ESMA has issued guidelines on Alternative Performance Measures (APM) for issuers, other than States, whose securities are admitted to trading on a regulated market and who are required to publish regulated information as defined by the Transparency Directive and persons responsible for the prospectus under article 6(1) of the Prospectus Directive. The guidelines are aimed at promoting the usefulness and transparency of APMs included in prospectuses or regulated information. Adherence to the guidelines will improve the comparability, reliability and/or comprehensibility of APMs. Issuers or persons responsible for the prospectus which comply with these guidelines will provide a faithful representation of the financial information disclosed to the market.
