Connecting your data through symbology
As the amount of data that your firm is using increases, so does the complexity. To get trades, analytics, risk management, compliance, and clearing and settlement done, you need to know that you are engaging with the right companies, financial instruments and more.
Symbology simplifies data complexity. It is the application of data-based identifiers that enable recognition of a security or a legal entity. There are a number of different identifiers that are deployed within the financial services industry for a range of different use cases.
How we help
Our symbology services
We support a number of identifiers to enable you to deliver on your firm’s use cases, such as connecting data across the trade life cycle.
PermID
These are system-assigned, permanent identifiers created across a broad range of objects of information, such as people, organisations, instruments and geographies. Issued by LSEG.
RIC
The RIC is a market-level identifier for instruments and pricing sources issued by LSEG.
Legal Entity Identifier (LEI)
The Legal Entity Identifier is an alpha-numeric code that enables the unique identification of legal entities, based on ISO 17442. LSEG acting in a capacity as an LOU (Local Operating Unit) issues LEIs to legal entities using GLEIF requirements and the LEI Regulatory Oversight Committee (LEI ROC) agreed principles.
