Dear ASX shareholder,

On 19 August 2010, ASX Limited (ASX) announced its full-year results for the year ended 30 June 2010 (FY10). The ASX Group of companies achieved resilient financial, operational and compliance performance in FY10, in a market environment that remained challenging despite improved conditions following the global financial crisis of the prior year.

• Underlying net profit after tax (excluding significant items) of $332.6 million, up 6.1% on FY09. Statutory net profit after tax (including significant items) of $328.1 million, up 4.6%.

• Operating revenue (excluding interest and dividends) of $588.2 million, up 9.2%.

• Cash operating expenses of $134.2 million, down 3.0%.

• Final dividend of 84.0 cents per share (cps), fully franked, up 12.8%, bringing total fully franked dividends declared in FY10 to 173.1 cps, up 5.0%. ASX has maintained its payout ratio for dividends of 90% of underlying net profit after tax.

Please find enclosed your dividend advice.

The ASX Board has determined that the Dividend Reinvestment Plan (DRP) will apply for the final dividend for FY10. A discount of 1.5% was applied in calculating the allocation price of shares under the DRP, with the final DRP Allocation Price being $29.36.

Information on the DRP can be found at http://www.asx.com.au/about/shareholder/dividend_information.htm

FY10 Overview

As ever, underpinning ASX's financial performance was the soundness of its operational systems and processes. In FY10 this included near 100% availability levels of ASX’s trade execution, clearing and settlement infrastructure, and the smooth functioning of ASX’s market operations, risk management, and surveillance and compliance activities.

ASX’s improved result in FY10 was achieved in parallel with the heavy organisational demands associated with the transfer of supervision of real-time trading and participant conduct on licensed financial markets to the Australian Securities and Investments Commission, completed on 1 August 2010.

Listings activity was dominated by robust secondary capital issuance of $65.1 billion (down on the record $88.1 billion in FY09) and initial public offerings rebounded with 93 new listings (compared to 45 in FY09) as business confidence levels improved. Trade execution activity levels in both the equity and derivative markets recovered strongly in FY10 (up 24.0% and 17.7% respectively), particularly in the June quarter.

As was the case with ASX’s demutualisation and adoption of electronic trading in previous decades, ASX is preparing diligently for the challenges of a newly competitive environment.

• The headline equity market trade execution fee has been almost halved to lower the direct cost of trading for ASX participants.

• New trade execution services and functionality for the equity market have been introduced that also minimise the market impact costs of trading on ASX markets.

• Upgraded trade execution platforms for both the equities and futures markets are anticipated to be implemented in late 2010.

• A new state-of-the-art data centre to allow ASX to expand its co-location hosting services and to upgrade its business continuity requirements for the medium to long-term is scheduled to be operational in late 2011.

On 1 August 2010 ASX Group became the overarching brand name for a new organisation structure. The structure better reflects the range of ASX activities that have the common goal of providing infrastructure necessary for a globally competitive capital market and a vibrant Australian economy.

ASX is well-prepared to meet the upcoming market and regulatory complexity challenges and to grow next year and beyond, given the scalability of its infrastructure, diversity of its business model and focus of its executive management team.

• Complete full-year results and ASX’s FY10 Annual Report are available via the ASX Shareholder Centre: www.asx.com.au/shareholder.

• ASX’s 2010 Annual General Meeting will be held Wednesday, 29 September 2010 at 10.00am (AEST) in the ASX Auditorium, Exchange Square, 18 Bridge Street, Sydney, New South Wales. All shareholders are welcome to attend. Please refer to the Notice of Meeting, sent to you earlier, for further details.

• If you have specific questions you wish to put to the ASX Board or management at the ASX Limited 2010 AGM, they can be emailed to: company.secretariat@asx.com.au.

• ASX’s half-year results for FY11 are expected to be announced on 17 February 2011.

Thank you for your support throughout FY10. I look forward to providing a further update at the AGM.

Yours sincerely,

ASX has been a supporter of ShareGift Australia since it began operations in 2007. ASX reimburses to brokers all exchange fees on ShareGift transactions. To the end of June 2010, ShareGift Australia had donated in excess of $100,000 to Australian charities thanks to the generosity of shareholders.
