All revenues received by the board shall be accepted by the executive director and deposited with the Treasurer of the state to be credited to an account to be known as the Board of Veterinary Medical Examiners Fund. All expenses of the board shall be paid from the fund by vouchers signed by the executive director of the board and no part of the state's General Fund shall be expended for this purpose. Funds shall be a continuing account and shall not be subject to diversion to the State General Fund except to the extent that the balance in the fund at the close of any fiscal year exceeds the budget of the board by 200 percent, in which case the excess shall be transferred to and become a part of the State General Fund.
