12 CFR § 348.7 - Change in circumstances.
(a) Termination. A management official shall terminate his or her service or apply for an exemption if a change in circumstances causes the service to become prohibited. A change in circumstances may include an increase in asset size of an organization, a change in the delineation of the RMSA or community, the establishment of an office, an increase in the aggregate deposits of the depository organization, or an acquisition, merger, consolidation, or reorganization of the ownership structure of a depository organization that causes a previously permissible interlock to become prohibited.
(b) Transition period. A management official described in paragraph (a) of this section may continue to serve the FDIC-supervised institution involved in the interlock for 15 months following the date of the change in circumstances. The FDIC may shorten this period under appropriate circumstances.
