The London Stock Exchange issued a consultation on proposed changes to the rules governing its popular Alternative Investment Market today.

The proposals include the codification of the role and responsibilities of Nominated Advisers (Nomads) in a new publication, and the introduction of supplemental disclosure requirements for AIM companies.

The new rules for Nomads sets out in more detail the exchange’s expectations of Nomads both when they bring companies to AIM and on an ongoing basis. “This is designed to aid understanding of the exchange’s expectations of Nomads when they are assessing the suitability of issuers for AIM and advising companies about their ongoing compliance with the AIM rules,” it explains. “The Nomad rules reflect current market best practice and provide examples of the types of activities the exchange expects Nomads to undertake in order to confirm to the exchange that a company is appropriate for AIM and ensure it is able to comply with the AIM rules on an ongoing basis.”

The enhanced disclosure requirements for AIM companies, would include the requirement for all AIM issuers to display core management and financial information (including admission documents) on their web site.

“AIM has been a huge success since its launch in 1995. As the market grows and matures and becomes increasingly international in outlook, it is appropriate for the exchange to review the operational and regulatory aspects of AIM to ensure the market’s continued success,” said Martin Graham, Director of Markets and Head of AIM at the London Stock Exchange. “Our proposed changes represent the latest of a number of evolutionary steps that will protect AIM’s core system of regulation while enabling the market to continue to grow and become even more successful.”

The proposed changes are the result of review undertaken by the exchange into the operation and regulation of AIM, and reflect the exchange’s continued commitment to the development of the AIM regulatory model, it said, adding that the proposed changes are intended to preserve AIM’s current system of regulation, whilst at the same time supporting the maturity, growth and increasing internationalization of the market.
