Corporate Structure

Bloomberg’s Corporate Structure data provides basic reference data and hierarchical relationships (parent, subsidiary, ultimate parent) across nearly 4 million legal entities. Firms are able to leverage the relationships between instruments and issuers to assess concentration risk across region, sector, and issuers. In addition, this dataset contains the Legal Entity Identifier (LEI), which is a market standard identifier used in trade reporting and other regulatory reporting global mandates.

Sanctions Compliance

Bloomberg’s Compliance data provides information about 20 sanctions programs at the legal entity level across 10 jurisdictions worldwide. Used for entity screening as part of the Customer Due Diligence workflow, this dataset helps firms maintain compliance with KYC and AML regulations. In addition, as part of a pre-trade compliance process, this dataset also contains information about 10 sanctions programs at the Instrument level.

Capital Structure

Bloomberg’s Capital Structure product details a company’s capital structure by seniority {CAST<GO>} and by maturity {DDIS<GO>} and is used primarily by either proprietary credit research or risk management applications. Outlined at the company level, this dataset ties seamlessly to our Corporate Structure data and can be linked to our Instrument data. Coverage is approximately 2,700 companies and more than 25,000 unique entities.

Issuer Risk

Bloomberg’s Issuer Risk dataset provides an independent evaluation of a company’s credit health, using market data (share price and volatility), fundamental data, and cutting-edge quantitative models. The product delivers a 12-month and 5-year default risk probability, as well as a 5-year implied CDS spread, even for companies without a market CDS. The product includes historical data back to 1999 and earlier, where applicable.


Bloomberg’s Ontology dataset is a comprehensive data dictionary that accompanies the Reference Data product. It includes metadata that details all fields, including their definitions, datatypes, and properties, as well as content sets, including their components. In addition, Bloomberg provides its Provenance metadata, which is descriptive metadata about the delivery of content, and which allows firms to calculate the lineage of their Bloomberg data.
