(a) A Bank shall require each member to maintain a minimum investment in the capital stock of the Bank, both as a condition to becoming and remaining a member of the Bank and as a condition to transacting business with the Bank or obtaining advances and other services from the Bank. The amount of the required minimum investment shall be determined in accordance with the Bank's capital plan and shall be sufficient to ensure that the Bank remains in compliance with its minimum capital requirements. A Bank shall require each member to maintain its minimum investment for as long as the institution remains a member of the Bank and for as long as the member engages in any activity with the Bank against which the Bank is required to maintain capital.
(b) A Bank may establish the minimum investment required of each member as a percentage of the total assets of the member, as a percentage of the advances outstanding to the member, as a percentage of any other business activity conducted with the member, on any other basis that is approved by the Finance Board, or any combination thereof.
(c) A Bank may require each member to satisfy the minimum investment requirement through the purchase of either Class A or Class B stock, or through the purchase of one or more combinations of Class A and Class B stock that have been authorized by the board of directors of the Bank in its capital plan. A Bank, in its discretion, may establish a lower minimum investment for members that invest in Class B stock than is required for members that invest in Class A stock, provided that such reduced investment provides sufficient capital for the Bank to remain in compliance with its minimum capital requirements.
(d) Each member of a Bank shall at all times maintain an investment in the capital stock of the Bank in an amount that is sufficient to satisfy the minimum investment required for thatmember in accordance with the Bank's capital plan.
