At the margin, a seal with the National Coat of Arms, which reads: United Mexican States.- Treasury.- Ministry of

The

National Banking and Securities Commission,

after agreement

of its

Board of Directors,

having heard the opinion

of the Bank of Mexico and on the basis

of what is provided

by articles

50,

paragraphs first,

fraction I,

second

and fifth

and 98 Bis

of the Law of Credit Institutions;

as well

as 4,

fractions II,

XXXVI

and XXXVIII,

and 16,

and VI

of the Law of the

National Banking and Securities Commission,

and

CONSIDERING

That,

the Law of Credit Institutions

empowers this

administrative body

to issue general provisions to regulate the capital requirements

that credit institutions

must comply with,

for which they must consider

international banking uses

regarding adequate capitalization of institutions;

That,

the General Provisions

applicable to credit institutions

establish that credit institutions

may request authorization

from this

National Banking and Securities Commission to calculate their capital requirements

for credit risk

through models

based on internal ratings;

That,

the Basel Committee on Banking Supervision

through the regulatory framework

for banks,

Basel III post crisis,

proposed the adoption

of the standard denominated Output

Floor (revised capital floor)

for the calculation

of risk-weighted assets

of banks.

This floor is the

highest value between

the risk-weighted assets

calculated in the

following manner:

(i)

the methods established

and authorized

by the supervisor

under the

Basel framework

(both the standard

methods and those

based on internal models)

and (ii)

the 72.5% of

total risk-weighted assets

calculated using

exclusively the

standard methods.

The foregoing,

for the comparability

of risk-weighted assets

between institutions

that use standard methods

and those that

employ internal models,

and

That,

derived from the

above it is

necessary to update

the current regulatory

framework in order to

ensure the coherence of this

with international standards

and strengthen the

comparability, stability

and sufficiency of the

regulatory capital of the

Mexican banking system,

modifying the treatment

applicable to credit institutions

that opt to determine

their capital requirements

for credit risk

through a model

based on internal ratings,

in order to

incorporate the

Output Floor standard

(revised capital floor),

for which this

Commission has resolved

to issue the

following:
