All moneys held in the Capital Reserve Fund, except as hereinafter provided, shall be used solely for the payment of the principal of bonds of DSHA as the same mature, the redemption or purchase of bonds of DSHA, the payment of interest on such bonds of DSHA or the payment of any redemption premium required to be paid when such bonds are redeemed prior to the maturity. Moneys in the Capital Reserve Fund shall not be withdrawn therefrom at any time in such amount as would reduce the amount of the Fund to less than the maximum amount of principal and interest maturing and becoming due in any succeeding fiscal year on all bonds of DSHA then outstanding, except for the purpose of paying principal and interest on bonds of DSHA maturing and becoming due and for the payment of which other moneys of DSHA are not available. Any income or interest earned by, or increment to, the Capital Reserve Fund due to the investment thereof may be transferred by DSHA to any other fund of DSHA to the extent it does not reduce the amount of Capital Reserve Fund below the maximum amount of principal and interest maturing and becoming due in any succeeding fiscal year on all bonds of DSHA then outstanding.
