Stock Exchange London Stock Exchange plc is the UK body responsible for marketing company securities. Admission to the Official List, and hence to the main market, is available only to shares of large public companies that have published accounts for the three years preceding the application and that have satisfied the listing requirements of the Listing Transactions Department of the Financial Conduct Authority. These rules ensure that sufficient information is supplied, both on admission and subsequently, to enable investors to assess the merits of the shares. Admission to the Alternative Investment Market (AIM) is available to smaller companies who meet the statutory requirements. Deals in listed shares will usually be arranged through a member of the Stock Exchange acting as a market intermediary and taking a commission. Intermediaries who will themselves buy or sell the securities as principals are called market makers. Face-to-face dealing on the floor of the exchange has now been replaced by the Stock Exchange Electronic Trading System (SETS).
