Some Timely Guidance in Relation to Disclosure of Inside Price-Sensitive Information by Main Market and AIM Companies

Looking back over the last 12 months, we have noted an increase in the number of disciplinary measures enforced by regulators against companies admitted to trading on London markets for breach of their respective ongoing disclosure obligations. During this period, three companies listed on the Main Market of the London Stock Exchange have been fined and sanctioned for breach of their respective disclosure obligations to the market. Prior to this, a Main Market company had not been publicly sanctioned since 2005 for such a breach. In 2008, AIM companies received the highest number of sanctions for breach of disclosure obligations compared to any previous year. Appendix 1 contains further details of such enforcement actions over the previous 12 months.
