Substantial shareholder disclosure requirements
There are disclosure requirements in the UK and Australia applying to holders of substantial shareholdings in Rio Tinto plc and Rio Tinto Limited respectively. These requirements are summarised below.
The particular application of these requirements will depend on matters specific to the shareholding and the shareholder’s circumstances. If a holder is unclear on the application of these requirements, it is recommended they seek legal advice.
UK disclosure requirements
Under the UK Listing Authority’s Disclosure and Transparency Rules (DTRs) any shareholder of Rio Tinto plc holding three per cent or more of the voting rights in Rio Tinto plc as a shareholder is required to give notice to Rio Tinto plc and the Financial Conduct Authority when that shareholding is created, ceases or is increased or decreased by a whole percentage point. The notification to Rio Tinto plc should comply with the requirements of DTR 5.8 and may be submitted to the Company by email to email@example.com.
Australian disclosure requirements
The Australian Securities and Investments Commission (“ASIC”) has made various declarations modifying the application of the Australian Corporations Act as it applies to Rio Tinto’s dual listed companies structure . These modifications include changes to the substantial shareholder disclosure requirements under Chapter 6C of the Corporations Act.
- Rio Tinto Limited
The modified provisions require any person and their associates with voting power of five per cent or more in Rio Tinto Limited to give notice to Rio Tinto Limited and ASX when that holding is created, ceases or is increased or decreased by at least one per cent.
- Rio Tinto plc
Further, the modified disclosure provisions also require a person and their associates to aggregate their holdings of both Rio Tinto plc and Rio Tinto Limited shares to determine if there is a requirement to disclose an interest in Rio Tinto Limited. In broad terms, these provisions require that a person’s interest in voting shares in Rio Tinto plc is taken to give rise to an interest in Rio Tinto Limited calculated as a percentage of the combined voting share capitals of Rio Tinto plc and Rio Tinto Limited.
So for example, where a shareholder and its associates hold:
- 80,000,000 voting shares in Rio Tinto plc; and
- 20,000,000 voting shares in Rio Tinto Limited,
for the purposes of the modified disclosure provisions, the holdings should be aggregated, resulting as shown below in a disclosable interest in Rio Tinto Limited of 5.53%:
These modified rules apply even if a person does not hold any shares in Rio Tinto Limited.
There is no corresponding requirement in the UK to aggregate Rio Tinto plc and Rio Tinto Limited shareholdings for the purpose of disclosure under the DTRs.
