CURRENCY OF PRESENTATION AND DEFINITIONS

“Orbital” means Orbital Corporation Limited, a corporation incorporated under the laws of the State of Western Australia, Commonwealth of Australia and its consolidated subsidiaries.

See the Glossary at the end of this Annual Report for definitions of technical terms.

Orbital publishes its consolidated financial statements in Australian dollars. In this Annual Report, unless otherwise specified or the context requires, references to the “US$” or “US Dollars” are to United States dollars and references to “$” or “A$” are to Australian dollars. For the convenience of the reader, this Annual Report contains translations of Australian dollar amounts into United States dollars at the rate or rates indicated. Unless otherwise stated, the translations of Australian dollars into US dollars have been made at the WM/Reuters Australian Dollar Fix Rate, for the dates specified. These translations should not be construed as representations that the A$ amounts actually represent the US$ amounts or could be converted into US$ at the conversion rate used.

FORWARD LOOKING STATEMENTS

This Annual Report contains “forward-looking statements” as that term is used in the Private Securities Litigation Reform Act of 1995. Forward-looking statements are based on current expectations rather than historical facts and they are indicated by words or phrases such as “anticipate”, “estimate”, “expect”, “project”, “believe”, “intend”, “envision” and similar words or phrases. These forward-looking statements involve known and unknown risks, uncertainties and other factors, many of which are beyond Orbital’s control, that may cause actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements. Some of the factors that would affect our financial performance, cause actual results to differ from our estimates, or underlie such forward-looking statements, are set forth in various places in this report including, but not limited to, Item 3 “Key Information – Risk Factors”; Item 4 “Information on the Company” and Item 5 “Operating and Financial Review and Prospects”.

These risks include, but are not limited to, the following:

• reduction in fees from customers for our consulting, development and testing services;

• the impact of exchange rate movements on licence and royalty receipts;

• changes in engine manufacturers’ preferences towards FlexDi ^TM Technology;

• increased competition from existing or new engine technologies;

• changes in engine emissions standards or other environmental laws in countries where Orbital licences or plans to licence FlexDi ^TM Technology;

• the rate of market penetration of Ford’s EcoLPI Falcon that is expected to drive a significant portion of revenues going forward;

• the rate of market penetration of Orbital’s next generation Liquid LPG fuel systems;

• a downturn in general economic conditions in industries and markets where Orbital licences or plans to licence FlexDi^TM Technology; and

• the cost of any product liability or intellectual property suits against Orbital.

Orbital undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. Because of the risks, uncertainties and other factors discussed above, such forward-looking statements should not be unduly relied upon.

The Australian dollar is convertible into US dollars at freely floating rates. There are currently no restrictions on the flow of Australian currency between Australia and the United States.

Fluctuations in the exchange rate between the Australian dollar and the US dollar may affect Orbital’s earnings, the book value of its assets and its shareholders’ equity as expressed in Australian and US dollars, and consequently may affect the market price for the American Depositary Shares (the “ADSs”). In addition, fluctuations in the exchange rate between the Australian dollar and the US dollar will affect the US dollar equivalent of the Australian dollar price of Orbital’s ordinary shares on the ASX and, as a result, are likely to affect the market price of Orbital’s ADSs in the United States. See “Item 3. Key Information – Risk Factors – Fluctuations in exchange rates may have a material adverse effect on us”. Any fluctuations will also affect the conversion into US dollars by the Depositary of cash dividends, if any, paid in Australian dollars on the ordinary shares represented by the ADSs.

To date, Orbital has denominated and received most of its earnings from licence, development and supply agreements in US dollars. Cash and investments have been denominated in a combination of US dollars and Australian dollars and a significant proportion of expenditure in past years has been denominated in US dollars. However, presently most of Orbital’s expenditure is denominated in Australian dollars. In periods when the US dollar appreciates against the Australian dollar, the Australian dollar conversion of the US dollar earnings under the licence and supply agreements may be materially enhanced. However, when the US dollar depreciates against the Australian dollar, Australian dollar conversion of the US dollar earnings under the licence and supply agreements may be materially reduced. Orbital may, where appropriate, enter into forward foreign currency hedging contracts to minimise currency exposure particularly in relation to royalties received in US dollars and Euros and their conversion into Australian dollars to satisfy Australian dollar expenditures and realise profits in Australian dollars.

Orbital’s financial statements for the years ended June 30, 2011, 2010 and 2009 have been prepared in accordance with Australian Accounting Standards (“AASB”), which Orbital adopted on July 1, 2005. In complying with AASB, Orbital is also in compliance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board.

The selected consolidated financial data in accordance with IFRS below expressed in Australian dollars has been derived from Orbital’s consolidated financial statements for the years ended June 30, 2011, 2010, 2009, 2008, and 2007, which have been audited by Ernst & Young (2011, 2010, 2009 and 2008) and KPMG (2007), both independent registered public accounting firms. The consolidated financial statements as of June 30, 2011 and 2010 and for the years ended June 30, 2011, 2010 and 2009, and the Report of independent registered public accounting firm thereon, are included elsewhere in this report, see F1 – F65. The consolidated financial statements as of June 30, 2009, 2008 and 2007 and for the years ended June 30, 2008 and 2007 and the Report of independent registered public accounting firm thereon have not been included in this report.

(1) For the convenience of the reader the 2011 Statement of Financial Position and Income Statement data has been translated at the WM/Reuters Australian Dollar Fix Rate at 4:00pm (Sydney) for Australian dollars on September 30, 2011 which was US$0.9781 = A$1.00. Such translations are unaudited and provided for information purposes only. These translations should not be construed as representations of the amount that the Australian dollar amounts actually represent US dollar amounts, or could be converted into US dollars at the conversion rate used.

(2) The long-term debt consists principally of a loan facility with the State of Western Australia (A$14.3 million for 2011 and 2010; A$19.0 million for 2009, 2008 and 2007). In January 2010, Orbital reached agreement with the State of Western Australia through the Department of Commerce for the restructure of the Non-Interest Bearing Loan.

Under the agreed restructure the original loan has been terminated and replaced by a new loan of $14,346,000, which includes the following terms and conditions.

• Term – 2010 to 2025.

• Repayments – Commencing May 2010 at $200,000 per annum.

• Repayments – Increasing annually to a maximum of $2,100,000 per annum in 2023.

• Interest free.

(for additional information see note 26 to the Consolidated Financial Statements).

(3) The shares exercisable under the Orbital employee share plan have no material dilutive effect in respect of any year. At June 30, 2011 there were 48,482,558 ordinary shares on issue.

(4) On October 28, 2010 the shareholders in Annual General Meeting approved the consolidation of ordinary shares on the basis that every ten ordinary shares be consolidated into one ordinary share, and where this consolidation results in a fraction of a share being held by a shareholder, the directors of the Company be authorised to round that fraction up to the nearest whole share. The share consolidation became effective on October 28, 2010. The effect of the share consolidation has been retroactively applied to the number of shares and Earnings per share calculations above.

Risk Factors

• We have a history of operating losses.

Orbital experienced operating losses over a number of years prior to the 2006 fiscal year and again in the 2009 fiscal year, as a result of which the Company’s net assets were significantly reduced. The Company has positive shareholders’ equity and we believe that the company is operating on a going concern basis. However, if we were to incur future losses, we may not be able to continue our operations.

- 5 -

• Our customers may reduce their out-sourced consulting services expenditure.

A major source of Orbital’s revenue is the provision of consulting services to customers in the automotive, motorcycle and marine and recreation sectors. Customers utilise Orbital’s services as they either do not have the necessary skills in-house or their internal resources are overloaded. The sourcing of overload work is very dependent on the state of the market. In the event of a market downturn, this source of work would diminish. Reduction by Orbital’s customers of their expenditure on out-sourced consulting services may substantially lessen the revenue received by Orbital.

• The future fees we receive under agreements with Original Equipment Manufacturers (“OEMs”) may be substantially less than the fees received in recent years.

Agreements are entered into with vehicle, engine and component manufacturers and financing parties that grant rights to manufacture, use and sell products that utilise Orbital Combustion Process (“FlexDi ^TM”) Technology. In the fiscal year ended June 30, 2011, royalty and licence fees revenue generated from the seventeen current licensed users of FlexDi ^TM technology and their affiliates accounted for approximately 7% of Orbital’s consolidated operating revenues. During the last two fiscal years, royalty and licence fees income from licensed users accounted for approximately 7% of Orbital’s consolidated operating revenues.

Orbital has already received and brought to account through revenue a majority of the total lump sum fees due under its existing licence agreements. The amount of additional lump sum fees earned under these agreements will depend on several factors, including the commercialisation of products incorporating FlexDi ^TM Technology, whether the licensees expand the territories or volumes covered by the agreements and whether additional consulting or engine development services are provided. As a result, the remaining fees received by Orbital under existing agreements may be substantially less than the fees received in prior years.

• The failure to obtain new customers or receive royalties from existing or new customers could have a material adverse effect on us.

The agreements with OEMs usually entitle Orbital to receive ongoing royalties when licensees sell engines incorporating FlexDi ^TM Technology. The total royalties paid to Orbital depend on whether manufacturers succeed in selling these engines to consumers. As at September 30, 2011, seven of Orbital’s seventeen licensed users are in commercial production and selling products using FlexDi ^TM Technology. For the year ended June 30, 2011, Orbital has not received any royalty payments under any of its other agreements.

Orbital may not be able to enter into additional agreements with new customers. In addition, current licensees may choose not to commercially produce engines incorporating FlexDi ^TM Technology, and those who do may not succeed in selling these products to consumers. The failure to obtain new customers or receive royalties from existing or new customers could have a material adverse effect on Orbital’s business and results of operations.

• We rely on a small number of key customers.

Orbital relies on a small number of key customers for the majority of its revenues. Three customers (Ford Australia and the top two engineering customers) accounted for 41% of total revenue in fiscal 2011. The loss of Ford Australia could have a material adverse effect on Orbital’s business and results of operations. Three customers (Ford Australia and the top two engineering customers) accounted for 43% of total revenue in fiscal 2010.

Synerject, which makes a significant contribution to Orbital’s overall result, is also reliant on a small number of key customers for the majority of its revenues. In fiscal 2011, two customers (BRP and Mercury Marine) accounted for 54% (2010: two customers (BRP and Kymco) accounted for 57%) of Synerject’s total revenue.

- 6 -

• We may not be able to successfully complete the production testing programs for the application of FlexDi Technology to customer engines.

Orbital and its licensees engage in production testing programs, which typically last two to four years, for the application of FlexDi Technology to customer engines. These tests must be successfully completed before manufacturers will consider committing the large capital amounts needed to modify existing or build new engine manufacturing plants. Orbital generally receives consulting fees for undertaking these programs.

Orbital may not be able to complete these testing programs successfully or without unforeseen problems or delays. As a result there can be no certainty that further products using FlexDi Technology will be introduced into the market or that Orbital will continue to receive consulting fees for performing these production programs.

• The market may not accept FlexDi Technology.

Many factors will influence whether Orbital’s licensees decide to produce engines commercially using FlexDi Technology. These include the cost of adapting existing facilities or building new manufacturing facilities, the cost of producing each system and the reliability and efficiency of FlexDi Technology. Manufacturers also will evaluate competing technologies and consider how government fuel economy and emissions standards in different countries may favour one technology over another. If manufacturers begin commercial production using FlexDi Technology, the number of engines sold will depend on market acceptance. Many of these factors are beyond Orbital’s control, but will ultimately affect the amount of royalties received. If licensees decide not to use FlexDi Technology commercially or consumers choose not to buy products incorporating FlexDi Technology, there would be a material adverse effect on Orbital’s business and results of operations.

• Our sales of LPG Vapouriser Kits may drop.

The sale of LPG Vapouriser kits is a significant portion of our revenue (2011: 35%, 2010: 36%). Changes in emissions regulations in Australia that came into effect on July 1, 2010 prohibit the manufacture of new vehicles with vapouriser kits. Sales to the aftermarket will continue past June 30, 2010 as retrofit conversions can still be undertaken on vehicles manufactured before June 30, 2010. Orbital has developed a Liquid LPG fuel system which complies with the Australian emissions regulations noted above.

• Our sales of Liquid LPG Fuel Systems may not be to plan.

In fiscal 2010, we invested approximately $1.0 million in the development of the next generation Liquid LPG fuel systems. Sales of these kits have not been at a high enough volume and/or high enough margin to recoup these investments and as such $1,065,000 of previously capitalised development expenditure was written off in fiscal 2011. The overall level of conversion of vehicles to LPG in Australia is considerably lower than in recent years and this depressed market may continue resulting in less demand for our Liquid LPG fuel systems.

In May 2011 Orbital acquired the business of Sprint Gas Australia (see note 38 to the financial statements). Sprint Gas distributes LPG products to the aftermarket. Sprint Gas will also be affected by the level of LPG conversions in Australia.

• We have a large concentration of LPG fuel system sales to a single customer.

Our major customer for LPG fuel systems is Ford Australia. Demand for large sedans may drop which will effect the level of our sales to Ford. Ford have recently launched their EcoLPi Ford Falcon vehicle range equipped with Orbital’s Liquid LPG system. Orbital’s sales to Ford will depend on the successful launch and market acceptance of the EcoLPi.

• We may not be able to fund the capital and working capital requirements necessary for our business.

Orbital requires significant capital amounts to conduct its business. For example, Orbital expects to incur on-going research and development costs and operating costs to enhance the FlexDi Technology and Liquid LPG fuel systems products. In the past, these costs have been paid with a combination of operating revenues, equity injections, debt and other financing. However, there can be no assurance that Orbital will have sufficient operating revenues to fund future costs or that outside financing will be available at affordable prices, or at all. A failure to obtain sufficient financing for ongoing costs could prevent Orbital from carrying out business plans on time and give an advantage to competitors with greater financial resources. If a shortage of financing causes long delays in the further development and commercialisation of FlexDi Technology, licensees could choose not to build engines with FlexDi Technologies or to use competing technologies. This could have a material adverse effect on Orbital’s business and results of operations.

- 7 -

• We may not be able to protect our intellectual property rights.

Orbital has obtained patents on many aspects of its FlexDi Technology, and has applied for additional patents on other aspects of its technologies. Orbital’s success depends, in part, on its ability to protect its technology and products under applicable intellectual property laws.

Orbital is not a party to any present patent or intellectual property litigation, but in the future may be sued by other parties that claim Orbital infringes their patent rights or other rights, or may need to sue other parties to enforce its patent or other intellectual property rights. In the event of being sued by other parties, if proved, these claims could have a material adverse effect upon Orbital. Even if Orbital won any of these suits, the management time and legal expenses required to defend these claims could have an adverse effect on Orbital’s future operating results. Orbital also has trade secrets and know-how, which are not patentable but are still important to Orbital’s business. Orbital seeks to protect these rights through confidentiality agreements and contractual protections. These arrangements may not protect Orbital from unauthorised use or disclosure of its trade secrets and know-how.

• Our share price may be volatile.

The price of Orbital’s ordinary shares on the Australian Stock Exchange (“ASX”) and the OTC Bulletin Board have experienced historic volatility. In addition, technology stocks traded in both markets have experienced substantial price and volume fluctuations from time to time, even though these changes were sometimes unrelated to the operating performance of specific companies. Announcements of operating results or technical innovations by Orbital or its competitors, including reports or announcements about FlexDi Technology, may have a material effect on the market price of the ordinaryshares or the ADSs. On August 25, 2011 Orbital’s ADSs commenced trading on the NYSE Amex under the symbol “OBT”. On September 30, 2011, the closing price of Orbital’s ordinary shares on the ASX was A$0.33. The closing price on June 30, 2011 was A$0.25. The closing price of the ADSs on the NYSE Amex on September 30, 2011 was US$4.35, an increase of approximately 0.5% from the closing price of US$4.33 for the ADSs on the OTC Bulletin Board on June 30, 2011. See Item 9. – “The Offer and Listing – Nature of Trading Market”.

• A large product liability or professional indemnity judgement could have a material adverse effect on us.

Orbital is subject to business risk from product liability or professional indemnity suits if third parties claim that defects in FlexDi Technology or in consulting services provided by Orbital resulted in personal injury or other losses. Orbital may also be required to indemnify licensees for claims arising from alleged defects in products, which use FlexDi Technology or are designed or manufactured by Orbital. Licensees are, however, required to indemnify us from liabilities caused by defects in products not manufactured by Orbital.

Orbital believes that sufficient product liability and indemnity insurance is held for the range of products and services currently provided to licensees and other customers, but sufficient coverage may not be able to be obtained in the future at affordable costs, or at all. Even if Orbital has such insurance, a judgement against us in a large product liability or professional indemnity suit could have a material adverse effect on Orbital’s business or financial condition.

• FlexDi Technology may not be able to compete successfully against other engine technologies.

Orbital faces significant competition from automobile and engine manufacturers and consulting firms specialising in internal combustion engine technology. Many of these competitors have substantially greater financial, marketing and technological resources than Orbital.

Orbital’s commercial success depends in part upon whether FlexDi Technology can compete successfully against both existing and new engine technologies, including new technologies that are similar to FlexDi Technology. To achieve further commercial success, FlexDi Technology will need to displace current four-stroke and two-stroke internal combustion engine technologies, which have a dominant market position. Current four-stroke and two-stroke engine technologies may continue to dominate the engine market, or they may be replaced by new technologies other than FlexDi Technology. Orbital’s competitors may develop products that are technically superior to Orbital’s products or more acceptable to the market. This could reduce Orbital’s market share or make FlexDi Technology less attractive or obsolete, which would have a material adverse effect on Orbital’s business and results of operations.

• Fluctuations in exchange rates may have a material adverse effect on us.

Orbital records its transactions and prepares its financial statements in Australian dollars. Most of Orbital’s earnings from licence and supply agreements are in US dollars. Cash and investments are denominated in both Australian and US dollars. Approximately 86% of Orbital’s expenditures are denominated in Australian dollars. When the US dollar appreciates against the Australian dollar, the US dollar earnings would convert into more Australian dollars. However, when the US dollar depreciates against the Australian dollar the US dollar earnings would convert into fewer Australian dollars. Fluctuations in exchange rates between the Australian dollar and the US dollar may also affect the book value of assets and the amount of shareholders’ equity. To reduce its potential currency exposure, Orbital has from time to time entered into forward foreign currency exchange contracts to fix, in Australian dollars, the majority of forecast US dollar royalty and consulting services fee receipts. Details of Orbital’s total foreign currency forward exchange contracts as of June 30, 2011 are contained in Item 5. – “Operating and Financial Review and Prospects – Foreign currency exchange sensitivity”. As at September 30, 2011, Orbital’s outstanding forward foreign currency exchange contracts totalled US$nil. See also Item 3 – “Key Information – Exchange Rate Information” above.

• We may not be able to comply with future governmental regulations.

Products using FlexDi Technology must comply with many emissions, fuel economy and other regulations in Australia, the US and other countries. Based on internal testing, Orbital believes that products using FlexDi Technology will be able to meet current emissions and fuel economy standards in the countries that are Orbital’s most important markets. The effects of any future regulations on Orbital’s business or results of operations cannot be predicted. However, if Orbital were unable to comply with any material new regulations in Australia, the US or other key markets, this could delay further commercialisation of FlexDi Technology and have a material adverse effect on Orbital’s business and results of operations.

• Classification as a “PFIC” would result in adverse tax treatment to our US shareholders.

Under US federal tax laws, a foreign corporation is treated as a passive foreign investment company (“PFIC”) if 50% or more of its assets or 75% or more of its income is passive. Historically, Orbital has not been treated as a PFIC and currently believes that it is not a PFIC. This is, however, a factual determination made annually, which could change, based upon future developments or changes in Orbital’s gross income or the value of its assets. If Orbital were classified as a PFIC in any taxable year, a US holder of ADSs or ordinary shares or ADSs would be subject to special rules. These rules are intended to reduce or eliminate any benefit from the deferral of US income tax that a US holder could derive if the foreign company does not distribute all of its earnings on a current basis. See Item 10. – “Additional Information – United States Federal Income Taxation”.

Orbital is an international developer of engine and related technologies, providing research, design and development services for the world’s producers of powertrains and engine management systems for application in motorcycles, marine and recreational vehicles, automobiles and trucks. Orbital’s principal operations in Perth, Western Australia, provide a world-class facility with capabilities in design, manufacturing, development and testing of engines and powertrains. Orbital provides its customers with leading edge engineering expertise. Headquartered in Perth, Western Australia, Orbital stock is traded on the Australian Stock Exchange (OEC), the NYSE Amex (OBT) (since August 25, 2011) and was traded on the OTC Bulletin Board (OBTMY) (until August 25, 2011).

Orbital’s beginnings date to the late 1960s, when Ralph Sarich, Orbital’s founder, began development of a rotary internal combustion engine called the Orbital Engine. Mr Sarich entered a partnership, known as the Sarich Design and Development Partnership, with two other individuals for the purpose of developing, patenting and marketing the Orbital Engine. In November 1972, the partnership entered into a joint venture with The Broken Hill Proprietary Company Limited (“BHP��), then one of Australia’s largest companies. Under that joint venture, in which each of the partnership and BHP had a 50% interest, Orbital Engine Company (Australia) Pty Ltd (now Orbital Australia Pty Ltd) was established in January 1973, for the development and commercialisation of the Orbital Engine.

In 1978, the partnership assigned its interest in Orbital Engine Company (Australia) Pty Ltd to the Sarich Design and Development Unit Trust (the “Trust”). In 1984, the Trust publicly offered some of its interest in Orbital Engine Company (Australia) Pty Ltd through the listing on the Australian Stock Exchange (“ASX”) of the Sarich Technologies Trust (“STT”). In December 1988, STT was converted to an ASX listed company, Sarich Technologies Limited. In May 1989, BHP exchanged its 50% equity interest in Orbital Engine Company (Australia) Pty Ltd for a 35% shareholding in Sarich Technologies Limited, reflecting BHP’s rights to income under the original joint venture agreement with the partnership and certain debt owing from Orbital Engine Company (Australia) Pty Ltd to BHP. In November 1990, Sarich Technologies Limited changed its name to Orbital Engine Corporation Limited.

- 10 -

In the period between 1973 and 1983, Orbital established a team of engineers and technicians and developed fuel injection and combustion technology that enhanced the performance of the rotary Orbital Engine, culminating with General Motors Corporation entering into an agreement in 1983 to evaluate the Orbital Engine. During this period, Orbital recognised that its fuel injection and combustion technology could also be applied to a conventional two-stroke engine to reduce many of its shortcomings.

In 1983, Orbital determined that the application of its technology to two-stroke engines had the potential for greater commercial return and market acceptance than the rotary Orbital Engine due, among other things, to the commercial barrier of requiring completely new manufacturing processes and facilities to produce the rotary Orbital Engine. As a consequence, Orbital decided to cease development of the rotary Orbital Engine in favour of applying its fuel injection and combustion technology to two-stroke engines.

In December 1991, Orbital offered for sale 2,890,000 American Depositary Shares (“ADSs”) (representing 23,120,000 ordinary shares in Orbital) and BHP offered for sale 510,000 ADSs representing 4,080,000 ordinary shares in Orbital. These ADSs were listed on the NYSE at that time. BHP sold its entire shareholding by December 1999.

In June 1997, Orbital and Siemens-VDO Automotive established a joint venture, Synerject LLC, to design, develop, manufacture, distribute and sell fuel rail assemblies incorporating FlexDi Technology. See “Strategic Alliances – Continental” below.

Effective July 1, 2004, Orbital’s ADSs were de-listed from the NYSE as the continued listing requirements relating to market capitalization and shareholder equity were not met. Trading in the Company’s ADSs was transferred to the OTC Bulletin Board with effect from July 1, 2004. On August 25, 2011 Orbital listed on the NYSE Amex and ceased trading on the OTC Bulletin Board. As of September 30, 2011, approximately 21% of Orbital’s outstanding shares were held in the form of ADSs traded on the NYSE Amex. See Item 9. – “The Offer and Listing – Nature of Trading Market”.

The Company’s principal capital expenditures since July 1, 2008 have consisted of ongoing improvements to test facilities and equipment ($5.101 million), including the construction of the Heavy Duty Engine Testing Facility ($3.508 million).

In June 2008, Orbital acquired the business assets of Boral Alternative Fuel Systems (renamed Orbital Autogas Systems – OAGS), a tier 1 supplier of LPG fuels systems, for $1.758 million.

In May 2011, Orbital acquired, for an initial investment of $2.000 million, 55% of the voting shares of Sprint Gas (Aust) Pty Ltd, a new company incorporated to acquire the operating business of Sprint Gas, an Australian business specialising in the importation and wholesaling of LPG Fuel systems to the aftermarket.

Business Overview

Orbital’s strategy is as follows:

• Expand into an alternate fuels LPG business building on the Orbital Autogas Systems and Sprint Gas acquisitions.

• Continue our commitment to grow Synerject as a profitable systems provider in the non-automotive markets and increase the value of this asset.

• Target R&D to enhance FlexDi products to respond to requests raised by existing and potential customers who require improved performance or lower unit cost to extend the roll out of our technology. In turn this will enhance the company’s intellectual property portfolio.

• Judicious acquisitions, where we can add shareholder value.

• Expand Orbital’s automotive consulting services by winning projects and establishing strategic alliances with Australian and Asian partners.

• Achieve future growth of licences and royalties for FlexDi in niche markets.

• Targeted growth in liquid natural gas/compressed natural gas for the Australian and Asian heavy transport sector.

Orbital technology has been commercialised in the motorcycle, marine and recreational vehicle markets. Orbital’s goal is to broaden the application of Orbital technology in these and other markets. Orbital’s strategy is to continue to participate actively, where appropriate, in the commercialisation of FlexDi Technology to reduce risks and advance the rate of adoption of this technology while targeting growth in the alternative fuels industry.

Orbital Combustion Process (“FlexDi”)

The breakthrough in engine design achieved by Orbital is a stratified combustion process, which involves an air-assisted injection of fuel directly into the combustion chamber and uses electronic control of the fuel delivery, injection timing, ignition and other variables. The FlexDi combustion process and control is suitable for both two-stroke and four-stroke engines and has been applied successfully across a range of cylinder displacements from 50cc to greater than 500cc, including high operating engine speeds.

In a conventional engine, the fresh fuel/air mixture is prepared upstream of the cylinder (whether by carburettor or conventional EFI) and enters the cylinder during the intake stroke, with the intent of forming a homogenous mixture of air and fuel within the cylinder. The FlexDi systems allow a highly stratified combustion process to occur, containing the combustible fuel cloud to a small area within the cylinder, with the remainder of the air in the cylinder being not fuelled. This process, at light loads, allows the engines with FlexDi Technology to run very lean (in some cases, total engine operation is carried out without the use of an air intake throttle). Under high load conditions, the FlexDi system tends to run more like a homogeneously charged engine, with good mixing of the fuel/air mixtures within the cylinder.

In the case of a two-stroke engine, the FlexDi system allows injection to occur after exhaust port closures at light loads, minimising the short-circuiting of fresh fuel/air mixture out of the exhaust port as occurs in conventional two-stroke engines. In the case of a four-stroke engine, this allows lean engine operation, significantly reducing the engine pumping work.

The combustion process itself, due to control of the air to fuel ratio gradient within the spray plume, allows clean and controlled combustion, resulting in further improvements in fuel economy and emissions control.

Apart from the basic combustion process and the associated fuel and control system, Orbital has developed other technologies including catalyst systems, control systems, control hardware and control software for vehicle applications of engines using the FlexDi Technologies.

Sources of Revenue

Orbital’s primary sources of revenue are currently from:

• provision of consulting and engineering services;

• sale of goods; and

• licence fee income and royalties.

Further details on segment revenue are contained in note 6 of the Consolidated Financial Statements on page F-29.

During the last three fiscal years Orbital spent approximately A$4.120 million on research and development programs. The Orbital group’s licence fee income and royalties relate to the sale of rights to its intellectual property, such as patents and know-how, to major vehicle, engine and component manufacturers through licence and consulting service agreements. These agreements grant the licensee limited rights to manufacture, use and sell products utilising FlexDi Technology.

As at September 30, 2011, Orbital has 17 agreements to end users of technology or suppliers, which grant licence rights related to FlexDi Technology. Orbital’s customer base covers applications in the automotive, marine, recreational and motorcycle markets.

At September 30, 2011 Orbital had seven customers (2010: nine customers) using FlexDi Technology in commercial production.

- 12 -

At September 30, 2011 the following agreements granting rights to Orbital’s FlexDi Technology were in place:

Agreements for Rights to FlexDi Technology

February 2006	Polaris Industries Inc.	Marine & Recreational
September 2006	Bajaj Auto Limited	Auto-rickshaws (gaseous)
September 2007	EGEN srl	Generator Sets

Although these licence agreements differ in their specific terms, generally each licence agreement defines the scope of access rights to the FlexDi Technology, including geographic regions, applications covered by the licence agreement (for example, engine types and horsepower range), any areas of exclusivity which may have been granted, the duration of the licence and royalty periods, and confidentiality provisions. The licence agreements also set out the basis on which initial and ongoing technical disclosure is to be made between the parties and the details of technical programs to utilise the FlexDi Technology, such as performance targets and the quantities of vehicles and engines required to be produced by Orbital for testing purposes by the licensees. A licence agreement also typically covers the licensee’s right to Orbital’s improvements and Orbital’s rights to the licensee’s improvements on the basic FlexDi Technology, as well as indemnity provisions relating to losses arising from products designed and manufactured by Orbital or its licensees. Under the terms of the licence agreements, licensees are not specifically obliged to commence production and sale of engines using FlexDi Technology and may terminate the agreements upon notice to Orbital. If a licensee were to terminate its licence agreement with Orbital, the licensee would forfeit the licence and any technical disclosure fees paid through to the date of termination.

- 13 -

The licence agreements may provide for the payment to Orbital of fees upon the execution of the licence agreement. These initial licence fees may be negligible in some instances and significantly larger in others. Additional fees may also be required after a fixed time interval or after delivery of prototype engines and/or hardware employing the FlexDi Technology that meets specified performance targets, provided the licence agreements are not terminated. In some cases the licence agreements provide for technical disclosure fees and territory fees that are payable upon disclosure and transfer of Orbital’s technical know-how or upon any expansion of the licensees’ rights to FlexDi Technology.

Generally, under the terms of Orbital’s licence agreements, royalty payments will become payable if licensees commence commercial production and sale of engines or components incorporating the FlexDi Technology. Such royalties will usually be based on several factors, which may include a base amount, the engine’s particular horsepower rating, an adjustment for inflation, the benefit delivered to the Original Equipment Manufacturer, access to improvements and the level of technology applied. Royalties currently achieved for the non-automotive application of FlexDi Technology range from approximately US$6.00 for a small scooter to US$69.00 for a large multi-cylinder marine outboard engine.

Commercial production or sale of engines with FlexDi Technology commenced in 1996. Production royalties of approximately A$1.08 million were received by Orbital in the 2011 fiscal year compared to approximately A$1.19 million in fiscal 2010. There can be no assurance that Orbital will be successful in entering into additional licence agreements, that other licensees will commence commercial manufacture of products incorporating the FlexDi Technology, or that Orbital will receive additional fees under existing agreements. Orbital’s financial results have varied from period to period in the past and will continue to experience such fluctuations in the future. There can also be no assurance that products incorporating FlexDi Technology will achieve market success.

Strategic Alliances

Continental

In June 1997, Orbital formed a joint venture company, Synerject, LLC, with Continental Corporation (previously Siemens Automotive Corporation - Continental Corporation acquired Siemens Automotive Corporation in January 2008). At the time of formation, Synerject’s principal activities were to design, develop, manufacture, distribute and sell fuel rail assemblies incorporating FlexDi Technology.

In November 1998, Orbital announced the expansion of the operations of the Synerject joint venture to allow Synerject to provide motorcycle and scooter Original Equipment Manufacturers (“OEMs”) with both air assisted direct injection and electronic fuel injection systems. This includes engine management systems and all peripheral components, and system integration services, in addition to supply of the fuel rail assembly. This expansion enables Synerject to provide both technical and program management services to the customer. Fiscal 2000 saw the launch of the Aprilia SR 50 DITECH (DI Technology), the first commercial motorcycle or scooter using Orbital’s DI Technology, followed by Aprilia’s Scarabeo DITECH™ scooter in 2001. In May 2002, Piaggio, manufacturer of the Vespa brand scooter, and Peugeot Motocycles each launched two motor scooter models incorporating Orbital’s direct injection technology. Peugeot launched its Jetforce scooter during the 2003 fiscal year and Kymco launched its 100cc KDI 2-stroke scooter in the 2005 fiscal year. In May 2007 Bajaj Auto Ltd commenced production in India of an autorickshaw utilising Orbital’s direct injection technology.

During 1998 Orbital’s relationship with Continental was expanded to create an alliance that facilitates the supply of complete integrated systems incorporating FlexDi Technology to automotive customers. This capability is attractive in order to penetrate the automotive industry, as manufacturers are continuing to reduce the number of suppliers and rely more heavily on large companies that act as systems integrators. These system integrators source, validate, and coordinate the supply of the components of a system which may include the fuel rail assembly, electronic control unit, compressor, fuel pump and wiring harnesses. The system is then sold to the manufacturer as a complete unit.

Synerject LLC was restructured and refinanced during fiscal year 2003. In January 2003, new financing arrangements were put in place for Synerject LLC until September 30, 2006. As part of the restructure, in April 2003, Synerject LLC acquired, by way of capital contributions from each joint venturer, the operations of Orbital’s marine and recreation system sales business and Continental’s non-automotive systems business. The actual performance of each of these contributed businesses in the 3 year period to June 30, 2006, compared to the planned performances, was reviewed to determine the optional adjustment to the percentage shareholdings of Orbital and Continental in Synerject LLC (“the recalculation”).

The change in shareholdings as a result of the above recalculation was 10%, i.e., ownership percentages of 40:60.

- 14 -

There was an option for the joint venturer who had the majority shareholding as determined by the recalculation above, to call from the other shareholder (“minority shareholder”) the percentage of shares determined by the recalculation. The minority shareholder may dilute their shareholding or may choose to exercise an option to maintain the 50:50 ownership structure by either paying the other joint venturer US$400,000 for each 1% interest of Synerject or by injecting additional capital into Synerject LLC of US$800,000 for each 1% interest in Synerject.

Continental exercised its option to call from Orbital 10% of the shares in Synerject LLC on March 31, 2009. On that date Orbital exercised its option to maintain the 50:50 ownership amounting to US$4,000,000. Orbital also agreed on March 31, 2009 to sell 8% of Synerject to Continental for US$4,000,000.

Following the sale of the interest the ownership percentages are Orbital 42%:Continental 58%. As a result of the change in ownership Orbital now recognises and discloses its investment in Synerject as an investment in associate.

Orbital and Continental also executed a new shareholders’ agreement that provides for Orbital representation on the board of Synerject and commits both parties to manage the business for the benefit of all shareholders.

Under the terms of the shareholders agreement, the net income and losses of the joint venture are allocated in accordance with the percentage interest held.

In March 2006 Synerject acquired a business based in Delavan, Wisconsin, which supplies fuel systems and components for outboard marine engines from BRP US Inc for approximately US$2.5 million. The investment by Synerject consisted of working capital, principally inventory and plant & equipment.

During fiscal year 2007 Synerject established a manufacturing facility in Changchun, China and an engineering support facility in Chongqing, China. These facilities have been established to produce low cost electronic control units for motorcycle applications, with manufacturing commencing in fiscal year 2008.

Synerject has expanded to other non-automotive small gasoline engine applications such as those of the lawn and garden and industrial markets.

Synerject has operations located in Newport News, Virginia, Delavan, Wisconsin, Toulouse, France and Changchun and Chongqing, China (as noted above). In Newport News, Synerject manufactures air injectors and fuel rail assemblies for the majority of Orbital’s marine and motorcycle customers and supplies systems to marine customers. In Delavan, Synerject manufactures electronic management modules and direct injection fuel injectors and oil pump assemblies primarily for Bombardier Recreational Products. In Toulouse, Synerject sources components (including air injectors and fuel rail assemblies manufactured in Newport News) and supplies systems to motorcycle customers. As noted below, in April 2003, Synerject acquired Continental’s non-automotive systems business which is now conducted in Toulouse.

UCAL Fuel Systems

In February 2003, Orbital entered into a Technical Cooperation Agreement with UCAL Fuel Systems Ltd, a manufacturer of carburettors and fuel injection system components for the Indian motorcycle and automotive markets. Under the agreement, UCAL has been granted the right to manufacture and supply components of Orbital’s direct injection fuel systems to the 2-stroke 2 and 3 wheeler motor vehicle market in India.

Vialle

In June 2008, in parallel with the acquisition of Boral Alternative Fuel Systems (now Orbital Autogas Systems), Orbital entered into Licencing Agreements with Vialle for the distribution of LPG fuel systems in Australia and New Zealand. The Licence Agreements cover the sale of vapouriser LPG fuel systems and Liquid LPG fuel systems.

Motonic Corporation

In September 2009, Orbital reached an agreement with Motonic Corporation of Korea for the exclusive access to Motonic products for the Australian LPG Autogas market.

Motonic is the world’s largest supplier of LPG Autogas components. Motonic is a Tier 1 supplier of LPG Autogas systems to Hyundai, the world’s largest manufacturer of LPG vehicles.

- 15 -

Competition

Orbital’s success depends upon its ability to continue to earn revenue from consulting services, to maintain a competitive position in the development of FlexDi^TM Technology in relation to other existing and emerging technologies and to increase market share in the Australian LPG market by sale of its newly developed Liquid LPG fuel system.

Success of the FlexDi^TM Technology is also dependent upon Orbital’s ability to both displace current fuel injection and combustion technologies for four-stroke or two-stroke internal combustion engines, which have an established and dominant position in this field, and its ability to gain market share against emerging technologies. There is significant competition from automobile and engine manufacturers and consulting firms specialising in the development of internal combustion engine technology for the automotive, marine, motorcycle and small engine industry. These companies may have substantially greater resources for research, development and manufacturing than Orbital. Despite the fact that Orbital has developed, patented and licensed the FlexDi^TM Technology to a number of automobile and engine manufacturers, it is possible that Orbital’s competitors may succeed in developing alternative technologies and products that are more effective or commercially more acceptable than those developed by Orbital.

There is a difference between an individual engine design and the broad range of possibilities covered by the FlexDi^TM Technology for which fees are charged under licensing agreements. Manufacturers may have their own specific engine designs incorporating FlexDi^TM Technology as well as their own proprietary and non-proprietary know-how. Licensees may market the individual characteristics of their engine designs without reference to the fact that the FlexDi^TM Technology is required or being used. Under the terms of Orbital’s licence agreements, royalties would be payable in such situations.

Other competition to engines employing FlexDi^TM Technology may also include other lean burn engines, electro-magnetic valve lift and timing actuation, electric motors, hybrid vehicles and fuel cells and other concepts not known to Orbital. Insofar as these technologies incorporate efficient technology for internal combustion engines they would be complementary to FlexDi^TM Technology, for instance in hybrid vehicles.

Current four-stroke technology also remains the main competitor to the introduction of FlexDi^TM Technology for non-automotive applications. Various direct injection technologies, such as high pressure, single fluid direct injection systems, are available to engine manufacturers to improve the performance of two-stroke engines as an alternative to both the current four-stroke and FlexDi^TM Technology.

With respect to provision of consulting services, Orbital competes against consulting groups such as Ricardo, AVL, FEV and others, which have well established European presences and growing presences in the China/Asia market. An additional competitor to Orbital’s services is the customer’s internal resources. In all cases, Orbital must compete on work-scope, cost and quality with its competitors. Orbital’s competitors may have significantly more financing available than Orbital which may help to win certain work programs. The consulting service requirement is directly influenced by global, national and OEM company financial positions and also by the presence, or lack of, drivers such as new emission or other regulatory changes.

Synerject, as an Engine Management System and component supplier for the non-automotive market for both direct injection and manifold port injection, and for Orbital’s proprietary air injector for the automotive market, competes directly with established suppliers such as Bosch, Del’orto, Magneti Marelli, Delphi and others.

Orbital’s competitors in the Australian LPG market include Apollogas, Boemo Engineering and Impco.

Alternative Fuels

Alternative fuel system development is core to Orbital’s growth strategy. Long term projections for increased crude oil prices, together with sovereign fuel security and requirements to reduce vehicle emissions, drive this strategy. The U.S. government has announced major developments and sponsorship for use of CNG (Compressed Natural Gas). In the Asia Pacific region, the size of the CNG vehicle fleet increased by almost 16% to 6.7 million vehicle, with a global increase of 11%. In Europe there is a push for increasing use of CNG and LPG (Liquid Petroleum Gas) with European Automotive manufacturer’s now offering product using both of these fuels. In the LNG (Liquid Natural Gas) application the “Blue Corridor” (key road transport routes with LNG readily available) is being developed in continental Europe. Orbital is already active in this space and plans to grow in each of these markets.

Revenue decreased by approximately 6% compared to last year due to Ford ceasing production of the previous generation LPG Falcon at the end of September 2010. Revenue was partly compensated by increased aftermarket sales including contribution from Sprint Gas Australia (SGA) which was acquired at the end of May 2011. Gross margins improved due to the stronger Australian dollar compared to the Euro. Operational efficiencies have also been introduced reducing overheads resulting in an overall year on year improvement in contribution of $970,000, before impairment allowance.

During the fiscal year 2011 the Orbital Autogas Systems operation was reviewed. The contraction in the LPG aftermarket prompted a write-down of previously capitalised development costs for Liquid LPi aftermarket kits ($1,065,000). In addition it was decided to provide for slow moving Liquid LPi aftermarket inventory ($942,000). In total these non-cash adjustments amounted to $2,007,000.

Ford Australia has recently released their “EcoLPi” Ford Falcon vehicle range equipped with Orbital’s Liquid LPG systems (Liquid LPi). The response from the motoring press has been very positive. Liquid LPi technology solves issues of emissions compliance, cold start and reduced power compared with previous LPG systems. Most importantly, fuel cost savings are approximately $1,000 per year based on current fuel costs for a typical Australian family vehicle.

Orbital’s Liquid LPi systems were also introduced on Holden Special Vehicles in late 2010, confirming that the systems can meet the needs of Australia’s most prestigious and highest performance cars.

In May 2011, Orbital acquired the business of SGA for an initial investment of $2,000,000. SGA is a major LPG distributor in Victoria, with a presence in most capital cities in Australia. SGA offers a full range of LPG systems for the aftermarket, and will be an outlet for Orbital’s Liquid LPi systems. SGA also enables an Orbital presence in Victoria which is the centre of Australia’s auto LPG markets and the home of Australia’s automotive manufacturing businesses.

Orbital strategically invested in the LPG aftermarket at a time when the Australian market was under pressure. The Australian LPG aftermarket contracted throughout the year (approximately 50%), driven initially by the relatively lower differential between the cost of petrol and LPG, and reduction in the Australian federal government installation subsidy. However, LPG continues to offer a lower cost, cleaner alternative to petrol. We acquired a company that has a lead market share position in Australia. Orbital’s initial investment is effectively net asset value and we retain the support of the long standing owners. This positions Orbital for future recovery in LPG markets.

Looking forward, Orbital is undertaking research and development in the next generation of alternative fuels systems; for example direct injection of alternative fuels. In the case of CNG, direct injection can reclaim some of the performance typically lost with manifold injection applications of CNG. Orbital continues to support direct injection CNG projects for international customers.

Synerject

Synerject, Orbital’s 42:58% Joint Venture Partnership with Continental AG, is a key supplier of engine management systems to the non-automotive market, with small engine applications for scooters through to high performance motorcycles, outboards and snowmobiles.

Synerject’s revenue increased by 36% to US$121,673,000 with a corresponding increase in profit after tax.

The marine and recreational markets are still impacted by the ongoing effect of the global financial crisis. However Synerject achieved growth with investment in new products which have been launched throughout the year. In particular, Synerject has expanded in the supply of systems to the high end market including snowmobiles and high performance motorcycles.

Taiwan, with its stringent in-field emission requirements remains a major market for Synerject, with two out of the three major Taiwanese motorcycle/scooter manufactures utilizing Synerject product. China is the largest motorcycle market in the world and has recently introduced motorcycle Euro III emissions standards. This remains Synerject’s primary growth target.

Synerject has also recently introduced new products into the high volume utility and small engine markets.

Notwithstanding the revenue growth Synerject kept tight control of working capital, generating increased cash flow year on year. Synerject had net cash on hand at June 30, 2011 of US$2,291,000 (2010: US$3,316,000 net debt). Orbital received dividends of A$1,208,000 from Synerject during the year (2010: A$677,000).

The Australian dollar has strengthened against the US dollar over recent years adversely impacting the translated equity accounted share of Synerject’s profit (FY2011: A$416,000 impact).

Synerject is well positioned in all of its markets and has a number of new product launches planned in the next 12 months. Synerject has a strong balance sheet and the active support of both Orbital and Continental AG.

Consulting Services

Orbital Consulting Services (OCS) provides engineering consulting services, design, development and testing in the areas of engine design, engine combustion, fuel systems, engine management systems, alternative fuels, engine and vehicle testing and certification. Orbital provides fuel economy and emissions solutions to a wide variety of vehicle applications, from small displacement utility engines to large transportation and power generation applications.

OCS revenue of $9,492,000 in FY2011 was marginally lower than FY2010. A significant portion of OCS customers are overseas and the strong Australian dollar has meant that OCS services are less competitive globally and margins are under pressure. Orbital continues to win new programs on a consistent basis due to the unique technology and services offered by Orbital, and the order book is higher now than this time last year.

Orbital’s new dual fuel LNG system development continues working with Western Australia’s Mitchell Corporation (recently acquired by Toll Transport). The initial pilot level fleet of three LNG system fitted prime movers has expanded to nine. Mitchell has achieved significant fuel cost savings compared to diesel fuel only operation and improved reliability. Orbital’s success with the Mitchell LNG program has generated interest from the broader transport industry. To expand significantly in this segment will require industry buy-in, expanded fuelling infrastructure and additional investment. We see this as a growth area; however we will continue to have a measured approach to limit Orbital’s future financial exposure without limiting the upside in LNG for transport.

Major work for OCS is the development of spark ignition heavy fuel engines for UAS (unmanned aerial systems) applications. Orbital’s proprietary FlexDI^TM systems enable a petrol type engine to run on heavy fuels and continue to deliver high performance. Orbital goes beyond FlexDI^TM offering engine design, development and prototype engine systems for various customer applications. We anticipate that this segment of our business will grow and strategically it is complementary to Orbital’s alternative fuels initiative.

The Changan program has been successfully completed, confirming the capability of the Orbital FlexDI^TM fuel system, which was integrated into Changan’s new Intelligent Compound Combustion system (ICCS). Orbital and Changan hit the target of 20% reduction for vehicle fuel consumption as measured on the European Drive Cycle. The improved performance of the engine was also demonstrated in the vehicle assessment. Changan are satisfied with the results and displayed the engine concept at the Shanghai Auto show in April 2011.

Orbital’s heavy duty engine test cell continues to be in high demand, with the test facility working extended hours during the year to match customer demand plus supporting Orbital’s large engine R&D. The heavy duty test facility has proven to be a worthwhile investment.

Orbital’s core consulting group provides consulting fee for services to external customers and creates new products for the Orbital group. The support ranges from advanced engine R&D through to development of LPG aftermarket kits and support for customer application programs.

At July 31, 2011 Orbital had an order book of $4,630,000 (June 30, 2010: $3,400,000)

Licences and Royalties

Orbital earns royalties and licenses from production using its FlexDI^TM systems and technology. The royalty bearing products today are in the recreational and scooter/motorcycle markets.

Orbital’s key royalty earning products, the Mercury Marine Optimax and the Tohatsu TLDI, achieved a slight increase in volume in a relatively flat global outboard engine market. As Orbital’s royalties are predominantly earned in US Dollars, the volume increase was, however, offset by the strength of the Australian Dollar.

The recreational market growth is expected to remain flat, especially in the key North American market, due to financial insecurity and the general careful use of discretionary income.

Orbital Research and Development

Orbital’s R&D, aligned with the growing importance of alternative fuels and energy management, are central to Orbital’s activities aimed at positioning the company as a leading edge technology company with the ability to provide solutions to Original Equipment Manufacturers and industry.

Orbital’s primary focus this year was on development and implementation of automotive LPG systems, development of advanced Direct Injection and powertrain systems for 4 stroke automotive engines and in development of systems for spark ignition heavy fuel engines.

The continued commitment to the core R&D has resulted in two new patents granted in the last 12 months, along with eight new patent family applications strengthening the Orbital patent portfolio and extending the life of royalty streams.

Patent Protection

Orbital continues to actively investigate new technologies while also seeking to improve and enhance existing technology through continued research and development and product development, particularly in regard to FlexDi^TM and alternative fuel systems related technology. Orbital believes that patent protection of its technologies and processes is critical to its future financial performance and that its success depends upon its ability to protect its proprietary products and technology under applicable intellectual property laws. Accordingly, Orbital has been, and intends to continue to be, active in securing and policing intellectual property rights for its proprietary products and technology.

As at September 30, 2011, Orbital had 64 individual patent families with a total of over 155 patents and patent applications around the world. As of September 30, 2011 there were 34 granted patents and nine patent applications pending in the United States (including PCT patent applications). There are numerous other developments for which patent protection has not been obtained and these form part of Orbital’s proprietary know-how. Trade secrets and confidential know-how are protected through confidentiality agreements, contractual provisions and administrative procedures. There can be no assurance that such arrangements will provide meaningful protection for Orbital in the event of any unauthorised use or disclosures.

Orbital is not a party to any present litigation relating to patents, but it has in the past and may in the future receive claims from other parties that the FlexDi^TM engines or components or elements of such engines infringe patent rights or other rights of such other parties. Orbital may also in the future need to sue other parties for infringement of patent or other intellectual property rights relating to its FlexDi^TM Technology. In the event of either being sued by other parties or suing other parties, the management time and legal expenses required to be devoted to these claims could have an adverse effect on Orbital’s future operating results, even if Orbital won any such suits.

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

General

During the 2011 fiscal year Orbital’s revenues were generated from contracts for consulting services, including engine development programs, sale of goods and licensing and licensing related agreements for FlexDi^TM Technology. In addition, Orbital equity accounted its share in Synerject LLC’s result.

Unless otherwise indicated, all financial information in the following discussion is derived from Orbital’s Consolidated Financial Statements, included herein, prepared in accordance with International Financial Reporting Standards.

Critical Accounting Policies and Estimates

Orbital’s Consolidated Financial Statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”), as issued by the International Accounting Standards Board.

Our significant accounting policies are more fully described in Note 3 to our consolidated financial statements. The preparation of our consolidated financial statements requires management to make estimates and judgements that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent liabilities. We continually evaluate our estimates and judgements including those related to product warranties, trade debtors and deferred taxation. We base our estimates and judgements on historical experience and on various other assumptions we believe to be reasonable under the circumstances. This forms the basis for making judgements about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions.

In developing accounting policies, in addition to IFRS requirements, we also consider industry practice.

The critical accounting policies discussed below are applied consistently to all segments of Orbital. Management has discussed the development and selection of these critical accounting policies with the Audit Committee of our Board of Directors.

The financial statements of the equity accounted associate, Synerject LLC, are prepared under US GAAP and adjusted to reflect consistent accounting policies with Orbital.

The following are the critical accounting policies and estimates that have been adopted in preparing our IFRS financial statements:

Long term borrowings

Included in non-current liabilities is an amount owing to the Government of Western Australia resulting from a loan of $14,346,164 restructured in January 2010. The loan is interest-free with annual repayments commencing in May 2010 and concluding in May 2025.

The non-interest bearing loan from the Government of Western Australia was recognised initially at fair value and subsequently stated at amortised cost using the effective interest method. The difference between the fair value and face value of the loan is accounted for as a government grant as disclosed in note 26.

Equity Accounting

The consolidated financial statements include the consolidated entity’s share of the total recognised gains and losses of an associate on an equity accounted basis. For a number of years, the consolidated entity’s share of losses exceeded its interest in the associate, and during that period, the consolidated entity’s carrying amount was reduced to nil and recognition of further losses continued to the extent that the consolidated entity had incurred legal or constructive obligations on behalf of the associate.

Consolidation of Sprint Gas (Aust) Pty Ltd

On 27 May 2011, Orbital Autogas Systems Pty Ltd acquired 55% of the voting shares of Sprint Gas (Aust) Pty Ltd, a new company incorporated to acquire the operating business of Sprint Gas, an Australian business specializing in the importation and wholesaling of LPG Fuel systems. Concurrently with the entering into of the Business Acquisition Agreement, the Group entered into a Subscription and Shareholders Agreement with the owners of the 45% non-controlling interest in Sprint Gas (Aust) Pty Ltd. As part of the Subscription and Shareholders Agreement Call and Put options were issued over the remaining 45% non-controlling interest. Management has determined that the Call and Put options, exercisable after 30 months, are in nature a forward contract and in substance represent contingent consideration. The Group has accounted for the business combination as though it acquired a 100% interest and has recognised a financial liability to the non-controlling shareholders equal to the fair value of the underlying obligations under the Put and Call option (Contingent consideration liability).

- 21 -

Research and Development Expenditure

Expenditure on research activities, undertaken with the prospect of gaining new scientific or technical knowledge and understanding, is recognised in the income statement as an expense as incurred.

Expenditure on development activities, whereby research findings are applied to a plan or design for the production of new or substantially improved products and processes, is capitalised if the product or process is technically and commercially feasible and the consolidated entity has sufficient resources to complete development. Orbital’s share of development expenditure capitalised (included in results of jointly controlled entity) in fiscal 2011 is $0.580 million (2010 $0.274 million, 2009 $0.297 million).

Capitalised expenditure on development activities relating to the next generation Liquid LPG fuel systems was $0.594 million in Fiscal 2011 (2010: $1.128 million).

Patents, Licences and Technologies

Patents, licences and technology development and maintenance costs are expensed as incurred.

Expenditure capitalised and amortisation

Expenditure on intangible assets which are capitalised includes the cost of materials, direct labour and an appropriate proportion of overheads. Other development expenditure is recognised in the income statement as an expense as incurred. Capitalised expenditure is stated at cost less accumulated amortisation and impairment losses. Amortisation will be charged to the income statement on a straight-line basis over the estimated useful lives of intangible assets unless such lives are indefinite.

Impairment

The carrying amount of all assets is reviewed at each reporting date to determine whether there is any indication of impairment. If any such indication exists, the asset’s recoverable amount is estimated. The recoverable amount is the greater of the asset’s fair value less costs to sell and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. In relation to goodwill, impairment is determined by assessing the recoverable amount of the cash-generating unit (group of cash-generating units), to which the goodwill relates.

Allowance for impairment loss of Trade Debtors

Allowance for impairment loss of trade debtors is estimated based on an analysis of trade debtors exceeding agreed payment terms and the likelihood of collection having regard to recent payment histories, subsequent cash receipts and direct correspondence with the relevant customers. We believe that we adequately manage our credit risk through our evaluation process, credit policies and credit control and collection procedures. However, losses on amounts receivable from our largest customers could be material to our results of operations. Allowance for impairment loss amounted to A$0.154 million at June 30, 2011 (A$0.116 million at June 30, 2010), with a bad debts write-off for the year of A$0.005 million (2010: A$Nil).

Refer to “Results of Operations Fiscal 2011 Compared with Fiscal 2010” below for further explanation of the above expenses.

Income Tax

(i) Current income tax expense and liability

Income tax on the income statement for the year presented comprises current and deferred tax. Income tax is recognised in the income statement except to the extent that it relates to items recognised directly in equity, in which case it is recognised in equity.

Current tax is the expected tax payable on the taxable income for the year, using tax rates enacted or substantively enacted at the reporting date, and any adjustment to tax payable in respect of previous years.

- 22 -

(ii) Deferred income tax expense and liability

Deferred tax is provided using the liability method, providing for temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. The amount of deferred tax provided is based on the expected manner of realisation or settlement of the carrying amount of assets and liabilities, using tax rates enacted or substantively enacted at the reporting date.

A deferred tax asset is recognised only to the extent that it is probable that future taxable profits will be available against which the asset can be utilised. Deferred tax assets are reduced to the extent that it is no longer probable that the related tax benefit will be realised.

(iii) Tax Consolidation

The Company and its wholly-owned Australian resident entities have formed a tax-consolidated group with effect from 1 July 2002 and are therefore taxed as a single entity from that date. The head entity within the tax-consolidated group is Orbital Corporation Limited.

The head entity and the controlled entities in the tax consolidated group continue to account for their own current and deferred tax amounts. The Group has applied the group allocation approach in determining the appropriate amount of current taxes and deferred taxes to allocate to members of the tax consolidated group.

Any current tax liabilities (or assets) and deferred tax assets arising from unused tax losses of the subsidiaries is assumed by the head entity in the tax-consolidated group and are recognised as amounts payable (receivable) to (from) other entities in the tax-consolidated group in conjunction with any tax funding arrangement amounts. Any difference between these amounts is recognised by the Company as an equity contribution or distribution.

The Company recognises deferred tax assets arising from unused tax losses of the tax-consolidated group to the extent that it is probable that future taxable profits of the tax-consolidated group will be available against which the asset can be utilised.

Any subsequent period adjustments to deferred tax assets arising from unused tax losses as a result of revised assessments of the probability of recoverability is recognised by the head entity only.

Deferred taxation

We recognise a deferred tax asset in our statement of financial position only where we determine that it is probable that it will be recovered. A portion of the deferred tax asset recorded in our statement of financial position relates to current or prior period tax losses where management considers that it is more likely than not that we will recover the benefit of those tax losses in future periods through the generation of sufficient future taxable profits. Our assumptions in relation to the generation of sufficient future taxable profits depend on our estimates of future taxable profits, which are estimated based on forecasts of consulting services income, licence and royalty receipts and Synerject’s business plans. These estimates are subject to risk and uncertainty, hence there is a possibility that changes in circumstances will alter the projections, which may impact the recoverability of the deferred tax asset recorded in our statement of financial position and those tax losses currently provided as not recoverable. In such circumstances, some or all of the carrying value of the deferred tax asset may require provisioning and we would charge the expense to the profit and loss account, and conversely, some or all of the amounts provided as not recoverable may be reversed and we would credit the benefit to the income statement.

At June 30, 2011, our deferred tax asset included A$4.716 million (A$5.215 million at June 30, 2010), in relation to prior period tax losses.

Temporary differences

Temporary taxation differences, arising due to timing differences between the periods in which transactions are recognised for accounting purposes differing to the periods in which those transactions are recognised for income taxation purposes, of the Company and its Australian resident controlled entities, increased during fiscal 2011 by A$0.440 million to A$2.167 million at June 30, 2011 from A$1.727 million at June 30, 2010. A$1.934 million of the temporary difference relates to a provision for capital loss on an investment.

- 23 -

Carry forward tax losses

Australia

Tax carry forward losses of the Company and its Australian resident controlled entities increased during fiscal 2011 by A$0.843 million to A$59.690 million at June 30, 2011 from A$58.847 million at June 30, 2010.

Australian income tax carry forward losses do not expire and can be carried forward indefinitely subject to:

i) the Company and/or its controlled entities continuing to comply with the conditions for deductibility imposed by the law;

ii) the companies being able to satisfy the tests as set out in the taxation consolidations legislation enacted in Australia, which provides further tests in relation to transferring losses to a consolidated group and recouping losses within the group; and

iii) no changes in tax legislation adversely affecting the relevant company and/or the consolidated entity in realizing the benefit.

Potential future income tax benefits in Australia have not been recognised as assets at June 30, 2011 because it is not probable that future profits will be available against which the consolidated entity can utilise the losses and timing differences.

For the consolidated entity to fully realize its potential Australian future income tax benefits it will need to generate future Australian taxable income of approximately A$59.690 million and be in a position to utilize the taxable income against the benefits in the Company and the controlled entities retaining those benefits in accordance with the consolidations legislation.

United States of America

At June 30, 2011, tax carry forward losses of approximately A$37.391 million (US$40.154 million) (2010: A$57.594 million (US$45.035 million)) are available to certain controlled entities in the United States. A deferred tax asset of A$4.716 million (US$5.064 million) (2010: A$5.215 million (US$4.493 million)) has been recognized as an asset as it is probable that future profits will be available against which the consolidated entity can utilise the losses.

Under the tax laws of the United States, tax losses that cannot be fully utilized for tax purposes during the current year may, subject to some statutory limitations, be carried forward to reduce taxable income in future years. At June 30, 2011, the US$40.154 million of tax carry forward losses available expire between the years 2012 and 2024.

For the controlled entities in the United States to realize their potential United States future income tax benefits they will need to generate future taxable income of approximately US$40.154 million. Approximately US$5.014 million of taxable income will be required in fiscal 2012 when the next portion of the benefit is due to expire.

Based upon the level of historical taxable income and current projections for future taxable income over the periods in which the tax carry forward losses are deductible in both Australia and the United States, management are only in a position to state that it is probable that benefits totalling A$4.716 million in respect of carry forward losses will be realised in full.

The deferred tax asset recognised as at June 30 each year represents management’s assessment of the amount of carry forward losses that it is probable will be deductable in the following five years. The movement in the recognised deferred tax asset from June 30, 2010 to June 30, 2011 is the result of the movement of the assessment period and also updates to future forecast results.

Results of Operations Fiscal 2011 Compared with Fiscal 2010

Orbital’s net profit after tax was A$1.763 million for the year ended June 30, 2011 compared to a net profit of A$4.516 million for the year ended June 30, 2010.

Revenue from trading activities in fiscal 2011 decreased as compared to fiscal 2010 by 3.6% to A$16.638 million:

• Consulting services income decreased 1% (A$0.129 million) to A$9.492 million, reflecting a steady workload from key contracts. Significant programs during the year included the development of a powertrain fuel economy demonstrator for China, development of the next generation Liquid LPG fuel system for Ford Australia’s EcoLPi Falcon and the development of spark ignited heavy fuel engines for unmanned aerial systems.

• Sale of goods decreased 6% to A$5.847 million due to Ford ceasing production of the previous generation LPG Falcon at the end of September 2010 and reflecting a challenging LPG retrofit market.

- 24 -

• Licence and Royalty income decreased by 10% to A$1.081 million due to the impact of the stronger Australian dollar and steady royalty volumes.

• Sprint Gas revenues of A$1.112 million were included in Orbital’s results for the first time in the year ended June 30, 2011, following its acquisition in May 2011.

Other income, excluding the gain on the sale of the property in 2011 of A$4.237 million and the government grant arising on restructure of non interest bearing loan of A$7.695 million in 2010, improved by A$0.809 million compared to fiscal 2010.

In February 2011 Orbital completed the sale and leaseback of its land and buildings in Perth for A$8.650 million. The sale generated a net profit of approximately A$4.237 million.

Total costs and expenses (excluding share of net profit of equity accounted investee, Synerject LLC) increased 4.0% to A$19.924 million in fiscal 2011 from A$19.163 million in fiscal 2010. The net increase was due to the following:

• Total employee expenses decreased by 2.8% to A$10.494 million as a result of the reversal of the medium term incentive bonus accrued in fiscal 2010 and a decrease in headcount.

• Depreciation and amortisation increased by 16.9% to A$1.174 million primarily due to the amortisation of capitalised development expenditures.

• Engineering consumables and contractor expenses decreased by 6.3% to A$1.954 million reflecting a different mix of consulting activity.

• Occupancy expenses increased by 48.2% to A$1.165 million as a result of the sale and lease-back of the Balcatta premises.

• Travel and accommodation expenses decreased by 26.8% to A$0.634 million as a result of decreased overseas travel.

• Communication and computing expenses decreased by 25.0% to A$0.593 million reflecting cost saving initiatives introduced during the fiscal year.

• Patent costs decreased by 11.2% to A$0.300 million as a result of the rationalisation of the patent portfolio.

• Audit, compliance and listing costs increased by 25.7% to A$0.704 million as a result of increased share registry costs and the impact of over accruals from prior periods reversed in fiscal 2010.

• Finance costs have decreased by A$0.067 million to A$0.688 million as a result of decreased short term borrowings.

• As a result of the contraction of the LPG aftermarket, it was decided to write down previously capitalised development expenses for Liquid LPi aftermarket kits (A$1.065 million) and provide for slow moving Liquid LPi aftermarket inventory (A$0.942 million).

• Other expenses (excluding the write-off of previously capitalised development expenditure $1.065 million) were steady.

Orbital’s share of Synerject’s net profit increased by 72.5% to A$3.233 million in fiscal 2011 from A$1.874 million in fiscal 2010. Synerject’s revenue increased by 35.9% to US$121.673 million as a result of the introduction of new products, particularly the high end non-automotive markets including snow mobiles and high performance motorcycles. Development expenses of A$0.580 million incurred by Synerject have been capitalised in Orbital’s equity accounted results (fiscal 2010 A$0.274 million) in accordance with IFRS.

The income tax benefit for fiscal 2011 was A$0.190 million, being primarily recognised Deferred Tax Asset (A$0.532 million) offset by State and Federal income taxes in the United States (A$0.342 million) as a result of our share of Synerject taxable income. In fiscal 2010, Orbital recognised A$0.417 million Deferred Tax Asset in the net income tax benefit of A$0.388 million.

Inflation has had a minimal effect on Orbital’s results of operations in fiscal 2011 compared to fiscal 2010

Results of Operations Fiscal 2010 Compared with Fiscal 2009

Orbital’s net profit after tax was A$4.516 million for the year ended June 30, 2010 compared to a net loss of A$2.451 million for the year ended June 30, 2009.

Revenue from trading activities in fiscal 2010 as detailed in Income Statements in the Consolidated Financial Statements increased as compared to fiscal 2009 by 5% to A$17.265 million:

• Consulting services income increased 9% (A$0.823 million) to A$9.621 million, reflecting a steady workload from key contracts. Significant programs during the year included the application of FlexDi^TM to an ethanol fuelled internal combustion engine in Brazil and the development of a powertrain fuel economy demonstrator for China.

- 25 -

• Licence and Royalty income increased by 7% to A$1.199 million due to a 45% increase in royalty volumes, offset by $0.180 million decrease due to the strengthening Australian dollar.

• Sale of goods decreased 1% to A$6.203 million reflecting a tough LPG retrofit market.

Other income, excluding the government grant arising on restructure of non interest bearing loan of A$7.695 million, improved by A$0.372 million compared to fiscal 2009 (A$0.692 million, excluding the gain on sale of interest in Synerject of $3.678 million).

In January 2010 Orbital renegotiated the terms of the A$19.0 million loan from the Western Australian Government due to be repaid in May 2014. The loan was replaced by an interest free A$14.346 million loan repayable over 15 years to 2025. The restructure resulted in a non cash gain of A$7.695 million.

Total costs and expenses (excluding share of net profit of equity accounted investee, Synerject LLC) increased 5.7% to A$19.163 million in fiscal 2010 from A$18.136 million in fiscal 2009. The net increase was due to the following:

• Total employee expenses increased by 9.9% to A$10.792 million as a result of an increase to the headcount of staff in the Orbital Autogas Systems business.

• Depreciation and amortisation decreased by 8% to A$1.004 million primarily due to items reaching full depreciation during the year.

• Engineering consumables and contractor expenses increased by 36% to A$2.085 million reflecting an increased use of external contractors and higher requirement of project consumables during the year reflecting a different mix of consulting activity.

• Travel and accommodation expenses decreased by 27% to A$0.866 million as a result of decreased overseas travel.

• Communication and computing expenses increased by 11% to A$0.791 million reflecting the addition of the new Orbital Autogas Systems business.

• Patent costs decreased by 21% to A$0.338 million from A$0.431 million.

• Insurance, audit, compliance and listing costs decreased by 9% to A$1.001 million from A$1.097 million mainly as a result of reduced compliance requirements for SEC registrants (Sarbanes Oxley section 404), offset by increased insurance costs.

• Finance costs have increased by A$0.029 million to A$0.755 million as a result of increased short term borrowings.

• Other expenses were steady at A$1.531 million.

Orbital’s share of Synerject’s net profit increased by 1% to A$1.874 million in fiscal 2010 from A$1.846 million in fiscal 2009. Synerject’s revenue increased by 20% to US$89.536 million as a result of improvements in the North American marine market, the acquisition of a new business and the introduction of new products. Development expenses of A$0.747 million incurred by Synerject have been capitalised in Orbital’s equity accounted results (fiscal 2009 A$0.297 million) in accordance with IFRS.

The income tax benefit for fiscal 2010 was A$0.388 million, being primarily recognised Deferred Tax Asset (A$0.417 million) and recouped withholding tax (A$0.212 million) offset by State and Federal income taxes in the United States (A$0.231 million) as a result of our share of Synerject taxable income. In fiscal 2009, Orbital de-recognised A$1.731 million Deferred Tax Asset in the net income tax expense of A$2.147 million.

Inflation has had a minimal effect on Orbital’s results of operations in fiscal 2010 compared to fiscal 2009.

Liquidity and Capital Resources

As at June 30, 2011, Orbital’s cash balance, including short term deposits, was A$6.874 million compared to A$3.608 million at June 30, 2010 and A$10.123 million at June 30, 2009. At September 30, 2011 the cash balance was A$6.328 million. In Orbital’s opinion, the working capital is sufficient for its present requirements.

For fiscal 2011 Orbital recorded a net cash outflow from operations of A$1.792 million compared to cash outflows of A$5.049 million in fiscal 2010 and A$2.097 million in fiscal 2009. The cash outflow in fiscal 2011 resulted from cash flow used in operating activities of A$2.041 million and working capital sources of A$0.249 million. This compares with net cash used by operating activities in fiscal 2010 of A$3.611 million (fiscal 2009 of A$6.310 million) plus working capital requirements of A$1.438 million (fiscal 2009: working capital sources A$4.213 million). Synerject’s equity accounted result is non cash and therefore has no impact on operating cash flow in either fiscal 2011 or fiscal 2010 (however Synerject paid dividends to Orbital in Fiscal 2011, Fiscal 2010 and Fiscal 2009, including a special dividend of A$3.151 million in Fiscal 2009).

Research and development expenditures were A$1.158 million in fiscal 2011, A$1.152 million in fiscal 2010 and A$1.810 million in fiscal 2009. Research and development activity during fiscal years 2011, 2010 and 2009 was in developing new technology for advanced combustion systems, combustion of alternative fuels (liquid and gaseous) in internal combustion engines, further developing the air-assist DI system for application on new products, and in development of the next generation LPG fuel systems.

Orbital generated net cash of A$3.477 million from investing activities in fiscal 2011 compared to A$1.699 million in fiscal 2010 compared with A$2.319 million cash outflow in fiscal 2009. In fiscal 2011, Orbital sold its land and buildings in Perth for A$8.650 million (A$8.557 million net of selling costs). In fiscal 2011, Orbital acquired the business of Sprint Gas Australia for an initial investment of A$1.780 million (net of cash acquired). The capital expenditure in fiscal 2011 consisted mainly of the development of the next generation of Liquid LPG fuel systems and tooling costs associated with the Ford EcoLPi Falcon LPG fuel system. No advances to Synerject were required in fiscal 2011, 2010 or 2009. Synerject paid Orbital dividends of A$1.208 million in fiscal 2011 (A$0.677 million in fiscal 2010 and A$4.577 million in fiscal 2009). In fiscal 2011, Orbital acquired a short term deposit of A$3.434 million. In fiscal 2010, Orbital redeemed A$3.500 million short term deposits which were acquired in fiscal 2009.

Orbital has a A$2.500 million Trade Finance facility with Westpac Banking Corporation to provide support for the import of inventory for the Orbital Autogas Systems business. At June 30, 2011, A$0.648 million (fiscal 2010: A$2.056 million, fiscal 2009: A$1.520 million) of the facility had been drawn down.

Orbital had no capital expenditure contracted but not provided for as at June 30, 2011. In July 2008, Orbital received funding of A$2.760 million from the Commonwealth of Australia through the Alternative Fuels Conversion Program administered by the Department of the Environment, Water, Heritage and the Arts towards the construction of a heavy duty engine test facility. The total construction costs were approximately A$3.500 million. Orbital is obliged to fund the maintenance and operation of the facility until at least fiscal 2015 and provide the Commonwealth with preferential access to the facility.

The government grant will be recognised as income over the periods and in the proportions in which depreciation on the heavy duty engine test facility is charged.

Capital Expenditure

The Company has budgeted capital expenditures of A$1.296 million for fiscal year 2012 primarily in the expansion of the Orbital Autogas Systems business and the establishment of new premises for Sprint Gas. Funds for such expenditure will be sourced internally. In the event of a delay or a reduction in capital expenditure during fiscal 2011 the Company would still have sufficient plant, equipment and other facilities to maintain operating levels in line with previous years. There are no long-term capital commitments by the Company.

Orbital’s Jointly Controlled Entity, Synerject LLC

Net cash provided by Synerject’s operating activities in fiscal 2011 was US$9.105 million, fiscal 2010 was US$6.887 million and fiscal 2009 was US$2.904 million. In March 2009, Synerject negotiated a four (4) year term bank loan of $7.554 million that replaced a four (4) year term loan due to mature June 2010. In addition Synerject has available a US$5.0 million line of credit to be drawn as and when required. At June 30, 2011 Synerject had drawn down $nil under this line of credit. Synerject’s long term loan repayment commitments in fiscal 2012 are approximately US$1.889 million (actual paid fiscal 2011 US$1.889 million) and it is expected that Synerject will fund these repayments out of operating cash surpluses during the year. Synerject’s cash at June 30, 2011 was US$5.754 million (2010 US$4.623 million) and total debt outstanding (including the line of credit) at June 30, 2011 was US$3.462 million (2010 US$7.939 million). Member guarantees are not required to support Synerject’s financing arrangements.

Trend Information

OAGS is expected to see revenue growth as the newly developed LPG system for the EcoLPi Falcon was launched by Ford Australia in July 2011.

Consulting services revenue can be cyclical in nature and the order book (thus future revenue and cash flows) at July 31, 2011 was approximately $4.6 million compared to $3.4 million at June 30, 2010.

The Synerject result will be influenced by the timing of the launch of new products in China and North America and the recovery of the North American marine market.

Sprint Gas is expected to experience a challenging year for sales in the Australian LPG market which has contracted over recent years.

Off-Balance Sheet Arrangements

There have been no off-balance sheet arrangements in fiscal 2011, fiscal 2010 or fiscal 2009.

Inflation

Orbital’s operating costs are subject to the effects of inflation, and under the terms of Orbital’s licence agreements, certain fees and royalty payments are, or will be, indexed to inflation, generally based on the US Producers Price Index for Finished Goods. In general, inflation has had minimal effect on Orbital’s results of operations during the last two fiscal years.

Board Practices

The directors (excluding the Managing Director) are subject to retirement by rotation, with one-third retiring each year (or the number nearest to one-third of the number of directors if not a multiple of three), and may not continue to hold office without re-election after the third Annual General Meeting of shareholders following their last election by the shareholders.

2. REMUNERATION AT A GLANCE

Orbital’s remuneration strategy is designed to attract, motivate and retain employees and non-executive directors by identifying and rewarding high performers and recognising the contribution of each employee to the continued growth and success of the Group.

There have been no material changes to the medium-term incentive (MTI) bonus plan for the 2011 financial year. As in previous years, incentive payments are based on 1) Profit after tax, 2) Operating Cash Flow, and 3) Pro-rata Consolidated Sales.

Long-term incentive (LTI) awards consisting of shares that vest based on attainment of pre-determined performance goals are awarded to select executives. For the 2011 financial year, the Company used relative total shareholder return and earnings per share as the performance measures for the share awards. During the 2011 financial year, the performance hurdles for the 2008 grant of shares were not met and no shares were vested.

As a result of the one for ten share consolidation conducted by the Company during the financial year, all of the LTI targets impacted by the number of shares outstanding have been reset to maintain their relativity.

- 34 -

The remuneration of non-executive directors of the Company consists only of directors’ fees and committee fees. Director fees and committee fees were reviewed and adjusted during the year. The Chairman, Mr Peter Day, sacrificed a portion of his directors fee in the 2011 financial year.

Remuneration strategy

Orbital’s remuneration strategy is designed to attract, motivate and retain employees and non-executive directors by identifying and rewarding high performers and recognising the contribution of each employee to the continued growth and success of the Group.

To this end, key objectives of the Company’s reward framework are to ensure that remuneration practices:

• Are aligned to the Group’s business strategy

• Offer competitive remuneration benchmarked against the external market

• Provide strong linkage between individual and Group performance and rewards

• Align the interests of executives with shareholders through measuring total shareholder return (TSR)

3. BOARD OVERSIGHT OF REMUNERATION

Human Resources, Remuneration and Nomination Committee

The Human Resources, Remuneration and Nomination Committee reviews and makes recommendations to the Board on remuneration packages and policies applicable to directors, secretary and senior executives of the Company.

Data is obtained from independent surveys to ensure that compensation throughout the Group is set at market rates having regard to experience and performance. In this regard, formal performance appraisals are conducted at least annually for all employees. Compensation packages may include a mix of fixed compensation, performance-based compensation and equity-based compensation.

The Human Resources, Remuneration and Nomination Committee comprises three independent non-executive directors. Further information on the committee’s role, responsibilities and membership can be seen atwww.orbitalcorp.com.au.

Remuneration approval process

The Board approves the remuneration arrangements of the CEO and executives and all awards made under the long-term incentive (LTI) plan, following recommendations from the Human Resources, Remuneration and Nomination Committee. The Board also sets the aggregate remuneration of non-executive directors which is then subject to shareholder approval.

The Human Resources, Remuneration and Nomination Committee approves, having regard to the recommendations made by the CEO, the medium-term incentive (MTI) bonus plan.

Remuneration structure

In accordance with best practice corporate governance, the structure of non-executive directors and executive remuneration is separate and distinct.

4. NON-EXECUTIVE DIRECTOR REMUNERATION ARRANGEMENTS

Remuneration policy

The Board seeks to set aggregate remuneration at a level that provides the Company with the ability to attract and retain directors of the highest calibre, whilst incurring a cost that is acceptable to shareholders.

The amount of aggregate remuneration sought to be approved by shareholders and the fee structure is reviewed against fees paid to non-executive directors of comparable companies. The Board considers advice from external consultants when undertaking the review process.

The Company’s constitution and the ASX listing rules specify that the non-executive directors’ fee pool shall be determined from time to time by a general meeting. The latest determination was at the 2001 annual general meeting (AGM) held on 25 October 2001 when shareholders approved an aggregate fee pool of $400,000 per year.

- 35 -

The Board did not seek any increase for the non-executive director pool at the 2011 AGM.

Structure

The remuneration of non-executive directors consists of directors’ fees and committee fees. Non-executive directors do not receive retirement benefits, nor do they participate in any incentive programs.

The Chairman of the Board receives a fee of $105,000 which also covers membership of Committees of the Board. The Chairman sacrificed a portion of his fee in the 2011 financial year. Each non-executive director receives a base fee of $55,000 for being a director of the Group. An additional fee of $3,500 is also paid for each Board committee on which a non-executive director sits or $8,000 if the director is the Chairman of a Board committee. The payment of additional fees for serving on a committee recognises the additional time commitment required by non-executive directors who serve on committees.

The remuneration of non-executive directors for the year ended June 30, 2011, 2010 and 2009 is detailed in Section 8 of this report.

5. EXECUTIVE REMUNERATION ARRANGEMENTS

Remuneration levels and mix

The Group aims to reward executives with a level and mix of remuneration commensurate with their position and responsibilities within the Group and aligned with market practice. The Group undertakes an annual remuneration review to determine the total remuneration positioning against the market.

The CEO’s target remuneration mix comprises 60% fixed remuneration, 20% target MTI opportunity and 20% LTI. The LTI value is the total accounting expense associated with the grant made during the financial year. Executives’ target remuneration mix ranges from 65-85% fixed remuneration, 8-20% target MTI opportunity and 7-15% LTI.

Structure

In the 2011 financial year, the executive remuneration framework consisted of the following components:

• Fixed remuneration

• Variable remuneration (MTI and LTI)

The table below illustrates the structure of Orbital Corporation Limited’s executive remuneration arrangements:

Remuneration component	Vehicle	Purpose	Link to performance
Fixed compensation	•   Represented by total fixed remuneration (TFR). •   Comprises base salary, Superannuation contributions and other benefits.	•   Set with reference to role, market and experience. •   Executives are given the opportunity to receive their fixed remuneration in a variety of forms including cash and fringe benefits such as motor vehicles. It is intended that the manner of payment chosen will be optimal for the recipient without creating undue cost for the Group.	•   No link to company performance.
MTI component	•   Paid in cash.	•   Rewards executives for their contribution to achievement of Group outcomes.	•   Profit after tax. •   Pro-rata Consolidated Sales. •   Operating Cash Flows.
LTI component	•   Awards are made in the form of shares or performance rights.	•   Rewards executives for their contribution to the creation of shareholder value over the longer term.	•   Vesting of awards is dependent on Orbital Corporation Limited’s TSR performance relative to a peer group and its Earnings Per Share.

- 36 -

Fixed compensation

Fixed compensation consists of base compensation (which is calculated on a total cost basis and includes any FBT charges related to employee benefits including motor vehicles), as well as employer contributions to superannuation funds.

Executive contracts of employment do not include any guaranteed base pay increases. TFR is reviewed annually by the remuneration committee. The process consists of a review of company, business unit and individual performance, relevant comparative remuneration internally and externally and, where appropriate, external advice independent of management.

The fixed component of executives’ remuneration is detailed in section 8.

Variable remuneration — short-term incentive (STI)

Orbital does not provide a STI for KMP.

Variable remuneration — medium-term incentive (MTI)

The medium term incentive, replacing the short term incentive, was established in 2009 to incentivise executives to achieve stretch key performance indicators (KPI’s). The MTI plan is a target based plan rather than a time based plan.

Executive directors and senior executives may receive MTI bonuses based on the achievement of key performance indicators (“KPI’s”) related to the performance of the Group over the medium term. The three KPI’s chosen by the Human Resource, Remuneration and Nomination Committee in August 2009 relate to 1) Profit after tax, 2) Operating Cash Flow, and 3) Pro-rata Consolidated Sales. These three measures are chosen as they directly align the individual’s reward to the Group’s strategy and performance.

The KPI’s are summarised as follows:

Key Performance Indicator	Proportion of MTI award KPI applies to			Minimum  KPI $’000		Stretch  KPI $’000
Financial measure:
•   Profit after tax		33	%		100		9,000
•   Operating Cash Flow		33	%		100		2,700
•   Pro-rata Consolidated Sales		33	%		100,000		150,000

Bonuses can only be paid if Orbital generates a profit after tax and also generates positive operating cash flow (before working capital movements). Abnormal one-off items influencing the KPIs may be excluded at the discretion of the Human Resources, Remuneration and Nomination Committee. No bonus will be paid unless the Board is satisfied that Orbital has sufficient cash reserves.

Bonuses are awarded when a target is achieved which is higher than that which has already been achieved and rewarded. The MTI earned accumulates over time as targets are achieved with any incremental MTI earned paid annually.

The total potential MTI available is set at a level so as to provide sufficient incentive to executives to achieve the operational targets and such that the cost to the Group is reasonable in the circumstances.

The annual MTI payments for executives are subject to the approval of the Human Resources, Remuneration and Nomination Committee on an annual basis, after consideration of performance against KPIs. This process usually occurs within three months after the reporting date. Payments made are delivered as a cash bonus in the following reporting period.

MTI awards for 2010 and 2011 financial years

For the 2010 financial year, 100% of the MTI cash bonus of $406,645 as previously accrued in that period vested to executives, however all participants in the MTI scheme voluntarily and irrevocably waived their right to their MTI cash bonuses. The Group recorded a reversal of the MTI cash bonus of $406,645 during the current financial year.

The Human Resources, Remuneration and Nomination Committee has considered the MTI bonus for the 2011 financial year. The MTI cash bonus available for the 2011 financial year is nil. This amount has been determined on the basis that 1) the Group’s Profit after tax (after removing abnormal items) target for the year ended 30 June 2011 has been met, however 2) Positive Operating Cash Flows for the year ended 30 June 2011 were not achieved, and 3) the Consolidated Pro-rata Sales of the Group have not reached the minimum threshold of $100,000,000.

- 37 -

During the year the MTI bonus plan was altered so that Positive Operating Cash Flow (excluding working capital movements) is now a pre-requisite for the payment of any MTIs.

Estimates of the minimum and maximum possible total value of the award over time are as follows:

Name	Position	Amount (Min – Max)
Terry Stinson	Chief Executive Officer	0 - $	630,000
Keith Halliwell	Chief Financial Officer	0 - $	359,478
Tony Fitzgerald	Director, Orbital Autogas Systems	0 - $	332,013
Geoff Cathcart	Director, Consulting Services and Engineering	0 - $	269,325
David Worth	Director, Business Development, OCS	0 - $	166,971
Ian Veitch	Company Secretary	0 - $	72,114

The maximum bonus is only payable if the stretch targets on all three of the KPI’s are achieved. No bonus is awarded where performance falls below minimum thresholds.

Variable remuneration — long-term incentives (LTI)

LTI awards are made annually to executives in order to align remuneration with the creation of shareholder value over the long-term. As such, LTI awards are only made to executives and other key talent who have an impact on the Group’s performance against the relevant long-term performance measure.

Employee Share Plan No.1

Senior executives (together with all other eligible employees) are each offered shares in the Company, at no cost to the employees, to the value of $1,000 per annum under the terms of the Company’s Employee Share Plan. There are no performance conditions, because the plan is designed to align the interests of participating employees with those of shareholders. Directors do not participate in Share Plan No.1.

Executive Long Term Share Plan

Executives may also be offered rights in the Company’s Executive Long Term Share Plan under which offered shares will vest for no consideration subject to the satisfaction of performance conditions over a 3 year period or subject to Board discretion for other qualifying reasons. The performance conditions, which are based 50% on the relative ranking of the Total Shareholder Return (“TSR”) of the Company to a group of selected peers, and 50% on Earnings Per Share (EPS) (FY2009: based 100% on TSR), apply to determine the number of shares (if any) that vest to the Executives.

TSR is the percentage increase in a company’s share price plus reinvested dividends over a given period and reflects the increase in value delivered to shareholders over that period. The peer group to which the Company’s TSR will be compared will comprise the 50 smallest companies, other than resource companies and property and investment trust companies, within the S&P / ASX 300 Index. These companies have a similar market capitalisation to the Company. The TSR performance criterion was chosen as it is widely accepted as one of the best indicators of shareholder wealth creation as it includes share price growth, dividends and other capital adjustments. In addition, this criterion provides a readily obtained objective means of measuring the Group’s performance against its peer group.

The Company’s TSR ranking at the end of the Performance Period, when compared to the TSR of the peer group will determine the percentage of shares originally offered which will vest to the Executive.

- 38 -

The following table sets out the relevant percentages of shares offered which will vest based on various percentile rankings of the Company:

Company Performance (TSR Ranking)	% of offered shares issued to each executive
Up to the 50th percentile	0%
At or above the 50th percentile but below the 75th percentile	50% to 99% (on a straight line basis)
At or above the 75th percentile but below the 90th percentile	100%
At or above the 90th percentile	125%

No shares will be granted under the FY2009 offer unless the Company’s TSR is at or above the 50th percentile.

No shares will be granted under the FY2011 and FY2010 offers unless the Company’s TSR is at or above the 50th percentile or the EPS for the years ended 30 June 2012 and 30 June 2013 is at or above 15 and 11 cents per share, respectively.

TSR Performance targets under the LTI offered in FY2008 were not met in FY2011 and as a result nil (2010: 911,400) shares were issued to KMPs.

At the Company’s Annual General Meeting in October 2010, shareholders approved the above plan in relation to the ongoing remuneration of the Executive Director.

Performance Rights Plan

The Company also introduced a Performance Rights Plan in 2009 as part of the employment contact of Mr T D Stinson. The Performance Rights Plan was approved by shareholders in October 2008. The Board has no present intention to utilise the Performance Rights Plan for any other senior executives.

Under the Performance Rights Plan, performance rights will only be issued if the terms and conditions detailed below are satisfied.

A performance right is a right to acquire one fully paid ordinary share in the Company. Until they are exercised, performance rights:

(a) do not give the holder a legal or beneficial interest in shares of the Company; and

(b) do not enable participating executives to receive dividends, rights on winding up, voting rights or other shareholder benefits.

Performance rights issued under the Performance Rights Plan will be exercisable if:

(a) a performance hurdle is met over the periods specified by the Board; or

(b) the Board allows early exercise on cessation of employment; or

(c) it is determined by the Board in light of specific circumstances.

The terms and conditions of the offer of Performance Rights made during the year ended 30 June 2009 are as follows:

(a) Mr T D Stinson will be awarded 1,150,000 performance rights;

(b) the grant of performance rights will be in seven tranches, each tranche with a different specified share price target as set out below:

Tranche	Number of performance		Share price target
1		200,000	$	2.50
2		200,000	$	5.00
3		200,000	$	7.50
4		200,000	$	10.00
5		125,000	$	20.00
6		125,000	$	30.00
7		100,000	$	50.00

- 39 -

The target share prices were chosen as they directly align the director’s reward with group strategy.

(c) the acquisition price and exercise price of the performance rights will be nil.

(d) Mr T D Stinson will only be permitted to exercise a performance right if:

• the Company attains the specified share price target (see table above) within eight years from the date of grant of the performance right; and

• the specified share price target is also achieved at the end of two years from the date the target is first achieved (“Vesting Date”) based on the Company’s average closing share price over a 90 day period up to and including the Vesting Date;

(e) If the specified share price target is either not achieved within eight years from the date of grant, or if so achieved, not also achieved at the end of the Vesting Date, the performance right will lapse.

No performance rights were granted during the year ended 30 June 2011.

Termination and change of control provisions

Where a participant ceases employment prior to the vesting of their award, the unvested shares are forfeited unless the Board applies its discretion to allow vesting at or post cessation of employment in appropriate circumstances.

In the event of a change of control of the Group, the performance period end date will generally be brought forward to the date of the change of control and awards will vest subject to performance over this shortened period, subject to ultimate Board discretion.

LTI awards for 2011 financial year

Shares were granted under the Employee Share Plan No.1 to a number of executives on 17 January 2011. No Shares were granted under the Executive Long Term Share Plan or the Performance Rights Plan during the 2011 financial year.

Details in respect of the award are provided in Section 9.

6. COMPANY PERFORMANCE AND THE LINK TO REMUNERATION

Company performance and its link to medium-term incentives

Performance linked compensation includes both medium-term and long-term incentives and is designed to reward key management personnel for meeting or exceeding their financial and personal objectives. The medium-term incentive (MTI), which has replaced the short term incentive, is an “at risk” bonus provided in the form of cash, while the long-term incentive (LTI) is provided as ordinary shares of Orbital Corporation Limited under the rules of the various Share Plans.

In considering the Group’s performance and benefits for shareholders wealth the Human Resources, Remuneration and Nomination Committee has regard to the following indices in respect of the current financial year and the previous four financial years.

Profit after tax, Pro-rata Consolidated Sales and Operating Cash Flows are considered in setting the MTI as they are considered important medium term performance targets.

Company performance for the current year, the last 4 years and KPI targets are as follows:

	2007 $’000			2008 $’000		2009 $’000			2010 $’000			2011 $’000			Minimum KPI $’000		Stretch KPI $’000
Profit after tax		1,333			469		(2,451	)		4,516			1,763			positive		9,000
Operating Cash Flow		(182	)		73		(856	)		(4,372	)		(584	)		positive		2,700
Pro-rata Consolidated Sales		65,004			59,875		63,867			61,081			65,889			100,000		150,000
Operating Cash Flow (before working capital movements)*		(250	)		901		(2,372	)		(2,934	)		(833	)		positive		Not applicable

* A positive operating cash flow (before working capital movements) must be achieved as a pre-condition for the payment of any MTI.

- 40 -

Company performance and its link to long-term incentives

The performance measure which drives LTI vesting is the Company’s TSR performance relative to the companies within its peer group and earnings per share (EPS). The table below show the performance of the Group as measured by the Group’s total shareholder return (TSR) to the median of the TSR for peer group and also the Group’s earnings per share for the past five years (including the current period) to 30 June 2011. The earnings per share values in the table below have been adjusted to reflect the share consolidation undertaken during the reporting period.

Company performance for the current year and last 4 years is as follows:

	2007		2008		2009			2010		2011		2012 Minimum		2013 Minimum
TSR ranking (percentile)		*		76th		70th			56th		*		50th		50th
Earnings per share (cents)		3.00		1.00		(5.10	)		9.39		3.65		15.00		11.00

* The Company did not measure its TSR ranking in 2007 or 2011 as the Board determined that Orbital’s TSR would be below the median TSR of the peer group.

As a result of the Company’s performance over the last five years, LTIs offered during 2005, 2006 and 2007 were fully vested in financial year 2008 and partially vested in financial years 2009 and 2010 respectively. The performance target for the LTIs offered in 2008 was not met during the financial year 2011 and as such no shares were vested.

TSR related rights

The following factors and assumptions were used in determining the fair value of TSR related rights issued under the ELTSP on grant date:

Grant Date	Life	Fair Value per right	Exercise Price	Market price of shares on grant date	Expected volatility			Risk free interest rate
31-Aug-08	3 years	58 cents	nil	79 cents		62.70	%		5.68	%
31-Aug-09	3 years	38 cents	nil	55 cents		65.00	%		5.03	%
31-Aug-10	3 years	33 cents	nil	34 cents		60.00	%		4.27	%

- 42 -

EPS related rights

The following factors and assumptions were used in determining the fair value of EPS related rights issued under the ELTSP on grant date:

Grant Date	Life	Fair Value per right	Exercise Price	Market price of shares on grant date
31-Aug-09	3 years	55 cents	nil	55 cents
31-Aug-10	3 years	34 cents	nil	34 cents

The fair value of the EPS related rights is equal to the market price of shares on the grant date.

The fair value of the Performance Rights is calculated at the date of grant through utilisation of the assumptions underlying the Black-Scholes methodology to produce a Monte-Carlo simulation model and allocated to each reporting period evenly over the period from grant date to vesting date. The value disclosed is the portion of the fair value of the performance rights recognised in this reporting period. In valuing the performance rights the hurdles that must be met before the executive long term share plan shares vest in the holder have been taken into account.

Grant Date	Life	Fair Value per right	Target price		Market price of shares on grant date	Expected volatility			Risk free interest rate
31-Aug-08	10 years	47 cents	$	2.50	79 cents		55.00	%		5.75	%

Notes in relation to the table of directors’ and executive officers remuneration

(a) Bonuses are those paid or accrued as payable in relation to the year reported. For the 2010 financial year, 100% of the MTI cash bonus of $406,645 as previously accrued in that period vested to executives, however all participants in the MTI scheme voluntarily and irrevocably waived their right to their MTI cash bonuses. The Group recorded a reversal of the MTI cash bonus of $406,645 during the current financial year.

(b) The fair value of the Employee Share Plan #1 is based upon the market value (at offer date) of shares offered.

(c) The fair value of the Executive Long Term Share plan (“ELTSP”) is calculated at the date of grant through utilisation of the assumptions underlying the Black-Scholes methodology to produce a Monte-Carlo simulation model and is allocated to each reporting period evenly over the period from grant date to vesting date. The value disclosed is the portion of the fair value of the rights recognised in this reporting period. In valuing the rights the market based hurdles that must be met before the executive long term share plan rights vest in the holder have been taken into account.

Corporate Governance

The following outlines the main Corporate Governance practices of the Company that were in place throughout the financial year:

1. CORPORATE GOVERNANCE AT ORBITAL

The Board of Directors is responsible for the corporate governance of Orbital. The Board guides and monitors the business and affairs of the Group on behalf of the shareholders by whom they are elected and to whom they are accountable. This statement reports on Orbital’s key governance principles and practices. These principles and practices are reviewed regularly and revised as appropriate to reflect changes in law and developments in corporate governance.

Orbital, as a listed entity, must comply with theCorporations Act 2001 (Cwth) (Corporations Act), the Australian Securities Exchange (ASX) Listing Rules (ASX Listing Rules) and other Australian and international laws. The ASX Listing Rules requires the Company to report on the extent to which it has followed the Corporate Governance Recommendations contained in the ASX Corporate Governance Council’s (ASXCGC) second edition of its Corporate Governance Principles and Recommendations (August 2007). Orbital believes that, throughout the 2011 fiscal year and to the date of this report, it has complied with all the ASXCGC Recommendations.

Information on Orbital’s corporate governance framework is also provided in the Corporate Governance section of Orbital’s website (www.orbitalcorp.com.au)

2. BOARD OF DIRECTORS

2.1 Role of the Board

The Board’s primary role is to protect and enhance long-term shareholder value by providing strategic guidance to the Group and effective oversight of management.

To fulfil this role, the Board is responsible for the overall corporate governance of the Group including formulating its strategic direction, approving and monitoring capital expenditure, setting remuneration, appointing, removing and creating succession policies for directors and senior executives, establishing and monitoring the achievement of management’s goals and ensuring the integrity of internal control and management information systems.

It is also responsible for approving and monitoring financial and other reporting. A copy of the Board’s Charter is available in the Corporate Governance section of Orbital’s website.

The Board has delegated responsibility for operation and administration of the Group to the Chief Executive Officer and executive management. Responsibilities are delineated by formal authority delegations.

The Board conducts an annual review of its processes to ensure that it is able to carry out its functions in the most effective manner.

2.2 Composition of the Board

The names and qualifications of the directors of the Company in office at the date of this Report are detailed in the Directors’ Report in Item 6 on page 31.

The composition of the Board is determined using the following principles:

• A minimum of three directors, with a broad range of expertise;

• An independent non-executive director as Chairman;

• A majority of independent non-executive directors; and

• The role of Chief Executive Officer (CEO) and Chairman should not be exercised by the same individual.

- 47 -

An independent director is a non-executive director who:

• is not a substantial shareholder of the Company or an officer of, or otherwise associated directly with, a substantial shareholder of the Company;

• within the last three years has not been employed in an executive capacity by the Company or another Group member, or been a director after ceasing to hold any such employment;

• within the last three years has not been a principal of a professional adviser or a consultant to the Company or another Group member, or an employee materially associated with the service provided;

• is not a material* supplier or customer of the Company or other Group member, or an officer of or otherwise associated directly or indirectly with a material supplier or customer;

• has no material* contractual relationship with the Company or another Group member other than as a director of the Company;

• has not served on the board for a period which could, or could reasonably be perceived to, materially interfere with the director’s ability to act in the best interests of the Company; and

• is free from any interest and any business or other relationship which could, or could reasonably be perceived to, materially interfere with the director’s ability to act in the best interests of the Company.

* No non-executive director is a supplier to or customer of the Group, nor does any non-executive Director have a contractual relationship with the Group (other than as a director of the Company) and therefore the Board has not had to consider any materiality threshold.

2.3 Conflicts of Interest

In accordance with the Corporations Act 2001 and the Company’s constitution, directors must keep the Board advised, on an ongoing basis, of any interest that could potentially conflict with those of the Company. Where the Board believes that a significant conflict exists the director concerned must not be present at the meeting whilst the item is considered or vote on the matter. The Board has procedures in place to assist directors to disclose potential conflicts of interest.

2.4 Board Succession Planning

The Board manages its succession planning with the assistance of the Human Resources, Remunerations and Nominations Committee. The Committee annually reviews the size, composition and diversity of the Board and the mix of existing and desired competencies across members and reports its conclusions to the Board. In conducting the review a skills matrix is used to enable the Committee to assess the skills and experience of each director and the combined capabilities of the Board.

Recognising the importance of Board renewal, the Committee takes each director’s tenure into consideration in its succession planning.

2.5 Directors’ Retirement and Re-election

Non-executive directors must retire at the third Annual General Meeting (“AGM”) following their election or most recent re-election. At least one non-executive director must stand for election at each AGM. Any director appointed to fill a vacancy since the date of the previous AGM must submit themselves to shareholders for election at the next AGM.

Board support for a director’s re-election is not automatic and is subject to satisfactory director performance.

2.6 Directors’ Appointment, Induction Training and Continuing Education

All new directors are required to sign and return a letter of appointment which sets out the key terms and conditions of their appointment, including duties, rights and responsibilities, the time commitment envisaged and the Board’s expectations regarding their involvement with committee work.

As part of the induction process, new directors are provided with detailed information about the nature of the Group’s business, current issues, group strategy, financial matters, policies and procedures and are given the opportunity to meet with management to obtain an insight into the Group’s business operations.

All directors are expected to maintain the skills required to discharge their obligations to Orbital. Directors are encouraged to undertake continuing professional education including industry seminars and approved education courses.

- 48 -

2.7 Board Access to Independent Professional Advice and Company Information

Each director has the right of access to all relevant Company information and to the Group’s executives and, subject to prior consultation with the Chairman, may seek independent professional advice from a suitably qualified adviser at the Group’s expense. The director must consult with an advisor suitably qualified in the relevant field, and obtain the Chairman’s approval of the fee payable for the advice before proceeding with the consultation. A copy of the advice received by the director is made available to all other members of the Board.

2.8 Review of Board Performance

The Human Resources, Remuneration and Nomination Committee is responsible for determining the process for evaluating Board performance. Evaluations are conducted by way of questionnaires appropriate in scope and content to effectively review:

• the performance of the Board and each of its committees against the requirements of their respective charters; and

• the individual performance of the Chairman and each director.

The performance of each director retiring at the next AGM is taken into account by the Board in determining whether or not the Board should support the re-election of the director.

2.9 Directors’ Remuneration

Details of remuneration paid to directors (executive and non-executive) are set out in the Remuneration Report on page 44. The Remuneration Report also contains information on the Company’s policy for determining the nature and amount of remuneration for directors and senior executives and the relationship between the policy and company performance.

Shareholders were invited to consider and approve the Remuneration Report at the 2011 AGM.

2.10 Board Meetings

The full Board currently holds six scheduled meetings each year, plus strategy meetings and any extraordinary meetings at such other times as may be necessary to address any specific significant matters that may arise.

The agenda for meetings is prepared in conjunction with the Chairman, Managing Director and Company Secretary. Standing items include the managing director’s report, financial reports, strategic matters, governance and compliance. Submissions are circulated in advance. Executives are regularly involved in board discussions and directors have other opportunities, including visits to operations, for contact with a wider group of employees.

2.11 Company Secretary

Mr Ian G Veitch, B.Bus, GradDipACG, CA, ACIS was appointed to the position of Company Secretary on 1 July 2009. He is a Chartered Accountant and Chartered Secretary with over 17 years experience in corporate accounting and is also a Member of Chartered Secretaries Australia.

The appointment and removal of a Company Secretary is a matter for decision by the Board. The Company Secretary is responsible for ensuring that Board procedures are complied with and that governance matters are addressed.

3. COMMITTEES OF THE BOARD

3.1 Board Committees, Membership and Charters

To assist in the execution of its responsibilities, the Board has established a number of Board Committees including an Audit Committee and a Human Resources, Remuneration and Nomination Committee. These committees have written mandates and operating procedures, which are reviewed on a regular basis. The effectiveness of each committee is also constantly monitored. The Board has also established a framework for the management of the Group including a system of internal control and the establishment of appropriate ethical standards.

- 49 -

3.2 Audit Committee

The role of the Audit Committee is to give the Board of Directors additional assurance regarding the quality and reliability of financial information prepared for use by the Board in determining accounting policies for inclusion in the financial report. The Committee has a documented charter, approved by the Board. A copy of the Audit Committee’s Charter is available in the Corporate Governance section of Orbital’s website. All members of the Committee must be independent, non-executive directors.

Members of the Audit Committee during the year were Mr J G Young (Chairman – 1 July 2010 to 28 February 2011), Dr M T Jones (Chairman – from 28 February 2011), Mr W P Day and Dr V Braach-Maksvytis. The external auditors, Chief Executive Officer, Chief Financial Officer, Company Secretary and other financial and accounting staff are invited to Audit Committee meetings at the discretion of the Committee. The Chief Executive Officer and Chief Financial Officer declared in writing to the Board that the Company’s financial reports for the year ended 30 June 2011 present a true and fair view, in all material respects, of the Company’s financial condition and operational results and are in accordance with relevant accounting standards. This statement is required annually.

The responsibilities of the Audit Committee include, liaising with the external auditors and ensuring that the annual and half-year statutory audits/reviews are conducted in an effective manner; reviewing and ensuring management implement appropriate and prompt remedial action for any deficiencies identified; monitoring compliance with Australian and international taxation requirements; the Australian and United States corporations laws and ASX Listing Rules; and improving quality of the accounting function.

The Audit Committee reviews the performance of the external auditors on an annual basis and meets with them to discuss audit planning matters, statutory reporting and as required for any special reviews or investigations deemed necessary by the Board. The Audit Committee also assesses whether non-audit services provided by the external auditor are consistent with maintaining the external auditor’s independence and provides advice to the Board whether the provision of such services by the external auditor is compatible with the general standard of independence of auditors imposed by the Corporations Act. The Audit Committee charter provides for rotation of the external audit partner every five years.

3.3 Human Resources, Remuneration and Nomination Committee

The role of the Human Resources, Remuneration and Nomination Committee is to review and make recommendations to the Board on the remuneration packages and policies applicable to the Chief Executive Officer, senior executives and directors. It also plays a role in evaluation of the performance of the Chief Executive Officer and management succession planning. This role also includes responsibility for employee share schemes, incentive performance packages, superannuation entitlements, fringe benefits policies and professional indemnity and liability insurance policies. From time-to-time, the Remuneration Committee obtains independent advice on the appropriateness of remuneration packages, given trends in comparative companies both locally and internationally.

The Committee also oversees the appointment and induction process for directors. It reviews the composition of the Board and makes recommendations on the appropriate skill mix, personal qualities, expertise and diversity. When a vacancy exists or there is a need for particular skills, the Committee, in consultation with the Board, determines the selection criteria based on the skills deemed necessary. Potential candidates are identified by the Committee with advice from an external consultant, where appropriate. The Board then appoints the most suitable candidate who must stand for election at the next general meeting of shareholders. The Nomination Committee is also responsible for the selection, appointment and succession planning process of the Company’s Chief Executive Officer.

Members of the Human Resources, Remuneration and Nomination Committee during the year were Dr M T Jones (Chairman – 1 July 2010 to 28 February 2011), Dr V Braach-Maksvytis (Chairman – from 28 February 2011), Mr W P Day and Mr J G Young (retired 28 February 2011).

The Human Resources, Remuneration and Nomination Committee meet as and when required. The Committee has a documented charter, approved by the Board. A copy of the Human Resources, Remuneration and Nomination Committee’s Charter is available in the Corporate Governance section of Orbital’s website.

The performance of all Directors is reviewed by the Chairman each year. Directors whose performance is unsatisfactory are asked to retire.

4 SHAREHOLDERS

4.1 Shareholder Communication

Directors recognise that shareholders, as the ultimate owners of the Company, are entitled to receive timely and relevant high quality information about their investment. Similarly, prospective new investors are entitled to be able to make informed investment decisions when considering the purchase of shares.

Information is communicated to shareholders as follows:

• The disclosure of full and timely information about Orbital’s activities in accordance with the disclosure requirements contained in the ASX Listing Rules and the Corporations Act;

• All information released to the market to be placed on the Company’s website promptly following release;

• The annual financial report is distributed to all shareholders (and to American Depositary Receipt (ADR) holders) on request in accordance with Corporation Act requirements and includes relevant information about the operations of the Group during the year, changes in the state of affairs of the Group and details of future developments, in addition to other disclosures required by the Corporations Act and US securities law;

The half-year financial report is prepared in accordance with the requirements of Accounting Standards and the Corporations Act and is lodged with Australian and United States regulatory bodies and stock exchanges. Financial reports are sent to any shareholder or ADR holder who requests them; and

The Board encourages participation of shareholders at the Annual General Meeting to ensure a high level of accountability and identification with the Group’s strategy and goals. Important issues are presented to the shareholders as single resolutions. The Company’s external auditor is requested to attend annual general meetings to answer any questions concerning the audit and the content of the auditor’s report.

Shareholders are requested to vote on the appointment of Directors, aggregate remuneration of non-executive directors, the granting of shares to Directors and changes to the Constitution. A copy of the Constitution is available to any shareholder who requests it.

4.2 Continuous Disclosure and Market Communications

The Board of Directors aims to ensure that shareholders are informed of all major developments affecting the Group’s state of affairs. The Board has adopted a policy to identify matters that may have a material effect on the price of the Company’s securities and to notify the ASX as required.

This policy on Release of Price Sensitive Information is overseen and coordinated by the Company Secretary. All directors, officers and members of the Company’s management committee are required to forward details of any potentially price sensitive information to the Company Secretary, who is also to be made aware, in advance, of proposed information disclosures (including information to be presented at private briefings) to enable consideration of the continuous disclosure requirements. Proposed announcements are to be approved by the Managing Director and either the Chairman or Company Secretary prior to release to the ASX. The Company Secretary is responsible for all communications with the ASX.

The Company’s policy on Release of Price Sensitive Information and its policy on communication with shareholders are available in the Corporate Governance Section of Orbital’s website.

5. PROMOTING RESPONSIBLE AND ETHICAL BEHAVIOUR

5.1 Code of Conduct and Whistleblower Policy

All Directors, managers and employees are expected to act with the utmost integrity and objectivity, striving at all times to enhance the reputation and performance of the Group. Every employee has a nominated supervisor to whom they may refer any issues arising from their employment. The Board has approved a Code of Conduct, applicable to all Directors and employees of the Group, providing for the conduct of business in accordance with the highest ethical standards and sound corporate governance. The Code also incorporates the Company’s policy on trading in the Company’s securities. A Code of Ethics, relating to Accounting Practice and Financial Reporting, has also been adopted by the Board and applies specifically to the Chief Executive Officer, Chief Financial Officer and senior finance officers of the Company who influence financial performance. The Code of Ethics is complementary to the Code of Conduct, copies of both of which are available in the Corporate Governance section of Orbital’s website.

- 51 -

5.2 Securities Ownership and Dealing

The Company’s policy with respect to Directors and Officers dealing in the Company’s shares or options states that:

• Directors and Officers are prohibited from dealing in the Company’s securities at any time when they possess information which, if publicly disclosed, would be likely to affect the market price of the Company’s securities;

• Directors and Officers are prohibited from short term trading in the Company’s securities;

• Directors must obtain the written approval of the Chairman before undertaking any transactions involving the Company’s securities; and

• Directors and Officers are prohibited from undertaking transactions in the Company’s securities during the period from one month prior to the proposed release of the Company’s annual or half-year result until two days after that release.

A copy of the Securities Trading Policy is available in the Corporate Governance section of Orbital’s website.

6. RISK MANAGEMENT

6.1 Approach to Risk Management and Internal Control

The Board oversees the establishment, implementation and review of the Company’s risk management systems, which have been established by management for assessing, monitoring and managing operational, financial reporting and compliance risks for the Group. Responsibility for establishing and maintaining effective risk management strategies rests with senior management, accountable to the Chief Executive Officer and the Audit Committee of the Board. The Audit Committee reviews the risk management and internal control structure implemented by management so as to obtain reasonable assurance that the Group’s assets are safeguarded and that reliable financial records are maintained. Operational and other compliance risk management has also been reviewed and found to be operating efficiently and effectively. A copy of the Company’s risk management policy is available in the Corporate Governance section of Orbital’s website.

Risks to the Group arise from matters such as competitive technologies that may be developed, delays in government regulation, reduction in development and testing expenditure by the Company’s customers, the impact of exchange rate movements, environmental issues, occupational safety and health and financial reporting.

6.2 Internal Control Framework

The Board recognises that no cost effective internal control system will preclude all errors and irregularities. The system is based upon written procedures, policies and guidelines, an organisational structure that provides an appropriate division of responsibility, and the careful selection and training of qualified personnel.

Established practices ensure:

• Capital expenditure commitments are subject to authority level approval procedures;

• Financial exposures are controlled by the use of forward exchange contracts, where appropriate;

• Occupational safety and health issues are monitored by a management committee;

• Financial reporting accuracy and compliance with regulatory requirements; and

• Compliance with environmental regulation.

Where risks, such as natural disasters, cannot be adequately mitigated using internal controls, those risks are transferred to third parties through insurance coverage to the extent considered appropriate.

6.3 Chief Executive Officer and Chief Financial Officer Assurance

The Chief Executive Officer and Chief Financial Officer have declared, in writing to the Board, that the Company’s financial reports are founded on a sound system of risk management and internal compliance and control which implements the policies adopted by the Board, and that they have evaluated the effectiveness of the company’s financial disclosure controls and procedures and have concluded that they are operating efficiently and effectively.

Monthly financial results are reported against budgets approved by the directors and revised forecasts for the year are prepared regularly.

- 52 -

6.4 Environmental Regulation

The Group holds a number of permits, licences and registrations for environmental regulation under both Australian Commonwealth and State legislation. These permits, licences and registrations are primarily for the storage of fuels and chemicals and the disposal of waste and are reviewed by the Group on an on-going basis. The directors are not aware of any serious breaches during the period covered by this report.

7. EXTERNAL AUDITOR RELATIONSHIP

The Audit Committee oversees the terms of engagement of Orbital’s external auditor. The Audit Committee ensures that the audit approach covers all financial statement areas where there is a risk of material misstatement and that audit activities are carried out throughout the Orbital Group in the most effective, efficient and comprehensive manner.

The Committee has the responsibility for the appointment, compensation and oversight of the external Auditor and to ensure that the external Auditor meets the required standards for Auditor Independence. In monitoring Auditor Independence the Committee will have regard to any legislative or regulatory requirements, and the following principles:

• It is mandatory that the Audit Partner responsible for the Audit be rotated at least every five years. At least two years must expire before the Audit Partner can again be involved in the Audit of the Group.

• The Committee monitors the number of former employees of the external Auditor who were involved in auditing the Company, currently employed in senior financial positions in the Company, and assesses whether this impairs or appears to impair the Auditor’s judgment or independence in respect of the Company. An individual auditor who was engaged by the external Auditor and participated in the Company’s audit shall be precluded from employment as Chief Executive Officer or Chief Financial Officer of the Company for a period of twelve months from the time of the audit.

• Consider whether taken as a whole, the various relationships between the company and the external Auditor and the economic importance of the Company (in terms of fees paid to the external Auditor for the Audit as well as fees paid to the external Auditor for the provision of non-audit services) to the external Auditor impair or appear to impair the Auditor’s judgment or independence in respect of the Company.

• The Company shall not engage its external Auditor for certain non-audit services (including book-keeping, financial information systems design, valuations, actuarial services, internal audit outsourcing, human resources and unrelated legal/expert services). Any proposal to grant the external Auditor non-prohibited non-audit services will be referred to the Chairman of the Audit Committee by management prior to granting the work.

• The Chairman of the Committee will meet (at least annually) with the external Auditors without the presence of management.

Executive Long Term Share Plan - 2011 Offer

At the Company’s Annual General Meeting on October 26, 2011, shareholders approved the participation of the Managing Director, Mr Terry Stinson, in the Company’s Executive Long Term Share Plan. Under this Plan, a performance related offer of shares has been made to the Managing Director and eligible executives of the Company. Mr Stinson has been offered up to 866,250 fully paid ordinary shares.

Shares offered under the Plan will only be granted, at no cost to participants, if performance conditions are met or if, on cessation of employment, there is a Qualifying Reason. The number of shares that the executive actually receives depends on two performance hurdles, as set out below:

(a) 481,250 of the shares offered will be issued depending on the performance of the Company relative to a group of selected peers (being the 50 smallest companies by market capitalisation (other than resource companies and property and investment trust companies) within the S&P / ASX 300 Index. The peer group is ranked in terms of Total Shareholder Return (“TSR”). TSR is the percentage increase in a company’s share price plus reinvested dividends over a three year period commencing on September 1, 2011 and ending on August 31, 2014 (“Performance Period”).

The following table sets out the relevant percentages of an executive’s Personal Allotment which will be issued at the conclusion of the Performance Period based on the TSR ranking of the Company relative to the peer group:

ITEM 9. THE OFFER AND LISTING

Nature Of Trading Market

Orbital’s ordinary shares are traded on the ASX. The ASX is a nationally operated stock exchange with an Automated Trading System in the capital city of each Australian state.

The ordinary shares are also traded in the United States in the form of ADSs evidenced by American Depositary Receipts (“ADRs”) issued by The Bank of New York Mellon as depositary under a deposit agreement dated April 16, 2010. Each ADS represents sixteen ordinary shares. The ADSs have traded on NYSE Amex with effect from August 25, 2011, under the symbol “OBT”. Prior to that time, the ADSs were traded on the Over the Counter Bulletin Board (OTCBB) with effect from July 1, 2004 until August 25, 2011, under the symbol “OBTMY”.

The following table sets forth, for the periods indicated, the high and low closing sale prices per share and the high and low day trade volume of Orbital’s fully paid ordinary shares based upon information provided by the ASX Automated Trading System, and the high and low closing sale prices per ADS and the high and low day trade volume as reported on the OTCBB and NYSE Amex. On October 28, 2010 the shareholders in Annual General Meeting approved the consolidation of ordinary shares on the basis that every ten ordinary shares be consolidated into one ordinary share, and where this consolidation results in a fraction of a share being held by a shareholder, the directors of the Company be authorised to round that fraction up to the nearest whole share. The share consolidation became effective on October 28, 2010. Note that effective April 19, 2010 the ratio of ordinary shares to ADSs was changed from 1 : 40 to 1 : 160 and effective October 31, 2010 the ratio of ordinary shares to ADSs was changed from 1 : 16. Please note that the ADS prices quoted below for dates prior to April 19, 2010 and October 31, 2010 have not been restated to account for the change of ratio of ordinary shares to ADSs.

ITEM 10. ADDITIONAL INFORMATION

Memorandum and Articles (Constitution)

No objects and purposes of the Company are stated or, under Australian law, are required to be stated, in the Company’s Constitution.

At the Company’s Annual General Meeting on October 26, 2004 shareholders voted to adopt a new Constitution for the Company – refer Exhibit 1.1.

Under the Company’s Constitution:

• a Director may not vote in relation to any contract or proposed contract or arrangement in which the Director has, directly or indirectly, a material interest;

• the maximum total of fees payable to Directors is required to be approved by the Company in general meeting;

• the Directors may at any time exercise all the powers of the Company to borrow money, except to the extent that such powers are required by law or the Listing Rules of Australian Stock Exchange Limited to be exercised by the Company in general meeting;

• a Director may not hold office in contravention of the Corporations Act 2001 (Aust.); and

• a Director is not required to have a share qualification.

The Company has fully paid ordinary shares on issue. Dividends, as declared by Directors and which are only payable from profits, are payable on all fully paid ordinary shares equally. Except as otherwise provided by statute, all dividends unclaimed for one year after having been declared may be invested or otherwise made use of by the Directors for the benefit of the Company until claimed.

At meetings of shareholders, each shareholder present in person or by proxy or representative has, on a show of hands, one vote and, on a poll, each shareholder present in person or by proxy or representative has one vote in respect of each fully paid share held by that shareholder. Nothing in the Company’s Constitution discriminates against any existing or prospective holder of shares in the Company as a result of such shareholder owning a substantial number of shares.

Changes to the rights of shareholders in relation to a particular class of shares may only be made with the consent in writing of the holders of three-quarters of the issued shares of that class or if authorised by a special resolution passed at a separate meeting of the holders of that class of share. The Company does not currently have different classes of shares.

Details of requirements for Directors to stand for re-election are set out at “Item 6. Directors, Senior Management and Employees – Board Practices”.

In accordance with the Company’s Constitution, any Director may whenever that Director thinks fit convene a general meeting of shareholders of the Company. Under the Corporations Act 2001, the Directors must call and arrange to hold a general meeting on the signed written request of either members with at least 5% of the votes that may be cast at the general meeting or at least 100 members who are entitled to vote at the general meeting. The request must state any resolution to be proposed at the meeting. The Directors must call the meeting within 21 days after the request is given to the Company and the meeting is to be held not later than 2 months after the request is given to the Company.

Shareholders must be given at least 28 days written notice of a meeting of the Company’s shareholders, which notice may be given personally or by post and must set out:

• the place, date and time of the meeting;

• the general nature of the meeting’s business;

• the resolution, if a special resolution is proposed; and

• a shareholder’s right to appoint a proxy.

The persons entitled to attend a general meeting of the Company shall be the shareholders (in person, by proxy or representative), the directors, the Company’s auditor and such other person or persons as the meeting may approve.

There are no limitations under the Constitution of Orbital to the right of non-residents to hold or vote ordinary shares.

- 61 -

Takeovers of Australian companies by foreign interests are subject to review and approval by the Treasurer of the Commonwealth of Australia under the Foreign Acquisitions and Takeovers Act 1975. The statute applies to any acquisition or proposed acquisition of 15% or more of the outstanding shares of an Australian company by one foreign person or group of associated foreign persons or any acquisition or proposed acquisition which results in one foreign person or group of associated foreign persons controlling 15% or more of total voting power. In addition, the statute applies to any acquisition or proposed acquisition by non-associated foreign persons resulting in foreign persons controlling, in the aggregate, 40% or more of total voting power or ownership.

Material Contracts

Other than the Executive Service Agreement (incorporated by reference to our registration statement on Form 20-F filed on December 21, 2009), there are no material contracts (other than contracts entered into in the ordinary course of business) to which the Company or any member of the Orbital Group is a party in the two years immediately prior to publication of this document.

Exchange Controls

Under existing Australian legislation, the Reserve Bank of Australia does not prohibit the import and export of funds, and generally no governmental permission is required for Orbital to move funds in and out of Australia. However, for the movement of funds to and from “tax havens”, as specified by current regulations, a tax clearance certificate must be obtained. The United States is not a declared tax haven. Accordingly, at the present time, remittances of any dividends, interest or other payments by Orbital to non-resident holders of Orbital’s securities in the United States are not restricted by exchange controls.

Taxation

The following is a summary of material United States federal income and Australian tax consequences of the ownership of ADSs or ordinary shares by US Holders. Except as otherwise noted, the statements of Australian and United States tax laws set out below are based on the laws in force, as of the date of this Annual Report, and are subject to any changes in United States or Australian law and in the Convention Between the Government of the United States of America and the Government of Australia for the Avoidance of Double Taxation and the Prevention of Fiscal Evation with Respect to Taxes on Income as amended (the “Treaty”), occurring after that date, possibly with retrospective effect.

For purposes of this discussion, a US Holder is any beneficial owner of ADSs or ordinary shares that is:

• a citizen or resident of the United States;

• a corporation organised under the laws of the United States or any state;

• an estate the income of which is subject to United States federal income tax without regard to its source; or

• a trust if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control all substantial decisions of the trust.

Australian Taxation

The following summary outlines the Australian income tax implications to non-resident holders of ADSs and ordinary shares who held ADSs or ordinary shares as capital assets. The summary is not exhaustive of all possible tax considerations, and holders of ADSs and ordinary shares are advised to satisfy themselves as to the overall tax consequences regarding the application of any relevant double taxation convention, by consulting their own tax advisers. The summary is based on legislation and case law applicable at the date of this report. Future legislative changes and developments in case law interpretation may impact upon the taxation position set out below.

- 62 -

Residency

A natural person will be a resident of Australia if that person has been in Australia for more than 183 days in a year of income, unless that person has a usual place of abode outside of Australia and does not intend to take up residency in Australia.

A corporation will be a resident of Australia if it is incorporated in Australia, or if not being incorporated in Australia, carries on business in Australia, and has either its central management and control in Australia, or its voting power is controlled by shareholders who are residents of Australia.

Taxation of Dividends

Dividends paid by an Australian resident corporation may be paid as franked or unfranked dividends. Australian corporations are required to provide shareholders with notices detailing the extent to which dividends are franked or unfranked, and the deduction, if any, of dividend withholding tax. To the extent to which those dividends are paid out of profits which have been subject to Australian company tax, they will be franked dividends. Fully franked dividends paid to a non-resident will be exempt from Australian dividend withholding tax. Unfranked or partially franked dividends will be subject to Australian dividend withholding tax to the extent the dividends are unfranked. The rate of withholding tax on dividends is discussed below.

Shareholders who elect to participate in a dividend reinvestment plan in effect elect to invest their dividends in an allotment of ordinary shares. As is the case with a cash dividend, the receipt of these additional ordinary shares will represent assessable income to an Australian resident shareholder, and will carry franking credits to the same extent as any cash dividend.

The Australian Government provides a taxation incentive in the form of 125% tax deduction for companies which incur expenditure on research and development activities. This incentive has contributed to Orbital’s past level of accumulated carry forward tax losses, which were available for off-set against future income. The availability of these carry forward losses has impacted the amount of tax Orbital has paid and accordingly, the ability of Orbital to pay franked dividends.

Bonus shares issued to existing shareholders out of a share capital account are not dividends for Australian income tax purposes, and are therefore not subject to dividend withholding tax.

Withholding Tax on Dividends

The Treaty limits to 15% the Australian withholding tax on the unfranked portion of a dividend paid by an Australian company to a US Holder who is a resident of the United States for the purposes of the Treaty and who is beneficially entitled to the dividend, unless the recipient carries on business in Australia through a permanent establishment, or performs independent personal services from a fixed base in Australia, and his share holding is effectively connected with the permanent establishment or fixed base, in which case a 30% withholding tax applies. Where a US resident company holds at least 10%, but less than 80%, of the voting power of an Australian company, Australian withholding tax on the unfranked portion of a dividend is chargeable at 5%. No withholding tax is chargeable on dividends paid to a US resident company which is a listed public company from an 80% or more beneficially owned subsidiary. The limitations on the rate of Australian withholding tax chargeable on dividend payments under the Treaty are not applicable in the case of recipients who are not “qualified persons” under the Treaty. Holders of ADSs or ordinary shares should consult their tax advisor as to whether they are “qualified persons” under the Treaty.

A withholding tax exemption is available where a dividend paid by an Australian company is paid out of profits which include certain dividends received from foreign companies.

Capital Gains Tax (“CGT”)

The sale of ADSs and ordinary shares may be subject to Australian CGT where the ADSs or the ordinary shares are held by:

• natural persons or corporations who are residents of Australia;

• non-residents of Australia who, together with their associates, beneficially hold or, at any time during the five years prior to the sale, held 10% or more of the issued capital of Orbital, or options or rights to acquire ADSs or ordinary shares; or

• non-residents and are used in carrying on a trade or business through a permanent establishment in Australia

Australian CGT is generally payable upon the profit arising from the sale of assets acquired after September 19, 1985. For assets that are sold prior to September 21, 1999 the profit is calculated as the disposal proceeds less the costs, indexed for inflation for assets held for at least twelve months. Capital losses are not subject to indexation and can only be offset against capital gains.

- 63 -

For assets that are sold after September 21, 1999 the taxation treatment depends on whether the assets were sold by an individual or a company. Special rules also apply to Australian complying superannuation funds.

For assets that were acquired prior to September 21, 1999 by an individual, and held for at least one year, the individual taxpayer now has a choice of including in assessable income either:

• 50% of the profit on sale; or

• 100% of the difference between the disposal price and the indexed cost base as at September 30, 1999.

For assets acquired on or after September 21, 1999 by an individual, and held for at least one year, the individual will only be taxed on 50% of the difference between the disposal price and the original cost.

For assets that are sold after September 21, 1999, the capital gain is calculated as the disposal proceeds less the costs, indexed for inflation to September 30, 1999 for assets held for at least one year. Companies are not eligible for the 50% discount treatment.

Where the asset is held for less than one year, 100% of the gain will be assessable for both individuals and companies.

Assets acquired before September 19, 1985 generally remain free from tax. Capital losses are not available in respect of assets acquired before this date.

Ordinary shares issued to a shareholder who is a resident for Australian tax purposes, through participation in the dividend reinvestment plan will be deemed to be acquired when issued and will be subject to Australian CGT upon disposal as discussed above, regardless of the date of acquisition of the relevant original shares participating in the plan.

Stamp Duty

No Australian stamp duty will be payable on the issue or stock market transfer of an ADS, provided the ADS is registered on a register kept by or on behalf of the person who issued the ADS in the United States, and the ADS is registered on the register:

• for at least six months before the transfer, or on or before March 14, 1997; or

• since they were issued; and

• the transfer of the ADS must be made by an order lodged with a broker who is a member of the New York or NASDAQ stock exchanges; or

• be solely for the purpose of facilitating settlement of a transfer described above.

From July 1, 2001, no Australian stamp duty is payable on the transfer of Orbital’s ordinary shares.

United States Federal Income Taxation

The following is a summary of the material United States Federal income tax consequences resulting from the ownership and disposition of ADSs or ordinary shares by US Holders. This summary is not exhaustive of all possible tax considerations, and holders of ADSs and ordinary shares are advised to satisfy themselves as to the overall tax consequences by consulting their own tax advisers. This summary applies only to holders who hold ADSs or ordinary shares as capital assets and does not apply to holders of ADSs or ordinary shares that are subject to special rules, such as holders that:

• are generally exempt from United States Federal income tax;

• actually or constructively own ten percent or more of the voting shares of Orbital;

• are dealers in ADSs or ordinary shares;

• are traders in securities that elect to use a mark-to-market method of accounting;

• are banks or life insurance companies;

• acquired ADSs or ordinary shares under employee share plans or otherwise as compensation;

• are liable for alternative minimum tax;

• hold ADSs or ordinary shares as part of a straddle or a hedging or conversion transaction; or

• have a functional currency that is not the US dollar.

- 64 -

This summary is based on the Internal Revenue Code of 1986, as amended (the “Code”), its legislative history, existing and proposed regulations, published rulings and court decisions, as well as the Treaty. These laws are subject to change, possibly on a retrospective basis.

This summary is also based in part on representations of the depositary and assumes that each obligation provided for in or otherwise contemplated by the deposit agreement and any related agreement will be performed in accordance with its terms. Beneficial owners of ADSs or ordinary shares are advised to consult their tax advisers as to the Australian, United States and other tax consequences resulting from the ownership and disposition of ADSs and ordinary shares, including state and local tax consequences.

If a partnership holds the ADSs or ordinary shares, the United States federal income tax treatment of a partner will generally depend on the status of the partner and the tax treatment of the partnership. A partner in a partnership holding the ADSs or ordinary shares should consult its tax advisor with regard to the United States federal income tax treatment of an investment in the ADSs or ordinary shares.

For United States Federal income tax purposes, holders of ADRs evidencing ADSs will generally be treated as owners of the ordinary shares underlying such ADRs. Exchanges of ordinary shares for ADRs, and ADRs for ordinary shares, generally will not be subject to United States federal income tax.

Taxation of Dividends

Under the United States federal income tax laws, and subject to the passive foreign investment company (“PFIC”) rules discussed below, US Holders will include in gross income the gross amount of any dividend paid, before reduction for Australian withholding taxes, by Orbital out of its current or accumulated earnings and profits, as determined for United States federal income tax purposes. Dividends paid to non-corporate US Holders in taxable years beginning before January 1, 2013 that constitute qualified dividend income will be taxable at a maximum rate of 15 percent provided that the US Holder holds the ADSs or ordinary shares for more than 60 days during the 121-day period beginning 60 days before the ex-dividend date and meets other holding period requirements. Dividends paid with respect to the ADSs or ordinary shares generally will be qualified dividend income.

US Holders must include any Australian tax withheld from the dividend payment in this gross amount even though they do not in fact receive it. The dividend is taxable to a US Holder when such US Holder, in the case of ordinary shares, or the depositary, in the case of ADSs, receives the dividend, actually or constructively. The dividend will not be eligible for the dividends-received deduction generally allowed to United States corporations in respect of dividends received from other United States corporations.

The amount of the dividend distribution to be included in income of a US Holder will be the US dollar value of the Australian dollar payments made, determined at the spot Australian dollar/US dollar rate on the date the dividend distribution is includible in the income of the US Holder, regardless of whether the payment is in fact converted into US dollars. Generally, any gain or loss resulting from currency exchange fluctuations during the period from the date the dividend payment is includible in income to the date such payment is converted into US dollars will be treated as ordinary income or loss and will not be eligible for the special tax rate applicable to qualified dividend income. The gain or loss will generally be income or loss from sources within the United States for foreign tax credit limitation purposes. Distributions in excess of current and accumulated earnings and profits, as determined for United States federal income tax purposes, will be treated as a non-taxable return of capital to the extent of the US Holder’s basis in the ADSs or ordinary shares and thereafter as capital gain.

Subject to foreign tax credit limitations, the Australian tax withheld in accordance with the Treaty and paid over to Australia will be creditable against the US Holder’s United States federal income tax liability or, at the US Holders’s election, deductible from the US Holder’s gross income for United States federal income tax purposes. Special rules apply in determining the foreign tax credit limitation with respect to dividends that are subject to the maximum 15 percent tax rate. To the extent a refund of the tax withheld and paid over to Australia is available to a US Holder, the amount of tax withheld is not eligible for credit against such US Holder’s United States federal income tax liability. Dividends will generally be income from sources without the United States. Dividends paid in taxable years beginning after December 31, 2006 will, depending on the US Holder’s circumstances, be “passive” or “general” income which, in either case, is treated separately from other types of income for purposes of computing the foreign tax credit allowable to US Holders.

It is possible that Orbital is or will be at least 50% owned by persons treated as United States persons under the Code. Under Section 904(h) of the Code, dividends paid by a non-U.S. corporation that is at least 50% owned by United States persons may be treated as income derived from sources within the United States rather than from sources without the United States for foreign tax credit purposes to the extent the non-US corporation has more than an insignificant amount of income from sources within the United States. The effect of this rule, if applicable in future years, may be to treat a portion of the dividends paid by Orbital as income derived from sources within the United States for foreign tax credit purposes. Such treatment may adversely affect a shareholder’s ability to use foreign tax credits.

- 65 -

Distributions of additional ordinary shares to US Holders with respect to their ADSs or ordinary shares that are made as part of a pro rata distribution to all shareholders of Orbital will generally not be subject to United States federal income tax.

US Holders of ADSs or ordinary shares that elect, under either the bonus share election plan or the dividend reinvestment plan, to receive additional ordinary shares at a discount rather than cash dividends will be treated for United States Federal income tax purposes as having received a dividend equal to the fair market value of the additional ordinary shares received.

Taxation of Capital Gains

Subject to the PFIC rules discussed below, upon a sale or other disposition of ADSs or ordinary shares, a US Holder will recognize capital gain or loss for United States federal income tax purposes equal to the difference between the US dollar value of the amount realized and the US Holder’s tax basis, determined in US dollars, in the ADSs or ordinary shares sold or otherwise disposed of. Capital gain of a noncorporate US Holder is generally taxed at preferential rates where the holder has a holding period greater than one year. The gain or loss will generally be income or loss from sources within the United States for foreign tax credit limitation purposes.

Passive Foreign Investment Company Rules

Orbital believes that the ADSs and ordinary shares should not be treated as stock of a PFIC for United States federal income tax purposes, but this conclusion is a factual determination made annually and thus may be subject to change. If Orbital were to be treated as a PFIC, unless a US Holder elects to be taxed annually on a mark-to-market basis with respect to the ADSs or ordinary shares, gain realized on the sale or other disposition of ADSs or ordinary shares would in general not be treated as capital gain. The US Holder would be treated as if such holder had realized such gain and certain “excess distributions” ratably over the holder’s holding period for the ADSs or ordinary shares and would be taxed at the highest tax rate in effect for each such year to which the gain was allocated, together with an interest charge in respect of the tax attributable to each such year. With certain exceptions, ADSs or ordinary shares will be treated as stock of a PFIC if Orbital was a PFIC at any time during the US Holder’s holding period in the ADSs or ordinary shares. Dividends that a US Holder receives from Orbital will not be eligible for the special tax rates applicable to qualified dividend income if Orbital is treated as a PFIC with respect to a US Holder either in the taxable year of the distribution or the preceding taxable year, but instead will be taxable at rates applicable to ordinary income.

ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Exposures

We are exposed to market risks, including changes in interest rates, changes in foreign currency exchange rates, and credit risk. To manage the volatility relating to these risks, we take advantage of natural offsets to the extent possible. For example, whenever possible we have cash expenses in the same countries and currencies as we generate our cash flows. In appropriate circumstances, and where we are unable to naturally offset our exposure to these risks, we enter into derivative transactions to synthetically reduce the exposures. The purpose of these hedging instruments is to create a corresponding, but opposite, movement in the underlying value of the cash flow being hedged. We enter into these transactions only in accordance with internal policies set by our directors. We do not hold or enter into derivative financial instruments for trading purposes.

A summary of market risk factors is generally discussed below. For additional quantitative and qualitative information about these market risks, refer to note 4 “Financial Risk Managements Objectives and Policies” in our audited consolidated financial statements.

Interest rate risk

The Group’s exposure to market interest rates relates primarily to the Group’s cash and cash equivalents on deposit with Australian banks.

The primary goal of the Group is to maximize returns on surplus cash, using deposits with maturities of less than 90 days. Management continually monitors the returns on funds invested. The Group also had a term deposit of greater than 90 days and less than 365 days that had been pledged as security to the Group’s bankers for a trade finance facility.

Foreign currency risk

As a result of the investment in Synerject LLC, an associate, the Group’s statement of financial position can be affected significantly by movements in the US$/A$ exchange rates.

The Group also has transactional currency exposures. Such exposure arises from sales or purchases by an operating entity in currencies other than the functional currency.

Approximately 20% of the Group’s sales are denominated in currencies other than the functional currency of the operating entity making the sale, whilst approximately 14% of costs are denominated in currencies other than the functional currency of the operating entity making the expenditure.

With respect to assets and liabilities denominated in foreign currencies, the Group ensures that its net exposure is kept to an acceptable level by buying or selling foreign currencies at spot rates when necessary. The Group does not hold foreign currency positions for trading purposes.

Credit risk

Credit risk arises from the financial assets of the Group, which comprise cash and cash equivalents and trade and other receivables. The Group’s exposure to credit risk arises from potential default of the counter party, with a maximum exposure equal to the carrying amount of these instruments.

The Group does not hold any credit derivatives to offset its credit exposure, however the Group does hold receivable insurance where appropriate.

It is the Group’s policy that all customers who wish to trade on credit terms are subject to credit verification procedures including an assessment of their independent credit rating, financial position, past experience and industry reputation. Risk limits are set for each individual customer in accordance with parameters set by management. These risk limits are regularly monitored.

In addition, receivable balances are monitored on an ongoing basis.

There are no significant concentrations of credit risk within the Group and financial instruments are only invested with a major financial institution to minimise the risk of default of counterparties.

- 67 -

Liquidity risk

The Group established a trade finance facility with its bankers during fiscal 2010. The Group’s does not have any other bank overdrafts, bank loans, preference shares, finance leases or committed available credit lines as at June 30, 2011.

The only external borrowing of the Group are the trade finance facility repayable on terms not exceeding 180 days and the interest free Western Australian Government loan of $14.3 million repayable in installments commencing in May 2010.

ITEM 15. CONTROLS AND PROCEDURES

(a) Disclosure Controls and Procedures:

Orbital has carried out an evaluation, under the supervision and with the participation of management, including the Chief Executive Officer and Chief Financial Officer of Orbital, of the effectiveness of the design and operation of Orbital’s disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) as of the end of the period covered by this annual report. Based upon that evaluation, Orbital’s Chief Executive Officer and Chief Financial Officer concluded that, as of June 30, 2011, Orbital’s disclosure controls and procedures were effective.

(b) Management’s Report on Internal Control Over Financial Reporting:

Orbital’s management is responsible for establishing and maintaining adequate internal control over financial reporting. The Securities Exchange Act of 1934 defines internal control over financial reporting in Rule 13a-15(f) and 15d-15(f) as a process designed by, or under the supervision of, the company’s principal executive and principal financial officers and effected by the company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

• pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company;

• provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and

• �� provide reasonable assurance regarding prevention or timely detection of unauthorised acquisition, use or disposition of the company’s assets that could have a material effect on the consolidated financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

- 70 -

Orbital’s management assessed the effectiveness of its internal control over financial reporting as of June 30, 2011. In making this assessment, Orbital’s management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO, in Internal Control-Integrated Framework. Based upon its assessment, Orbital’s management concluded that, as of June 30, 2011, its internal control over financial reporting is effective based upon those criteria.

(c) Attestation Report of the Registered Public Accounting Firm:

The Group is a non-accelerated filer and as such Ernst & Young, an Independent Registered Public Accounting Firm that audited the Fiscal 2011 consolidated financial statements included in this annual report on Form 20-F, is not required to issue an Attestation Report for Fiscal 2011.

(d) Changes in Internal Control Over Financial Reporting:

There have been no significant changes in the Company’s internal controls or in other factors that could significantly affect these controls subsequent to the Evaluation Date.

Pre-approval Policies and Procedures

Orbital’s Audit Committee has adopted policies and procedures for the pre-approval of permitted services provided by the Company’s auditors, Ernst & Young. Prior to the commencement of each financial year the Company’s chief financial officer and its auditors submit to the Audit Committee a schedule of the types of services that are expected to be performed during the following year for its approval. Pre-approval of an audit or non-audit service may be given as a general pre-approval, as part of the Audit Committee’s approval of the scope of the engagement of the auditor or on an individual basis. The policy prohibits retaining the auditor to perform the prohibited non-audit functions as defined for the purposes of section 201 of the Sarbanes-Oxley Act.

“Four-stroke”	A “four-stroke cycle” or sometimes called the “Otto cycle”. A type of internal combustion engine operating cycle requiring two full engine revolutions (two up and two down piston movements) per combustion event in an engine.
“Fuel Rail Assembly”	The fuel rail assembly is an assembly, typically a cast modular, or extruded assembly that houses the fuel injector, interfaces the fuel injector to the air injector and provides fuel and air services to the injectors. Frequently the air and fuel regulators will be incorporated into the fuel rail assembly.
“Horsepower”	A unit of measure of power in the U.S. and Imperial system. The metric equivalent of horsepower is Kilowatt. One Kilowatt is equivalent to 1.34hp.
“FlexDiTM”	A general term to describe the fuel injection and combustion process developed and marketed by Orbital.

“Stoichiometric”	The chemically correct or theoretical proportions of reactants (fuel and air) in order for complete combustion to occur. Complete combustion is a process which burns all the carbon (C) to (CO2), all hydrogen (H) to (H2O) and all sulphur (S) to (SO2). If there are unburned components in the exhaust gas such as C, H2, CO the combustion process is uncompleted
“Two-stroke”	In full, a “two-stroke cycle”. A type of internal combustion engine operating cycle requiring one full engine revolution (one up and one down piston movement) per combustion event in an engine.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders of Orbital Corporation Limited

We have audited the accompanying consolidated statements of financial position of Orbital Corporation Limited and subsidiaries (the “Company”) as of June 30, 2011 and 2010, and the related consolidated income statements, consolidated statements of comprehensive income, consolidated statements of changes in equity and consolidated statements of cash flows for each of three years in the period ended June 30, 2011. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We did not audit the financial statements of Synerject LLC (“Synerject”), a significant investee of the Company which is accounted for by use of the equity method (see note 16 to the consolidated financial statements), for the year ended June 30, 2009. The Company’s share of profit of Synerject was A$1,846,000 for the year ended June 30, 2009. Those statements were prepared in accordance with accounting principles generally accepted in the United States of America and were audited by other auditors whose report has been furnished to us, and our opinion, insofar as it relates to the amounts included for Synerject, on the basis of accounting principles generally accepted in the United States of America, for the year ended June 30, 2009, is based solely on the report of the other auditors. We have applied auditing procedures to the adjustments to reflect the Company’s share of profit of Synerject in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit the Company’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits and, for 2009, the report of other auditors provide a reasonable basis for our opinion.

In our opinion, based on our audits and, for 2009, the report of other auditors, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Orbital Corporation Limited and subsidiaries at June 30, 2011 and 2010, and the consolidated results of their operations and their cash flows for each of the three years in the period ended June 30, 2011 in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board.

NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2011

1.REPORTING ENTITY

Orbital Corporation Limited (the “Company”) is a company domiciled in Australia. The address of the Company’s registered office is 4 Whipple Street, Balcatta, Western Australia. The consolidated financial report of the Company for the year ended 30 June 2011 comprises the Company and its subsidiaries (together referred to as the “Group”).

The consolidated financial report was authorised for issue by the directors on 31 October 2011.

2.BASIS OF PREPARATION

(a)Statement of Compliance

The financial report complies with Australian Accounting Standards as issued by the Australian Accounting Standards Board and International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board.

(b)Basis of Measurement

The consolidated financial statements have been prepared on the historical cost basis, except for contingent consideration which is measured at fair value.

(c)Functional and Presentation Currency

These consolidated financial statements are presented in Australian dollars, which is the Company’s functional currency and the functional currency of the majority of the Group.

The Company is of a kind referred to in ASIC Class Order 98/100 dated 10 July 1998 and in accordance with that Class Order, all financial information presented in Australian dollars has been rounded to the nearest thousand unless otherwise stated.

(d)Use of Estimates and Judgements

The preparation of financial statements requires management to make judgements, estimates and assumptions that affect the application of accounting policies and reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates.

Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised if the revision affects only that period, or in the period of the revision and future periods if the revision affects both current and future periods.

Judgements made by management in the application of International Financial Reporting Standards that have a significant effect on the financial report and estimates with a significant risk of material adjustment in the next year are discussed in note 5.

3.SIGNIFICANT ACCOUNTING POLICIES

(a)New Accounting Standards and Interpretations

The accounting policies adopted are consistent with those of the previous financial year. From 1 July 2010, the Group has adopted all the standards and interpretations mandatory for annual periods beginning on or after 1 July 2010. Adoption of these standards and interpretations did not have any effect on the financial position or performance of the Group. The Group has not elected to early adopt any new standards or amendments.

(b)Basis of Consolidation

(i) Subsidiaries

Subsidiaries are all those entities over which the Group has the power to govern the financial and operating policies so as to obtain benefits from their activities. The existence and effect of potential voting rights that are currently exercisable or convertible are considered when assessing whether a group controls another entity.

The financial statements of the subsidiaries are prepared for the same reporting period as the parent company, using consistent accounting policies. In preparing the consolidated financial statements, all intercompany balances and transactions, income and expenses and profit and losses resulting from intragroup transactions have been eliminated in full.

F-9

NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2011

3. SIGNIFICANT ACCOUNTING POLICIES (continued)

(b) Basis of Consolidation (continued)

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 acquisition of subsidiaries is accounted for using the acquisition method of accounting. The acquisition method of accounting involves recognising at acquisition date, separately from goodwill, the identifiable assets acquired, the liabilities assumed and any non-controlling interest in the acquiree. The identifiable assets acquired and the liabilities assumed are measured at their acquisition date fair values.

The difference between the above items and the fair value of the consideration (including the fair value of any pre-existing investment in the acquiree) is goodwill or a discount on acquisition.

A change in the ownership interest of a subsidiary that does not result in a loss of control, is accounted for as an equity transaction.

If the Group loses control over a subsidiary, it

• Derecognises the assets (including goodwill) and liabilities of the subsidiary.

• Derecognises the carrying amount of any non-controlling interest.

• Derecognises the cumulative translation differences, recorded in equity.

• Recognises the fair value of the consideration received.

• Recognises the fair value of any investment retained.

• Recognises any surplus or deficit in profit or loss.

• Reclassifies the parent’s share of components previously recognised in other comprehensive income to profit or loss.

(ii) Associate

The Group’s investment in its associate is accounted for using the equity method of accounting in the consolidated financial statements. The associate is an entity over which the Group has significant influence and that is neither a subsidiary nor a joint venture.

The Group generally deems they have significant influence if they have over 20% of the voting rights.

Under the equity method, investments in associates are carried in the consolidated statement of financial position at cost plus post-acquisition changes in the Group’s share of net assets of the associate. Goodwill relating to an associate is included in the carrying amount of the investment and is not amortised. After application of the equity method, the Group determines whether it is necessary to recognise any impairment loss with respect to the Group’s net investment in associates.

The Group’s share of its associates’ post-acquisition profit or losses is recognised in the income statement, and its share of post-acquisition movements in reserves is recognised in reserves. The cumulative post-acquisition movements are adjusted against the carrying amount of the investment. Dividends received from the associate reduce the carrying amount of the investment.

When the Group’s share of losses in the associate equals or exceeds its interest in the associate, including any unsecured long-term receivables or loans, the Group does not recognise further losses, unless it has incurred obligations or made payments on behalf of the associate.

The associate’s accounting policies conform to those used by the Group for like transactions and events in similar circumstances.

(iii) Transactions Eliminated on Consolidation

Intra-group balances, and any unrealised gains and losses or income and expenses arising from intra-group transactions, are eliminated in preparing the consolidated financial statements. Unrealised gains arising from transactions with associates are eliminated to the extent of the Group’s interest in the entity with adjustments made to the investment in the associate. Unrealised losses are eliminated in the same way as unrealised gains, but only to the extent that there is no evidence of impairment. Gains and losses are recognised as the contributed assets are consumed or sold or, if not consumed or sold, when the Group’s interest in such entities is disposed of.

F-10

NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2011

3. SIGNIFICANT ACCOUNTING POLICIES (continued)

(c)Foreign Currency

(i) Foreign currency transactions

Transactions in foreign currencies are converted to the respective functional currencies of Group entities at exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies at the reporting date (except those representing the Group’s net investment in subsidiaries and its associate – see below) are retranslated to the functional currency at the exchange rate at that date. Foreign exchange differences arising on translation are recognised in the income statement. Non-monetary assets and liabilities that are measured in terms of historical cost in a foreign currency are translated using the exchange rate at the date of the transaction.

(ii) Financial statements of foreign operations

The assets and liabilities of foreign operations are translated to Australian dollars at exchange rates ruling at the reporting date. The revenues and expenses of foreign operations are translated to Australian dollars at rates approximating the exchange rates ruling at the dates of the transactions. Foreign exchange differences arising on retranslation are recognised directly in a separate component of equity described as ‘foreign currency translation reserve’.

(iii) Net investment in foreign operations

Exchange differences arising from the translation of balances representing the net investment in foreign operations are taken to the foreign currency translation reserve. They are released into the income statement upon disposal.

(d)Financial Instruments

(i) Non-derivative financial instruments

Non-derivative financial instruments comprise trade and other receivables, cash and cash equivalents, loans and borrowings, and trade and other payables.

Non-derivative financial instruments are recognised initially at fair value plus, for instruments not at fair value through profit or loss, any directly attributable transaction costs. Subsequent to initial recognition non-derivative financial instruments are measured as described below.

A financial instrument is recognised if the Group becomes party to the contractual provisions of the instrument. Financial assets are derecognised if the Group’s contractual rights to the cash flows from the financial asset expire or if the Group transfers the financial asset to another party without retaining control or substantially all risks and rewards of the asset. Regular way purchases and sales of financial assets are accounted for at trade date, i.e., the date that the Group commits itself to purchase or sell the asset. Financial liabilities are derecognised if the Group’s obligations specified in the contract expire or are discharged or cancelled.

Cash and cash equivalents - refer note 12

Cash and cash equivalents comprise cash balances, at call deposits and bank-endorsed bills of exchange at discounted value.

Other financial assets - refer note 13

Other financial assets comprise term deposits with financial institutions with maturities between 90 days and 365 days. Subsequent to initial recognition other financial assets are stated at amortised cost.

Trade and other receivables - refer note 14

Subsequent to initial recognition, trade receivables are stated at their amortised cost, less impairment losses. Normal settlement terms are 30 to 60 days. The collectability of debts is assessed at balance date and specific allowance is made for any doubtful accounts. Individual debts that are known to be uncollectible are written off when identified. An impairment allowance is recognised when there is objective evidence that the Group will not be able to collect the receivable. Financial difficulties of the debtor, default payments or debts more than 60 days overdue are considered objective evidence of impairment. The amount of the impairment loss is the receivable carrying amount compared to the present value of estimated future cash flows, discounted at the original effective interest rate.

F-11

NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2011

3. SIGNIFICANT ACCOUNTING POLICIES (continued)

(d) Financial Instruments (continued)

Trade and other liabilities - refer note 20

Liabilities are recognised for amounts due to be paid in the future for goods or services received. Subsequent to initial recognition, trade and other payables are stated at their amortised cost.

Trade payables are non-interest bearing and are normally settled on 30-day terms.

Interest bearing borrowings - refer note 21

Included in current liabilities is an amount owing under a trade finance facility utilised for the import of inventory. The trade finance facility provides loans of up to 180 days with interest payable at maturity. The loans are initially recognised at the fair value of consideration received plus transaction costs and subsequently stated at amortised cost with any difference between cost and repayment value being recognised in the income statement over the period of the borrowings on an effective interest basis.

Long term borrowings - refer note 26

Included in non-current liabilities is an amount owing to the Government of Western Australia resulting from a loan of $14,346,164 restructured in January 2010. The loan is interest-free with annual repayments commencing in May 2010 and concluding in May 2025.

The non-interest bearing loan from the Government of Western Australia was recognised initially at fair value and subsequently stated at amortised cost using the effective interest method. The difference between the fair value and face value of the loan is accounted for as a government grant as disclosed in note 26.

Contingent consideration - refer note 28

Included in non-current liabilities is an amount owing to the owners of the non-controlling interest in Sprint Gas (Aust) Pty Ltd. The contingent consideration was recognised initially at fair value and subsequently at fair value through profit and loss.

(ii) Derivative financial instruments

The Group may use derivative financial instruments to hedge its exposure to foreign exchange fluctuations and interest rate movements. In accordance with its treasury policy, the Group entity does not hold the derivative financial instruments for trading purposes. However, derivatives that do not qualify for hedge accounting are accounted for as trading instruments.

Derivative financial instruments are recognised initially at fair value. Subsequent to initial recognition, derivative financial instruments are stated at fair value. Changes in the fair value of the derivative financial instrument that are not designated as cash flow hedging instruments are recognised in profit or loss.

Cash flow hedges

Changes in the fair value of the derivative hedging instrument designated as a cash flow hedge are recognised directly in equity to the extent that the hedge is effective. To the extent that the hedge is ineffective, changes in fair value are recognised in profit or loss.

If the hedging instrument no longer meets the criteria for hedge accounting, expires or is sold, terminated or exercised, then hedge accounting is discontinued prospectively. The cumulative gain or loss previously recognised in equity remains there until the forecast transaction occurs. When the hedged item is a non-financial asset, the amount recognised in equity is transferred to the carrying amount of the asset when it is recognised. In other cases the amount recognised in equity is transferred to profit or loss in the same period that the hedged item affects profit or loss.

(e)Inventories - refer note 15

Inventories are carried at the lower of cost and net realisable value. Cost is based on the first-in first-out principle and includes expenditure incurred in acquiring the inventories and bringing them to their present location and condition. Net realisable value is the estimated selling price in the ordinary course of business, less the estimated costs of completion and selling expenses.

F-12

NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2011

3. SIGNIFICANT ACCOUNTING POLICIES (continued)

(f)Property, Plant and Equipment - refer note 18

(i) Recognition and measurement

Items of property, plant and equipment are stated at cost less accumulated depreciation and impairment losses.

Cost includes expenditures that are directly attributable to the acquisition of the asset.

(ii) Subsequent costs

The cost of replacing part of an item of property, plant and equipment is recognised in the carrying amount of the item if it is probable that the future economic benefits embodied within the part will flow to the Group and its cost can be measured reliably. The costs of day-to-day servicing of property, plant and equipment are recognised in profit or loss as incurred.

(iii) Depreciation and Amortisation

Items of property, plant and equipment, including buildings but excluding freehold land, are depreciated/amortised on a straight line basis over their estimated useful lives. The depreciation rates used in the current and comparative period for each class of asset are as follows: Buildings 2.5%; Plant and Equipment 6.67% to 33.3%. Assets are depreciated or amortised from the date of acquisition.

The residual value, the useful life and the depreciation method applied to an asset are reassessed at least annually.

(iv) Asset Sales

The net profit or loss from asset sales are included as other income or expenses of the Group. The profit or loss on disposal of assets is brought to account at the date that an unconditional contract of sale is signed. The profit or loss on disposal is calculated as the difference between the carrying amount of the asset at the time of disposal and the net proceeds on disposal.

(g)Intangibles and goodwill - refer note 19

(i) Research and Development

Expenditure on research activities, undertaken with the prospect of gaining new scientific or technical knowledge and understanding, is recognised in the income statement as an expense as incurred.

Expenditure on development activities, whereby research findings are applied to a plan or design for the production of new or substantially improved products and processes, is capitalised if the product or process is technically and commercially feasible and the Group has sufficient resources to complete development.

Expenditure on intangibles which may be capitalised includes the cost of materials and direct labour. Other development expenditure is recognised in the income statement as an expense as incurred. Capitalised expenditure is stated at cost less accumulated amortisation and impairment losses. Amortisation is charged to the income statement on a straight-line basis over the estimated useful lives of intangible assets unless such lives are indefinite.

(ii) Patents, Licences and Technologies

Patents, licences and technology development and maintenance costs, not qualifying for capitalisation, are expensed as incurred.

(iii) Goodwill

Goodwill acquired in a business combination is initially measured at cost being the excess of the cost of the business combination over the Group’s interest in the net fair value of the acquiree’s identifiable assets, liabilities and contingent liabilities.

Following initial recognition, goodwill is measured at cost less any accumulated impairment losses.

For the purpose of impairment testing, goodwill acquired in a business combination is, from the acquisition date, allocated to each of the Group’s cash-generating units, or groups of cash-generating units, that are expected to benefit from the synergies of the combination, irrespective of whether other assets or liabilities of the Group are assigned to those units or groups of units.

3. SIGNIFICANT ACCOUNTING POLICIES (continued)

(g) Intangibles and goodwill - refer note 19 (continued)

Impairment is determined by assessing the recoverable amount of the cash-generating unit (group of cash-generating units), to which the goodwill relates.

When the recoverable amount of the cash-generating unit (group of cash-generating units) is less than the carrying amount, an impairment loss is recognised. When goodwill forms part of a cash-generating unit (group of cash-generating units) and an operation within that unit is disposed of, the goodwill associated with the operation disposed of is included in the carrying amount of the operation when determining the gain or loss on disposal of the operation. Goodwill disposed of in this manner is measured based on the relative values of the operation disposed of and the portion of the cash-generating unit retained. Impairment losses recognised for goodwill are not subsequently reversed.

(h)Impairment

(i) Financial assets

A financial asset is considered to be impaired if objective evidence indicates that one or more events have had a negative effect on the estimated future cash flows of that asset.

An impairment loss in respect of a financial asset measured at amortised cost is calculated as the difference between its carrying amount, and the present value of the estimated future cash flows discounted at the original effective interest rate. An impairment loss in respect of an available-for-sale financial asset is calculated by reference to its current fair value.

Individually significant financial assets are tested for impairment on an individual basis. The remaining financial assets are assessed collectively in groups that share similar credit risk characteristics.

All impairment losses are recognised in profit or loss. Any cumulative loss in respect of an available-for-sale financial asset recognised previously in equity is transferred to profit or loss.

An impairment loss is reversed if the reversal can be related objectively to an event occurring after the impairment loss was recognised. For financial assets measured at amortised cost and available-for-sale financial assets that are debt securities, the reversal is recognised in profit or loss. For available-for-sale financial assets that are equity securities, the reversal is recognised directly in equity.

(ii) Non-financial assets

The carrying amounts of the Group’s non-financial assets, other than inventories and deferred tax assets, are reviewed at each reporting date to determine whether there is any indication of impairment. If any such indication exists then the asset’s recoverable amount is estimated.

An impairment loss is recognised if the carrying amount of an asset or its cash-generating unit exceeds its recoverable amount. A cash-generating unit is the smallest identifiable asset group that generates cash flows that largely are independent from other assets and groups. Impairment losses are recognised in profit or loss. Impairment losses recognised in respect of cash-generating units are allocated first to reduce the carrying amount of any goodwill allocated to the units and then to reduce the carrying amount of the other assets in the unit (group of units) on a pro rata basis.

The recoverable amount of an asset or cash-generating unit is the greater of its value in use and its fair value less costs to sell. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset.

An impairment loss in respect of goodwill is not reversed. In respect of other assets, impairment losses recognised in prior periods are assessed at each reporting date for any indications that the loss has decreased or no longer exists. An impairment loss is reversed if there has been a change in estimates used to determine the recoverable amount. An impairment loss is reversed only to the extent that the asset’s carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortisation, if no impairment loss had been recognised.

(iii) Goodwill

Impairment is determined by assessing the recoverable amount of the cash-generating unit (group of cash-generating units), to which the goodwill relates.

(i)Share capital - refer note 29

(i) Issued Capital

Share capital is recognised at the fair value of the consideration received.

(ii) Dividends

Dividends are recognised as a liability in the period in which they are declared.

(iii) Transaction Costs

Transaction costs of an equity transaction are accounted for as a deduction from equity, net of any related income tax benefit.

(j)Employee Benefits

(i) Short-term benefits - refer note 23

The provisions for employee entitlements to wages, salaries and annual leave due to be settled within 12 months of year end represent present obligations resulting from employees’ services provided up to the balance date, calculated at undiscounted amounts based on wage and salary rates that the Group expects to pay as at the reporting date including related on-costs, such as workers’ compensation and payroll tax. Expenses for non-accumulating sick leave are recognised when the leave is taken and are measured at the rates paid or payable.

(ii) Long Service Leave - refer note 23

The provision for employee entitlements to long service leave represents the present value of the estimated future cash outflows to be made resulting from employees’ services provided up to balance sheet date.

The provision is calculated using estimated future increases in wage and salary rates including related on-costs and expected settlement dates based on the Group’s experience with staff departures and is discounted using the rates attached to national government securities at balance sheet date, which most closely match the terms of maturity of the related liabilities.

(iii) Defined Contribution Superannuation Fund - refer note 37

Obligations for contributions to the defined contribution superannuation fund are recognised as an expense in the income statement as incurred.

(iv) Share-based payment transactions - refer note 36

Employees have been offered the right to take up shares in the Company under three plans (i) the Employee Share Plan No.1 provides $1,000 of shares per annum and is subject to qualification by length of service, (ii) the Executive Long Term Share Plan (“ELTSP”) is subject to qualification by length of service and achievement of corporate performance targets related to returns to shareholders, and (iii) the Performance Rights Plan is subject to qualification by length of service and achievement of share price targets.

The fair value of rights granted to employees is recognised as an employee benefit expense with a corresponding increase in equity. The fair value of the shares granted under the Employee Share Plan No.1 is based on the market price of the shares on the date of issue. The fair value of the ELTSP is measured at grant date taking into account market performance conditions only, and spread over the vesting period during which the employees become unconditionally entitled to the performance–based shares. The fair value of the shares granted is measured using a Monte-Carlo simulation model. The amount recognised as an expense is adjusted to reflect the actual number of shares that vest except where forfeiture is only due to market conditions that are not met. The fair value of the Performance Rights is measured at grant date taking into account the share price targets and spread over the expected life of the rights.

3. SIGNIFICANT ACCOUNTING POLICIES (continued)

(k)Provisions - Warranties - refer note 25

A provision is recognised if, as a result of a past event, the Group has a present legal or constructive obligation that can be estimated reliably, and it is probable that an outflow of economic benefits will be required to settle the obligation. Provisions are determined by discounting the expected future cash flows at a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the liability.

Provision for warranty is recognised when the underlying products are sold. The provision is based on historical claim data.

(l)Revenue Recognition

Revenues are recognised and measured at the fair value of the consideration received net of the amount of goods and services tax (GST). Exchanges of goods or services of the same nature and value without any cash consideration are not recognised as revenues.

(i) Revenue from Rendering of Services

Revenue from services rendered is recognised in the income statement in proportion to the stage of completion of the transaction at the reporting date. The stage of completion is assessed by reference to the extent of work performed. No revenue is recognised if there are significant uncertainties regarding recovery of the consideration due.

Revenue received in advance represents cash payments received from customers in accordance with contractual commitments prior to the performance of the service.

(ii) Sale of goods

Revenue from the sale of goods is recognised when there is persuasive evidence, usually in the form of an executed sales agreement at the time of delivery of the goods to customer, indicating that there has been a transfer of risks and rewards to the customer, no further work or processing is required, the quantity and quality of the goods has been determined, the price is fixed and generally title has passed.

(iii) Licence and royalties

Revenue earned under various licence, royalty and other agreements is recognised on an accrual basis upon the satisfactory completion of contracted technical specifications. Additional revenue may be earned after a fixed time interval or after delivery of a prototype engine and/or hardware meeting specified performance targets, provided the licence agreements are not terminated. Under the terms of the licence agreements, licensees are not specifically obliged to commence production and sale of engines using Orbital Combustion Process Technology and may terminate the agreements upon notice to Orbital. If a licensee were to terminate its licence agreement with Orbital, the licensee would forfeit the licence and any technical disclosure fees paid through to the date of termination. Revenue under royalty agreements is recognised when such amounts become due and payable.

(iv) Interest Revenue

Revenue is recognised as interest accrues using the effective interest method.

(v) Dividends

Revenue is recognised when the Group’s right to receive the payment is established.

(m)Operating leases

Payments made under operating leases are recognised in the income statement on a straight-line basis over the term of the lease.

(n)Finance expense

Borrowing costs directly attributable to the acquisition, construction or production of a qualifying asset (i.e. an asset that necessarily takes a substantial period of time to get ready for its intended use or sale) are capitalised as part of the cost of that asset. All other borrowing costs are expensed in the period they occur.

Borrowing costs consist of interest and other costs that an entity incurs in connection with the borrowing of funds

(o)Income Tax - refer note 10

(i) Current income tax expense and liability

Income tax on the profit or loss for the year presented comprises current and deferred tax. Income tax is recognised in the income statement except to the extent that it relates to items recognised directly in equity, in which case it is recognised in equity.

Current tax is the expected tax payable on the taxable income for the year, using tax rates enacted or substantially enacted at the balance sheet date, and any adjustment to tax payable in respect of previous years.

(ii) Deferred income tax expense and liability

Deferred tax is provided using the balance sheet liability method, providing for temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. The amount of deferred tax provided is based on the expected manner of realisation or settlement of the carrying amount of assets and liabilities, using tax rates enacted or substantively enacted at the balance sheet date.

A deferred tax asset is recognised only to the extent that it is probable that future taxable profits will be available against which the asset can be utilised. Deferred tax assets are reduced to the extent that it is no longer probable that the related tax benefit will be realised.

(iii) Tax Consolidation

The Company and its wholly-owned Australian resident entities have formed a tax-consolidated group with effect from 1 July 2002 and are therefore taxed as a single entity from that date. The head entity within the tax-consolidated group is Orbital Corporation Limited.

(p)Operating segments - refer note 6

An operating segment is a component of an entity that engages in business activities from which it may earn revenues and incur expenses (including revenues and expenses relating to transactions with other components of the same entity), whose operating results are regularly reviewed by the entity’s executive management team (the chief operating decision maker) to make decisions about resources to be allocated to the segment and assess its performance and for which discrete financial information is available. Management will also consider other factors in determining operating segments such as the existence of a line manager and the level of segment information presented to the executive management team.

The group aggregates two or more operating segments when they have similar economic characteristics, and the segments are similar in each of the following respects:

• Nature of the products and services,

• Nature of the production processes,

• Type or class of customer for the products and services,

• Methods used to distribute the products or provide the services, and if applicable,

• Nature of the regulatory environment.

Operating segments that meet the quantitative criteria as prescribed by IFRS 8 are reported separately. However, an operating segment that does not meet the quantitative criteria is still reported separately where information about the segment would be useful to users of the financial statements.

Information about other business activities and operating segments that are below the quantitative criteria are combined and disclosed in a separate category for “all other segments”.

3. STATEMENT OF SIGNIFICANT ACCOUNTING POLICIES (continued)

(q)Goods and services tax

Revenue, expenses and assets are recognised net of the amount of goods and services tax (GST), except where the amount of GST incurred is not recoverable from the taxation authority. In these circumstances, the GST is recognised as part of the cost of acquisition of the asset or as part of the expense.

Receivables and payables are stated with the amounts of GST included. The net amount of GST recoverable from, or payable to, the Australian Taxation Office is included as a current asset or liability in the statement of financial position.

Cash flows are included in the statement of cash flows on a gross basis. The GST components of cash flows arising from investing and financing activities which are recoverable from, or payable to, the Australian Taxation Office are classified as operating cash flows.

(r)Earnings per share - refer note 11

The Group presents basic and diluted earnings per share (EPS) data for its ordinary shares. Basic EPS is calculated by dividing the profit or loss attributable to ordinary shareholders of the Company by the weighted average number of ordinary shares outstanding during the period.

Diluted EPS is determined by adjusting the profit or loss attributable to ordinary shareholders and the weighted average number of ordinary shares outstanding for the effects of all dilutive potential ordinary shares.

(s)Government grants - refer note 27

Government grants are recognised in the Statement of Financial Position as a liability when the grant is received. Government grants are recognised as income over the periods necessary to match them with the related costs which they are intended to compensate, on a systematic basis. Government grants received on compensation for expenses and losses already incurred or for the purpose of giving immediate financial support are recognised immediately in profit and loss for the period.

When the grant relates to a discount on services to be rendered in the future, the fair value is credited to deferred revenue and is released to the income statement over the periods that the discounted services are rendered.

When the grant relates to an asset (investment grants relating to the construction of a heavy duty engine test facility), the fair value is credited to deferred income and is released to the income statement over the expected useful life of the relevant asset by equal annual instalments.

(t)Business combination - refer note 38

Business combinations are accounted for using the acquisition method. The consideration transferred in a business combination shall be measured at fair value, which shall be calculated as the sum of the acquisition date fair values of the assets transferred by the acquirer, the liabilities incurred by the acquirer to former owners of the acquiree and the equity issued by the acquirer, and the amount of any non-controlling interest in the acquiree. For each business combination, the acquirer 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-related costs are expensed as incurred, 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 to fair value 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 139 either in profit or loss or as a change to other comprehensive income. If the contingent consideration is classified as equity, it should not be remeasured until it is finally settled within equity

(u)New standards and interpretations not yet effective

The following standards, amendments to standards and interpretations have been identified as those which may impact the entity in the period of initial application. They are available for early adoption at 30 June 2011, but have not been applied in preparing this financial report:

Reference	Title	Summary	Application date of standard	Application date for Group
AASB 9 (IFRS 9)	Financial Instruments	AASB 9 (IFRS 9) includes requirements for the classification and measurement of financial assets resulting from the first part of Phase 1 of the IASB’s project to replace IAS 39Financial Instruments: Recognition and Measurement(AASB 139Financial Instruments: Recognition and Measurement) (IAS 39). These requirements improve and simplify the approach for classification and measurement of financial assets compared with the requirements of AASB 139 (IAS 39). The main changes from AASB 139 (IAS 39) are described below. (a)     Financial assets are classified based on (1) the objective of the entity’s business model for managing the financial assets; (2) the characteristics of the contractual cash flows. This replaces the numerous categories of financial assets in AASB 139 (IAS 39), each of which had its own classification criteria. (b)     AASB 9 allows an irrevocable election on initial recognition to present gains and losses on investments in equity instruments that are not held for trading in other comprehensive income. Dividends in respect of these investments that are a return on investment can be recognised in profit or loss and there is no impairment or recycling on disposal of the instrument. (c)     Financial assets can be designated and measured at fair value through profit or loss at initial recognition if doing so eliminates or significantly reduces a measurement or recognition inconsistency that would arise from measuring assets or liabilities, or recognising the gains and losses on them, on different bases.	1 January 2013	1 July 2013

4.FINANCIAL RISK MANAGEMENT OBJECTIVES AND POLICIES

The Group’s principal financial instruments comprise cash and short-term deposits, receivables, payables, and financial liabilities.

The Group manages its exposure to key financial risks, including interest rate and currency risk in accordance with the Group’s financial risk management policy. The objective of the policy is to support the delivery of the Group’s financial targets whilst protecting future financial security.

The Group from time-to-time enters into derivative transactions, principally forward currency contracts. The purpose is to manage the currency risks arising from the Group’s operations and its sources of revenue. The main risks arising from the Group’s financial instruments are interest rate risk, foreign currency risk, credit risk and liquidity risk. The Group uses different methods to measure and manage different types of risks to which it is exposed. These include monitoring levels of exposure to interest rate and foreign exchange risk and assessments of market forecasts for interest and foreign exchange rates. Ageing analyses and monitoring of specific credit allowances are undertaken to manage credit risk, liquidity risk is monitored through the development of future rolling cash flow forecasts.

The Board reviews and agrees policies for managing each of these risks as summarised below.

Primary responsibility for identification and control of financial risks rests with the Audit Committee under the authority of the Board. The Board reviews and agrees policies for managing each of the risks identified below, including the setting of limits for hedging cover of foreign currency and interest rate risk, credit allowances, and future cash flow forecast projections.

4. FINANCIAL RISK MANAGEMENT OBJECTIVES AND POLICIES (CONTINUED)

Risk Exposures and Responses

Interest rate risk

The Group’s exposure to market interest rates relates primarily to the Group’s cash, cash equivalents on deposit and term deposits with Australian banks.

The primary goal of the Group is to maximize returns on surplus cash, using deposits with maturities of less than 90 days. Management continually monitors the returns on funds invested. The Group also has a term deposit of greater than 90 days and less than 365 days that has been pledged as security to the Group’s bankers for a trade finance facility.

At balance date, the Group had the following mix of financial assets and financial liabilities exposed to Australian variable interest rate risk that are not designated in cash flow hedges:

	CONSOLIDATED
	2011		2010		2009
	$’000		$’000		$’000
Financial assets
Cash and cash equivalents		3,440		3,608		6,623
		3,440		3,608		6,623
Financial liabilities
Interest bearing liabilities		648		2,056		—
Contingent consideration		2,688		—		—
		3,336		2,056		—

The following sensitivity analysis is based on the interest rate risk exposures in existence at the balance sheet date:

At 30 June 2011, if interest rates had moved, as illustrated in the table below, with all other variables held constant, post tax profit and other comprehensive income would have been affected as follows:

	Post tax profit Higher/(Lower)									Other comprehensive income Higher/(Lower)
	2011			2010			2009			2011		2010		2009
	$’000			$’000			$’000			$’000		$’000		$’000
Consolidated
+1% (100 basis points)		8			36			66			—		—		—
-.5% (50 basis points)		(4	)		(18	)		(33	)		—		—		—

The movements in profit are due to higher/lower interest revenue from variable rate cash balances. The sensitivity is the same in 2011 as in 2010 because the only balances affected by interest rates are cash and interest-bearing loan balances.

Foreign currency risk

As a result of the investment in Synerject LLC, an associate, the Group’s income statement and statement of financial position can be affected significantly by movements in the US$/A$ exchange rates.

The Group also has transactional currency exposures. Such exposure arises from sales or purchases by an operating entity in currencies other than the functional currency.

Approximately 20% (FY2010: 17%) of the Group’s sales are denominated in currencies other than the functional currency of the operating entity making the sale, whilst approximately 14% (FY2010: 26%) of costs are denominated in currencies other than the functional currency of the operating entity making the expenditure.

With respect to assets and liabilities denominated in foreign currencies, the Group ensures that its net exposure is kept to an acceptable level by buying or selling forward foreign currency contracts at spot rates when incurred. The Group does not hold foreign currency positions for trading purposes.

The following sensitivity is based on the foreign currency risk exposures in existence at the balance sheet date:

At 30 June 2011, had the Australian Dollar moved, as illustrated in the table below, with all other variables held constant, post tax profit and other comprehensive income would have been affected as follows:

	Post tax  profit Higher/(Lower)									Other comprehensive  income Higher/(Lower)
	2011 $’000			2010 $’000			2009 $’000			2011 $’000		2010 $’000		2009 $’000
Consolidated
AUD/USD/EURO +10%		4			(46	)		(33	)		—		—		—
AUD/USD/EURO -5%		(2	)		26			19			—		—		—

The movements in profit in 2011 are less sensitive than in 2010 due to the higher level of net US Dollar assets and the net Euro financial liabilities at balance date.

Credit risk

Credit risk arises from the financial assets of the Group, which comprise cash and cash equivalents and trade and other receivables. The Group’s exposure to credit risk arises from potential default of the counter party, with a maximum exposure equal to the carrying amount of these financial assets (as outlined in each applicable note).

The Group does not hold any credit derivatives to offset its credit exposure, however the Group does hold receivable insurance where appropriate.

It is the Group’s policy that all customers who wish to trade on credit terms are subject to credit verification procedures including an assessment of their independent credit rating, financial position, past experience and industry reputation. Risk limits are set for each individual customer in accordance with parameters set by management. These risk limits are regularly monitored.

In addition, receivable balances are monitored on an ongoing basis.

There are no significant concentrations of credit risk within the Group and financial instruments are only invested with a major financial institution to minimise the risk of default of counterparties. An ageing of receivables is included in note 14.

F-26

NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2011

4. FINANCIAL RISK MANAGEMENTS OBJECTIVES AND POLICIES (CONTINUED)

Liquidity risk

The Group’s established a trade finance facility with its bankers during the reporting period. The Group does not have any other bank overdrafts, bank loans, preference shares, finance leases or committed available credit lines at 30 June 2011.

The only external borrowing of the Group are the trade finance facility repayable on terms not exceeding 180 days and the interest free Western Australian Government loan of $14,346,164 repayable in yearly instalments from May 2010 to May 2025.

The Group has recognised an undiscounted contingent consideration liability of $3,474,000 payable in November 2013 to the owners of the non-controlling interest in Sprint Gas (Aust) Pty Ltd.

The table below reflects all contractually fixed pay-offs, repayments and interest resulting from recognised financial liabilities as of 30 June 2011. For all obligations the respective undiscounted cash flows for the respective upcoming fiscal years are presented. Cash flows for financial liabilities without fixed amount or timing are based on the conditions existing at 30 June 2011. The Group’s approach to managing liquidity is to ensure, as far as is possible, that it will always have sufficient liquidity to meet its liabilities when due and payable without incurring unacceptable losses or risks.

The remaining contractual maturities of the Group’s financial liabilities are:

	CONSOLIDATED
	2011 $’000		2010 $’000		2009 $’000
6 months or less		5,652		4,732		5,411
6-12 months		288		240		—
1-5 years		5,329		1,546		19,000
Over 5 years		11,763		12,360		—
		23,032		18,878		24,411

Fair value

The methods for estimating fair value are outlined in the relevant notes to the financial statements.

The Group’s contingent consideration liability belongs to level 3 fair value hierarchy, where the inputs for the valuation of the liability are not based on observable market data (unobservable inputs), (Level 3).

The following table shows a reconciliation of the movement in the fair value of the financial instruments categorised within Level 3 between the beginning and the end of the reporting period.

	three	three	three
At 1 July	—	—	—
Recognised during the year	2,688	—	—
Released to the income statement	—	—	—
At 30 June	2,688	—	—

No gains or losses were recognised in the income statement during the current year due to a change in the fair value of the contingent consideration.

The fair value of the contingent consideration payable was calculated with reference to the estimated future value of the Sprint Gas business, which is based on an estimated average EBITDA multiple. The undiscounted value was discounted at the present value using a market discount rate of 9.8%. If the business was to perform 20% better or 20% worse than forecast the estimated fair value of the contingent consideration would increase by $531,000/decrease by $531,000, respectively

5.SIGNIFICANT ACCOUNTING JUDGEMENTS, ESTIMATES AND ASSUMPTIONS

The preparation of the financial statements requires management to make judgements, estimates and assumptions that affect the reported amounts in the financial statements. Management continually evaluates its judgements and estimates in relation to assets, liabilities, contingent liabilities, revenue and expenses. Management bases its judgements and estimates on historical experience and on other various factors it believes to be reasonable under the circumstances, the result of which form the basis of the carrying values of the assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions and conditions.

F-27

NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2011

5. SIGNIFICANT ACCOUNTING JUDGEMENTS, ESTIMATES AND ASSUMPTIONS (continued)

Management has identified the following critical accounting policies for which significant judgements, estimates and assumptions are made. Actual results may differ from these estimates under different assumptions and conditions and may materially affect financial results or the financial position reported in future periods.

Further details of the nature of these assumptions and conditions may be found in the relevant notes to the financial statements.

(a) Significant accounting judgements

Impairment of non-financial assets other than goodwill

The Group assesses impairment of all assets at each reporting date by evaluating conditions specific to the Group and to the particular asset that may lead to impairment. These include product and manufacturing performance, technology, economic and political environments and future product expectations. If an impairment trigger exists the recoverable amount of the asset is determined. Given the current uncertain economic environment management considered that the indicators of impairment were significant enough and as such these assets have been tested for impairment in this financial period. Value in use models, based on approved budgets and forecasts, have been used to assess impairments of each cash generating unit.

Capitalised development costs

Development costs are only capitalised when it can be demonstrated that the technical feasibility of completing the intangible asset is valid so that the asset will be available for use or sale. During the reporting period the Group identified an impairment trigger in relation to the capitalised development costs for the aftermarket Liquid Phase Injection (LPI) kits and recognised an allowance for impairment of $1,065,000.

Consolidation of Sprint Gas (Aust) Pty Ltd

On 27 May 2011, Orbital Autogas Systems Pty Ltd acquired 55% of the voting shares of Sprint Gas (Aust) Pty Ltd, a new company incorporated to acquire the operating business of Sprint Gas, an Australian business specializing in the importation and wholesaling of Liquified Petroleum Gas (LPG) Fuel systems. Concurrently with the entering into of the Business Acquisition Agreement, the Group entered into a Subscription and Shareholders Agreement with the owners of the 45% non-controlling interest in Sprint Gas (Aust) Pty Ltd. As part of the Subscription and Shareholders Agreement Call and Put options were issued over the remaining 45% non-controlling interest. Management has determined that the Call and Put options, exercisable after 30 months, are in nature a forward contract and in substance represent contingent consideration. The Group has accounted for the business combination as though it acquired a 100% interest and has recognised a financial liability to the non-controlling shareholders equal to the fair value of the underlying obligations under the Put and Call option (Contingent consideration liability).

(b) Significant accounting estimates and assumptions

Taxation

The Group’s accounting policy for taxation requires management’s judgement as to the types of arrangements considered to be a tax on income in contrast to an operating cost. Judgement is also required in assessing whether deferred tax assets and certain deferred tax liabilities are recognised on the balance sheet. Deferred tax assets, including those arising from unrecouped tax losses, capital losses and temporary differences, are recognised only where it is considered more likely than not that they will be recovered, which is dependent on the generation of sufficient future taxable profits. Assumptions about the generation of future taxable profits and repatriation of retained earnings depend on management’s estimates of future cash flows. These depend on estimates of future production and sales volumes, operating costs, capital expenditure, dividends and other capital management transactions. Judgements are also required about the application of income tax legislation. These judgements and assumptions are subject to risk and uncertainty, hence there is a possibility that changes in circumstances will alter expectations, which may impact the amount of deferred tax assets and deferred tax liabilities recognised on the balance sheet and the amount of other tax losses and temporary differences not yet recognised. In such circumstances, some or all of the carrying amounts of recognised deferred tax assets and liabilities may require adjustment, resulting in a corresponding credit or charge to the income statement.

F-28

5. SIGNIFICANT ACCOUNTING JUDGEMENTS, ESTIMATES AND ASSUMPTIONS (continued)

(b) Significant accounting estimates and assumptions (continued)

Share-based payment transactions

The Group measures the cost of equity-settled transactions with employees by reference to the fair value of the equity instruments at the date at which they are granted. The fair value of shares granted under the Employee Share Plan No.1 is the market value on the date of issue. The fair value of the Executive Long Term Share Plan rights is determined by an external valuer using a monte-carlo simulation model, with the assumptions detailed in note 36. The fair value of the performance rights is determined by an external valuer using a monte-carlo simulation model, with the assumptions detailed in note 36. The accounting estimates and assumptions relating to equity-settled share-based payments would have no impact on the carrying amounts of assets and liabilities within the next annual reporting period but may impact expenses and equity.

Impairment of goodwill and intangibles with indefinite useful lives

The Group determines whether goodwill and intangibles with indefinite useful lives are impaired at least on an annual basis. This requires an estimation of the recoverable amount of the cash-generating units, using a value in use discounted cash flow methodology, to which the goodwill and intangibles with indefinite useful lives are allocated. No impairment loss has been recognised in the current year in respect of goodwill.

Product warranty

In determining the level of provision required for product warranties the Group has made judgements in respect of the expected performance of the product, number of customers who will actually use the product warranty and how often, and the costs of fulfilling the performance of the product warranty. Historical experience and current knowledge of the performance of products has been used in determining this provision. The related carrying amounts are disclosed in note 25.

Estimation of useful lives of assets

The estimation of the useful lives of assets has been based on historical experience as well as manufacturers’ warranties (for plant and equipment). In addition, the condition of the assets is assessed at least once per year and considered against the remaining useful life. Adjustments to useful lives are made when considered necessary.

Revenue from Rendering of Services

Revenue from services rendered is recognised in the income statement in proportion to the stage of completion of the transaction at the reporting date. The stage of completion is assessed by reference to the extent of work performed. No revenue is recognised if there are significant uncertainties regarding recovery of the consideration due.

Recognition of contingent consideration

The Group has measured the value of the contingent consideration liability by reference to the fair values of the underlying obligations under the Put and Call options that give rise to the liability. In determining the fair values of underlying obligations under the Put and Call options the Group has made judgements in respect of the expected earnings before interest, depreciation and amortisation expected to be generated by the business during the calculation period.

6.OPERATING SEGMENTS

Identification of reportable segments

The Group has identified its operating segments based on the internal reports that are reviewed and used by the executive management team (the chief operating decision makers) in assessing performance and in determining the allocation of resources.

The operating segments are identified by management based on the manner in which the product is sold, whether retail or wholesale, and the nature of the services provided, the identity of service line manager and country of origin. Discrete financial information about each of these operating businesses is reported to the executive management team on at least a monthly basis.

The reportable segments are based on the similarity of the products produced and sold and/or the services provided, as these are the sources of the Group’s major risks and have the most effect on the rates of return.

F-29

NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2011

6. OPERATING SEGMENTS (continued)

Types of products and services

Engineering services (consultancy)

The engineering services business provides consultancy services to original equipment manufacturers, engine manufacturers and government departments. The engineering services provided include research, design, development, calibration, improvement, production support, performance testing, emissions testing and certification.

Alternative fuels (sale of goods)

The alternative fuels businesses provide LPG fuel systems to an Australian automobile manufacturer, LPG retrofit installers and also operate spare parts businesses for LPG fuel systems.

Royalties and licences (intellectual property rights)

The royalties and licences business receives revenue from licensees of Orbital technologies. Applications utilising Orbital technologies include outboard engines, autorickshaws and scooters.

Accounting policies

The following items and associated assets and liabilities are not allocated to operating segments as they are not considered part of the core operations of any segment:

• Corporate management and finance and administration overhead expenses.

• Share of profit from equity accounted investment.

• Finance costs - including adjustments on provisions due to discounting.

• Cash and cash equivalents.

• Borrowings.

Segment capital expenditure is the total cost incurred during the period to acquire segment assets that are expected to be used for more than one period.

Inter-segment pricing is determined on an arm’s length basis.

Geographical information

The engineering services and royalties and licences segments are managed on a worldwide basis. The alternative fuels segment is managed on an Australian basis.

In presenting geographical information revenue is based on the geographical location of customers and non-current assets are based on the geographical location of the assets.

Revenue is derived predominantly from the provision of engineering services, the sale of LPG fuel systems and the sale of intellectual property rights to Orbital’s OCP technology. The consolidated entity operates predominantly in the automotive, marine and motorcycle engine markets.

Major customers

The Group has a number of customers to which it provides both products and services. The alternative fuels segment supplies an Australian automobile manufacturer (Ford Australia) with LPG fuel systems that accounted for 12.7% of external revenue (2010: 22.9%). The next most significant customer, which accounted for 12.2% of external revenue, was in the engineering services segment (2010: a different engineering services segment customer accounted for 12.1% of external revenue). No other customer accounts for more than 10% of revenue.

Orbital Corporation Limited and its 100% owned Australian resident subsidiaries formed a tax consolidated group with effect from 1 July 2002. Orbital Corporation Limited is the head entity of the tax consolidated group. Members of the group have entered into a tax sharing agreement that provides for the allocation of income tax liabilities between the entities should the head entity default on its tax payment obligations. No amounts have been recognised in the financial statements in respect of this agreement on the basis that the possibility of default is remote.

11.EARNINGS PER SHARE

Basic earnings per share

The calculation of basic earnings per share at 30 June 2011 was based on the profit/(loss) attributable to ordinary shareholders of $1,763,084 (2010: profit $4,515,451, 2009: loss $2,451,250) and a weighted average number of ordinary shares outstanding during the financial year ended 30 June 2011 of 48,325,837 shares (2010: 48,086,676 shares, 2009: 47,756,379 shares), calculated as follows:

Basic earnings per ADS		58.40		150.24		(82.13	)
Diluted earnings per ADS		58.40		148.64		(82.13	)

Shares granted to employees (including Key Management Personnel) as described in note 36 are considered to be potential ordinary shares and have been included in the determination of the diluted earnings per share to the extent they are dilutive. In the current year, no potential shares which are issuable under the ELTSP have been included in the diluted earnings per share calculation. The 2,849,800 rights granted under the ELTSP and the 1,150,000 performance rights have not been included in the diluted earnings per share calculation as they are contingent on future performance.

On April 19, 2010 the ratio of ordinary shares to ADS’s was changed from 40:1 to 160:1. On October 28, 2010 the ratio of ordinary shares to ADS’s was changed from 160:1 to 16:1 (see below).

(1) Share Consolidation

On October 28, 2010 the shareholders in Annual General Meeting approved the consolidation of ordinary shares on the basis that every ten ordinary shares be consolidated into one ordinary share, and where this consolidation results in a fraction of a share being held by a shareholder, the directors of the Company be authorised to round that fraction up to the nearest whole share. The share consolidation became effective on October 28, 2010.

The effect of the share consolidation has been retroactively applied to the number of shares outstanding and Earnings per share calculations above.

On October 28, 2010 the ratio of ordinary shares to ADS’s was changed from 160:1 to 16:1 to maintain the relativities between the ordinary shares and ADS’s following the share consolidation. The effect of the ratio change has been retroactively applied to the Earnings per ADS calculations above.

Trade receivables are non-interest bearing and are generally on 30-60 day terms. An allowance for impairment loss is recognised when there is objective evidence that an individual trade receivable is impaired. An impairment allowance account of $154,000 (2010: $116,000) has been recognised by the Group at balance date. Movement in this allowance account has been included in the other expenses item.

2010	Consolidated		4,138		2,494		1,009		419		100		116
*  Past due not impaired (‘PDNI’) Considered impaired (‘CI’)

Receivables past due but not considered impaired are $549,000 (2010: $519,000). Payment terms on these amounts have not been re-negotiated. Management has been in contact with each relevant debtor and is satisfied that payment will be received in full.

Other balances within trade and other receivables do not contain impaired assets and are not past due. It is expected that these other balances will be received when due.

(b) Fair value and credit risk

Due to the short term nature of these receivables, their carrying value is assumed to approximate fair value.

The maximum exposure to credit risk is the fair value of receivables. Collateral is not held as security.

(c) Foreign exchange and interest rate risk

Detail regarding foreign exchange and interest rate risk exposure is disclosed in note 4.

Goodwill

The goodwill arose on the acquisition of Boral Alternative Fuel Systems on 26 June 2008 ($363,000) and Sprint Gas (Aust) Pty Ltd on 27 May 2011 ($1,373,000).

After initial recognition, goodwill acquired in a business combination is measured at cost less any accumulated impairment losses. Goodwill is not amortised but is subject to impairment testing on an annual basis or whenever there is an indication of impairment.

Capitalised development expenditure

Expenditure on development activities relating to next generation LPG fuel systems for the Ford EcoLPi Falcon have been capitalised. The EcoLPi range of Falcon vehicles were launched by Ford Australia in July 2011.

(c) Impairment losses recognised

Continuing operations

An impairment loss of $1,065,000 on previously capitalised development expenditure was recognised for continuing operations in the 2011 financial year (2010: $nil). The impaired development expenditure related to the development of LPG fuel systems for aftermarket conversions. The impairment loss was recognised as a result of the contraction of the Australian LPG retrofit market, which led to a significant decrease in the number of vehicles being converted to LPG during the reporting period and to lower than expected penetration of our Liquid LPG product into this contracting market. The assessment of recoverable amount was based on a value in use model using a discount rate of 18.4% and was determined at the cash-generating unit level. The cash-generating unit consists of the capitalised development costs relating to the reportable Alternative Fuels Segment. The impairment loss has been recognised in the income statement in the line item “other expenses”.

(d) Impairment tests for goodwill and intangibles with indefinite useful lives

(i) Description of the cash generating units and other relevant information

Goodwill acquired through business combinations have been allocated to and are tested at the level of their respective cash generating units, each of which is an operating segment within the same reportable segment (refer to note 6), for impairment testing:ing as follows:

• Orbital Autogas Systems cash generating unit

• Sprint Gas cash generating unit

Orbital Autogas Systems cash generating unit

The recoverable amount of the Orbital Autogas Systems cash generating unit has been determined based on a value in use calculation using cash flow projections as at 30 June 2011 based on financial budgets approved by management covering a five-year period.

The pre-tax, risk-adjusted discount rate applied to these cash flow projections is 18.4%.

The calculations of value in use for the Orbital Autogas Systems and Sprint Gas cash generating units are most sensitive to the following assumptions:

• Revenue

• Gross margins

• Discount rates

Revenues –revenues for the Orbital Autogas Systems unit are based on expected volumes of production of the Ford EcoLPI Falcon by its largest customer, Ford Australia, over the budget period and for the Sprint Gas unit are based on values achieved in the years preceding the start of the budget period.

Gross margins —gross margins are based on the average values achieved in the years preceding the start of the budget period.

Discount rates— discount rates reflect management’s estimate of the time value of money and the risks specific to each unit that are not already reflected in the cash flows. In determining appropriate discount rates for each unit, regard has been given to the external borrowing rate of the entity as a whole.

(iv) Sensitivity to changes in assumptions

Orbital Autogas Systems cash generating unit

With regard to the assessment of the value in use of the Orbital Autogas Systems cash generating unit, management believes that no reasonably possible change in any of the above key assumptions would cause the carrying value of the unit to materially exceed its recoverable amount.

Sprint Gas cash generating unit

With regard to the assessment of the value in use of the Sprint Gas cash generating unit, management believes that no reasonably possible change in any of the above key assumptions would cause the carrying value of the unit to materially exceed its recoverable amount.

26. LONG TERM BORROWINGS

Non-Current
Loans and advances - secured (a)	7,777	7,604

(a) The Government of Western Australia had previously provided the Company with a fully utilised loan facility of $19,000,000 under the terms of a “Development Agreement”. During the 2010 year Orbital reached agreement with the WA Government through the Department of Commerce for the Restructure of the Non-Interest Bearing Loan.

Under the agreed restructure the original loan has been terminated and replaced by a new loan of $14,346,164 with the following terms and conditions.

• Term - 2010 to 2025.

• Repayments - Commencing May 2010 at $200,000 per annum.

• Repayments - Increasing annually to a maximum of $2,100,000 per annum in 2023.

• Interest free.

The restructured loan’s net fair value at 27 January 2010 utilising a market interest rate of 6.52% was $7,558,000 which compares to the carrying value of the old loan of $15,253,000 at that date. In accordance with the Accounting Standards, the benefit of the interest free government loan amounting to $7,695,000 has been accounted for as a government grant.

This loan facility is secured by way of a second ranking floating debenture over the whole of the assets and undertakings of the Company.

The non-interest bearing loan from the Government of Western Australia was initially recognised at fair value and subsequently stated at amortised cost with any difference between cost and repayment value being recognised in the income statement over the period of the borrowings on an effective interest basis.

The fair value of the loan 2011: $7,423,513 (2010:$7,184,041) is calculated by discounting the expected future cash flows at the prevailing market interest rate at reporting date 2011: 7.23% (2010: 7.17%)

The terms of the Grant included providing the Commonwealth with preferential access to the facility at a discount to the commercial rate. This discount to commercial rates of $512,000 has been transferred to deferred revenue (see note 24).

The government grant will be recognised as income over the periods and in the proportions in which depreciation on the heavy duty engine test facility is charged.

28. CONTINGENT CONSIDERATION

Non-Current liabilities
Contingent consideration for business acquisition	2,688	—

On 27 May 2011, Orbital Autogas Systems Pty Ltd acquired 55% of the voting shares of Sprint Gas (Aust) Pty Ltd, a new company incorporated to acquire the operating business of Sprint Gas, an Australian business specialising in the importation and wholesaling of LPG Fuel systems.

Concurrently with the entering into of the Business Acquisition Agreement, the Group entered into a Subscription and Shareholders Agreement with the owners of the 45% non-controlling interest in Sprint Gas (Aust) Pty Ltd. As part of the Subscription and Shareholders Agreement Put and Call options were issued over the remaining 45% non-controlling interest. The Put and Call options, exercisable after 30 months, are in nature a forward contract and therefore a present ownership interest is granted. The Group has accounted for the business combination as though it acquired a 100% interest and has recognised a financial liability to the non-controlling shareholders equal to the fair value of the underlying obligations under the Put and Call options (contingent consideration liability).

F-51

NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2011

28. CONTINGENT CONSIDERATION (continued)

The underlying obligations under the Put and Call options that gives rise to the contingent consideration liability were initially recognised at fair value and subsequently at fair value through the profit and loss

The contingent consideration payable will be calculated with reference to the estimated value of the Sprint Gas business, based on an estimated average EBITDA multiple. The undiscounted estimated contingent consideration payable is $3,474,000. If the business was to perform 20% better or 20% worse than the current four year forecast the estimated fair value of the contingent consideration would increase by $531,000/decrease by $531,000 respectively.

36. SHARE-BASED PAYMENT PLANS (continued)

(c) Executive Long Term Share Plan (“ELTSP”)

Executives may also be offered shares in the Company’s Executive Long Term Share Plan under which offered shares will be granted subject to the satisfaction of performance conditions over a 3 year period or subject to Board discretion for other qualifying reasons.

The number of shares that the executive actually receives depends on two performance hurdles, as set out below:

(a) 50% of the shares offered will be issued depending on the performance of the Company relative to a group of selected peers (being the 50 smallest companies by market capitalisation (other than resource companies and property and investment trust companies) within the S&P / ASX 300 Index). The peer group is ranked in terms of Total Shareholder Return (“TSR”). TSR is the percentage increase in a company’s share price plus reinvested dividends over a three year period commencing on 1 September 2009 and ending on 31 August 2012 (“Performance Period”).

The following table sets out the relevant percentages of an executive’s Personal Allotment which will be issued at the conclusion of the Performance Period based on the TSR ranking of the Company relative to the peer group:

Company Performance (TSR Ranking)	% of Personal Allotment issued to each executive
Up to the 50th percentile	0%
At or above the 50th percentile but below the 75th percentile	50% to 99% (on a straight-line basis)
At or above the 75th percentile but below the 90th percentile	100%
At or above the 90th percentile	125%

No shares will be granted unless the Company’s TSR is at or above the 50^th percentile. In 2011, nil (2010: 164,300) rights were issued in accordance with the terms of the plan.

(b) 50% of the shares offered will be issued if the Company achieves earnings in excess of 11 cents per share for the year ending 30 June 2013.

At the Company’s Annual General Meeting in October 2010, shareholders approved the above plan in relation to the ongoing remuneration of Executive Directors and senior executives.

During 2011, a total of 1,730,900 rights under the plan were offered to 6 executives (2010: 1,436,000 rights offered to 7 executives).

(d) Performance Rights Plan

The Company also introduced a Performance Rights Plan as part of its long-term incentive arrangements for senior executives, which was approved by shareholders in October 2009.

Under the Performance Rights Plan, performance rights will only be issued if the terms and conditions detailed below are satisfied.

A performance right is a right to acquire one fully paid ordinary share in the Company. Until they are exercised, performance rights:

(i) do not give the holder a legal or beneficial interest in shares of the Company; and

(ii) do not enable participating executives to receive dividends, rights on winding up, voting rights or other shareholder benefits.

Performance rights issued under the Performance Rights Plan will be exercisable if:

(i) a performance hurdle is met over the periods specified by the Board; or

(ii) the Board allows early exercise on cessation of employment (see “Cessation of employment” below); or

(iii) it is determined by the Board in light of specific circumstances.

The Terms and conditions of the offer of Performance Rights made during the year ended 30 June 2009 are as follows:

(i) Mr T D Stinson will be awarded 1,150,000 performance rights;

F-61

NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2011

36. SHARE-BASED PAYMENT PLANS (continued)

(ii) the grant of performance rights will be in seven tranches, each tranche with a different specified share price target as set out below:

Tranche	Number of performance rights		Share  price target $		Fair Value at grant date $
1		200,000	$	2.50		94,000
2		200,000	$	5.00		70,000

6		125,000	$	30.00		11,250
7		100,000	$	50.00		5,000

(iii) the acquisition price and exercise price of the performance rights will be nil;.

(iv) Mr T D Stinson will only be permitted to exercise a performance right if:

• the Company attains the specified share price target (see table above) within eight years from the date of grant of the performance right; and

• the specified share price target is also achieved at the end of two years from the date the target is first achieved (“Vesting Date”) based on the Company’s average closing share price over a 90 day period up to and including the Vesting Date; and

(v) If the specified share price target is either not achieved within eight years from the date of grant, or if so achieved, not also achieved at the end of the Vesting Date, the performance right will lapse.

No performance rights were granted during the year ended 30 June 2011.

37. DEFINED CONTRIBUTION SUPERANNUATION FUND

The Group contributes to a defined contribution plan for the provision of benefits to Australian employees on retirement, death or disability. Employee and employer contributions are based on various percentages of gross salaries and wages. Apart from the contributions required under superannuation legislation, there is no legally enforceable obligation on the Company or its controlled entities to contribute to the superannuation plan.

38. BUSINESS COMBINATION

Initial acquisition of Sprint Gas Business

On 27 May 2011, Orbital Autogas Systems Pty Ltd acquired 55% of the voting shares of Sprint Gas (Aust) Pty Ltd, a new company incorporated to acquire the operating business of Sprint Gas, an Australian business specialising in the importation and wholesaling of LPG Fuel systems. The consideration transferred was $2,000,000 cash as payment in full for 2,200,000 ordinary shares in the new company, Sprint Gas (Aust) Pty Ltd.

Concurrently with the entering into of the Business Acquisition Agreement, the Group entered into a Subscription and Shareholders Agreement with the owners of the 45% non-controlling interest in Sprint Gas (Aust) Pty Ltd. As part of the Subscription and Shareholders Agreement, Put and Call options were issued over the remaining 45% non-controlling interest. The Put and Call options, exercisable after 30 months, are in nature a forward contract and in substance represent contingent consideration. The Group has accounted for the business combination as though it acquired a 100% interest and has recognised a financial liability to the non-controlling shareholders equal to the fair value of the underlying obligations under the Put and Call options (Contingent consideration liability).

The option that gives rise to the contingent consideration liability is classified as a financial liability at fair value through profit and loss.

The acquisition of Sprint Gas significantly broadens the Group’s wholesaling and distribution activities in the area of alternative fuels and positions the Group as a leader in the Australian LPG market.

F-62

NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2011

38. BUSINESS COMBINATION (continued)

Initial acquisition of Sprint Gas Business (continued)

The relocation provision recognised on acquisition was a present obligation of Sprint Gas (Aust) Pty Ltd prior to the business combination and its execution was not conditional upon it being acquired by Orbital Corporation Limited. The key factor contributing to the $1,373,000 of goodwill is the profits expected to be generated by the business during the contingent consideration calculation period. None of the goodwill recognised is expected to be deductable for income tax purposes.

Included in the business acquired were receivables with a gross contractual and fair value of $1,208,000 resulting from trade sales with customers. Management expects these amounts to be collected in full and converted to cash consistent with customer terms, which call for payment within 30-45 days of the initial sale.

The total provisional cost of the combination was $4,688,000 and comprised the payment of cash and the recognition of a contingent consideration liability. As the acquisition was made close to year end, the Company has left the acquisition accounting open pending further adjustment to the fair values of net assets acquired. The initial accounting for the combination will be finalised within the next financial year.

The provisional fair values of the identifiable assets and liabilities of Sprint Gas (Aust) Pty Ltd as of the date of acquisition were as follows:

	Consolidated Fair value at acquisition date $’000
Cash and cash equivalents		420
Trade and other receivables		1,319
Inventories		1,968
Plant and equipment		468
Deferred tax asset		242
		4,417
Trade and other payables		(835	)
Employee benefits		(197	)
Relocation provision		(70	)
		(1,102	)
Provisional fair value of identifiable net assets		3,315
Goodwill arising on acquisition		1,373
		4,688

The fair values have been determined provisionally and based upon the best information available as initial accounting was not complete at the reporting date.

	Consolidated Fair value  at acquisition date $’000
Acquisition-date fair-value consideration transferred:
Cash paid		2,000
Contingent consideration liability		2,688
Consideration transferred		4,688
Direct costs relating to the acquisition (included in administration expenses)		206
The cash outflow on acquisition is as follows:
Net cash acquired with the subsidiary		420
Cash paid (including $200,000 loan to Sprint Gas (Aust) Pty Ltd)		(2,200	)
Net consolidated cash outflow		(1,780	)

F-63

NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2011

38. BUSINESS COMBINATION (continued)

Initial acquisition of Sprint Gas Business (continued)

The consolidated statement of comprehensive income includes sales revenue and net profit for the year ended 30 June 2011 of $1,112,153 and $204,049, respectively, as a result of the acquisition of Sprint Gas (Aust) Pty Ltd.

It is not possible to quantify the impact that the acquisition of Sprint Gas (Aust) Pty Ltd would have had on the consolidated statement of comprehensive income had it occurred at the beginning of the reporting period as separate books and records were not maintained for this business unit.

39. COMMITMENTS

(a) Operating leases

The Group leases premises and plant & equipment under operating leases. The lease for the engineering premises is for a period of 10 years with options to extend for two further periods of five years each. Leases for warehousing premises typically run for a period of 5 years. The plant & equipment leases typically run for a period of 5 years and the lease payments are fixed. None of the leases include contingent rentals.

	CONSOLIDATED
	2011 $’000		2010 $’000		2009 $’000
Non-cancellable future operating lease rentals not provided for in the financial statements and payable:
- Not later than one year		1,022		184		182
- Later than one year but not later than five years		3,536		3		165
- later than five years		4,273		—		3
		8,831		187		350

During the financial year ended 30 June 2011, $489,612 was recognised as an expense in the income statement in respect of operating leases (2010:$171,081).

(b) Other

In June 2008 the Group received funding of $2,760,000 from the Commonwealth of Australia through the Alternative Fuels Conversion Program administered by the Department of the Environment, Water, Heritage and the Arts towards the construction of a heavy duty engine test facility.

The Group will fund the maintenance and operation of the facility until at least financial year 2014/2015 and provide the Commonwealth with preferential access to the facility, as follows:

Operational commitment to the running of the heavy duty engine testing facility not provided for in the financial statements and payable:
- Not later than one year	391	391	391
- Later than one year but not later than five years	682	1,073	1,464

NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2011

40. CONTINGENCIES

The details and estimated maximum amounts of contingent liabilities that may become payable are set out below. The directors are not aware of any circumstance or information that would lead them to believe that these liabilities will crystallise.

In the event of the Company terminating the employment of the Chief Executive Officer (other than by reason of serious misconduct or material breach of his service agreement), an equivalent of 12 months remuneration is payable to the CEO. In the event of the Company terminating the employment of a KMP (other than by reason of serious misconduct or material breach of their service agreement), an equivalent of 4 weeks pay, plus 2 weeks pay for each completed year of service, plus for each completed year of service beyond 10, an additional 1/2 weeks pay, plus a pro-rata payment for each completed month of service in the final year is payable to the KMP. The maximum entitlement to termination pay is limited to 65 weeks pay. There are no other contingent liabilities for termination benefits under the service agreements with Directors or other persons who take part in the management of any entity within the Group.

41. EVENTS AFTER THE BALANCE SHEET DATE

On 11 August 2011 the Company announced that its American Depositary Shares will begin trading on the NYSE Amex on 25 August 2011.

There has not arisen in the interval between the end of the financial year and the date of this report any item, transaction or event of a material and unusual nature that is likely, in the opinion of the Directors of the Company, to significantly affect the operations of the Group, the results of those operations, or the state of affairs of the Group in subsequent financial years.

REPORT OF INDEPENDENT REGISTERED

PUBLIC ACCOUNTING FIRM

The Board of Directors

Synerject, LLC

Newport News, Virginia

We have audited the accompanying consolidated balance sheets of Synerject, LLC and Subsidiaries (the Company) as of December 31, 2010 and June 30, 2009 and the related consolidated statements of income, members’ equity and comprehensive income, and cash flows for the 18 month period ended December 31, 2010 and the 12 month periods ended June 30, 2009 and 2008. The Company’s management is responsible for these consolidated financial statements. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Synerject, LLC and Subsidiaries as of December 31, 2010 and June 30, 2009 and the results of their operations and their cash flows for the 18 month period ended December 31, 2010 and the 12 month periods ended June 30, 2009 and 2008, in conformity with accounting principles generally accepted in the United States of America.

NOTE 1. NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization and Description of Business

Synerject, LLC (Synerject or the Company), a Delaware limited liability company, was formed on June 25, 1997 to manufacture, distribute, and sell fuel rail assemblies incorporating charge delivery injectors which deliver air and premetered quantities of gasoline directly into the combustion chambers of both two-stroke and four-stroke internal combustion engines.

The Company is the result of a Joint Venture and Limited Liability Company Agreement (the Agreement) between Continental Automotive Systems US, Inc. (CAS) and Orbital Fluid Technologies, Inc. (OFT), whereby each member originally owned 50% of the Company. CAS is a wholly owned subsidiary of Continental AG (CAG), a corporation organized under the laws of the Federal republic of Germany. OFT is a wholly owned subsidiary of Orbital Corporation Limited (OCL), a corporation organized under the laws of West Australia.

Pursuant to the terms of the Agreement, allocation of net income (loss) will be to and among the members in accordance with their ownership percentages. As of April 2003, under an amendment to the Agreement, the CEO and CFO of Synerject were added to the Company’s board of directors. Voting control of the Company’s board of directors was shared equally between CAG, OCL, and Synerject. As of April 2009, the CEO and CFO of Synerject were removed from the board of directors.

The initial term of the Agreement is 20 years and is subject to renewal upon terms and conditions as shall be mutually agreed by CAG and OCL.

In November 1998, the Company began functioning as a systems integrator for motorcycle, scooter and other two-wheel applications utilizing direct injection technology. In addition, in September 1999, the Company began functioning as a systems integrator for nonautomotive equipment utilizing certain Continental port injection technology. In April 2003, the Company began systems integration services and supply of systems components to customers in the marine and recreation market segment, and to a new customer, Bombardier Rotax (Austria), for engines supplied to the snowmobile and personal watercraft markets. In March 2006, the Company acquired from BRP US, Inc. a business associated with supplying fuel systems and components of outboard marine engines. As part of its Asian growth strategy the Company began manufacturing operations in Changchun, China in November 2006 and opened a sales and application engineering office in Chongqing, China in March 2007. In September 2010, the Company established a legal entity called Synerject Taiwan Ltd, Co. in Taipei, Taiwan to directly support the technical and commercial demands of customers in the Taiwan market.

NOTE 1. NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

During March 2009, a second amendment to the Company’s joint venture and limited liability company agreement was executed whereby CAS and OFT’s percentage interests changed to 58% and 42%, respectively.

Principles of Consolidation

The consolidated financial statements include the financial statements of Synerject, LLC and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.

Cash and Cash Equivalents

The Company defines cash as cash on hand and demand deposits at financial institutions. Cash equivalents are defined as highly liquid short term financial instruments with maturities of twelve months or less.

Trade Accounts Receivable

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company determines a general allowance utilizing percentages applied to aged outstanding receivable balances. The Company reviews its allowance for doubtful accounts monthly. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have any off-balance sheet credit exposure related to its customers.

Inventories

Inventories which include raw materials and finished goods are stated at the lower of cost or market. Cost includes material, labor and applicable manufacturing overhead and is determined using standard costs, which approximate average costs.

Property, Plant and Equipment

Property, plant and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation and amortization are provided using the straight-line method over the estimated useful lives of the property as follows:

Leasehold improvements	10 Years
Manufacturing machinery and equipment	10 Years
Testing equipment and motor vehicles	5 Years
Tooling	3 Years
Office and computer equipment, Computer Software	3 Years

NOTE 1. NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Intangible Assets – License Agreements

In June 1997, the Company entered into a license agreement with OFT for licensed technology. In November 1998, this license agreement was expanded, and the Company acquired the right to provide system integration services and products to the motorcycle market. In September 1999, the Company obtained a license agreement for the right to use CAS technology for systems integration for nonautomotive equipment. The license agreements are stated at cost, net of accumulated amortization.

In September 2010, the Company reversed the previously accrued capitalized interest that had been accrued on the third of three installments of license fees to Orbital as outlined in the 1998 license agreement, as the conditions in the agreement that require Synerject’s obligation to pay this installment of fees have not been satisfied to date.

Warranty Liability

The Company provides for estimated warranty costs based on historical warranty return data and accrues for specific items at the time their existence is known and the amounts are determinable.

Derivative Financial Instruments and Hedging Activities

The Company used an interest rate swap agreement to limit exposure to rising interest rates on its variable-rate note payable. Interest rate differentials to be paid or received as a result of the swap agreement are accrued and recognized as an adjustment of interest expense related to the associated debt. The interest rate swap agreement was terminated on March 30, 2009.

Derivatives are recognized on the consolidated balance sheet at their fair value. On the effective date of the derivative contract, the Company designates the derivative as either a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (fair value hedge), or a hedge of a forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or liability (cash flow hedge). The Company enters only into cash flow hedge agreements. The Company formally documents all relations between hedging instruments and hedged items, as well as its risk-management objective and strategy for undertaking various hedge transactions. This process includes linking all derivatives that are designated as cash flow hedges to specific assets and liabilities on the balance sheet. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives that are used in hedging transaction are highly effective in offsetting changes in cash flows of hedge items.

NOTE 1. NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Changes in the fair value of a derivative that are highly effective and are designated and qualify as cash flow hedges are recorded in accumulated other comprehensive income until earnings are affected by the variability in cash flows of the designated hedge item.

Income Taxes

The Company has elected to have the income or loss of Synerject reported by the individual members on their U.S. income tax returns rather than by the Company. Accordingly, no U.S. income taxes related to the Company have been provided for in the accompanying consolidated financial statements.

Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 740 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Organization’s management has evaluated the impact of this guidance to its consolidated financial statements. The Organization is not aware of any material uncertain tax positions, and has not accrued the effect of any uncertain tax provisions as of December 31, 2010 and June 30, 2009. With few exceptions, the Organization is no longer subject to income tax examinations by U.S. federal, state or local authorities for years before 2007.

The Company’s policy is to classify income tax related interest and penalties, if any, in interest expense and other expenses, respectively.

No election was made to have the income or loss of one subsidiary, Synerject SAS, reported by the individual members on their income tax return. Synerject SAS incurs and pays foreign income taxes. In addition, the Company incurs a tax (unrecoverable VAT) relating to shipments from its locations in China to other countries. The individual members may be entitled to a tax credit for such foreign income taxes paid if dividends are paid. For the 18 month period ended December 31, 2010, and 12 month periods ended June 30, 2009, and 2008, foreign income taxes of approximately $47,000, $495,000 and $113,000, respectively, were included in other expense on the accompanying consolidated statements of income.

Use of Estimates

Management of the Company has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period to prepare these consolidated financial statements in conformity with U.S. generally accepted accounting principles. Actual results could differ from those estimates.

Translation of Foreign Currencies

The financial position and results of operations of the Company’s non-U.S. subsidiaries and branches are measured using functional currencies other than the U.S. dollar.

For the 18 month period ended December 31, 2010, assets and liabilities are translated at the exchange rate in effect and set forth by CAG at the consolidated financial statement date. Income statement accounts are translated at the average CAG rate of exchange prevailing during the period.

For the 12 month periods ended June 30, 2009 and 2008, assets and liabilities are translated at the exchange rate in effect at the consolidated financial statement date. Income statement accounts are translated at the average rate of exchange prevailing during the period.

Net exchange gains and losses resulting from the translation of foreign financial statements and the effect of exchange rate changes on intercompany transactions of a long-term investment nature are included in the cumulative foreign currency translation adjustment account in total members’ equity.

Impairment of Long-Lived Assets

In accordance with FASB ASC 360, long-lived assets such as property, plant and equipment and purchased intangibles subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount of which the carrying amount of the asset exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less cost to sell.

The total outstanding balance under this line of credit was $594,139 and $1,636,504 at December 31, 2010 and June 30, 2009, respectively. The line of credit agreement provided for a maximum amount available of $7,000,000 effective September 29, 2010 and was reduced back to $5,000,000 effective December 1, 2010 through the maturity date. The line of credit matures June 30, 2011. The line of credit bears interest at the one month London Inter Bank Offered Rate (LIBOR) plus 2.50% with a minimum rate of 3.00% (3.00% rate at December 31, 2010). As of June 30, 2009, the line of credit had an interest rate of the one month LIBOR plus 1.35% (1.67% at June 30, 2009). The line of credit is secured by assets of the Company.

NOTE 6. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

The Company had a derivative instrument to manage its exposure on its variable-rate debt. The Company does not enter into derivative instruments for any purpose other than cash flow hedging purposes. Specifically, the Company does not speculate using derivative instruments.

By using derivative financial instruments to hedge exposures to changes in interest rates, the Company exposes itself to credit risk and market risk. Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. When the fair value of a derivate contract is positive, the counterparty owes the Company, which creates repayment risk for the Company. When the fair value of a derivative contract is negative, the Company owes the counterparty, and therefore, it does not possess repayment risk. The Company minimizes the credit or repayment risk in derivative instrument by entering into transitions with high-quality counterparties. Market risk is the adverse effect on the value of the financial instrument that results from a change in interest rates. The market risk associated with interest rate contracts is managed by establishing and monitoring parameters that limit the types and degree of market risk that may be undertaken.

At June 30, 2008, the Company had one outstanding interest rate swap agreement with a bank having a notional amount of $4,461,290 and terminating on July 1, 2010 (see note 5). The swap agreement provided for the payment of interest based on a fixed rate of 7.43% which remains unchanged over the term of the agreement. The floating rate of the swap agreement is based on LIBOR plus 1.45% (3.91% at June 30, 2008) and is reset monthly based on market conditions. The nature of the swap agreement changes variable-rate debt to fixed rate debt. The interest rate differential paid or received under the swap is recognized over the term of the contract as adjustments are made to the effective yield of the underlying debt. The Company may be exposed to credit loss in the event of nonperformance by the other party to the interest rate swap agreement. The Company does not anticipate such nonperformance. The fair value of the interest rate swap agreement had been determined by the holder of the interest rate swap agreement based on pricing models regarding past, present and future market conditions. The estimated fair value of the interest rate swap at June 30, 2009 was a net liability of $139,312, which is included in accrued expenses – noncurrent.

On March 30, 2009, the above noted swap agreement was terminated in conjunction with the renewal of the related loan. At December 31, 2010 and June 30, 2009, $- and $96,360 of prepaid interest is being amortized over the remainder of the term of the original loan, respectively.

The Company sponsors a defined contribution 401(k) plan for its employees. Participation in the 401(k) plan is voluntary and is open to all employees over 18 years of age with six months of service. Discretionary employee contributions are based upon a percentage of annual salary (as defined by the 401(k) plan). The Company matches 100% of every dollar of employee contributions for the first 1% of the employee’s salary plus an additional 50% contribution of the employee’s contributions above 1% up to a maximum of 6% of the employee’s salary. The Company may also make profit-sharing contributions at its discretion. Company contributions vest over a two-year period. The Company’s total expense under the plan was approximately $381,000, $326,000 and $339,000 for the 18 month period ended December 31, 2010 and 12 month periods ended June 30, 2009 and 2008, respectively.

Intangible assets are amortized using the straight-line method over their estimated useful lives. Aggregate amortization expense for intangible assets for the 18 month period ended December 31, 2010 and 12 month periods ended June 30, 2009 and 2008 were approximately $991,000 $839,000 and $956,000, respectively. Estimated amortization expense for the next five fiscal years is $639,000 in 2011; $624,000 in 2012; $608,000 in 2013; $608,000 in 2014, and $608,000 in 2015.

Under its license agreement with OFT, the Company is contingently obligated to pay additional consideration of $1,000,000 on the last business day of the calendar year in which total sales of OCP Fuel Systems, as defined in the license agreement, reach a certain level. Based on recent sales trends, it is unlikely this hurdle will be met.
