GC100 meaning

What does GC100 mean?
In practice, “GC100” refers to the UK forum of general counsel and company secretaries of FTSE 100 companies. It is a non-statutory, member-led association that provides a peer network for in-house legal and company secretarial leaders, coordinates responses to government and regulator consultations, and contributes to best practice on corporate governance, company law and reporting. The GC100 regularly engages with the FCA, FRC and the Takeover Panel on matters such as the Companies Act 2006, the UK Listing Rules, the UK Corporate Governance Code and the Takeover Code. It publishes non-binding guidance and commentary (for example, with the Investor Group on directors’ remuneration reporting, and materials on directors’ duties and conflicts). Such publications are often cited by practitioners as persuasive but they do not have legal force. The term is not defined in legislation or case law; it is a descriptive expression used across corporate and securities law contexts. Usage is consistent across England & Wales, Scotland and Northern Ireland. In Ireland, the term is understood in reference to UK-listed issuers; while Irish counsel may consult GC100 materials as comparative guidance, it is not part of the Irish regulatory framework.

Share-based remuneration for UK non-executive directors: independence, employees’ share scheme status, Listing/AIM, UK MAR, pre-emption, financial assistance, FSMA, disclosure and practical structuring options

Meaning of ‘non-executive director’ The broad definition of ‘director’ is not closed. Under the Companies Act 2006 (CA 2006), a director is any person who occupies the office of director, whatever title they hold. Accordingly, this covers both executive and non-executive directors (NEDs). Executive directors are typically authorised, either by the company’s constitution or by authority delegated from the board, to manage the company’s day-to-day affairs, and they usually have a full-time service contract. NEDs generally: have no executive powers play a pivotal role in the company’s corporate governance are not employees of the company There are a number of challenges around granting shares to NEDs. This Practice Note considers the issues to assess when offering shares or share-based remuneration to NEDs, including: the potential impact on the NED’s independence the share dealing provisions of Assimilated Regulation (EU) 596/2014 for the UK, and the Market Abuse Regulation (Regulation (EU) 596/2014) previously and for the EU ...

CA 2006 ss 171–174: directors' conduct duties, creditor duty, stakeholder factors, case law, guidance and reporting

Directors’ duties—fundamentals For the first time, the key duties of directors formulated by the courts were expressly set out in statutory form in sections 171–177 of the Companies Act 2006 (CA 2006), thereby consolidating existing judge‑made principles. A full account of these statutory obligations—referred to as the general duties—can be found in Practice Note: Directors’ duties—fundamentals. The first four general duties are set out below: a duty to act in line with the company’s constitution and to use conferred powers solely for their proper purposes as intended by that constitution a duty to act, in good faith, in the manner the director believes is most likely to promote the company’s success for the benefit of all members collectively, while, in doing so, having regard to various factors a duty to exercise independent judgment a duty to exercise reasonable care, skill and diligence With respect to the fifth, sixth and seventh general duties, consult Practice Note: Directors’ duties—directors’ interests: CA...

Precedent Group-wide Dealing Policy (Post-Model Code): FCA/MAR-aligned guidance for UK listed and AIM companies on insider dealing, PDMR restrictions and confidentiality

This precedent memorandum This precedent memorandum presents a specimen group-wide dealing policy issued by The Chartered Governance Institute (formerly known as ICSA: The Governance Institute) (CGI), GC100, the Quoted Companies Alliance (QCA) and other market participants too. It was created after the Financial Conduct Authority (FCA) chose to remove the Model Code, which had formed part of the listing rules, because it conflicted with the EU Market Abuse Regulation that came into force on 3 July 2016. The CGI, GC 100 and the QCA agreed that it would be greatly beneficial for listed and quoted companies to be able to refer to an equivalent version of the Model Code. Companies with a former premium listing of equity shares had previously been required to comply with the Model Code, which restricted persons discharging managerial responsibilities (PDMRs) from dealing in the company’s securities at certain times. The intention is that listed and AIM companies should apply the group-wide dealing policy to PDMRs, their employees and their subsidiaries, to provide an introduction...

This precedent arises from an industry‑led creation of codes, guidance and best practice produced by The Chartered Governance Institute (formerly known as ICSA: The Governance Institute), GC100, the Quoted Companies Alliance and other market participants.

Former UK Listing Rules ‘Model Code’ on PDMR share dealing—restrictions, clearance and exceptions; deleted on implementation of the Market Abuse Regulation

Please be aware that this precedent is provided solely for information purposes and constitutes a memorandum outlining the full particulars of the Model Code formerly included in the Listing Rules, which applied to directors of companies holding a premium listing of equity shares on the Financial Conduct Authority’s Official List. The FCA removed the Model Code as a direct consequence of the implementation of Regulation (EU) No 596/2014 on market abuse (the Market Abuse Regulation), which took effect on 3 July 2016. For further information on the Market Abuse Regulation, see Practice Notes: Market Abuse Regulation (MAR)—essentials [Archived] and UK Market Abuse Regulation—level 2 and level 3 measures.
