McConnell Dowell Group Annual Review 2023 3 Jurong Region Line - Contract J108, Singapore

McConnell Dowell 4 Scott Cummins - Chief Executive Officer CEO's message Increased profit performance and cash generation in this period from our Australian and NZ/Pacific businesses was overshadowed by a large loss in our SEA business. However, we enter the new financial year with our expected FY24 revenue budget secured, and a focus on project execution and improved risk management initiatives.

McConnell Dowell Group Annual Review 2023 5 Operational Performance Our overall performance in this period was mixed. While we were pleased to see excellent revenue growth across the Australian, New Zealand and Pacific Islands, and Built Environs business units, it was disappointing to see our profit impacted by underperformance of the Southeast Asian business. The result in South East Asia was primarily driven by losses on the Batangas LNG terminal project in the Philippines due to several factors including Covid-19 travel restrictions and supply chain delays with the Ukraine war. This had a material impact on the Group’s overall FY23 profit performance despite strong underlying performance across other Business Units. McConnell Dowell has resolved certain contractual claims with its client. Further, it has been agreed that McConnell Dowell will provide support services that utilise our expertise, experience, systems and capabilities to assist the client to achieve full commissioning of the project in the coming months. This has significantly reduced our financial exposure. Across the Group, several changes and new practices were established, applying further safeguards for future performance. This included the introduction of a Project Management Office at Executive level, led by experienced project management professionals and reporting directly to myself. The PMO will provide best practice support to all project management teams. We also reviewed our commercial limits policy, tightening application of commercial terms and applying a robust reconsideration of pursue/nopursue decisions at all tender review gates​. Enhanced project technical reviews designed to strengthen our assurance mechanisms, enabling us to identify specific issues earlier and allow for more timely interventions​has also been put into practice. We enter the new financial year with excellent work in hand underpinning revenue certainty, and a strong focus on delivery performance to ensure a return to profitability. Business Unit Overview Australia The Australian business unit continued to execute works across all the regions and in a range of industry sectors. Operationally, 95% of the strong project portfolio is profitable. The business unit achieved similar profitability levels as in FY22, however there are some executions and cost challenges in the current environment. Completed contracts during the year included Granite Island Causeway (SA), Ovingham Grade Separation (SA), Cranbourne Line Upgrade (Vic), Aviation Road Pedestrian Underpass (Vic), Echuca Moama Bridge (Vic). Ongoing major projects included Kidston Pumped Hydro (Qld), Western Program Alliance (Vic), Port Kembla Gas Terminal (NSW), and New Midland Station (WA). Australian government spending continued to support a strong pipeline of new project opportunities in the first half of FY23. Projects secured during this period included the award of Tasmania’s largest current civil infrastructure project – the New Bridgewater Bridge project, the Epping Road upgrade, Webb St Level Crossing Removal, Inland Rail: Beveridge to Albury – Tranche 1, and Swanson Dock West projects in Victoria, Kamay Ferry Wharves in NSW, CUF Marine Development Works and Port Dock Rail ECIs in South Australia, and the Gladstone to Fitzroy Pipeline and Aura and Harmony Trunk Infrastructure projects in Queensland. With an already strong order book, these new project awards mean the Australian business unit commences FY24 with 100% of its planned revenue for the new financial year already secured. New Zealand & Pacific The New Zealand business unit achieved a pleasing fifth-straight year of improvement across all financial metrics. Over 90% of the unit’s project portfolio is at bid margin or better, with no loss-making projects. New Zealand experienced steady work in hand growth during FY23, navigating a variable pipeline and client funding constraints to secure work. Several key projects were awarded including the high-profile State Highway 25A Taparahi Slip Remediation project following the Cyclone Gabrielle weather event in early 2023, Shotover Waste Water Treatment Plant Upgrade in Queenstown, continued works at Auckland International Airport, Warkworth to Snells pipeline with Watercare, an 8-year WWTP upgrade programme in Dunedin, Te Puke WWTP ECI, and the Wellington Sludge Minimisation project. The appointment of a Water Sector Lead and increased self-perform capability has contributed to McConnell Dowell’s sustained success in the NZ water infrastructure sector. The Pacific region saw opportunities significantly increased due to the geopolitical environment refocusing Western engagement. The ADF project provides a steady base to mobilise across the Pacific Islands, enabling the business to respond to the increased pipeline. This year, several key projects were secured including the Queen Salote International Wharf Upgrade in Tonga, a new sewer pipeline in the Solomon Islands, the ECI phase for MFAT’s PPSP Chanceries and Staff Housing project which spans seven Pacific Islands, and several new projects in American Samoa. All taking our Pacific Islands committed work forward across eleven Pacific Islands. NZP commences FY24 with a high backlog of 94% secured work, set to increase to over 100% when preferred contractor status contracts are secured. Built Environs Built Environs, the Group’s commercial building business operating in The commercial building arm of the Group increased its revenue by 60% to $229 million, consistent with a significant growth agenda in that Business Unit’s FY23 business plan. With several projects priced prior to the significant price escalation seen in the aftermath of the COVID-19 pandemic, together with several subcontractor insolvencies and the subcontractor market generally being at full capacity in Victoria, Built Environs experienced an EBIT downgrade to break even for FY23. However, the continued strong focus on new business and market exposure across each of the three regions has seen the new work won increase by 63% to a record $510 million. New projects secured include 150 Grenfell St (SA), The Queen Elizabeth Hospital (SA), Manukau Health Park Packages (NZ), Auckland Airport West Terminal Work Package 2, Mt Derrimut Station (Vic), Webb Street Station (Vic), Fawkner Leisure Centre (Vic). These new projects continue to cement Built Environs’ emerging presence in large scale health, transport and sports and leisure works. In South Australia, Built Environs handed over to the Department of Infrastructure and Transport the Golden Grove Park ‘n’ Ride project as part of the Public Transport Program Alliance.

6 Message from our CEO continued... social responsibility (CSR) initiative per project, and more than 90% of client social procurement spending targets were met or exceeded. People and Leadership Our strong leadership across the business was further enhanced by several key senior appointments, including the addition of a Project Management Office function at Group level, led by Trevor Cruden with more than 30 years’ experience in the area. Our new South East Asia Managing Director Tan Hee Wee brings a wealth of local knowledge and new industry relationships to the business, while the Australian leadership team welcomed Katrina Dodd as GM Engineering and Ryan Dodd as the new GM Queensland/Northern Territory region; both also bringing strong local network connections and reputations. Leadership teams in New Zealand and Pacific Islands and Built Environs remain largely unchanged, highlighting overall business stability. After a tumultuous post-COVID-19 period industry-wide, employee turnover has generally stabilised, with attraction and retention of top talent through career progression and leadership programs continuing to be a focus. Ongoing staff development remains a priority, with 19,779 hours of training undertaken by our employees. Looking ahead While our secured revenue is strong, there are some complexities emerging, especially in our largest market, Australia. Recent government change at the federal and state level has led to a review of priorities and major projects. Investment in social infrastructure (schools, hospitals, public housing) is set to increase in key states such as Victoria and NSW, with some of this investment likely to replace transport infrastructure funding. Similarly, all regions are planning for the inevitable energy transition and future climate and water resilience investment requirements. This again, may divert funding away from transport infrastructure. Our Horizon 2030 Strategy foresaw these trends, and the business is well placed to participate in these next waves of growth, with Work in Hand up 40% to $3.5 billion, securing expected revenue budget for FY24. The Built Environs business specialises in social infrastructure, especially schools and hospitals, while our recent focus and success in energy (e.g., Kidston Pumped Hydro and Port Kembla LNG Terminal) and water (e.g., numerous WWTP projects in NZ, Palembang WWTP in Indonesia, and SA Water Frameworks) provides the market positioning and capability platform needed for future growth. The business successfully delivered in its Victorian region the Year 9 Building for the Haileybury College and the Mt Alexander College project for the Victorian Schools Building Authority. In New Zealand, Built Environs completed the Otahuhu Logistics Park project for Logos and handed over its first health project the new Paediatric Intensive Care Units for Health New Zealand. South East Asia Revenue in South-East Asia reduced to $120 million, and the region remains the most challenging for the Group. Profit margins were adversely impacted by difficult operating conditions and supply chain constraints, with limited new work secured in the reporting period. Changes have been made in Project Leadership in the period on several of our key projects. Active projects included Jurong Regional Line (J108) and Tuas Wastewater Reclamation Works - C1A in Singapore, the Tangguh LNG, and Palembang Wastewater projects in Indonesia and FGEN LNG MultiPurpose Jetty and Gas Receiving Facility in the Philippines. Throughout the region, the construction sector has recovered to pre COVID levels in the most part, but there are still adverse effects in delivery with delays in the supply chain and depleted availability of key staff, labour, and specialist equipment. Refocusing of tender activity towards near shore marine infrastructure in FY23 has strongly positioned the BU to be awarded key projects in H1 FY24 in our key geographical markets. In FY24, the BU will continue this recentring of focus on primarily Marine opportunities in the key geographical markets of Singapore and Indonesia. Environmental, Social and Governance We have continued to deliver on our environmental, social and governance objectives aligned with our purpose of 'Providing a Better Life', by embedding our Environmental, Social and Governance (ESG) framework into our organisational decision making. Environmentally, we remain committed to reducing carbon and embracing the circular economy, including concerted efforts to minimise waste and pollution. Climate change risk or ESG proposition continues to be considered in all tenders, with an average of two environmental initiatives executed per project, and 80% of our construction and office waste diverted from landfill. We also co-developed the ‘Solarator’ - a compact containerised power plant combining solar panels, batteries and a small diesel generator, which is being used on project sites across Australia. Solarators are scalable in output and can reduce diesel consumption by up to 90% for our off-grid site facilities. On the social front, our 'Pre-employment Program’ on the New Bridgewater Bridge project is helping build the capability and capacity of Tasmania's construction industry, and providing a career kick-start for people who were either long-term unemployed, indigenous, disengaged youth, or living with a disability. The program was developed by us, funded by Keystone Tasmania, and delivered in partnership with TasTAFE and Lifeline. Overall, 56 participants (84% of the intake) graduated with job-ready skills. 26% were women and 28% were Aboriginal or Torres Strait Islander. Our Australian team also advanced their Reconciliation Action Plan (RAP) work to ‘Elevate’ level, while 100% of New Zealand projects and offices involved mana whenua. We achieved out target of at least one corporate Scott Cummins Chief Executive Officer

38 for the year ended 30 June 2023 Directors' Report The Directors present their report on the company consisting of McConnell Dowell Corporation Limited (the Company) and its controlled entities for the year ended 30 June 2023. DIRECTORS AND COMPANY SECRETARY The following persons were Directors of McConnell Dowell Corporation Limited during the financial year and up to the date of this report: Directors S.J. Flanagan (Chair), S.V. Cummins, D.J. Morrison, I. Luck, A.H. Macartney, C.D. Lock Company Secretary D.J. Morrison PRINCIPAL ACTIVITIES The principal activity of the company is infrastructure construction. There were no significant changes in the principal activities of the company during the year. CONSOLIDATED RESULT The Company has recorded varied financial results for the year ended 30 June 2023. Our underlying Australian, New Zealand and Pacific Islands businesses reported increased operating earnings and cash generation however this was overshadowed by a significant $129 million loss recorded in the South East Asia Business Unit (SEA BU), pushing the group into a $66.5 million loss for FY23 year. The main cause of the SEA BU result was the $104 million loss reported on the BLNG LNG project in the Philippines. The Batangas LNG Terminal project was an EPC contract, which was significantly delayed by COVID-19 and supply chain issues that were further exacerbated by the war in Ukraine. The EPC project is now complete, and all commercial issues settled. We continue to assist the client with final commissioning works under a separate services agreement. The business has recorded revenue growth in FY23 to $2.16 billion, mainly driven by the Australian and Built Environs business units. Project execution across Australia & NZ/Pacific has been steady, with a balanced portfolio of over 80 projects predominately performing well, with 93% profitability. Project execution conditions remain challenging in the post COVID period with high cost escalation, however, we are starting to see some easing of the escalation risk for newer projects. The business secured 40% growth in Work in Hand to $3.5 billion, providing revenue certainty for the FY24 year. KEY FINANCIAL HIGHLIGHTS IN FY23 • Revenue grew by 25% to $2.2 billion (2022: $1.7 billion) • Loss after tax $66.5 million compared to a $31 million profit in the comparative period • Work in hand up 40% to $3.5 billion with $3.2 billion new work secured during the period • Stable liquidity position with $177 million in the bank. All the business units exceeded budget cashflow with the exception of South East Asia, impacted by the deterioration of the BLNG contract resulting in a net operating cash outflow during the period. • Bonding & bank facilities of $721 million available ($562 million utilised) with dedicated support from our financial partners • Preferred positions on prospects worth over $1.0 billion plus a further $1.7 billion live tenders outstanding • Strong position to capitalise on the revenue secured for FY24 and return to profitability and future growth. OPERATIONAL PERFORMANCE Strong ESG foundations were laid throughout the year in mental health, social procurement and sustainability arenas. The group reported an excellent safety performance with the lead indicator (PHAIR) exceeding target. There were zero major environmental incidents in the period. After a successful and profitable FY22, the Group was significantly impacted by the underperformance of the Batangas LNG Terminal project (“BLNG”) in the South East Asia business unit, resulting in the Group reporting an operating loss for the period. The impact of BLNG was offset by a strong operational performance from the Australia, New Zealand & Pacific Islands, and Built Environs business units, which delivered an operating profit of $77 million. The management team responded to the underperformance with a series of operational actions including: • Establishment of a Project Management Office (PMO), which will bring added rigour to delivery performance and a back to basics focus on time, cost and risk • Enhancement of risk management procedures including risk assessment, commercial limits, project review processes, and tender technical risk reviews The Australian business unit continued to execute works across all states and in a range of industry sectors. Operationally, 95% of the strong project portfolio are profitable. The business unit achieved similar profitable levels as in FY22, however there are some execution and cost challenges in the current environment. With a strong order book, the Australian business unit commences FY24 with 100% of its planned revenue for the new financial year already secured. The New Zealand business unit achieved a fifth straight year of improvement across all financial metrics. Over 90% of the project portfolio is at bid margin or better, with no loss-making projects. The business unit commences FY24 with a high backlog of 94% secured work, set to increase to over 100% when preferred contractor status contracts are secured. Revenue in South East Asia reduced to $120 million, and the region remains the most challenging for the Group. Profit margins were adversely impacted by difficult operating conditions and supply chain constraints, with limited new work secured in the reporting period. Changes have been made in the leadership team, and in FY24, the BU will focus on primarily marine opportunities in the key geographical markets of Singapore and Indonesia. The Built Environs business unit reported a 60% increase in its revenue to $229 million on the back of solid levels of work in hand at the beginning of the financial year. The business unit's operational earnings were, however, impacted by several projects priced prior to the significant price escalation, together with several subcontractor insolvencies and the subcontractor market generally being at full capacity in Victoria. Built Environs are well positioned for FY24. Work in hand grew by 40% from June 2022 to $3.5 billion, and the group is now positioned to achieve the budgeted revenue for FY24 with 100% of the revenue secured. The business has $1 billion of preferred tender positions under negotiation. While the Group’s secured revenue is strong, there are some complexities emerging, especially in its largest market, Australia. Recent government change at federal and state level has led to a review of priorities and major projects. Investment in social infrastructure (schools, hospitals, public housing) is set to increase in key states such as Victoria and NSW, with some of this investment likely to replace transport infrastructure funding. Similarly, all regions are planning for the inevitable energy transition and future climate and water resilience investment requirements. The Group’s Horizon 2030 Strategy is aligned with these trends, and the business is well placed to participate in these next waves of growth.

39 DIVIDENDS A dividend of $15.75 million (2022 – $12.5 million) was declared and paid during the year ended 30 June 2023 to the parent company shareholder. SIGNIFICANT CHANGES IN THE STATE OF AFFAIRS There were no significant changes in the state of affairs of the company other than that referred to in the financial statements and notes following. INDEMNIFICATION AND INSURANCE OF DIRECTORS AND OFFICERS During the financial year the company indemnified and paid an insurance premium in respect of a D&O policy insuring the directors and officers of the group companies for certain liabilities and legal costs and expenses that may be incurred by those individuals in their capacity as directors or officers, to the extent permitted by law. The contract of insurance prohibits disclosure of the amount of the premium paid by the company. SAFETY AND ENVIRONMENTAL REGULATIONS The company is committed to the highest standard of environmental and workplace safety performance reasonably practicable. The company’s performance in respect to its compliance with its policies and operating procedures to ensure its obligations in this regard are met is reported to the Executive Committee (Exco). The company is subject to various environmental and safety regulations under either Commonwealth, State or other international legislation. The Board believes the company has adequate systems in place for the management of its environmental and workplace safety compliance and operational risks and is not aware of any material breach of relevant legal and regulatory requirements as they apply to the company other than those already disclosed in this report. LIKELY DEVELOPMENTS AND EXPECTED RESULTS OF COMPANY In the opinion of the directors, it would prejudice the interests of the company if any further information on reasonable and material developments in the operations of the company and the expected results of operations were included herein, and the omission of such information is hereby disclosed. EVENTS SUBSEQUENT TO BALANCE DATE No significant events have occurred subsequent to balance date. ROUNDING The amounts contained in this report and in the financial report have been rounded to the nearest thousand dollars (where rounding is applicable) and where noted ($’000’s) under the option available to the company under ASIC Corporations (Rounding in Financial/Directors' Reports) Instrument 2016/191. The company is an entity to which the Corporations Instrument applies. NON-AUDIT SERVICES The directors are satisfied that the provision of non-audit services is compatible with the general standard of independence for auditors imposed by the Corporations Act 2001. The nature and scope of each type of non-audit service provided means that auditor independence was not compromised. KPMG Australia has not received or are not due to receive the any amounts for the provision of non-audit services. AUDITOR INDEPENDENCE DECLARATION The company has obtained an Auditor’s Independence Declaration from KPMG Australia. The Auditor’s Independence Declaration is located on the following page. The annual financial statements which appear on pages 41 to 90 were approved by the directors by resolution dated 21 August 2023 and are signed on their behalf. GOING CONCERN AND LIQUIDITY In determining the appropriate basis of preparation of the financial statements, the Directors are required to consider whether the Group can continue in operational existence for the near future. The Company enters FY24 with increased levels of work in hand of $3.5 billion following significant project wins in Australia, New Zealand and Built Environs. At the date of this report the Company also has $1 billion of opportunities that are in sole source negotiations or in Early Contractor involvement stage and therefore it is probable these will be converted into contracted projects. In addition, there are a further $1.7 billion of other outstanding tenders and a further $6 billion tenders expected in FY24 which will provide a solid base for future revenue. The Directors have reviewed the business plans and detailed financial budgets for the year ending 30 June 2024 and beyond. The construction markets of Australia, New Zealand and Built Environs are healthy, however there is a level of uncertainty. The Built Environs pipeline in social infrastructure remains strong, however government civil infrastructure spend in New South Wales and in Victoria (both Australian regions) is decreasing. A reducing market will increase the competitiveness in tendering for work. The Company benefits from having diversity in locations and type of work performed allowing it to position itself to maximise the opportunities best fit for the organisation. These detailed financial budgets and business plans that are being implemented by management indicate that the Group will have sufficient liquidity resources for the near future. The Company has met its banking covenants for 30 June 2023 resulting in no breaches at year-end and current forecasts do not indicate any breaches in the upcoming financial quarters. The Group retains the support of its lenders, guarantee providers, and insurance bonding providers. The Directors have considered the business plans and detailed financial budgets, including all available information, and whilst significant estimates and judgements including the impacts of the wider economic environment are always and will continue to be required, the Directors are of the opinion that the going concern assumption is appropriate in the preparation of the financial statements.

46 Notes to the annual financial statements for the year ended 30 June 2023 COMPANY DETAILS McConnell Dowell Corporation Limited (the Company) is a public unlisted for-profit company incorporated and domiciled in Australia. The Company’s registered place of business is Level 3, 109 Burwood Road, Hawthorn, Victoria, Australia. The ultimate Australian parent is Aveng Australia Holdings Pty Ltd. The ultimate parent is Aveng Limited (a company incorporated in South Africa). BASIS OF PREPARATION The financial report is a general-purpose financial report, which has been prepared in accordance with the Corporations Act 2001, Australian Accounting Standards and other authoritative pronouncements of the Australian Accounting Standards Board (AASB). The financial report of the Consolidated Entity also complies with International Financial Reporting Standards (IFRS) as adopted by the International Accounting Standards Board (IASB). The financial report has also been prepared on a historical cost basis, except for certain financial instruments (when applicable) which have been measured at fair value. Where necessary, comparative figures have been reclassified and repositioned for consistency with current year disclosures. The financial report is presented in Australian dollars and all values are rounded to the nearest thousand ($000’s) except when otherwise indicated in accordance with ASIC Corporations (Rounding in Financial/ Directors' Reports) Instrument 2016/191. The financial report was approved by a resolution of the Directors of the Company on 21 August 2023. Going Concern In determining the appropriate basis of preparation of the financial statements, the Directors are required to consider whether the Group can continue in operational existence for the foreseeable future. The Company enters FY24 with increased levels of work in hand of $3.5 billion following significant project wins in Australia, New Zealand and Built Environs. At the date of this report the Company also has $1 billion of opportunities (based on current contract value) that are in sole source negotiations or in Early Contractor involvement stage and therefore it is probable these will be converted into contracted projects. In addition, there are a further $1.8 billion of other outstanding tenders and a further $7.5 billion tenders expected in FY24 which will provide a solid base for future growth. The Directors have reviewed business plans and detailed financial budgets for the year ending 30 June 2024 and beyond. The construction markets of Australia, New Zealand and Built Environs are healthy, however there is a level of uncertainty. The Built Environs pipeline in social infrastructure remains strong, however Government Civil infrastructure spend in New South Wales and in Victoria(all Australian regions) is decreasing. A reducing market will increase the competitiveness in tendering for work. The Company benefits from having diversity in locations and type of work performed allowing the Company to position itself to maximise the opportunities best fit for the organisation. These detailed financial budgets and business plans that are being implemented by management indicate that the Group will have sufficient liquidity resources for the foreseeable future. The Company has renegotiated its banking covenants for 30 June 2023 resulting in no breaches at year-end and current forecasts do not indicate any breaches in the upcoming financial quarters. The Group retains the support of its lenders, guarantee providers, and insurance bonding providers. The Directors have considered the business plans and detailed financial budgets, including all available information, and whilst significant estimates and judgements including the impacts of the wider economic environment (including COVID-19) are always and will continue to be required the Directors are of the opinion that the going concern assumption is appropriate in the preparation of the financial statements. STATEMENT OF COMPLIANCE The financial report complies with Australian Accounting Standards and International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB). BASIS OF CONSOLIDATION The consolidated financial statements include the financial statements of McConnell Dowell Corporation Limited and its subsidiaries as at 30 June each year (the Group). Control over a subsidiary is achieved when the Group is exposed or has the rights to variable returns from its involvement with the subsidiary and has the ability to affect those returns through its power over the subsidiary. Specifically, the Group deems it controls a subsidiary if and only if the Group has: • Power over the subsidiary (i.e., existing rights that give it the current ability to direct the relevant activities of the subsidiary) • Exposure, or rights, to variable returns from its involvement with the subsidiary, and • The ability to use its power over the subsidiary to affect its returns When the Group has less than a majority of the voting or similar rights of a subsidiary, the Group considers all relevant facts and circumstances in assessing whether it has power over a subsidiary, including; • The contractual arrangement with the other vote holders of the subsidiary • Rights arising from the other contractual arrangements • The Group’s voting rights and potential voting rights The Group reassess whether or not it controls a subsidiary if facts and circumstances indicate that there are changes to one or more of the three elements of control. Subsidiaries are fully consolidated from the date on which control is obtained by the Group and cease to be consolidated from the date on which control is transferred out of the Group. The parent's investments in controlled entities are initially recognised at cost and subsequently measured at cost, less any impairment charges. 1. Accounting policies

47 Non-controlling interests not held by the Group are allocated their share of net profit after tax and each component of other comprehensive income and are presented within equity in the consolidated statement of financial position, separately from parent shareholders’ equity. All intercompany transactions and balances, income and expenses, and profits and losses resulting from intra-group transactions are eliminated on consolidation. BUSINESS COMBINATIONS Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the aggregate of the consideration transferred, measured at acquisition date fair value and the amount of any non-controlling interest in the acquiree. For each business combination, the Group elects whether it measures the non-controlling interest in the acquiree either at fair value or at the proportionate share of the acquiree's identifiable net assets. Acquisition costs incurred are expensed and included in administrative expenses. When the Group acquires a business, it assesses the financial assets and liabilities assumed for appropriate classification and designation in accordance with the contractual terms, economic conditions, the Group’s operating or accounting policies and other pertinent conditions as at the acquisition date. This includes the separation of embedded derivatives in host contracts by the acquiree. If the business combination is achieved in stages, the acquisition date fair value of the acquirer's previously held equity interest in the acquiree is remeasured at fair value as at the acquisition date through profit or loss. Any contingent consideration to be transferred by the acquirer will be recognised at fair value at the acquisition date. Subsequent changes to the fair value of the contingent consideration which is deemed to be an asset or liability will be recognised in accordance with AASB 9 either in profit or loss or in other comprehensive income. If the contingent consideration is classified as equity, it shall not be remeasured. FOREIGN CURRENCY TRANSLATION Functional and presentation currency Both the functional and presentation currency of McConnell Dowell Corporation Limited and its Australian subsidiaries is Australian dollars ($). Where a subsidiary’s functional currency is a different denomination it is translated to the presentation currency (see below). Transactions and balances Transactions in foreign currencies are initially recorded in the functional currency by applying the exchange rates ruling at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are retranslated at the rate of exchange ruling at the reporting date. All differences arising on settlement or translation of monetary items are taken to the statement of profit or loss. Non-monetary items that are measured in terms of historical cost in a foreign currency are translated using the exchange rate as at the date of the initial transaction. Non-monetary items measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value was determined. Translation of group companies’ functional currency to group presentation currency On consolidation the assets and liabilities of foreign entities are translated into Australian dollars at rates of exchange prevailing at the reporting date. Income, expenditure and cash flow items are translated into Australian dollars at weighted average rates. Exchange variations arising on translation for consolidation are recognised in the foreign currency translation reserve in equity, through other comprehensive income. If a subsidiary were sold, such translation differences are recognised in the statement of profit or loss as part of the cumulative gain or loss on disposal. FINANCIAL INSTRUMENTS Financial Assets Initial recognition and measurement The Group initially recognises financial assets when the Group becomes a party to the contractual provisions of the instrument. Financial assets are initially measured at fair value plus in the case of assets not measured at fair value through profit or loss, directly attributable transaction costs. Subsequently financial assets, excluding derivatives, are classified as measured at amortised cost or fair value, depending on the Group’s business model for managing the financial asset and the contractual cash flow characteristics of the financial asset. Derivatives are subsequently measured at fair value through profit or loss. Changes in the fair value of derivatives used to economically hedge the Group’s foreign exchange exposure are recognised in other earnings in the earnings or loss component of the statement of comprehensive earnings. A financial asset qualifies for amortised cost, using the effective interest method net of any impairment loss if it meets both of the following conditions: • the asset is held within a business model whose objective is to hold assets in order to collect contractual cash flows; and • the contractual terms of the financial asset give rise, on specified dates, to cash flows that are solely payments of principal and interest on the principal amount outstanding. If a financial asset does not meet both of these conditions, it is measured at fair value. The assessment of business model is made at portfolio level as this reflects best the way the business is managed, and information is provided to management. Purchases or sales of financial assets that require delivery of assets within a time frame established by regulation or convention in the marketplace are recognised on the trade date, i.e., the date that the Group commits to purchase or sell the asset. The Group’s financial assets are classified as trade and other receivables, amounts due from contract customers, and cash and bank balances.
