CAB PAYMENTS HOLDINGS PLC – GB00BMCYKB41
Although I don’t claim to be an expert on these Market Identifier Codes (MICs), we’ve come across them before and I’m reasonably confident in saying that they are a bit of a red herring for ISA purposes i.e.. not really relevant.
If you look at HMRC recognised stock exchange’s for ISA qualification purposes, the important point is whether the shares are either listed on a recognised stock exchange or admitted to trading on a recognised stock exchange in the European Economic Area (EEA) or the UK. The MICs are not really relevant for establishing this.
If we look at CAB Payments holding – GB00BMCYKB41, they are listed on the Main Market of the LSE as an equity (see link below), so will qualify for ISA Inclusion.
To qualify for ISA inclusion, a share has to be officially listed on a recognised stock exchange (see ISA Guidance https://www.gov.uk/guidance/stocks-and-shares-investments-for-isa-managers#shareinv) or, from 5 August 2013, admitted to trading on a recognised stock exchange in the European Economic Area (EEA) or the UK.
