Working Groups


Working Groups and Task Forces

Since its foundation in 1992 ANNA’s tasks have been growing constantly. In order to structure the work of all existing Task Forces, ANNA decided to categorize the existing Task Forces into two categories:

Working Groups (WG) and Task Forces (TF)

While WGs are permanent and looking into strategic matters, TFs should present their results to the General Meeting in a limited period.

At present three Working Groups are in operation.

WG1 (Assisting Markets)

Primarily assistance is given to the applicants of ANNA membership and partnership in all ANNA related matters as well as to new members and partners. Members of this WG are representatives of the four Substitute Numbering Agencies (CUSIP Global Services, SIX Financial Information, WM Datenservice and National Settlement Depository Russia).

WG2 (ISIN Quality and Guidelines)

This working group is focused on topics related to the guidance on ISIN allocation. The WG is also in charge of the periodical review of the ISIN allocation rules. All members are invited to contact the WG if they have basic questions/problems with regards to ISIN allocation. The WG has already developed several versions of the ISIN Guidelines that are provided through the ANNA website.


The ANNA LEI Working Group, WG5, establishes procedures the members of ANNA can follow for ensuring the implementation of the LEI in accordance with rules and regulations published by the FSB and the ROC. Furthermore, WG5 advises ANNA members who want to become a LOU or to assist a LOU in their area of jurisdiction. Currently the work of WG5 is on hold.

TF 21 (Benchmarks)

The focus of this newly formed task force is on improving coverage and data quality of ISINs for benchmarks.
