12 CFR 212.3: Prohibitions.

(a) Community. A management official of a depository organization may not serve at the same time as a management official of an unaffiliated depository organization if the depository organizations in question (or a depository institution affiliate thereof) have offices in the same community.

(b) RMSA. A management official of a depository organization may not serve at the same time as a management official of an unaffiliated depository organization if the depository organizations in question (or a depository institution affiliate thereof) have offices in the same RMSA and, in the case of depository institutions, each depository organization has total assets of $50 million or more.

(c) Major assets. A management official of a depository organization with total assets exceeding $10 billion (or any affiliate of such an organization) may not serve at the same time as a management official of an unaffiliated depository organization with total assets exceeding $10 billion (or any affiliate of such an organization), regardless of the location of the two depository organizations. The Board will adjust these thresholds, as necessary, based on the year-to-year change in the average of the Consumer Price Index for the Urban Wage Earners and Clerical Workers, not seasonally adjusted, with rounding to the nearest $100 million. The Board will announce the revised thresholds by publishing a final rule without notice and comment in the Federal Register.
