Sec. 1. The Corporation shall prepare an estimate of the funds necessary to defray reasonable expenses of administration in carrying on the work of the Corporation each fiscal year, and on the basis of such estimate, shall fix and levy the amount of admission fees, dues, assessments, and other charges to be paid by the members and issuers and any other persons using any facility or system which the Corporation, NASD Regulation, or NASD Dispute Resolution operates or controls. Fees, dues, assessments, and other charges shall be called and payable as determined by the Corporation from time to time; provided, however, that such admission fees, dues, assessments, and other charges shall be equitably allocated among members and issuers and any other persons using any facility or system which the Corporation operates or controls. The Corporation may from time to time make such changes or adjustments in such fees, dues, assessments, and other charges as it deems necessary or appropriate to assure equitable allocation of dues among members. In the event of termination of membership or the extension of any membership to a successor organization during any fiscal year for which an assessment has been levied and become payable, the Corporation may make such adjustment in the fees, dues, assessments, or other charges payable by any such member or successor organization or organizations during such fiscal years as it deems fair and appropriate in the circumstances.
