It looks like traders with a CME seat pay less exchange fees than traders who lease their seats. Is this the same for NYMEX and COMEX seats? Do traders who own a NYMEX seat or COMEX seat pay less exchange fees than traders who lease their seats? (I can't seem to find this info on the cme website http://www.cmegroup.com/company/clearing-fees/ It only shows the fee for members but not for those who decide to lease.)
