b) Interactive: That in which all Bidding Institutions present their respective bids in the respective Auction with knowledge of the marginal assignment price from the moment the total amount of bids presented by the Bidding Institutions is equal to the amount offered in the respective Auction.

Both types of Auctions will be carried out based on a multiple-price assignment, that is, the offered amount of Foreign Exchange Hedges will be assigned starting from the highest bid, in terms of what is stated in Rule 11a of these Rules, understanding that the assignment of the corresponding bids will be carried out based on the Exchange Rate indicated by each Bidding Institution.

CHAPTER II BIDS

7a. Characteristics.- Bidding Institutions must present competitive bids in each Auction, indicating in them the following:

a) The Exchange Rate, expressed in four decimals, that the Bidding Institution is willing to have established as the Assignment Exchange Rate for the Foreign Exchange Hedge celebrated as a result of the respective Auction, and

b) The amount in Dollars for which the Bidding Institution is willing to celebrate the Foreign Exchange Hedge, which must be, at minimum, one million Dollars or multiples of that amount.

8a. Limits of Bids.- For traditional auctions referred to in Rule 6a, item a), of these Rules, the sum of the amounts of bids presented by the same Bidding Institution in the same Auction must not exceed the total amount that the Bank of Mexico indicates in the call for said Auction as corresponding to the total Foreign Exchange Hedges that can be assigned.

9a. Presentation of Bids.- Each Bidding Institution may present one or more bids in an Auction conducted under the same call.

Interested Bidding Institutions must present their bids on the date and time indicated in the respective call, through SUBCAM-BANXICO.

In case bids cannot be presented through SUBCAM-BANXICO, the Bank of Mexico, exceptionally, will authorize their presentation, within the time established for the conduct of the respective Auction, by telephone communication with the staff of the Sub-Manager of National Exchanges or through any other electronic, computing, or telecommunications medium authorized for that effect by the Bank of Mexico, as the Bank of Mexico will make known to the Bidding Institutions in due course. Bidding Institutions that present bids under the supposition of this paragraph must confirm their bids in writing addressed to the National Operations Management of the Bank of Mexico, presented in a closed envelope, no later than 17:00:00 hours on the same Banking Business Day of the respective Auction, in a format substantially equal to the one attached to these Rules as Annex 2, accompanied by a letter of presentation, as applicable for each call of the respective Auction.

The aforementioned writing must be accompanied by the signature knowledge that the respective credit institution has previously registered at the Bank of Mexico.

10a. Effects of Bids.- The presentation of bids by Bidding Institutions in the respective Auctions constitutes evidence of their consent to celebrate the Foreign Exchange Hedges subject to said Auctions, in the terms and under the conditions established in these Rules and in the respective calls. In turn, the assignment of Foreign Exchange Hedges that the Bank of Mexico carries out in each Auction perfects said Foreign Exchange Hedges at the moment when the referred assignment is made known to the corresponding Assigned Institutions, and consequently, the latter are obliged to make the payments that, if any, result from said operations, as well as to comply with the other related obligations, in terms of these Rules.

Any bid presented in an Auction in accordance with these Rules has an obligatory character for the Bidding Institution that presents it and is irrevocable.

The Bank of Mexico may invalidate the bids it receives if they do not comply with these Rules or what is stated in the respective call; are not clearly legible; have amendments or corrections; or are incomplete or incorrect in any way.

Likewise, the Bank of Mexico may declare the Auction void or reject any bid if, in its judgment, the participation of the respective Bidding Institutions in said Auction, due to their characteristics, could produce inconvenient effects on the healthy development of the foreign exchange market or the financial system in general.

The Bank of Mexico may limit the participation of one or more Bidding Institutions when the bids they present do not comply with sound market practices.

CHAPTER III ASSIGNMENT

11a. Assignment Criteria.- The Bank of Mexico will assign the respective bids in the corresponding Auctions, in descending order of the Exchange Rates indicated in the respective bids, without exceeding the total amount offered in the respective call. In case the value of the total bids exceeds said auctioned amount, only those with an accumulated value equal to this will be accepted.

In case two or more Bidding Institutions present their bids with the same Exchange Rate and that, in accordance with the order stated in the previous paragraph, they remain in the last place of assignment to cover the total amount offered by the Bank of Mexico in the respective Auction, such that the total amounts of bids with higher Exchange Rates do not reach to cover said offered amount, but the sum of the amounts of said last bids exceeds this last amount, the assignment of said last bids will be made pro rata according to the amount indicated in said bids, when it is a traditional Auction, or according to the order in which they were received when the corresponding Auction is interactive.

In case failures occur in the systems during the period between the presentation of bids and the moment when the results of the Auctions are made known, the Auction will be declared void, even in the case where the Bank of Mexico has received bids. In this supposition, the Bank of Mexico will call for a new Auction on the same day, by the same medium or, in the absence of provision of this, by any other electronic, computing, or telecommunications medium authorized for that effect by the Bank of Mexico and made known to credit institutions.

CHAPTER IV RESULTS

12a. Report of Auction Results.- The Bank of Mexico will make available to the Bidding Institutions that have participated in an Auction, through SUBCAM-BANXICO or through any other electronic, computing, or telecommunications medium authorized for that effect by the Bank of Mexico and made known to Bidding Institutions, the results of the respective Auction, no later than ten minutes after the deadline for the presentation of bids. Such information will remain available to Bidding Institutions through the mentioned medium, until the general results of a new Auction are incorporated.

In the event that, due to force majeure or fortuitous event, SUBCAM-BANXICO cannot be used to make known the calls or inform the results of the Auctions, the Bank of Mexico will timely communicate the procedure that will be followed for such purposes.

CHAPTER V SETTLEMENT

13a. Calculation of Settlement Amount.- The settlement of each Foreign Exchange Hedge celebrated by an Assigned Institution will be for the amount, in national currency, resulting from multiplying: (i) the amount assigned in the Auction to said Assigned Institution, by (ii) the result of subtracting, from the Settlement Exchange Rate, the Assignment Exchange Rate.

In the event that the Assignment Exchange Rate is lower than the Settlement Exchange Rate, the Assigned Institution will have the right to receive from the Bank of Mexico the settlement amount calculated in accordance with the previous paragraph, and in case the Assignment Exchange Rate is higher than the Settlement Exchange Rate,

of Settlement, the Assigned Institution shall be obligated to pay the Bank of Mexico the respective settlement amount.

14th. Settlement.- On the second Banking Business Day following the maturity of each Foreign Exchange Coverage entered into by each Assigned Institution, the Bank of Mexico, in accordance with the authorization referred to in Rule 5th of these Rules, shall charge or credit, as applicable, in national currency, the settlement amount resulting in accordance with the previous Rule in the Unique Account of said Assigned Institution, subject to what is established in this regard in the Applicable Provisions to the Operations of Credit Institutions and the National Financial Development Bank for Agriculture, Rural, Forestry and Fisheries, issued by the Bank itself through Circular 3/2012, as well as modifications to said provisions issued subsequently.

On the maturity date of each Foreign Exchange Coverage entered into by each Assigned Institution and once the Bank of Mexico has published the Settlement Exchange Rate, it shall issue a call for a new Auction in accordance with what is provided in these Rules, for at least an amount equal to the Foreign Exchange Coverages that, in accordance with what is provided in the preceding paragraph, mature on the day of the Auction referred to in this paragraph.

CHAPTER VI GUARANTEE AND EARLY MATURITY

15th. Determination of the value of Foreign Exchange Coverages.- The Bank of Mexico will calculate, on each Banking Business Day, the value of each of the Foreign Exchange Coverages entered into by the Assigned Institutions, as the equivalent result of multiplying: (i) the amount of the Foreign Exchange Coverage that was assigned in the corresponding Auction, by (ii) the result of subtracting, from the Revaluation Exchange Rate, the corresponding Assignment Exchange Rate. The value of those Foreign Exchange Coverages whose Assignment Exchange Rate is greater than the Revaluation Exchange Rate will be considered as owed by the respective Assigned Institution and, on the other hand, the value of those Foreign Exchange Coverages whose Assignment Exchange Rate is less than the Revaluation Exchange Rate will be considered as due to that same Assigned Institution.

Once the Bank of Mexico carries out the calculation of the value referred to in the preceding paragraph, for each Foreign Exchange Coverage entered into by the same Assigned Institution, it will calculate the aggregated value of all Foreign Exchange Coverages entered into by this one, as the result of the following arithmetic subtraction: (i) the sum of the amounts equivalent to the value of the Foreign Exchange Coverages owed by that Assigned Institution, minus (ii) the sum of the amounts equivalent to the value of those other Foreign Exchange Coverages due to that Assigned Institution.

The Bank of Mexico will inform, on the same day it carries out the calculation referred to in this Rule, to each of the Assigned Institutions that are parties to Foreign Exchange Coverages pending settlement, through the address << http://webdgobc >> or through any other electronic, computing or telecommunications medium authorized for this purpose by the Bank of Mexico and made known to said Assigned Institutions, the Revaluation Exchange Rate used for the calculation of the value of the aforementioned Foreign Exchange Coverages, as well as the aggregated value of the valuations corresponding to all Foreign Exchange Coverages that resulted from the calculation provided for in this Rule.

16th. Guarantees of obligations owed by Assigned Institutions.- Assigned Institutions that enter into Foreign Exchange Coverages in accordance with these Rules shall be obligated to guarantee, until such time as the amounts of payments derived from said operations are settled, the fulfillment of the obligations that may arise against them in terms of what is provided in these Rules.

For the purposes of what is provided in the preceding paragraph, in the event that the aggregated value referred to in the previous Rule results in favor of the Bank of Mexico, it shall make known to the respective Assigned Institutions, on the same day it carries out the calculation provided for in that same Rule, through the address << http://webdgobc >>, the amount of the Guarantees that these must constitute to cover that part of the value of the respective Foreign Exchange Coverages that results as owed by said Assigned Institutions in accordance with the aforementioned Rule.

In order to constitute the Guarantees referred to in this Rule, the valuation of the Securities that will be taken into account for said Guarantees will be determined in accordance with the methodology and procedure described in Annex 3 of these Rules, which shall be applied depending on the type of Security involved, as well as on the corresponding parameters that the Bank of Mexico makes known to the Assigned Institutions through SAGAPL or through any other electronic, computing or telecommunications medium authorized for this purpose by the Bank of Mexico and made known to said institutions.

The Assigned Institution that must constitute the Guarantees in accordance with what is provided by this Rule shall, in the case of: a) Securities: under the terms and conditions provided in the contract celebrated for this purpose in accordance with Rule 5th of these Rules and before the closing time of operations of INDEVAL on the Banking Business Day immediately following that on which the Bank of Mexico made known to it the amount of the respective Guarantees referred to in the preceding paragraph, deposit as security the Securities object of said Guarantee, through the transfer it carries out in the account of the Bank of Mexico that, for such purposes, it has opened in INDEVAL, and b) Deposits: send a request to the Bank of Mexico in a format substantially identical to the one attached to these Rules as Annex 4, no later than 16:00:00 hours on the Banking Business Day on which they intend to constitute the Guarantee, in which they indicate the type of Deposit they intend to affect as Guarantee, as well as the amount of each of them. In this case, the Bank of Mexico will verify the availability of the Deposits to be granted as Guarantee. Regarding Guarantees constituted over Deposits, the Assigned Institution must request that, for such purposes, the respective amounts be segregated into a special account for guarantees for Foreign Exchange Coverages that it enters into with the Bank of Mexico. Regarding deposits in the US dollar account, the value of this Guarantee will be determined by applying the exchange rate published by the Bank of Mexico in the Official Journal of the Federation on the date of constitution of said Guarantee minus the discount factor that the Bank of Mexico makes known to the Assigned Institutions through the internet site located at the address <http://webdgobc>.

The document referred to in this subsection must show knowledge of signature, so that said signatures must be previously registered at the Bank of Mexico.

In the event that the Assigned Institution referred to in the preceding paragraph does not constitute the respective Guarantees within the deadline established in said paragraph, the Bank of Mexico will charge, for each day of delay, the next Banking Business Day, in the Unique Account of said Assigned Institution, as a conventional penalty, the equivalent to one percent of the unguaranteed amount.

17th.

In this case, the Bank of Mexico reserves the right to reject or accept said request.

The document mentioned in the preceding paragraph must show knowledge of signatures, so that said signatures must be previously registered at the Bank of Mexico itself.

18th. Withdrawal of excess guarantees.- In the event that the amount corresponding to the valuation of the Securities object of the Guarantees constituted by an Assigned Institution in accordance with what is provided in Rule 16th of these Rules is superior to the part determined by the Bank of Mexico of the aggregated value of the Foreign Exchange Coverages that said Guarantees must cover, the Assigned Institution may request the Bank of Mexico for the return of Securities or the termination of the Guarantee constituted over the Deposits for the excess amount corresponding, through communication in a format substantially identical to the form included in Annex 6 or Annex 7 of these Rules, as applicable, presented no later than 14:15:00 hours on the Banking Business Day on which it requests to receive said Securities or to consider terminated the Guarantee over Deposits. In the event that the Bank of Mexico receives the aforementioned request after the hour indicated in this paragraph, it will carry out the transfer of the respective Securities to the next Banking Business Day subject to the valuation carried out in accordance with these Rules.

The document mentioned in the preceding paragraph must show knowledge of signatures, so that said signatures must be previously registered at the Bank of Mexico itself.

19th. Crediting of accessories.- In the event that the Bank of Mexico obtains any payment corresponding to any accessory right, such as interest or coupon payment, derived from the Securities deposited in the guarantee account or from the Deposits referred to in Rule 16th of these Rules, the Bank of Mexico itself will credit the respective amount in the Unique Account of the Assigned Institution that has constituted the Guarantee in question. The Bank of Mexico will carry out the crediting referred to in this paragraph on the same Banking Business Day on which it has received the payment of said accessory rights, provided that such receipt occurs no later than 16:00:00 hours on that day. In the event that the Bank of Mexico receives the aforementioned payment after the indicated schedule, it will carry out the crediting in the Unique Account of the corresponding Assigned Institution on the next Banking Business Day.

20th. Early Maturity.- The Bank of Mexico reserves the right to terminate, in advance, some or all of the Foreign Exchange Coverages entered into with an Assigned Institution, in the event that this fails to comply with the obligation to constitute Guarantees referred to in Rule 16th of these Rules. In this case, the Bank of Mexico will send a written communication to the Assigned Institution that is a party to that Foreign Exchange Coverage, with at least one Banking Business Day's advance notice to the date on which the Foreign Exchange Coverage is to be considered terminated.

The Bank of Mexico will terminate the Foreign Exchange Coverages referred to in this Rule in the following manner: a) The Bank of Mexico will determine the market value of the Foreign Exchange Coverage entered into with the Assigned Institution in question in accordance with what is provided in Rule 15th of these Rules, corresponding to the Banking Business Day on which it intends to be considered terminated.

ANNEX 3 VALUATION OF SECURITIES

1. General valuation procedure. The Bank of Mexico will carry out the valuation of the Guarantee using the information sent to it daily by price providers (Providers) with whom it has the respective agreement. For the purpose of determining the valuation of the Securities that will be used to guarantee the Foreign Exchange Coverages referred to in the "Rules for the Foreign Exchange Coverage Auctions", contained in Circular 3/2017 of the Bank of Mexico, it may apply to each Security a discount factor on the valuation price obtained in accordance with the procedure described in this Annex. If applicable, the referred discount factors will be those corresponding to one-day term operations and will be made known to the Bidding Institutions by the Central Bank itself.

The valuation of fixed income Securities will be carried out by calculating a weighted average of the prices of the Providers, using random weights. The weighters are generated from a uniform distribution and subsequently normalized to ensure that the Bank of Mexico's valuation price is between the lowest and highest prices calculated by the Providers.

For each outstanding issuance, its dirty price, that is, including accrued but unpaid interest, as well as its clean price, that is, without including accrued but unpaid interest, will be determined.

1.1 Set of Securities to be valued in accordance with the procedure provided for in this section (Price Vector). The valuation will be carried out for the following Securities: • BONDE; • BPA; • BREM, and • CETE.

1.2 Calculation of the Price Vector. The valuation prices will be calculated as follows 2: A) If for Security x on the valuation date t there is at least 2 valuations from the Providers, the Bank of Mexico will determine the clean valuation price of that Security in accordance with the following equation: For each Security, on each valuation date, new weighters must be determined. The dirty prices in this case will be calculated using the same weighters as for the clean prices.

2 The Bank of Mexico may use same-day, 24-hour or 48-hour prices.

Viernes 24 de febrero de 2017 DIARIO OFICIAL (Primera Sección)

B) If for Security x on the valuation date t there is information only from the i-th Provider, the clean valuation price that the Bank of Mexico will determine for that Security will consider the clean price of that single Provider, modified in accordance with the following equation: C) If for the valuation date there is no information from any Provider for Security x, the Bank of Mexico will determine the clean and dirty valuation prices of that Security by repeating the one from the previous day.

2. Procedure to value Securities in their first placement. When there are no valuation prices from Providers, the Bank of Mexico will value the Securities in their first placement using the unique prices or rates or the weighted average rates or prices resulting from the respective auction.
