SUBJECT: RULES APPLICABLE TO THE UNIQUE PRODUCT IDENTIFIER (UPI) AND THE UNIQUE TRANSACTION IDENTIFIER (UTI) IN OVER-THE-COUNTER DERIVATIVE TRANSACTIONS

The Bank of Mexico, with the objective of continuing to promote the sound development of the financial system, and considering: a) That financial authorities in various jurisdictions, within the framework of policies and recommendations promoted by the countries that make up the group known as the Group of Twenty (G-20), of which Mexico is a member, as well as the international association known in English as the “Financial Stability Board” (FSB), have pointed out the relevance of adopting various identifiers applicable to over-the-counter derivative transactions; b) That in August 2011, the Committee on Payment and Settlement Systems (CPSS) of the Bank for International Settlements (BIS) and the International Organization of Securities Commissions (IOSCO) jointly pointed out the relevance of international coordination to facilitate the aggregation of risks in the over-the-counter derivatives market when transactions are recorded in different infrastructures. In this sense, the FSB has pointed out the convenience of adopting global identifiers corresponding to transactions and products that allow the data of such operations to be aggregated and improve the quality of the corresponding reporting information, and c) That the Unique Product Identifier (UPI) and the Unique Transaction Identifier (UTI) are internationally accepted to identify financial transactions, whose use reduces the risk that the same transaction is recorded more than once, which facilitates adequate identification of exposures and risks.

LEI Code Rules: the Rules applicable to the Legal Entity Identifier Code (LEI Code), issued by the Bank of Mexico through Circular 14/2015, published in the Official Gazette of the Federation on September 15, 2015, as they have been modified by subsequent resolutions. Derivatives Rules: the Rules for the conduct of derivative transactions, issued by the Bank of Mexico through Circular 4/2012, published in the Official Gazette of the Federation on March 2, 2012, as they have been modified by subsequent resolutions.

UTI: the Unique Transaction Identifier (denominated in English as “Unique Transaction Identifier”), which functions as a reference code to uniquely identify Derivative Transactions and avoid duplication when aggregating them, that is, the compilation of information of said Derivative Transactions.

2. Objective Each Entity, when entering into any of the Derivative Transactions, must have the corresponding Identifiers, in accordance with the terms and conditions provided in these Rules. With respect to the UPI, this Identifier must be available at the time of reporting its information to the Bank of Mexico, with the objective of uniquely identifying the type of Derivative Transaction; its characteristics, and the Underlying information. On the other hand, with respect to the UTI, this Identifier must be available in order to improve the identification of the Entities involved in Derivative Transactions; facilitate their aggregation, and avoid duplication in said process.

Entities, in the Derivative Transactions they enter into, as well as in their obligations to report various information to the Bank of Mexico, must observe the terms and conditions established in the Derivatives Rules, in relation to the Identifiers.

3. UTI 3.1 Structure and general conditions The UTI will be issued in accordance with the international standard ISO 23897 and must have a maximum length of 52 characters, as a result of the concatenation of the following elements: (i) the LEI Code of the Generating Entity, which will occupy the first 20 characters of the UTI, and (ii) a consecutive number or value assigned by the Generating Entity, which must be unique, consist of up to 32 characters, and may contain uppercase letters from “A” to “Z”, excluding “Ñ”, digits from 0 to 9, or both types of characters.

In the event that the LEI Code of the Generating Entity used to generate a UTI loses its validity or validity after the generation of the Identifier, it will not be necessary to update the UTI in question.

3.2 Applicability Entities must have a UTI in all Derivative Transactions they carry out. The UTI of each Derivative Transaction cannot be reused, even if the Derivative Transaction to which it refers is no longer in force.

In the case of transactions that involve simultaneously trading a set of Derivative Transactions in which each Derivative Transaction of the set can be identified, Entities must assign a different UTI to each of them. In the event that Entities cannot identify each of the Derivative Transactions of a set in order to assign a UTI to each of them, Entities must assign a single UTI for that set of Derivative Transactions.

3.3 Generation, validity, and storage The Entity must generate the corresponding UTI at the time of the celebration of the Derivative Transaction or, if applicable, at the time of generating the Confirmation. The aforementioned UTI will be valid from the celebration until the expiration or exercise corresponding to said Derivative Transaction.

However, Entities must generate a new UTI when any of the following situations occur: a) Substitution of any of the Counterparties of the respective Derivative Transaction; b) If, as a result of any Derivative Transaction restructuring process, a novation of the original Derivative Transaction takes place, or compression or division (Split) into multiple new Derivative Transactions, in substitution of the original Derivative Transaction, or c) By the substantial modification of the contract governing the Derivative Transaction, such that these modifications imply a change in the value of the resulting Derivative Transaction, resulting in a novation thereof.

Entities must retain the information of all Derivative Transactions and their respective UTI for a minimum period of five years following the expiration or exercise, as applicable, of the respective Derivative Transaction.

3.4 Generating Entity For the generation of a UTI, the LEI Code of the Generating Entity must be valid, in accordance with what is established for this purpose in the LEI Code Rules, on the date of celebration of the Derivative Transaction.

Entities must observe the following criteria in order to determine the Entity responsible for generating the UTI corresponding to the Derivative Transaction: a) In Derivative Transactions cleared in a Clearing House, each Entity may use the transaction identifier generated by said Clearing House or foreign central counterparty, provided that it complies with the structure provided in 3.1 of these Rules. Otherwise, each Entity must generate the UTI; b) In Derivative Transactions where one Counterparty is a Foreign Financial Entity obliged to report its Derivative Transactions in its respective jurisdiction, the parties involved in the celebration of the Derivative Transaction may agree which of the two will be responsible for generating the UTI. In the event that no agreement is reached, the Counterparty with the shorter deadline to report its Derivative Transactions will be chosen. If this distinction cannot be made, the Entity will be responsible for generating the UTI; c) In Derivative Transactions where both parties are Entities, they may agree on the Entity responsible for generating the UTI. In the event that they do not reach an agreement, the Generating Entity will be that Entity whose LEI Code is first in alphanumeric order, taking into consideration the characters that make up said code in reverse order, and d) In any other case, the Entity will be responsible for generating the UTI.

3.5 Delegation of UTI generation The Entity that is responsible for generating the UTI, in accordance with what is established in 3.4 of these Rules, may delegate the generation of the UTI to any of the Generating Entities, provided that such persons have a valid LEI Code in accordance with what is established in the LEI Code Rules, which will be used in the UTI.

The Generating Entities to which the generation of the UTI is delegated in accordance with the above paragraph, must be able to generate said Identifier in accordance with the characteristics specified in these Rules.

3.6 Inclusion in Confirmation and communication

Wednesday, December 14, 2022 OFFICIAL GAZETTE 157 Confirmations must contain the UTI of the corresponding Derivative Transaction. For this purpose, the Generating Entity must include the UTI of the Derivative Transaction in the corresponding Confirmation, or make it known to the Counterparty responsible for generating said Confirmation so that it includes the respective UTI.

Likewise, the Generating Entity must communicate, if applicable, the UTI to the Counterparties that enter into the Derivative Transaction.

The Entity that delegates the generation of the UTI in accordance with what is established in 3.5 of these Rules, will be responsible for ensuring that the delegated legal entity communicates the UTI to the Counterparties.

3.7 Reports to the Bank of Mexico Entities are obliged to include the UTI in relation to each of the Derivative Transactions that must be reported to the Bank of Mexico, in accordance with what is provided for this purpose in the Derivatives Rules.

4. UPI 4.1 General characteristics of the UPI Entities must have a UPI in all Derivative Transactions they carry out, in accordance with what is indicated for such purposes in the Derivatives Rules, which must be issued by a Provider.

Entities may obtain from any Provider the UPI that corresponds to the Derivative Transactions they carry out, at any time prior to the report they must make to the Bank of Mexico in accordance with 4.3 of these Rules.

The UPI must comply with what is established in the international standard ISO 4914 and consist of 12 alphanumeric characters, in order to identify the type, as well as the Underlying information and the respective Derivative Transaction.
