Loan syndication for financing of Alcan acquisition successfully completed

Rio Tinto has successfully completed the sub-underwriting phase of the syndication of its US$40 billion term loan and revolving credit facilities (the “Facilities”). This is the largest ever loan facility raised by a UK corporate and the fourth largest worldwide.

The Facilities will be used to finance the acquisition of all the outstanding common shares of Alcan Inc (“Alcan”) for a total consideration of US$101 per common share representing a total equity consideration of approximately US$38.1 billion and an enterprise value of approximately US$44.0 billion.

The syndication received very strong support despite recent volatility in the global credit markets and was more than one third oversubscribed. The Facilities were initially underwritten by The Royal Bank of Scotland, Deutsche Bank, Credit Suisse and Société Générale.

Guy Elliott, Rio Tinto’s chief financial officer, commented: “This extremely positive response underlines the strength of Rio Tinto’s existing asset base, the attractiveness of the Alcan transaction and the solid credit profile of the enlarged Rio Tinto Group. This bodes well for our future refinancing plans in the debt capital markets.”

The acquisition of Alcan will create a new global leader in the aluminium industry with large, long life, low cost assets. The acquisition will be value enhancing to Rio Tinto shareholders, and is expected to be earnings and cash flow per share accretive to Rio Tinto in the first full year.

Facility details:

Facility B	US$10bn	Revolving Credit Facility	3 years

Forward looking statements

This announcement may contain statements which constitute ‘forward-looking statements’ about Rio Tinto and Alcan. Such statements include, but are not limited to, statements with regard to the outcome of the Offer, and may be (but are not necessarily) identified by the use of phrases such as ‘will’, ‘intend’, ‘estimate’, ‘expect’, ‘anticipate’, ‘believe’ and ‘envisage’. By their nature, forward-looking statements involve risk and uncertainty because they relate to events and depend on circumstances that will occur in the future and may be outside the control of Rio Tinto or Alcan. Actual results and developments may differ materially from those expressed or implied in such statements because of a number of factors, including the outcome of the Offer, revenue benefits and cost synergies being lower than expected, integration costs being higher than expected, levels of demand and market prices, the ability to produce and transport products profitably, the impact of foreign currency exchange rates on market prices and operating costs, operational problems, political uncertainty and economic conditions in relevant areas of the world, the actions of competitors, activities by governmental authorities such as changes in taxation or regulation and such other risk factors identified in Rio Tinto’s most recent Annual Report on Form 20-F filed with the SEC or Form 6-Ks furnished to the SEC or Alcan’s most recent periodic and current reports on Form 10-K, Form 10-Q or Form 8-K filed with the SEC (as the case may be). Forward-looking statements should, therefore, be construed in light of such risk factors and undue reliance should not be placed on forward-looking statements.

Other than in accordance with their legal and regulatory obligations (including, in the case of Rio Tinto, under the UK Listing Rules and the Disclosure and Transparency Rules of the Financial Services Authority), neither Rio Tinto nor Alcan is under any obligation and each of Rio Tinto and Alcan expressly disclaim any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.
