The Global Legal Entity Identifier Foundation (GLEIF) publishes the monthly ‘Global LEI Data Quality Report’. It provides the following information identifying the overall data quality within the Global LEI System:

  • The LEI Total Data Quality Score for the reporting period.
  • Progress achieved with regard to the continuous optimization of the data quality within the Global LEI System based on the LEI Total Data Quality Score.
  • The Total Data Quality Score per country achieved in the reporting period.
  • Results of GLEIF checks of the LEI data records against implemented quality criteria, i.e. the percentage of records that successfully passed the tests.
  • The percentage of LEI data records, which meet the requirements of distinct quality maturity levels. See the maturity level chart on the right hand side of the report, which shows results with regard to the following maturity levels: Level 1 – ‘Required Quality’ (must be 100 percent for all data records); Level 2 – ‘Expected Quality’ (should be 100 percent); Level 3 – ‘Excellent Quality’ (the higher the better).
  • Information on ‘Level 2’ data, duplicates and challenges for the reporting period. (For background information: In May 2017, the process of enhancing the LEI data pool, by including Level 2 data to answer the question of ‘who owns whom’, began. This data allows the identification of the direct and ultimate parents of a legal entity and, vice versa, in order that the entities owned by individual companies can be researched. The ‘duplicates’ section in the report identifies the following issue: In line with applicable policy, one legal entity must only have one LEI. If it is identified that one legal entity has, for example, three LEIs, then two of these will be marked as duplicates. Duplicate LEIs are flagged in the Global LEI Index with the registration status. The centralized challenge facility made available by GLEIF extends the ability to trigger updates of LEI data to all interested parties.)
  • The section ‘Top 5 Failing Checks’ identifies those data quality checks performed by GLEIF which trigger the highest number of LEI records that fail these checks. In the report, the type of data quality check is indicated with a number. Please refer to the document ‘Data Quality Rule Setting’, available with the supporting documents, to learn which specific check corresponds to the number indicated with the report.

The monthly Global LEI Data Quality Reports are available for download (see below).

* GLEIF published version 1.0 of the November 2017 data quality report on 5 December 2017. This was replaced by version 1.1 on 8 December 2017. The LEI Total Data Quality Score for the reporting period remains 99.68 percent with the updated version. The list showing the five checks, that were mostly failed has been updated to show the correct number of failing LEI issuers and number of total failed records. This update was required, because the numbers included double counts.
