You will want your AAs to line up closely to your regulators definition for self-assessment purposes. Not all of those will receive a full scope exam and I know I would want to know how I was doing in the ones that would receive one. The regulation is pretty clear as to how they must be defined, I don't think you could have two MSAs in one AA.
§25.41 Assessment area delineation.
(a) In general. A bank shall delineate one or more assessment areas within which the OCC evaluates the bank's
record of helping to meet the credit needs of its community. The OCC does not evaluate the bank's delineation of its
assessment area(s) as a separate performance criterion, but the OCC reviews the delineation for compliance with the
requirements of this section.
(b) Geographic area(s) for wholesale or limited purpose banks. The assessment area(s) for a wholesale or limited
purpose bank must consist generally of one or more MSAs or metropolitan divisions (using the MSA or metropolitan
division boundaries that were in effect as of January 1 of the calendar year in which the delineation is made) or one or
more contiguous political subdivisions, such as counties, cities, or towns, in which the bank has its main office, branches,
and deposit-taking ATMs.
(c) Geographic area(s) for other banks. The assessment area(s) for a bank other than a wholesale or limited purpose
bank must:
(1) Consist generally of one or more MSAs or metropolitan divisions (using the MSA or metropolitan division
boundaries that were in effect as of January 1 of the calendar year in which the delineation is made) or one or more
contiguous political subdivisions, such as counties, cities, or towns; and
(2) Include the geographies in which the bank has its main office, its branches, and its deposit-taking ATMs, as well
as the surrounding geographies in which the bank has originated or purchased a substantial portion of its loans (including
home mortgage loans, small business and small farm loans, and any other loans the bank chooses, such as those
consumer loans on which the bank elects to have its performance assessed).
(d) Adjustments to geographic area(s). A bank may adjust the boundaries of its assessment area(s) to include only
the portion of a political subdivision that it reasonably can be expected to serve. An adjustment is particularly appropriate
in the case of an assessment area that otherwise would be extremely large, of unusual configuration, or divided by
significant geographic barriers.
(e) Limitations on the delineation of an assessment area. Each bank's assessment area(s):
(1) Must consist only of whole geographies;
(2) May not reflect illegal discrimination;
(3) May not arbitrarily exclude low- or moderate-income geographies, taking into account the bank's size and financial condition; and
(4) May not extend substantially beyond an MSA boundary or beyond a state boundary unless the assessment area is
located in a multistate MSA. If a bank serves a geographic area that extends substantially beyond a state boundary, the
bank shall delineate separate assessment areas for the areas in each state. If a bank serves a geographic area that
extends substantially beyond an MSA boundary, the bank shall delineate separate assessment areas for the areas inside
and outside the MSA.
(f) Banks serving military personnel. Notwithstanding the requirements of this section, a bank whose business
predominantly consists of serving the needs of military personnel or their dependents who are not located within a defined
geographic area may delineate its entire deposit customer base as its assessment area.
(g) Use of assessment area(s). The OCC uses the assessment area(s) delineated by a bank in its evaluation of the
bank's CRA performance unless the OCC determines that the assessment area(s) do not comply with the requirements of
this section.
