On Concentrations

ARTICLE 14. The identification of the economic agents referred to in Article 18, section II, of
the Law shall refer at least to the principal economic agents which together supply the
relevant market.

and sanctioned in accordance with Article 18, section III, of the Law, in addition the following
criteria shall be considered: 

I.The evaluation in the relevant market of the gains in efficiency which, in the terms of
Article 6 of this Code of Regulations, may derive from the concentration, which gains
must be accredited by the economic agents carrying out the said concentration;

When it is not possible to identify the indirect shareholders, this circumstance must
remain fully justified. 

ARTICLE 16. The conditions which the Commission may establish as binding upon the

The Commission may not impose conditions that are not directly linked to the correction of the effects of concentration. The conditions imposed must be in proportion with the correction that is intended. 

In the event of the Commission wishing to dictate a judgment whose purpose is to make the concentration in question subject to the fulfillment of certain conditions, notifiers may request that the Commission give prior consideration to their own proposals. 

ARTICLE 17. The notification of the concentrations referred to under the terms of Article 20 of

these must be notified before they have legal or material effects on Mexican national
territory. 

ARTICLE 18. The merging party, the party acquiring control of the companies or
associations, or the agent which is intending to carry out the act or produce the effect of

prejudice to its being carried out by any of the economic agents participating in the
transaction. 

ARTICLE 19. For the effects of Article 20 of the Law, the general daily minimum wage in

currencies for payment in the Mexican Republic, determined by the Banco de México and
published in the Diario Oficial de la Federación the day before the said notification. In the
event of failing to notify a concentration, the procedure set forth in Chapter V of this Code of
Regulations shall be followed ex officio, and the current general daily minimum wage and the
rate of exchange published by the Banco de México on the day before the transaction shall be
considered. 

ARTICLE 20. For the effects of Article 21, Section I, of the Law, the notification of the
concentration shall include:

or indirect share-holder must be identified, both before and after the
concentration, and that of the persons who currently have and subsequently
are to have control; 

VI. Description of the concentration, its aims and type of operation, and the draft of the legal act in question, as well as the clauses by virtue of which the parties
undertake not to compete and the reasons for the stipulation of the said
clauses;

When the notification fails to furnish all the requisites referred to in Sections I to VIII
above, the Commission shall give warning to the notifiers in order that, within a period not
exceeding five days, the required information be supplied; in the event of the said
information not being presented within the aforementioned term, the concentration shall
be deemed unnotified. 

In like manner, the concentration shall be deemed unnotified when any material
requested additionally to the aforementioned is not presented within the period specified
in Article 21, Section II, of the Law. The Commission shall only require such additional
material as is relevant for the analysis of the concentration in accordance with the criteria
set forth in the Law, which shall exclusively constitute the basis and motivation of the
corresponding requirement. 

The promoter shall be informed of the Commission’s decision to deem a concentration
unnotified within five days following the day on which the term for presenting the required
information expires. In the absence of the Commission issuing and notifying the
aforementioned decision, once the aforementioned period of five days has come to an
end it shall be understood that the promoter has presented the entirety of the information
required. 

The Commission may require information from other economic agents related with the
concentration, without it being construed thereby that the said agents are accorded the
nature of party to the concentration procedure. 

The economic agents shall present exclusively the information referred to in Sections I to
VII above, when they accredit before the Commission that it is plainly manifest that the
transaction will not have as its object or effect an increase in substantial power in the
relevant market or diminish, impair or prevent competition and free participation.

justified cause exists for said exemption. 

ARTICLE 21. It shall not be necessary to notify pursuant to Article 21, Section I, of the Law:

II.Transactions in which an economic agent has had in property or possession, directly or indirectly, over a period of at least three years, 98% of the shares or
partner’s capital contribution within itself or the economic agents involved in the
transaction. In this case, the economic agents shall only be obligated to notify

transaction, by means of a written declaration which shall contain:

Second Section 
On the Summons 

ARTICLE 32. For the effects of Article 33, Section II, of the Law, the summonsed shall make
reference to each of the facts expressed in the writ of alleged responsibility. Those facts
regarding which the alleged violator makes no declaration shall be deemed to be true,
excepting proof to the contrary; the same shall be the case should the alleged violator fail to
answer to the complaint within the period indicated in the aforementioned Section II. 
The alleged violator shall present its answer to the complaint and offer the evidence which it
considers relevant, on a sole or several occasions, but in all cases must do so within the

cause to deliver his or her report within the period allotted for this purpose, the evidence shall
be declared void. 

ARTICLE 36. The Commission may at any time have recourse to such evidence as it deems

for the expert and other witnesses, or regarding points that it deems relevant regarding the
inspection. The Commission shall establish the venue, day and time for the necessary
formalities to take place. 

ARTICLE 38. When an economic agent directly or indirectly involved in a proceeding refuses
to allow the examination or inspection ordered by the Commission, or fails to answer the
questions put to it, the said questions, whereby it is sought to ascertain the truth, shall be
