subsequent upward reversing revaluations of the same asset are recorded in Net Income. With the exception of land, all revalued assets are depreciated over their assessed useful lives.

Under US GAAP upward revaluations of property, plant and equipment are not allowed, except as part of accounting for business combinations under the Purchase Method. US GAAP requires all impairments of non current assets to be recorded in Net Income. Once such impairments have been recorded, subsequent recoveries to the income statement are not allowed.

A discounted cash flow methodology was used in determining the Group’s property valuations. At 31 December 2006, the Asset Revaluation Reserve balance was $130 million (2005: $117 million). Under US GAAP this was reversed for the half year ends 31 December 2005 and 2006. No adjustment has been made for the decrease in depreciation due to the reversal of Asset Revaluation Reserve as it is not material in the Income Statement.

(j) Properties Held by Insurance Companies

Under AIFRS, properties held by insurance companies are held in the Balance Sheet at net market value, which is market value less expected cost of disposal. Investment properties are valued annually by an independent valuer with changes in value taken directly to investment income in Net Income. No depreciation is charged on investment properties. The insurance companies do not hold property other than as an investment.

Under US GAAP, such property is recorded at historical cost in the Balance Sheet and depreciated over its useful life — except for land which is not depreciated.

For the half year end 31 December 2006, the restatement under US GAAP results is $27 million increase in Net Income (2005: decrease of $36 million), and $139 million (2005: $160 million) pre-tax reduction in Shareholders’ Equity.

Note 18 Differences between Australian and United States Accounting Principles (continued)

(l) Life Insurance

AIFRS requires the Group’s life insurance business to be classified as either life insurance contracts, where insurance risk exists, or life investment contracts for all other life insurance business. Investment contracts consist of a financial instrument and an investment management services element, both of which are measured at fair value. The resulting liability to policyholders is linked to the performance and the value of the assets (after tax) that back those liabilities.

Life insurance contracts use the Margin on Services (“MoS”) methodology to calculate policy liabilities. Under MoS, policy liabilities are based on best estimate assumptions which are reviewed at each valuation date. Policy liabilities are made up of two components, the Best Estimate Liabilities and Future Profit Margins.

Best Estimate Liabilities represent the present value of future payments to policyholders and related expenses less the present value of future gross premiums.

Future Profit Margins represent the present value of estimated profits. The profit margins are determined from outset of the contract and updated with changes in best estimate assumptions. The profit margins are expressed as a percentage of “profit carriers”, where profit carriers are indicative of the underlying nature of the services provided to policyholders. Profit margins are recognised in earnings based on the profit margin percentage and the amount of the specific profit carrier (e.g. claims paid, premiums, policy charges etc.)

If, during the process of valuing the policy liabilities, it is found that future profits are negative (i.e. the policy is in a loss position), then:

(i) the profit margin is set to zero; and

(ii) all future losses are recognised immediately.

If expectations change in the future, it is possible to reverse capitalised losses and re-establish profit margins. This is explained in more detail in Note 1 (hh) to the financial statements in the Bank’s Annual Report on Form 20-F for the fiscal year ended 30 June 2006.

US GAAP applies two standards (a third, SFAS 120, is not relevant) to policies written by the Group’s life insurance companies:

(i) SFAS 60: Accounting and Reporting by Insurance Enterprises applies to products such as traditional whole of life, certain endowment contracts, life contingent annuity contracts, term insurance, disability income protection and group life.

Under SFAS 60, policy liabilities, which represent the present value of future benefits to be paid to or on behalf of policy owners and related expenses less the present value of future net premiums, shall be estimated using methods that include assumptions, such as estimates of expected investment yields, mortality, morbidity, terminations and expenses, applicable at the time the insurance contracts are made.

These assumptions are ‘locked-in’ at inception for all future valuations — except in specific circumstances such as loss recognition.

The assumptions used for SFAS 60 are based on a best estimate of expected long-term experience together with provisions for adverse deviation (‘PADs’).

The policyholder liability and the amount of deferred acquisition costs are regularly tested using best estimate assumptions to assess recoverability which could result in the writedown of deferred acquisition costs or an increase in the policyholder liabilities.

(ii) SFAS 97: Accounting and Reporting by Insurance Enterprises for Certain Long-Duration Contracts and for Realised Gains and Losses from the Sale of Investments covers investment contracts and universal life policies, such as unit-linked and investment account policies.

Under SFAS 97, the liability is set equal to:

• the account balance that accrues to the benefit of the policyholder at the date of the Financial Statements; and

• any unearned revenue liability;

Assumptions are generally updated at each valuation and do not include any PADs.

The Group operates investment-linked business which was classified as separate account business for Financial Years up to and including 2004. Such accounts represent assets and liabilities that are maintained by the Group for purposes of funding superannuation (pension) funds and other investment type activities. The accounts represent policyholder directed funds that are separately administered. The assets and the liabilities of each account are clearly identifiable and distinguishable from other assets and liabilities of the Group. The policyholder generally assumes the investment risk and investment income accrues directly to the policyholders and, therefore, are not included in the Group’s Income Statement. The Group receives fees for investment management, certain administrative expenses, and mortality and expense risks assumed, which are recognised when due.

Prior to 1 July 2004, investments in separate accounts supporting unit linked contracts were reported at market value and reclassified from insurance investment assets to other assets under US GAAP. Separate account liabilities represent the policyholder’s claim to the related assets and are carried at the policyholder’s account balance. Insurance investment assets and policyholder liabilities are reported as summary totals in the Balance Sheet. Such totals are disclosed in Notes 10 and 38 of the Bank’s Annual Report on Form 20-F for the fiscal year ended 30 June 2006.

From 1 July 2004, the investment-linked business did not meet the revised criteria for separate account treatment, as outlined in SOP 03-1. Accordingly, there is no longer any reclassification of separate account business, and mortgage loans have been remeasured from market value to amortised cost and reclassified as other assets.

For the half year ended 31 December 2006 the US GAAP adjustment is a decrease of $1 million in Net Income (2005: increase of $14 million).

Note 18 Differences between Australian and United States Accounting Principles (continued)

(m) Deferred Acquisition Costs (‘DAC’) — Expenses of Acquiring Life Insurance, Investment and Related Contracts

Under AIFRS, only acquisition costs are deferrable on investment contracts, whereas both fixed and variable costs incurred in acquiring the business are deferrable on insurance contracts. This includes commissions and the costs of accepting, issuing and initially recording policies. Under AIFRS, acquisition costs on investment contracts are explicitly held as assets on the Balance Sheet. Acquisition costs on insurance contracts are implicitly held as part of the policy liability and movements are recognised as reductions in the AIFRS policyholder liabilities. Movements in DAC assets on insurance contracts are not reported separately in the Income Statement; rather, they are reported as a component of the movement in policyholder liabilities under AIFRS.

The definition of acquisition costs is wider under AIFRS for insurance contracts and narrower for investment contracts than under US GAAP. Under US GAAP only those costs that vary with, and are primarily related to, the production of new and renewal business (acquisition costs), are capitalised.

Under US GAAP, these DAC assets are amortised to expense in proportion to different measures, depending on the type of policy.

For policies accounted for under SFAS 60, these costs are amortised in proportion to premium revenue recognised. Amortisation assumptions relating to DAC assets for SFAS 60 policyholder liabilities, are ‘locked-in’ for all future valuations — except in specific circumstances such as loss recognition.

For policies accounted for under SFAS 97 these costs are amortised at a rate based on the present value of estimated gross profits expected to be realised over the life of the contracts. The DAC asset and related amortisation is updated at every reporting date, based upon the gross profits recognised and expectations of future gross profits. DAC assets are written off to the extent it is determined that future income is insufficient to cover future expenses (including the amortisation of the existing DAC).

Under US GAAP, amortisation of the DAC assets is reported separately from changes in policyholder liabilities in the Income Statement.

Under US GAAP, DAC is reported as an asset in the Balance Sheet rather than offset against policyholder liabilities. However, no DAC was recorded upon the initial purchase of Colonial Limited.

The net adjustment of DAC to Net Income for US GAAP is comprised of:

	31/12/06			31/12/05
	$M			$M
Difference in deferral of new business acquisition expenses		(34	)		(27	)
Difference in amortisation of acquisition expenses		40			30

Notes to the Financial Statements

(n) Securitisation of Assets

During the half year ends 2005 and 2006, the Group securitised mortgage loans to Special Purpose Entities (SPEs). Under AIFRS these entities are consolidated. Under US GAAP the conditions to derecognise securitised loans include the provision that the transferor does not retain effective control over, or more than a trivial interest in, the transferred assets.

The Group meets the requirements of US GAAP not to consolidate the SPEs. Note 1 (ii) of the Bank’s Annual Report on Form 20-F for the fiscal year ended 30 June 2006, Asset Securitisation, outlines the accounting treatment under AIFRS. Under US GAAP reporting as required by SFAS 140, the SPEs used by the Bank for Asset Securitisation have been deemed Qualifying Special Purpose Entities (“QSPEs”). As a result the SPEs used by the Bank for Asset Securitisation that qualify as QSPEs as at 31 December 2006 have been deconsolidated resulting in assets decreasing by $10,584 million net of $158 million of retained income units (2005: $9,547 million).

The Bank has retained a portion of income from loans securitised during the period through the holding of income units in deconsolidated SPEs. The Bank carries these retained interests at fair value based on the discounted cash flows expected to be received. The retained interests are treated as available-for-sale securities.

The key assumptions used in measuring the fair value of retained interests at the time of securitisation are as follows:

		��
	31/12/06
Discount rate		6.25	%
Payment rate(1)		28	%
Expected weighted average life	6 yrs

(1) Cumulative Prepayment Rate (‘CPR’) which represents an estimate of the principal repaid on an annual basis.

The outstanding balance of securitised loans at 31 December 2006 was $10,596 million net of $158 million of retained income units (2005: $9,124 million). No credit losses were incurred by the Group in relation to these securitised loans during the half year ends 2005 and 2006. The credit risk in respect of these loans is fully covered through mortgage insurance.

Cashflows paid to the Group from the QSPEs were:

	31/12/06		31/12/05
	$M		$M
Servicing fee		14		9
Management fee		2		2
Excess servicing fee		24		19

(o) Derivative Instruments and Hedging Activities

SFAS 133: Accounting for Derivative Instruments and Hedging Activities was issued in June 1998 and subsequently amended by SFAS 138 and SFAS 149. The statements require all derivatives to be recorded on the Balance Sheet at their fair value. The treatment of the change in the fair value of derivatives is recorded in Net Income or Other Comprehensive Income depending on the classification of the derivative transaction. Note 43, Market Risk, of the Bank’s Annual Report in From 20-F for the fiscal year ended 30 June 2006 outlines the Group’s market risk policy specifying the purpose of derivative activity and the risks being hedged. Note 1 (ff), Derivative financial instruments of the Bank’s Annual Report on Form 20-F for the fiscal year ended 30 June 2006, outlines the accounting recognition of derivatives under AIFRS, with disclosure set out in Note 11, Derivative Assets and Liabilities, of the Bank’s Annual Report on Form 20-F for the fiscal year ended 30 June 2006.

Under US GAAP, derivative hedges of financial instruments of the Group, that are highly effective, qualify for hedge accounting and have been classified as fair value hedges or cash flow hedges.

For fair value hedges, the change in the fair value of the derivative hedge offsets the change in the fair value of the financial instrument being hedged. Under US GAAP the gain or loss on the derivative and the offsetting loss or gain in the fair value of the financial instrument being hedged, are recognised immediately in Net Income in the same accounting period. The change in fair value of the derivative hedge is recognised as an asset or liability on the Balance Sheet. The change in the fair value of the financial instrument being hedged is recognised as part of the carrying value of the financial instrument. The risk characteristics of the financial instrument being hedged are mirrored under the hedge, and effectiveness is evaluated on a retrospective and prospective basis. The ineffective portions of fair value hedges for US GAAP purposes are included in the reconciling item in this Note — adjustment to derivative and hedge accounting.

Certain of the Group’s financial instruments designated as hedged items in a fair value hedge under AIFRS do not meet the required specific hedge criteria set out in SFAS 133 and therefore have not been measured at their fair value for US GAAP purposes.

All cash flow hedges designated under AIFRS are reversed and replaced where applicable with hedging relationships separately designated under SFAS 133. A valuation gain or loss associated with the effective portion of a derivative designated as a cash flow hedge is recognised initially in Other Comprehensive Income within the cash flow hedge reserve. Amounts from the cash flow hedge reserve are transferred to Net Income when the cash flows on the hedged item are recognised in Net Income. Gains and losses resulting from cash flow hedge ineffectiveness are recorded in Net Income.

This represents the amount by which changes in the cash flows of the hedging derivative differ from changes (or expected changes) in the cash flow of the hedged item.

If for reasons other than the derecognition of the hedged item, cash flow hedge accounting ceases, the cumulative gains or losses are amortised to Net Income over the remaining term of the original hedge. Where the hedged item is derecognised, the cumulative gain or loss is recognised immediately in Net Income.

All other derivatives of the Group are held for trading purposes and are recorded at fair value with changes in fair value recognised immediately in Net Income.

SFAS 133, 138 and 149 have been fully applied for the relevant half year ends. Application of these statements increased US GAAP Net Income by $1,053 million (2005: decreased by $983 million), primarily due to a decrease in US interest rates during the period and decreased Other Comprehensive Income by $102 million (2005: $50 million). Balance Sheet derivative assets and underlying assets and derivative and other liabilities increased by $58 million (2005: decreased by $6 million) and increased by $968 million (2005: $759 million) respectively.

(p) Collateral on Transfer of Assets

The Group conducts collateral arrangements with counterparties covering a range of specified transactions. Collateral arrangements are activated upon predetermined thresholds being exceeded. A range of specified assets may be received or provided as collateral.

As at 31 December 2006 securities with fair value of $4,580 million were received as collateral (2005: $3,708 million). In addition, securities to the value of $3,856 million were provided as collateral as at 31 December 2006 (2005: $2,744 million).

(q) Credit Risk Related Instruments

The Group is involved in a range of transactions that give rise to contingent and/or future liabilities. These have been disclosed in Note 42 of the Bank’s Annual Report on Form 20-F for the fiscal year ended 30 June 2006 as Off-Balance Sheet items. US GAAP, FIN 45, Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Guarantees of Indebtedness of Others, effective 1 January 2003, requires that the fair value of these liabilities be recognised in the Financial Statements. This is consistent with AIFRS, which also requires recognition of the fair value of these liabilities.

(r) Variable Interest Entities

The Group has applied Financial Accounting Standards Board (“FASB”) Interpretation No. 46, Consolidation of Variable Interest Entities (revised December 2003), (“FIN46-R”) from 1 July 2004 to all Variable Interest Entities. FIN 46-R created the Variable Interest Entity (“VIE”) concept and defines a VIE to include an entity which has insufficient equity at risk to finance its activities without additional subordinated financial support from other parties. In addition the VIE concept includes entities which have voting rights disproportionate to their economic interests and where the activities of the entity are conducted on behalf of investors with disproportionately small or no voting rights. Where an entity is a VIE, the FIN 46-R consolidation model must be applied. Under US GAAP, a VIE is consolidated where the Group is deemed to be the primary beneficiary, i.e. when it is expected to absorb a majority of the VIE’s expected losses, expected residual returns, or both. When the Group is not the primary beneficiary the VIE is deconsolidated. The Group has a number of Qualifying Special Purpose Entities which are excluded from the scope of FIN 46-R and have been addressed in Note 18 (n).

As a result of the application of FIN 46-R, as at 31 December 2006, the deconsolidation of 5 VIEs resulted in assets decreasing by $1 million (2005: nil), and Shareholders’ Equity decreasing by $1 million (2005: nil), with a decrease in income of $1 million (2005: nil).

Entities which are Deconsolidated for US GAAP purposes

In certain cases, an entity consolidated under AIFRS is not consolidated under FIN 46-R. Under AIFRS, the Group consolidates several entities that have issued preferred securities which are deconsolidated for US GAAP purposes. This results in different instruments being deemed external to the Group when assessing the Group’s capital raising structures.

Significant Capital Raisings impacted under US GAAP

PERLS II

On 6 January 2004 a wholly owned entity of the Bank (Commonwealth Managed Investments Limited, as Responsible Entity of the PERLS II Trust) issued $750 million of Perpetual Exchangeable Resettable Listed Securities (“PERLS II”). These securities are units in a registered managed investments scheme, perpetual in nature, offering a non-cumulative floating rate distribution payable quarterly. The Securities qualify as Tier One capital of the Bank.

The PERLS II Trust is a VIE under FIN 46-R, however the Group is not considered to be the Primary Beneficiary under FIN 46-R. As a result the trust has been deconsolidated for US GAAP purposes.

The assets of the trust are Convertible Notes issued by the New Zealand branch of the Commonwealth Bank. The Convertible Notes have been classified as loan capital of the Group.

Trust Preferred Securities (2003)

On 6 August 2003 a wholly owned entity of the Bank issued USD$550 million (AUD$832 million) of perpetual non-call 12 year trust preferred securities into the US capital markets. These securities offer a non-cumulative fixed rate distribution of 5.805% per annum payable semi-annually. The Group issued these Trust Preferred Securities out of special purpose entities that are deemed to be VIEs. However, the Group is not considered to be the Primary Beneficiary of the VIEs. The external funding instruments under US GAAP are mandatorily convertible notes that continue to be classified as loan capital.

PERLS III

On 7 April 2006, a wholly owned entity of the Bank (Preferred Capital Limited) issued $1,166 million of Perpetual Exchangeable Repurchaseable Listed Shares (PERLS III). Preferred Capital Limited is a VIE, however the Group is not considered to be the Primary Beneficiary. The external funding instruments under US GAAP are convertible notes issued by the New Zealand Branch of Commonwealth Bank. The convertible notes have been classified as loan capital of the Group.

Trust Preferred Securities (2006)

On 15 March 2006, the Bank issued USD700 million (AUD947 million) of perpetual non-call 10 year trust preferred securities into the US capital markets. These securities offer a non-cumulative fixed rate distribution of 6.024% per annum payable semi-annually. The Group issued these Trust Preferred Securities out of a special purpose entity that is a VIE, however the Group is not considered to be the Primary Beneficiary. The external funding instrument under US GAAP is an equity instrument that includes the same components as the AIFRS Trust Preferred Securities.

Note 18 Differences between Australian and United States Accounting Principles (continued)

(s) Software Amortisation

For AIFRS purposes, the criteria for information technology software capitalisation was amended from 1 July 2003, such that only computer software projects costing $10 million or more and which will deliver identifiable and sustainable customer value and an increase in returns in a significant line of business are being capitalised. This change was applied retrospectively and resulted in the expensing of $219 million in the Financial Year 2004 of previously capitalised software. For US GAAP purposes, this change cannot be retrospectively applied and has been reversed. The related software amortisation charge for the half year end 31 December 2006 under US GAAP is nil (2005: $40 million).

The reversal of the half year expensed software increased assets and income by $107 million (2005: $26 million). The combined impact of amortising the half year software and capitalizing the half year software is an increase in Net Income of $122 million (2005: decrease of $14 million).

(t) Colonial Acquisition

Purchase GAAP accounting has been applied in the acquisition of Colonial (13 June 2000).

(2)	Under US GAAP price calculated as weighted average closing price for the two days either side of the announcement date (10 March 2000). Non trading days were excluded from the calculation. Value of equity issued for Colonial acquisition under US GAAP accounting is reduced by $1,026 million.
(3)	Includes Colonial State Bank Core Deposits ($149 million) which is to be amortised on a straightline basis over 8 years and Value of Business Acquired (VOBA) net of associated deferred tax liability $1,530 million (refer to Note 18 (h) for amortisation details). The carrying value of the core deposits at 31 December 2006 is $28 million, net of amortisation.
(4)	Goodwill on acquisition under US GAAP includes the excess of net market value over net assets of life insurance controlled entities.

(u) Sale of the Hong Kong Insurance Business

The group completed the sale of its life insurance and financial planning business in Hong Kong on 18 October 2005. Due to differences under US GAAP in the calculation of insurance policyholder liabilities, VOBA and DAC, the US GAAP net assets of the Hong Kong Insurance Business were lower than the under AIFRS at the date of disposal. In addition, cumulative foreign currency movements recognised within the FCTR for US
GAAP reporting purposes were significantly different compared with AIFRS, due to the AIFRS transitional adjustment which reset the FCTR at 1 July 2004 to zero. On disposal of the Hong Kong Insurance Business, all FCTR assets are recycled to Net Income as part of the calculation of the gain on disposal. This resulted in a net increase in the profit on disposal of the Hong Kong Insurance Business of $49 million on a US GAAP basis.

(v) Loan Origination Costs

Under US GAAP, certain loan origination costs must be capitalised and amortised in addition to those capitalised under AIFRS. The additional costs relate to the portion of staff expenses that can be attributed to successful loan origination activities of the Group.

For the half year 31 December 2006 this resulted in an increase to Net Income of $14 million before tax (2005: $4m) and an increase to Shareholders’ Equity of $250 million before tax (2005: $233 million).

(w) Newly Issued Statements of the Financial Accounting Standards Board

FASB Statement No. 154, Accounting Changes and Error Corrections

Statement No. 154 changes the accounting for, and reporting of, a change in accounting principle, and is effective for accounting changes and corrections of errors in fiscal years beginning after December 15, 2005. The Group adopted this statement on 1 July 2006 and it has not had any material impact.

Notes to the Financial Statements

Note 18 Differences between Australian and United States Accounting Principles (continued)

FASB Statement No. 155, Accounting for Certain Hybrid Financial Instruments — an amendment of FASB Statements No. 133, Accounting for Derivative Financial Instruments and Hedging Activities, and No. 140, Accounting for Transfers and Servicing of Financial Assets and Extinguishment of Liabilities

Statement No. 155 will amend Statements No. 133 and 140 to allow an entity to remeasure at fair value a hybrid financial instrument that contains an embedded derivative that otherwise would require bifurcation from the host instrument, if the holder irrevocably elects to account for the entire instrument on a fair value basis. Subsequent changes in fair value would be recognised in earnings. This statement is effective for financial instruments acquired or issued after the beginning of an entity’s first fiscal year that begins after September 15, 2006, with earlier adoption permitted in certain circumstances. The Group will adopt this statement on 1 July 2007. The Group has not yet evaluated the extent to which this fair value election is likely to be made in the future.

FASB Statement No. 156, Accounting for Servicing of Financial Assets — an amendment of FASB Statement No. 140, Accounting for Transfers and Servicing of Financial Assets and Extinguishment of Liabilities

Statement No. 156 amends Statement No. 140 to address the recognition and measurement of separately recognised servicing assets and liabilities and to simplify efforts to obtain hedge-like (offset) accounting. This statement is effective as of the beginning of the first fiscal year that begins after September 15, 2006, with earlier adoption permitted in certain circumstances. The Group will adopt this statement on 1 July 2007, and expects its impact will not be material.

FASB Statement No. 157, Fair Value Measurements

Statement No. 157 establishes a definition of fair value, sets out a market based framework for measuring fair value, and requires additional disclosures about fair value measurements. The statement introduces a three level fair value hierarchy, based on reliability of inputs to valuation techniques used to determine fair values. The definitions of fair value, market based framework, the three level hierarchy and measurement guidance, are consistent with IFRS in all material respects, and so the statement is not expected to have any material impact. This statement requires certain new disclosures, in particular for assets and liabilities measured using valuation techniques which are significantly dependent on assumptions or estimates not corroborated by market data. The impact of the new disclosures is expected to be limited. This statement is effective for financial statements issued for fiscal years beginning after November 15, 2007. The Group will adopt this statement on 1 July 2008.

FASB Statement No. 158 Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans — an Amendment of FASB Statements No. 87, 88, 106, and 132(R)

This statement requires public companies to recognise on-balance sheet the funded status of defined-benefit postretirement plans from fiscal years ending after December 15, 2006, and requires plan assets and liabilities to be measured as of the balance sheet date from fiscal years ending after December 15, 2008.

The Group already measures plan assets and liabilities of its major defined benefit plans at the balance sheet date. It is expected that under this statement, actuarial gains/losses of its defined benefit postretirement plans previously not recognised under the “corridor” approach within its US GAAP financial statements, will be recognised within “Other Comprehensive Income”. Under AIFRS, the Group has selected direct recognition of actuarial gains/losses of defined benefit postretirement plans in Retained Earnings. Consequently it is expected that implementation of this statement will align the Group’s recognition of defined benefit post-retirement plans within its US GAAP financial statements to that recognised under AIFRS. The Group expects to adopt the recognition requirements of this statement at the earliest opportunity.

FASB Statement No. 159, The Fair Value Option for Financial Assets and Financial Liabilities (Including an amendment of FASB Statement No. 115)

This statement permits entities to choose to measure many financial instruments at fair value that are not currently required to be measured at fair value. It is similar, but not identical, to the fair value option under AIFRS — AASB 139. In a similar way to AASB 139, the fair value option under Statement No. 159 may be elected for a single item without electing it for other identical items, subject to certain exceptions. This statement also introduces certain presentation and disclosure requirements.

This statement is effective as of the beginning of an entity’s first fiscal year that begins after November 15, 2007, with earlier adoption permitted in certain circumstances. The Group expects to adopt this statement on 1 July 2008. The Group has not yet evaluated the extent to which this fair value election is likely to be made in the future.

FASB Interpretation FIN 48 Accounting for Uncertainty in Income Taxes — an interpretation of SFAS 109

FIN 48 prescribes a recognition threshold and measurement attribute for the recognition and measurement of tax positions. This interpretation is effective for fiscal years commencing after December 15, 2006. The Group has not yet evaluated the effect that the adoption of FIN 48 will have on its financial position and results.

(x) Newly issued Standards of the Australian Accounting Standards Board

AASB 7 Financial Instruments: Disclosures

This new standard is a disclosure standard and does not impact financial position or performance, as it does not change the recognition and measurement of financial instruments. The new standard will require entities to make enhanced disclosures about the significance of financial instruments for their financial position and performance, and quantitative and qualitative risk disclosures for all major categories of financial instruments in their Financial Statements. The Group will adopt the standard on 1 July 2007.

(4)	Due to a change in accounting policy regarding classification of interest expense on certain non traded derivatives (i.e. all interest expense on unhedged variable to variable cross currency swaps was reclassified from Other Banking Income to Net Interest Income), a reclassification of $29 million between Net Interest Income and Other Banking Income occurred in Financial Year 2006. There was no impact on total banking income or on profit.

The Prudential General Reserve for Credit Losses is now comprised of the collective provision for impairment losses, other credit provisions, fair value credit adjustments and a general reserve for credit losses within shareholders’ equity which is an additional amount reserved over and above APRA requirements.
(2)	From 1 July 2006 APRA allows only 45% of the asset revaluation reserve to be included in Tier Two capital.
(3)	APRA requires these Lower Tier Two note and bond issues to be included as if they were unhedged.
(4)	For regulatory capital purposes, Lower Tier Two note and bond issues are amortised by 20% of the original amount during each of the last five years to maturity.
(5)	APRA has granted transitional relief for Tier One and Two capital on adoption of AIFRS, which expires 1 January 2008.

(1) In calculating risk weighted assets in accordance with Standard and Poor’s agreed methodology, the equity investment in other companies ($0.8 billion) is required to be added to regulatory risk weighted assets as this amount is not deducted from ACE Capital. On an unrelated transaction, a similar amount was required to be deducted from regulatory risk weighted assets due to Standard and Poor’s different treatment of set-off arrangements where they are recognised from a legal and accounting perspective.

Active Capital Management

The Banking Group maintains a strong capital position. The Total Capital Ratio increased from 9.66% at 30 June 2006 to 9.78% at 31 December 2006. The Tier One Capital Ratio decreased from 7.56% to 7.06% during the half year to 31 December 2006 reflecting the acquisition of a major infrastructure asset in the United Kingdom and growth in Risk Weighted Assets. Risk Weighted Assets, increased to $235 billion at 31 December 2006 due to strong growth in lending assets particularly in the business/corporate sector. The Group’s credit ratings remained unchanged.

Adoption of AIFRS and Transitional Relief

The Group adopted the Australian equivalents to International Financial Reporting Standards (“AIFRS”) on 1 July 2005. However, APRA required reporting under AGAAP accounting principles to continue for regulatory capital purposes until the introduction of revised prudential standards, which took effect on 1 July 2006.

With the introduction of the revised prudential standards, APRA granted transitional relief in relation to changes to their prudential regulations from 1 July 2006 until 31 December 2007.

Total transitional relief of $1,715 million is comprised of $1,641 million relief for Tier One Capital and $74 million of relief for Upper Tier Two Capital.

Transitional relief principally relates to:

• Excess of Market Value Over Net Assets (“EMVONA”) $1,339 million;

• Software capitalised expenses $229 million; and

• Defined benefit superannuation plan deficit $45 million.

Adjusted Common Equity

The Adjusted Common Equity (“ACE”) ratio at 31 December 2006 is 4.70%, an increase from 4.39% at 1 July 2006 (on an AIFRS basis). Standard & Poor’s did not grant any transition relief for the impact of AIFRS adjustments in relation to the impact of software capitalised expenses and defined benefit superannuation plan deficit.

Significant Initiatives

The following significant initiatives were undertaken to actively manage the Group’s capital:

Tier One Capital

• Issue of $300 million shares in October 2006 to satisfy the Dividend Reinvestment Plan (“DRP”) in respect of the final dividend for 2005/06; and

• In accordance with APRA guidelines, the estimated issue of $248 million of shares to satisfy the DRP in respect of the interim dividend for 2006/07.

Tier Two Capital

• Issue of the equivalent of $1,831 million of Lower Tier Two capital; offset by

• The call and maturity of the equivalent of $206 million of Tier Two note and bond issues; and

• Decrease in the value of Tier Two note and bond issues of $180 million resulting from changes in foreign exchange movements (whilst these notes are hedged, the unhedged value is included in the calculation of regulatory capital in accordance with the APRA regulations).

Other Capital Initiatives

Issue of $700 million hybrid securities, called Funds Management Securities (“FMS”) in September 2006. The coupons on the FMS, and in some cases repayment of capital, will depend on the fees generated by the Australian Funds Management business of the Group. The issue of FMS forms part of the Group’s ongoing commitment to efficient innovative capital management.

Deductions from Total Capital

During the half year a decrease in deductions for investment in non-consolidated subsidiaries primarily reflects up-streaming of dividends from the Colonial group of companies.

Life & Fund Management Activities

As required by APRA, the Group’s investment in its life insurance and funds management companies is deducted from regulatory capital to arrive at the Banking Group’s Capital Ratios. The Group’s insurance and funds management companies held an estimated $911 million excess over regulatory capital requirements at 31 December 2006 in aggregate.

Terms and Conditions of Ordinary Share Capital

Holders of ordinary shares have the right to receive dividends as declared and in the event of winding up the Bank, to participating in the proceeds from sale of surplus assets in proportion to the number of and amounts paid up on shares held.

A shareholder has one vote on a show of hands and one vote for each fully paid share on a poll. A shareholder may be present at a general meeting in person or by proxy or attorney, and if a body corporate, it may also authorise a representative.

Dividend Franking Account

After fully franking the interim dividend to be paid for the half year ended 31 December 2006, the amount of credits available as at 31 December 2006 to frank dividends for subsequent financial years is $88 million (June 2006: nil). This figure is based on the combined franking accounts of the Bank at 31 December 2006, which have been adjusted for franking credits that will arise from the payment of income tax payable on profits for the half year ended 31 December 2006, franking debits that will arise from the payment of dividends proposed for the year and franking credits that the Bank may be prevented from distributing in subsequent financial periods. The Bank expects that future tax payments will generate sufficient franking credits for it to be able to fully frank future dividend payments. These calculations have been based on the taxation law as at 31 December 2006.

Dividends

The Directors have declared a fully franked interim dividend of 107 cents per share amounting to $1,380 million. The dividend will be payable on 5 April 2007 to shareholders on the register at 5pm on 23 February 2007. Dividends per share are based on net profit after tax (“cash basis”) per share, having regard to a range of factors including:

• Current and expected rates of business growth and the mix of business;

• Capital needs to support economic, regulatory and credit ratings requirements;

• The rate of return on assets; and

• Investments and/or divestments to support business development.

As declared in the Bank’s Annual Report on Form 20-F for the fiscal year ended 30 June 2006, a fully franked final dividend of 130 cents per share amounting to $1,668 million was paid on 5 October 2006. The payment comprised cash disbursements of $1,368 million with $300 million being reinvested by participants through the Dividend Reinvestment Plan.

Dividend Reinvestment Plan

The Bank expects to issue around $248 million of shares in respect of the Dividend Reinvestment Plan for the interim dividend for 2006/07.

Record Date

The register closed for determination of dividend entitlement and for participation in the DRP at 5:00pm on 23 February 2007 at Link Market Services Limited, Locked Bag A14, Sydney South, NSW 1235.

Ex Dividend Date

The ex-dividend date was 19 February 2007.

10. Life Insurance Business

Life Insurance contract liabilities

Appropriately qualified actuaries have been appointed in respect of each life insurance business and they have reviewed and satisfied themselves as to the accuracy of the policy liabilities included in this Financial Report, including compliance with the regulations of the Life Insurance Act “Life Act” 1995 where appropriate.

Life Investment contract liabilities

Investment contracts consist of a financial instrument and an investment management services element, both of which are measured at fair value. The financial instrument liabilities are measured in accordance with AASB 139 with changes in fair value taken to the Income Statement. Fair value represents the value of future benefit payments and fees subject to a minimum of the surrender value. The liability to policyholders is closely linked to the performance and value of the assets (net of income tax) that back those liabilities.

(1)	Includes both investment and insurance business.
(2)	Including bonuses credited to policyholders in prior years.

Taxation

Taxation has been allowed for in the determination of policy liabilities in accordance with the relevant legislation applicable in each market.

Actuarial Methods and Assumptions

Insurance contract policy liabilities have been calculated in accordance with AASB 1038 “Life Insurance Contracts” and the Margin on Services “MoS” methodology as set out in Actuarial Standard 1.04 – Valuation Standard “AS1.04” issued by the Life Insurance Actuarial Standards Board “LIASB”. The principal methods and profit carriers used for particular product groups were as follows:

Product Type	Method	Profit Carrier
Individual
Conventional	Projection	Bonuses or expected claim payments
Investment account	Projection	Bonuses or funds under management
Lump sum risk	Projection	Premiums/Expected claim payment
Income stream risk	Projection	Expected claim payments
Immediate annuities	Projection	Annuity payments
Group
Investment account	Projection	Bonuses or funds under management
Lump sum risk	Accumulation/Projection	Expected claim payments
Income stream risk	Accumulation/Projection	Expected claim payments

The ‘Projection Method’ measures the present values of estimated future policy cash flows to calculate policy liabilities. The policy cash flows incorporate investment income, premiums, expenses, redemptions and benefit payments.

Bonuses are amounts added, at the discretion of the life insurer, to the benefits currently payable under Participating Business. Bonuses may take a number of forms including reversionary bonuses, interest credits and terminal bonuses (payable on the termination of the policy).

Actuarial assumptions

Set out below is a summary of the material assumptions used in the calculation of policy liabilities.

Discount rates

Discount rates are used to discount future cash flows in the determination of policy liabilities. The discount rates assumed vary by product and are based on the risk-free rate, except for discretionary participating products where the rate is based on the expected earning rate of the assets supporting the policy liabilities, adjusted for taxation where relevant. The following table shows the applicable rates for the major classes of business in Australia and New Zealand.

Investment account – annuities (exempt from tax)		6.09		5.98

(1) For New Zealand, investment earning rates assumed were 3.9% to 5.7% net of tax.

Bonuses

The valuation assumes that the long-term supportable bonuses will be paid, which is in line with company bonus philosophy. There are no significant changes to these assumptions.

Maintenance expenses

The maintenance expenses are based on an internal analysis of experience and are assumed to increase in line with inflation each year. The expenses are expected to be sufficient to cover the cost of servicing the business in the coming year, after adjusting for one-off expenses. For Australian Participating Business, current expenses are adjusted for actual experience and assumed to increase in line with inflation each year. There are no significant changes to these assumptions.

Investment management expenses

Investment management expense assumptions vary by asset classes and are based on agreed rates with investment managers, as set out in Fund Management Arrangements. There are no significant changes to overall investment fees.

Inflation

The inflation assumption is based on current inflation levels together with consideration of future inflation rates implied by inflation-linked securities.

Benefit indexation

Benefits and premiums under most of the regular premium policies are automatically indexed. The indexation rates are based on an analysis of past experience and estimated long term inflation and vary by business and product type. There are no significant changes to these assumptions.

Taxation

The taxation basis and rates assumed vary by market and product type.

Voluntary discontinuance

Discontinuance rates are based on recent company experience and vary by market, product, age and duration inforce. There are no significant changes to these assumptions.

Surrender values

Current surrender value bases are assumed to apply in the future. There are no significant changes to these assumptions.

Mortality and morbidity

Rates vary by sex, age, product type and smoker status. Rates are based on standard mortality tables applicable to each market (e.g. IA95-97 in Australia for retail risk, IM/IF80 for annuities), adjusted for recent company experience where appropriate. There are no significant changes to these assumptions.

Solvency

Australian life insurers:

Australian life insurers are required to hold prudential reserves in excess of policy liabilities. These reserves are required to support solvency requirements and provide protection against adverse experience. Actuarial Standard AS2.04 “Solvency Standard” ‘AS2.04’ prescribes a minimum solvency requirement and the minimum level of assets required to be held in each insurance fund. All controlled Australian insurance entities complied with the solvency requirements of AS2.04.

Overseas life insurers:

Overseas insurance subsidiaries are required to hold reserves in excess of policy liabilities in accordance with local Acts and prudential rules. Each of the overseas subsidiaries complied with local requirements.

Managed assets & fiduciary activities

Arrangements are in place to ensure that asset management and other fiduciary activities of controlled entities are independent of the insurance funds and other activities of the Group.

Disaggregated information

Life Insurance business is conducted through a number of life insurance entities in Australia and overseas. Under the Australian Life Insurance Act 1995, life insurance business is conducted within one or more separate statutory funds, which are separated from the shareholders’ funds. The financial statements of Australian life insurers, which are lodged annually with the relevant Australian regulators, show all major components of the financial statements disaggregated between the various life insurance statutory funds and their shareholders’ funds, as well as between investment linked business and non-investment linked business.
