CHAPTER XV LOANED PIECES

Article 127. Loaned pieces

The obligation of conservation includes the obligation to refrain from altering or modifying the pieces or any of their characteristics, in any manner.

III. Maintain confidentiality regarding the pieces granted on loan and the information related to them, and therefore must refrain from granting possession or use, revealing, disclosing, publishing, disseminating, or transmitting to any third party, directly or indirectly by any means or for any cause, the pieces granted on loan or the information related to them. The foregoing, with the exception of third parties to whom, with prior authorization from the Bank of Mexico, the Credit Institution allows access to the pieces granted on loan, or to the information relative to said pieces.

TITLE IV ON OTHER PROVISIONS SINGLE CHAPTER RELATED TO BANKNOTES

Article 128. Liberatory power of banknotes denominated in "new pesos"

Banknotes whose denomination is followed by the expression "new pesos" have not been demonetized, and therefore continue to have unlimited liberatory power, in accordance with article 4 of the Monetary Law of the United Mexican States.

Credit Institutions are obligated to receive and exchange banknotes containing the expression "new pesos," removing them from circulation and depositing them in accordance with this Circular, as well as the Cash Instruction.

Article 129. Banknotes to be deposited unsorted

Banknotes that the Bank of Mexico notifies by email to Credit Institutions must be deposited by Users in the country as Banknotes Suitable for Circulation, regardless of their level of deterioration.

Those Credit Institutions not authorized to perform Cash Operations must send the referred Banknotes to be deposited unsorted to Banxico Branches and/or Correspondents through any User; said Banknotes must be delivered to the Bank of Mexico with the User's packaging elements, as mentioned in Chapter III, Title III, of this Circular.

Article 130. Mass deposits of banknotes

Credit Institutions must instruct their Clients who make mass deposits, as well as the E.T.V.s (Third-Party Cash Handling Entities), that work for those Credit Institutions, to refrain from delivering them banknotes for deposit stapled, wrapped with adhesive tape, or by any other means that damages them.

Likewise, Credit Institutions must make known to these Clients and to each E.T.V. that such practices cause premature deterioration of banknotes, which directly impacts the quality of cash in circulation and causes greater requirements for banknote production, which in turn causes higher costs for printing.

Furthermore, based on what is established in article 10 of the Monetary Law of the United Mexican States, in the case that Clients of Credit Institutions who make mass deposits of banknotes do not change their packaging practices, the Bank of Mexico may reject deposits containing banknotes with the characteristics mentioned above.

Monday, March 24, 2025 OFFICIAL GAZETTE

Article 131. Criteria to determine that banknotes retain or lose their value

Credit Institutions must train their own personnel and third-party personnel providing services related to cash handling, such as their cashiers, personnel in charge of attending bank counters, E.T.V. personnel at their service, among others, so that they know and strictly and without exception apply the banknote classification criteria contained in Annex 4, invariably performing the Exchange of banknotes that still retain their value, understanding that according to said criteria, only banknotes that are authentic lose their value if they:

• Are altered. • Are marked with religious, political, and commercial messages intended to disseminate messages directed to the public. • Are repaired with non-transparent adhesive tape. • Are missing portions such that they are considered Fractional Banknotes without Value, for not complying with the qualification rules mentioned in Annex 5. • Contain marks made systematically to deteriorate the pieces, at the judgment of the Bank of Mexico.

Consequently, Credit Institutions must accept and Exchange all banknotes that retain their value, even if they are faded, discolored, or defaced, have non-systematic stains of any material, are scratched, bear names of people, numbers, messages, or legends that do not have the purpose of disseminating messages directed to the public, have complete or incomplete stamps of Credit Institutions, institutions, or companies, are repaired with transparent adhesive tape, or are Contaminated Banknotes, as well as Fractional Banknotes that comply with the classification rules mentioned in Annex 5.

a) If the fraction is formed by one or more parts that have detached from the same Banknote, only the largest part shall be evaluated. The rest of the parts shall not be considered in the evaluation.

b) If a piece is formed by fractions of different Banknotes, it shall be considered an Altered Piece.

c) If the piece is formed by joining a fragment of an authentic Banknote and a fragment of a Presumed Counterfeit Piece, it shall be considered a Presumed Counterfeit Piece.

2. Evaluate the fraction presented by the Holder with the FIRST and SECOND rules.

3. If the fraction is found to be "with value," the Credit Institution shall pay the Holder 100% of the value of the Banknote's denomination.

4. If the fraction is found to be "without value," the Credit Institution shall notify the Holder that, in accordance with these rules, the fraction has no value and shall provide them with the receipt from Annex 7 of this Circular.

5. In both cases, the Credit Institution shall retain and send the banknote fragment to the Bank of Mexico, in accordance with what is established in the Provisions on cash operations, correspondent banking, and handling of presumed counterfeit or altered pieces and the Cash Instruction.

6. These pieces shall be reviewed by the Bank of Mexico, which may consider with value those banknote fragments in which it is certain that the missing parts do not represent any risk of loss for the Bank of Mexico.

a. Once the Credit Institutions receive the result of the Bank of Mexico's analysis, they shall present it to the Holder and reimburse them for the amount of the pieces that, in accordance with said analysis, were found to have value.

b. When it comes to Banknote Fragments with Value, the Credit Institutions shall send to the Bank of Mexico the proof of reimbursement to the Holder, which must meet the requirements indicated in Annex 11.

CRITERIA FOR THE "RECEIPT NUMBER" TO BE GENERATED BY EACH CREDIT INSTITUTION (UNIQUE IDENTIFIER)

1. The receipt number generated by each Credit Institution (unique identifier) consists of 18 digits and has three parts:

a. The first two digits correspond to the year in which the receipt is issued.

b. The next five digits correspond to the key assigned by the Bank of Mexico to each of the Credit Institutions in question. To verify the corresponding key, Credit Institutions may contact the Cash Operations Follow-up Office of the Bank of Mexico at the email address osoc@banxico.org.mx.

c. Each Credit Institution shall generate the remaining eleven digits by its own mechanisms and always ensuring that the receipt number is unique and non-repetitive for the same Credit Institution.

2. The following is an example of a valid receipt number, as it should appear printed on Annex 6 of the Provisions on cash operations, correspondent banking, and handling of presumed counterfeit or altered pieces delivered to the Holder, where XX represents the year and 99999, the key of a credit institution: XX9999900000000001

3. When registering the receipt in the SAM, the system will automatically complement the two digits of the year and the five corresponding to the Credit Institution's key, so each Credit Institution will capture only the last eleven digits. To associate retention with a claim or make modifications, the unique identifier must be captured in full, with its 18 digits.
