In AIM Notice 43, the LSE has confirmed that its AIM Rules for Companies have been updated with effect from 1 January 2016. The changes relate to the admission criteria for investing companies (Rule 8), and the treatment of companies which undertake a fundamental change of business (Rule 15). The proposals were consulted on in October 2015 (see our November newsletter article for more detail), and have been adopted without amendment. Consequential changes to the AIM Note for Investing Companies have also been made with effect from the same date and as set out in the consultation. New versions of the Rules and the Note are available from the LSE's website and include transitional provisions for companies that are already treated as investing companies for the purposes of Rule 15. The new Rules also include minor changes arising from the Central Securities Depositories Regulation as referred to in AIM Notice 41.
