1.21—Care of money and equities accruing to customers.
All money received directly or indirectly by, and all money and equities accruing to, a futures commission merchant from any clearing organization or from any clearing member or from any member of a contract market incident to or resulting from any trade, contract or commodity option made by or through such futures commission merchant on behalf of any commodity or option customer shall be considered as accruing to such commodity or option customer within the meaning of the Act and these regulations. Such money and equities shall be treated and dealt with as belonging to such commodity or option customer in accordance with the provisions of the Act and these regulations. Money and equities accruing in connection with commodity or option customers' open trades, contracts, or commodity options need not be separately credited to individual accounts but may be treated and dealt with as belonging undivided to all commodity or option customers having open trades, contracts, or commodity option positions which if closed would result in a credit to such commodity or option customers.
