The technical ISIN [TBC] can be used to populate the following fields in the specified scenarios only:
1. Underlying identification field (Table 2, item 14):
- If a single stock equity that is the underlying of a reportable derivative transaction is issued in a region that does not mandate the use of an ISIN, and no ISIN is available.
- If a pre-IPO single stock equity is the underlying of a reportable derivative transaction. This field should be updated with the relevant ISIN as soon as it becomes available, post-IPO.
2. Identifier of the basket’s constituents field (Table 2, item 18)
- If a custom basket of a reportable derivative transaction is composed entirely of constituents that are either not traded on a trading venue or do not have an available ISIN (for the reasons mentioned in 1. above).
For the avoidance of doubt, the technical ISIN should not be used to report the ISIN field (Table 2, item 7) in any scenario. For reference, a product identifier is not required for derivatives executed on a third-country organised trading platform if neither an ISIN nor a UPI is available, as set out in question 4.5.
Please note that we have held initial discussions with the London Stock Exchange (the UK NNA) regarding the use of a technical ISIN within UK reporting in line with the proposed question 4.14. For reference, the suggested characteristics of the technical ISIN are as follows, although these will be determined by the UK NNA and are not subject to this consultation:
Issuer Name: FINANCIAL CONDUCT AUTHORITY (THE)
