Frequently Asked Questions

What is an LEI?

LEI (Legal Entity Identifier) is a unique standardised code for legal entities as part of an international identification system. It combines key reference information that enables clear and uniform identification of legal entities and funds which take part in global financial transactions.

LEI is composed of 20 alphanumeric signs assigned in accordance with ISO standard 17442/2012.

The first four numbers of LEI ensure uniqueness among codes from Local Operating Units (LOU) that issue LEIs. The identification prefix was assigned by the Regulatory Oversight Committee (ROC).

These are followed by two provisional numeric characters (00), while characters 7-18 feature eleven randomly generated numerical characters, which refer to the respective legal entity. The last two characters are check digits in accordance with standard ISO/IEC 7064.

Which entities are required to have an LEI?

In accordance with standard ISO17442 every legal entity/fund acting as a stakeholder in financial transactions needs an LEI, although obligations are determined by the national legal system or regulator, respectively.

The list of regulations identifying entities who are liable to report or assume an LEI, is available on the website of the institution managing the LEI system Global LEI Foundation or GLEIF; Global LEI Foundation or GLEIF.

What information does the LEI contain?

The information available with the LEI reference data consists of two levels, level 1 and level 2. The "level 1" data provides an answer to the question "who is who". In the next step, LEI data is upgraded with level 2' data that answer the question 'who owns whom', enabling the identification of the direct parent and ultimate parent of a specific legal entity.

What information is needed to register for an LEI?

As mentioned above, in order to assign an LEI to legal entity, one has to provide Level 1 and Level 2 data. Please see the required information below:

Provide Opt-Out Reasons for reporting when necessary

  • Legal Obstacles: Obstacles in the laws or regulations of a jurisdiction prevent providing or publishing this information.
  • Consent Not Obtained: The consent of the parent was necessary under the applicable legal framework and the parent did not consent or could not be contacted.
  • Binding Legal Commitments: Binding legal commitments (other than the laws or regulations of a jurisdiction), such as articles governing the legal entity or a contract, prevent providing or publishing this information.
  • Detriment Not Excluded: The child entity has sought to consult the parent entity about the reporting of the parent information but could not confirm the absence of detriment in a way that can appropriately prevent liability risks for the child entity.
  • Disclosure Detrimental: The disclosure of this information would be detrimental to the legal entity or the relevant parent. This will include reasons generally accepted by public authorities in similar circumstances, based on a declaration by the entity.
What is a direct parent company and what is the ultimate parent company?

The LEI ROC follows the following definitions:

  • Direct parent (controlling) company of legal entity X is defined as a legal entity obligated to prepare consolidated statements involving company X at the lowest level. + Share exceeds 50%
  • The ultimate(umbrella) parent company of a legal entity X is defined as a legal entity obligated to prepare consolidated financial statements involving company X at the highest level. + Share exceeds 50%
Do I have to report about the subsidiary companies?
