The Exchange of Securities (General) (Amendment) Rules 1985
The Bank of England and the Stock Exchange have established a computer-based system, known as the CGO Service, to facilitate the transfer of gilt-edged securities. Membership of the new system derives from a contract with the Bank. These Rules, which amend the Exchange of Securities (General) Rules 1979, provide that an acceptance of an offer of exchange of securities need not, in the case of a holding of a CGO Service member, be accompanied by the Bond Book or certificate of title, if at the time of acceptance the holding could be transferred by the member through the CGO Service.
