Fit and proper criteria govern ownership of exchanges and clearing corporations, disqualifying convictions, insolvency, unsound mind, financial unsoundness. A fit and proper person for ownership of exchanges and clearing corporations must have fairness and integrity-including financial integrity, good reputation and honesty-and must not be subject to disqualifications such as convictions for moral turpitude, economic or securities offences; winding up orders; undischarged insolvency; regulatory debarments or other market-related orders within the specified post-order period; a finding of unsound mind; or financial unsoundness. The Board's decision on fitness is final.
