Insider list meaning

What does Insider list mean?
An insider list is the confidential record kept by an issuer and by anyone acting on its behalf (such as advisers) of every individual who has access to inside information in the course of their work. It is a compliance tool used to control, monitor and evidence the handling of inside information and to deter unlawful disclosure and insider dealing. The obligation to draw up and maintain insider lists is set out in Article 18 of the Market Abuse Regulation: in the UK, the retained UK MAR (Regulation (EU) 596/2014, as onshored) and, in Ireland, EU MAR. Requirements are broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland. Key features include: identifying details of each person, the reason they are on the list, the date and time they obtained and, where relevant, ceased access; prompt updates; keeping the list for at least five years; and making it available to the FCA (UK) or Central Bank of Ireland on request. Issuers must take all reasonable steps to ensure listed persons acknowledge their legal duties. Lists are commonly divided into event‑based (deal/project‑specific) sections and a permanent insiders section.

Private share or asset acquisitions involving UK listed and other public companies: UKLR/AIM significant transactions and reverse takeovers, related party rules, UK MAR/DTR disclosure, and Takeover Code issues

Practice Note This Practice Note sets out the matters that may arise on a private M&A deal (whether implemented as a share acquisition or an asset acquisition) where a counterparty is a company whose shares are listed in the equity shares (commercial companies) category or in the transition listing category on the Financial Conduct Authority’s (FCA) Official List and are admitted to trading on the main market for listed securities (Main Market) or admitted to trading on AIM. It also addresses points common to all public companies, whether exchange-listed or not. In these scenarios, the buyer and/or seller may need to release suitable market announcements containing certain mandated enhanced disclosures. Where the deal amounts to a reverse takeover (see below) and the purchaser is a listed company, the purchaser may have to dispatch an explanatory circular to shareholders and secure their approval for the acquisition at a general meeting (that approval will become a condition to completion and therefore influence the timing of the acquisition). The principal additional procedures...

This Practice Note outlines the disclosure obligations for transactions undertaken by a person discharging managerial responsibility (PDMR) and persons closely associated with them (PCAs) under the UK Market Abuse Regulation (Assimilated Regulation (EU) 596/2014), and also examines guidance from the Financial Conduct Authority (FCA) in Chapter 3 of the Disclosure Guidance and Transparency Rules (DTR) and from the London Stock Exchange in relation to AIM companies.

At the end of the Brexit implementation period (11pm UK time on 31 December 2020), the EU Market Abuse Regulation was onshored into UK law and...
