Main Market meaning

What does Main Market mean?
In UK capital markets practice, the Main Market is the london stock exchange’s primary venue for trading listed securities. It is a regulated market under FSMA and UK MiFIR, but “Main Market” is an LSE market name rather than a statutory definition. The market includes: securities admitted to the Official List under the UK Listing Rules (including the single equity shares category that replaced the former Premium and Standard segments), the Specialist Fund Segment, the Shanghai–London Stock Connect Segment, and the High Growth Segment (now closed to new admissions). Issuers seeking admission to trading must comply with the LSE’s Admission and Disclosure Standards and, where applicable, FCA requirements for listing and prospectus approval, together with continuing obligations in the UK Listing Rules, the Disclosure Guidance and Transparency Rules and UK MAR. The Main Market is distinct from AIM (an MTF), which has a different regulatory framework. Usage is consistent across England & Wales, Scotland and Northern Ireland. In Ireland, “Main Market” typically refers to Euronext Dublin’s Main Securities Market (also a regulated market); practitioners refer to the LSE Main Market when dealing with London-listed securities.

SPP warns UK defined contribution pension disclosure plan to promote domestic equity investment risks undermining trustee discretion, conflicting with performance focus and imposing disproportionate reporting burdens

Public disclosures to compare pension schemes The government said that opening up disclosures will enable employers and workers to compare pension schemes more easily. But the Society of Pension Professionals warned the policy could also weaken pension funds’ decision-making authority. Chancellor of the Exchequer Jeremy Hunt outlined the disclosure programme in March 2024, alongside a push for UK pension funds to invest at least 5% of assets in unlisted British companies. In a paper dated 1 May 2024, the SPP noted that the main pension providers—covering more than 15 million UK pension savers—already publish their UK investments via Corporate Adviser magazine’s annual Master Trust & GPP report. The SPP pointed out that such disclosures are already available through that report. According to the paper, the results indicate that funds with higher UK equity weightings have typically underperformed those with minimal or no exposure to the UK market...

FTT: SDLT group relief under FA 2003 Sch 7 denied—arrangements had a main purpose of tax avoidance despite commercial rationale (Tower One St George Wharf v HMRC)

The Tower One St George Wharf Ltd v HMRC [2022] UKFTT 154 (TC) A corporate group was progressing a site for residential use as a development project. The concluding phase involved a 50‑storey tower, which they planned to place into a special purpose vehicle (SPV) to ring‑fence exposure to risk and potential liabilities, and to secure greater financial flexibility for the project as a whole. After consulting their tax advisers, the group executed a sequence of transactions on the very same day intended to step up the tax cost of the scheme, so the SPV would be treated as acquiring it at market value, with no tax liabilities arising along the chain overall. In outline, the company that owned the property granted a 999‑year lease to another group entity, B64. The shares in B64 were then purchased by...

Can a pre-31 Dec 2020 passported FCA-approved prospectus be used for EU public offers after 31 Dec 2020?

Passporting provisions in the Prospectus Regulation Under the Prospectus Regulation, an issuer must publish a prospectus and have it approved by a competent authority when offering securities to the public in the EEA or when applying for admission of securities to a regulated market, where no relevant exemption applies. To streamline cross-border share offerings within the EEA, the EU prospectus regime provides passporting arrangements that permit companies to produce a single prospectus usable throughout the EEA, avoiding the preparation of multiple documents for separate jurisdictions. Articles 24 to 26 of the Prospectus Regulation (EU) 2017/1129 set out these passporting provisions, stating that a prospectus approved by the competent authority in one EEA state (the home member state) can be relied upon in another EEA state (the host member state) without requiring the prospectus to be approved again by the competent authority in the host member state. As a result, a UK issuer has been able to undertake a cross-border share offer across the EEA on the basis of...
