The rules in SUP 17 of the Handbook set out what transactions are reportable to us.
In essence, transaction reports are required for transactions involving any instrument that is admitted to trading on a regulated market or on a prescribed market and for transactions in OTC derivatives referenced to an instrument admitted to trading on a regulated market or a prescribed market (except for transactions in commodity, interest rate and foreign-exchange OTC/listed derivatives which are not reportable). The details of which instruments are reportable are set out in Section 3.2 of TRUP.
It is the responsibility of firms to establish an appropriate process for identifying what transactions are reportable to us. Firms can use data vendors to obtain a list of reportable instruments and can use these lists to determine what transactions they report to us.
Firms should make sure that they report trading in financial instruments that are admitted to trading on another market if those securities are also admitted to trading on a regulated market or on a prescribed market with the same instrument identifier, e.g. if the securities have the same ISINs on the different markets.
Over reporting is the reporting of instruments that are not deemed reportable under SUP 17. We recognise that separating out transactions in non reportable instruments may be costly. Firms should take reasonable steps to avoid over reporting of non reportable instruments. We allow firms to over report transactions in non-reportable instruments but we will typically reject such transactions on Aii markets and firms should ensure that any transaction reports they send for non-reportable instruments are complete and accurate.
This database contains details of all shares admitted to trading on a regulated market and is updated on a regular basis. This database also lists all Regulated Markets, Systematic Internalisers, Multilateral Trading Facilities and Central Counterparties.
Please note however that this database does not contain details of all financial instruments reportable under SUP 17.1.4. Firms will therefore need to make other arrangements to obtain details of financial instruments admitted to trading on UK prescribed markets (AIM and ISDX) and equity- and debt-related derivatives and debt instruments admitted to trading on a regulated market.
Moreover, this database does not contain information about equity-like instruments (such as ADRs) admitted to trading on regulated markets
The database is a compilation of information from all ESMA members, who are responsible for the content.
