Exhibit 99.1

August 2010

RCI Pty Ltd v Commissioner of Taxation

James Hardie Industries SE (James Hardie, or the company) advises that it has been informed that judgment in the matter of RCI Pty Ltd v Commissioner of Taxation will be handed down in the Federal Court of Australia at 2.15pm on Wednesday, 1 September 2010.

James Hardie will advise the market of the outcome of proceedings, as soon as possible after the judgment has been made. The company will request a halt in the trade of its securities on the ASX from 2.00pm on 1 September 2010 until a company announcement is made.

Background

In March 2006, RCI Pty Ltd (RCI), a wholly-owned subsidiary of the company, received an amended assessment from the Australian Taxation Office (ATO) in respect of RCI’s income tax return for the year ended 31 March 1999.

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

If RCI’s appeal is ultimately successful, the company expects that amounts paid in respect of the amended assessment will be recovered by RCI (with interest). As a result, the company has treated all payments in relation to the amended assessment made up to 30 June 2010 and related accrued interest receivable as a deposit. At 30 June 2010 this deposit totalled US$234.2 million (A$274.8 million).

Should the judgment of the Federal Court be against RCI, a charge is likely to be required to be recorded while the company continues any appeal process. Had the company been required to take this charge at 30 June 2010 (its last reporting date), the charge would have been an estimated amount of US$330.4 million (A$387.7 million). The company advises it will remain in compliance with its debt covenants should a charge be required to be taken.

However, except for quarterly payments by RCI of interest on the unpaid balance of the amended assessment (being US$157.0 million (A$184.3 million), no cash would be required to be exchanged between RCI and the ATO until the matter has been ultimately resolved.

Both parties have 21 days from the handing down of the judgment to appeal the Federal Court’s decision.
