Dear colleague I am a product manager at CoreFiling, a provider of XBRL software and services. I am writing to obtain some clarity on a SII filing rule following conversations with some of our clients. It relates to instrument codes that are attributed by the undertaking ("CAU") and what form they need to take in order to pass the filing rules. The manual (versions 2.4 and 2.3, paragraph IV.3.2) seems to suggest the code should be of the form CAU/INST/{code}. However it does also refer to other CAU code types. In order to correctly validate this, can you confirm which codes are permissible and can be submitted successfully by a filer? If you have any questions please do let me know.

Background of the question

This has come as a result of clients asking us to clarify the above mentioned rule - we advised we would contact EIOPA directly

EIOPA answer

Please note that the expected data structures are listed below and additionally validated via xbrl assertions. It is expected that codes are used as listed below being the CAU/INST only used then standard codes are not available. If you have specific questions on xbrl please contact xbrl@eiopa.europa.eu and for business validations validations@eiopa.europa.eu

For identification of an instrument based on “code” and “type of code” predefined pattern (one of the following) MUST be used:

1. ISIN/{code} for ISO 6166 ISIN code,

2. CUSIP/{code} for The Committee on Uniform Securities Identification Procedures numbers assigned by the CUSIP Service Bureau for U.S. and Canadian companies,

3. SEDOL/{code} for Stock Exchange Daily Official List for the London Stock Exchange,

4. WKN/{code} for Wertpapier Kenn-Number,

5. BT/{code} for Bloomberg Ticker,

6. BBGID/{code} for Bloomberg Global ID,

7. RIC/{code} for Reuters instrument code,

8. FIGI/{code} for Financial Instrument Global Identifier,

9. OCANNA/{code} for other code by members of the Association of National Numbering Agencies,

99. CAU/INST/{code} for code attributed by the undertaking.

Instrument code MUST use the following priority:

- ISO 6166 code of ISIN when available (ISIN),

- Other recognised codes (CUSIP, SEDOL, WKN, BT, BBGID, RIC, FIGI, OCANNA)

- Code attributed by the undertaking (CAU/INST), must be used as the default option when none of the options above are available. This code must be unique and kept consistent over time.  Additionally, when spaces are not having a particular meaning for the codes (i.e. there are not two different codes like “CAU/INST/PT 23” “CAU/INST/PT23”) is recommended to remove the spaces and particularly if they are at the start or at the end of the code (“CAU/INST/ PT23“).
