Overview
Implementation agreement
The transaction is governed by an implementation agreement entered into by the parties that includes the following in relation to break fees, exclusivity and liquidated damages arrangements.
Break fee obligations
Subject to certain exceptions, the implementation agreement provides for a break fee of US$195 million to become payable by Rio Tinto to Chinalco in the following circumstances:- The Rio Tinto board withdraws or adversely changes its recommendation that Rio Tinto shareholders approve the resolutions necessary for the transaction.
- The Rio Tinto board recommends a competing proposal.
- Despite a triggering event as defined in the agreement, Rio Tinto shareholders approve the resolutions necessary for the transaction.
- The Rio Tinto board has not withdrawn or adversely changed their recommendation and Rio Tinto shareholders do not approve the resolutions necessary for the transaction, or all or part of the transaction does not complete because a condition precedent is not satisfied.
- An independent expert determines that the transaction is not fair and reasonable.
- The implementation agreement has been terminated or Rio Tinto is unilaterally entitled to terminate the implementation agreement.
The break fee is payable only once and will constitute Chinalco's sole and exclusive remedy in connection with the events and circumstances triggering the obligation to pay.
Exclusivity arrangements
The implementation agreement contains customary terms and conditions for an agreement of this nature which restrict Rio Tinto from soliciting a competing proposal from any third party, or entering into negotiations or discussions in relation to a competing proposal with any third party.
The restriction on negotiations or discussions with third parties does not prevent Rio Tinto from engaging in such negotiations and discussions in the event that the Rio Tinto board (after having considered advice from its legal and, if appropriate, financial advisers), acting in good faith and in order to satisfy what they reasonably consider to be their fiduciary or statutory duties, determine that there is a superior proposal available to Rio Tinto, or one or more proposals may reasonably be expected to lead to a superior proposal. Where the Rio Tinto board has made such a determination, Rio Tinto is required to notify Chinalco of the general nature of that superior proposal. If the Rio Tinto board intends to recommend a superior proposal, then prior to the publication of that recommendation Rio Tinto shall provide Chinalco with the material terms of the proposal and an opportunity to respond.
The above exclusivity arrangements apply from the period commencing on 12 February 2009 and end on the earlier of the date of termination of the implementation agreement, or the date on which the transactions in respect of the convertible bonds, Hamersley Iron, Weipa, Yarwun and (subject to certain conditions) Escondida, complete.
Liquidated damages
Rio Tinto has agreed to a liquidated damages regime in the case of its wilful breach of obligations to establish the joint ventures for Escondida, Grasberg and Kennecott Utah Copper. This is designed to protect Chinalco against the risk that it completes the first tranche of the transaction, and Rio Tinto subsequently breaches the obligations to deliver the balance of the assets. Total liquidated damages payable are US$850 million. The liquidated damages would not be payable unless the shareholders approved the transaction, as the regime only applies once initial completion has occurred.
