For these purposes, the value of the securities will be determined in accordance with the prices and corresponding discount factors that the Bank of Mexico makes known to the Institutions, through the internet portal located at the address: <http://webdgobc>.

For the scenario provided in the previous paragraph, the estimated premium will be calculated as follows: On the day of the perfection of the repo agreement, the estimated premium will be that resulting from applying the formula indicated above, for which the interest rate that the Governing Board of the Bank of Mexico has determined as the target rate for monetary policy purposes, expressed annually and in percentage with rounding to two decimal places, which is made known on the internet electronic page of the Bank of Mexico, from the date of perfection until the valuation date, assuming, for the purposes of this calculation, that said rate will remain constant during the remaining term of the repo agreement. Additionally, in the event that, from the day of the perfection of the repo agreement until the agreed date of expiration of the repo agreement term, the aforementioned interest rate that the Governing Board of the Bank of Mexico has determined as the target rate for monetary policy purposes, is modified by decision of the Governing Board of the Bank of Mexico, the value of said rate will be taken as applicable for each of the days from the date it was made known until the agreed date of expiration of the repo agreement term. Without prejudice to the foregoing, the Premium that the Reported Institution must pay to the Bank of Mexico will be that resulting from the calculation performed, at the expiration of the repo agreement, in accordance with what is indicated in the item “Premium” of this paragraph.

The value of the securities subject to the repo agreement will be determined daily, until such time as the repo agreement is liquidated, in accordance with the valuation performed by the Bank of Mexico, and as a result of such determination, the following will be done: a) If the value of the securities, when applying the corresponding discount factor, results in less than the sum of the price of the repo agreement, the estimated premium, and any other agreed expenses, the Bank of Mexico will notify said situation to the Institution in question, which must send a communication within the timeframes and terms established for this purpose in the Manual, indicating how it will cover the amount of the corresponding difference. The Institution must cover, on the same Banking Business Day that the Bank of Mexico notifies that the shortfall is applicable, the amount of the corresponding difference. b) If the value of the securities, when applying the corresponding discount factor, results in greater than the sum of the price of the repo agreement, the estimated premium, and any other agreed expenses, the Institution may request the Bank of Mexico to return the excess guarantees, through a communication sent to the Bank of Mexico in the terms of the Manual.

In the event that the Institution does not cover the amount of the difference, as referred to in subsection a) above, on the next Banking Business Day, the repo agreement will be considered terminated in advance, in which case the Institution must make a payment for the uncovered amount derived from the corresponding difference between the sum of the price of the repo agreement, the estimated premium, and any other agreed expenses, and the value of the securities, when applying the corresponding discount factor. Notwithstanding the foregoing, without prejudice to the corresponding conventional penalty for the uncovered amount, the Institution and the Bank of Mexico may enter into a new repo agreement with the remainder of the securities that the Institution had previously delivered to this entity for a term equal to the remaining term of the original operation.

3. General Provisions. 3.1 Celebration of Contracts.

For the purpose of making payment for the financing operations subject to these Rules, as an exception to what is provided by article 116 of the Operations Provisions, Institutions that celebrate such operations may not incur overdrafts in their respective Single Accounts not covered by guarantees. By virtue of the foregoing, in the event that the respective charge cannot be made at the maturity of the credit operation in question, the payment obligation for the respective credit or repo agreement will be considered breached up to the amount not covered by the Institution in question.

The Bank of Mexico may abstain from celebrating a new operation with an Institution, as well as from renewing previously celebrated operations, when this Institution does not comply with the conditions provided for in these Rules, as stipulated in the respective contract, as well as when said Institution fails to comply with the conditions of other operations celebrated by it with the Bank of Mexico in accordance with the respective Rules issued by it to cover liquidity needs.
