12 CFR 711.3: 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 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 $2.5 billion (or any affiliate thereof) may not serve at the same time as a management official of an unaffiliated depository organization with total assets exceeding $1.5 billion (or any affiliate thereof), regardless of the location of the two depository organizations. The NCUA will adjust these thresholds, as necessary, based on 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 NCUA will announce the revised thresholds by publishing a notice in the Federal Register.
