Exhibit 99.1

1999 Disputed Amended Assessment

with the Australian Taxation Office

High Court denies ATO’s application for special leave to appeal

The High Court of Australia today delivered its decision on the application by the Australian Taxation Office (ATO) for special leave to appeal the Full Federal Court’s decision. The High Court of Australia refused to grant special leave and dismissed the ATO’s application.

On 19 September 2011 James Hardie Industries SE (James Hardie or the company), had been notified that the ATO had made an application for special leave to appeal the Full Federal Court’s decision to the High Court of Australia.

As a result of the decision this matter is now finalised in favour of RCI Pty Ltd (RCI), a wholly-owned subsidiary of James Hardie. The ATO is now obliged to refund A$248 million plus interest, which the company estimates to be approximately A$63 million, plus a portion of RCI’s legal costs. The amount of A$248 million includes A$184.3 million which represents 50% of the original assessment plus general interest charges paid by RCI on the unpaid portion of the original amended assessment.

If the refund is received before 31 March 2012 James Hardie will, subject to the terms and conditions of the Amended and Restated Final Funding Agreement, contribute 35% of the refunded amount to the Asbestos Injuries Compensation Fund in July 2012.

The accounting treatment of the successful outcome of this litigation will be the subject of review during the preparation of the company’s financial statements for the quarter ending 31 March 2012, which are expected to be released on or about 21 May 2012.

The company does not intend to comment further in relation to today’s decision.

Background

RCI received the amended assessment in March 2006. The amended assessment related to the amount of net capital gain arising as a result of an internal corporate restructure carried out in 1998 and was issued pursuant to the discretion granted to the Commissioner of Taxation under Part IVA of the Income Tax Assessment Act 1936.

James Hardie Industries SE, ARBN 097 829 895

Incorporated in Ireland, with registered office at Second Floor, Europa House, Harcourt Centre, Harcourt Street, Dublin 2, Ireland and registered number 485719. The liability of its members is limited.

On 30 May, 2007 the ATO issued a Notice of Decision disallowing RCI’s objection to the amended assessment (Objection Decision). On 11 July, 2007 RCI filed an application appealing the Objection Decision with the Federal Court of Australia. The Federal Court hearing took place in September 2009.

On 1 September, 2010 the Federal Court dismissed RCI’s appeal in respect of the amended assessment. RCI then appealed to the Full Federal Court of Australia. The Full Federal Court hearing took place in May 2011.

On 22 August, 2011 the Full Federal Court upheld RCI’s appeal and ordered that RCI’s objection be allowed in full. The Australian Taxation Office (ATO) had 28 days from the handing down of the judgment to make an application for special leave to appeal the Full Federal Court’s decision to the High Court of Australia.

In fiscal year 2007, in accordance with the ATO Receivables Policy, 50% of the total amended assessment (A$184.3 million) was paid and the company provided a guarantee in favour of the ATO for the remaining unpaid 50% of the amended assessment, pending the outcome of the appeal.

General interest charges (GIC) on the unpaid balance of the amended assessment have also been paid in arrears on a quarterly basis.

Prior to the Federal Court’s decision in September 2010 on RCI’s appeal, the company believed it was more-likely-than-not that the tax position reported in RCI’s tax return for the 1999 financial year would be upheld on appeal. As a result, until 31 August 2010, the company treated the payment of 50% of the amended assessment, GIC and interest accrued on amounts paid to the ATO with respect to the amended assessment as a deposit on its consolidated balance sheet.

As a result of the Federal Court’s decision in September 2010, the company re-assessed its tax position with respect to the amended assessment and concluded that the ‘more-likely-than-not’ recognition threshold as prescribed by US GAAP was no longer met. Accordingly, effective 1 September 2010, the company removed the deposit with the ATO from its consolidated balance sheet and recognised a non-cash expense of US$345.2 million (A$388.0 million) on its consolidated statement of operations for the full year ended 31 March 2011. In addition, the company recognised an uncertain tax position of US$190.4 million (A$184.3 million) on its consolidated balance sheet relating to the unpaid portion of the amended assessment.

The company has regularly reported on the ATO – 1999 Disputed Amended Assessment in its quarterly and annual results lodged with the Australian Securities Exchange and the US Securities and Exchange Commission.
