The London Stock Exchange has now brought in a number of rules to toughen up AIM. These changes include the publication of a new rulebook for Nominated Advisers and an enhanced disclosure regime for AIM companies.

Martin Graham, director of markets and head of AIM at the London Stock Exchange, notes that, as the market becomes increasingly international, ‘the Exchange will take incremental steps to build on the quality and integrity of the market’.

The AIM Rules for Nominated Advisers is introduced in addition to the existing AIM Rules for Companies and codifies the role and responsibilities of nomads based on existing market best practice. The new rulebook provides 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.

In addition, the Exchange is introducing enhanced disclosure requirements for AIM companies, such as requiring all AIM companies to maintain a website and to display core management and financial information, including admission documents, on it.
