What the regs say is that IF you have a deposit taking branch/ATM, then that area must be in your AA. They do not say the opposite, but that is the practice.
Of course, the rules also mention about the lending, but crossing state lines opens a whole host of issues.
The big issue with LPOs is they are not branches so you don't have to include in the AA, but you absolutely must monitor the inside/outside ratios as you can get out of whack quickly.
The rules are:
"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. "
Are you in a multi-state MSA?
