SR 00-14 (SUP)
October 23, 2000
Revised October 1, 2020

Note: This letter and attachment describe the use of the Strength of Support
Assessment (SOSA) in the Federal Reserve's foreign banking organization (FBO)
supervision program. On December 7, 2017, the Federal Reserve announced the
elimination of the SOSA and explained that it will cease assigning SOSA rankings on
the effective date of a final Payment System Risk (PSR) Policy that does not include
reliance upon SOSA rankings. See SR 17-13. On April 1, 2019 the Board approved
amendments to Part II of the PSR Policy to remove references to the SOSA ranking for
determining an FBO's eligibility for a positive net debit cap, the size of its net debit
cap, and its eligibility to request a streamlined procedure to obtain maximum daylight
overdraft capacity (84 FR 12049 (April 1, 2019)). The implementation date for these
amendments, and the elimination of the SOSA from the Federal Reserve's FBO
supervision program, is October 1, 2020. See also the Board's March 24, 2020 press
release and SR 17-13.

SUBJECT:

Enhancements to the Interagency Program for
Supervising the U.S. Operations of Foreign Banking
Organizations

Overview
The Interagency Program for Supervising the U.S. Operations of Foreign
Banking Organizations (the FBO Supervision Program), which was established in
March 1995, applies to all foreign banking organizations with a banking presence in
the United States. This presence can take the form of branches, agencies, Edge and
Agreement corporations, commercial lending companies, and subsidiary banks. After
more than five years of experience with the FBO Supervision Program, the Federal
Reserve, in cooperation and coordination with the other federal and state banking
authorities involved in supervising the U.S. operations of foreign banks, is taking a
number of steps to enhance the program. These steps include updating and
streamlining the Strength of Support Assessment (SOSA) process, informing FBOs
and home country supervisors of foreign banks' SOSA rankings, and creating a new
combined assessment rating for all of an FBO's U.S. branches, agencies, and
commercial lending companies (i.e., a combined ROCA rating).1
The principal changes to the FBO Supervision Program relate to the
SOSA process. SOSA rankings, which reflect an assessment of an FBO's ability to
provide financial, liquidity and management support to its U.S. operations, have been
found by U.S. supervisors to be an effective and reliable tool in supervising the U.S.
activities of foreign banks. These rankings are also used in connection with other

U.S. regulatory matters requiring a supervisory view of a foreign banking
organization.
For these reasons, the Federal Reserve and other U.S. bank supervisory
agencies have agreed to begin informing both the FBO's senior management and its
home country supervisor of the foreign bank's SOSA ranking. This step should
strengthen communications with bank management, as well as enhance informationsharing, collaboration and coordination between host (U.S.) and home country
authorities in the supervision of multinational banking organizations. Providing
SOSA rankings to home country supervisors will complement existing host-to-home
country information-sharing arrangements. Since 1995, U.S. supervisors have been
providing to home country authorities a composite rating that reflects a combined
assessment of an FBO's banking and nonbanking activities in the United States (i.e.,
the Combined U.S. Operations Rating). Such host-to-home communications are
important in helping home country supervisors carry out effective comprehensive,
consolidated supervision of multinational banking organizations.
The principal enhancements to the FBO Supervision Program are
outlined briefly below; details concerning these steps are set forth in the attached
policy guidelines, which supersede previous guidance issued by this Division in
SR letters 95-22 and 98-13. Reserve Banks will be provided with implementing
procedures for carrying out these program enhancements in the near future.
FBO Supervision Program Enhancements
The principal enhancements to the FBO Supervision Program are as
follows:
• More Frequent Updates of SOSA Rankings
The primary use of the SOSA, which is designed to reflect an
FBO's ability to support its U.S. operations, is to provide input to
the development and maintenance of a comprehensive supervisory
strategy for the U.S. activities of a foreign bank. To ensure that the
U.S. operations' supervisory strategy remains current and relevant,
it is essential that an FBO's SOSA ranking be updated whenever
necessary to reflect significant new information bearing on the
banking organization's overall strength-of-support capability.
While all FBOs will continue to be subject to, at a minimum, an
annual SOSA review, an update should be performed whenever
significant events occur that could have a material impact on an
FBO's ability to maintain the safety and soundness of its U.S.
operations.
• Streamlining SOSA Rankings
The five current SOSA ranking designations of "A" to "E" are
being replaced by three designations of "1" to "3," with "1"
representing the lowest degree of supervisory concern and "3" the
highest degree of concern. This change is being made because
experience with the program has shown that FBOs with SOSA
rankings of A and B generally have similar, positive or favorable
characteristics, and thus have resulted in very similar supervisory
strategies. At the other end of the scale, FBOs with "D" and "E"
rankings, while somewhat differentiated by the severity of their
problems, also warrant generally similar remedial supervisory

strategies. These patterns have emerged even though supervisory
strategies are individually tailored for all FBOs. As a result, the
number of SOSA rankings is being streamlined (i.e., reduced from
five to three) to more closely align FBO assessments with the
supervisory strategies for their U.S. operations.
Until now, the SOSA process has allowed for the inclusion of an
additional indicator (i.e., an asterisk) to flag certain significant
developments that were not otherwise captured as part of the basic
SOSA analytical factors, but which could have a material impact
on an FBO's ability to support its U.S. activities. These
developments include a pending merger, an emerging and
significant business line, or an operational control issue. The
changes to the SOSA process set forth in the attachment
incorporate these additional considerations more directly in the
SOSA factors, thus eliminating the need for the asterisk.
• Sharing of SOSA Rankings with the Foreign Banking
Organization's Senior Management and Home Country
Supervisor
Given the role of SOSA rankings in supervising foreign banks' U.S.
operations, going forward an FBO's SOSA ranking, and the
rationale for the ranking, will be provided to the FBO's senior
management and its home country supervisor. As mentioned
previously, this step should strengthen communications with the
FBO's senior management and enhance information sharing,
collaboration and coordination between host and home country
authorities in the supervision of multinational banking
organizations. Procedures for advising each FBO and its home
country supervisor of the FBO's SOSA ranking are described in the
attached policy guidelines.
• Assignment of a Combined ROCA Rating for Branches and
Agencies
U.S. bank supervisors will assign a "combined" ROCA rating for
all of an FBO's U.S. branches, agencies, and commercial lending
companies, in addition to ROCA ratings for the FBO's individual
offices. The combined assessment of the FBO's U.S. branch,
agency, and commercial lending company operations will in turn be
factored into the FBO's overall Combined U.S. Operations Rating,
which will continue to be a single composite rating that reflects the
U.S. supervisors' collective assessment of all operations (i.e.,
banking and nonbanking offices) of the FBO in the United States.
• Inclusion of an Institutional Overview
The SOSA will continue to be based on the factors originally
established in the FBO Supervision Program. However, the
underlying analysis, which supports the SOSA, is being expanded
to include an "Institutional Overview" of the FBO that documents
critical factors such as structure, business strategy and operations,
funding and liquidity, and governance. With this change, the
SOSA process for each FBO now will comprise two components:
(a) an Institutional Overview; and (b) a SOSA ranking. Under the
program, these components will continue to be supplemented by

the background "Reviews of the Home Country Financial System"
and "Home Country Accounting Practices." In addition, the
Reserve Bank or other supervisory agency that is responsible for
preparing the SOSA for the FBO will also have the responsibility
to prepare the Institutional Overview.
• Modification of Period for Supervisory Input
Comment periods for input from fellow U.S. supervisors on drafts
of FBO supervision program documents will be independently
determined by the authors of the documents based upon the
magnitude of any issues being addressed. However, in the case of
an upgrade or downgrade of an FBO's SOSA, the author must
designate a deadline for comments of no less than nine calendar
days from the issuance of the notification of the proposed change in
the SOSA. This should provide sufficient time for all interested
supervisory parties to consider and review the important issues
involved in the SOSA determination.
• Enhanced Supervisory Strategy Discussion
The "Supervisory Strategy" section of the SOSA is being moved to
the "Supervisory Plan." Going forward, the latter will include a
fully developed supervisory strategy that specifies clear objectives
and well-defined examination and other review activities for the
FBO's entire U.S. operations.
• Applications and the SOSA Process
FBOs entering the United States will be subject to the SOSA
process from the date that they are approved to establish their first
U.S. banking presence. The application process for the first U.S.
office should provide sufficient information about the FBO,
including its system of home country supervision and accounting
practices, to perform a SOSA review and determine an initial
SOSA ranking.
• Individual SOSA Documents
Each FBO must have a discrete, individual document setting forth
its SOSA ranking; multiple SOSAs should no longer be combined
in a single document for a homogeneous group of FBOs.
These changes to the FBO Supervision Program, especially those related
to SOSA rankings, have been discussed with the federal and state supervisory
authorities participating in the program. The Reserve Banks' continued strong support
of federal and state efforts to supervise the U.S. operations of FBOs in a coordinated
and consistent fashion that is risk-focused, burden-sensitive and cost-effective is
essential to the success of the United States as a host country supervisor.
Reserve Bank staff should distribute this SR letter to the U.S. offices and
the head offices of FBOs with operations in the United States, and to the local offices
of all federal and state bank supervisory authorities in their district.

Notes:
1. SOSA rankings and ROCA ratings are supervisory tools used by U.S. supervisors
to carry out their responsibilities for overseeing the U.S. activities of foreign banks.
SOSA rankings reflect an assessment of a foreign bank's ability to provide support for
its U.S. operations. The ROCA system represents a rating of the risk management,
operational controls, compliance and asset quality of an FBO's U.S. activities. Return
