- Definition

Carrying amount as of the balance sheet date of the capitalized costs of obtaining memberships that provide the entity, typically a broker-dealer, with the right to do business on trading exchanges (such as stock or commodity exchanges) in which the entity or its employees are members. Memberships are usually registered in the names of individuals who are affiliated with the broker-dealer. A membership held in the name of an individual is considered to be an asset of the broker-dealer if it is held by the broker-dealer under an agreement (such as an ABC agreement) that would require the member, upon leaving the broker-dealer, to do one of the following: a) Pay the member organization the amount necessary to purchase another membership (if the named individual wished to retain the membership); b) Sell the membership and pay the proceeds over to the member organization; or, c) Transfer the membership for a nominal consideration to a person designated by the member organization and satisfactory to the exchange.
